The Killer Teacher Is so Happy

The neon lights on a rainy night, and the golden lenses reflect the coldness of the passing of life. He is "Shuang Wai Wai", a top killer who is frightened by the dark web. He can calculate thirty-seven fatal angles by pushing his glasses with his fingertips. After an ordinary mission, the organization issued a cold command and threw him into the dazzling campus - sneaking into Xinghua Private High School and pretending to be the mathematics teacher "Ye Feng". The goal was to monitor Lin Xiaoyu, an ordinary girl in Class 7 of Senior High School, and wait for an opportunity to eliminate his father, Lin Guodong, the core scientist of the "Tianshu Project". The podium became his new sniping point. Facing the noisy and chaotic classroom, a piece of chalk head filled with terrifying kinetic energy accurately penetrated the desk and killed all the provocateurs. The lesson plan book was rolled up, and the ribs of the school bully were severed; The secret warmth of the class quietly melts the ice, and the threat of the underworld inspires protective instincts. When the organization's cold warning and the truth about the "Tianshu Project" related to the family and the country were put in front of us, and when the former "Poison Scorpion" sneaked into the campus with a deadly poisonous scent, the "Shuang Wai Wai Wai" gun deviated from the set goal for the first time. The podium overlaps with the battlefield, and chalk dust and blood fly together. In order to protect this group of students who once regarded him as a "monster", and to protect his respectable father and important weapon of the country, he risked his life as a traitor and used himself as a shield to declare war on the entire dark organization! From a ruthless killer to an unknown guardian, can Ye Feng find a way to the "human world" for himself between the chalk dust and the blood light? The answer to the last math question in the classroom has already been written on the blackboard - **A (guard) + B (kill) = home**.
