Protagonist: Modern Identity: Zhang Wei (an extremely ordinary, somewhat clever, good at lying down, proficient in Internet memes, fishing in the workplace, very eloquent but always a bit unlucky social animal/sales/customer service/programmer, etc.).
Ancient identity: Li Yaozu (also known as Xianyu) - the second son of the top nobleman of the Dayin Dynasty, "Dingguo Gong", and a well-known dandy in the capital. The original owner was arrogant and domineering, ignorant and unskilled, bullying men and women (but he may not have actually done it many times, more because of his reputation), his body was hollowed out by wine and sex, and in a conflict about "robbing a civilian girl" (actually a misunderstanding), he was soul-pierced by the protagonist.
Protagonist's personality: Extremely afraid of death (faced being chased by the master/family punishment/revenge of enemies as soon as he came in), (dream is to lie down and count money), talkative MAX (modern jokes, fallacies, first-class sophistry skills), assess the situation (quick to be intimidated, but does not hesitate when it's time to hug someone), petty citizen thinking (calculating carefully, being greedy for petty gains, loving money but getting it wisely - his way).
Cute contrast: wearing the shell of a bully and a playboy, doing cowardly things. I want to live a low-key life, but I am always forced to keep a high profile due to saucy tricks. He wanted to be a salty fish, but fate always pushed him to the forefront.
Goldfinger: No! It relies purely on modern knowledge (misunderstood), cool operation, hugging thighs, accidental collisions and a mouth that can make the dead alive (or angry). The only advantage: knowing some major historical events (but may misremember or misunderstand) and basic scientific common sense (but cannot make guns or cannons).
