I Became a Transcendent-Class Hunter with 100,000x EXP

On the very brink of the world's destruction at the hands of the demons, Tenma Tsukishiro uses a mysterious item to return to the past. When he was a hopelessly incompetent, talentless F-Rank Hunter. His regression grants him a unique trait absent in his past life: [Talentless Adjustment - 100,000x EXP Gain]. Just swinging a sword unlocks a Swordsmanship skill—and instantly maxes it out?! Reading a single book grants an Intelligence skill—and maxes that out, too! In his previous life, all he could do was watch helplessly as the world burned. But in this new life, armed with his extraordinary power, he vows to save it!
