Rebirth at the Doomsday, Two Heavens of Ice and Fire

The end of the world is coming, global temperatures are abnormal, and extreme cold and extreme heat alternate with each other. Along with earthquakes and volcanic eruptions, the world fell into chaos, and law and morality disappeared with the advent of the end of the world. All kinds of materials are in short supply, "bartering women" and various unethical things are commonplace, and all kinds of illegal crimes are commonplace. In order to survive, the ugly side of human nature is exposed. A bottle of water, a pound of rice or a pack of instant noodles can make people kneel down and lick them. The whole world seems to have returned to a primitive society, where everything is based on survival, and all principles are aligned with materials. The money in the account is just a bunch of cold numbers, and the banknotes in the hand are worthless, and it is so hard to wipe your butt with it. Xu Shang was lucky enough to be reborn a year before the end of the world. He vowed not to be a licker anymore and used his superpowers to make crazy money and hoard supplies to build a doomsday super villa. Others can only chew tree bark and eat mice, but he is tired of eating seafood and abalone. For others, living alternately between hot and cold is like a purgatory on earth, while he is comfortably flirting with beautiful women in a temperature-controlled villa. In his previous life, he had a cowardly character and was the goddess's licking dog, but in the end he died under the goddess's knife. In this life, monsters around the world have mutated, and the earth is like a cage, with genes locked... Why does the end happen? All kinds of unknowns are like a mystery... Can Xu Shang break through this chain?
