Regarding the Yellow Heaven Domain, Li Ji'an had already gained a detailed understanding during the Two Domains' invasion of the Celestial Cyan Domain back in the day.
His first choice back then was not actually the Ten Thousand Merchants Domain, but rather the Yellow Heaven Domain.
Though the Yellow Heaven Domain, like the Boundless Domain, was called a Demon Domain, it had a significant difference from the Boundless Domain.
One of the main reasons was the difference in geography.
The Yellow Heaven Domain was several times larger than the Celestial Cyan Domain and the Boundless Domain, with its vast territory encompassing grasslands, deserts, glaciers, and snow-capped mountains.
However, the distribution of Spirit Veins within it was especially scattered, and one might need to travel hundreds of thousands of miles to find a Spirit Vein Area.
The Domain had never truly been unified, and not even a loose form of governance like in the Boundless Domain was possible.
