What is Chen's grandfather?

Chen's grandfather realized that he was about to have a big disaster, so he fled the army with the help of his friends. Chen's grandfather is a fortune teller. He can easily calculate the future fate of an army, so he got the leader's fancy, but he didn't expect that his clever plan hindered the interests of some powerful people, so these people decided to kill Chen's grandfather under discussion and cleared the way completely.

However, I didn't expect Chen's grandfather to count not only Feng Shui, but also his own destiny. The night before these people tried to harm him, he had already calculated something bad, and he might have a catastrophe. So he took advantage of the opportunity that those people had not started work, discussed it with his friends and ran out of the army.

By chance, he met the leader of another army, entered another army, and watched this army rise and win, so he could finally restore his original identity and live a wandering life. But before that, in fact, someone recognized his identity, but it was not exposed.

Chen's grandfather is a very clever man. He knew that his fortune-telling skills would be envied by others, so when he entered a new environment, he chose to hide his sharpness. Not only did I not give advice to the leader, but I also didn't tell others my skills, so I lived in this army until the end.
