It's all abstract destiny, you're one emperor through the ages

Chapter 138 Digging and digging in the tall and long mountains~
Early the next morning, Hua Chengyu went down to the forest in person.

He wasn't chasing Bamdan, nor was he gathering the defeated army.

The South Vietnamese natives and Zhang Yiping searched for a long time, but they couldn't find the defeated Han army, so naturally he couldn't find it either.

Hua Chengyu just pressed the map given to him by the emperor in his hand, and found an extremely hidden mountain.

He swung the big knife in his hand and almost chopped down the nearby weeds and broken wood, so he saw some clues.

"Look at the drawing on the map, there should be a hole here?"

Hua Chengyu was uncertain, but there was no other suspicious place nearby.

So, I had no choice but to face the ground, hold a knife, and scratch and stab like a fool.

After poking it for a while, he felt something was wrong.

The knife hit something.

He simply fell down and picked up the nearby mud with his hands.

After pawing for a while, a wooden board was suddenly pulled out.

It turned into rain, three times, five divisions and two, and the wooden board was removed. Under the wooden board, there was another layer of mud.

He stripped off the layer of mud again, and saw another board.

After the second board was removed, a hole was revealed.

"That's it."

Hua Chengyu let out a long breath, exhausted to death.

Such a small mouth, unexpectedly, has been sealed with so many layers.

He went straight down to the entrance of the cave. The tunnel seemed to be very deep. It was deep on the outside, but it was also deep on the inside.

Even if there is no block of wood and soil, the fruit is exposed, but it is simply hidden under the control of trees and weeds, so it is not easy to be found.

After walking in the rain for a while, he felt that he had come to an end, because he touched a wall of earth.

In the darkness, he stretched out his hand and touched the top of his head.

"Fix it with wooden boards, that's right, it's here."

Hua Chengyu continued to hold the knife, and reached out to dig out the connection between the plank and the earth wall.

The two are not tightly connected, as long as the surrounding soil is dug out, the board can be easily removed.

Then, after turning into rain and digging out the planks one by one.

With a soft sound, a large amount of soil fell, and then the earth wall also fell down.

After waiting for a while, the soil stopped falling, turned into rain and patted the soil on the body, stepped on the wooden board, and then officially entered the tunnel.

"Who?!"

At the head there was a general of the Han army, holding a knife against him.

"Imperial bodyguard, turn into rain."

The soldier immediately relaxed his vigilance, turning into rain in the army, he is still somewhat famous.

The army has been guarding the emperor's side all the time. They didn't know that there were genuine senior generals in Changshan, and Hua Chengyu should be the only one.

Moreover, this exit was so blocked that it was impossible for the soldiers of the Cochin Kingdom to discover it.

According to the emperor's instructions, this place is also used as a contact point.

"There should be news from His Majesty, and we can probably start fighting."

The guard soldier thought so in his heart, but he didn't just let Hua Chengyu in.

"Where's the token?"

"here."

Hua Chengyu handed out something, and the soldiers touched it a few times, and felt that there was nothing wrong with it:
"Go in, Master Chen and General Li are both in the largest tunnel."

"You should have a map, right?"

"Follow the map and you will find it."

"Have"

It turned into rain and entered the tunnel, with and without a map, the difference seems not too big.

After all, the tunnels on this map have seven bends and eight turns, are connected everywhere and have their own uses, so it is really not easy to walk.

After walking for a while, he got lost.

It was only under the guidance of the soldiers of the Han army who had been hiding in the tunnel earlier that they saw Chen Fujia and Li Jingji who had stayed in the tunnel all night.

The two of them had no energy, and their breathing was a little dull.

It can be seen that it has turned into rain, and there is a happy look on the face.

Chen Fujia was even worse, he was a dignified Chen family from Yingchuan, he was born in a famous family, but he had to learn from a field mouse, struggling in the tunnel, so he said eagerly:
"Your Majesty has taken the Changshan Holy Land??!"

"Take it."

It turned into rain, clouded and confused for a while, he left in a hurry, and the emperor didn't explain much to him.

But what's going on here?

After the defeat, why were the Han troops fleeing in all directions in the tunnel?
And seeing him coming, do you know that you have won the Changshan Holy Land?

Hua Chengyu suddenly felt a feeling of being abandoned by the world.

Chen Fujia knew it, Li Jingji knew it, Dian Chu probably knew it, and the soldiers in the tunnel all knew why.

Why doesn't he know? ? !

"It's good to win it. Winning the Changshan Holy Land means that the most difficult South Vietnamese natives have been solved. It seems that now is the time for us to play."

Chen Fujia moved his muscles and bones, but he still couldn't straighten up.

In the tunnel, after all, it is not wide.

"Master Chen, tell me, what is going on here?"

Seeing this, Hua Chengyu felt even more impatient and asked impatiently.

Chen Fujia made a look of bewilderment, and said:
"True, everyone knows that Your Majesty is good at attacking acupuncture points. Aren't you one of the eight hundred imperial guards who attacked Zhang Huaiyang at night?"

"Master Chen, please state clearly that I can cooperate with you."

It is still urgent to turn into rain.

Of course he also knew that this was a tunnel, but when was the Tama tunnel dug?
How did you guys get in here again?
Could it be that even yesterday afternoon's big defeat was fake?
Is he alone in the dark?

This is obviously catching honest people and cheating to death!

Seeing Hua Chengyu like this, Chen Fujia was secretly happy.

I just felt that the gloomy and damp air in the tunnel was gone, and I felt a lot more comfortable.

"Your Majesty led his troops deep into the forest in order to chase down the natives of South Vietnam."

"But those South Vietnamese aborigines have lived in Changshan for generations, and crossing mountains and ridges is like walking on flat ground."

"Even though our army is well-armored, we have specially recruited some South Vietnamese soldiers to supplement our mountain combat capabilities."

"Of course you can take some advantage, but how many advantages can you have?"

"Your Majesty is so talented, how could he be so unwise to fight in the mountains and forests with the South Vietnamese natives?"

"Even so, with the wisdom of a certain person, would he fail to see the danger of going deep into the mountains and advise him?!"

Chen Fujia's face was full of arrogance, no matter what happened to him, he put gold on his face first.

Then he took a deep breath, slowed down for a moment, and continued:
"When you exchanged gold and silver for the South Vietnamese natives in the market, His Majesty had already sent people to start digging tunnels."

"Do the math, we've been digging for a month."

"The land of Jiaozhi is mostly red soil and clay, and the same is true for Changshan. Moreover, it has been cloudy and rainy these days."

"The ground is wet and soft, which is more suitable for digging tunnels."

Hua Chengyu nodded and suddenly realized.

That's right, even the ground on the top of Changshan Mountain can be easily stood by the emperor poking the ground with a chessboard spear, which is of course suitable for digging.

But he was even more puzzled:

"The land in Cochin is certainly wet and soft, but it has been rainy in recent days, especially yesterday, when it was pouring down."

"Even if Changshan has not turned into a vast country, it is very detrimental to the safety of the tunnel. Why can you hide in the tunnel?"

He is well aware of the disadvantages of tunnels, and it would be outrageous if the tunnels were not flooded.

At the beginning, Zhang Huaiyang sent people to tell the guards of the counties in Qiongzhou to attack the tunnels with water and fire.

It's just that before the guard made any preparations, the city had already been deceived by the emperor, so it was useless.

But these two methods, no doubt, can be very good for digging tunnels.

And now in the rainy day, although it is impossible to set fire, but under the storm, wouldn't the tunnel be flooded?

Seeing Hua Chengyu's repeated questioning, Chen Fujia nodded with a satisfied look on his face.

Changing into rain is much more fun than Dian Chu and Li Jingji.

One is holding back for a whole day and can't fart a few farts, the other is only going step by step and following the scriptures.

It's better to turn into rain, he will draw inferences from one instance, and there are a hundred thousand whys, which can satisfy his desire to show off.

Chen Fujia saw that there was a fan, so he patiently explained:

"It's natural, heavy rain has a big impact on tunnels."

"But in order to fight the enemy and protect themselves, the soldiers can only overcome difficulties and dig deeper, stronger, more responsible structures and more comprehensive functions."

"As the saying goes, water flows downhill, so excavations will be made in the mountains, and even some hidden caves will be combined to gradually develop the isolated caves into criss-cross tunnels."

"Some places that are prone to rainwater are also deliberately covered, and are closed with wooden boards, broad leaves, and soil."

"At the same time, the soldiers also dug a special channel for drainage."

"These optimized tunnels have greatly improved the concealment effect compared to the tunnels you used to attack the enemy camp at night."

"Don't say that you are not afraid of heavy rain, even if it is water attack, fire attack, smoke attack, all of them are coming, it is useless."

"You set fire and smoke on this side, and the other side must be sealed off, or you can just go through another tunnel and slip away."

It was too troublesome for Chen Fujia to talk when he saw Guangyong, and the breathing was not very smooth in this tunnel.

He simply gave Hua Chengyu the tunnel structure diagram drawn by the emperor when he taught the soldiers how to dig tunnels.

Hua Chengyu just glanced at it briefly, then took a deep breath, trying to ease his emotions.

As far as the tunnels written on the drawings are concerned, the excavation depth is generally between three and four feet, the width is about two feet, and the height is three to five feet.

On the top of the tunnel, logs, hard clay, and a small amount of copper and wood are used to make a protective roof about three feet thick.

The top cover can play a supporting role.

Inside the smaller tunnel, only the roof is supported.

For some large-scale tunnels, such as tunnels specially designed for Dian Chu to drill in, in addition to the top cover, additional support columns are also set up.

As far as the shape of the tunnel is concerned, most of them are in the shape of "B" and are inclined.

It can be seen at a glance that this is also designed to prevent heavy rain, so that the seepage can be discharged into the water storage pit or drainage tunnel.

The water storage pit at the corner can be used as a water gate to prevent the enemy from invading, and it can also be used as a well.

And judging from this number, there are probably only a few core generals of the Han army who hold authentic maps.

Even ordinary Han soldiers couldn't figure out how many tunnels they had dug in the past month!
Even though he was terrified in his heart, Kecheng Yu still had too many puzzles:

"Master Chen, we have to dig so many tunnels, and we have to conceal them and deal with them meticulously. Where do the materials come from?"

As soon as he asked, he felt a little stupid.

There are many dense forests in the country of Cochin, and the Han army is in the mountains.

Unlike the tunnels they used to dig in Qiongzhou City, all wood and bamboo materials were directly obtained locally.

"Looks like you know it too."

"In this long mountain, there are many forests. There are not only tall trees and bamboos for building materials, but also low shrubs and vines for cover."

Chen Fujia lowered his voice, and said with an inscrutable look:

"However, it's more than that!"

"In the market, you exchanged money with the natives of South Vietnam. They often brought wood, bamboo chips and other things to exchange, right?"

Hua Chengyu was taken aback for a moment, then sighed again and again.

That's right, the emperor ordered to trade with the natives of South Vietnam, the price was kept very low, and there was almost no profit.

But what they bought was not just deerskin, camphor, and herbs, which were useful to the Han army, or resold, and profitable.

Even the wood that can be seen everywhere has been charged a lot at a discount.

It can even be said that these items that can be easily obtained are the most traded these days.

After all, even if there are no valuable deerskins or herbs at home, you can still chop some wood.

At that time, Hua Chengyu thought that the emperor did everything he could to win the favor of the Jiaozhi natives.

He even scolded the white-eyed wolf a few times when those South Vietnamese natives who were taken away by Bamutan without knowing it were resisting the Han army.

But in fact, the emperor has been calculating people since he was trading with the natives of South Vietnam? ?
It's not that only the Han army is digging tunnels!

Even tens of thousands of South Vietnamese natives participated!
It can even be called a "Changshan National Project"!
"However, the source of building materials is not stable through the exchange with the South Vietnamese aborigines."

"The more important thing is the division of labor proposed by His Majesty."

"Accurately assign the tasks of each soldier. Some are responsible for digging the soil, some are responsible for lifting the soil up, and some are responsible for transporting the soil away and dumping it."

"Each song, each battalion, each contracted a section."

"For shallower tunnels, the excavation method is to excavate at both ends, that is, to dig a shaft of ten feet every hundred feet or so."

"Then from the shaft, both ends are excavated to the middle at the same time until they meet."

"That way, it's easier."

Hua Chengyu couldn't help it again, and asked:

"Such a large-scale operation, won't it be discovered?"

"If the tunnel is discovered during excavation, it will be useless!"

Could it be that it was a fluke that successfully dug it?
Chen Fujia laughed and said:
"This also depends on the power of the market."

"The market is not just to win the favor of the South Vietnamese natives, let them help us raise building materials to make up for the lack."

"At the same time, it is also using cheap and beautiful goods to attract the attention of the South Vietnamese natives and let them focus on buying and selling."

"Thus making the soldiers digging in the mountains and forests more concealed and less likely to be discovered."

"Our tunnels are all dug from the direction opposite to the market."

"Even some necessary equipment for digging tunnels can be transported from Nichinan County under the pretext of transporting goods."

"The transportation of large quantities of materials will not arouse the vigilance of cochin workers because of the large supply in the market."

Chen Fujia said proudly again:
"The mere Changshan dense forest is still not worth mentioning in front of His Majesty."

He didn't leave the emperor inside and outside the words, but his words and expressions seemed to be showing off himself.

In his opinion, no matter what he thought when he proposed to open a market and trade with South Vietnamese aborigines.

Anyway, the market not only won the favor of the South Vietnamese natives, but also made a lot of contributions in digging tunnels!

Then he is meritorious!
Hua Chengyu was not fooled by Chen Fujia, and he knew who deserved the credit.

Needless to say, this extremely precise way of digging tunnels must be the same as Nanyue dialect and Nanyue culture, which His Majesty learned deeply from the people.

Li Jingji, who had been silently beside him, let out a long breath.

He knew about tunnel digging and had been involved in it all along.

But I didn't expect there to be so many twists and turns.

From the books he has read, tunnel digging first appeared in the Warring States period.

"Mozi Preparing Acupoints" says that if the enemy digs tunnels to attack the city, the defenders should also go straight to the enemy, dig tunnels in the direction of the enemy's acupoints, attack the acupoints with the acupoints, and wipe out the enemy's troops underground.

In order to keep abreast of the situation of the enemy's acupoints, dogs are sent to be on duty at the mouth of each well acupoint.
Hundreds of years ago, Cao Hou, who was both an enemy and a friend of Emperor Zhaolie, was also a master of acupoint attack according to historical records.

The famous Bozhou ancient road was once an underground military battle road specially built by Cao Hou for military needs.

It was originally used to transport soldiers, and later used in various aspects such as siege, retreat, communication, ambush, etc.

However, I never expected that today, it surpassed any authentic combat in the past.

The method of small point attack has been delved into this level!
This is not in the book.

Therefore, when Chen Fujia was explaining, Li Jingji remembered it in his heart.

Keep every word and sentence in your heart, learn slowly and make progress gradually.

Seeing Hua Chengyu's attention, Li Jingji also listened attentively, and Chen Fujia pointed on the blueprint:

"See this, this is an authentic ventilation pipe, made of bamboo."

"It looks like it's tilted, like the painting is crooked, but it's actually done on purpose by His Majesty, because it needs to be installed tilted to prevent rainwater from pouring in."

"The orientation of the air duct is also particular. Your Majesty has specially checked the astronomical calculations so that the warm wind can blow into the damp tunnel."

"This concealment is the most critical point. It is necessary to hide the part exposed to the surface to prevent the enemy from following the vine."

"Some authentic ventilation pipes are simply installed in the bamboo forest, so they can't be found at all."

"And these exits."

Chen Fujia made gestures in various parts of the drawings:

"The entrance to the tunnel must be as small as possible to improve concealment."

"The smallest entrance is only one foot long, one foot meter, and can only accommodate a thin soldier at a time."

"Slim soldiers??"

Hua Chengyu listened, his whole body trembled.

Most of the soldiers who came to Changshan when they sent troops to Jiuzhen County this time were thin and not big.

Looking at it before, it seems that there is nothing.

I thought that the emperor was afraid that the rear of Rinan County would be unstable, so he deliberately left those burly soldiers who looked fiercer to deter the nobles in Rinan County.

He still remembered that at that time Chen Fujia even advised the emperor not to divide the troops, but to press the whole army to defeat the enemy with force.

Now that I think about it carefully, this stepping on the horse is entirely for the convenience of drilling the tunnel!
Seeing that Hua Chengyu couldn't hold back his normal expression at all, Chen Fujia's mouth almost dropped from shock, and he continued with a smile on his face:
"However, His Majesty has also set up an entrance with a length and width of more than three feet to facilitate entry and exit, and to transport some supplies."

"Material delivery?"

Hua Chengyu was stunned: "Your Majesty intends to use the tunnel to fight for a long time?"

Chen Fujia nodded:
"It was planned like this before. If you can't take down the Cochin natives quickly, you have to be prepared for a long-term battle."

"However, now that His Majesty has knocked down the top of the mountain in one breath, and even completely shocked the South Vietnamese natives with the power of thunder, there should be no need for a long-term battle."

"Next, it is enough to deal with the army in Zhang Yiping's hands."

Hua Chengyu and Li Jingji asked at the same time:

"How to deal with this?"

This is what they can't understand the most.

A well-dug tunnel is a good thing.

But what's the use of digging such a tunnel after all the hard work?

Just to let the soldiers hide?

This can only be defensive, not offensive.

But they want to take down the entire Cochin Kingdom and return to Qiongzhou as soon as possible!

Chen Fujia then slowly explained:
"Going deep into the forest, it is true that we are fighting on the chassis of the South Vietnamese aborigines, but the underground that has already been dug is our territory."

"Remember the battle yesterday afternoon?"

"During the heavy rain, our army was entangled by the natives of South Vietnam, and suffered from the enemy."

"It seems to be a big defeat, with more than 2 troops and only 5000 left in the end."

"In fact, most of them got into the tunnel under the cover of heavy rain and dark sky."

"Then His Majesty will personally lead the remaining soldiers and horses to deal with the South Vietnamese natives."

"As long as we get rid of the South Vietnamese natives who are walking across the mountains like walking on the ground, it will be even more difficult to find the tunnel with the help of Zhang Yiping's army."

"If they go deep into Changshan, they can only be slaughtered by our soldiers hiding in the tunnel."

The soldiers of the Han army were missing, but they didn't flee after a big defeat, but sneaked and hid.

This is Liu Ke's complete plan, and he has never been defeated.

Once the tunnel was dug, he directly forcibly made other people's home field, and Niu became his own home field.

It is equivalent to that the underground of Changshan has become a series of three-dimensional underground combat positions.

There is no need to consider the dense forest on the ground, which will affect the operations of the Han army.

The South Vietnamese aborigines are guerrillaring in the mountains and forests, well, it’s amazing, then we go directly underground, there are no mountains and forests at all.

"Among them, the most important thing is whether His Majesty can win the South Vietnamese natives led by Ba Mudan."

"If it doesn't work, another battle plan can be launched."

"But at that time, the soldiers have to be prepared to fight in the tunnel for a long time."

"But now the general trend has come, and our army has completely occupied Changshan."

"And Zhang Yiping must be even more anxious, eager to block our army in the long mountain."

"Even going one step further, forcibly attacking the Changshan Holy Land on the top of the mountain, which is regarded as a residence by His Majesty."

"At this time, everything is going according to His Majesty's plan."

"Zhang Yiping will certainly not have many worries, or have the idea of ​​​​holding back and retreating to advance, so he will definitely launch a fierce offensive."

Chen Fujia pointed to Li Jingji, and then pointed to the soldiers of the Han army in the tunnel:

"After all, in Zhang Yiping's eyes, the soldiers have scattered and fled in all directions. His Majesty only has a few thousand troops in his hands. He barely occupied the top of the mountain by virtue of the thunder."

"Now that you are here, it means that everything is going well. The South Vietnamese natives are destroyed and are developing in the best direction."

"The follow-up battle must be launched as soon as possible."

Chen Fujia raised his head and glanced at the zenith of the dark tunnel, as if he could see countless dead Cochin soldiers through the ground:

"The end of Cochin Kingdom has arrived."
