This was a somewhat polished stone, and there was nothing particularly noteworthy about its surface, save for its somewhat peculiar shape, which resembled that of a bird, though only vaguely in outline.
Shitou Zhang seemed quite nervous about this stone. From the moment you took the stone from his hands, his gaze never left it.
You weighed the stone in hand, looking it over several times, and found that with normal vision, it appeared quite mundane; however, as soon as your left eye began to feel slightly warm, your complexion suddenly changed, and you couldn't help but reveal a look of surprise.
"Mu Yun, have you discovered something?" Du Xishan saw the change in your expression and quickly asked.
Nodding, you handed the stone back to Shitou Zhang and said solemnly, "Mr. Zhang, this stone is quite malevolent. I don't know why you cherish it so, but I have only one piece of advice for you: if you wish to live past fifty, find a riverside and bury this stone in the sand."
