Rebirth: Limitless System

Read Rebirth: Limitless System / 重生我获得了无级别系统
The protagonist, Yan Hanshuo (32 years old), hailed as the world’s strongest hunter, leads his team into the most difficult dungeon in existence — The Abyss of Sighs. However, before the raid begins, his so-called teammates secretly replace his buff potion with a drug that shrinks his body. The several SSS-grade top-tier pieces of equipment he was wearing are stripped away one by one, and his teammates escape, leaving him helpless.
By a twist of fate, Yan Hanshuo is reborn, and this time, he awakens the Limitless System. Trapped in a weakened body, he vows to use the power of the Limitless System to hunt down each of the traitors who betrayed him… and reclaim everything that was stolen.
