Legend has it that before Zhuge Liang died, he had already calculated that after his death, Sima Yi would come to dig his grave, so he built 72 fake tombs in various parts of Sichuan and Shu, and buried the heavenly books soaked in poison water in the graves. Why was Zhuge Liang afraid that Sima Yi would come to dig a grave? It turned out that they had fought countless battles on behalf of the armies of the two countries before.

Once, Zhuge Liang once burned the Gourd Valley, leaving Sima Yi's father and son trapped in the sea of fire, almost losing his life. Zhuge Liang sang about the empty city plan, which made Sima Yi very sad when he thought about it. The two armies faced each other, and Sima Yi suffered a lot, and at that time Sima Yi's scalp tingled as long as he heard Zhuge Liang's three words. He thought, Zhuge Liang, Zhuge Liang, if you let me get your Heavenly Book, you would have been a defeated general of my men, Sima Yi heard that Zhuge Liang was dead, and couldn't help but laugh out loud, but thinking about it, if Zhuge Liang's Heavenly Book fell into the hands of others, it would be bad, Sima Yi heard the spies say that Zhuge Liang buried the Heavenly Book into the grave, and also built 72 tombs, it was really angry and thunderous, he thought. 72 graves, that is not difficult for me, I have to find out the book of heaven. Whoa, whoa, Sima Yi ordered the soldiers to dig graves day and night, but 71 were dug, all of which were empty, and there was nothing in them. Sima Yi was not dead-hearted, and when he dug into the 72nd seat, he saw that there was a set of books inside, and Sima Yi was overjoyed and personally bent down to pick it up. A Sima Yi actually knelt down in front of Zhuge Liang's grave, oh, what is going on? You must know that the two of them are sworn enemies, it turns out that the iron absorbing stone was buried under the platform in front of the grave, and this iron absorbing stone firmly sucked Sima Yi's armor, so that he had to kneel in front of the grave, hey, hey, Hey, Sima Yi,
I couldn't care less about my own wretched look, so I quickly opened the Book of Heaven and looked at it, and opened the book, only to see that it said, "The Book of Heaven can't get it, send you to see Yan Luo." Sima Yi thought, Zhuge Liang, Zhuge Liang, you are already dead, do you still want to scare me? The Book of Heaven has fallen into my hands, and who in the world will be my opponent? He sneered and continued to flip back. A found that the final paper was actually glued together, Sima Yi licked the index finger of his right hand to see the words on the book, and Sima Yi's lungs were about to explode, and there were two lines on the book. Before he died, he could not capture Sima And after death, Sima was captured by me. Sima Yi thought, Zhuge Liang must not have wanted me to read his Heavenly Book, and only then did he come up with such a way to anger me, I can't hit his plan. He held his breath and turned the pages one by one. By the time the book reached its last page, it still saw nothing. Suddenly, he felt the sky spinning, and his head seemed to be about to crack. Sima Yi knew that the book must have been soaked in poison, he repeatedly used his tongue to lick his fingers to turn the pages, this side was poisoned, and it didn't take long for Sima Yi to spit white foam and fainted on the ground. After Sima Yi was awakened by someone with an antidote, he no longer went to look for the Heavenly Book. He knew that these 72 tombs were all fake graves, and there was no way to find the Book of Heaven. In order to commemorate Zhuge Liang, the descendants rebuilt the tomb in the place where he was buried, which is now the tomb of Wuhou under Dingjun Mountain.
