The Heavenly Demon, who died after a seven-day pursuit, possesses the body of a high school loser.
The absolute powerhouse of the Murim and the strongest under heaven, the Heavenly Demon. He held the world in his hands, but the heavens did not permit him to stand alone forever. The Murim Alliance mobilized all top-tier masters for a seven-day pursuit to subjugate him. The Heavenly Demon drove most of them to the brink of death with his overwhelming martial arts, but after an endless war of attrition, he suffered fatal wounds that were impossible to recover from. Ultimately, the Heavenly Demon met his end. However, the place where he opened his eyes was not the Murim, but 21st-century South Korea. The soul of the Heavenly Demon possesses the body of an ordinary student who was bullied at school and lived as a 'bread shuttle' for the school delinquents. At first, he thought it was a weak body, but upon closer inspection, it was a rare constitution close to the 'Heavenly Martial Body' mentioned in the Murim—the ultimate talent for learning martial arts. In the past, martial arts were real and countless masters existed, but as times changed, the development of modern firearms like guns and bombs provided far more efficient means of killing than martial arts. The Murim gradually faded into history, and martial arts were lost, passed down only as legends or absurd stories. People today do not believe in the existence of martial arts and do not even know they were real. The Heavenly Demon retains all the memories, enlightenment, and the realm of martial arts from his previous life. The only thing lacking is internal energy. He begins to train his martial arts again, adapting to the modern environment, and starts to grow strong in an instant. The school delinquents and their violence are nothing more than child's play to the Heavenly Demon. He will overturn the order of this era in his own way and aim to become the strongest under heaven once again, starting with the school.
