Transmigrated to the Three Kingdoms! The System Makes Me Unite the Realm

After getting electrocuted while washing a car, Li Yun passes out as the System binds to him. His soul transmigrates to the Three Kingdoms world and enters Lü Bu's body. The System tells Li Yun that he must unite the realm to return to the real world. Seize Xiaopei, kill the three Liu, Guan, and Zhang brothers, drive Cao Cao into retreat, then send the iron cavalry straight to Yangzhou to destroy Yuan Shu. Cao Cao: Impossible! How does Li Yun have so many soldiers? Could they be heavenly troops sent down from above? Li Yun: Do you think I can tell you I have a System? Of course not. See how Li Yun uses the System to unite the realm in the Three Kingdoms.
