Lux waited until night time to take out all the Beast Cores in his possession.
He had 6 Argonaut-Ranked Beast Cores, 17 Deimos-Ranked Beast Cores, 36 Rank 5 Beast Cores, and 220 Rank 4 Beast Cores in his possession.
In order to create a miracle, Lux sacrificed all the corpses of the Insects on the battlefield, in order to give birth to ALL-MITE.
Because of this, the strongest member of Lux's Necromancer Covenant had become a Ranker, which allowed them to overturn their helpless situation.
As for the Rank 3 and below Beast Cores, Lux gave them to Pietro, so that the Mayor of Abingdon Town could exchange them for gold in order to help the survivors start anew. Many children had lost their parents, and had become orphans due to the incident that happened several days ago.
