Once one week of rest was up, they picked up several missions, spending half of the month on a mission and another half to absorb the cores.
Of course, Nathan received the remaining mature class cores from Evelyn. In addition to the rest of the cores, he managed to increase the Ena of Anubis and Nidhogg to 10,000.
Still, due to the amount of cores he received from the mission with Flora, he actually surpassed his original goal.
It might not be by a large margin. In fact, he might have gotten a lot more had he saved his Ena instead of summoning his fourth familiar. However, it didn't matter much to him. He had made a decision he wouldn't regret.
As a result, all his familiars now had 10,000 Ena each. In addition, his own Ena had surpassed 12,000.
He knew that Alavenya was most likely to be stronger. In fact, her familiars might have at least twice the amount of Ena of his familiars, while Alavenya might have several times his Ena.
