Jingxiang Yuzhi

A man is transported to a dimension filled with monsters and constant battle. He gains the ability to claim rewards from a fight before it concludes, including gear, experience, currency, and a perfect copy of his opponent. However, to keep these items permanently, he must still defeat the original enemy. His objective is to gather and train numerous copies, eventually mastering each one. Once achieved, he can use any of these duplicates, allowing him to function as multiple combatants simultaneously.
