I've watched a lot of Danmei, and it's very much like writing one myself. I just figured out the key to a rogue gangster becoming an emperor:
Only with Xiao He can there be Liu Bang, the great ancestor of the Han Dynasty, so hey~~~~
This can be regarded as a story written for myself!
This is my first time writing, it would be nice if someone could support me~~~
PS: Don't talk to me about historical issues! It's just a novel, don't take it seriously.
