In a future where humanity has conquered the galaxy and martial arts have evolved alongside technology, Mokjin, the Heavenly Demon, awakens from a 2,000-year slumber on a radioactive Earth. He finds a world vastly different from the one he knew, where internal energy is generated by implanted Q-Drives and martial arts techniques are downloaded directly into the brain. Disgusted by this reliance on technology and clinging to the traditional ways of internal energy cultivation, Mokjin sets out to prove to the universe that its martial arts have gone astray. His journey begins with a chance encounter with the Nachal bounty hunting crew, who unwittingly become entangled in his quest. As Mokjin navigates this strange new world, he clashes with modern martial artists, encounters long-lost sects that have evolved in unexpected ways, and grapples with the implications of advanced technology on the very essence of martial arts. From battling hordes of technologically enhanced zombies to facing down powerful factions and even the Human Government itself, Mokjin’s unwavering belief in the traditional path of martial arts will be tested as he strives to reclaim his title as the greatest under heaven, now in a universe far beyond his wildest imaginings.
