Chu Yuan had a keen intuition for war.
The countless armies of the Celestial Empire, like locusts, swiftly advanced towards the Great Nine Nether World, and just like locusts, wherever they reached, resources were uprooted and sweeped away, leaving nothing but barren land remains.
The resources of a world are always finite.
So, to strengthen oneself, one must continuously draw from outside, conquer other powers, strengthen one's own empire, and replenish one's own world, making it even more powerful.
It was the same for Chu Yuan's Dawu. To maintain the welfare of the people in his nation, they must continuously supplement from outside.
Kill, kill, kill!
The Nine Nether Empire was also a unified power, the Nine Nether Empress commanded the entire empire's forces. Her words were the will of a large world, instantly clashing with the Celestial Empire's forces.
Spectacular yet devastating scenes unfolded.
