By this point in the battle, Lu Ye didn't have much left to do. Even if he withdrew, the Nine Provinces cultivators, with their numbers and strength, could still slay the Insect Matriarch.
But he didn't remain idle.
The severed limbs and flesh of the Insect Matriarch contained an enormous amount of vitality. If left unchecked, it would inevitably be absorbed by the flesh wall and re-transform into energy to be injected back into the Insect Matriarch's body.
Thus, Lu Ye controlled the Blood River's surge, wrapping every chunk of severed flesh and limb, allowing the roots of the Talent Tree to penetrate them, absorbing and devouring freely.
In this way, the Insect Matriarch's vitality continued to deteriorate significantly.
The relentless warfare caused the Insect Matriarch's originally bloated form to become more slender, with its self-healing speed slowing down progressively.
