"Howl ......"

"Roaring ......"

Suddenly, two terrible long howls came from the west of Ningcheng.

As this long howl sounded, a tremor of extreme intensity followed.

For a while, the entire land of Ningcheng seemed to tremble several times.

Incredible things happen!

The army of zombies and beasts besieging Ningcheng seemed to have immediately become extremely manic, and they all launched an even more frantic assault on the four gates of Ningcheng without fear of death.

"Boom ......"

At the same time as the army of zombies and alien beasts frantically attacked Ning City, a black pillar of smoke suddenly rose up in the western sky after a muffled sound like thunder.

For the sudden change in the Western Skyrim without warning, almost all the Evolutionary warriors couldn't help but feel unprepared!

The mysterious black pillar of smoke, almost like a precursor to a volcanic eruption, suddenly burst out, and from a distance, the black pillar of smoke was extremely thick, soaring straight into the sky with the momentum of thunder.

It carries with it an incomparably terrifying aura of death!

Even, Ningcheng, which was 30 kilometers southeast of the smoke column, could clearly see the smoke column.

First, a violent earthquake struck, causing the whole earth to tremble.

Then, a roaring shock wave spread out in all directions like a tsunami.

For a while, the wind was howling, and the sand was flying!

The mountains and forests swayed wildly, and some ordinary people couldn't even stand on their feet under this strong wind, and countless hats and clothes were blown into the sky.

What's even more bizarre is that this storm also carries a gloomy and calm momentum......

"What's going on?"

"A typhoon is coming?"

"Earthquake? No. It's not an earthquake ......"

"Not good. The army of zombies and beasts besieging our base seems to have gone berserk. Their attacks were even more violent......"

......

For a while, the faces of countless evolutionary masters changed one by one, and their eyes couldn't help but widen. Breathing in the bloody and foul-smelling air, looking at the western sky, it seems that I also faintly feel a faint sense of suffocation and strong pressure hitting my heart.

Under the west gate of Ningcheng, Xu Xinyan woke up from her mind and looked at the west with a solemn face.

Obviously, just now. A terrifying and strange change has occurred in the west of Ningcheng!

Similarly, the four phoenix guards who were guarding Xu Xinyan were also shocked. Since they followed Xu Xinyan, their strength has improved extremely quickly, and almost all of them are evolutionaries at the peak of the third order. The strongest Fengwei Deng Nanxiang is a fourth-order primary evolutionary.

"What the hell is going on?"

Fu Yunxian, one of Xu Xinyan's four phoenix guards, spoke out a little nervously, and she couldn't stay calm, because the sense of coercion coming from the air was too powerful, and the place where the black smoke column rose was at least 30 kilometers away from Ning Zhen.

Such a long distance can also make the entire Ning City Evolver feel pressure, and the power of this mysterious thing makes her feel terrified!

Just unleashed a [Fission Fireball]. Another Fengwei Zhang Qiurong said a little breathlessly:

"Also...... What else, then...... There was an extremely powerful dark power in the black smoke column. Obviously, in the west of Ningcheng, there is a dark creature that may be stronger than the Lord. Worse...... This mysterious dark creature seems to be heading this way......"

The rest of Yun Ke and Deng Nanxiang were so tired that they almost collapsed. But at this time, he was also in a hurry.

A beautiful face with a touch of unquenched fear.

Deng Nanxiang is a fourth-order evolutionary of the dark system, and he is good at dark summoning. At this time, she forcibly dragged her tired body, walked in front of Xu Xinyan, and said anxiously: "Xinyan, it's not good, there seems to be a change in the West." I already felt a terrifying breath of death...... Have a strength of at least the sixth order...... The powerful corpse clan emperor rushed over, and there may be three fifth-order mutant beasts, or even more!Xinyan, what should we do?"

"South...... Nanxiang, Fu ...... Help me!" Xu Xinyan was even more tired, since becoming the leader of the Ningcheng base, she has been forced to bear an unparalleled burden and pressure. She has been able to hold on to it until now, and she is already very strong. You must know that if it weren't for the apocalypse, she would be an eighteen-year-old college freshman.

Seeing that Xu Xinyan, who had always been strong, actually wanted to help her by herself, Deng Nanxiang realized how tired Xu Xinyan was. Hurriedly stretched out his hand to support Xu Xinyan's waist, "Xinyan, your strength and physical strength are too overdrawn, why don't you go back to the city to rest first, and leave the battle to us later......"

"Over to you?"

Xu Xinyan forced a shallow smile and shook her head, "You are also very tired! Let's all retreat into the city. As for the zombie emperor who came from the west, it's not something I can deal with now. Let's wait and talk about it, if Brother Chong can appear, any zombies will have no return......"

Speaking of this, Xu Xinyan's heart couldn't help but feel gloomy. She hadn't seen Lu Zhong for almost a month.

If you know that Lu Dao Lu Chong's strength is strong, however, this is the real Doomsday Realm, and this Realm is full of endless dangers. She was also faintly worried about Lu Chong.

Deng Nanxiang has heard the "Brother Lu Chong" mentioned by Xu Xinyan more than once, but she has not seen it.

She is also very curious about the most mysterious first leader of this base, plus she is not competent at all.

If Lu Chong is really so powerful, then why haven't you heard of his achievements? In Deng Nanxiang's view, Lu Chong is just the sustenance of Xu Xinyan's girlish feelings. Because of his admiration, he deliberately showed Lu Chong's strength. As for Yu Tiejun, it was only because of Lu Chong's gratitude for saving his life that he recognized Lu Chong as the number one leader of the entire Ningcheng base.

Deng Nanxiang did not say anything to refute, but said calmly: "Okay then, let's retreat into the city first!"

Xu Xinyan nodded, and then expanded her spiritual power with all her strength, and transmitted to the evolutionary who was fighting: "At this time, the zombies and alien beasts are in full swing, everyone retreats into the city, and it is okay to defend the city with all their might, it is not appropriate to fight to the death outside the city......"

Xu Xinyan didn't notice at all at this moment that a fifth-order zombie could actually disguise, and she was also disguised as an ordinary zombie and gradually approached her.

Dangerous. Quietly approaching. But Xu Xinyan didn't know it

......

"General Yu. Now what are we going to do!"

The evolutionary warriors of the North Gate also changed their faces one by one. They all shouted loudly.

The army of zombies and alien beasts in front of them made them tired and suffered heavy casualties, if the dark creatures stronger in the West attacked me, how could they withstand it?

It's not that they don't have a bloody battle, but the situation in front of them is extremely unfavorable, and fighting to the death will only make the losses heavier.

Like those alien beasts and zombies of different sizes, they are constantly screaming, causing earth-shattering noises and roaring. The whole space shook and scared a lot of female evolutionaries enough.

Moreover, the overwhelming tide of zombies, with a monstrous corpse smell, is extremely pungent.

And the carrion of zombies can be seen everywhere in both eyes......

Stimuli such as sounds, smells, and sensations can greatly reduce the morale of human evolutionaries and at the same time, their momentum. Now, sensing that an even more terrifying danger was approaching in the distance, and hearing Xu Xinyan's voice again, all the evolutionaries had a feeling of scalp tingling.

These days, the evolutionary team led by Yu Tiejun has killed many zombies. The mind has been tempered like steel.

But now, they were suddenly facing a huge number of corpses. They also had to face a zombie emperor with a stronger process, Xu Xinyan and Yu Tiejun, which made them terrified.

After all, everyone knows how powerful zombies are!

The corpse clan originally had an immortal physique, which was extremely difficult to kill. When facing zombies, factors such as corpse poison, stench, and suffocation will reduce people's combat effectiveness, so a corpse clan of the same level must have two human masters to deal with!

And the arrival of the Zombie Emperor, I am afraid that the attack power and destructive power of the entire zombie army will increase by geometric levels.

"What should I do? of course withdraw! Hurry up and withdraw to the city for Lao Tzu—"

Yu Tiejun yelled anxiously, and directly gave the order to retreat without thinking about it.

After all, the terrain outside the city is flat, and there is no way to use the geographical advantages to fight against the corpse clan and the beast clan alliance, only by returning to the place where the houses in the city are densely populated, it is possible to use the buildings to carry out street battles and guerrilla warfare with the zombie and beast alliances!

As for whether the innocent civilians gathered in the city will be killed by zombies and strange beasts...... Yu Tiejun won't care.

He passively became the third leader of Ningcheng. In his heart, except for Xu Xinyan and Lu Chong and his own son, he will not take anyone's life or death to heart.

If he hadn't followed Xu Xinyan's side, he might have seen Lu Chong again, and he would have left a long time ago.

Yu Tiejun, who has "died" once, obviously cherishes his life even more.

However, he didn't want Xu Xinyan to be left alone to support the operation of the entire base, so he would be too sorry for the life-saving benefactor Lu Chong.

In desperation, he has been staying by Xu Xinyan's side......

"Retreat...... Retreat? No, the walls of our northern city have not been built yet, do we want to let zombies and strange beasts rush into the city after us, our relatives can live in it......" Zhang Lei, a fourth-order evolutionary of the Ningcheng military, couldn't help but cry out unconvinced when he heard Yu Tie's retreat order.

"You idiot, right?" Yu Tiejun glanced at Zhang Lei fiercely and said, "Forget it, I'm too lazy to talk nonsense with you." If you don't retreat, you can just help resist the army of zombies and alien beasts. Lao Tzu takes the first step......"

After speaking, Yu Tiejun waved his hand violently, and led his subordinates to take the lead in rushing back to the city.

Zhang Lei was stunned for a moment, and a gloomy killing intent flashed in his eyes.

In the current situation, he naturally understood that retreat was the most correct choice. However, once retreated, there will naturally be serious consequences.

And this evil consequence is not something that their military wants to bear.

What's more, the sudden rise of Xu Xinyan and Yu Tiejun made the military very dissatisfied. After all, as soon as these two people rise, their prestige is too great.

"Damn it, you ordered you to retreat. Wait for this tide of corpses and beasts to pass, and see if Lao Tzu will send you to a military court......"

Zhang Lei gave an order to his army and decisively retreated back to the city. (To be continued......)
