Book 8 of Xishan Gourd

Qin Taichu traveled to the prehistoric world due to a car accident and obtained the Thief System. At the beginning, he stole the Dao consciousness of Pangu who wanted to kill Pangu, and obtained the Dao Saint cultivation. Pangu entrusted Honghuang to master the way of heaven, and was named the Taichu Saint. Just when he thought he was invincible, the system suddenly evolved and brought the prehistoric world into the world. However, he found that his strength was at most the same level as the mid-level prehistoric quasi-sage.
