Unit 516 Is More Terrifying Than Unit 731

Hell is in the world, and poisonous fog locks the northern border! "Unit 516, a more terrifying existence than 731" reveals the Japanese army's most secret demon research institute! In 1939, in Qiqihar, Heilongjiang, with a secret order, the "516th Unit of the Chemical Department of the Kwantung Army" was quietly established under the iron heel. It is the "poison brother" of 731, but it is more insidious, more deadly, and has caused deeper disasters! Chen Tiezhu, a kidnapped Chinese laborer, carries deadly iron cans labeled "pine root oil" in pungent chemical fumes every day. He witnessed his companions' skin ulcerating and suffocating to death in the silent poison gas, and he also witnessed the hellish scene of the Japanese army testing "new drugs" on living people. Under the numb body, the flame of revenge is burning. Lin Wei, on the surface, is a docile nurse in a Japanese military hospital, but in fact she is a top soldier in the underground intelligence network. Medical files recording the strange symptoms of "special casualties" and top-secret information pointing to "516" were quietly gathered in her hands. She knew that she was walking on the edge of death, just to uncover the truth that was more terrifying than death. From the poisonous smoke in Nomenhan to the poisonous rain in Zhejiang and Jiangxi; from live experiments in laboratories to large-scale massacres on the battlefield... The demonic hands of 516 silently harvest lives and pollute the earth. However, the devil's sins did not end with the surrender in 1945. In 2003, there was a loud noise in Qiqihar, and a poison gas canister that had been buried for more than half a century leaked. Innocent citizens were brutally poisoned in peaceful times, and history echoed in the most cruel way... Today, the 516 ruins stand silently, a silent accusation and eternity.
