Blood vitality and Spiritual Power were the two major directions of cultivation for Spirit Stream Realm cultivators. Abundant blood vitality meant a powerful physique; no matter which faction a cultivator belonged to, having a stronger body was never a bad thing. Spiritual Power went without saying—it was the foundation of a cultivator's cultivation and combat.
The speed at which these two flowed was directly tied to a cultivator's strength.
Why could a cultivator's strength increase greatly after switching to a Heaven-Grade Cultivation Technique? First, because after switching to a Heaven-Grade Cultivation Technique, a cultivator's control over their own Spiritual Power underwent a huge leap. The second reason was that the speed at which Spiritual Power flowed through the body also underwent a qualitative change.
This Royal Jelly could increase the flow speed of blood vitality and Spiritual Power. That was equivalent to strengthening a Body Cultivator's physique while also increasing a cultivator's strength.
Take Lu Ye, for example. After drinking a bottle of Royal Jelly, his cultivation had not changed at all, but the strength he could unleash was greater than before.
He just did not know whether this effect was permanent or temporary. If it was only temporary, then its value was not great. Some Spiritual Pills could do this, such as the Qi Burst Pill, a Spiritual Pill that could briefly increase a cultivator's strength. However, its aftereffects were very severe; with the slightest carelessness, it could result in the serious consequence of damaged Spiritual Apertures.
If it was permanent, then the value of this Royal Jelly was immeasurable.
The effects of the Royal Jelly still needed time to verify; for now, they could not be seen.
Lu Ye turned his mind to the Talent Tree, gazing at the area of the Talent Tree where orange-red flames burned.
