章 1609: Chapter 1609: Need Ten Thousand... Merit Points

"What types do you have?" Lin Caisang asked.

"Master, after synthesizing your requirements, I believe there is one type of jade book that is extremely suitable," Caique pondered for a moment, then said.

"This kind of jade book can be taken out of the Jinzhu Space, and it can hold a very large number of characters. Moreover, it can accommodate several different kinds of knowledge at the same time. Of course, the most important thing is that it can be attached to the human body, becoming invisible at will, and can be opened at any time."

"I want this one."

Without a second thought, Lin Caisang immediately said.

That way, anybody who wanted to get what she gave Lin Chushui would find it impossible, which could not be more convenient.

"Master, to exchange for such a jade book, you will need ten thousand... achievement points," Caique said.

Lin Caisang: "!!!"

Ten thousand achievement points, isn't that too much?

"What did you say, dare to repeat that?"
