"I wonder if the priest, or Mr. Wang... ahem, Officer Wang, would be interested in buying this recipe from me and selling it through the Heavenly Master Mansion's shops. You're bound to make a big profit."
Zhao Douan had two intentions with this move.
First, to make money.
The Heavenly Master Mansion had a complete sales system and, because they were in alchemy, they had access to a large amount of cheap saltpeter.
Second, to deepen the relationship with Old Wang and Jin Jian through business partnerships.
He even thought it through, willing to make less himself so he could give more benefits to the other party in order to maintain this network of connections.
Especially since the girl before him was said to be a disciple of the Heavenly Master.
If things went well, wouldn't it be extremely profitable to connect with the Old Heavenly Master in the future?
If a mere Mr. Wang could produce such fine goods, the legendary Heavenly Master Zhang didn't even need to be mentioned.
