The old man from the Vaergahl Family felt relieved after seeing that the Toad Clan Leader was eventually subdued. Lucas and Grey had withdrawn their killing intent, but they didn't wear friendly smiles, after all, the Toad would definitely hold a grudge against them. There's a chance that in the future, they'd have to face the Toad once again. Until then, there was nothing to worry about. Since it had handed its soul brand to Sir Astarot, then this matter was settled.
Lucas removed the barrier he set up. Sir Astarot did the same.
Of everyone present, the one with the lowest cultivation stage and also the youngest was actually the one who somehow was able to settle the matter. Although it was purely due to trickery and Sir Astarot offering some assistance, it still didn't change the fact that Grey was a frightening figure. Being able to use a statement from Sir Astarot to seem like it was an execution order for the Toad Clan Leader is a sign of his quick-wittedness.
