"What a pity..."
Duan Bo's heart was filled with regret.
"Duan Bo, I thought I saw my sister just now," Lin Xin suddenly asked.
"Miss Yaoyang was accompanying important guests, she just happened to pass by here temporarily," Duan Bo replied with a smile.
"I heard that you're the Chief Instructor for the Secret Blood practitioners?"
Lin Xin suddenly asked again.
"Yes... Young Master, what would you like to say?" Duan Bo was somewhat curious; he couldn't quite guess what was going through the mind of this child, Lin Xin.
"Can those who practice the Full and Waning Sword Technique invoke the Heaven and Earth's Elemental Energy?" Lin Xin asked in a low voice.
"They cannot; that is a sword technique with a different purpose," Duan Bo shook his head.
"Later, can you let me witness the power of the Full and Waning Sword Technique?" Lin Xin narrowed his eyes, revealing a mature and serious expression.
