The deafening roar has been the theme of the mountains for a while, and the huge steel machinery slowly but surely pushes forward, crushing everything in its path.

The beasts, large and small, had long been frightened and fled, and some of them charged at the ark in a rage, but they were killed by rapid-fire cannons before they could get close.

The fighters have turned on the anti-noise mode, which is not affected by the noise in the slightest. It's nothing if you can't hear the outside world, and such a loud wave can disable the ears of any living being.

Just when the fighters thought that the day would be spent in the same hectic as before, a short, piercing alarm suddenly sounded in the communication channel. This is the highest level of alert, which means that an enemy attack is imminent. And what other enemy attacks on planet 4 are nothing more than beast tides.

The emergency plan that had been prepared for a long time was immediately activated, and the six Arks abandoned the harvesters and roadheaders at the same time. These are all dozens of tons of big guys, and after throwing them away, the ark's movements are much lighter.

They turned on their full power, accelerated at full speed, and retreated in the direction of the base. While evacuating, all the raw materials that have not had time to be processed in the cabin are dumped out to reduce weight. Anyway, these raw materials are dirt trees, and they are everywhere, so there is nothing to be sorry for.

The heavy-duty trucks were relatively nimble, and had already retreated ahead of time before the massive ark had completed its U-turn, fleeing at full speed towards the base. From the base to the mountainous area is a relatively flat road, the speed of the truck is also greatly improved, even if it pulls hundreds of tons of materials, it can drive nearly 100 kilometers, if the road is not flat, the speed can be increased again.

As soon as the ark began to accelerate, the first wave of the beast tide arrived. Thousands of aerial war beasts roared, covering the sky above the Ark group in the blink of an eye!

And then they were tragic.

The Arks were lined up in dense formations, each with more than 30 twin rapid-fire guns, and when the six Arks were gathered together, they formed a cannon group of more than 200 rapid-fire guns, with extremely ferocious firepower and no dead spots at all.

Hundreds of blazing flames swept through the air, sweeping down large swaths of the aerial war beasts. These beasts are still in the habit of chirping loudly, hovering in the air, and then looking for an opportunity to swoop down and swoop down on their prey. However, the firepower of the ark was so fierce that the battle beasts circled in the air with more than half of their effort.

The few remaining eagles broke through the fire net and swooped down on the ark, only to find that armor was piled up everywhere. Their teeth and claws are so powerful that they tear off large chunks of armor with a single bite, but the thickness of the ark's armor is measured in meters, and this damage is a scratch at best.

There were still many hidden bunkers on the surface of the ark, and the soldiers stationed there suddenly opened fire with large-caliber weapons, killing the unprepared war beasts one by one.

In the blink of an eye, the first wave of flying units had been wiped out. Not only did the melee attack be like this, but even a small group of high-altitude bombing beasts did not escape the doom and were easily cleaned up by rapid-fire cannons.

No matter how strong the body of the war beast is, it is difficult to resist the powerful rapid-fire cannon shells. These shells couldn't penetrate them, and could only blow up big holes in them, but this damage was enough, and they fell headlong into the ground one after another.

The Ark group did not stop at all, and accelerated away. At this moment, the earth can already feel a clear tremor, and smoke and dust are rising in the distance, and I don't know how many war beasts are swarming here!

The overwhelming herd of alien beasts rushed up at an astonishing high speed, and they even ran at a speed of nearly 200 kilometers in an instant. Compared to previous beasts, they are significantly thicker, faster, and more powerful in attack.

The alien beast herd caught up with the ark in the blink of an eye. The rapid-fire cannon fired wildly, sending the alien beasts flying in all directions, but it still couldn't completely block the approach of the alien beasts.

In the blink of an eye, a large number of alien beasts climbed onto the ark and began to tear wildly. Their attack power was much higher than that of the flying beasts, and in the blink of an eye, several surface bunkers were torn apart, and the warriors inside were dragged out alive and torn apart in an instant.

However, despite being covered with war beasts, the ark still drove at high speed without stopping.

Hundreds of chariots suddenly appeared in front of them, and the chariots had already received orders to fire at the ark from a distance. They fired high-explosive shells, ejecting countless metal projectiles, giving an indiscriminate baptism to the surface of the ark.

The power of the chariot cannon was more than bearable for the Ark, but the alien beast was not so good. A large number of projectiles shattered their skin and flesh, blood burst out, and they fell from the ark with a cry of pain.

The chariot herd mixed with the ark herd and retreated together. The ark intercepts the hordes of alien beasts with a barrage, while the chariot is responsible for picking up the alien beasts that rush through the barrage.

However, there are so many beasts that the drivers of each chariot are veterans of many battles, and they dare not be distracted in the slightest. They can even shoot desperately on instinct.

The fierce battle lasted for nearly half an hour, and the battle lasted for a full 40 kilometers, and the alien beasts were finally left behind.

Fighting fiercely all the way, the alien beast herd paid the price of tens of thousands of heads, and in the end only destroyed more than a dozen chariots.

With the Ark and the tank herd in place, the fragile convoy of trucks was able to safely withdraw to the base.

Then the Ark group and the chariot group also retreated, and the ark immediately entered the designated position, urgently replenishing ammunition while defending on the spot, while the chariot group entered the base and regrouped in the rear.

A moment later, the entire Base 2 was filled with a heavy killing force, like a dormant hunter, quietly waiting for the arrival of the beast tide.

It was only a few hours before a black tide line appeared on the distant horizon. The beast tide did not rush over in one go, but slowly approached. The tide line alone on the earth is thousands of meters wide, and I don't know how many war beasts are hidden in the billowing smoke and dust. The only thing I know is that the scale of this beast tide is larger than the last time, and its combat power is also more terrifying.

Chu Jungui stood on the top floor of the command building, overlooking the beast tide in the distance. Numbers kept beating in his field of vision, locking on a war beast that had never been seen before, or that had clearly mutated.

The numbers jumped wildly, and with a glance, the war beasts that Chu Jungui saw were already close to 100,000, and the follow-ups were still appearing!

This is an unprecedented beast tide, enough to bulldoze several bases like the Shadow of Doom in the Federation, and the original No. 2 base will be bulldozed seventeen or eighteen times. Its number alone is far greater than before, and there are several brand-new war beasts in it, among which there are several mountain-like figures in the center of the beast tide, and every step will cause the earth to tremble, even Chu Jungui standing in the command building can feel it.

Li Ruobai, who was next to him, looked a little reluctant at the moment, and said: "These guys don't seem to have made much progress, and they don't pay attention to the air force, if there are more missiles ......."

Before he could finish speaking, he saw a dark cloud appear in the distant sky, and it was coming rapidly!

If you get closer, you can see clearly, it's not a dark cloud, but countless living missiles!
