High Martial: Disaster Strikes, and I Can Level Up Without Limits!

[High Martial Arts + Another World + Dungeons + Instances + Planes + Anime References + Unresolved Regrets] My name is Mu Heng. A cataclysmic change trapped me in a world of instances. By the time I made it out, a century had passed in the outside world. With no other choice, I had to make a living, so I started studying in this future world and exploring dungeon instances. Fortunately, I awakened the [Fourth Calamity System]. My body is digitized, and I can level up by earning fame and killing monsters. And so I kicked off a full-on power-leveling spree! I trampled every classmate and teacher who looked down on me! I crushed every powerhouse who thought their extraordinary talents gave them the right to do as they pleased! Disaster strikes, and the rules are overturned! Only the strong can protect everything they hold dear!!!
