In western Liaoning, the Gongsun family is a big family. This Gongsun family refers to the family of Gongsun Zhan, whose hometown is in Lingzhi, Liaoxi (now Qiananxi, Hebei).

Because of the system of the Han Dynasty, officials could not be officials in the hometown of the official himself and the hometown of the official's wife, so Gongsun Zhan would be an official in Youbeiping.

Liaoxi County, Yangle, now Lulongdong, Hebei, under the jurisdiction of 14 counties. The Han Chinese population is about 80,000.

Liaoxi is the base camp of the Wuheng people, and the general leader of the Wuheng people, Badun, is here, so there are about 100,000 Wuheng people in Liaoxi, and more than 100,000 Han people who were plundered by the Wuheng people also live in Liucheng.

If Gongsun Du wants to be the emperor and establish himself as the king, he must prevent the Han Dynasty from sending troops to attack, but fortunately, Liaodong is located in a remote area, and the only way to communicate with the Central Plains is Liaoxi County on the west side.

The location of the Han people in western Liaoning is the territory of Gongsun Zhan, and if you want to occupy western Liaoning, you must greet Gongsun Zhan. Taking advantage of the enthusiasm of subduing Wuheng in Liaodong, Gongsun Kang contacted Gongsun Chan in the name of Gongsun Du and sent someone to show goodwill to Gongsun Zhan. At this time, Gongsun Chan was busy attacking the Yellow Turban Army in the west, and he was also happy that the east had no worries, so he agreed. This made Gongsun Du and Gongsun Kang feel at ease and prepare to conquer the ethnic minorities on the northeastern border.

Like the Wuheng people in Liaodong, they also have their own separate territory in western Liaoning, a very large grassland. His base camp was called Liucheng (now Chaoyang City, Liaoning), and 200 miles nearby was the famous White Wolf Mountain. The Wuheng people don't know how to defend the city, they only like field battles, and they are easier to attack; The disadvantage is that the tribes are relatively scattered, and once the Wuheng people flee after defeat, it is not easy to chase.

In Liaodong's trick against Su Muyan, it can only be used once, and now no one in Wuheng will trust Gongsun Kang anymore. Hu Ren is like this, if you are good to him, he will only remember it for a while; He will remember you for the rest of his life and hate you for the rest of his life.

It is estimated that even if Gongsun Kang changes his course in the future and appeases and treats the Hu people well, no Hu nobles will believe him.

Still in Gongsun Du's Liaodong Hou Mansion, the strategists gathered together. Summarize the successes and failures of subduing Wuheng in Liaodong, and study the plan for the next step to capture Liaoxi.

Zhao Yun has already returned to Xuansu County to garrison, and it is impossible to be careless in dealing with Goguryeo. It's okay to be temporarily transferred for a few days, but not for a long time. The Goguryeo people who saw the needle would take the opportunity to attack Xuansu County and plunder.

There are still too few generals, and there are not enough people. Gongsun Kang clicked his lips, thinking in his heart where he could abduct some more war futures. If you don't have a wise general, it's good to fight. Gongsun Kang regretted a little that he didn't make the effort to find Dian Wei when he stayed in Chen.

"Although Badun is brave, it is still a piece of cake for us Liaodong Iron Cavalry. What we want to study is how to get the most out of the way with the least cost. Guo Jia spoke first.

Inside the three military sacrificial wines. Guo Jia is the leader, Xi Zhicai does not compete with him, Cheng Yu came late, and his qualifications are not as old as Guo Jia, so Guo Jia naturally spoke first.

Xi Zhicai nodded and said: "That's the case, our attention should be on how to maximize the elimination and capture of the Wuheng people, they are as cunning as foxes, once there are signs of defeat, they will run outside the fortress, but it is not easy to chase." ”

"Poison their water sources, or soak the corpses in their water sources, so that the Wuheng people can be infected with the plague." As soon as Cheng Yu opened his mouth, he was ruthless and unpredictable.

Everyone in the hall collectively shuddered, it was really scary to be a partner with this kind of guy. Who knows what he will do when he will be happy and give himself a bag of poison?

"The plague must not be considered!" Gongsun Kang immediately stopped Cheng Yu's dangerous thoughts. "It is difficult to control the spread of the plague, once it spreads to the outside world, our entire three counties in Liaodong will be finished."

"How's the fire?" Guo Jia was a little excited, and Cheng Yu's thoughts inspired him.

"Great idea!" Xu Miao first agreed. "Now it's about to be winter, and the grass on the prairie is dry and yellow. Let's pour some more oil on it. You can set a fire that shocks the world. ”

"That's the idea." Cheng Yu also nodded in agreement: "No matter how scattered the tents of the Wuheng people are, they are also set up on the grassland, and we will set the entire grassland on fire to see where they run." ”

The people sitting in the hall were all ruthless people, like Xun Yue, Wang Lie and other Confucians, Gongsun Kang deliberately did not invite them. In the future, the government and the army will be separated, and the great Confucians will still be suitable for pacifying the people and governing the local area after the war.

Treating the Hu people, no one felt that the fire was too cruel, but they all happily discussed the details.

Xi Zhicai said: "In winter, it should be a northwest wind. We need to start setting fires in the northwest direction, and at the same time send a large number of men and horses to intercept the Wuheng people in the southeast direction. "Look, even the direction of the wind when the fire is set on fire has been considered.

Gongsun Kang wanted to leave as many people as possible, but seeing that the strategists were so interested, even Gongsun Du touched his beard, smiled, and looked very happy, so naturally it was not easy to say something bad about the scenery.

Cao Huachun cautiously arched his hand, but said clearly: "Ladies and gentlemen, have you ever thought about the more than 100,000 Han people who were looted by the Wuheng people, they also live in the camp of the Wuheng people, and they will not be spared from a fire." ”

All the strategists came back to their senses and were a little embarrassed. In these years, no matter how fierce a person is, he has to pretend to be merciful, and no one dares to say that even Han slaves are burned to death.

Tian Chou coughed, breaking the embarrassing situation. "In that grassland, there is White Wolf Mountain, there is Liucheng, although Liucheng is only a soil city, but the fire can't burn in. Whether the people of Wuheng hide in the mountains or hide in the city, they can avoid being burned to death. ”

Tian Chou can be said to be the pass of Liaoxi, and in history, it was he who led the way for Cao Cao and attacked White Wolf Mountain.

When Gongsun Kang saw Tian Chou, he thought of Liucheng, then thought of White Wolf Mountain, and then thought: "There is a legacy of Jieshi in the east." This stone is the location of the Shanhaiguan in later generations.

To enter Liaodong by land from the Central Plains, it is necessary to pass through Jiji (Beijing) to Liaoxi. Since ancient times, there have been two roads from thistle to western Liaoning:

(1) The most famous one is the "Coastal Road", which is located in the narrow coastal plain, which is today called the "Liaoning West Corridor". This road starts from thistle, passes through Yutian, Fengrun, Yanshan Customs to Jinzhou.

You must know that none of the 14 counties under the jurisdiction of Liaoxi County in the Western Han Dynasty is located in the coastal zone between today's Jinzhou and Shanhaiguan. In the absence of bad weather, this road is directly connected to the inland counties of Beiping and Yuyang. And once there are heavy rains in summer and autumn, this road becomes an unfeasible road again.

(2) The other road is the "Lu Longsai" where Tian Chou worked as a guide, and the "Chronicles of the Three Kingdoms" records: "The old Beiping County is in Pinggang, and the road is Lulong, and it reaches Liucheng; Since the establishment of the armed forces, it has been broken and cut off for 200 years, and there is still a micropath to follow". This road is the line from Xifengkou to Lengkou in Hebei today, which was called "Lulongsai" in ancient times.

Gongsun Kang made up his mind to build a castle at the location of Jieshi, and named it Shanhaiguan.
