To evolve into a Titan Dragon, and ultimately, the Apocalypse Dragon Emperor. His check-ins yield rewards like Titan Dragon gene enhancers, brain cell enhancers, virus antibodies, and even barbeque skewers and beer! While others fight to the death for a bottle of water, Mo Shi enjoys his drinks and snacks, seemingly unconcerned with the chaos around him.
