Traveling through the Zhenguan period of the Tang Dynasty, he found that he had become the substitute and shadow of the current prince. It's the kind of substitute who has to die on his behalf when he encounters danger.
He was unwilling to become a substitute, a shadow that could die for the prince at any time, so he relied on the system to kill the current prince, and then pretended to be the prince, using his identity to continue living in this world.
Protagonist: "If I kill you, I can replace your identity with a face exactly like yours and habits that are exactly like you, and continue to live."
Li Chengqin: "You treacherous traitor! You pretend to be of royal blood and actually try to steal the world!"
Protagonist: "From today on, you are the substitute Li Yi, and I am the crown prince Li Chengqin."
After saying that, he killed the current prince.
This is the story of a false prince who stole everything from the Tang Dynasty.
