Xiao Yan: Sob, Sob, I'm a Useless Husband

Both Dou Qi and Source Qi had their own ranking systems. This was for internal comparison—for example, Dou Saint-level Dou Qi versus Dou Emperor-level Dou Qi. Compared against each other, however, Dou Qi and Source Qi required an external comparison system, which Jiang Lin had tentatively defined as "energy realm."

"Energy realm: an external evaluation. For instance, we can simply use heaven, earth, mysterious, and yellow to define the relative level of energies. If Dou Qi is Mysterious-grade energy, then Source Qi is Earth-grade energy."

Jiang Lin briefly explained his definitions from his energy research to Xuan Ji, Shi Fite, and the others.

"Whether on the Origin Qi Continent or the Dou Qi Continent, there have been more or less accumulated observations regarding energy realms and energy levels. It is simply that no one has systematically explained and defined them, making them somewhat difficult to understand," Jiang Lin told everyone.

On the Dou Qi Continent, certain Imperial Clans actually understood that Source Qi was stronger than Dou Qi, but they had never systematically summarized or organized it. How exactly was it stronger? Why was it stronger? In what ways was it stronger? All of this needed to be properly researched before a relatively complete and reasonable energy system could be established.
