Qin Chuan, a modern monk who failed to overcome the catastrophe, traveled through the wilderness with the analytical ability of the "Principle of All Things" (pseudo system) and realized that the human race is a "bug product" of heaven. When all the time-travelers were vying for Sanqing's thigh, he resolutely chose to become a disciple of Guang Chengzi, who had a "mediocre record" in Fengshen. Relying on modern scientific thinking to analyze the laws of the ancient world, he not only improved his own cultivation by leaps and bounds, but also began to "reversely cultivate" his master - improving the Yuqing Immortal Technique and transforming the Fantian Seal into the "Ancient Truth Cannon". When the catastrophe of becoming a god comes, in the face of the ridicule of the Tongtian leader, Qin Chuan and the new master and disciple Guang Chengzi will use the absolute power of "scientific cultivation of immortality" to shake the entire prehistoric era and completely rewrite the fate of "sending people's heads"!
