Three months have passed since the beginning of this chapter, and the magic of the light elements has greatly increased. The teacher tells him that they are going to start practicing light-attribute elementary magic. The first thing they're going to do is chant the name of the element xiyu xi , or "the light shield." The teacher says that the chant is wrong, but that the effect is better because the light shield is fortified with water and the water repels the evil elements. This is the first time that the teacher has been able to achieve this level of magic in such a short period of time.
