Sima Yi saw something engraved on a stone and shouted that Sima Jia was in danger.

Sima Yi picked up a stone on the road with four big characters written on it: Niu Jima and Hou.

Sima yi's hard-won world, he didn't have much time to enjoy, and he could only consider for his descendants. It is this world that should fall into the hands of people named Niu, which is naturally unacceptable to Sima Yi.

In fact, in ancient times, we still attached great importance to this strange thing. Finding that stone is an ominous sign. Even with the idea of believing, Sima Yi will not let go of such threats.
