After Cao Zhen withdrew from the army, Liu Du did not take the opportunity to march, he knew that there were Cao Pi and Sima Yi behind him, and it was difficult to conquer the territory of Wei at this time. He was gambling, betting that Cao Pi was as short-lived as in history, and died after a few years in power.

After Cao Pi withdrew from the army, he ordered Xu Huang to stay in Yuzhou, Zhang He to guard Nanyang, and strictly guard Liu Du. Cao Pi's attack on Liu Du was unfavorable, and he was depressed all day long. Yu Ban learned that Cao Pi was like this, and Shangshu asked Ying to be the general to crusade against Liu Du for Cao Pi, but Cao Pi ignored him.

Let's say that Cao Pi and Zhen Mi have a son, named Cao Rui, the character Yuanzhong, who has been smart since childhood, and Cao Pi loves him very much. Later, Cao Pi accepted the daughter of Guo Yong, a member of Guangzong in Anping, as a noble concubine, so Mrs. Zhen fell out of favor.

At this time, Cao Pi suffered from tuberculosis again, and the medical skills of this era were not good. Guo Guifei Xingchen Zhang Tao fraudulently claimed that he had dug up a puppet full of needles in Mrs. Zhen's palace.

Cao Pi was furious, thinking that Zhen Mi was cursing himself, so he gave Mrs. Zhen to death and made Guo Guifei the queen. Guo Guifei has no son, and raised Cao Cao Rui as a son, although she loves him very much, she does not establish herself as an heir.

When Cao Rui was fifteen years old, he was skilled in arching horses. In the spring and February of that year, Cao Pi took Cao Rui out hunting. When he came to the mountain dock, he drove out a doe and a fawn, Cao Pi shot down the doe with an arrow, and turned around to see the fawn running to Cao Rui's horse.

Cao Pi shouted: "Why don't you shoot it? ”

Cao Rui cried on the horse and said: "Your Majesty has killed his mother, and the minister has forbearance to kill his son." ”

After Cao Pi heard this, he threw the bow on the ground and gritted his teeth and said to Cao Pi: "My son is really the lord of benevolence and virtue!" So Cao Rui was named the king of the plains.

In the summer of May, Cao Pi was infected with a cold disease again, and he could not be cured for a long time, so he summoned Cao Zhen, Jia Kui, and Sima Yi to the dormitory. Cao Pi summoned Cao Rui to come, pointed to Cao Zhen and the others and said, "Now I am seriously ill and cannot be resurrected. This son is young, and the three of them can be good at assisting him, so don't be disappointed. ”

All three of them prostrate on the ground and said, "Why did Your Majesty say this? The ministers are willing to do their best to serve Your Majesty, and live long live. ”

Cao Pi waved his hand and said: "This year, the Xuchang city gate collapsed for no reason, which is a bad omen, and I know that I will die." ”

While he was talking, Cao Xiu, the general of the Eastern Army, entered the palace to greet him. Cao Pi summoned Cao Xiu in and said to them: "The country is in a critical period of survival. Qing and others are all ministers of the country's pillars, if they can work together to assist my son, they can protect my Great Wei Sheji! ”

After Cao Pi finished speaking, he burst into tears. So Cao Zhen, Jia Kui, Sima Yi, Cao Xiu, etc., mourned on the one hand, and supported Cao Rui as the emperor of the Great Wei Dynasty on the other. Cao Rui's father Cao Pi was Emperor Wen, and his mother Zhen was Empress Wenzhao. Feng Cao Zhen is the general, Cao Xiu is the great Sima, Wang Lang is the Situ, and Sima Yi is the hussar general. The rest of the civil and military bureaucrats were given their own gifts and amnesty to the world. At this time, Yong and Liang were short of guards, and Sima Yi begged to guard Xiliang and other places. Cao Rui then appointed Sima Yi to supervise the soldiers and horses in Yong, Liang and other places.

There was already a detailed report to Sichuan, and Zhuge Liang was shocked: "Cao Pi is dead, and his son Cao Rui is on the throne." His Majesty is now stationed in Nanyang, and he will start the Northern Expedition in a few days. I have to be ordered by His Majesty to lead the Sichuan soldiers out of Qishan, Sima Yi has a deep strategy, now Du Yong, Liang soldiers and horses, if the training is completed, will want to cut down Shuzhong first, in order to contain Your Majesty. I might as well start with an army to attack them. ”

Ma Tan, who joined the army, hurriedly dissuaded: "There is emptiness in Shu today, and the prime minister is returning to the south, and the army and horses are tired, so it is only advisable to save the shirt, how can you resume the expedition?" There is a plan to make Sima Yi die at the hands of Cao Rui, I don't know if the prime minister agrees? ”

Zhuge Liang asked what the plan was, and Ma Jian smiled and said: "Although Sima Yi is the minister of Wei, Cao Rui and others are suspicious. Why don't you secretly send people to Luoyang, Yejun and other places to spread rumors, saying that this person wants to rebel. He also made Sima Yi's announcement to the world, and posted it everywhere, making Cao Rong suspicious, and he would definitely kill this person. ”

Zhuge Liang listened to Ma Tan's plan, and then sent someone to carry out this plan.

But it was said that on the door of a house in Yecheng, suddenly one day, the owner saw a notice posted in front of the door. The gatekeeper unveiled it and came to play Cao Rui. Cao Rui read the list article, which roughly said:

Sima Yi, the commander-in-chief of the hussar generals, Yong, Liang and other places, would like to announce to the world with faith: Emperor Taizu Wu in the past, founded the foundation, and originally wanted to establish Prince Chen Si as the head of the society; Unfortunately, treacherous and treacherous, the dragon has been hidden for a long time. The emperor's grandson, Cao Rui, has no virtue, arrogantly pretending, and has the will of the ancestors. Today, I should be obedient to the people of heaven and rejuvenate the teacher to comfort the hope of all the people. When the notice arrives, everyone should return to the new king. If you don't go along with it, you should destroy the nine tribes! I would like to know about this.

After reading it, Cao Rui immediately became suspicious of Sima Yi and asked the ministers urgently. Liu Fangqi, a regular attendant of the loose horseman, played: "Sima Yi begged for Yong and Liang on the table, and it was for this reason. In the early days, Emperor Taizu Wu said to his ministers: 'Sima Yi looks at the wolf and cannot pay for the power of the army; It will be a great disaster for the country for a long time. Today's anti-love has sprouted, and it can be punished quickly. ”

Situ Wang Lang played: "Sima Yi is well versed in strategy, good at military opportunities, and has great ambitions; If you don't get rid of it early, it will be a disaster for a long time. ”

Cao Rui then issued an edict and wanted to raise troops to conquer in person. Suddenly, the general Cao Zhen played in the squad department: "No." The first emperor entrusted a few people such as lonely ministers, and he knew that Sima Zhongda had no different ambitions. I don't know whether this is true or not, and I am forced to increase my troops. Or the Shu people are treacherous and conspiratorial, so that my monarch and ministers are in chaos, but he takes advantage of the weakness to attack, and it is not known. Your Majesty is glad to see it. ”

Cao Rui was still suspicious of Sima Yi: "If Sima Yi rebels, what will he do?" ”

Cao Zhen said: "If Your Majesty is suspicious, you can imitate Henkel's pseudo-cloud dream." The royal driver is fortunate to be in peace, and Sima Yi will inevitably come to greet him; Looking at its movements, it was caught in front of the car, but also. ”

Cao Rui obeyed Cao Zhen's plan, so he ordered Cao Zhen to supervise the country and personally lead the 100,000 Imperial Forest Army to Anyi.

Sima Yi didn't know why Cao Rui came suddenly, thinking that Cao Rui was here to review the new army, so he reorganized his troops and horses and led tens of thousands of soldiers to greet him.

The minister said: "Sima Yiguo led more than 100,000 troops to resist, but he was really anti-willing. ”

Cao Rui hurriedly ordered Cao Xiu to lead the troops to meet him first, and Sima Yi saw the soldiers and horses coming, thinking that Cao Rui's car drove here in person, and greeted him on the road.

Cao Xiu came out and shouted: "Zhong Da is entrusted by the first emperor, why is he anti-yes? ”

Sima Yi was shocked, sweating all over his body, and asked in surprise: "Why did Da Sima say this?" ”

Cao Xiu told Sima Yi everything before.

Sima Yi sighed and said: "This enemy country is plotting against each other, trying to make my monarch and ministers kill each other, but he takes advantage of the situation to attack. A certain person should see the Son of Heaven to distinguish it. ”

Sima Yi hurriedly retreated his military horse, and went to Cao Rui's car and knelt down and cried: "The minister is entrusted by the first emperor to be lonely, and he dares to have different intentions?" It must be Han Xuan and Liu Du's treacherous scheme. The ministers please mention the division of the first brigade, first break Liu Du, then attack Han Xuan, report to the first emperor and His Majesty, and show the hearts of the ministers. ”

Cao Rui's doubts are unresolved. Sun Zi, a close minister, said: "Don't pay Sima Yi military power. But they can go back to the field. ”

According to Sun Ziyan, Cao Rui reduced Sima Yi and returned to his hometown, and ordered Cao Xiu to be the governor of Yong and Liang. Cao Rui drove back to Luoyang.

But he said that he would investigate the matter and return to Sichuan to report. After Zhuge Liang heard this, he was overjoyed and said: "I want to destroy Wei for a long time, but there are Sima Yi Zongyong and Liang's soldiers." Now that the plan has been degraded, what worry do I have! Immediately send a message to Wuchang, show your majesty, and make an appointment to march at the same time. ”

The crown prince Liu Dan learned that Zhuge Liang was preparing for the Northern Expedition, and hurriedly came to stay: "The Prime Minister's southern expedition is difficult; Fang Shi returned to the capital and sat on the seat; Now I want to go north again, and I am afraid of exhaustion. ”

Zhuge Liang bowed and said: "The minister is entrusted by His Majesty, assists the country in governance, and has not been lazy all night." Now that the south has been peaceful, there is no need to worry about the future, and the army in front of His Majesty has been stationed for a long time, so why not beg for thieves at this time, but when? ”

So Zhuge Liang left Guo Youzhi, Dong Yun, Fei Yi and others as servants, and the general regent of the palace. and left Xiang Zhong as a general, the governor of the Imperial Forest Army; Jiang Wan joined the army; Zhang Yi is a long history and is in charge of the prime minister's affairs; Du Qiong is the counselor; Du Wei and Yang Hong are still scholars; Meng Guang and Lai Min are sacrificial wines; Yin Mo and Li Wei are doctors; Yin Zheng and Fei Shi are secretaries; Zhou is the history of Taishi. There are more than 100 civil and military bureaucrats inside and outside, and the same thing is done in Shu.

Zhuge Liang returned home and summoned the generals. Former Governor Zhenbei General, Linghanzhong Taishou, Duting Hou Pang De; The former military governor led the wind to guard Ma Dai too much; The rear army led the troops to make General An Han and Jianning Taishou Li Hui, and the deputy general General Dingyuan and Ling Hanzhong Taishou Lu Yi; Liu Yan, the general of the military division and the marquis of the capital; Ma Yan, General Anyuan of the Chinese Army; Wu Yi, the Marquis of Gaoyang, the general of the left; Commander Shi Suijun General Yang Yi; Liu Ba, a former general of Zhengnan; Xu Yun, the former general of the Protector Army and the Marquis of Seoul Pavilion; The left protector believes in the Zhonglang general Ding Xian; Liu Min, the general of the right guard; marched to join the army Zhaowu Zhonglang General Hu Ji; marched to join the army and counsel General Yan Yan; Du Yi, the general of the army, Du Qi, the general of Wu Luo, and the Wei Sheng of Suirong; engaged in martial arts general Fan Qi; Fan Jian, secretary of the Dianjun Army; Prime Minister Ling Shi Dongju; The left guard in front of the tent made Long Xiang General Guan Xing; The right guard made the tiger wing general Guan Ping.

The above officials all followed the Pingbei Metropolitan Governor, Prime Minister, Wuxiang Marquis, and Lingyizhou Mu Zhuge Liang to the Northern Expedition to Cao Wei.
