Zhang Heng didn't know who the shooter was, but the mysterious gunman must have used the god-slaying bullets that had attacked Thor and the Succubus, because ordinary bullets obviously couldn't do this kind of damage.
Zhang Heng had already recognized the person who was blocking his way as Hephaestus, the god of fire and craftsmanship in Greek mythology. Although Hephaestus wasn't as famous as Zeus in modern times, he wasn't a nobody, in the end, he was knocked down by a single bullet. The lethality of this bullet was even higher than the first version of the god-slayer bullet that he had seen before.
And that wasn't the end of it. As Zhang Heng continued to move forward, gunshots rang out one after another, and there was more than one. It was as if an armed squad was following behind him, silently escorting him.
