Cultivating in the City Through Sign-Ins, Everyone Thinks I'm a Grandmaster

Chen Ye, an unemployed college graduate and avid reader. On his first sign-in, he receives a complete cultivation technique and a cultivation base at the peak of Core Formation, all at once.

Everyone thinks he's a Grandmaster. The martial arts world venerates him.

The martial arts world has its own hierarchy: Body Tempering, Houtian, Xiantian, Grandmaster. At the very top is the Great Grandmaster.

But no one knows he's actually cultivating immortality. His cultivation is far above that of a Great Grandmaster. He starts out at the peak of Core Formation, with Nascent Soul, Soul Departure, Spirit Division, Body Integration, and more still to come, each stage higher than the last.

And yet he's a max-level newbie: he knows every cultivation technique, but he's terrible at fighting.

There is no limit to sign-ins, and the mortal world is only the first stop. Beyond it lie the world of cultivation, the immortal realms, the divine realms... No one can say how many levels lie beyond those.

An avid reader gets a sign-in, starting out at max level. I've read this story before.
