Importance of Spiritual Roots

"Improve the Earth Spiritual root?" Alex asked, not sure if he heard her correctly.

"Yes," Liang Qiu said. "It will improve the Earth spiritual root of a person."

"Can it turn a lesser spiritual root into a superior one?" Alex asked with a curious look on his face.

Han Daiyu chuckled a little when she heard that, while Liang Qiu simply sighed.

"It seems alchemist Yu does not know about spiritual roots then. Given your capabilities, I would have expected you to know a lot about it," Liang Qiu said.

"I'm sorry?" Alex looked confused. What was he wrong about?

"Don't be," Liang Qiu said. "It's not just you. Most of the world is also unaware of this fact. We only came to learn it about a thousand years ago from the meteor shower."

"You see, people think there are two types of people. Those who have bad spiritual roots, and those who have good spiritual roots."
