The girl in black had earned over eight million gold coins from Tang Zhen just by helping him appraise it. Even after a 20% discount, it was still over six million.
Of course, the other party earned money through his own ability. Moreover, the price was clearly marked. The creation balls that he helped Tang Zhen choose were also the best of the best.
Just based on this point, he had a clear conscience when he took the money.
To an ordinary person, 6000000 gold was an astronomical figure. To an artisan, however, it might not even be enough to cover the cost of a single research.
The girl in black might have been used to this amount of gold coins, so even though she had a huge amount of money, her expression did not change, and her speech and behavior did not change at all.
As for the appraisal price of 800000 for the next pill, Tang Zhen similarly didn't care. With his status, the gold coins in this world were no different from dung.
