This was akin to Lu Yang's side providing only the barbecue rack and the kindling flames, letting the Nine Nether Sect run the restaurant, and thereby obtaining sixty percent of the profits.
The Fifth Elder never expected Lu Yang to dare to operate in such a way.
This earned them far more money than when they were young and following Old Nine to sell "Wish Granting Technique: Local Version"!
There always comes a thriving new generation ahead of the old, flourishing ever brighter than its predecessor.
Lu Yang was not afraid that the Nine Nether Sect could break the Elder's prohibition, or replicate the kindling flames and throw them away to operate on their own.
