My Soul Has Penetrated the Tang Dynasty, I Am Cheng Yaojin.

At the end of the Sui Dynasty, Cheng Yaojin wanted to live a peaceful life, but historical inertia forced him to rebel. If you rebel, just rebel. He deceived Li Shimin into a partner. This book is mainly light-hearted and humorous, supplemented by Machiavellian passion. Modern memes collide with the heroes of the Sui and Tang Dynasties, using "irregular" ways to do "serious" things.
