"Grandpa, I…" His grandson stared at the Grey-robed Old Man in astonishment and said.
The Grey-robed Old Man looked at the Sword Marks and words within the Cave Mansion and said, "The Sword Marks in this Cave Mansion are the moves of my Sword Skill, and the words in this Cave Mansion are the mental method of my Sword Skill!"
"You've spent seventy-two years in Cultivation, and now you've already cultivated it to the Great Achievement Realm. Do you mean you don't know that?"
The Grey-robed Old Man said with a smile.
