Alex's first time contacting a spirit guardian was in his awakening ceremony. There he met the spirit of the primordial ether. A spirit guardian he inherited from his father. And due to that, he got the skill, of asynchronous energy circulation.
And now the hint that his energy circulation method could be improved shook Alex from the core. After all, he felt his accumulation of energy slowing down to a halt for the past couple of days.
If he improved at the past rate, it would have taken him years before he finally reach the peak of Tire 3 Warrior. But now, he could feel the enhancement.
Even though he still doesn't know what asynchronous energy circulation is, it seems to be important to his growth.
And the other mystery that the farm could somehow extract data whenever he makes contact with supernatural entities called spirit guardians excited Alex.
He now knows how to increase his strength faster.
