In the Southern Song Dynasty, I competed with Mongolia for the world

Chapter 295 Breakthrough Change
No matter how good his relationship with the emperor was, he would not dare to agree to go overseas so far.

We must know that in the Tang, Song and later Yuan and Ming dynasties, ships going out to sea basically stayed about [-] kilometers away from the coastline, so as to ensure that the ship would not sink.

The same is true for Zheng He's voyages to the West. Once your ship is too far away from the coastline, some disaster will occur and you will not be able to reach the shore in time, which will be very dangerous.

It was completely impossible to cross the Pacific at this time.

Of course Zhao Yurui didn't want to go to the sea now, at least he had to wait until he destroyed Mongolia.

When the time comes to take the Mongolian troops to sea, if the ship sinks, all the Mongolian troops will be killed.

Well, that's it.

Zhao and Rui had sex with themselves happily.

"When I get older, I really want to go see it." Zhao Yurui patted the map hard, then turned around: "Help me find some Dashi shipwrights, I want to learn Dashi's shipbuilding skills. "

Dashi can now build a large ship with a thousand people. This level is higher than that of the Song Dynasty. Zhao Yurui must learn from it.

"I obey the order." Pu Heli thought to himself, this matter is easy to handle.

"I heard that someone in Persia separated oil and obtained asphalt?"

Every time Pu Heli went to Persia to purchase goods, Zhao Yurui would send someone to follow him and at the same time go to the Persian area to see the local situation.

Persia had asphalt to pave roads in the eighth century, and their famous Zoroastrian religion also used petroleum isolates to burn.

If the oil can be successfully separated, higher quality gas oil, diesel and other products can be obtained.

"Persia does have this kind of thing." Pu Heli said that in Persia, the so-called bitumen appeared very early, and it was very useful. Persia used it on ships as hull coating in the fourth century.

In Cathay and Persia it was used primarily as a sealant or adhesive, but also as a building mortar, even as incense, and as a decorative pigment and texture on pottery, buildings, or human skin.

Of course, more can be used to waterproof the hulls of canoes and other water transportation vessels.

The use of asphalt in the embalming technology of Egyptian mummies is also very important. The ancient Egyptians also used asphalt very early.

Therefore, because Persia and China were rich in oil at that time, they used asphalt many years earlier than in the Song Dynasty.

How to separate oil is very important.

"Find some of my craftsmen and technicians. No matter what method I use, I want to learn the art of separating oil." Zhao Yurui knew that separation of oil requires heating of oil. He also tried to experiment in the Song Dynasty, but after thinking about it, he decided not to rush.

He wanted to know what containers and methods the Persians used to do this. After all, heating oil is very dangerous.

"I obey the decree." Pu Heli agreed happily. After all, it was not a difficult task.

"Pu Qing often goes to sea. Does he know that it is inappropriate for a boat to go to sea with a flat bottom?" Zhao Yurui asked again.

"Your Majesty is wise. Flat-bottomed boats can easily capsize when encountering strong waves and severe weather." Pu Heli said.

At this time, both the Song Dynasty and Persia already had pointed-bottomed ships, but both sides had their own advantages and disadvantages.

"Since it is easy to capsize, why do I find that most sea-going ships still use flat-bottomed boats?"

"Back to Your Majesty, flat-bottomed boats have a shallow draft and can dock in many ports. Moreover, sea-going ships sail close to the coast. If they encounter danger, they can dock immediately. However, pointed-bottomed boats have a deep draft and cannot dock in many places."

"We travel by sea mainly to bring goods."

"Flat-bottomed boats have a large load capacity, which is why most merchant ships are flat-bottomed."

"The pointed-bottomed boats have a small carrying capacity, so they are not used much."

Pu Heli patiently explained to Zhao Yurui that pointed-bottomed boats have many advantages: they are resistant to wind and waves, have deep drafts, and are fast, making them suitable for long sea runs.

Zhao Yurui said: "If I have to travel seventy or eighty thousand miles across the ocean, do I have to use a sharp-bottomed boat?"

"That's the truth." Pu Heli nodded.

The key is its resistance to wind and waves. Unlike a flat-bottomed boat, it is easy to capsize when encountering strong winds and waves.

Zhao Yurui asked again: "The ships nowadays are all horizontal sails, right?"

Pu Heli was stunned for a moment when he was asked, and then nodded: "Yes, Your Majesty." After all, this meeting was all about Hengfan, so he was a bit baffled by the question.

The biggest feature of a square-rigged sailing ship is that it is slow against the wind. It is really slow.

When Columbus explored later generations, he added a triangular sail to the horizontal sail. From then on, his two new sailing ships opened up a new understanding of overseas affairs for mankind.

Zhao Yurui didn't say much. After all, Pu Heli was a foreigner. He had already studied the jib in his shipyard and would try to install it on the ship in a while.

Once successful, this will be a breakthrough change. Coupled with the pointed bottom boat, the speed of the ship will directly enter the [-]th century. By then, it will be possible to cross the Atlantic and Pacific like Columbus.

Pu Heli chatted with Zhao Yurui for a long time. When he finally left, he looked at Zhao Yurui's huge map. He felt that one day Zhao Yurui would really go to the place where Zhao Yurui pointed his finger just now.

Jia Sidao waited for a long time outside before he saw Pu Heli walking out.

Pu Heli was wearing an official uniform of the Song Dynasty, but his face looked like a foreigner.

Jia Sidao couldn't help but take a few glances, and saw that after he came out, he was greeting people outside with a smile on his face.

There was a chamberlain standing outside. Jia Sidao didn't recognize him either, but Pu Heli took the lead in greeting the chamberlain: "Huang Duzhi."

This is Huang Shang, who has been promoted to the rank of magistrate.

Huang Shang also laughed along with him: "Marquis Kaiguo."

The Song Dynasty was very casual in granting marquisships to people outside the clan. In the end, hundreds or thousands of people were granted the title of marquis, most of whom were called founding marquises.

Shi Miyuan in original history was also the founding prince.

Of course, the location will be added before the founding lord.

For example, Puheli is the founding prince of Quanzhou County. No matter what prefecture or prefecture, they are all called counties.

Pu Heli also stopped to say a few words to Huang Shang. Jia Sidao sounded like he was asking, have you eaten, hello, good morning and other common nonsense.

But when it comes out of Pu Heli's mouth, it feels different and makes people feel comfortable listening to it.Jia Sidao thought to himself, this foreigner is very powerful, if he wants to learn from it, how can he be summoned by the emperor and be made a marquis?

After saying a few words, Huang Shang also turned around: "Nanyang Marquis, your Majesty has summoned you."

It turned out that the next person to be summoned was Nanyang Hou.

This Marquis of Nanyang was not wearing the official uniform of the Song Dynasty. He was wearing clothes that Jia Sidao had never seen before.

This man is none other than Puka, a Srivijaya businessman.

He controlled the sugar sold by the Song Dynasty to the islands around Srivijaya (Nanyang). He was also an important partner that Zhao and Rui met when they were kings of Wei.

Pu Heli said hello to Pu Ka again at this time, and Jia Sidao heard it clearly. It seemed that the two had made an appointment to have dinner together.

Puka happily agreed and strode in.

At this time, Pu Heli continued to greet everyone present, and Huang Shang followed behind to help him introduce.

Jia Sidao pricked up his ears and listened.

There was a man named Jin Qisun, who was from Korea, and another one was actually Japanese.

Jia Sidao was a little confused for a moment. All the people the Emperor of the Song Dynasty met were foreigners?
"This is Jia Guifei's younger brother Jia Sidao." At this moment, Huang Shang's voice rang in his ears.

Only then did Jia Sidao come to his senses, and Pu Heli was already in front of him.

"I have admired him for a long time. Mr. Jia is a handsome young man, and he is indeed a talented person." Pu Heli smiled and expressed his goodwill to him.

Huang Shang introduced to Jia Sidao that this was Pu Heli, the founder of Quanzhou County, and then added that he was a good friend of His Majesty.

When Pu Heli said the words "Emperor's Friend", he also showed a proud look on his face.

Who in the Song Dynasty dared to call himself the emperor's friend?
Only he, Pu Heli, could be called that, and the emperor had asked people to publicize it many times.

"Jia Sidao has met the Founding Marquis." Jia Sidao quickly said hello.

Pu Heli chatted with him casually for a few words, and then left the Xuande Hall under the watchful eyes of everyone.

Not long after, Puka also came out, also smiling.

The next person to enter was Jin Qisun, a Korean, and there was a Han with Jin Qisun. Later, Jia Sidao found out that the Han was an official of Jeju Island and a confidant of His Majesty the Emperor.

Jin Qisun is the younger brother of Jin Ruoxian.

At that time, Zhao Yurui followed Jin Ruoxian's route through Yan Ying, and then found Cui Yu of the Korean Quanqun, and bought Jeju Island from Cui Yu, thus having a place to train troops and build artillery.

There have been frequent transactions between the two parties in the past few years. Zhao and Rui also give various benefits to Cui and Jin every year, and the relationship between the two parties is quite close.

The relationship between the two countries also reached its peak in the history of Song Dynasty and Goryeo.

This time Jin Qisun came to the Song Dynasty, mainly because something happened near the Kingdom of Goryeo.

After Wokuotai succeeded to the throne, at the beginning of this year, he ordered his bodyguard (Huoerchi) to conquer Liaodong, Korea and Dongxia east of Salita.

In other words, Mongolia is now fighting on multiple fronts and is using troops against Liaodong.

Of course, Wokuotai over there didn't pay much attention to it. There were not many soldiers and horses, and the leading general was his own bodyguard.

Now the Mongols are fighting the remnants of the Jin Dynasty in Liaodong.

In the original history, they first pacified Liaodong, and then conquered Goryeo the next year, asking Goryeo to join them in fighting Dongxia.

Goryeo ignored Mongolia and ran directly to Ganghwa Island.

Then the Mongols conquered Goryeo again, but Salita was killed in battle, and the expedition to Dongxia had to be shelved.

After the Mongols destroyed the Jin Dynasty, Wokuotai ordered the prince Guiyou to conquer the Eastern Xia again, and then the Eastern Xia was destroyed.

The Mongols are now obsessed with destroying Dongxia, because Wokuotai failed to attack gold and suffered successive defeats. A victory in Liaodong is needed to prove his wisdom.

Moreover, in Liaodong, he went against all opinions and left many famous Mongolian generals unused, and arranged for his bodyguard Salita to lead the army, which really made the Mongolian people unconvinced.

"Dongxia was a country founded by Pu Xian and thousands of slaves?" After Zhao Yurui heard this, he turned around and looked at his big map.

This map will be adjusted every year after he takes the throne. He wants to make himself as clear as possible about the major forces in the surrounding areas so that he can make the fastest decision.

Mongolia is now going all out to cut down the gold. Unexpectedly, there is still an Eastern Route Army going to attack Liaodong. Zhao Yurui is very surprised.

Thinking again about the Mongolian army in the west, there are still soldiers and horses from the Western Expedition that have not returned. At this time, Mongolia is really powerful, and it will not use all its strength to attack any country.

Na Puxian Wannu, also known as Bald Pearl Dashi and Wanyan Wannu, was a general in the late Jin Dynasty and a Jurchen tribe.

He was originally the Xuanfu envoy of Jin and Liaodong, and he attacked Yeluliu brother. He was defeated and fled to Tokyo (today's Liaoyang City, Liaoning Province). In 1215, Pu Xianwannu rebelled against the Jin Dynasty and became independent, occupied Xianping, Tokyo, Shenzhou and other places, attacked Posufu Road (now southeastern Liaoning, where the rule is now Dandong), Shangjing City and other places, and established himself as the king of heaven. The name is Dazhen (also known as Dongzhen and Dongxia), Jianyuan Tiantai.

Due to the unfavorable war situation, they moved eastward to the area of ​​Haolan Road and Shipin Road. In October 1216, after the Mongolian general Muhuali wiped out most of Liaodong, Pu Xianwannu surrendered to Mongolia. As soon as Muhuali died in 1223, he immediately rebelled against Mongolia and stood on his own initiative, killing Yelv Nie'erge, the Youcheng governor of Liaodong Province appointed by Mongolia. .

He also sent an envoy to Korea to announce that "Master Genghis from Mongolia is in extinct territory and no one knows where he is, and Chixin (Temuge Ochijin) is greedy, violent and unkind, and has given up on the old good". At the same time, he also requested that Qingzhou in Eastern Xia (today's Beiqing ) and Goryeo Dingzhou (today's Dingping) each opened a business and continued trading.But after that, the Eastern Xia army often invaded Goryeo.

To say that Pu Xianwannu was trading with Goryeo and often beating Goryeo at the same time, Goryeo hated him and gritted his teeth.

But Goryeo knew better that Mongolia was the evil tiger.

Now Dongxia is blocking the front. Mongolia conquers Dongxia first, and even sends envoys to force them to attack Dongxia together.

Once Dong Xia was finished, Gao Li knew it would be his turn.

It should be said that the business delegation sent by Yan Ying to Goryeo in recent years has been effective. It has continued to promote Mongolian brutality in Goryeo and massacred cities everywhere in the Western Regions. Now even the Goryeo people are afraid of Mongolia.

This time Salita conquered Dongxia again and forced Goryeo to send troops. Goryeo was also panicked, so Jin Qisun was sent to ask for help.

After all, the Song Dynasty was a sovereign state.

And the relationship with Goryeo has been quite close in recent years.
