章 203: I Can Tell That It Is An Indecent Card at One Glance

Qing Ming City.

At the shop.

Lu Ming was studying matters pertaining to the quality of energy.

He had been through the one to three-star stages and did not have much of an understanding of four-star. Therefore, he had never considered this matter. Having briefly gained an understanding of it from Gao Xiaoqing, he was certain that the huge depletion in energy this time was most likely due to poor energy quality!

Quality…

This was a rare term.

At the very least…

Lu Ming had not heard anyone talked about this since he started cultivating.

However, this was very normal. This was the same as not knowing about calculus when he was in primary school. Anyway, many people learned about it before they had the corresponding ability to deal with it?

If you don't believe this, you can ask Xiaobai.

"Xiaobai."

Lu Ming suddenly asked, "Do you know what is energy quality?"

"Yes."
