While studying a demon dragon that had massacred millions on a Federation colony planet, the chief medical officer—the only person in the Earth Federation on par with the Federation President—was sent back to the modern era due to the demon dragon's self-destruction using a secret technique. He became a second-generation rich kid so frail he could faint at any moment.

Back in the modern world, relying on unparalleled medical skills, he works to improve his own body while retraining his nine-level physique. But time is running out, and martial arts masters, even cultivators, and the invasion of alien civilizations loom ever closer...

Watch as our chief medical officer faces all of this and embarks on a path to break through his own limits.
