What's more important is that he has already died of terminal cancer once, and now that he has another chance to travel through time, he must enjoy life to the fullest no matter what. Just when Liu Zheng thought he could open a martial arts gym and enjoy life at the same time, he didn't expect that the world was not as simple as he imagined.
