I Open a Martial Arts Gym in Chinatown

Lin Yi woke up and traveled through San Francisco in 1985. The martial arts school he inherited has gone bankrupt, and he lives with his junior sister who became an orphan at the same time. "Both parents are dead, but my sister has a house." "Why can't I be happy when I was twice as happy?" This is a world where combat power is clearly off track: a fighting madman who slashes and stabs tanks with his sword; an ancient swordsman genius who can match one to a hundred; a martial arts master whose combat power is maxed out. "Sure enough, hesitation leads to defeat." "After using the system method, everything is so perfect." "Fight! Boy."
