Chapter 579: Defeat, the Northern Dragon King Escapes!

In another part of the blood formation, the Western Dragon King, who was arranged by Zi Yan to rescue, was quickly throwing the bound ancient dragons out of the blood formation. However, even though he was not slow, many people were still blown into blood mist.

Seeing this, Zi Yan said directly: "Great Elder Qingshan, Elder Zhunan, you go and rescue people quickly, leave this to me!"

"Yes!"

Hearing Zi Yan's shout, Qingshan and the Southern Dragon King quickly flashed, left the battlefield, and rushed to the blood formation below.

At this moment, there were about 700 ancient dragons who still had breath in this blood formation.

After Qingshan and the Southern Dragon King joined the rescue, thirty or forty ancient dragons who were bound by blood were rescued and thrown out of the Dragon Transformation Demon Formation.

"Hehe, the Dragon Transformation Array is the supreme skill of my ancient dragon clan. Those rubbish actually want to destroy it. They are really stupid!"

At this moment, looking at the huge blood dragon in the sky, the ferocious face of the North Dragon King was fierce. He looked at Zi Yan not far ahead with a resentful look, and his figure rose directly, and finally turned into a blood light and rushed into the blood dragon's huge mouth.

As the North Dragon King rushed into the blood dragon's body, the blood dragon's luster condensed again, and the dark blood light lingered on its body surface. The huge dragon scales flashed with a chilling luster, as if it were real.

"Roar!"

The blood dragon's huge pupils with endless violent blood looked at Zi Yan coldly and ruthlessly, and then the huge body slowly squirmed, and the ferocious mouth suddenly opened. A huge blood light of a hundred feet, which contained a bloody energy that changed people's color, was like a crazy roaring dragon, rushing towards Zi Yan.

"Lord Dragon King, be careful!"

Feeling the might above the sky, Qingshan's speed of rescuing people was sluggish, and his eyes were filled with strong worry.

"Be careful, Lord Dragon King!"

Blood light burst out, and the West Dragon King, the South Dragon King, and tens of thousands of ancient dragon clan strongmen outside the North Dragon Island all exclaimed. From the blood light, they felt a kind of terrifying power that made their hearts palpitate. If they were really hit head-on, they couldn't imagine what would happen.

After being surprised, the South Dragon King, the West Dragon King, Qingshan and others quickly rescued the bound strongmen again. They knew in their hearts that as long as all these people were rescued, the North Dragon King's formation would not be replenished, his injuries would not recover so quickly, and his strength would not continue to improve. This is the only way to help Zi Yan now.

"Go to hell! Our Lord Dragon King!"

Looking at the blood light that pierced through the void, the North Dragon King's proud roar also resounded in this void space.

Facing the roar of the North Dragon King, Zi Yan's eyes, which were glowing with purple light, were filled with a look of determination.

The next moment, she raised the golden sword high above her head with both hands, and a strange power flowed from her body into the sword.

"Let's end it!"

Zi Yan shouted in her heart, and the golden sword in her hand slashed down fiercely in the direction of the blood light.

At the moment when the sword was drawn, nearly one-fifth of Zi Yan's purple hair suddenly turned gray. Obviously, Zi Yan had overdrawn a lot of vitality in this attack.

The next moment, what made everyone's pupils shrink was that the blood light, which was enough to rival the peak of the four-star Dou Sheng, and even the powerful five-star Dou Sheng in the early stage, was directly split into two by the strange energy in this sword.

In the eyes of the crowd, they clearly saw that the blood light that crossed the void suddenly became empty at a rapid speed from the place where it came into contact with the sword light, and was cut in the middle without any resistance.

The speed was extremely amazing. After a while, the huge blood light was completely split into two. At this time, the strange energy in Zi Yan's sword was about to hit the huge blood dragon's head.

"Roar!"

At this moment, the dazzling blood light burst out from the blood dragon's huge body, gathered in its ferocious mouth at an amazing speed, and finally turned into a half-foot-sized, dark-colored solid blood bead. The surface of the blood bead was covered with blood lines like blood vessels, and an extremely bloody smell filled this empty space.

"Swish!"

As soon as the blood bead appeared, the North Dragon King's eyes were full of madness, and he directly sprayed it fiercely at the sword energy condensed by the strange energy in front of him. As the blood bead left the body, the blood dragon immediately began to collapse, as if all his energy was taken away by the blood bead.

"Dragon Soul Pearl, this beast, he didn't even spare the souls of his people!" Seeing the blood-colored pearl, the ancient dragons outside the blood formation suddenly had bloodshot eyes. This Northern Dragon King not only devoured the flesh and blood of his people, but now he didn't even spare their souls.

Under their gaze, the huge blood pearl blocked the Northern Dragon King, but cracks appeared in an instant.

Obviously, although the blood pearl was powerful, it was still no match for Zi Yan's sword that overdrew a lot of vitality.

Soon, the blood pearl was also cut in half, and endless blood energy spread from the blood pearl.

However, although the blood pearl was cut open, the power of Zi Yan's sword was almost offset at this moment.

After the giant blood dragon dissipated, the Northern Dragon King reappeared, but this time, he had no intention of fighting any more, because the few hundred ancient dragon clan warriors left in the Dragon Transformation Demon Formation below had been rescued, and the Dragon Transformation Demon Formation had no energy to supply him. His injuries were extremely serious, and if he dragged on, he would definitely die here today.

"Hehe, Lord Dragon King, although I lost today, you are not much better. When I return to the Dragon Clan next time, it will be my turn to sit on the throne of the Dragon King!"

The Northern Dragon King roared at Zi Yan, and then, dragging his body, he directly tore open a huge space crack of a hundred feet on the spot, and then drilled in without hesitation.

With the strength of the Northern Dragon King, it was impossible for anyone present to set up a space blockade that he could not break through, and at this time, Zi Yan was basically unable to send out such a powerful sword as before.

Looking at the fleeing figure of the North Dragon King, Qingshan and the Southwest Dragon King quickly launched a fierce attack on the space crack after saving everyone.

Zi Yan did not chase him. At this time, the golden sword in her hand, which seemed to be formed by liquid, slowly fluctuated and then dissipated into nothingness. When the dragon-slaying sword dissipated, a mouthful of blood spurted out of Zi Yan's mouth, and her body slowly fell backwards.
