Flood Apocalypse: My Beautiful Neighbor and I Teamed up to Survive

[The end of the flood + mutation of animals and plants + awakening abilities + no system + many women (accept women if you see them)] Overnight, the sea level rose by one hundred meters, and the plains of eastern China were covered with ocean. Animals and plants around the world have undergone unknown mutations, their sizes have skyrocketed, and human civilization has been destroyed in an instant. Whales flying into the sky, turtles in the island country, giant squid making waves in the water, giant banyan trees covering most of the country... Human beings have never been the darlings of nature. The era of living with hair and drinking blood has begun again! Superpowers have become the key to the rise of mankind again! Xu Xiao awakened his evolutionary powers, transformed from prey to hunter, and copied the genes of mutated creatures for his own use.

With all kinds of mutated creatures and all kinds of superpowers, Xu Xiao has reached the pinnacle of biology step by step! "Mutated beasts? They can gain new genetic abilities again!"
