Honghuang, My System Is Really Too Messy.

Li Yi traveled to the prehistoric world and became the disciple of the three emperors of the human race. Not long after the Yellow Emperor became enlightened, when the prehistoric world was relatively peaceful, the entire prehistoric world could travel! But every time when you are about to go out, the system will threaten you by saying that it is dangerous outside and it is better to blow yourself up than to be killed if you go out. Li Yi praised: "My system is so robust!" In this way, I survived the period of becoming a god until one day Li Yi: "I'm almost invincible. If you don't let me out, let's die together." Hey, it's detected that the host is more dangerous than outside, please let the host fly freely!
