Kyran did not elaborate. However, he had two reasons for being thankful to Osric.
First was because Osric inadvertedly confirmed Neo's status.
Although Kyran used the durable materials he could acquire during his stay in the Tower of Tribulations when creating his puppets, he was still worried if it was enough to withstand a Legendary mage's magic attack and pressure. So far, he only had himself to test his puppet's durability. However, he knew deep down that he had held back his strength because it pained him to see such rare materials destroyed.
The way Osric praised Neo— Kyran was positive he was talking about the latter— it confirmed that Neo's body was still intact if the former still considered him a 'young man.'
As for the second reason...
"I have come as you ordered, master."
A powerful male voice spoke from behind Osric.
Kyran smiled as he looked at the person who had just arrived.
The newcomer was none other than Tritus.
