[Shuangjie + campus + passionate group portrait + system + time travel + level-breaking mission + multiple protagonists + exciting fighting stories + multiple CP sweet pets]
Before Xu Shifei was about to commit suicide by jumping into the river, he accidentally traveled back to high school! I also obtained the mission system by accident! And at the beginning, he successfully conquered Xu Zhisheng, a top combat power with an "S" level potential! There is also Xu Guoliang, a top strategist whose brain power is also at the "S" level! But this system seems to be different from others? The tasks are ridiculously difficult! Will the host die if the mission fails? What a joke! This seems to be different from other people's systems!
