After being improved by Gu Fei, the Zhenbeiguan Formation can not only defend, but also attack.

All I saw was that Gu Fei just stepped on it.

Endless sword light rushed out from the battle at Zhenbeiguan, directly killing all the little sea monsters in Zhenbeiguan into balls of blood mist, and immediately destroyed both physically and mentally.

Even the Black Wind Demon King couldn't stop the sword light that erupted from Zhenbei Pass, and was instantly killed and died.

That’s not all.

Countless sword lights rose into the sky and fell directly towards the sea.

Immortal Lord Tianyue was stunned by this scene.

I saw countless sword lights overwhelming the sky, falling towards the sea like golden rain.

The formation suspended on the sea contains the most elite sea army under the great demon Kunpeng.

Once this overwhelming sword light falls, Kunpeng Great Demon's Hai Clan army will all be killed.

Definitely leave no one behind.

The great demon Kunpeng couldn't sit still.

He appeared above the formation in an instant.

"Whoosh!"

A pair of huge wings spread out from the Kunpeng Demon's back, and the entire sky darkened.

The huge wings directly protected the entire huge formation below.

Countless sword lights fell and were directly knocked away by the pair of wings, and then shattered into the void.

The great demon Kunpeng protected the formation in time.

Naturally, the Hai Clan army on the formation was not affected in any way.

But the sea people outside the formation were unlucky.

When the sword light fell, the three sea dragons were instantly pierced by the sword light and turned into a hornet's nest.

That's the North Sea dragon.

The North Sea Dragon is no small character.

If a human monk goes out to sea to hunt monsters and encounters this North Sea dragon, there will only be one end, and that is to become the food of the North Sea dragon.

In the eyes of the demon clan in Beihai, the human race is nothing more than food.

Among all races in the world, the strong are respected.

There is nothing to say about this.

"boom!"

At this time, a terrifying demon power erupted from the sea, and the entire void of heaven and earth was shaking.

The situation on the sea suddenly changed color.

The whole sea was rough and the waves were huge.

Huge waterspouts appeared on the sea like giant dragons.

Then, the water began to recede rapidly, exposing the seabed.

"not good!"

On the top of the city, Immortal Lord Tianyue couldn't help but be shocked when he saw this scene.

"The tsunami is coming."

Immortal Lord Tianyue exclaimed.

"Tsunami?"

Gu Fei put down the teacup in his hand and looked towards the sea.

All I could see was the sea, with the water receding quickly.

Kunpeng, the great demon, is exerting great supernatural powers, and his power is unparalleled.

Behind him, endless sea water was gathering, and a huge wall of water rose from the sea behind him.

Hundreds of feet, thousands of feet, ten thousand feet.

In Zhenbei City, countless human monks were shocked when they saw this scene.

The Kunpeng Great Demon actually wants to cause such a powerful tsunami?

Can Zhenbeiguan's defensive formations be able to block such an attack?

Gu Fei was looking forward to it.

Who is this Kunpeng Great Demon trying to test?

The corners of Kunpeng Demon's mouth raised, revealing a sneer.

"go!"

The great demon Kunpeng's wings trembled.

The next moment, the wall of water behind him surged forward.

"Rumble..."

An extremely shocking voice sounded.

The whole world was shaking.

The tsunami thousands of feet high surged forward unstoppably.

Gu Fei looked up.

I saw a white line on the horizon moving quickly towards Zhenbeiguan.

Even though they are still far away, countless human monks in Zhenbei Pass can already feel the vibrations coming from their feet.

A shocking sound came from the direction of the sea.

Like thousands of horses galloping, and like muffled thunder roaring.

The sound became louder and louder, and the vibrations from the ground became more and more violent.

Everyone was frightened and looked for a place to hide.

The tsunami of terror has arrived.

Wherever the tsunami passed, it shattered everything and destroyed everything.

All the human monks in Zhenbei Pass were extremely frightened.

At this time, within the defensive formation at Zhenbeiguan, the formation masters in the formation's eyes realized that they could control the formation again.

They did not hesitate and immediately activated the formation's strongest defensive formation.

"Buzz!"

The void shook, and Zhenbeiguan's defensive light barrier instantly increased tenfold.

Not only the entire Zhenbeiguan, but also the area with a radius of hundreds of miles around Zhenbeiguan was shrouded in Zhenbeiguan's defensive light shield.

The furious sky-swallowing fire sparrows in the sky also retreated away.

That guy Kunpeng finally took action.

The Sky Swallowing Fire Bird was very unhappy.

Several of its claws were broken, and it was really abominable that this guy Kunpeng took action.

This guy definitely wants to see the joke.

At this time, the sky became dark.

The violent waves slammed down on the defensive light barrier below.

The whole world is trembling.

This is the power of heaven and earth.

The super tsunami caused by the Kunpeng Demon is truly earth-shattering.

If it were the previous Zhenbeiguan formation, it would be really difficult to withstand this terrifying tsunami.

Moreover, the tsunami can also cross Zhenbeiguan and sweep directly towards Zhenbeicheng behind Zhenbeiguan.

Zhenbeiguan and Zhenbeicheng are protected by formations, but the area between Zhenbeiguan and Zhenbeicheng is not protected by formations.

You can already imagine the fate of countless people without the protection of formations.

"Why!"

Gu Fei sighed, can't you just let me drink tea quietly?

"Rumble..."
To be continued...
