Human War: I Have Guarded the Human Race for Tens of Thousands of Years

I have been in seclusion for thousands of years, and I heard that the human race is weak. I remember the time when the human race was prosperous. "There is no great emperor in the human race, and all races are guarding and fighting from all directions." The disappearance of the three major guards and the confusing problems made Li Yu fall into deep thought. As the human race's guardian envoy, Li Yu must shoulder the important task of conquering all directions. "What? The gods want to be enemies with my human race? I will take their king's head first" "The Demonic Dragon Clan wants to be friends with my human race? No, they are too ugly." "The four beast tribes want to force my human race to submit again? Let him come, I won't kill them" In a turbulent era, Li Yu started his own path to invincibility. I have nothing to do. Today I will teach some of the strongest people in the human race some exercises... This novel and its characters are purely fictitious.
