As the last stop on the planet against the virus, every aspect of the fortress is staggering.

First of all, there is a very large completely enclosed building, which is not only surrounded by a high wall, but also completely closed to the sky.

The area covered by this fortress is also amazingly large, and with Yang Fan's eyes, he can only see the end of the horizontal line in front of him, where the city wall has not yet finished in the slightest.

I have to say that the power of human beings in the crisis is far beyond everyone's imagination, and who would have guessed that such a huge super building was only completed in a short period of time.

There was a place for planes to be parked outside this fortress, and the aircraft that Yang Fan and the others were riding on was also parked on that tarmac.

"Strange, why aren't there any people in this place?"

As soon as they landed, everyone realized that the situation was wrong.

It is true that it is very dangerous outside now, and there are usually no people staying in this kind of place, but why there is no reaction here after seeing a flying machine, it stands to reason that at least there will be relevant radio and other means of communication to ask, and the people who got off the aircraft did not find other personnel.

"Everyone keep up, ready for battle!"

Everyone walked along the road to the apron to the door leading to the interior.

This gate was made of a special alloy, more than two meters thick, and it was impossible for those infected creatures to open it, but now, this gate had a huge hole in diameter of more than three meters, and it was covered with blood on one side.

It seems almost certain that something has gone wrong, and all the previous preparations have been upgraded to the highest level.

The mecha and steel were covered by their own mechanical armor, and the phantom beasts of the two phantom beast warriors were armored, which was the first time Yang Fan had seen such a magical thing as a living organism turning into armor, and even the five brothers had semi-auxiliary exoskeleton armor outside their combat uniforms.

Walking along the gate, it was completely a slaughterhouse, and the ground was covered with blood, and when a person walked on the ground, his feet would enter the blood.

There were almost no living people here, only a few infected creatures that followed and wreaked havoc here.

"Roar!" A strange creature that didn't know what kind of creature it had mutated from, suddenly rushed towards the team with its bloody mouth open.

"Boom!" Thorns suddenly appeared, slicing the creature into several pieces.

"Let's hurry to the core of the fortress in the middle of here, and hopefully we can find something!"

At this time, everyone had to continue to move forward with blood and water, and as for the mecha and several others who could fly, they were all flying in the air and approaching the target.

The core area of the fortress is where the important government officials of this world work, and why do you say that the government continues to do so much after such a big thing happens, don't joke, public opinion or something will only have an impact on the government, but it will not really shake them.

A bunch of guys who even have to register kitchen knives, do you still expect them to fight the regular army?

Unsurprisingly, everyone who arrived here found that the people here were also missing or dead.

"Captain, I've found something!" The elusive thorn brought some tattered paper this time, "There's a large laboratory underground, this was found underneath, except for this thing, the inside is completely destroyed, can you tell what?" ”

The captain's profession is a doctor, although he doesn't fully understand it, but he really sees a little fame, "This is a research report they did, but the damage on it is too serious, there is no data, are those people here for this thing?" Shouldn't it be, what kind of mystery did this planet get that would attract these guys? ”

Now the captain is also a little uncertain.

First of all, it is certain that a group of people have been here before them, and they are in a completely killing state, completely disregarding the lives of those people.

But the question is, what are the goals of these people?

There can't be anything completely illogical in this world, this planet is an extremely remote planet in the universe, although there are also satellites and other things, but they can't even leave their home planet, they are still too far behind in terms of science and technology, to such a planet to seize their technology? That's a joke.

The only plausible explanation is that the other party is coming for that kind of primitive cell!

But no one knows exactly what happened to the primitive cell.

"Who the hell is it?" A little headache rubbed his head, the captain had to admit that he had no clue now, "Forget it, let's take a look around and look for any clues!" ”

After some searching, an extremely deep pit was discovered in the underground laboratory here.

"What is this hole for?" Everyone was extremely curious about this sudden appearance.

"Let's go down and see!" Wrench said as he took control of a miniature insect robot that dived in.

As the robot went down, he opened the channel that was shared with everyone so that everyone could see what was going on down there.

The hole was not big, but it was very deep, and the robot went deep to find out what was inside.

It was a cylindrical, silver-gray metal rod that was barely known to anyone here.

"What the hell is this? Ugly! The mech muttered after seeing the picture.

"Wrench, please take a look at this little robot control from every direction of it!" Blast seemed a little impressed, but he wasn't sure.

After hearing the request for blasting, the wrench controlled the robot and sent back more detailed information.

Blast looked at the more and more information, but his face was not very good-looking, "It looks like we're in trouble, this is a gravity changer rarely seen in the universe, and it's a pretty dangerous thing!" ”

"Gravity changer? Isn't this thing very common? ”

The device for fine-tuning gravity has long been widely used within the Seven Domains Federation, and I don't know what surprised Blast about this.

"It's different, the principle of the two sides is different! The normal version will only affect the user's body, in fact, it has no effect on the outside world, but this is different, it is a super-destruction weapon that directly acts on the gravity of the planet! ”

"What?" Everyone said that they didn't understand, changing gravity is a weapon of destruction?

"Well, let me explain in detail, this thing is rarely used in the universe, its function is to change the gravitational conditions around it, take this planet as an example, if its gravity suddenly increases a lot, then it will be difficult for it to support the current volume, the entire planet will collapse, what tsunamis, earthquakes, volcanic eruptions and various natural disasters cannot be compared with it at all, then all the creatures here will die, and the planet will be completely destroyed!"

Listening to the explanation, everyone swallowed their saliva and directly destroyed the planet, which is not a common thing in the universe, and it is not a concept to really destroy a planet and destroy the civilized and intelligent beings on the planet.

"It's still salvageable, right?"

"Yes, yes, but I don't think it's possible to have only this one gravity changer, this one is so small and far less powerful, and the other party is likely to place some of the same things in some of the directions calculated around the world!"

"Can you fix this thing, then?"

Blast frowned and smiled bitterly, "I'll do my best!" ”

……

"My lord, the perimeter of the gravity changer we placed at the core of the fortress has been triggered, and it seems that a cosmic mercenary has entered!"

"Those are just small characters, we have to hurry up and evacuate before the regular troops of the Seven Domains Federation arrive, this time the things left by Lord Shadow have been found, we must destroy all traces of this week, as for those guys, didn't you get control of the human defense network of this planet before, just let those things go and play with each other!"

"Yes!"
