Immortality Is Prosperous

Chenxing Zhongdeng fell asleep in a different world in the feudal era and became a glorious time traveler. In a society still in the age of weapons, he managed to become a member of the official family by relying on the ancient martial arts he learned back then. They say this is the age of the end of the Dharma, but it has nothing to do with me cultivating immortality. I can just practice how I want to. Why do you need to be a copywriter? How deep your brain can be to be a small copywriter. Wouldn't it be better if I just copy modern history?
