Lin Mu didn't know what to truly think about the artifact spirit in front of him.
On some level she was possibly one of the strongest beings he had met so far and at the same time she might have the youngest mentality of them all. If it weren't for the fact that the Deep Sapphire City had restriction that only allowed Haima and trusted people inside, it wouldn't be out of the norm for someone to take advantage of her.
Lin Mu had already seen something like this before in the Memoirs of the Lost Immortal. But that was an even greater danger than this. The memoirs didn't mention it in detail, but it talked about a great sword that was the size of a sky-piercing mountain.
The sword was something many people knew of and was considered to be an ancient artifact that many people visited in hopes of obtaining some fortune. The Lost Immortal was one such person too and even gained some insights from it.
