Levi's heart skipped a beat. He had seen the name Grimm Walter on the label of the Concentration Potion he had obtained from killing Syrcus.
From the looks of it, Grimm Walter possessed the potion formula Levi needed. However, the former was only selling the potion, not the formula.
Levi watched the people continue to bid and finally left the auction hall silently. When he left, he sent a voice transmission to the beautiful staff member without batting an eyelid. "I have a breakthrough potion. Please help me contact Mr. Grimm."
He didn't declare it out loud. He didn't want to reveal his wealth. He would keep something as precious as the breakthrough potion a secret for as long as possible. There were so many wizards here. Although they were all bound by legal restrictions, some crazy people might take risks. Levi didn't want to be targeted by so many potential enemies just because he wanted to buy a potion formula.
