When Guangning and Liaoyang launched a vigorous campaign to grow their hair and change their clothes and recruit soldiers, Su Qin's persuasion work in Datong also achieved great success.

In fact, this success is also inevitable. After all, Su Qin is one of the two most famous columnists in Chinese history. Except for his junior brother Zhang Yi, no one can make a reason for his eloquence.

In the past, Su Qin set out from Luoyang and began to travel all over the six countries of Kwantung alone, successfully persuading the monarchs of the six countries to join forces to resist Qin, and hanging the seal of the six countries on his waist, relying on his three-inch tongue.

The monarchs of the six countries, who have deep grievances and contradictions, can still be persuaded by Su Qin to form a united front to fight against Qin, not to mention a local general who actually has not many options, it is even more handy.

After Su Qin arrived in Datong, he first stayed in Datong for two days, and never met anyone except Bai Jinxiu.

On the third day, he entered Li Yongnian's mansion with only one entourage.

An hour later, when he came out again, it turned out to be Li Yongnian, who was extremely respectful.

The next day, Li Yongnian's letter of surrender arrived in Su Qin's hands, along with 50,000 taels of silver tickets, a roster of the strength of the Datong garrison, and a general account of money and grain.

After Su Qin's mission was completed, he did not return immediately, but stayed in Datong for several days, visiting everywhere, talking with the people in the market, and even took a few guards to ride a horse to a hill ten miles away from Shanhaiguan and observed for half a day before returning to the city.

Although Bai Jinxiu was also full of doubts about Su Qin, a great talent who suddenly appeared, he didn't ask much, but just sent someone to protect his safety in secret.

In fact, Su Qin's great talent is not as weak as those who read later, but an all-rounder who cultivates both civil and military.

He and Zhang Yi's teacher, Guiguzi, is a real genius, and he seems to be the kind of all-rounder who was born to know.

No one knows Guiguzi's real name, no one knows where he came from, and no one knows where he learned his knowledge.

It was as if he were an all-knowing and all-powerful wise man who had fallen from the sky out of thin air, and he traveled all over the world to choose students for himself.

There are five of his most famous students, that is, Pang Juan, Sun Bin, Shang Ying, Su Qin and Zhang Yi.

It is said that Guiguzi himself is proficient in the knowledge of various sects and sects in the world, and when he teaches his apprentices, he chooses a professor according to the intentions and qualifications of his apprentices.

For example, Pang Juan and Sun Bin studied the soldiers, Shang Ying chose the Legalists, and Su Qin and Zhang Yi chose the vertical and horizontal arts.

But no matter which school you are studying, fighting swordsmanship is a must-learn skill.

It is said that in the past, after Su Qin went out of the mountain, he first went to the Qin country, and he encountered a group of robbers on the road, and Su Qin repelled the robbers with a sword and retreated.

Zhang Yi also has the legend of being beheaded on the battlefield.

Shang Ying was a master of swordsmanship, and was once assassinated by the Mo family as a tyrannical person when the Qin State first began to change the law, and Shang Ying escaped the assassination with his clever skills.

Needless to say, Pang Juan and Sun Bin became the general of Wei after Pang Juan came out of the mountain, and his military force was also good.

Sun Bin was famous for his resourcefulness in the impression of later generations, because he was jealous of Pang Juan, which led to the tragic punishment and disabled legs, so he could only sit in a wheelchair to serve as a military advisor for Tian Ji, the general of Qi State.

Therefore, Su Qin's own force value is not low, although it cannot be compared with a high-level military class like a knight, but it is not something that ordinary people can deal with.

After being in Datong for seven or eight days, Su Qin sent someone to return to Guangning with Li Yongnian's loyal letter and related accounts, but he took a few personal guards to Erlong Valley.

That's right, there are still two people in the Erlong Valley waiting for Su Qin to get it.

When Su Qin persuaded Li Yongnian to completely return to Jiangchuan, and went to Erlong Valley to persuade Cao Bianjiao and Hong Chengchou, the 60,000 troops who attacked Shengjing with Hu Zongxian as the commander had also arrived at Shengjing.

Gaizhou City was defended by Shanjia and became a transit station for the materials and money of the Northern Expeditionary Army.

Di Qing took 20,000 pioneers and went fifty miles. Hu Zongxian and Ran Wu led 40,000 Chinese troops to the rear.

During this period, the Manchu Qing also sent a number of small armies to harass and intercept, but they were all routed and driven away by Di Qing's vanguard army.

At this time, after Huang Taiji died of illness in the Manchu Dynasty, Dolgon was seriously injured and fell into a coma, and the internal contradictions gradually became clear.

The most important contradiction was that the Mongol tribes, the Han Eight Banners, and the Korean kingdoms, which had been conquered by the Manchus by force, all began to rebound after losing their strong suppression.

Especially after the Chahar tribe took the lead in surrendering to the Jiang army, the other tribes of Mongolia were also ready to move, and some people even began to contact Geldan privately, hoping that he could match up for him.

For example, the Khan of the Mongolian Dulbert Department raised troops against the Qing Dynasty and stood on his own, waving the banner of restoring the glory of his ancestor Genghis Khan, calling himself Tiandu Khan, and began to burn and loot other tribes and Manchu villages, and lured the Weng Niute and Tumut tribes to rebel one after another.

The Korean Peninsula is also not peaceful.

The tens of thousands of Manchu troops left in Korea to deter were also repatriated, and more than half were used to defend Shengjing. The remaining people were not enough to deter the three Korean countries, so the three countries also began to use various ways to disgust and test these Qing troops who stayed behind, and there were constantly various skirmishes, and the news of the disappearance of Qing soldiers occurred from time to time.

At the beginning, another auxiliary prince of the Manchu Qing Dynasty, Prince Zheng Zierharang, also sent troops to suppress it, but now the Manchu Qing Dynasty is like a broken ship leaking everywhere, often pressing the gourd to float the scoop, this side has just stabilized, and that side has begun to make trouble again.

Moreover, the real enemy of the Manchus, the Jiang army, was surging forward, and they could only use most of their forces to stay in Shengjing, and there were not many troops that could be sent out to quell the rebellion.

Now people's hearts are panicking, and anyone who is not blind can see that the Manchu Qing Dynasty has reached the critical point of life and death. Therefore, Zilharang did not dare to send the people of the Mongolian Eight Banners and the Han Eight Banners out to quell the rebellion, for fear that they would not only fail to quell the rebellion, but would become accomplices of the rebels.

The only people he could trust were the Manchurian soldiers.

However, the population of Manchuria was not large, and the total population of Manchuria was only about 100,000. If it weren't for the strong combat power to subdue the scattered Mongolian tribes and the inclusion of many Ming prisoners, this would have been able to have enough troops to cross Liaodong.

Now that the Mongols and the Han Chinese are no longer worthy of trust, they can only trust the Manchurian soldiers.

However, there were only 50,000 or 60,000 Manchurian soldiers, and this was all the men who could go to the battlefield, not the standing guards of various banners.

These 50,000 or 60,000 people have lost more than half of them in the previous battles with the Jiang army, and some of the rest are still distributed in the old city of Hetuala, where Nurha's red army is the lair.

There are less than 20,000 people left who can defend in Shengjing, and these 20,000 people have to defend not only the Mongolian Eight Banners and the Han Eight Banners, but also Shengjing, ready to fight to the death with the Jiang army.

In this case, the Jiang family army marched all the way, like a bamboo, and finally Chen Bingsheng went down to the capital.

A great battle that would decide the life and death of the Manchu state was about to begin.
