Kaisha knew perfectly well how troublesome quasi-Void creatures were. Now that Du Kao had turned himself into one, he would only be even harder to fight.
Lan Hong had great confidence in Qi Lin and the others. Against a troublesome quasi-Void creature like this, sealing it away was the best solution.
During the fierce battle with Du Kao, Qi Lin had thought of the same thing.
"Xiaoli, Weilan, help me buy some time."
"No problem, Qi Lin. Go for it!"
He Weilan's fist was dodged by Du Kao once more, while the Void Energy attack Du Kao unleashed was sent flying with a sweep of Xiaoli's tail.
Then Su Xiaoli fired another beam of light through Du Kao's body, but his injuries healed in an instant.
"This disgusting thing really is a pain!"
As spiritual power clashed with Void Energy, there was no way to kill Du Kao unless all the Void Energy in his body was completely exhausted.
By then, Qi Lin was ready. She summoned icy swords from the sky, forming a circle around Du Kao.
An ice-blue barrier appeared at the same time. He Weilan and Su Xiaoli retreated outside it, then poured their spiritual power into the barrier.
Du Kao tried to charge out of the barrier, only to find that he could not.
Even bombarding it with Void Energy merely sent ripples across its surface. He could not shatter it.
"Damn it!"
After turning himself into a quasi-Void creature, Du Kao's thoughts had become increasingly rigid.
Clearly, he could have considered other methods, yet he stubbornly kept bombarding the barrier with Void Energy.
"Qi Lin, how much longer? At this rate, your barrier won't hold much longer."
"Almost there!"
Qi Lin gathered all her spiritual power and unleashed it at once.
"Extreme Ice Seal!"
