"Master Gu, how did you figure it out?"
Master Gu picked up some stone debris, examined it carefully for a moment, and nodded, "These stone fragments are half old and half new, carrying a stale scent, and these chiseling marks... Around Solitary Mountain, Mining Cultivators use pickaxes and other Spiritual Artifacts for mining, and the refinery shops are all too familiar with them. A normal mining pickaxe could never leave such marks on stone."
"These marks are left by Spiritual Artifacts used for tomb raiding."
Master Gu reminisced for a moment, then continued, "Years ago, when I was learning to refine artifacts, I met several fellow travelers and got along well with them. While drinking and chatting, I heard some secrets and found out... they made tomb raiding Spiritual Artifacts for the tomb robbers."
Mo Hua's expression was somewhat peculiar, "Wouldn't the Taoist Court cause trouble for them?"
