Hearing Arthur's statement, the Old Earl was not surprised.
Arthur and Kalal definitely had some kind of cooperation.
Otherwise, how could Kalal have charged into battle for Arthur?
Moreover, the Old Earl was very confident that Arthur had promised something like "helping Kalal become the heir to the Ainhars Territory" to Kalal.
Perhaps, it was even "directly obtaining the Ainhars Territory."
These were all things that Kalal sought after.
Only by fulfilling what Kalal sought would he choose to cooperate with Arthur.
This was basic logic.
Surely Kalal wasn't just charmed by the present Southern Lost Spirit Medium's charisma and decided to throw himself into the fray with his own provisions, right?
How could that be possible?!
Arthur Kredos was just a Southern Lost Spirit Medium, not one from the Inner Bay Golden Lion Family.
Moreover, even in the Inner Bay Golden Lion Family, aside from the Old Lion, not a single person showed a Talent similar to the "Lion Group."
