Once Ku Mu left, the boy had a slightly complicated look on his face. He naturally knew of Ku Mu's personality, but no matter what, Ku Mu was a person he had invited, and he could not say anything about it, just stare at Su Ming.
The expression of the old man in purple had already become calm again. He sighed in his heart, thinking that Su Ming was, in the end, not ruthless enough, or else he would not have let Ku Mu flee.
The white-robed man swept his gaze past Su Ming. His expression was calm, and his thoughts could not be seen.
However, this was the first time they came to know Su Ming. They could only gain a superficial understanding of his personality. There was no way for them to come to know what he was really like. If there had been anyone in that cave abode who was familiar with him, they would definitely know that Ku Mu was going to die.
