Quan Mín Zhuan Zhì: Yulongshi Shi Zui Ruo Zhiye?

When a game world merged with reality, monsters roamed the streets, and dungeons sprang up everywhere. To fight off the fearsome monsters, everyone gained a profession and tried to level up as much as possible. Lu Fan unlocked a hidden profession — dragon trainer. Everyone thought it was a useless profession because dragons are too fierce to be tamed. But luckily, he also awakened a super-secret treasure map system. Now the world will tremble, as Lu Fan and his dragon sweep across the sky!
