After creating his Divine Artifact, Thirteen returned to the real world with a smile on his face.
Although the only monster currently registered on his banner was Tiona, he believed that he would be able to fill it up at a steady rate using the resources of the Leventis Family, the Central Government, and to a certain extent, the Dvalinn Federation.
He would milk these factions for all their worth, allowing him to benefit from them greatly.
'Although some of the monsters are extremely rare like Tiona, I should still be able to fill up a quarter of my immortal army with everyone's help,' Thirteen thought before taking out a pen and writing the names of the monsters he wanted to add to his collection.
After he was done, he looked at his list and then started to list out more monsters with unique abilities.
