"Mr. Grimm, this opportunity only comes once," Levi said calmly.
Grimm was in a dilemma. Finally, he sighed and smiled bitterly, "Sir, you win. How about this? You don't need to pay me extra Aether Stones. You're also a pharmacist, so I suppose you have the formula for the Naga's Blessing Potion and the channels to obtain its ingredients. I hope that when you have more Naga's Blessing Potions, you will give the Grimm Tower priority to purchase them. I have two sons and three daughters who are all apprentice wizards. It's hard for me as a father..."
"Deal." Levi smiled in satisfaction. "We can establish a long-term cooperation to exchange what we need and improve together."
Levi thought, "Grimm is really fertile." Generally speaking, there was not much difference between the fertility of low-level wizards and mortals. There were not many fertility barriers.
