"Cultivators liked to categorize weapons based on this sentence: Heaven and earth are united; there was no difference between them when they were originally one."
"At the heaven-grade, weapons will undergo qualitative changes. They might even be able to break the limit if the circumstances are right. One can wield them with cultivation methods from the schools of Confucianism, Buddhism, and Taoism, and unleash great power. For example, bows and arrows can produce energy arrows; sabers can produce saber rays. Desolate-grade weapons see an increase in destructive power, defenses, and a stronger bond. Flood-grade weapons are incredibly tough and have special skills. Some weapons are only useful when they've reached the flood-grade. An example of this would be the Confinement Seal."
Li Yunzheng asked, "So, does this mean that this is the special skill of the Sea Spirit Pearl? Is the Sea Spirit Pearl a flood-grade weapon?"
