Xiao Ruoling hesitated, "This..."
Chu Zhiyuan smiled and said, "This is a swordsmanship I developed myself; it's not from the White Cloud Sword Palace, so I can decide who to pass it to."
Xiao Ruoling still hesitated.
Chu Zhiyuan smiled and said, "If Ruoyu's swordsmanship is better, both you and I can rest assured, wouldn't that be wonderful?"
"Hehe, thank you, brother-in-law!" Xiao Ruoyu said excitedly, "What swordsmanship is it?"
"This is one of the sword techniques I've acquired, called the Surging Wave Sword Technique," Chu Zhiyuan said. "It matches well with your current mental state and aligns with your mental method. Let me demonstrate it for you."
As he said this, he began to slowly demonstrate with his sword.
The sword moves were not fast, but their momentum was imposing, one move after another, overwhelming like the overturning of mountains and seas, making it hard for one to breathe. Xiao Ruoyu watched with his eyes shining.
