My Junior Brother's Realm Is Unknown, and He Grows Stronger When Facing the Strong

Pei Yi transmigrated into another world and spent more than twenty years as an ordinary person with no aptitude for cultivation.

He thought his only master was an ordinary person. It turned out he was a great cultivator who had ascended to the immortal realm.

He thought his parents had abandoned him. It turned out his father was pushing himself to the limit, cultivating desperately to become the family head, rewriting the clan rules, and bringing Pei Yi home.

He thought he had no golden finger and would have to live an ordinary life. Then, when he turned twenty, the System suddenly appeared.

But because Pei Yi was so lackadaisical about activating the System, his reward was cut in half. Instead of granting him invincible cultivation, it made him only half-invincible. He could go toe-to-toe with anyone. He couldn't lose, but he couldn't win, either.
