After receiving the order, Altik ’s men began to prepare immediately because the city is relatively large. If it is really in the city, dig a circle around all around, the manpower and material resources consumed are too large, obviously not very Realistic, but they ca n’t determine where the enemy outside the city digs, so they ca n’t conduct targeted confrontation.

Therefore, it is an urgent matter to find out the location of the tunnel excavated by the enemy outside the city as soon as possible. For this problem, it is actually very simple. You only need to dig a few more deep pits under the city wall, and then bury it in an empty large tank. The top of the big tank is covered with a layer of cowhide, and people are sent to listen to the movement for 2 or more hours. As long as the enemies outside the city dig near the city wall, they can hear them very clearly. In this way, the enemy can dig the tunnel very clearly s position.

This technique appeared a long time ago, which is enough to show that Ji-hye of the ancients was still very difficult to deal with, knowing how to amplify the sound of the underground and how to determine the direction of the tunnel.

After finding the direction of the enemy digging the tunnel, you can take various means such as digging, water discharge, smoke discharge, fogging, etc. to eliminate the enemy digging the tunnel in the tunnel, defeating the enemy ’s siege attempt and achieving the final victory. .

After the expansion of Maia City, the area of ​​the city wall is relatively large, and in order not to miss any direction, a large number of water tanks must be placed on each side. If the distance is too large, you may not quite clear it. .

There are a large number of water tanks in the army, but it still can not meet the needs, so I have to borrow from the family of the old 100 surname. After all, it is to guard the city. The old 100 surname naturally will not object.

More than 1000 deep pits were quickly dug in the city, with an average spacing of only several dozen meters, which was completely enough. The cowhide-covered water tank was quickly put into the deep pits, and each deep pit was Many people take turns to listen to the movements. In order to save troops, many children in the city have been mobilized. Their ears are better than adults, and they can hear more subtle sounds.

For ease of management, a small officer is responsible for every 100 water tanks. There are 100 soldiers under his command, and there are also 200 temporarily recruited children. They will not simply monitor the sound in the water tank, as long as a strange sound is found , Will immediately report to the above.

With this arrangement, it only takes more than 1000 people to monitor the soldiers and horses. This force accounts for a small proportion of the guards and horses and will not affect the battle strength of the guards and horses.

After the monitoring tank was built, Artik and Ibrahim went to inspect them separately to encourage the guards who guarded the tank, so that they should not be afraid of hardships, and they must monitor without interruption.

Because children ca n’t stay up late, they ca n’t stay up late, so during the daytime, more children are monitoring, and at night it is the soldiers who are responsible for monitoring in batches, one batch in the middle of the night and one batch in the middle of the night. Individuals are responsible for monitoring multiple water tanks, so they need to walk back and forth so that they can avoid accidentally falling asleep.

Within a distance of about 100 meters, patrol back and forth and listen to the movements in the water tank. This is not at all the pressure, and the physical consumption is not very large. Moreover, if the soldiers on the siege side want to dig tunnels It will definitely not dig for a while and stop for a while, it must be digging the tunnel all the time, so as long as it is close to the city wall, it will be noticed by the soldiers in the city.

“The soldiers are working hard, how about it, or is there a little movement?”

Artic, who came to inspect, asked.

“City Lord, our soldiers are monitoring day and night. There is really no movement at all. It seems that the soldiers outside the city are digging very slowly and are not close to the city wall.”

The subordinate said.

Artick nodded and said: “I hope this is the case, you must continue to monitor, 10000000 can not be slack, 10000 as soon as the enemy troops come in, we will be all over.”

“Yes, Lord, we understand.”

The subordinate responded.

The soldiers and horses in the city are actively preparing for the defense, and at the tunnel excavation site outside the city, Ziyad personally guides the tunnel digging soldiers and solves various problems raised by the tunnel digging soldiers.

In order not to be discovered by the soldiers in the city, Ziyad chose the excavation site, which is a little farther away from Meiya City, so it is naturally more difficult to dig, not only more soil to be dug, but also, Digging, the thinner the air, the easier it is for people to breathe.

In an era without a blower, how to solve the tunnel ventilation problem is a big problem, and if this problem cannot be solved, the tunnel cannot continue to dig in, otherwise the soldiers inside will be held alive.

In the years of the anti-Japanese war in China, because there was no such weapon as Artillery, in order to deal with the Japanese turret ’s turret, the vast majority of working people thought of digging tunnels to bury the explosives under the turret. The turret will be blown up to heaven.

But when digging the tunnel, a big problem was encountered, that is, the more digging inside, the more dirty the air, some soldiers would sleep in the tunnel unconsciously, and even cause the soldiers to sacrifice, in order to To solve this problem, at the time, a rope was tied to all the soldiers who dig the tunnel, and it went all the way out of the cave. As soon as the situation was found to be wrong, the rope was pulled immediately to pull out the soldier who passed out, thus avoiding the sacrifice of the soldier.

This is enough to show that in the absence of a blower, digging tunnels will encounter the reality of lack of air inside, which may even cause death.

At present, the elite soldiers under the command of Qi Yade apparently also encountered this problem. Moreover, the tunnel they are going to dig is longer than the tunnel dug by the Chinese military and civilians in later generations. The problems they will encounter are naturally more serious.

“General, it’s getting harder and harder to dig inside, breathless, what should I do?”

The little officer in charge of digging the tunnel said distressedly.

Ziyad frowns saying: “It’s not that I didn’t dig the tunnel before, why is this problem so big.”

“General, we used to dig tunnels after we were near the city wall. Now, we are digging tunnels too far away from the city wall. We have already dug 500 steps. Now the suffocation feels stronger and stronger. If not It will be difficult to continue digging inside if you widen the hole. “

The subordinate said.

Ziyad shook his head and said: “The tunnel is now large enough to accommodate 3 people walking side by side. If you continue to increase the opening, it may cause the tunnel to collapse. If it is so bad, you can think of other ways.”

“General, in addition to enlarging the hole, there is another way to make some ventilation holes above the tunnel. With this ventilation hole, it will not be too stuffy inside.”

The subordinate said.

Qi Yade opened the mouth and said: “It’s okay to get some ventilation holes along the way, but the ventilation holes can’t be too large, otherwise, it will be easy to be found by the enemy. Use long spear to throw a hole above the tunnel. It should be Not difficult! “

“This is not difficult, but because there is more sand on it, you must use a hollow bamboo pole to support it. Only in this way can the ventilation holes be truly ventilated.”

The subordinate said.

Ziyad frowned, said: “If it is supported by a bamboo pole, it will be too obvious, and soldiers on the city wall will find it.”

“General, if there is no support from the bamboo pole, the sand will block the small holes and will not play the role of ventilation. The small bamboo pole, if it follows very far, it should not be found, because this goal is too small, It looks like a needle from a distance. “

The subordinate said.

Ziad nodded and said: “Okay! Then get a few try now, this General takes a look from 100 steps away.”

“Yes, general.”

Immediately after his subordinates received their orders, they brought various tools into the tunnel, and at the position of 100 steps into the tunnel, they smashed a hole upwards, leading to the outside, but when the long spear was removed, the opening was quickly The sand was blocked, and then they used a hollow bamboo pole to insert the hole just made, so that it was easy to get it, they immediately breathed in the fresh air outside.

After completing the mission, they immediately evacuated the tunnel and reported to Qi Yade. Qi Yade stood on a high place outside and saw the bamboo sticks protruding from the ground. Although it is not obvious, it can still be found. It can be found by careful observation. .

The most important problem is that the open space outside the city is full of sand and there is not a little vegetation, and a bamboo pole suddenly appears in a large piece of sand, just like a needle on a white paper, it is still obvious, although The color difference between the iron needle and the white paper is not much, but it is still easy to find.

“General, we are done, can we see it?”

Asked his subordinates.

Ziyad pointed at a small piece of bamboo pole that appeared in the distance, opened the mouth and said: “Won’t you watch it yourself?”

“It’s so small, It shouldn’t be noticed!”

Subordinates opened the mouth and said.

“It can be found no matter how small it is. Pull down the position of the bamboo pole. The less it is exposed, the less likely it is to be found. It is better to be flush with the ground so that you can hide yourself to the greatest extent.”

Ziyad said.

“Yes, general.”

The subordinates hurried to prepare, and pulled the bamboo pole down as required, but as soon as the sand fell, move it up again to ensure that the height of the bamboo pole was exactly flush with the ground, so that it would not be suddenly exposed. Hide yourself very well.

“General, can you still see if you are done?”

The men ran out of the tunnel and asked excitedly.

Ziyad pointed happily at the distance, opened the mouth and said: “There is no trace left, yes, nice and pretty, let’s go, let’s go and see.”

They walked 100 steps away, looked at a small black hole exposed on the ground, shouted immediately, the soldiers below responded immediately, and said the following situation.

“It seems that this method is feasible. As long as more such ventilation holes are arranged along the way, it can solve the situation that the tunnel cannot be penetrated. Putting a ventilation hole every 50 steps should be enough.”

The subordinates said happily.

Qi Yade said with a smile: “Then you are still stunned, hurry and prepare! As long as there is enough air, the soldiers working inside can also dig the tunnel faster.”

Soon, Qi Yard’s men began to punch holes in the ground along the tunnel. In order to prevent detection, the small holes were made very small. Moreover, the bamboo pole was flush with the ground, and it was difficult to be found. At least, at 50 It is difficult to find anything outside the step, and beyond 100 steps, it is simply impossible to see such a small hole.

Of course, Qi Yade dreamed that they would n’t think of their behavior that they thought they were cautiously. In fact, they had already been exposed. The 3 cavalry who broke into the city with breakthrough defense had already told Artic that they had discovered the situation. They began to guard against their authentic attacks, so their attacks will not be effective, and returning will cause significant losses to themselves.

After the air problem in the tunnel was solved, the speed of digging tunnels under Qi Yade’s soldiers was significantly increased, which was several times higher than before. After all, when there is not enough air, there are only a few soldiers working If there are too many people, it will cause increased air consumption.

Now, by drilling holes above the tunnel, the air quality in the tunnel has been greatly improved. In this way, more soldiers can enter the tunnel to work together. The soldier in front is responsible for digging the earth. The soldiers in the back can transport the excavated soil, which greatly improves labor efficiency and greatly improves the progress of digging tunnels.

As the progress of digging the tunnel increases, the tunnel is getting closer and closer to the city wall. In this way, the soldiers responsible for monitoring in the city can hear some movements.

The big tank closest to the enemy ’s tunnel position first heard strange sounds, but because of the distance, the sound was not very clear, but it was indeed heard.

After hearing the news, the soldier responsible for the monitoring was very excited and immediately reported to Artik.

Knowing this, Artick personally went to the position of the big tank and listened carefully. There was really sound. He could hear the sound in his old ears, which showed that there was real movement.

“How many large cylinders can hear the movement?”

Artik asked.

“The city master, 5 or 6 water tanks nearby, can hear the sound, but this one is the clearest. The left and right ones are not clear.”

Subordinates are replied.

Altick nodded and said: “That’s right, it seems that the enemy digs the tunnel in this direction. Let’s go to the city wall and see.”

After talking, I took a group of people to the city wall.

Standing on the city wall, Artic people could see the enemy battalion in the distance and the position of the enemy’s siege building equipment, and they could see 1000 enemy cavalry patrolling in 4 places.

“Urban lord, the siege equipment camp in front is the closest to us. It seems that the tunnel entrance is in the camp in front.”

A subordinate said.

Artik said with a smile: “Ziyad is really patient, actually digging the tunnel from that far away, dig! Let them dig slowly.”

After he finished picking up the telescope, he followed a possible underground route and conducted a careful search.
