The pair from the Serene Glass Valley had originally thought to struggle till the end. But after seeing Lin Mu's abilities they decided against it. Instead, they chose to lose the battle honorably.
But before that, the two hoped to talk with Lin Mu a little. At the very least, they wished to get acquainted with him. After all, Lin Mu seemed to be a Second tribulation Stage immortal on the outside.
There weren't many cultivators like this that could battle a pair of Fourth Tribulation Stage immortal and a Third Tribulation Stage immortal like this and defeat them. Thus they at least wanted to get to know such a capable person.
Even if Lin Mu might have been assisted by another cultivator and a beast, it still didn't change the fact that he was the one who had blocked their combined attack.
