I Open a Martial Arts Gym in Marvel and All My Students Are Superheroes

Lin Chen traveled through Marvel, just before the birth of Iron Man in 2008, and was bound to the all-around Japanese comic training system. Others rely on technology, mutation, and godhood, but he directly opened a martial arts gym in Hell's Kitchen: Teach the Six Styles of One Piece, Naruto Chakra, Hunter's telekinesis, Dragon Ball's energy, Fullmetal Alchemy... System: Recruit a superhero as a disciple and unlock invincible combat power!
