Magic Circles!

Etheria's room, Mozard Empire,

Kaen, sitting in a close-legged position, began his magic training.

He, gathering mana from the atmosphere, guided it into his body before letting it reach his new Dragon Heart.

The mana started to Invade Kaen's body, however, it was sucked by the mana hole that Kaen had in his Solar Plexus.

This mana hole was what allowed Kaen to use aura.

Every aura knight had one located at their Solar Plexus.

However, To create Magic Circles around his heart, Kaen had to separate the two types of mana —— the mana from the mana hole and the mana he was planning to use to create Magic Circles.

Here, the Technique that Kaen had acquired with Yuriel, came in handy —— The Magic Circle Formation Routine.

This technique mentioned the exact way to absorb mana from the atmosphere while not allowing the mana hole to suck that mana inside.
