Yu Zhou was instilled in "ancient (male protagonist) culture" by his sister since he was a child, so he slowly became interested in "ancient (villain) culture".
After growing up, Yu Zhou used various means to find the book-traveling department and asked them to send him to ancient times to experience the life of a villain.
Under Yu Zhou's bitter (wei) bitter (bi) begging (li) (you), the book reading department had to send Yu Zhou to an ancient novel.
With the "help" of the system, Yu Zhou began to act as a villain (without harming the people). He wanted to see if the villain's ending was as miserable as his sister said.
When the villain was about to leave, Yu Zhou began a new round of seeking death, saying "I want to seek power and usurp the throne."
"The Prime Minister wants to seek power and usurp the throne? Doesn't he just want to sit on the dragon's chair and sleep on the dragon's bed? I will satisfy him."
Yu Zhou overheard: "It seems that what my sister said is wrong. I'm about to turn over and become the protagonist."
At night, on the dragon bed, Yu Zhou said: "Sister is right, being a villain will not end well. ... Well, if you let me go back, I don't want to sleep on the dragon bed anymore."
Intention: You protect me for a while, and I will repay you for the rest of my life.
