This is an essential medicine for traveling.
A few years ago, Mu Lin once asked Mu Yu if there was such a thing as Red Crown Crane, a deadly poison, in the world, because she couldn't find anything related to it. Mu Yu said it existed, but it had been lost for a long time. He said he had caught a glimpse of it, but it wasn't where his interest lay.
So, even Mu Lin had no idea what this Red Crown Crane was like.
Mu Lin had considered, however, that if one were to be poisoned with Red Crown Crane, it might be possible to save them by using a silver needle to prevent the poison from spreading. But without any knowledge of the poison's composition or anything else about it, it was all speculation.
At Mu Lin's words, Yan Zilei's mouth twitched slightly.
Red Crown Crane!
Truth be told, ordinary people like them might not know about many things, but they've heard of Red Crown Crane. It's supposedly so lethal that even the smallest amount can be fatal, and there's no cure for it.
