When Chen Mo was delivering food, he picked up a USB flash drive, which contained an unfinished game engine called Bloodline. After practicing for three months, my hand speed reached a professional level. The price was that my right arm would cramp for half an hour after each burst. He used this skill to try out for an e-sports club, and in the first ranking game he single-killed LPL champion mid laner Jiang Wenbin. Jiang Wenbin took revenge and bribed the coach to give him small shoes. He always arranged the best teammates in training matches. After sitting on the bench for two months, Chen Mo finally got his chance - one hand was injured in the starting lineup, and the coach forced him to play. Thirty thousand people were sitting under the stage, opposite Jiang Wenbin. Chen Mo stretched his cramped right arm and inserted the USB flash drive into the competition computer. No one knows that this computer's firewall cannot block a deliveryman's code.
