The chapter opens with the narrator giving a lecture on foundation building. He explains that in order to be a good student, one needs to know how to build a foundation. He tells the story of a third-year student who has not yet finished his foundation building and is therefore not allowed to leave the university with a certificate. The narrator explains that he needs to lay a foundation first, and then he will be able to leave with a diploma. After the lecture, the narrator tells the students to follow his instructions and follow the school's social media accounts. He says that he will go to the university in the afternoon to check on the students who have not yet completed their foundation building, but that there are still students who need to complete their studies. After lunch, Mu Su takes his sister to the yard, where he is studying the textbook "Building Foundations : Theory and Practice" . He notices a luan bird, and decides to stop calling for the bi-winged bird. He then goes to the finance office and tells them to add him as a friend. The two siblings return home, and Mu Su begins to read the textbook. He finds that the textbook is very easy to read, and that he can charge up the price of the textbook to make it easier for students to read it. He shows off his new production line, which is fully charged up the next day. The figurines are completely loyal to their master, and will not reveal any information
