Ma Chao, the king of the Chinese military, was betrayed by a traitor during an undercover mission to a small country in Southeast Asia. He was accidentally captured alive and tortured to extract a confession for three days and nights. After no information was obtained, Ma Chao was brutally sent to the park and had both of his waist removed alive. On the verge of death, Ma Chao was pulled by a mysterious force and his soul accidentally traveled to a parallel world and was reborn in the body of a cowardly technical school student with the same name. Just when he felt despair facing this frail body, a golden light exploded in his mind - "Ding! The host's strong obsession with life is detected, and the 'Waist King System' is activated!"
What the system gave him was a pair of quantum-enhanced kidneys known as "stainless steel kidneys"! This pair of new "waist kings" not only allowed him to regain peak physical fitness, but also brought him strength, endurance and recovery capabilities that are beyond ordinary people. The former king of special forces, in this seemingly ordinary new world, will rely on this pair of shocking "big waists" to start a more passionate and exciting legendary life from campus to city, from ordinary to the top!
