On the iron frame bed in the boys' dormitory of Zhouzhi County Vocational and Technical Education Center, Wu Hang suddenly opened his eyes amid the muffled thunder in June. The smell of low-quality tobacco mixed with the smell of engine oil and sweat filled the nasal cavity - this was the unique smell of the training workshop of Zhouzhi Vocational Education Center, and it was also the last smell he smelled before death in his previous life. The memory of the top agent "Black Falcon" surges back with the sharp pain of the bullet piercing his eyebrows. He clenched his fists suddenly, and his knuckles made a soft "click" sound in the dim light. Outside the window, the patrol instructor's flashlight swept across the mottled walls like a searchlight, and the light spots passed over the ice condensed in his eyes. After a new life, it's time to behead those poisonous snakes lurking in the dark.
