Zhang Chen, a "veteran" who wrote materials within the system until his soul left his body. His biggest regret in life was that he was terrible at mathematics in his senior year of high school and was too cowardly to pursue Bai Yueguang. An accident (or rather, an "accident" he engineered) actually made him go back to being seventeen years old! As soon as he landed, he was slapped by his best friend Chen Xing and said, "Damn it! Zhang Chen, you know how to teleport?!" With no time to explain, Zhang Chen's eyes were fixed on the front - the boy who lowered his head and kicked stones, read the gold version of "Boys and Girls", and whose math papers were always covered with red crosses! The resentment that had been accumulated for half a lifetime exploded in an instant! Zhang Chen rushed up and slapped the confused young man: "Boy, look in the mirror and see who I am?!" When the past self meets the "trash" of the future, Mars hits the earth! "You can't hold up the wall with your math mud!" "You live like a walking zombie!" Do you dislike each other to the extreme? Then swap lives for a week! The adult soul goes back to the senior year of high school to study hard at math and chases the goddess, while the young soul travels to the future to experience a "successful" life! Result? The adult Zhang Chen, who has a full-level "God of War" experience in politics and history, faced Teacher Wang's math class, but his brain was still shut down and he was sweating. He chased Bai Yueguang out of the death scene... It turns out that time travel can't cure the cowardice and fear of mathematics in his bones! Zhang Chen, a young man who thought he could enjoy the fruits of victory, was overwhelmed by the mortgage, the boss's roar, and the incomprehensible official documents, and his efforts were polished off in three days... The "freedom" of adults is all bullshit!
