Feng Jun's answer was quite distinctive. "Expensive is fine. It's not like I'm paying... We have to make them bleed heavily once, so they'll remember the lesson better. Besides, I don't want Spirit Stone compensation anyway."
At his level, it was no longer simply a matter of valuing Spirit Stones. If he demanded Spirit Stone compensation, it would make him seem petty and invite ridicule—so someone nearly harmed you, and paying a few Spirit Stones was enough?
As they said in the Blue Star Realm: problems that money could solve were not problems. Extending that idea: problems money could not solve were the real big problems.
Since Feng Jun did not intend to accept Spirit Stones, then—how about a Teleportation Array? "How much would a Teleportation Array like that cost?"

Labor would only cost around one hundred to eighty thousand, but if you buy the materials from Tiantong, it would come to nearly a million... The Azuresteel Sect might have the materials themselves, though. That would be another matter."
Xiaosong could not help speaking up. "This Teleportation Array can only be one-way... It is impossible to teleport directly from the Mortal World to the Cultivation World, and it must be registered under Mingsha Market."

In practice, it was not that complicated. Feng Jun only needed to register it at Mingsha Market. After all, one-way
