(With system) (In the early stage, it is a high school daily novel. The system is just a seasoning. Later, it will become more enjoyable. When I read it, I hope I can throw away part of my brain. The author is a novice, and the writing is average and light.) The protagonist is named Zhang Fei, a 27-year-old civil construction worker. After a party with his best friend, After an accident, he was taken away by a wave of cement tankers. When he opened his eyes again, he was back in high school and the system was awakened. Zhang Fei was already very happy and could rewrite his life. What was even happier was that his three best friends also traveled back in time and were each bound to the system. Four high school students have 27-year-old souls living in their bodies. They promised to live a wonderful life, but as a result, they were always criticized by the teacher for their bad work in class. They cheated on each other in exams. The system always issued some outrageous tasks. If they couldn't complete them, there would be even more outrageous punishments.
