Bab 720: 719. When in doubt, consult the universe_1

```

Lu Ban had seen the demise of the civilization that invented Pure Fire in the Splendid Realm.

He knew that Pure Fire itself was a highly potent form of Pollution, fueled by souls, wills, and intense emotions, and once ignited, would never be extinguished.

Through special means, the shrine maidens of the Great Shrine of Harmony Island could control Pure Fire to some extent and use it for themselves, all thanks to the very first shrine maiden, who became the Divine Sakura.

Her soul forever resides within the Divine Sakura, maintaining the Pure Fire by absorbing the shrine maidens' despair before death.

Such a flame was indeed very similar to the Spirit Torch of Night Country.

However, the Spirit Torch itself does not consume everything around it; it only burns upon the mages, using the light it produces to drive away Demonic Beasts, and its burning flames can indeed affect Demonic Beasts without harming common people.
