Chen Fan, an ordinary construction worker, was betrayed by his girlfriend on the day the apocalyptic virus broke out and died tragically at the claws of a mutant beast. At the moment of his rebirth, he returned to the morning when his fate changed - the day before the virus was about to sweep the world. With the memory of his past life, Chen Fan knew every step of this catastrophe: in three days, 80% of humans will turn into zombies; in two weeks, mutated beasts will rule the city; in a month, the survivor base will fall into infighting among factions. In this life, he will no longer be a lamb to be slaughtered. The system suddenly came and gave him the SSS-level talent "Devouring All Things" - he can swallow any matter to gain abilities and evolution. Chen Fan gave up his escape plan and entered the crisis-ridden city. Using an abandoned supermarket as his base, he hunted mutants among zombies and collected resources among the ruins. He not only wants to survive, but also establish his own order in this collapsed world. The girlfriend who betrayed him in his previous life, and the larger forces behind her, will also surface in the end...
