Ten days before heading out for the Academy!
Eren was seen seated in his room. He was holding the smallest, F Rank Mana Blessing from his collection in his hand while meditating.
Eren wanted to use a bigger, and better one. But the area of influence the bigger Mana Blessing would have was enough for aunt Nina to figure out its presence.
Eren concentrated and tried to take the mana inside his body through the region below his navel. The eventual outcome was realized finally.
Eren felt like a black hole had been created inside his body. All the surrounding F Rank mana that was condensed in the surrounding by the Mana Blessing was getting absorbed by that blackhole genesis.
A point of mass was created after the attraction force ended. It felt surreal and real at the same time.
Eren had an inactive F Rank mana core now in his body. It only needed primary mana pathways for him to officially enter his F Rank journey.
