The Frenzor Assassin evidently didn't appreciate the joke. He continued to charge forward with a terrifying bellow. Even though hundreds of mana bolts and laser fire struck him, he kept on going, an unstoppable juggernaut of ferocity.
In the face of such a horrifying foe, I calmly stepped forward. Partially to shield my comrades from the berserker's charge, and partially to execute my technique. Turning Hei Yue so that the tip of its black blade faced the ground, I plunged it into the concrete and whispered a single incantation.
"Absolute Zero."
Atop my shoulder, my chibi Black Tortoise stiffened and then he allowed dozens of azure strands of mana to flow out of him and into my sword.
Then the whole place froze in an instant. The corridor turned into a tundra, and the Frenzor Assassin was encased entirely in an icy tomb, suspended in mid-charge.
"…eh?"
