When the Lord received the news, he was stunned, unable to believe Logan's words were true. A Grand Elder who had entered the Dominator Realm and stood above everyone else was actually slain?
He couldn't believe it, yet had no choice but to believe since Logan had no reason to deceive him. Moreover, the First Family's Patriarch had genuinely contacted him and planned to have a meeting early the next day, presumably, to discuss cooperation.
It was known that Logan was only in the Mythical Realm, and the fact that he could cause the demise of someone in the Dominator Realm was unbelievable - the gap between their realms was worlds apart.
Even though Logan might not have done the deed himself, it was all due to his cunning plan that played both major factions like a fiddle. When the Lord found out that the Grand Elder was hunting Logan, he even considered going to save Logan himself but couldn't leave the Million Zhang Territory unguarded for a day, as chaos would surely break out.
