If the Insect Matriarch truly exists beyond the Divine Sea Realm, there must be something on it that can be excavated. This is one of the reasons why Lu Ye insists on refining the vitality accumulated in the Blood River. He hopes to discover something through this method.
The Insect Matriarch's vitality is immense and pure. Although during the battle, some of the vitality was used to hatch the Insect Race bodyguards, and some was used for healing, overall, the vitality consumed by the Insect Matriarch should be less than half.
In other words, more than half of the vitality was absorbed by Lu Ye with the help of the Talent Tree and integrated into the Blood River.
However, this part of the power does not entirely belong to him yet; he still needs to carefully refine it to become his own.
This situation is like a farmer who has seized a large amount of grain from the landlord's house. Now, this grain is piled up in his house, and he has to eat it to make it truly his own.
