The Ultimate Way of the End Times: from a Slave to a Martial Saint

[Apocalyptic mutated creatures + Ji Dao + physical sanctification vs. Supernatural evolution + decisive killing] Wu Yan woke up from the slave cage, and when he opened his eyes, he saw a person with supernatural powers grabbing his trouser legs and begging for death, and there were two mutating zombies next to him. Decisively ending the person seeking death, a "panel of force" appeared in his mind. From then on, a human butcher appeared in the apocalypse who had no special powers but could make a fortune with his body. As long as there are kills, you can become stronger. Disgusting, bloodthirsty zombies, kill them! The ultimate mutated creature transformed into Cthulhu, kill! Whether it's a mutated creature or an army of zombies, everything in the way will be chopped down. Just after Wu Yan's body transformed several times, he discovered that his blood could evolve his own super-powered pets. … Many years later, Wu Yan was lying on the beach basking in the sun, with his own apocalyptic harbor behind him.
