Because there was no normal firearm capable of withstanding the recoil of such a bullet, without spiritual power to dampen it, the gun would certainly explode with just one shot.
This pistol, like the white Browning pistol that Qiuyang Qiu Yang had given him, was a product of a combination of the power of immortality and technology.
But the design philosophies of the two were completely different.
However, if one were to argue which developmental direction was more rational, it would be difficult to compare.
If one had to compare their strengths and weaknesses, the spiritual power pistol designed by Qiuyang Qiu Yang would definitely pack a greater punch with each round.
