Lin Yi, a 35-year-old mediocre social worker, was frustrated in life. An accident brought him back to his 18-year-old senior year in high school. Along with rebirth, there is also an "all-round life system" that does not seem to be serious. With the experience and lessons accumulated in his previous life and the assistance of the system, Lin Yi is determined to have no regrets in this life! He wants to crush the top students and become a god of learning; he wants to rejuvenate his skills and become famous in the medical field; he wants to make waves in the business world and become rich; he also wants to make up for all the emotional debts in his previous life and embrace warmly those beautiful souls that he has missed or regretted. This is a journey of counterattack all over again, and an all-round life woven with wisdom and warmth.
