The next moment, a pitch-black scale flew out of the bloodthirsty Great Demon King's skull and returned to the back of Su Yehan's neck.

"Ding! Congratulations to the host for killing the eleventh-level Great Demon King, the Bloodthirsty Great Demon King, and obtaining 19.5 billion energy points!"

With the death of the Bloodthirsty Great Demon King, the prompt sound of the system sounded in Su Yehan's mind at the same time.

From the encounter between Su Yehan and the Bloodthirsty Great Demon King to the killing of each other, it was just a few breaths.

Even though Su Yehan was invincible at the same level, he could kill the Bloodthirsty Great Demon King so easily, and the Spear of Destruction and the Killing Blade were of great merit.

"Now my energy value has reached 431.5 billion points!" Su Yehan opened the attribute panel and glanced at the energy value.

Then, his powerful divine sense emanated.

After sensing it carefully, Su Yehan's wolf body turned into a black light and hurried towards the front.

Because there are several powerful auras on the left, right, and rear, coming towards here.

No matter how conceited Su Yehan was, he didn't dare to fight ten with one.

Su Yehan walked all the way forward, not daring to stop at all.

I have to say that Ten Thousand Wolf Mountain, as the holy land of the wolf clan, covers an area of tens of millions of miles, as long as Su Yehan wants to hide and hide, he will naturally not be easily discovered.

Of course, what Su Yehan didn't know was that outside the Ten Thousand Wolf Mountain, in front of the White Tiger Demon Saint, a shrunken Ten Thousand Wolf Mountain Range was floating, and among them, there were points of light moving rapidly.

The Great Array of Ten Thousand Demons shrouded the entire Ten Thousand Wolves, naturally it was not just a matter of banning it, prohibiting entry and exit.

"What a bunch of waste!" The White Tiger Demon Saint looked at the more than twenty demon kings under his command, and when he couldn't hold Su Yehan alone, his expression was extremely gloomy.

Besides, Su Yehan, after escaping from the encirclement of the big demon kings, after flying for half an hour, finally met a lone big demon king again.

Just a moment later, the system's prompt sounded in Su Yehan's mind.

"Ding! Congratulations to the host for killing the eleventh-level Great Demon King, the Cailu Great Demon King, and obtaining 20 billion energy points!"

"Where is the wolf demon!"

"Where to go!"

"Death!"

"Haha, look at you running away!"

However, at this moment, a series of four powerful auras suddenly appeared around Su Yehan.

The four Great Demon Kings blocked the surroundings, making it impossible for Desu Yehan to escape, and more Great Demon Kings were also hurrying towards here.

Looking at it, the basic information of the four great demon kings emerged.

The Great Demon King of the Earth Dragon has a trace of bloodline of the first Earth Dragon in heaven and earth.

The Thousand-Footed Great Demon King is cultivated by a thousand-year-old centipede, and his body contains severe poison.

The Great Demon King of the Poison Toad has a trace of the blood of the ancient god toad in his body!

The Great Demon King of the Heavenly Crane is cultivated by a thousand-year-old white crane!

"Hmph, it's up to you, but I can't help Lao Tzu!" Su Yehan glanced at him, even in the face of the four great demon kings, he was completely fearless, and said proudly: "Since you can't go, then don't go!"

As soon as Su Yehan's voice fell, he suddenly made a move, his current energy value has reached more than 450 billion points, as long as he kills these four great demon kings, he will definitely be able to evolve again.

The Killing Eye flickered, and the terrifying light of destruction from the Dark Underworld headed towards the Earth Dragon Great Demon King.

His eyes flashed, and with two clanging sounds, two wolf-shaped blades came out, heading towards the Great Demon King of Poison Toad.

The Spear of Destruction suddenly appeared behind the Great Demon King of the Heavenly Crane and slashed it directly.

The Killing Blade hummed and headed towards the Thousand-Footed Demon King.

"How daring!"

Seeing this, the four Great Demon Kings shouted angrily, or quickly dodged, and obtained the release of divine power to resist Su Yehan's attack.

"An earthworm can also be called a dragon, then I will kill you first!" Su Yehan's eyes were cold, he looked at the Earth Dragon Great Demon King, and then, his eyes flashed, and with two clanging sounds, two wolf-shaped blades were sent out, and he hurried towards the Earth Dragon Great Demon King.

The Earth Dragon Great Demon King naturally did not dare to resist in the face of the rapidly coming Silent Void Yuan Slash, and the next moment, a rumbling sound came, and an earthen wall suddenly appeared, resisting the Silent Void Yuan Slash.

"Spear of Destruction, Blade of Killing, Slash!"

But just when the Earth Dragon Great Demon King breathed a sigh of relief, Su Yehan let out a wolf howl and burst into a loud shout, and then, a strong sense of crisis emerged in the heart of the Earth Dragon Great Demon King.

"Not good!"

The Earth Dragon Great Demon King said secretly, and his body turned into a black mang, extremely dodging.

It was so fast that the Spear of Destruction slashed through the air, but the Killing Blade pierced through the neck of the Earth Dragon Demon King.

"You ......" The Earth Dragon Great Demon King was shocked and wanted to say something, but Su Yehan didn't give him this opportunity at all, his heart moved, and with two clanging sounds, the powerful and terrifying Silent Annihilation Void Yuan Slash was sent out again.

At this time, the other three Great Demon Kings had also been killed in front of Su Yehan.

The Thousand-Footed Great Demon King's huge mouth opened, spitting out patches of black mist, enveloping Su Yehan.

The same was true of the Poison Toad Great Demon King, and the Thousand Crane Great Demon King let out a crane roar, releasing a thunderbolt that blasted towards Su Yehan.

"Hmph, that's all, it's far from enough!" Su Yehan said disdainfully.

Then, with a thought in his mind, he held up the shield of death qi, and at the same time, his body quickly retreated, dodging the attack of the three demon kings.

"Buzz!"

At this time, the terrifying buzzing sound came again, and the four Great Demon Kings instantly raised their vigilance, especially the Earth Dragon Great Demon King, because he had already suffered a lot of injuries just after one blow, if it wasn't for its quick reaction, it would inevitably be pierced through the skull by the Killing Blade, so he would definitely die.

"Silence Void Slash!"

Su Yehan's eyes flickered, and two wolf-shaped blades sent out again, slashing towards the Earth Dragon Great Demon King.

Seeing this, the Earth Dragon Great Demon King didn't dare to resist, so he could only quickly dodge, but at this moment, a sense of crisis came to mind, and before he had time to think about it, the Earth Dragon Great Demon King only felt that the surrounding scenery was reversed.

"I ...... What's going on?"

The last question of the Earth Dragon Great Demon King surfaced in his heart, and the next moment, he was completely destroyed and died.

"Ding! Congratulations to the host for killing the eleventh-level Great Demon King, the Earth Dragon Great Demon King, and obtaining 20 billion energy points!"

With the death of the Earth Dragon Great Demon King, the prompt sound of the system sounded in Su Yehan's mind.

"Very good, now that the energy value has reached 470 billion points, if you kill two more Great Demon Kings, you can evolve again!" Su Yehan listened to the prompt sound of the system, thinking so, and looked at the remaining three Great Demon Kings.

He could clearly see the horror in the eyes of the three great demon kings.

Thinking about it, from the time the four of them appeared to block Su Yehan's retreat, to the time when the Earth Dragon Great Demon King was killed, it was only a dozen or so breaths of time, how could this not make them frightened.

The four of them joined forces to besiege and kill a big demon king, and they were even killed by someone, if this is spread out, the three of them don't have to mix.
