Traveling Through Xu Damao, I Don't Want to Be a Homeless Person

The protagonist's identity has traveled through time, and he is no longer a "just" third party, but has traveled through time to become Xu Damao, one of the most famous "beasts" in the courtyard. Before time travel: A modern "soft persimmon" good old man who always thinks of others, but ends up being cheated by colleagues, friends, and relatives all his life. After time travel: Xu Damao, who became the most notorious person in the hospital, discovered that being a "villain" was so satisfying. He used Xu Damao's identity to fight evil with evil, and returned the methods of those who dared to bully "good old people" a thousand times back to the real beasts in the courtyard.
