Dream of the Three Kingdoms: Am I Becoming the Emperor of Qin?

[Do not destroy the original work + Not invincible + Slow pace] My name is Ying Zheng. Yes, it's what you think. I have the same name as Qin Shihuang. Of course, now is not the time to complain about names. Just now I came to another world, and a girl named Li Si invited me to participate in the dream battle? In fact, I refused at first, but I awakened the "system" Then I have to participate now Although I still don't know what the dream battle is exactly... Eh? There seems to be someone in front of me, go take a look... Liu Bei, who has transformed into Guan Yu, and He Jin, who has transformed into Wang Kuang, are fighting? How could I have such a dream?
