Old Man Mu had killed many people in his life and had suffered injuries from many sabers, but none of them had surprised him like this one.
He was not a fool and had long passed the age of reckless ignorance. He was very well aware of the dispute between Dragon King and the three siblings of the Shangguan family, therefore, it was expected that they would go on their separate ways.
Before taking any action though, he had also carefully observed that it was definitely Dragon King and Maid Lotus who was walking in the desert. What's more, he even noticed that Shangguan Hong, whom he had chosen, looked and acted like himself. Most importantly, after following Shangguan Hong for a while, he did not sense any strong Internal Breath or killing desire in this person.
