Even after Alister's introduction, the old man didn't know anything about how powerful a Transcendent Saint was since he didn't know that a powerhouse above the Transcendent Emperor had existed.
Or more like, only the higher-level transcendents knew about the existence of the Transcendent Saints. Those ordinary humans and low-level transcendents didn't know that there was a much more powerful existence above the Transcendent Emperor.
Due to that, the old man thought that Alister was a powerful Transcendent Emperor who earned the title of Sword Saint due to his extreme swordsmanship. After living so long, the old man had encountered countless transcendents who used a sword whether it was in real life or in the news but only a few of them could use the sword intent.
The old man already estimated that Alister was a Transcendent Emperor and for that, he was glad that such a powerful existence like Alister even bothered about the lives of ordinary humans like him.
