Inside the Elven's Royal Castle, there were only two people in the meeting room.
"Elara, what about Zero Elea?"
King Tranduil asked Elara. At the moment when the geniuses were out to go to the Luminary Spring, King Tranduil and Elara were having a discussion.
They talked about the geniuses and their potential. Elara already knew about most of them and seemed to have an idea about their power and what they would achieve in the future.
And of course, that includes Hiro and his group which will garner a lot of attention in the future due to their insane talents.
Elara already had a list that was similar to King Tranduil's which kept a record of geniuses with very high potential.
That's when King Tranduil asked about Zero Elea, one of the people who was at the very top of his list.
With his ability to defeat Rank-S - and fight with Elenia, King Tranduil had no doubt that he would be very powerful in the future.
