All the demons were silent as they looked in horror at the figure that shot into the sky. The terrifying aura was clearly that of a human King in the Qiyao Realm.
The human army was excited. Another King had arrived, and there was hope in protecting the human territory.
"Human King! How dare you attack my subordinates while being a mere King!" Suddenly, a cold snort exploded like thunder.
The next moment, in the sky above the countless demonic beasts, a cloud that covered a radius of dozens of miles suddenly appeared. The figure of a huge demonic beast could be vaguely seen. The long and soft figure was covered in huge black scales. It meandered in the cloud, and only two huge red flames poked out. When they were clearly seen, the huge red flames were a pair of eyes.
A huge head peeked out from the clouds. When the million-strong army guarding Zhenyao City saw the head of the demonic beast, they were stunned and felt an unparalleled pressure as if a mountain was on them.
It was a huge flood dragon. Its faintly visible body was thousands of feet long, covered with black dragon scales that reflected a dark light and emitted boundless demonic energy.
It was as if it made everyone feel despair by just standing there.
The Demon King, the Black Flood Dragon King!
The Demon King of the Demon Valley!
"What strong demonic energy! This Demon King is at least above level six of the Qiyao Realm, or even stronger!" Even a human King like the 9th Prince was solemn.
"This is the Black Flood Dragon King, one of the five Demon Kings of the Demon Valley," The Taiyi Holy Lord said in a deep voice, "It's very powerful, and it has the bloodline of a true dragon. Even a King that is the Holy Lord of a Holy Land can't do anything to him."
Demons had stronger bodies than humans, let alone the Black Flood Dragon King, who had the blood of a true dragon flowing through its veins. It was a King among the demons and was even more terrifying.
Back then, the Taiyi Holy Lord had been severely injured because he had fought against this Black Flood Dragon King. It was only with the help of a secret technique that he had managed to injure the Demon King and escape.
Everyone was on guard. Only Qin Chen remained calm. He said to the 9th Prince, "Nine, you go. Dealing with this Demon King will be good training for you."
"Yes!"
In front of outsiders, Qin Chen and the 9th Prince naturally couldn't call each other brothers. The 9th Prince also wanted to test the results of his three years of cultivation.
The huge eyes of the Black Flood Dragon King, who was coiled up in the sky, looked at the 9th Prince, who was making a move. With a hint of cold anger, he bellowed, "Human King, how dare you attack my people? I'll kill you today!"
Although the Black Flood Dragon King was extremely huge at hundreds of meters long like a long mountain range, it was extremely agile. A claw the size of a small mountain swiped at the 9th Prince, tearing apart the void. It was a terrifying sight.
The 9th Prince snorted coldly as he drew his sword and slashed out a sharp sword light that was a hundred yards long. It gathered the laws of Heaven and Earth's sword path and clashed with the dragon claw.
The thousand-foot sword light dissipated, and the flood dragon's claw was also blocked.
The Black Flood Dragon King's huge eyes looked at the 9th Prince with a hint of surprise, but its body moved, and its huge tail swept across the army toward the 9th Prince, carrying terrifyingly vast demonic energy.
If an ordinary human King were to face it, he would probably be severely injured by the dragon tail attack.
The 9th Prince let out a roar and sent out a palm that turned into a 100-foot handprint the size of a mountain. The laws of the great path in the world quickly gathered and dissolved into the handprint, making it contain the might of the world as he shouted, "Heaven-overturning Palm Imprint!"
Venerable-grade supernormal knowledge, Heaven-overturning Palm Imprint!
This was something that Qin Chen had taught the 9th Prince in the past three years.
Even in the Great Qin Dynasty, there wasn't much supernormal knowledge of this level. If the 9th Prince, who was at level four of the Qiyao Realm, cast it, he would be able to rival a level six King.
Heaven and Earth were torn apart, and the void exploded from the collision. Waves of terrifying power tore open a 10000-feet-long abyss in the ground, completely separating the human race and the demon race.
The 9th Prince staggered backward in the air, his purlicue split open, and blood flowed from it. It was clear that even with Venerable-grade supernormal knowledge, it was not enough to deal with a Demon King like the Black Flood Dragon King.
The Black Flood Dragon King's tail trembled slightly as a few of its black scales cracked open. Traces of golden blood could also be seen. Clearly, it had been injured by the Venerable-grade supernormal knowledge as well.
Clearly, the Black Flood Dragon King did not expect that it would not be able to defeat this human King directly. Its demonic might instantly skyrocketed, and clouds quickly covered the sky. It opened its mouth and spat out a white light.
Wherever the white light passed, the void actually froze directly. It was just like the extreme power of frost.
"Dragon Breath!" The 9th Prince was very knowledgeable and could tell that this was the legendary Dragon Breath. It was an attack that only the dragon race could use, and it contained the terrifying power of the dragon race.
Although the Black Flood Dragon King was not exactly a member of the dragon race, it was still a Demon King with dragon blood flowing through its veins. As such, it was able to use Dragon Breath. With this, even the 9th Prince had a grave expression on his face, not daring to be careless.
With a loud roar, the 9th Prince formed a seal with both hands and used another Venerable-grade supernormal knowledge, Holy Light Shield!
A Holy Light Shield that was a thousand feet tall appeared in front of him. The Dragon Breath hit the Holy Light Shield, and instantly, the shield froze. In the end, it turned into an ice shield before exploding, turning into dust and dissipating in the air.
"What a terrifying Dragon Breath," The 9th Prince's expression changed slightly. Even the Holy Light Shield condensed from the laws of the world had been frozen into dust. One could imagine that if it landed on one's body, even a King would be turned into dust as well.
However, the 9th Prince knew that this Dragon Breath was not something the opponent could easily release. Thus, he wielded his divine sword and soared into the sky, taking the initiative to attack the Black Flood Dragon King again.
Boom! Boom! Boom! Boom! Boom! Boom! Boom!
The battle between two Qiyao Realm Kings was extremely terrifying.
Beams of colorful energy shot out and easily tore the ground apart. They also rushed toward both sides.
It landed on the side of the demonic beast army and killed the beasts one by one. Even a Wuxing Realm beast couldn't take it and die on the spot.
On the human side, The Taiyi Holy Lord blocked the attacks and prevented any damage.
However, seeing that the 9th Prince was dealing with the Black Flood Dragon King, he could not just sit by and do nothing. This was a great opportunity.
The Taiyi Holy Lord descended from the sky and shouted, "Taiyi Thousand Sword Technique!"
He pointed his sword and performed the peerless offensive sword technique of the Taiyi Holy Land. It was a peerless sword technique created by an ancient Sage of the Jiutian Realm tens of thousands of years ago. As soon as he pointed his sword, thousands of sharp sword lights appeared in the world in an instant and rushed madly toward the army of demonic beasts.
In an instant, tens of thousands of demonic beasts were swept by the sword lights, pierced through, and died on the spot.
This allowed the human army to let out a sigh of relief. With the two Kings taking action one after another, who knew how many demonic beasts had been killed? This greatly reduced the pressure on them.
"Lu Xuan, how dare you make a move!" The Black Flood Dragon King was furious, and it unleashed its demonic might. Not only did it attack the 9th Prince, but it also attacked the Taiyi Holy Lord. With this, it was going against two human Kings by itself.
It was too strong, and both the 9th Prince and the Taiyi Holy Lord weren't its opponents in one-on-one battles. They had to work together to fight it.
Heaven and Earth cracked. The void exploded as a terrifying battle broke out.
On the ground, although the demonic beast army had suffered countless casualties, there was still a steady stream of demonic beasts rushing out of the Demon Valley and killing the human army.
Just as the human army was about to put up a desperate fight, Qin Chen made his move. He exhaled a breath of clear air, which transformed into a meteor shower. Each meteor was huge and contained a destructive power. They fell from the sky and bombarded the demonic beast army.
Boom! Boom! Boom! Boom! Boom! Boom! Boom!
Explosions filled the sky, and the flames wreaked havoc, killing groups of demonic beasts.
