Prehistoric: the First Disciple of Jiejiao, the First Immortal of the Human Race

Xu Wen died suddenly at work and traveled to the prehistoric world. The time happened to be when Nuwa was creating humans, and he became one of the three thousand innate human races. Thinking of the future catastrophe for the human race, Xu Wen scratched his head and head in worry. Fortunately, he has awakened the "Supreme Sign-in System". As long as he is next to famous people and famous places in the ancient world, he can sign in and receive generous rewards! In order not to die in the future catastrophe of the human race, and for the smooth reproduction of the human race, Xu Wen began to think about ways to break the situation. Finally, one day, Taiqing Laozi came to the human race to preach. Xu Wen failed to worship Taiqing Laozi as his teacher, so he chose to join the Jiejiao sect and became the first disciple of the Jiejiao sect, officially starting his journey of signing in! [Congratulations to the host for successfully signing in "Tai Qing Laozi" and obtaining the "Tai Qing Jade Book" and the Nine-turn Golden Elixir] [Congratulations to the host for successfully signing into "Yuanshi Tianzun" and obtaining "Jade Clear Jade Book" and Pangu Essence and Blood] Relying on constant check-ins, Xu Wen obtained a large amount of cultivation resources, and his cultivation reached the peak of the world. The demon tribe wants to slaughter the human race? Die for me all! Tiandao wants to plot against humanity and Jiejiao? Then I will destroy this heaven!
