The Ninefold Thunder Dragon was Levin's trump card. Lumi had heard from her father that even when he was in good shape, using it would leave him weak.
Now that he was badly wounded, using the Ninefold Thunder Dragon again meant he was ready to die and take Wyatt with him.
Even if Lumi wanted to stop him, it was already too late.
With Johnnie's help, Levin seized the moment while Wyatt was distracted and unleashed his trump card.
He watched the Ninefold Thunder Dragon with tight nerves and only relaxed when he saw Wyatt's body shattered by it.
A gush of blue blood streamed from Levin's mouth, eyes, ears, and nose. He weakly grabbed the edge of the Thunder Pool and wiped the blood from his face.
Forcing the Ninefold Thunder Dragon had pushed him to the brink of death.
Levin propped himself up and slowly turned his head toward where Lumi's voice had come from. He tried to speak, but no sound came out.
His vision blurred. He couldn't see far, and he couldn't hear anything.
