Chi Yan, China's most secretive special forces, has no number and no files. During the overseas mission code-named "Fire Evacuation", Lu Yan (codenamed "Fire") was targeted by white phosphorus bombs due to intelligence leaks. He was the only one among the 117 people in the team who survived. He shouldered the blood feud, tracked down the real murderer, rebuilt Chi Yan, and finally completed his revenge and transformation.
