When 40-year-old Pei Qing travels back to his high school days, why do you want me to time-travel! Why do you want me to go to high school again? Why do I have to take the college entrance examination again! It’s not good for me to sit quietly in the office and paddle What! Wait, after time travel... Has her brain improved? It smells so good! Responses speed up? It smells so good! Fresh and hot girlfriend? What if the future father-in-law and mother-in-law look down on me? It only takes a second for Pei Qing, who has become a genius, to think: Are you kidding, can't reach the pinnacle of life after time travel? Then he didn't live like a pig in his previous life!
