Doomsday Son-In-Law: Swallowing Mutated Cores at the Start

The apocalypse breaks out during the Spring Festival. Liang Fu, an ordinary person who married into the Lin family because of "unexpected joy", was looked down upon in the family refuge. Zombies besieged the city and the refuge fell. During his escape, in order to save his nominal wife Lin Wei, he swallowed an extremely unstable "mutant core" that was supposed to be handed over in desperation, and set off on a path of no return.
