Supernatural: Fusion of Zuo Qianhu at the Beginning

Zuo Yu traveled through time. This world was similar to his original world in the 1920s, except that warlords were fighting in this world and demons were rampant. Fortunately, with the support of the system, Zuo Yu merged with the strongest Zuo Qianhu in the beginning. It's just that the fusion is too perfect, and it seems to have some side effects. So, whenever the system proposes a choice reward, Zuo Yu decided to beat the system hard first. Moreover, the demons in this world can also strategize!
