The math teacher who worked hard to pass the exam turned into a debt-ridden senior sister of Jianzong. One day, she will chop down the house, and the next day, she will chop down the mountain. The entire Wan Chong Sect was about to be hacked, and it already owed 90 million spiritual stones when Qin Yang came! The road to repaying the money is long. Others don't give up for five buckets of rice, but she teaches others Lagrange for a piece of spiritual stone. Others ask her why her sword is so powerful? She answered: Because of calculus. Everyone asked what this was? She replied: Three thousand spiritual stones cover the calculus course.
