Don't Hold On! My Lord, Your Fascia Is Stiff.

A modern sports rehabilitator is dressed as an orphan who died of illness in ancient times. He does not rely on medical skills or engage in national fitness. He only relies on a pair of eyes that can see through physical strain. He specializes in treating the regent who has been struggling for half his life and is covered with hidden injuries. He also uses the flaws in his muscles and bones to expose the disguise and conspiracy of the civil and military officials of the Manchu Dynasty.
