"Buzz ......"

Suddenly, a strange humming sound suddenly came from the wilderness outside the southern city gate. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

The sound was weak at first, but as time went on, the humming became more and louder.

In the end, it was not only some sharp-eyed samurai masters who could hear it, but even some ordinary soldiers, they could faintly feel that there seemed to be some unusual faint voices coming from the air outside the city.

Shen Hongyu's martial arts strength is the highest, so she is the one who senses the humming sound one by one.

When she heard these buzzing noises coming from outside the city, her pretty face changed on the spot, and she hurriedly pulled Nie Zheng who was standing beside her, and quietly reminded: "Did you hear anything?" ”

Nie Zheng turned his head to look at her, and found that Shen Hongyu's bright eyes were solemn, and on the spot, his heart moved, and he hurriedly closed his eyes and listened attentively.

Sure enough, within a few seconds, Nie Zheng faintly heard a faint hum like a dark tide, accompanied by a breeze that slowly passed into his ears.

"What a strange sound, could it be some poisonous insect?"

Nie Zheng and Shen Hongyu beside him glanced at each other, and both of them saw a trace of deep worry in each other's eyes.

At this moment, the five Tiger tanks had already chased out of the city more than two miles away, except for sending someone to call them back, Nie Zheng was standing at the head of the city, no matter how loud the voice was, it was estimated that he would not be able to let those clone soldiers who controlled the tank hear.

After all, when these clone soldiers are driving the tank, the crew will make some loud noises, which will affect the hearing of those clone soldiers.

However, since the enemy's 1,000 Iron Ox heavy cavalry was completely annihilated, the five Tiger tanks did not need Nie Zheng's summons, they directly turned their heads and quickly drove towards the city defense.

After seeing this, Nie Zheng secretly breathed a sigh of relief.

As long as the five Tiger tanks could be successfully withdrawn to within 100 meters, he could immediately send them and twenty-five clone soldiers back to the arms mall.

Anyway, the ammunition in the tank had already been exhausted, and leaving it outside the city somewhat obstructed the view of the heavy machine guns.

Outside the southern city defense, the strange humming sound became louder and denser.

This made the people stationed in the city defense secretly puzzled.

Except for a few leaders, the Dragon and Tiger Rebels who were basically stationed above and below the city defense, they didn't feel that the buzzing sound that suddenly sounded outside the city would pose any threat to their side, but they just felt a little strange in their hearts.

Although the ordinary soldiers didn't have any special reactions, Nie Zheng and the other core leaders had already begun to feel that something was wrong.

It is a well-established fact that the Dayue people are insidious and cunning, and they are good at evil tricks.

At this moment, above the Nancheng Tower, all the leaders and masters were secretly vigilant and firmly protected Nie Dashuai in the middle.

Especially Shen Hongyu, when the strange humming sound sounded, a layer of pale golden body protection true qi burst out from her body, blocking in front of Nie Zheng.

Until the reality of the buzzing sound is clarified, no one is allowed to be careless.

At this time, Nie Zheng suddenly instructed Shi Zheng and other generals: "Pass the order, everyone should be vigilant, keep their eyes sharp, and as long as they find any abnormal movement in the wilderness, immediately open fire and bomb!" ”

Hearing this, Shi Zheng nodded deeply, bowed and said, "Obey, handsome!" ”

After that, he led a group of generals and leaders to prepare for battle.

After they left, Nie Zheng picked up the military telescope again and carefully observed and searched in the wilderness.

He wondered where the strange buzzing noises that suddenly sounded outside the city came from.

With the telescope in his hand, he continued to move and search the smoke-filled wilderness, and finally, he discovered an extremely unusual anomaly.

I saw that on the wilderness within a radius of more than ten miles outside the city, the bloody and broken cavalry corpses and the giant bison corpses were scattered all over the wilderness.

Among them, some of the corpses closest to Nanchengfang are estimated to be less than 1,200 meters.

However, on top of the carcasses of those bloody, severed bison, there was a faint layer of dark yellow dust.

Because the distance was too far, and now the sky was gradually getting darker, so Nie Zheng couldn't tell what the "dark yellow dust" surrounding the bison carcass was.

However, what Nie Zheng was sure of was that the strange buzzing noises coming from the air seemed to come from those bison carcasses outside the city.

"Young Eagle, did you find anything?" Shen Hongyu suddenly asked.

Nie Zheng turned his head to look at her, nodded, and said, "I found some strange things on the carcasses of those bison outside the city, a bit like dark yellow dust, but I can't see what it is, your eyesight is better, or you can help me observe." ”

After that, he handed the telescope in his hand to Shen Hongyu's hand.

Shen Hongyu picked up the binoculars and quickly looked at the carcasses of the bison.

Suddenly, her pretty face sank, and she exclaimed in a low voice: "Ants, no, there are a lot of them with wings......"

As soon as these words came out, Nie Zheng's face changed, and he hurriedly took back the telescope from her hand and looked out of the city again.

However, at this moment, the five Tiger tanks let out a dull roar in the wilderness and quickly drove towards the city gate.

Nie Zheng looked at the distance, the five Tiger tanks were already less than a mile away from the city gate, and with their speed, they could withdraw in a few minutes at most.

However, just when the five Tiger tanks were less than 400 meters away from the city defense, a change suddenly appeared!

Through the telescope in his hand, Nie Zheng clearly saw that all the bison corpses scattered on the wilderness, at this moment, the dark yellow dust that shrouded their bloody bodies suddenly exploded in the wind like a yellow powder mist.

Immediately afterwards, on the entire wilderness, dark yellow dust flew all over the sky, instantly forming a yellow sandstorm several kilometers long, overwhelmingly sweeping the sky.

The speed of this yellow sandstorm was extremely fast, they flew up and down in mid-air, seemed to have the right direction, and swept towards the southern city defense with great speed.

It's so fast that it's hard to describe in words.

In just a few seconds, the yellow sandstorm caught up with the five Tiger tanks that were moving.

Immediately afterwards, a scene that shocked Nie Zheng and the others appeared!

I saw the yellow sandstorm that was several kilometers long, and they swept down from mid-air, and in the blink of an eye, five Tiger tanks were enveloped in it.

In an instant, five heavy tanks weighing dozens of tons, under the gaze of Nie Zheng and others, were constantly corroding, piercing, and melting at a speed visible to the naked eye......

In the end, all that was left was a pile of rubber wire skins, and some miscellaneous non-metallic items.

The five clone soldiers who had been sitting in the tank were standing on the empty ground with pale faces at the moment, looking at the yellow monsters that were constantly flying around them, and their expressions were extremely frightened.

At this moment, not only those clone soldiers were full of horror, but all the generals and soldiers stationed in the southern city defense were all stunned and speechless in shock.

Especially Nie Zheng, his face was extremely gloomy.

It wasn't until that moment that he could see clearly what the kilometer-long "yellow sandstorm" was.

It turned out to be a swarm of flying ants, yellow flying ants with wings.

The number of flying ants is so large that it is impossible to estimate the number of them.

Through the telescope in his hand, Nie Zheng had just seen clearly, the five Tiger tanks were besieged by countless yellow flying ants, and they were corroded and melted clean in an instant.

Obviously, these yellow flying ants can excrete a very corrosive formic acid, which has a very terrifying corrosive ability against metals.

After being surrounded by these flying ants, it took less than a minute for the five Tiger tanks and the big guys weighing fifty or sixty tons to be completely corroded.

The corrosive ability of this group of strange flying ants is simply terrifying.

What made Nie Zheng's scalp tingle even more was that these terrifying flying ants, they were extremely aggressive towards metal, or they were unusually interested in metal, and their flight speed was also terrifying.

A distance of hundreds of meters, it came in a few seconds.

However, Nie Zheng also discovered a very crucial detail, these flying ants seemed to be only interested in metal, and they ignored anything other than metal, including humans, and had no intention of attacking at all.

Because these flying ants don't attack anything other than metal, the clone troopers hiding in the control pod were able to escape unharmed. This is also a blessing in misfortune.

Faced with the attack of such a large number of terrifying flying ants, Nie Zheng had no choice but to order a counterattack.

Although he knew very well in his heart that the heavy machine guns and mortars he possessed could not pose an effective threat to these overwhelming flying ant colonies, he could kill as many as he could. Otherwise, once those flying ants rush into the city defense, basically, all the arms and weapons deployed in the southern city defense will be scrapped.

"Everybody, fire!"

Under Nie Zheng's roar, all the heavy machine guns, mortars, and bazookas ...... All of them launched the largest counterattack in history against the "yellow sandstorm" outside the city.

However, in the face of such a group of terrifying ant colonies that moved quickly and could fly in the air, Nie Zheng and the others were helpless at all, and they had no way to deal with it.

All the bombing and strafing were in vain.

In addition to being able to kill a very small number of flying ants, the remaining flying ants still turned into a terrible "yellow sandstorm" in mid-air, overwhelmingly sweeping the entire southern city defense......
