Shangyong City is surrounded by water on three sides, and Meng Da set up a wooden fence outside the city to strengthen the city defense. Sima Yi waved his army across the water, destroyed its wooden fence, and approached the city.

In the first month of the second year of Taihe (228), Sima Yi's soldiers attacked the city in eight ways, and only 16 days later, Meng Da's nephew Deng Xian and his general Li Fu surrendered.

The Wei army entered the city, captured Meng Da, passed the first Beijing division, and captured more than 10,000 people.

Sima Yi returned to the army and was still stationed in Wancheng, rewarding and persuading farmers and prohibiting waste. The people of the south are happy and convinced.

At first, Shen Yijiu was in Weixing County, tyrannical power, and engraved a seal letter in the name of the emperor without authorization, and granted it privately. After Meng Da was killed, Shen Yi had doubts. At that time, the county guards saw that Sima Yi had defeated the enemy, and they all congratulated him. Sima Yi let it go, and let people hint to Shen Yi.

Shen Yi had no choice but to come to congratulate. Sima Yi took the opportunity to arrest him and send him to Beijing. Sima Yi also moved more than 7,000 families of Meng Da Yu to Youzhou. Soon, Shu generals Yao Jing and Zheng He led more than 7,000 of their subordinates to surrender.

Among them, there is Meng Da's wife's sister Zhang, Sima Yi wanted to accept and give up, but soon after morning sickness, Zhong Da stayed. In other words, Sima Yi originally wanted to bring Meng Da's sister-in-law over to have fun, but later found out that she had a pregnancy reaction and vomited, so she stayed.

At that time, there were many wars and countless killings, and everyone was looking forward to giving birth and had a sense of reverence for it.

…… ……

At that time, the border county was newly attached, and the household registration was false. The imperial court wanted to verify it, so it asked Sima Yi to go to Beijing and ask for his opinion. Sima Yi believed, "The thief was bound by a dense net, so he abandoned it." If you use the outline, you will be naturally happy."

Emperor Wei Ming asked him again that Wu Shu should be crusaded, where should he start first?

Sima Yi replied: "Wu Yi China is not accustomed to water warfare, so he dares to scatter in Dongguan. Whoever attacks the enemy will choke his throat (chō).

g) its heart. Xiakou, Dongguan, the heart of a thief. If the army is to Anhui City, lead the power to the east, and the water war army to Xiakou, take advantage of its weakness and attack it, this divine soldier will fall from the sky, and it will be broken. ”

Emperor Wei Ming agreed with him and ordered him to return to Wancheng to prepare for war. In August, the great Sima Cao Xiu did not follow the plan, and went down to Anhui City to go deep into the enemy territory to meet the Wu general Zhou Yi, who had surrendered fraudulently, and was ambushed by Lu Xun in Shiting, defeated, and Cao Xiu died of illness.

…… ……

In the third year of Taihe (229), Zhuge Liang, the prime minister of Shu, sent troops to attack Wei for the third time, and occupied the two counties of Wudu and Yinping.

In the following year, Emperor Wei Ming decided to rejuvenate Shu. Promoted Sima Yi to be the general, increased the governor, fake Huang Yue, and cut down Shu with the great Sima Cao Zhen.

In August, Emperor Wei Ming ordered Cao Zhen to lead the main force from Chang'an into the Meridian Valley, the left general Zhang He out of the Slope Valley, Sima Yi from Jingzhou back to the Han River out of the West City, and the generals divided into three ways to attack Hanzhong. Sima Yi opened up the road from Xicheng, advanced by land and water, went up the river along the water, went straight to Quren, conquered Xinfeng County, garrisoned Dankou, and then encountered the rain class.

In February of the fifth year of Taihe (231), Zhuge Liang, the prime minister of Shu Han, led the fourth army to attack Wei, surrounded Qishan Jia Si and Wei Pingbu, and transported grain and grass with wooden oxen and flowing horses. Emperor Wei Ming said to Sima Yi, "If there is something in the west, there is nothing to do with it", and sent him to the west to garrison Chang'an, and the governor of the left general Zhang He, Yongzhou assassin Guo Huai and others to defend the Shu army.

Sima Yi's generals Fei Yao and Dai Ling led 4,000 people to guard Guī, and led the main force west to rescue Qishan. Zhang He persuaded Sima Yi to divide his troops to garrison Yong and Yi in order to be the rear town of the army, but Sima Yi disagreed, he said: "It is expected that the former army can only deserve it, and the general will say yes; If it can't be, but is divided into front and back, the three armies of Chu are therefore black cloth birds. ”

So he advanced to Yu Elk and fought against Zhuge Liang.

…… ……

After the Shu army retreated, the military division Du Xi and the overseer Xue Yi both expected Zhuge Liang to invade when the wheat was ripe in the second year, and suggested that he should take advantage of the winter to transfer grain and grass to solve the problem of lack of grain in Longyou.

Sima Yi believed: "Zhuge Liang went out of Qishan twice and attacked Chencang once, but he was frustrated and returned. Even if he will send troops in the future, he will no longer attack the city, but seek a field battle, and the location will be in Longdong, not in the west. Zhuge Liang often hates the lack of food, and after he goes back, he will inevitably accumulate grain and grass, and I estimate that he will not send troops after three years. ”

In February of the second year of Qinglong (234), Zhuge Liang led an army of 100,000 out of the valley to attack Wei. In April, Zhuge Liang went to Méi County and stationed in the south of Weishui. Sima Yi led the army to cross the Weishui River and built a fortress against the water.

The generals wanted to hold Zhuge Liang across the water in Weibei, Sima Yi said: "The grain and property accumulated by the people are all in Weinan, which is a place to fight." ”

Then he crossed the Weibei water and camped.

At that time, Sima Yi was stationed in Weinan. Guo Huai estimated that Zhuge Liang would definitely fight for the Northern Plains, advocating the occupation first, he said: "If Zhuge Liang crosses the Weishui River and ascends the Northern Plains, he can join the troops of the North Mountain, cut off the Longdao, and frighten the subjects and the Hu people, which is a great danger to the safety of the country." ”

Many people disagreed, but Sima Yi agreed very much and asked Guo Huai to join the Beiyuan.

The camp has not been repaired, the Shu army pressed the border, and the Wei army fought back. Soon, Zhuge Liang led a large army to the west, and all the generals thought that Zhuge Liang wanted to attack the western siege. Guo Huai believed that Zhuge Liang's bluff was to make the Wei army respond aggressively, and his goal was Yangsui.

At night, the Shu army really attacked Yangsui, but Zhuge Liang failed to succeed because the city had already been prepared.

The record of the Book of Jin is roughly the same: "Sima Yi sent Hu Zun and Guo Huai to prepare Yang Sui, and Liang met in Jishi, fought in the plain, Liang could not enter, and returned to Wuzhang Plain." After sending strange soldiers to shine brightly, more than 500 levels were killed, more than 1,000 people were born, and more than 600 people were surrendered."

…… ……

In May, 100,000 Wu troops attacked Wei and fought with the Shu Han army, but were rejected by Manchu. In July, Emperor Wei Ming led his troops to recruit in person, and the Wu army withdrew.

The ministers thought that Sima Yizheng was still confronting Zhuge Liang's heavy troops in the west, and the car could drive to Chang'an, and Emperor Wei Ming said: "The right to go, the courage to break, the general to control it, I don't have to worry about it." ”

Zhuge Liang's eastward march was blocked by Sima Yi, and he advanced from Weishui, but Guo Huai blocked it, so he moved his army to capture Sanguan, Longcheng and other places, and returned to attack Sima Yi.

In August, Sima Yi held on to Zhuge Liang for more than 100 days with the instruction of "refusing to defend the wall and waiting for work at ease". Zhuge Liang challenged several times, but Sima Yi did not come out of the wall to wait for changes.

Zhuge Liang sent someone to Sima Yi to send the "Ornament of a Woman", wanting to provoke Sima Yi to fight, but Sima Yi still did not fight. In order to appease the dissatisfaction of his subordinates, he deliberately pretended to be angry and asked for war.

Emperor Wei Ming did not allow it, and sent the retainer of the bone fish, Xin Bi (pí), to be Sima Yi's military advisor to control his actions. As soon as Zhuge Liang came to challenge, Sima Yi was going to lead the troops to attack, and the Xinbi Staff Festival stood at the military gate, and Sima Yi did not send troops.

Shu general Jiang Wei said to Zhuge Liang: "The Xinbi Staff Festival is coming, and the thief will not come back." ”

Zhuge Liang said: "He has no war situation, so he insists on inviting fighters to show his strength." In the army, the king's order is not subject to it, and if you can control me, how can you fight evil for thousands of miles! ”

Zhuge Liang then divided his troops into tuntian and made preparations for a long-term cantonment.
