In the seemingly peaceful modern city, the protagonist is accidentally involved in a world of infinite copies called "Martial Arts Reincarnation Trial". This world is full of weirdness, dangers and opportunities. Each dungeon trial may be fatal, but you can also gain a powerful martial arts inheritance. The protagonist discovers that he has a unique "little world of enlightenment" golden finger, in which he can infinitely deduce, improve and accelerate the practice of any martial arts technique. In the struggles on the verge of life and death, he not only has to face the endless strange beasts, ancient martial arts masters and desperate situations in the dungeon, but he also has to be wary of the calculations from other trialists. As his strength increases and the dungeon progresses, the protagonist gradually discovers that these infinite dungeons are not randomly generated, but are closely related to some ancient "curse" or "contract" in the real world, and his "little world of enlightenment" may hide the key to unlocking everything. In the end, he must gather like-minded people, face the mastermind behind the scenes, break the cycle of reincarnation, and reshape the world's martial arts order.
