Back in the small town, Zheng Yichen found a haystack to sit on and started to adjust his equipment. After a brief encounter, he had witnessed the Headless Knight's immortality ā surviving without a head and possessing remarkable regenerative abilities.
Impressive as it was, the strength of its body was much greater than that of an ordinary person's, but not to the extent of being impervious to firearms. He wondered whether the creature could recover if it were blown to smithereens by a direct hit from a grenade.
He didn't have a cannon, but he did have a mini-grenade, and since the Handgun hadn't been able to break the Headless Knight's arm, maybe swapping out for a shotgun slug could merit a retest.
