Sima Yi studied Zhuge Liang and left a plan before his death, which no one has been able to understand so far
Introduction: During the Three Kingdoms period, the princes of all sides were not only a confrontation between national strength and military strength, but also a strategic competition between the courtiers. During the Battle of Guandu, Yuan Shao's power was weak, and Guo Jia helped Cao Cao formulate "ten victories and ten defeats" and successfully helped Cao Cao annihilate Yuan Shao's troops. During the Battle of Chibi, Cao Cao was powerful, and Zhuge Liangqiao borrowed the East Wind and then burned Cao Cao's elite with a single fire, thus laying the pattern of three divisions of the world. Sima Yi, the heavy minister of Cao Wei, was not inferior to Zhuge Liang, and he left a strategy that remains unsolvable.
Sima Yi was born in a famous and prestigious family in Hedong, his ancestors were once high-ranking officials in the Western Han Dynasty, and his father was Luoyang Ling of that era, and local officials always recommended him as an official, but Sima Yi did not want to enter the army and preferred to study at home. Cao Cao accidentally learned of Sima Yi's fame, so he recruited Sima Yi to take up his post as a chancellor, but Sima Yi pretended to be ill and refused. Sima Yi's careful thinking naturally concealed Cao Cao, and Cao Cao did not break it, first arranging for assassins to go to his palace to find out the truth, and then threatening the political future of their Sima family. Sima Yi knew that he could not conceal Cao Cao and hurried to his post.
It turned out that Cao Cao did not know whether to choose Cao Pi or Cao Zhi as the heir, so he let Cao Pi and Cao Zhi compete on their own, and let Yang Xiu be Cao Zhi's aide and Sima Yi be Cao Pi's staff. Cao Pi asked Sima Yi how to ascend to the throne, and Sima Yi believed that the world was not yet at peace, and only needed more military merits, and to make good friends with the generals in the army, with honor and the support of the generals, the position of heir was within reach. Cao Pi followed Sima Yi's ideas and plans, and was indeed made the heir by Cao Cao. After Cao Cao's death, Cao Pi established himself on his own behalf, and Sima Yi soon became the leader of Wen Chen.
Cao Pi died within a few years of his ascension to the throne, and before his death, he made Sima Yi an auxiliary chancellor and asked him to assist the Wei Ming Emperor Cao Rui. When Zhuge Liang heard of Cao Pi's death, he took advantage of the political turmoil in Cao Wei to begin the Northern Expedition, and Cao Wei Yongliang was in a hurry, and many places were taken by Zhuge Liang. Emperor Wei Ming thought for a moment and then sent Sima Yi to the front to command the troops, and Sima Yi's sphere of influence also stepped from the political arena into the military circles, and established his prestige through many confrontations with Zhuge Liang. When Zhuge Liang fell ill and died in Wuzhangyuan, Sima Yi also returned triumphantly with great merits, and after the death of Emperor Ming of Wei, no one could suppress Sima Yi, and Cao Wei's power was also taken away by Sima Yi.
In the ten years that Sima Yi and Zhuge Liang fought, although the two were opponents, he was good at learning and learned a lot from Zhuge Liang. He knew that zhuge liang's death was suspicious of the old army, the purpose was to make the world not know where he was buried, and before sima Yi died, he ordered: "In Shouyang Mountain, it is a soil treasure, and there is no grave or tree; as a three-part article of care for the order, it is timely to serve, there is no bright instrument, and those who are finally buried together." "It means to be buried in Shouyang Mountain, don't plant trees, don't erect graves, and don't use valuable things to accompany the burial." It is precisely because of this arrangement that no one in the world knows where Sima Yi's tomb is buried, and no one can understand it to this day.

Conclusion: We don't know if Sima Yi thought that when he was young, he would sit in the world in a few decades, but it can also be seen from his resume that as long as he has the ability, he will have a head start. Moreover, in the era of the Three Kingdoms with the warrior clan as the core, everyone first considered the interests of their own families, followed by other interests, and Sima Yi's approach was in line with the phenomenon of that era.
