Lin Chen was reborn as a senior in high school and was accidentally bound to the god-level group pet system to make up for the debts he owed in his previous life. He used the system to unlock abilities such as the thinking of a top student and proficiency in Chinese medicine. He first helped the eldest sister relieve her career fatigue, then helped the second sister overcome a medical crisis, and optimized the teaching plan for the third sister. He gradually resolved the plight of the eight sisters. He completely tore up the "sluggish" label of his previous life and became the most solid support for his sisters.
