The longevity elixir developed by Gao Jincheng mutated, but no one realized it. Unexpectedly, it leads to a catastrophe, and no one is to blame. Wild animals turn into humans, and disobedient and difficult-to-survive animals mix into the noisy market... A life-and-death battle between humans and animals is about to begin... The winner is king and becomes the master of the world. Wild animals that become humans have human emotions. People are still ordinary people. This is what things are like.
Purpose: Instead of coveting immortality, it is better to face death and fight to the end.
