Introduction: Chu Feng, a social animal, saves people from death. His soul travels through the world of tomb robbers and awakens the god-level Gu system. Everything can be refined into Gu, such as immortality, parasitism, vajra, rejuvenation... With thousands of kinds of Gu hidden in the body, one can control life and death, and control yin and yang. In order to find strange materials for refining Gu, he teamed up with Hu Bayi, Fatty Wang, and Shirley Yang to go through the Longling Labyrinth to refine Corpse Gu, explore the Yunnan Worm Valley to cultivate exotic Gu, and enter the Kunlun Temple to seize the Immortality Gu. Deep in the ancient tomb, if Zongzi gets in the way, he uses poisonous insects to eat him, and if there are dense traps, he uses poisonous techniques to break them. Let's see how he uses his poisonous techniques to defy the sky, and climbs step by step on the road of a near-death struggle, and becomes the legend of immortality!
