The Void Stones placed here by Master Jiu Tong are indeed the lowest grade, essentially bordering on "scrap" material.
Just think about it, what kind of Void Stone could you possibly buy for ten medium Spirit Stones?
Master Jiu Tong insists that the more valuable Void Stones won't be sold here, "... There's a hidden Teleportation Formation inside, which can transport to a location near the headquarters. Valued clients willing to give a deposit of ten upper Spirit Stones can find me through the Teleportation Formation."
Are you really afraid of this danger? Feng Jun finds the development of things somewhat absurd, but it's clear that these Tianqin Natives have a much more precise assessment of danger than he does, "Looks like I've introduced you to a dangerous business?"
"Dangerous... what does that count for? I quite like it," Master Jiu Tong thinks otherwise, smiling slightly, "As a cultivator, I only worry about being mediocre, not about danger!"
