At the dimly lit alley, a man in a suit stopped, holding a briefcase in his hand, squinting his eyes and thinking for a while, and then walked straight to the depths of the deep alley with determined steps. It was a huge stone. Through the big red lantern hung at the door of the store, you could vaguely see the faint dark red lines on the dark stone. There are two big golden characters on the stone - Tianxiang. It looks like it was formed naturally.
