Wei Shuhu transmigrates as Wei Zheng's youngest son, and he also has a Villain System.
The System: Host, go do bad things.
Wei Shuhu: Do bad things right under Li Shimin's nose?
But the System forces him to do it, so Wei Shuhu can only grit his teeth and get on with it.
At thirteen, he destroys his own home.
Li Shimin: What do you mean, you're making elixirs?
At fifteen, he sells illicit salt.
Li Shimin: What do you mean, you extracted this refined salt yourself?
At sixteen, he kills countless people.
The Turks: Give us back our khagan's life!
At eighteen, he destroys kingdoms, and there are more small countries in the Western Regions than he can count on one hand.
The kingdoms of the Western Regions: ???
The System's evaluation: Host, you truly are a once-in-a-century villain!
