In this chapter, we learn that the evil spirits of the Nine Dynasties have joined forces to form a single evil spirit, which is called "the extremely evil spirit" . The evil spirit is so strong that it can only be destroyed by the annihilation of the entire evil force. In other words, if the evil force is completely annihilated, the evil spirit will no longer exist. This is a big deal, because it means that the enemy will be able to destroy all of the evil forces in one fell swoop.
