In the winter of 1937, the entire Jiangdong Province fell. In the name of "using China to control China", the Japanese military's special high school secretly launched a plan to eradicate all civilian martial arts forces. Chen Fangxi, the deputy leader of the Jiangnan Wulin Chamber of Commerce's "Lifeng Hall", was arrested for a line-protection operation. In the interrogation room, Doihara Shizuma's torture instruments were stained with blood, but he discovered that the tortured man had severe mysophobia - handkerchiefs, neatly folded coats, and fingertips that were wiped repeatedly. 'Do you want to recruit or not? ' Chen Fangxi raised his head, his eyes as calm as a pool of stagnant water: 'Tell me the rules. If the Jianghu people do not take action against civilians, you have broken the precept. Tonight, someone will do justice for God. ' Three hours later, Toru Miyamoto, captain of the Koto Provincial Military Police, received an anonymous report: Someone within the Super High School had an affair with the guerrillas. On the same night, the traitor Ma Hanzhang died suddenly and mysteriously in his apartment, leaving a handwritten confession before his death. Doihara Shizuma was furious, but he didn't know that the real chess player was hiding in the shadow of the torture hall, using a set of extreme thinking of interrogation and counter-interrogation to drag the entire special high school into a quagmire of cannibalism. What Chen Fangxi has to do is never just to get out alive - he wants the enemy to destroy his plan to eliminate weapons with his own hands.
