When Wang Mang and his girlfriend visited the zoo, they were swallowed by a snake pit, but were accidentally reborn as a python and acquired the Devouring Evolution System. He successively absorbed fish, loaches and other creatures in wet markets, reservoirs, lakes and other places, and evolved into a starry sky python that can swallow the world. As his strength increased, he uncovered the zoo's blood python conspiracy, and at the same time explored the secret of the world's aura recovery.
