I Rely on Infinite Retracement to Become Stronger

This is a world where ferocious beasts run rampant, humans practice martial arts, and the weak eat the strong. Ye Wen accidentally got an infinite rewind system while playing a super-sensory game, and he cheated on his life ever since! Spawn monsters in the wild, unlimited retrieval! Even if you get experience and items, you won't die! PK duel, unlimited retracement! Failure is success, if you lose, try again! What about being born with a junk physique? See how Ye Wen uses the infinite retracement system to become invincible!
