From the Start, I Sign In to the Undying Chaos Body

Fang Yu, a transmigrator, is reborn into a small clan, the Fang family. With the help of an ancestral relic, he enters the Cangyun Sect, one of the four great sacred sects. But his constitution is so poor that he can only become an outer disciple.

At sixteen, he is framed and falls off a cliff, where he unexpectedly awakens a sign-in System. From then on, he roams freely between heaven and earth, bound by no one.
