Synthetic Mana Core

Wallace was also confused after he first learned about the Synthetic Mana Core. However, he has an Astral Core in his body which allowed him to easily grasp its function. 

His Astral Core was something he placed into his body after a painful and dangerous operation using various types of energies that he can find.

Although it is not something perfect that could equal the Celestial Beings, it is more than enough to be balanced with his Mana…

In this way, he would not be dependant on a single type of Energy which can be very useful in many situations.

Especially right now where there is something like a Magic Jammer… He even heard from Aeolia that the Lamat Stones which should've been extinct were actually something common within the deepest part of the northern continent. He just decided not to find them since these stones can destroy the Magician's society if discovered.

It is better to leave them there than to bring it to their continent.
