章 717: Chapter 717 – Not a Mage

"How many times do I have to tell you?! You can't just use a retrograde wall rune near a spontaneous fountain rune!"

"It works, doesn't it?"

"Yeah, sure, but you have to come up with a completely new diagram every time you want to make a new one if you keep randomly throwing things together!"

"So what? Then, I'll do just that. It's not like I haven't been doing that until now!"

Two men and a woman were sitting inside a deep and dark cave. A Peak Ancestral Beast looking like a centipede was just a couple of kilometers deeper in the cave, but it didn't attack them.

The cave was filled with thick Darkness Mana, but the three people sitting in the cave weren't paying the Darkness Mana nor the beast much attention.

They were far more focused on criticizing one guy's Spells.
