The chapter opens with a description of the blood devil emperor's sword. It's the same sword that the blue dragon has been using since the puppet's destruction. The blue dragon asks how he could possibly use such a big sword, since he has no other weapon to use. The narrator explains that a sword spirit is a kind of owner's obsession with a specific object, like a sword. A sword spirit, the narrator explains, is like a person's mind, which is filled with "dirty stuff" . He explains that in order to wield a huge sword like the one in this chapter, you need a certain amount of your own sword spirit in it. This means that the sword spirit will use the big sword to fight, not just sizzle . This is why you need the herb garden. The herb garden is a place where you can cultivate your own magical herbs. The chapter ends with a soliloquy about how he's made a "breakthrough" by using his sword spirit.
