Chapter 163: Flower Demon Waste Utilization?

The Flower Demon captives at the Watchtower have been sought by Da Fei for rescue to no avail. Demons used the special Array atop the Watchtower to bind them, extracting their energy, and then used it to dissolve the World Tree's barrier. The energy-depleted Flower Demons were then fed with the World Tree sap drawn by the beetles of the Pool of Radiance; revived with energy, they were continued to be pressed by the demons. In short, a virtuous cycle, regenerated for reuse.

With the outbreak of the National War, due to Da Fei's early clearing and the fierce fighting that followed, a large number of beetles were destroyed, and there was no longer enough World Tree sap to recover the Flower Demons, so just now Siriel decided to simply execute them.
