Discovering the unhatched eggs of the Flame Devouring Spider could not be called anything less than a major harvest.
Those adult Flame Devouring Spiders that had eaten people were wild and hard to tame. Once they grew old and could no longer spin silk, or could not endure captivity and killed themselves, their fate would be to be slaughtered for silk and refined into artifacts—a one-shot deal.
But if Flame Devouring Spiders could be tamed from infancy, there was a strong chance of domesticating these demonic beasts into household spirit beasts. Then the Zhou Lineage would gain a steady new source of income from selling spider silk, further strengthening the Lineage's foundation.
Moreover, Flame Devouring Spiders could do more than spray silk for profit. They themselves possessed considerable combat strength and could serve as Lineage combat power at critical moments.
Just because Zhou Yang had dealt with those eight Flame Devouring Spiders with ease did not mean these demonic beasts were weak. That had entirely been the result of his cultivation and artifacts crushing them.
If it had been a Qi Refining Cultivator—even Zhou Yang at Qi Refining Layer Nine—encountering eight Tier 2 High-grade demonic beasts like these, escaping alive would already have required burning incense in gratitude.
As Tier 2 High-grade demonic beasts, Flame Devouring Spiders had more than just the ability to spray silk. Their venomous fangs contained terrifying fire poison that could rapidly dehydrate and kill living creatures once injected into their bodies. Their eight spider legs, each four to five feet long, could also be used as short spears, with power comparable to Tier 2 High-grade flying swords.
If Qi Refining Cultivators encountered Flame Devouring Spiders in the cramped confines of an underground cavern, holding their ground in a one-on-one fight would already be quite impressive.
