Han Xuan said: "Xianbei must be removed, but there is no hurry at this time. Now it is only necessary to send one assassin to Mobei to assassinate Kebineng, and once Kebineng dies, the Xianbei tribes will definitely fall back into chaos, and there is no need to worry. ”

"Do you have the right person?" Liu Du pondered for a while and asked.

"Yang Kun. This person is highly skilled in martial arts, and he was once a member of the Heavenly Tribulation Gate, and he is good at assassination. After Han Xuan finished speaking, Liu Du was also taken aback.

Han Xuan explained: "Ahem. This person has long been out of the Heavenly Tribulation Gate and is absolutely reliable. In addition, Gongsun Yuan and Gongsun Huang can be separated, and Gongsun Yuan can be rewarded to make him turn away from Wei. After Gongsun Yuan captured Xiangping, he ordered Tian Yu to lead his army to Youzhou at the same time to contain the northern military strength of Wei. At that time, I sent several armies to the Northern Expedition at the same time, and the great cause could be determined! ”

Liu Du thought for a while and said, "What if Gongsun Yuan fails? ”

"After Gongsun Kang's death, most of the military power was in the hands of Gongsun Yuan. Gongsun Huang is a puppet supported by the Wei State, and he is controlled everywhere, and Gongsun Yuan must have been opposed. If the two brothers attack each other, we can send Tian Yu, Xu Sheng, and Ding Feng to take the opportunity to march in a big way and take Xiangping. If Wei sent a large army to conquer Gongsun Yuan, it would be even better, and we could take the opportunity to go north. Han Xuan told all the possible situations and countermeasures, and Liu Du was even more respectful and jealous of Han Xuan.

Liu Du had no choice but to agree to Han Xuan's strategy, and sent Zhang Mi and Xu Yan to Liaodong with a large number of gold beads and precious jades by sea, and named Gongsun Yuan as the king of Yan. Han Xuan also secretly sent Yang Kun to the sea to Liaodong, and asked him to go deep into Mobei to prepare to assassinate Kebineng.

After Zhang Mi and Xu Yan arrived in Liaodong, they separated the relationship between Gongsun Yuan and Wei and Gongsun Huang, and conveyed the meaning of Liu Du and Han Xuan. Gongsun Yuan was really moved, and led his troops to besiege Gongsun Huang's mansion and imprisoned Gongsun Huang and the envoys of Wei.

After that, Gongsun Huang consulted with everyone and was named the king of Yan by Liu Duzhi.

The deputy general Jia Fan hurriedly admonished: "Wei State treats the lord and the duke above, not as a lowly; If you rebel now, it will be unpleasant. ”

Gongsun Yuan was furious and asked Jia Fan to be tied up left and right, ready to push him out and behead him. Joining the army Lun bluntly admonished: "Jia Fan's words are yes. Sage Yun: 'The country will perish, and there will be demons.' 'Strange things are often seen in this country, and the lord should avoid evil and be lucky, and not act rashly. ”

Gongsun Yuan was furious and ordered the warriors to tie up Lun Zhi and Jia Fan and behead them at the entrance of the city. The general was made Beiyan a marshal, and Yang Zuo was a general, stationed in various important places to guard against Wei.

The border officials reported to Emperor Cao Rui of Wei. Cao Rui was shocked and urgently ordered the Liao general Biqiu Jian to lead the army east to Xiangping, and carry the letter seal to edict Sun Yuan, the Taishou Gonggong of Liaodong, to enter Beijing.

Gongsun Yuan refused to obey the edict and sent troops to block the Wei army in the Liao Tunnel. The two armies fought, it was the rainy season, the water swelled, and Biqiu Jian saw that the war was unfavorable, so he had to withdraw his troops and return.

Cao Rui was furious when he learned of this, and demoted Biqiu Jian to Huainan to join the army under Cao Xiu's account. Jia Kui suggested that Cao Rui summon Sima Yi into the court to discuss.

Cao Rui looked at Sima Yi and said, "Today, I have an eventful time in Dawei, and Gongsun Yuan is opposed. I want to take Qing as a general and lead troops to fight against Gongsun Yuan, how many soldiers and horses does Aiqing need? ”

Sima Yi played: "As long as the minister has 40,000 elite soldiers, he can break the thief." ”

Cao Rui shook his head and sighed: "There are few soldiers and a long way to go, and it may be difficult to recover." ”

Sima Yi is very confident: "There are not many soldiers, but they can use wisdom and ears." Entrusting His Majesty to Hongfu, he will capture Gongsun Yuan to offer His Majesty. ”

Cao Rui asked: "What did Gongsun Yuan do?" ”

Sima Yi replied: "If Gongsun Yuan abandons the city and leaves, it is a plan to unite with Tian Yu; Defending Liaodong and rejecting the army is also a plan; Sitting in Xiangping is for the next plan, and he will be captured by the ministers. ”

Cao Rui was still a little worried: "How long will this go back and forth?" ”

Sima Yi thought for a while and said: "Four thousand miles of land, go to a hundred days, attack a hundred days, return a hundred days, rest for sixty days, about a year is enough." ”

Cao Rui frowned: "If Han Xuan and Liu Du enter the Kou, what can I do?" ”

Sima Yi presented three tips to Cao Rui: "The minister has made a policy to defend the palace, Your Majesty should not worry." ”

Cao Rui was overjoyed, and immediately ordered Sima Yi to lead Niu Jin, Hu Zun and other foot riders to ride 40,000 to conquer Gongsun Yuan, starting from Beijing, passing through Guzhu, Yuejieshi, and entering Liaoshui in June.

Sima Yi ordered Hu Zun to be the vanguard, and led the front soldiers to Liaodong to go down to the village first. The sentry horse urgently reported to Gongsun Yuan, and Gongsun Yuan ordered Beiyan and Yang Zuo to station 80,000 soldiers and horses in the Liao Tunnel, enclosing the trench for more than 20 miles, surrounding the antlers, which was very tight.

Hu Zun asked Sima Yi to repay Sima Yi, who adopted the strategy of attacking the east and attacking the west, first spreading multiple flags on the southern front, feinting to encircle the trenches, attracting the enemy's main force, and using the main force to cross the Liaoshui in concealment and force into the enemy's Xiangping base camp.

The generals were puzzled by this, and Sima Yi said: "The enemy's strong camp is just to exhaust my army, and if I attack the city, it will be in the right way." The ancients said that although the enemy is strong, those who have to fight with us will be saved if they attack it. Now its army is here, but its nest is empty. I pointed directly at Xiangping, the enemy army will be afraid, afraid and seek to fight, and it will be broken."

Just when Sima Yi made a detour to Xiangping, Bei Yan discussed with Yang Zuo: "If the Wei soldiers come to attack, Hugh will fight with them." The Wei soldiers came thousands of miles, the grain and grass were difficult to last, and the grain would be retreated; When he retreats, he will then attack him by surprise, and Sima Yi can be captured. ”

The two were discussing when they suddenly reported: "Wei Bing went south." ”

Bei Yan was shocked, and hurriedly led the army with Yang Zuo to save Xiangping.

A horse explorer had already reported to Sima Yi, and Sima Yi smiled and said: "Zhongwu has a plan!" ”

Sima Yi ordered Xiahou Ba and Xiahou Wei to lead one army to ambush on the shore of Liaoshui, and the two generals had already seen Bei Yan and Yang Zuo to lead troops. Both sides are clamoring and waving flags: there is Xiahou Ba on the left, and Xiahou Wei on the right, all of them will be killed.

Bei Yan and Yang Zuo had no intention of fighting and took the road. The two led the defeated army to retreat to Shoushan, and when Gongsun Yuan led his troops to arrive, they joined forces and returned to fight with the Wei soldiers.

In the melee, Xiahou Ba slashed Humility under the horse, and the Liao soldiers were in chaos. Xiahou Ba drove his troops to cover up, and Gongsun Yuan led the defeated army to retreat into Xiangping City, and held out behind closed doors.

The Wei army surrounded Xiangping City on all sides, at this time it was the autumn rain continuously, the rain fell for a month, the water depth of the flat land was three feet, and the grain ships carried from the mouth of the Liao River to the bottom of Xiangping City.

The Wei soldiers were not good at water warfare, they were all in the water at this time, and the army's morale was unstable. Pei Jing, the governor of Zuodu, entered the account and said to Sima Yi: "The rain does not stop, the camp is muddy, and the army cannot be stopped, please move to the mountain in front." ”

Sima Yi said angrily: "Arresting Gongsun Yuan is only on the eve of the day, and An Ke will move to the camp?" If there is any more talk, the campers will be killed! ”

Pei Jing had no choice but to retreat. After a while, Qiu Lian, the governor of the right capital, came to persuade again: "Our army is not good at water warfare, if Xu Sheng leads the Chudi water army to rescue at this time, our army will be in danger." Please move the camp to higher ground. ”

Sima Yi shouted: "My military order has been issued, how dare you disobey it!" ”

Sima Yi immediately ordered someone to push him out and behead him, and his head was hung outside the gate, so the army was shocked.

Sima Yi sent people back to Luoyang to urge grain, Cao Rong set up a court, and the ministers all played: "Recently, the autumn rain has been continuous, and it has not stopped for more than a month, and the people and horses are tired. It is also the use of troops in the south, and the consumption of grain in the country is very huge, so Sima Yi can be recalled, and the right to strike with Gongsun Yuan is gone. ”

Cao Rui said: "Sima Zhongda is good at using soldiers, making changes in danger, having many good strategies, and catching Gongsun Yuan will wait for a day." Why worry? ”

Cao Rui did not listen to the advice of the ministers and sent people to transport grain to Sima Yi's army.

Sima Yi was planning military aircraft in Dazhai, and after a few days, the rain stopped and the sky cleared. That night, Sima Yi went outside the tent and looked up at the stars. Suddenly, I saw a meteorite, dragging a light several zhang long, and fell to the southeast of Xiangping City.

The soldiers of all battalions were extremely shocked by this, and Sima Yi was overjoyed when he saw this, and said to the generals: "In five days, the starfall will behead Gongsun Yuan." In the coming day, we can attack the city with all our might. ”

The Wei army attacked day and night, the food in Xiangping City was exhausted, countless people died, and Gongsun Yuan's general Yang Zuo and others surrendered. And Tian Yu, Xu Sheng and others would have refused to defend the fortresses according to Han Xuan's instructions, and did not come to the rescue of Gongsun Yuan, and Gongsun Yuan was terrified.

In August, Gongsun Yuan sent Wang Jian and Liu Fu to ask for the siege to be lifted, and Sima Yi beheaded the envoy and issued a document severely reprimanding Gongsun Yuan. Gongsun Yuan sent Wei Yan to ask for the return of the hostages on a regular basis, but Sima Yi refused the hostages. Gongsun Yuan then prepared to break through from the south of the city, Sima Yi's troops broke through the breakthrough army, and Gongsun Yuan died on the edge of Liangshui.

After entering the city, Sima Yi ordered the slaughter of more than 7,000 men over the age of fifteen, the collection of corpses, and the construction of the Jingguan. Then he beheaded all the ministers below Gongsun Yuan, killed more than 2,000 people including the general Bi Sheng, incorporated 40,000 households, and moved to Shanggu, Yuyang and other places in Youzhou.
