In this chapter, the reader is introduced to the "martial soul fusion technique" , which is a type of martial art that uses a person's soul to fuse two opposing energies. In this case, the soul of the person who is being fused is lower than that of the other person. The soul of a person who has a lower soul power will be able to fight with a higher soul power, and so on. In other words, if you have a lower level of soul power and a higher level of energy, you're going to have a harder time fighting with the higher one. This is a good thing, because it means that your soul power is going to be stronger. After reading the letter from nana, the student is relieved, and he begins to study and cultivate again. One month later, he has regained his soul power to the level of 14th.
