In his previous life, He Mo was a legend in the world of sports, but on the night of his greatest triumph, a mysterious demon possessed him, ruining his reputation and bringing about his tragic downfall. Reborn, he returns to the college sporting arena where his fate changed, with a remnant of the demon's origin inside him: "Demon Life." By absorbing his opponents' negative emotions, he can gain greater strength, speed, and perception, but he must also suppress the demonic nature threatening to consume him and turn him into a monster.

On the track, he smashes his opponent's cheating artifact and uses his own body to challenge the limits of the extraordinary. Demons see him as a thorn in their side, and shadowy corporate powers treat him as prey, yet the door to the national team quietly opens for him. Under the spotlight, he will shatter the schemes of every demon and god in the most incredible way imaginable. When the Demon Life inside him awakens to its ninth level, the truth behind his downfall in his previous life finally comes to light...
