In the third year of Qinglong (235), Sima Yi was promoted to Taiwei and increased the number of feuds. The Shu general Ma Dai invaded the country, and Sima Yi sent Niu Jin to meet the attack and beheaded more than 1,000 Shu troops. Wudu Di Wang Fu Shuanghe Qiang Duan led more than 6,000 of his subordinates to surrender.

Pacify Liaodong

At the end of the Eastern Han Dynasty, when the warlords were fighting, Gongsun Du owned Liaodong. This separatist force has always rebelled against Cao Wei and maintained a semi-independent status. After Gongsun Yuan succeeded as the Taishou of Liaodong, he was even more inferior to Wei. Emperor Wei Ming was furious and sent Jingzhou Assassin Shi Wuqiu Jian to serve as Youzhou Assassin Shi, when the Liao water rose sharply, Wuqiu Jian returned unfavorably. The crusade was blocked, which made Gongsun Yuan even more proud. In the first year of the early Jing Dynasty (237), Sun Yuan, the former Taishou Gong of Liaodong of Wei, betrayed Wei and established himself as the king of Yan, placed hundreds of officials, and set the capital Xiangping (now Liaoyang, Liaoning). Gongsun Yuan sent Sun Quan to Nantong to worship the border people, lure Xianbei, and invade the north.

Sima Yi sent troops to Liaodong

In the first month of the second year of the early Jing Dynasty (238), Sima Yi led Niu Jin, Hu Zun and other 40,000 horsemen, starting from Beijing, passing through Guzhu, crossing Jieshi, and entering Liaoshui in June. Gongsun Yuan urgently ordered the generals Bei Yan, Yang Zuo and others to lead tens of thousands of cavalry, encircling more than 20 miles according to the Liaoshui moat, fortifying the walls and high bases, and blocking the Wei army. Sima Yi adopted the strategy of attacking the west from the east, first spreading a number of 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. Sima Yi said: "The enemy's strong camp is to exhaust our soldiers, and if we attack the city, it will be in their plan."

The ancients said that although the enemy is strong, those who have to fight with us will be saved if they attack it. Now their army is here, but the nest is empty. I pointed directly at Xiangping, the enemy army will be afraid, afraid and seek to fight, and it will be broken." Then the array was reorganized and advanced, and the enemy came out to intercept it. Sima Yi said to the generals: "The reason why I didn't attack his camp was precisely because I had to wait for the current situation. So he commanded the Wei army to attack hard, won all three battles, and then took advantage of the victory to enter the siege of Xiangping.

When Gongsun Yuan heard that the Wei army was attacking, he begged Sun Quan for help, and Sun Quan also sent troops to support him, and wrote a letter to Gongsun Yuan: "Sima Yi is good at using his troops to move forward, and he is deeply worried about his virtuous brother." "It happened to rain heavily, the water in Liaoshui soared, the ground was several feet flat, the Wei army was afraid, and the generals wanted to move to camp. Sima Yi ordered those who dared to move the camp to be beheaded, and the governor ordered Shi Zhangjing to be beheaded in violation of the order, and the army's heart was at ease. Gongsun Yuanjun rode the rain out of the city, collected firewood and herded horses, and was safe.

The Wei generals asked for an attack, but Sima Yi refused to allow it. Sima Chen Gui asked Sima Yi: "Back then, when we attacked Shangyong, we advanced in eight ways, day and night, so we were able to capture Jiancheng and kill Meng Da in ten and a half years." Why is it moving more slowly this time from afar? Sima Yi said: "At that time, Mengda's army was small and the food could support a year, our army was four times that of Mengda, but the food was less than a month. It was feasible to attack one with four or one, even if half of the people were killed or wounded, and at that time, regardless of the casualties, it was precisely to buy time for the limited grain and grass.

Now that there are many enemy soldiers, our army is small, the enemy has less food, we have more food, and in the event of heavy rain, it is impossible to fight quickly. From the moment I sent out the troops, I was not afraid that the enemy would attack, but that they would flee. Now that the enemy's food and grass are running out, and our army's encirclement has not yet been closed, if they plunder cattle and horses now, they will be forced to flee. The soldier is treacherous, and the good is changed by events. And by virtue of the abundance of men and the great water, they refused to be taken away in spite of hunger. At this time, it is better to stabilize the opponent and not scare the enemy away for small profits. "Sima Yi will do what he plans and deliberately show weakness. The imperial court heard that the rain was a strong enemy, and many people asked for Sima Yi to be recalled. Emperor Wei Ming said: "Sima Yi is in danger to make changes, and the capture of Gongsun Yuan is just around the corner." ”

After a month, the rain stopped and the water gradually receded. The Wei army completed the encirclement of Xiangping and attacked day and night. The food in the city was exhausted, and there were many dead, so he surrendered Yang Zuo and others. At that time, the city became more and more frightened, Gongsun Yuan was also very frightened, in August, Gongsun Yuan sent the prime minister Wang Jian, the imperial historian Liu Fu to ask for the siege to be lifted, Sima Yi beheaded the messenger, issued a letter to severely reprimand. Gongsun Yuan also sent the guards to ask for a date to be sent to the hostages, but Sima Yi refused to take the hostages. Gongsun Yuan wanted to break through from the south of the city, but Sima Yi's troops broke his 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. Later, he beheaded all the ministers below Gongsun Yuan, killed more than 2,000 people including the general Bi Sheng, and incorporated 40,000 households.

Sima Yi released Gongsun Gong, who was usurped by Gongsun Yuan, and built tombs for Lunzhi, Jia Fan and others who were persecuted by Gongsun Yuan to commend their descendants. The order said: "In ancient times, when a country was conquered, only the stubborn and vicious people in it were killed. All those who have been affected by Gongsun Yuan will be forgiven. If the people of the Central Plains are willing to return to their hometowns, they will do what they want. ”

At that time, some soldiers in Sima Yi's army had cold clothes and asked for short jackets, but Sima Yi refused to give them, saying that "the official goods of the shirts are selfless." So he went to the imperial court and dismissed more than 1,000 soldiers over the age of 60 from military service and sent them back to their hometowns. Within the original one-year period, the victory class division. Emperor Wei Ming sent envoys to Ji to reward the troops, and increased Sima Yi to eat Kunyang County, a total of two counties before and after. Cao Wei's decades-long Liaodong problem was finally completely resolved.

Entrusted to the lonely ministers

Originally, the imperial court asked Sima Yi to go to Zhenguanzhong. But when he arrived at the White House, there was an edict calling him to return to Beijing quickly, and within three days, the edict was five solstice. Emperor Wei Ming's handwritten book said: "I can see it from the side, and when I arrive, I will go straight into the pavilion and look at my face." It is said that when Sima Yi was in Xiangping, he dreamed that Emperor Wei Ming was pillowing on his lap and said, "Look at my face." ”

He looked down and saw that Emperor Wei Ming's face was different. Now when I saw the edict, I was shocked, and I took the chaser to travel day and night, from the white house to the capital, more than 400 miles, and arrived overnight. Next to the royal bed in the Jiafu Palace, his eyes were full of tears, and he asked about the disease. Emperor Wei Ming took his hand, looked at the crown prince King Qi, and said, "I will trust you in the future." Death is bearable, I endure death and wait for you, you have to see each other, and there is no revenge. ("Three Kingdoms, Wei Shu, Ming Emperor Ji" is "I am very ill, and the future will belong to the king, and the young son of Jun Qi and Shuang Fu.") I have to see you, and I have nothing to hate. ）

On the same day, Emperor Wei Ming died. It was the first month of the third year of the beginning of the Jing dynasty (239). Cao Fang, the king of Qi, succeeded to the throne at the age of eight, and Sima Yinai and the general Cao Shuang accepted the edict to assist the young master. King Qi ascended the throne, Sima Yi served as a servant, a festival, a governor of Chinese and foreign armies, a record of Shangshu, and Cao Shuang each commanded 3,000 elite soldiers, and ruled the government together. Cao Shuang wanted to squeeze out Sima Yi, and wanted Shang Shujuan to pass him in advance, so that he could make a statement to the Son of Heaven and reappoint Sima Yi as the great Sima.

The courtiers thought that many of the great Sima had died in office in the past, which was unlucky, so they appointed Sima Yi as the Taifu, following the example of Xiao He, the prime minister of the Western Han Dynasty. With the prince Sima Shi as the free cavalry attendant, the three children are the liehous, and the four are the cavalry captains. Sima Yi Taoguang was obscure and vigorously refused to let his children become officials.
