I Built the Qin Empire!

In 250 BC, Lu Yu traveled through the Kingdom of Wei, but Lu Yu did not want to hang out in the Kingdom of Wei and decided to abandon Wei and join Qin. On the road, he happened to meet Ying Zheng who was returning to Qin from Handan, so Lu Yu assisted Ying Zheng like a son. Ying Zheng: "Sir, can Qin rule the world?" Cheng Xi: "If our Korean clan has Lu Yu to help us, why worry about not being able to destroy Ying Zheng?" Li Mu: "How could you trick King Zhao into killing me? What a trick, Lu Yu!" Jing Ke: "Assassinating Qin will definitely make me famous all over the world, and I, Jing Ke, will also leave a name for future generations! Damn it, where is the dagger in my map?" Ying Yinman: "Sir, will you teach me how to play the piano today?" … Lu Yu: "I just want to hang out as a guest. Why did Ying Zheng go to Rome? In this case, Ying Zheng, you should work harder and strive to unify the weights and measures of the earth." This novel and its characters are purely fictitious.
