I was once a legendary hunter, but a devastating accident left my body completely broken, my mana veins shattered, and my career ruined. Forced into retirement, I accepted my fate and focused entirely on basic physical therapy and rehabilitation just to walk again.

But my rehabilitation clinic wasn't ordinary, or maybe my body wasn't. Every time I stretched, did a painful repetition, or forced my broken muscles to heal, a strange hidden system notification popped up. It turns out, the repetitive, grueling recovery movements were perfectly matching the ancient, lost breathing techniques of the Dragon Clan. By simply trying to survive physical therapy, I accidentally awakened a dormant dragon heart, absorbing overwhelming cosmic mana with every single workout. Now, while the world thinks I'm a crippled, forgotten extra, I am casually building a body that can shatter mountains just by doing my morning stretches.
