100 Days of College Entrance Examination: My System Is Going Crazy

In the third month of spiritual recovery, the whole world was in chaos. Animals began to mutate, disasters struck one after another, and various countries secretly formed extraordinary troops. But these have nothing to do with high school senior Xu Rui. He just wants to pass the college entrance examination safely, get into a good university, and stop his mother who sells onions at the vegetable market from getting up at four in the morning to stock up. However, that night, a mutated cat larger than a Tibetan mastiff blocked the alley on his way home. At the critical moment of life and death, a ray of light hit his brain. [System has been bound] [Kill enemies to upgrade] [Current level: Lv.0] Xu Rui held the blood-stained steel pipe tremblingly, looking at the corpse on the ground and the experience points that popped up on his panel. He suddenly understood something—— This world will no longer be reasonable. Just talking about fists. So he started hunting wildly in the city late at night. Abandoned construction sites, underground garages, old city sewers... Wherever there are mutant creatures, he is there. His level is soaring day by day, and his strength is getting stronger and stronger. But he hid it well. During the day, he was still the taciturn little transparent guy in the class with mediocre grades. Until one day, in the actual combat test of the province's joint entrance examination, he punched through the test target. There was silence. In the monitoring room, several people in black uniforms stared at the data on the screen with solemn expressions. "This student... Has abnormal numerical values." "Check his background." "No need to check." In the corner, a middle-aged man wearing glasses said slowly, "He is in my class. I have been watching him for three months."
