Underground boxer Yang Xue accidentally activates the "Martial Arts Deducer", which can deduce moves, techniques, and battle scenes with zero loss. In the early stage, he hunkered down in the market to recuperate, and used a deduction device to sublimate his street fighting skills into top-notch killing moves. In the later stage, he was repeatedly provoked in underground boxing matches, martial arts academies, and family disputes. Every time he was forced to a desperate situation, he would show off his cards with stronger deduction results, and from "Unknown Boxer" He grew into a "humanoid weapon"; he later revealed the truth about being abandoned by his family in his childhood, and continued to break through the limits of deduction in global martial arts tournaments and ancient ruins. Finally, he broke the bottleneck of modern martial arts with "unlimited deduction", ascended to the position of the God of Martial Arts, and reestablished the rules of martial arts.
