Kapitel 451: The Witches...

"Elder, is there a potion or a way that can increase my mental energy capacity extensively?" Felix inquired.

"There is." Lady Sphinx added calmly, "If you want it, you need to trade one of your intelligence enhancement potions."

"I am willing."

Felix didn't hesitate to accept the deal. Mental energy was a must-have for potion-concoction and also for battle purposes.

However, those intelligence enhancement potions were bonuses to help him in his path, not a necessity.

Hence, losing one wouldn't affect him much.

"Let me check my stock if I still have one lying around." A couple of seconds later, Lady Sphinx said, "I will have my servant send it to you."

Felix nodded his head and waited patiently in his room.

15 minutes later...

The maid had brought the potion and took one from Felix, concluding the deal.

Felix beamed the potion in the spatial card, having no plans to drink it now since that would affect him negatively.
