Chapter 528: Chapter 528 – Cross Reference

"No, the Equilateral Rune goes on top of the Trinominal Rune," Callen said as he pointed at two Runes inside a Magic Circle between Shang and him.

Shang rubbed the bridge of his nose in stress and started from the beginning again.

There was so much to remember and look out for!

It was like Shang had to do a complex equation while talking with someone and leading them to complete a yet unknown part of the equation.

He had to keep so many different things in mind.

He had to draw the Rune correctly, transform his Mana into just the kind of Mana he needed, precisely control the shape of his Mana, and even had to evoke certain emotions sometimes.

It took Shang several minutes to do the calculations for the Magic Circle every time, and when he finally started to draw it, some part of the equation always slipped his mind, vanishing into the aether.
