As an intermediary, one must make a profit margin.
The price Noland Lee sold to the Pure Light Court was around 400 million gold coins for each Magic Scroll.
By the time the Pure Light Court resells the sealed Thunderclouds to the Wizard Advancement Association, the price might reach 1 billion or even 1.5 billion.
Calculating like this, is Noland Lee at a staggering loss?
Wouldn't it be better for him to directly sell the Magic Scrolls to the Wizard Advancement Association?
Noland Lee contemplated deeply and chose not to do so.
He is a person who dislikes trouble.
If the Wizard Advancement Association were to find out that Noland Lee had Wild Magic in his possession, then the one to be put on the experimentation table would not be the Thunderclouds, but Noland Lee himself.
Having the Pure Light Court act as an intermediary indeed meant Noland Lee would lose a portion of his profit, but it also protected him, preventing the Wizard Advancement Association from discovering him.
