Xu Yi was startled, looking at Xiao Mu, "How...how did you know?"
"Grandfather, does your strength truly diminish every day?"
Xu Zi was equally taken aback. But seeing Xu Yi's expression, he knew there was no need for his grandfather to answer, what Xiao Mu had said was true.
Looking at Xiao Mu, he anxiously said, "Please enlighten us, Mr. Xiao, what happened to my grandfather?"
Xiao Mu said, "The old man doesn't cultivate secret arts, so he can't perceive his own situation."
"However, I can see that the flow of luck around the old man is diminishing every moment, but the loss is so slight that one can hardly notice it."
Xu Yi laughed bitterly, "I thought it was because I was getting old that my strength could not improve, but it turns out it's because of the loss of luck. Mr. Xiao, do you happen to know how I can solve this? Is there any way to prevent the loss of luck?"
"I happen to have a way to prevent the loss of luck, but it may not solve the root problem."
