Chen Mu was unaware of the fright Luan Qiumei and Xia Yu'r had experienced.
If he had been there and seen Xia Yu'r's "Reversing Yin Yang" technique, he would have been amazed and would have admired it, trying to learn a thing or two. After all, the Yin Yang Domain was able to reverse the natural transformations within a certain range, and his Qiankun Path could similarly "reverse Qiankun," making all techniques in the world learnable for him.
As for the fact that Xia Yu'r and the others only knew about Ji Yuanshan's death and were not sure that it was him who had killed Ji Yuanshan, he wouldn't care either. Even if they knew, it wouldn't matter to him at this point. Killing Ji Yuanshan was not a big deal to him, and there was already no room for easing tensions with the Mysterious Mechanism Pavilion.
After killing Ji Yuanshan and the other two, Chen Mu had only acquired three Spirit Weapons.
