I Signed In at the Demon Cave for a Hundred Years and Discovered That Cultivation Is a Scam

Lin Hao transmigrates to a world of immortal cultivation and becomes the genius son of the Pavilion Master of Tiangang Pavilion.

From the start, his cultivation is crippled and he is imprisoned in a demon cave. Fortunately, he awakens a sign-in System.

As long as he signs in at designated locations, he can earn generous rewards.

"Ding! Sign-in successful. Obtained Starry Dantian Sea!"

"Ding! Sign-in successful. Obtained Starry Sword!"

"Ding! Sign-in successful. Obtained Nine Dragon Treasure Orb!"

Years later, when Lin Hao steps out of the demon cave, he discovers that he is already peerless in the world. But it turns out that immortal cultivation is a hoax.
