Demonic Abyss

The Demonic Abyss is the 'Martial Field', and the Young Sovereigns sent here were the most outstanding ones. The Demonic Abyss resembled the Alien Battlefield greatly, both its terrain and its sky. These two elements conveyed a stifling feeling.

The Demonic Abyss was the defeated Demons’ tomb. The other races forced the Demon into the abyss, thinking that would resolve the problem once and for all. However, the abyss turned into a farm, where dreadful Demons were born. Fortunately, the Goddess of Empyrean appeared at that time. She suppressed the Demonic Abyss. She turned it into a World of Meson and sealed it off with the, Divine Chain to Tie Demon.

The Demonic Abyss has nine layers in all. From one to nine, the lower the layer is, the stronger the demons there. There is a difference between the number and power of demonic beings present in every layer. The Demonic Abyss is used to train, and, if you want to enter the next floor, every person must kill a certain number of demonic beings. Every floor of the Demonic Abyss had an oval shape, while the expanse of every floor was smaller than the one above it and the tunnels between them were at the centre. The first layer’s demonic beings could only be reluctantly considered beings at the martial-grade, while the second and third layers are quite unstable, and the fate of a Martial Emperor or a Martial Saint that ventured there will depend entirely on his luck. The most thorny aspect about demonic beings is that it’s difficult to guard against them, as their means constantly changed, while they still traveled in groups. The demonic beings were different than the blood demons and true demons one would see in the Alien Battlefield, it would seem as if they had gone through a certain mutation. They were formed by numerous demons’ energies, hatred, and rage. They had extremely strong vital energies. And the constitution of their bodies was different. Which made it difficult to kill them. The demonic beings were born in the Demonic Abyss, and their power and grade were decided the moment they were born. However, this didn’t mean that demons couldn’t raise their grades. It was extremely difficult to do, and anyone who could achieve it was extremely powerful. The demons who achieved a grade promotion would have the word great added to their titles, like the Great Earth Demon, Great Celestial Demon, etc. They weren’t obviously any Great Human Demons because the lowest grade for demons was the human grade.

Demon Lords were too strong. It was too difficult to kill all of them. As a result, the Goddess chose to suppress and imprison them here, so that they could be eliminated gradually over time. Demons can be compared to the Divine Race. They're as great as they are. Their paramount demon methods are downward compatible. All races can practice them.
