“Zheng Kai!!”

It terrified Kou Tingting to see Zheng Kai in such a bestial state. She was stunned, terrified, and filled with horror at the sight.

What was wrong with Zheng Kai, she didn’t know. She just knew this wasn’t right. The way his soulforce was fluctuating made it feel like he was on the verge of self-destructing.

Additionally, Kou Tingting wasn’t quite familiar with the Vampiric Demon Edge, but as the daughter of the Crafting School’s headmaster, how could she not know about demon armaments? Anyone would be able to guess that Zheng Kai was using his own blood to strengthen himself. It didn’t matter if soul cultivators could replenish their blood faster than commoners, anyone fighting this way would most definitely run out of steam...
