Garion was once a famous fitness influencer and a body scientist, and now,he was reincarnated in this mana cultivation world. Just like other novel MCs, he also got his own system, [God Gym]. The system was simple. Every person who trained in his gym would give him power. The more people trained, the stronger he became. Many cultivators called him a heretic just because of the weird workouts he did, but he didn't even care. Because, once his gym members started crushing those arrogant sects... nobody would be laughing anymore.
