Prehistoric: the Invincible Demon King

Niu Kui felt very uneasy. Why do you feel this way? Because he is dead. He died trying to save people. What he didn't expect was that after his death, he would encounter a plot that only existed in novels, time travel. Moreover, his soul traveled through time. Traveled to the prehistoric world. God, if you say time travel, just do it. But at least you let me be a one-person head office, right? But even for such a small request, God did not satisfy him. Because he traveled through time and space into a demon clan. A cow to be exact. If you dig deeper. Niu Kui discovered that the body he occupied was really extraordinary. Because he is the famous Great Sage Pingtian and the Great Bull Demon King in later generations. But thinking about the fate of the Niu Demon King, Niu Kui couldn't help but feel a deep despair. Fortunately, he awakened the system at the critical moment. From then on, I, the Bull Demon King, embarked on a path of changing my life against the odds.
