On the ring, the referee made a black whistle and his brothers betrayed him. Chu Lan had his right arm broken and fell from the altar into the abyss. When his life was hanging by a thread, he was picked up by the underground boxing ring and became a "consumable" who could die in the iron cage at any time.
No one knew that a mechanical sound sounded in the dying Chu Lan's mind - the "King of Fighters System" had awakened, and he could exchange blood and pain for everything. The broken bones were reorganized into titanium alloy war bones, and the necrotic muscle fibers evolved into super-fast explosive fibers.
When the boxing champion who framed him in the past raised his golden belt in front of everyone, Chu Lan returned from hell wearing a skull mask. One punch and the internal organs are displaced; two punches and the consciousness is deprived. He stepped on the career of all his enemies and embarked step by step on the road paved with iron blood and flames - the road to the coronation of the underground boxing king!
