Shen Yaomiao pressed down the last trace of Dao Yun, and her energy trembled - Nihen came back and bit his wrist. He is a clerk in the archives of the Public Settlement Police Station and an intelligence agent of the underground party codenamed "Blue Bird". In Haiyan, a city divided between Britain, France, Japan and Germany, traces are crimes. Bullet casings, footprints, residual aura, exposed air... Any trace can kill someone. But he is different. He can eliminate traces and compress and transfer evidence at the physical and Taoist levels. Japan Special High School traces his online? He hurriedly wiped out the chi in the entire room before searching. Did Agent 76 target his contact point? He made all traces disappear. However, the negative marks will come back - every time they are eliminated, they will leave an irresistible mark on him. What's even more fatal is that his handwriting is the only unforgeable part of Tao Yun. When Ryosuke Matsumoto looked at the archives room with the handwriting comparison report, Shen Yaomiao knew that he only had one chance to eliminate it. But this time it eliminates the need to borrow the luck of the beggar on the street corner. If he takes action, he will permanently lose the protection of "The Trace of Righteousness". If you don't move, your identity will be exposed. Move, conscience collapses. Tonight, he wants everyone to know that the wings of a blue bird do not need to be stained with the blood of civilians.
