Aur sank into deep thought, sitting cross-legged in one of the ready-made caves he had just constructed with his bare arms.
His brows furrowed as he peered into his mental space. The spells there were all rotating around his vital spell.
The pale blue mana covered almost fifty percent of his entire mental space already.
The main problem was that there were too many spells, including the ones he had acquired from the Alchemist Elmer, the peak tier one wizards, and the head Elder.
In total, he had accumulated twenty-three spells. However, this wasn't advantageous; instead, the walls of his mental space started to crumble under the pressure of these countless spells.
As a mid-grade mental space, he simply couldn't hold so many spells.
"I need to discard some of these spells," he decided, with a decisive glint in his eyes. He summoned his system.
"Muscle System."
As the blue panel appeared in front of him, Aur focused on the spell category, and instantly all the spells he had were shown in another panel that appeared in front of him.
After the panel appeared, Aur wore a thoughtful expression as he willed it to change, showing the recently acquired spells he had gained.
There were many spells like plant nurturing, fireball, water ball, wind slash, earth wall, etc.
These were all common spells, and their strength wasn't too great.
Therefore, he skipped these common spells and looked at the more unique ones.
Flame Manipulation and Spirit Nurturing.
These two particular spells caught his eyes. Except for these two, the others weren't particularly strong.
Flame Manipulation spell was stolen from the corpse of one of the ten wizards, and the other was from the Alchemist Elmer himself.
"These should do." Then Aur's eyes darted to the last spell, which was the one he had taken from the head elder.
Looking at the section, his eyes revealed a glint of surprise.
- Metal Escape (tier two)
Unexpectedly, Aur had gained a tier two spell from the head guard; this was his first tier two spell.
"No wonder why the mental space was so burdened," Aur thought as he focused on the spell, and a new panel appeared in front of him again.
"Fourteen spells is plenty. If there is the addition of even one more spell, my mental space would again become unstable, which is counterproductive."
The larger the mental space, the more stable it is, so those with a higher grade of mental space are able to store countless spells.
For Aur, it was already a miracle that he could store thirteen tier one and one tier two spells already.
Checking his mental space again, Aur muttered, "it is time to break through to the high-tier one wizard realm."
With that said, he fell into a deep meditation after taking out two high-grade mana crystals and holding them in his two hands, focusing on the pale blue mana that filled half of his mental space.
The calm pale blue mana sea began to stir and produce waves like a sea crashing against the walls of his mental space under Aur's will.
The breakthrough was extremely smooth this time, with the walls of his mental space soon cracking like cobwebs.
The suction force increased to a terrifying amount; the moment the walls of his mental space were broken.
If he let go of all his mana, the entire foundation of his mental space would be shattered, leaving him crippled without a mental space or, in the worst case, causing his death.
With powerful control, Aur gradually nurtured the walls of his mental space using the pale blue mana, making them sturdier.
Just like that, an hour passed.
Aur snapped open his crimson eyes.
"I succeeded," he exclaimed.
Some of the pale blue mana still lingered in the mental space. For that, he needed to expend it before refining new and stronger mana, blue mana.
If pale blue mana could be said to be a refined form, derived from his mental space, then blue mana was the more concentrated and potent form, with a stronger essence.
This wasn't just a difference in colour, but instead, the essence had changed, and the power of it had increased in roughly a five-to-one ratio.
That means one drop of blue mana could be comparable to five drops of pale blue mana.
Aur used the remaining mana in the most imposing spell in his mental space: the tier two Metal Escape spell.
His body instantly turned into a silver light, but that lasted for less than a breath before he returned to normal.
"There was at least five percent of my pale blue mana still left in my mental space, but it couldn't even last me for a breath of time," Aur shook his head, as he had expected.
Even if he could use the tier two spell with his new blue mana, the duration wouldn't be long, and just like when he was a wizard apprentice, the power would be less than one-tenth.
