Ye Feng nodded, his expression as still as an ancient well. He walked towards the bookshelf, not flipping through the books himself but releasing his spiritual power to scan through them directly.
Soon, a slight change crossed his face. Although he had seen most of these cultivation techniques and secret manuals on the exchange list before, there were still a small part that he hadn't.
He quickly pulled out a secret manual with "Xuanbing Nine Weights" written in large characters on the cover and immediately began to read it.
"Indeed, the real treasures will not be casually put out for exchange," Ye Feng couldn't help but lament after finishing the introduction.
"Isn't that a very normal thing? Would you casually exchange your family treasures with others?" Gu Ao Duo's voice came from beside him.
Ye Feng thought there was some truth in these words, so he nodded and directly asked, "Then, Lord Gu Ao Duo, what type of martial arts do you think would be suitable for me to pick?"
