In this chapter, we learn that other students have saved money for their studies, but they have not been able to pay for the entire course. This is because they have spent most of their money on foundation and tua tao construction, and they do not have enough money to cover the cost of the course. So, they have signed a contract to buy the course from mu su. In order to learn more about their problem, we're going to go to their foundation building room. We'll find out how much they charge for the course, and then we'll figure out a way to tailor a solution to their problem.
