"Bang!!"
Two muffled gunshots rang out in succession. Under Hell Vanguard's sniping effect, two streaks of light, one black and one red, struck the Echo Demon's skull within 0.13 seconds.
As though in slow motion, the sharp tip of the armor-piercing round crumpled the instant it struck the demon, spreading across its surface like a flattened copper flower. At that same instant, the armor-piercing charge inside produced a dazzling jet of metal.
