When Jason left Old Sadron's shop, he felt much better. He had purchased the tome and got to know one of the most powerful citizens inside the Olympus federation.
There shouldn't be a single being at the 2nd threshold of the Prismar stage in the Olympus federation because it would indicate that one had created one rotating crystal enveloping three small solidified prismarine crystals.
Through the rotating crystal, the mana stored inside the mana core would be consistently moved, circulated through the mana core, reinforcing it.
At the same time, the mana strengthened the entire body as well as the mana core's capabilities.
Jason assumed that there were only the three Overlords and at most one or two more beasts with that kind of strength.
But that was not something he could say for sure.
Furthermore, there was the possibility of a temporary world bridge manifesting every once in a while.
