Lex had a personal motive behind urging River and Pearl to hurry up - one besides planning his revenge, although it wouldn't clash with that. If he spent decades or centuries within the Land of a Hundred River, wouldn't he be an old man by the time he faced Daekol?
Although, being an Immortal, he didn't really age, and he could live forever, mental age was still a thing! He didn't want to be a geezer when he returned!
Lex could not help but sigh. Time was unrelenting and unforgiving, treating all equally. Fortunately, he did not need to care about how unforgiving Time was.
He left only a small part of his mind to focus on the young couple, and finally began to work on his own plan. The items and ingredients that he was requesting for the quests were not useless.
