End Ruins: Humanity's Last Safe Bunker

Doomsday world, zombie outbreak! The protagonist is a fat man who lives in a rented house all year round after graduation, drinking Coke and watching zombie dramas. I often imagine that the zombie virus breaks out, and I become the protagonist, fighting monsters and counterattacks all the way, and becoming the male god in the eyes of thousands of girls. Just after falling out of love, the protagonist fell asleep drunk, and when he woke up, he actually traveled to the zombie world. Moreover, the body occupied by the protagonist after traveling through time is actually the strongest person in the ruins of the end of the world! How can a protagonist with no physical strength, lack of knowledge, and zero skills lead mankind to save itself? This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
