"Seize Them"

As a potion maniac, how could Harry let these potions go without experimenting with it? 

And since he's sure that even the headquarters had never produced such potions…

If the Roane branch Alchemist Guild could monopolise the potion, wouldn't the headquarters allow them to hold an auction in the region? 

That means the Roane branch guild's status would rise significantly in the alchemist society! 

When Harry thought about this, his eyes turned slightly green. He didn't show anything on his face, but his heart was beating fast as he cleared his throat. 

"Lady Sloan, we can't determine the potion's type and its effect. If you want to get licenses for these potions, you have to leave the potions to us so that we can test their authenticity." 

When Harry said this, he glanced at the five alchemists behind him and nodded. 

The five alchemists were young, but they're not idiots.
