He transmigrates to the Great Qin dynasty and becomes Li Si's son.
He accidentally activates a System: all he has to do is keep his head down until Great Qin falls, and he can become a sage!
That's it? So he can just lie flat?
But Li You never expected Ying Zheng to be able to hear his inner thoughts.
Ying Zheng: "The Son of Heaven of Zhou implemented the enfeoffment system and ruled for a hundred years. Great Qin should follow suit."
Li You: [Exactly, the enfeoffment system is great. Hurry up and implement it, so your princes and ministers can descend into chaos. Maybe it'll even hasten Great Qin's demise!]
Ying Zheng: "Zhao Gao has rendered meritorious service. Make him Director of the Secretariat."
Li You: [Brilliant! Before long, Zhao Gao will install Hu Hai as emperor, making him Qin Er Shi. Then Great Qin's fall will be just around the corner.]
Ying Zheng: "Xu Fu, take my decree and seek the elixir of immortality."
Li You: [Great. Hurry up and poison Brother Zheng, then flee with three thousand boys and girls!]
Ying Zheng: "..."
Looking at Li You, who was hiding in a corner and yawning, Ying Zheng said, "Li You, since you are so good at offering advice, from now on you will make decisions on my behalf!"
Li You: "??? What does this have to do with me?"
