Cautious Suspicion
Lin Mu observed the three cultivators, estimating their capabilities.
Two of them looked to be young, possibly in their twenties, while the last person was a man in his thirties.
Of course, this was just their appearance, and their true age was a thousand times more considering they were all immortals!
Lin Mu found that the cultivation base of the two younger looking cultivators was at the second tribulation stage of the immortal realm while the older man was at the Fourth Tribulation Stage of the immortal realm. Of course, to Lin Mu who had dealt with experts stronger than this, they weren't much.
But it still gave him an insight into how strong the Serene Glass Valley was.
"Greetings, I am Mu Lin." Lin Mu decided to take the initiative. "I was invited to the Serene Glass Valley by Shuijing Ju and Shuijing Mingzhu." He said while cupping his hands.
