[Feel-good power fantasy + fast-paced + System + decisive and ruthless + unhinged protagonist + crazy antics + invincible + lone wolf + no female lead + status panel + leveling up + simulation]

As dynasties rise and fall, the Seventh Prince is poisoned to death while fighting for power.

Li Yunyi transmigrates into this world as the Seventh Prince, and his vision immediately goes black.

Driven into a corner, he discovers that the status editor from his previous life has come with him...

The System unlocks new skills one after another: immunity to negative effects, status transfer, effect reversal, cultivation technique comprehension, technique deduction...

From then on,

when others get thirsty, they drink water. When he's thirsty, he drinks poison.

When others carefully choose which cultivation techniques to learn, he only picks forbidden arts and secret techniques that could cripple or kill him.

When others see demons and monsters, they turn pale with fear. When he sees them, he throws his arms wide and cries, “Family!”

“You say cultivating this technique will leave me crippled? That's hilarious, pal. I'm not afraid of being crippled. I'm only afraid it won't kill me.”

“A curse? Hurry up, buddy, aim for my brain. That's my weak spot, so it'll work fast.”

“Spending money lets me speed up comprehension through simulations and even deduce new techniques? System, let me spend a hundred thousand!”

“Effects reversed, so taking a beating makes me stronger? Heh, hit me harder! What, were you not fed?”

At an ancient ruin:

“Fellow Daoist, don't be rash! This formation corrodes the soul. Fellow Daoist?! Why are you charging faster and faster?!”

“Fellow Daoist, don't touch those pills! There could be a trap! Wait, are you insane? Why are you swallowing them like they're a meal?!”

Time passed, and the years flew by. Only after Li Yunyi killed the Demon Lord with a single punch did he realize that he seemed to have become invincible…
