Returning from the Desert Island: I Am Looking for My Enemy, and I Will Kill Him Without Mercy!

In the third month of the apocalypse, I, Shi Xiaobei, was personally pushed off the escape boat by my best brother, Zhao Feng!​ "Trash like you should be fed to zombies!"​ He stepped on my hand and laughed wildly, snatching away the last half of the bottle of water, leaving me struggling in a sea full of mutated zombies.​ Drifting to the Island of Death on the brink of death, I unexpectedly awakened the power of "Swallowing Evolution" - the zombies that bit me turned out to be the nourishment for me to become stronger!​ Three months later, I returned to land with the power of an island full of zombies.​ Zhao Feng? He had already joined the Black Crow Organization through betrayal and became a demon who preyed on survivors!​ Did he think I should have died on a desert island?​ Oh, wait!​ You owe me your life, and I want you to pay it back thousands of times!​ The Black Crow Organization is blocking me? Total destruction!​ A bastard who dares to protect his enemy? Kill without mercy!​ In these last days, my only purpose for Shi Xiaobei's return——​ Crush Zhao Feng's bones inch by inch!
