Erix Rin, Isabella, Lily, and Aria farmed resources and used them without any breaks for a bit over a day, spending a total of 27 hours and reaching the peak stats in the Magic source.
But after they reached the peak in stats, they encountered a little bit of trouble.
The group sat cross-legged under the big tree on the mountain peak, their aura volatile and unstable.
Everyone was focused and stabilizing their magic source. They gained too much Magic Power from different sources constantly and gained power fast, so their magic source's foundation was no longer solid.
For now, they were just using Prana and controlling it basically as indicated by constantly changing elemental phenomena in the sky above them.
Of course, doing this was also a bit harder as they were occasionally losing control over Prana, but this was not uncommon.
