Xie Ansheng learned medical skills from Xiang Yelang for eighteen years. He is lustful, greedy for money, and afraid of death. His biggest wish is to take his adopted sister to open an expensive three-story medical clinic in Tiandu. But Tiandu is tens of thousands of miles away. The brother and sister could not afford the fare for the spirit boat, so they could only serve as the team's doctors on a giant mountain and sea beast that carried an entire trading town on its back across the black wasteland. On the seventh day after departure, the beast fell. Black rain falls from the sky, wild beasts smell the fishy smell, and hundreds of tourists are about to be trapped in the black wilderness. All the doctors said that the giant beast's life was over, but Xie Ansheng discovered that something had penetrated its lungs and was eating the living mountain from the inside. If he wants to survive, he must enter the giant beast and dig out the thing. Someone asked him if he was afraid. Xie Ansheng picked up the medicine box and glanced at the overly beautiful female swordsman next to him. "Afraid." "But the medical fee has been negotiated." "If you run away now, you have to refund the money."
From the heart of the black beast to the underwater city of memory, from the floating mountains of the Tianhe Sword Ruins to the ancestral bone battlefield of the Ten Thousand Beast Demon Kingdom - Xie Ansheng traversed eight kinds of mountain and sea wonderlands, using his diagnostic eyes to discover that the Immortal Way to Heaven is extracting the life of Kyushu from the source. He has no system, no divine body, no suddenly awakened bloodline, only body control, on-the-spot response, and precise judgment of human relationships that he has trained for eighteen years. When Jiuzong asked him to choose which area to sacrifice, when those who returned from outside the world asked Jiuzhou to continue their support, when the master advocated closed cultivation in exchange for safety - he had to propose an alternative path that everyone could verify, modify and choose, instead of becoming the new number one in the world. In the end, the person who had been clamoring for a refund became the only one who refused.
Intention: A traveling doctor who is afraid of death and greedy for money, operates on the body of a giant beast, and rebuilds the path of immortality in the ruins.
