Immortal Reborn As City’s King!

He was the strongest immortal in his world. Then he died, and woke up as a weak boy in a city full of enemies. They laughed at him. Called him useless. But when they crossed him, he didn’t fight back with fists. He healed their wounds… And broke their minds. Now every hospital fears his name. Every villain regrets challenging him. And the woman who once left him? She’s begging for one more chance.
