Only see Elder Yu arrive at the valley, high in the sky.
His expression is fierce, and he punches his chest heavily.
Pfft!
A large mouthful of Essence Blood sprays out.
Then, Elder Yu quickly casts techniques.
The Essence Blood in the air, suddenly and eerily stagnant, then merges with each other, forming several strange Blood Talismans swiftly.
Afterward, Elder Yu manipulates the black Thunder, fusing these Blood Talismans together.
At the moment of fusion completion, the black Thunder unexpectedly emits a bloody red glow.
But this wasn't the end.
Elder Yu continues to spray several more mouthfuls of Essence Blood.
He creates a large pile of Blood Talismans.
After this series of operations, Elder Yu's face also shows extreme paleness.
Clearly, losing such a large amount of Essence Blood, even he cannot bear it.
However, Elder Yu's actions were not in vain.
At this moment, those black Thunder have completely turned blood-red.
