Although Billy was suffering again even while playing on defense, he could see some blood spraying around from Zenis' arms. His previous attack damaged him, and he hadn't recovered yet… That was weird, though. He was supposed to have Life Manipulation, so he was supposed to be able to enter an over health state. It wasn't like a single attack like that could have caused dozens of thousands of damage.
"Ah, I get it now…" Billy thought.
Billy's realization made him lose focus for a second, and then Zenis almost split him in half with his two swords. One of them was blocked by the glaive, and the other cut the left side of his stomach until he used Reflect. Zenis was pushed back for a couple of meters.
"I was wondering how you could create such a material that apparently can expand endlessly and react automatically to all kinds of attacks," Billy said. "I was calling that mercury armor, but I guess calling it blood armor would be more accurate."
