The first year of class zero at the Donghai Academy is over, and the students are back in their classrooms. The teacher, wuchangkong, is still teaching, but the students have been separated into two groups, one for advanced and one for beginners. The first group is made up of students who lack physical strength, while the second group consists of those who do have physical strength. The class is divided into three groups: the advanced group, the beginners group and the intermediate group. Wuchangkong tells the students that they should learn about the mechas at the advanced level, since the soul master has been a mainstream profession for thousands of years. However, with the civilian advancement of technology, the soul guidance device has gradually evolved into use. In the future, the students will choose one of the three to become their second career. The beginners group criticizes the students for not having the proper qualification for a second career, for neglecting their own performance, and for being arrogant when facing an enemy. .
