Tan Yu's gaze turned to the mountains, discovering that the vein of Green Crystal Stone had mysteriously disappeared. No matter how he employed his Soul Power to probe, he couldn't find a trace of it.
Instantly, Tan Yu gritted his teeth in anger, secretly acknowledging Lin Chen's impressive methods. This Concealment Formation was not something an average Formation Master could achieve.
Now, the entire Green Crystal Stone vein had vanished before his eyes, and despite Tan Yu's various efforts, he could not discern it, making his fists clench tightly in frustration.
"Lin Chen, mark my words, I've noted this debt, and I won't let you off easily."
At this moment, with the entire Green Crystal Stone vein disappearing, Tan Yu couldn't even locate the vein, let alone mine it.
