Senior Sister, Does This Martial Arts Have to Be Practiced This Way?

Once he traveled through time, Zhou Li became an unpopular apprentice in the martial arts school. Fortunately, in the awakening contract panel, the first contract partner turned out to be his senior sister. As long as you increase your senior sister's favorability, you can obtain her physical training methods and various martial arts techniques. Thus, the martial arts counterattack of a young man with mediocre qualifications began. But Zhou Li would not have thought that when he was attacking Senior Sister, he would also become the target of Senior Sister's attack. "Good junior brother, if senior sister wants to break through, she only needs this precious material from heaven and earth." The senior sister's face was extremely beautiful: "The system said that as long as you practice the exercises with me, I can get this treasure..." Zhou Li: Wait, I'm trying to increase my senior sister's favorability. Why does my senior sister want to blow up my rewards? Also known as: "Begin to become stronger by brushing your senior sister's favorability", "Ten years of martial arts training is not as good as conquering your senior sister in one day", "Senior sister, stop it, I am your junior brother"
