Rocky and Orton have been in contact with each other, and the reason why he dared to let the guards retreat underground, and also let Karina completely blow up the institute, was that he had received Orton's notice that the mobile fortress had been fully charged!

He'd seen the Mobile Fortress with his own eyes, and as long as that big guy was fully charged and successfully activated, then he would definitely be able to come out with a few hundred of his guards.

So when Lilia asked him, Rocky nodded directly, and then looked high in the air to the ground, obviously waiting for when and where the mobile fortress would come out.

Not only him, but Lilia and the others around him were also looking at the ground, carefully looking at the ruins, and at the same time Karina, who commanded the fleet, was the same, and even when Rocky and the others took off, Karina flew directly out of the flagship and flew into the air, even the sailors on the battleship were lying on the side of the ship at this time, looking down at the ground.

Everyone is looking forward to the appearance of the mobile fortress at this moment.

A minute passed.

Ten minutes passed.

Thirty minutes have passed......!

In the blink of an eye, half an hour passed like this, but in the process, people never found any movement in the ruins, in the sight of Rocky and others, the earth was still full of demons, and the black pressure of the demons had covered the entire ruins, and as far as the eye could see, they could only see the demons who trampled the ruins under their feet, and they couldn't see the ruins at all.

As a result, everyone began to worry, including Rocky.

Orton had previously said that the fortress had been charged and could be activated, why did it take so long and still be missing, what the hell is going on?

What made Rocky even more unsettling was that he had contacted Orton several times during this period, but he never received a response, and he didn't know if Orton's stubbornness was another reason for not wanting to deal with him, or if there was really some accident......

A hint of unease, a hint of foreboding, at this time surrounded people's hearts.

But at this moment, just when everyone's hearts were beating a little drum, a loud bang suddenly came from the ruins!

Bang......

Bang...... Bang......!!

The sudden sound was like a landslide cracking the ground, causing the entire ruins to shake in this loud rumbling sound, and this sound naturally attracted the attention of Rocky and the others, but when they wanted to follow the sound, they found that the sound was too loud, so loud that it was impossible to judge the source, and they only felt that the whole earth was trembling.

Fortunately, Rocky and they may not be able to determine the specific location of the sound, but the demons on the ground, especially the large number of black-eyed demons with extremely sensitive hearing, instantly determined the direction and pounced in the same direction.

In an instant, the Black Suppression Demon gathered near the research institute suddenly surged in one direction like locusts, and this scene made Rocky and the fleet in the air immediately follow, flying in the direction of the demon's movement.

After a short time of following the demon, everyone stopped, for they had found the source of the loud noise.

In everyone's eyes, a crack was gradually opening in a huge clearing in the ruins, as if a door was being opened, and the loud noise just now came from the crack opening.

And as the gap gradually opened, the surging demons arrived, and then countless demons rushed into the gap!

This scene made Rocky and the others frightened, because this gap was obviously artificially opened, so it was a channel for the mobile fortress to move, but now it was flooded by demons, would this threaten Orton and the others?

Rocky's worries are reasonable, but they are obviously overthinking!

Because just as the crack was completely opened, a tall fortress was opened out of the ground!

Mobile Fortress ...... Finally appeared!

Seeing the mobile fortress rush from the ground to the ground, Rocky herself, and everyone around her, couldn't help but wave her arms high, and finally drove out! Orton finally activated this behemoth!

But the moment he raised his arms, Rocky's heart sank, because although the mobile fortress successfully opened out of the ground, don't forget how many demons there are in the ruins! In fact, it is true, because when the mobile fortress opens to the ground, this big guy is instantly surrounded by endless demons in the center!

What can I do?

Finding that the fortress was surrounded by demons as soon as it appeared, Rocky frowned, and then just as he was about to give the order, he heard a series of cannon shots!

At this moment, the sound of shelling suddenly appeared, and everyone who heard this sound hurriedly looked towards the source of the sound, and then saw that the muzzles of the guns on the mobile fortress were erupting with fire at this moment!

The rumbling cannon was heard again, but not from the fleet, but from the mobile fortress!

As I said before, the mobile fortress is dozens of meters high, and it is a veritable behemoth, and on this behemoth is a horizontal and vertical installation of countless cannon barrels, these bystanders are long, thick and thin, making the fortress like a hedgehog full of spikes.

Now, these spiky barrels are firing in unison, and the artillery fire covers an extremely wide area, with the fortress as the center, starting from the nearest four weeks and spreading to a few hundred meters away, all of which are enveloped in artillery fire!

Under such a large range and 360 degrees of bombardment, the surrounding groups of demons were instantly reduced in large numbers, and it can be said that hundreds of them were killed in an instant!

"Good Fellow......"

Seeing that hundreds of demons were killed under the repeated bombardment of the fortress, Rocky gasped, because this scene was shocking even for him, he had never seen any weapon other than the fleet that could cause such great damage, no, it should be said that the lethality caused by the mobile fortress was even greater than that of the fleet, because the fleet was not composed of one warship, but a group of warships, but there was only one mobile fortress in front of him!

And what makes Rocky even more happy is still to come, that is, after the bombing, the mobile fortress is really in action!

As mentioned earlier, when the number of demons exceeds a certain limit, the effect of the bombardment is very small, so when the bombardment of the mobile fortress is over, there are also many demons alive around, and all of these demons rush towards the fortress.

However, the moment these demons rushed to the fortress, the fortress was directly activated!

The loud rumbling sound reappeared, and the huge fortress looked like a moving hill after it was activated, and all the demons who dared to block it along the way were crushed to pieces by its huge body, and a bloody path was pressed out of the ruins!
