The Destiny Faction's mysterious substance was something he simply didn't have on hand; these three were transcribed using pure substances, so realistically, selling Destiny Faction's supernatural knowledge on a large scale in the short term was far-fetched.
The channels of the Silver Dragon Trade Association were extensive, yet they were uniquely unable to purchase the Destiny Faction's mysterious substance, seemingly because its quantity was too scant.
For other mysterious substances that Chen Lun acquired from the Silver Dragon Trade Association, he almost always paid a premium. The market price for a unit of mysterious substance was around 50 gold pounds, and he spent 60 per unit.
Fortunately, after transcribing them into supernatural knowledge and reselling them to players, the profits increased tenfold, if not more—definitely a lucrative business.
Chen Lun never tired of it.
