"Knowledge?"

The king frowned.

An Xiaoou nodded solemnly. "That's right. In the human world, knowledge is especially precious. Ordinary people treat knowledge and being able to take the scholarly examination as a good thing to bring glory to their ancestors. If they want to bring glory to their ancestors, they can't do without knowledge."

"Knowledge can teach people to recognize right and wrong. It can teach people to farm and make a stand. Ordinary people may seem to have nothing to do with knowledge, but that's not the case. It's knowledge that lets people know how to distinguish the changes in the weather, how the four seasons change, and how the tides rise and fall. Many branches of life can't live without knowledge. The two worlds will eventually converge into one world. Humans look weak, but because of knowledge, they can build ships to go out to sea and create all kinds of tools to make them stronger."
