My Classmates Haven't Graduated Yet, but I Have Already Entered the Holy Realm

My name is Lin Xing. I am a clear and not stupid high school student who encountered an unreliable system. There was a loophole in Brother Tongzi's system, and boarding was delayed three years, so Brother Tongzi chose to crash at the beginning and restart after three years... Brother Tongzi! Do you know how I have spent these three years? ! !
