On the eve of the Investiture of the Gods calamity, among the Black Tortoise clan of the North Sea, the protagonist transmigrates into the body of Xiong Dabao, the clan's most doted-on young master. He has also acquired the legendary "Hundredfold Heaven-Devouring Physique": he can consume a hundred times the resources and not even make a sound, yet for fifteen years he has been stuck at the peak of Qi Refining. Even more absurdly, he has bound himself to a "money-grubbing" Heaven-Chosen Demon Traitor System.
With the Heaven-Chosen Demon Traitor System and his memories from before transmigrating, Xiong Dabao secretly manipulates the North Sea rebels and the Shang army into fighting each other, profiting from both sides and gathering massive resources. He successfully advances to Earth Immortal. After the war, Xiong Dabao follows the army to Chaoge, using his knowledge of the future to snatch opportunities, extort powerful ministers, and fleece both the Chan and Jie Sects. When the Investiture of the Gods calamity erupts in full, Xiong Dabao again profits from both sides, playing the Chan and Jie Sects, as well as the Shang and Zhou armies, against each other.
During the decisive Battle of Muye, his younger brother, Xiaobao, burns up his true spirit to take a fatal blow for Dabao. Xiaobao is reduced to nothing, and Dabao's Dao heart shatters. Through grief, he reforges himself and attains the Dao, becoming a Limitless Grand Supreme Golden Immortal. He reaches into the river of time and space to retrieve a remnant of Xiaobao's true spirit and brings him back to life. At that very moment, he hears his mother from before he transmigrated saying, "Master, now that this salvation ritual is over, will my son be able to have a smooth reincarnation?"
