Draconic kingdom

Description
The Draconic Kingdom that was situated at the center of the Beast World was the kingdom that commanded the most power. With the mythical race of dragons at the forefront, the kingdom prospered and took the lead in erecting a stronghold that withstood the test of time for multiple millenia.

In the kingdom, there were multiple floating cities where powerful dragons resided, ruling over the masses of the common beasts below them. Their power boasted such unshakable belief, that the day they fell became the most shocking thing for the beings of the Beast World to hear.

Invasion and Destruction of Draconic Kingdom. (Mentioned in chapter 81)
The invasion of demons began abruptly, with multiple Demon Kings descending down in areas not too far from the Draconic Kingdom. They were somehow equipped with all the knowledge of the Beast World as they began waging war right away, causing the battalions of Black Dragons that protected the kingdom to move against them.

The Demon Kings that led hordes of demonic forces had terrible power, using Abyss Magic and Unique Skills that stood toe to toe against the strength of dragons. The war was brutal, causing the other mythical kingdoms of beasts to activate their forces and prepare to reinforce the Draconic Kingdom.

This was when a huge change occured. The daughter of the Dragon King that was fighting in the front lines was defeated and captured. This humiliation caused the Dragon King to go mad as he prepared for a war of mutual destruction with the demons. But the demons began pulling their forces out of the kingdom at this instant, calling for a momentary truce.

They called upon the Dragon King to stop the war that was causing both sides to lose many of their forces and leveraged the life of his daughter to call for an assembly of discussion of how both sides could coexist. The Dragon King naturally knew this wasn’t possible, but his dear daughter’s life obscured his judgment. His love for her was so deep that he ignored all the wisdom and logic he had and called upon his forces to attend this assembly.

Even with love blinding him, he still didn’t act rashly and moved together with the powerful regiments of black dragons as his protection. The Assembly was set on on a grassy plain where the two forces faced one another and the leaders moved to discuss.

Of course, the only thing they faced was betrayal.

As the Dragon King was approaching the tent placed in the middle of the opposing forces, he was presented with the sight of his daughter being humiliated, and then watched as she was beheaded right after.

'''The Demon King doing this was one that hadn’t appeared in the battles previously. He had newly descended down into the ranks of Demon Kings that were present in the Beast World. He was ranked 32nd, the Demon of L.u.s.t, one of the Seven Deadly Sins, Demon King Asmodeus. With an Ultimate Skill that granted him glimpses of the future, he fought against the maddened Dragon King...and brought him down'''.

After the fall of the Dragon King, the rest of the forces fell and the demon forces claimed the Draconic Kingdom.
