The red-winged beast behind him is still chasing, and Wu'an's danger has not been eliminated.

The speed of the red winged beast was so fast that he had no time to run under the ancient city.

"I have another knife!"

At this time, Wu An simply stopped running and wanted to deliver the final blow.

Wu An's divine energy has been exhausted, but he still has a powerful Tianzun body with vast vitality.

That's right, Wu An used his own life force to trigger this last blow!

Wu An held the dragon-slaying knife in his hand, and the strong vitality in his body poured into the dragon-slaying knife like a torrent.

Buzz!

The sword is released, shining in the world!

In an instant, the dim dragon-slaying knife regained its dazzling light!

The Dragon-Slaying Sword trembled, and the sword energy revived, sweeping away in all directions.

Wu An's unlimited physical vitality seems to be more able to activate the dragon-slaying knife than the divine essence, allowing it to show its power again!

There is no limit to the power of this weapon. The more energy you put into it, the greater the power it can exert.

Otherwise, why was this dragon-slaying knife able to slay real dragons and annihilate all living beings in the Dao in the first place?

In just a blink of an eye, the sword energy swept towards the ancient city, like a flying silver dragon, wreaking havoc on the world!

The dragon-slaying knife seemed to have completely revived, and it showed its invincible and domineering power again, seeming to be able to split the heaven and the earth and cut through all things!

Wu An could feel that the power of this sword was even more terrifying than the power of killing that Dao creature!

This lies in the fact that his Tianzun-level body unreservedly injects massive vitality into the dragon-slaying knife.

In order to make this cut, Wu An paid a huge price.

At this critical moment of life and death, he can only do this.

The power displayed by this sword finally alarmed the ancient existence in the ancient city.

"The aura of origin...has the aura of an acquaintance"

"A big killer weapon that doesn't belong here!"

"Who is he? Why can he activate this weapon?"

......

Someone is communicating secretly.

Of course Wu An doesn't know anything that happened in the ancient city. Now he has to face a red-winged beast that is comparable to the Immortal King. The pressure can be imagined.

With this kind of sword power, Wu An can only make one slash.

Therefore, Wu An could only place his hope on this sword.

"If you want to kill me, it depends on your ability!"

A trapped beast is still fighting, let alone someone like Wu An who has a strong will to practice Buddhism.

This red winged beast completely inspired Wu An's fighting spirit. Throughout his practice, he has rarely been forced to a dead end like this.

Just when the red winged beast rushed towards Wu An again, Wu An's eyes flashed with ferocity, he shouted loudly, and fiercely slashed out the dragon-slaying knife in his hand!

The red winged beast is not comparable to the black, cyan and purple winged beasts. It may be jealous or afraid of the dragon-slaying knife, but at this moment its ferocity and pride as the king of the winged beasts do not allow it to back down.

Faced with this terrifying sword, the red winged beast did not dodge, but fought hard with his body!

The void shook and the sword trembled!

In an instant, the two collided again!

But this time, there was no earth-shattering roar.

The sword light is extremely bright, and the sword energy is indestructible!

I saw the dragon-slaying knife cut off a pair of the red winged beast's winged hands with supreme domineering power, slashed directly into its body, and the blade sank deeply into its head!

The dragon-slaying knife burst out with unimaginable power, even if the red-winged beast was a terrifying beast comparable to the Immortal King, it could not stop it.

However, such a terrifying beast did not die there, the ferocity in its eyes still remained.

The red winged beast suddenly waved a broken winged hand and slapped Wu An hard.

Bang!

Wu An held the dragon-slaying knife tightly and was immediately shot away.

A hundred feet away, Wu An stabilized his body and coughed up blood. The knife just now had almost exhausted his life force.

"Even this failed to kill it!"

Wu An looked at the red winged beast in the distance with regret in his eyes.

I saw that the two winged hands of the red winged beast had been severed, and its head was also split in half, revealing the colorful and disgusting brains.

The red winged beast was severely damaged.

But even so, the red winged beast is still fierce and fierce, and it still has fighting power.

At this moment, the red winged beast's scarlet eyes were staring closely at Wu An.

"It's a pity, it's only a little bit short!"

Wu An knew that it was not that the dragon-slaying sword was not powerful, but that he was too weak.

He could only deliver the one blow just now.

Now Wu'an's divine energy and vitality are almost exhausted.

"Maybe we can still struggle!"

Wu An murmured to himself, thinking of the heavenly book in his mind.

Zhizhizhi...

The red winged beast found a scream, and its anger could be heard from the scream.

The next moment, the red winged beast was like a red lightning, shooting towards Wu'an at great speed!

At this moment, Wu An wanted to try to inspire the last resort, and a vicissitudes of voice suddenly sounded from the city wall.

"Don't be so rampant, evil beasts!"

When Wu An heard the sound, he looked up and saw a veteran in armor, carrying a spear, stepping out of the city wall and appearing in front of Wu An in an instant.

Then, in Wu An's eyes, the veteran raised his spear and suddenly thrust forward!

Pfft!

What seemed like an ordinary shot actually penetrated the void and also penetrated the red winged beast.

The power of a single shot is so terrifying!

Wu An looked at the old figure standing in front of him, and his heart was filled with shock.

You know, the red winged beast is a terrifying beast comparable to the Immortal King, but it was penetrated by a single shot by an ordinary-looking veteran.

Unbelievable!

"Could this person be the Immortal King?"

Wu An secretly speculated.

The veteran didn't intend to let go of the red winged beast. After piercing it with one shot, he forcefully picked up the winged beast with a little force of his arm.

Zhizhizhi...

The red-winged beast suddenly struggled violently, but no matter how hard it struggled, it was still unable to break free from the spear.

"You can have extra food tonight!"

The veteran smiled and opened his mouth, revealing a pair of big yellow teeth.

As he spoke, he stretched out his other hand and grabbed the red winged beast's neck.

With a click, the veteran directly broke the neck of the red winged beast like breaking a chicken's neck.

Then, the red winged beast disappeared.

Looking at the scene happening in front of him, Wu An took a deep breath.

This veteran's strength is a little too abnormal. Killing this red-winged beast is as easy as killing a chicken.

Tough and willful, he kills when asked, and this veteran also has the capital to be willful.

"What kind of strength does this person have?"

Wu An couldn't calm down for a long time. Everything that happened on this ancient road far exceeded his knowledge.

The old soldier showed his yellow teeth, suddenly turned around and smiled at Wu An and said,

"Little brother, I'll treat you to a drink tonight!"
