Cao Cao Was Reborn, Cultivated Immortality, and Robbed Tombs

In 220 AD, Cao Cao, the great hero of the Three Kingdoms Dynasty, died. Seventy-two tombs were built during his lifetime. On the day of burial, four coffins were carried out from the four gates of Yecheng. They were not sealed or planted, and they were buried sparsely. So the world doesn't know where Cao Cao's tomb is. Cao Cao arranged all this just for rebirth. Cao Cao was reborn in the world of cultivation, stealing monks' tombs and cultivating immortality at the same time. Later, he met his old rival Sima Yi. How would the two confront each other in the world of cultivation?
