(Double male protagonists)
Su Wen, the "waste" second son of the Zhenbei Hou Mansion, had been a mediocre senior brother in the Immortal Sect for ten years. Everyone thought that he had mixed spiritual roots and had no hope of success in this life. No one knows that he has already practiced the five ways of talismans, formations, elixirs, weapons, and swords, just to find a perfect way in this man-eating world of immortality.
During a sect trial, Su Wen accidentally picked up a silly boy from the ruins of a massacre by demons. This child is so powerful that it doesn't hurt when he's beaten, and he won't die no matter how hard he tries, but his brain isn't working very well, and his only obsession is to fill his stomach.
Su Wen: "Silly boy, hang out with me from now on and call me senior brother. I will take care of your food." From then on, he had a junior brother named Wang Changsheng.
While the genius of the sect was still fighting for a single pill, Su Wen silently fed his junior brother a terrifying appetite comparable to that of a mythical beast. While the major forces were still wary of the demon clan's ferocious power, Su Wen had already commanded his invincible junior brother to smash every enemy into powder. He originally wanted to train his junior brother to be the strongest human shield, while he could safely be the sixth child behind the scenes. But he gradually discovered that this immortal junior brother seemed to hide a huge secret that shook the entire world.
