Li Lei, an unemployed young man, had an unexpected encounter when he was hit by a cup of milk tea. The remnant soul of Diga got into his body and became a "cyber demon body". During the day, he worked as a security guard in the college to deal with strange things, and at night he was forced to learn cultivation. The magical girl chases him and shouts to catch the devil. Basketball girl Wang Cuihua's red rope can suppress his devilish nature. From eating and waiting to death to catching bricks with bare hands, he has embarked on a counterattack since then.
