Thousand of blood essence threads were currently swirling in the sky.
Gu Yao's words were like a deity's judgment and the threads descended upon the people. Lin Mu was watching from below and could tell that the power of the ability that Gu Yao was using was much more than before.
"How did it suddenly increase in power?" Lin Mu questioned.
"He is sacrificing his longevity to increase the potency of the ability… you need to get away too," Xukong replied.
A blood thread appeared in front of Lin Mu too, but he cut it with his short sword. The blood essence thread dissipated and another one soon appeared in its place. Lin Mu kept on cutting them while observing Gu Yao. Lin Mu wanted to see how his skill worked, so as to find out flaws in it.
