The Lord of Devouring Souls: My Iron Chain Can Cultivate Immortality

Traveling through fantasy and troubled times, I only have one copper plate left in my hand. I wanted to exchange it for a pistol to protect myself, but the system prompted: The suppression of the laws of the low-spirited world was detected, and all modern weapons became ineffective.

A gang war broke out in the city, and my chain swept across the place. The hall leader was shocked: "What kind of skill are you doing?" I was about to explain when the chain suddenly wrapped around the hall master: "Ding, a spiritual item was detected nearby. Do you want to exchange it?" The hall master's face changed drastically: "You, you stole my spirit stone?"
