Heavenly demons were lifeforms that were, in essence, intangible existences formed from the evil of all beings across the heavens. When used by cultivators, they were both calamity and opportunity.
Their varieties were so numerous they could not be counted at all, and new heavenly demons were being born at every moment. The Demonic Realm was also one of the few "large maps" capable of connecting to the myriad worlds of the heavens.
Unfortunately, intelligent beings found it difficult to enter such worlds of evil thoughts. They would be rejected by the Demonic Realm and subjected to rather severe targeting.
The gap between the upper and lower limits of heavenly demons' strength was enormous.
Fishing for heavenly demons was an extremely dangerous act, so the strength of the bait had to be grasped properly. The Six Desires Heavenly Demon Diagram was no invincible treasure either; it was merely especially effective against heavenly demons of the Six Desires Demon Lord's lineage.
Therefore, the Heavenly Demon Larva that Wang Yu fished up was also a newborn of this lineage.
Its specific category would be determined by the types of emotions from sentient beings it absorbed during its subsequent cultivation. Thus, during its infancy, its malleability was extremely strong, enough for Wang Yu to perform more modifications on it.
His rearing plan was to use the Demonic Evil Thoughts he had refined himself as nourishment, ultimately raising a Myriad Transformations Heavenly Demon and allowing his Innate Demonic Fetus Body to enter a more mature stage.
Since it was a demonic fetus, it naturally had an adult form.
This was also the main reason Wang Yu believed this secret art still had potential for further advancement.
At that moment.
Using alchemy to regulate the bait's strength, he finally fished down a Heavenly Demon Larva.
