An ordinary young man, Chen Feng, accidentally got involved in an underground martial arts league and was forced to participate in order to survive. He was able to see through his opponent's flaws in battle, and he was able to absorb the "source of martial arts" to improve his strength. He started a counterattack from the bench and shocked the league. Investigative reporter Lin Wei sneaked in to uncover the shady story and met Chen Feng. The two discovered that there was a dark deal behind the league to force match-fixing and sell players' organs. Zhao Tianxiong regarded them as a thorn in his side and set up many dead ends. Chen Feng passed all the way and his strength soared. He finally defeated Zhao Tianxiong's trump card in the finals, exposed the shady story, disbanded the underground league, and gave the boxers in the darkness a new life.
