The thirteen districts of the United States.

The mayor and Jay stepped into an elevator that went straight underground, with only "-1" to "-12" buttons, and placed his left hand on the palm-shaped palm print verification machine, and pointed his left eye at the iris reader.

"Drop! Verified! ”

Then suddenly a "-13" floor display appeared below the "-12", and the elevator began to run downward.

Hearing that there was something wrong with "Thirteen", the district chief was in a very bad mood at the moment, which meant that Jay's analysis was probably correct.

In addition, he didn't expect that the aliens still had the ability to control the "Thirteen"! Precautions have been taken, why is this happening?!

But what will the aliens' revenge be? Could it be some kind of devastating attack? The mayor's heart was full of worry.

Jay looked at District Chief Tie Qing's face, and wanted to ease the tense atmosphere. "Hey K, don't worry too much, Thirteen's weapons are limited, so even if they blow themselves up or something, at most they will blow up Thirteen, and the earth should still be safe......"

Mayor: "......"

It's even worse......

……

Soon, the two arrived at the "-13th floor", and as soon as they got out of the elevator, a researcher in a white coat hurriedly greeted them, "District Chief, this way!" ”

As he spoke, he led the two of them to the observation window of a large experimental site.

In the center of this huge experimental site, a black sphere is supported by a steel bracket, and in the center of this sphere, the red and blue letter "B" is also engraved.

The sphere seems to be originally connected with dense various pipelines, and the other end of the pipeline is connected to a transmission tower like a signal receiving pot lid, but at this moment, these pipelines seem to be torn off, leaving only a small section on the spherical object, and some pipelines are still "zizi~" sparks.

This sphere is the most mysterious alien weapon in the Thirteenth District, "Thirteen"!

"What the hell is going on?!" The district chief looked at the messy experimental field.

"Not long ago, the core component of 'Thirteen' suddenly activated on its own, forming something like a stance shield on the outside, ripping off all the outer pipe wires, and now it seems to have entered a state of self-excitation, it is ...... Collect gravitons! ”

"How is this possible! In order to prevent this from happening, we should have put in place safety isolation measures, and its energy components should have been pre-separated, right? Why is this still happening?

The energy lines are all torn off, there is no external power supply, what does it drive on? The district chief frowned.

"Alas...... That's true, but we never expected it to have some kind of backup energy system in its core components......" the researcher reluctantly.

"What?! Why didn't I know anything about it before! The district chief was a little angry.

"This ...... As you know, our understanding of the graviton is very limited, and we still have no clue how the graviton works in Thirteen, but we are very rough to use the peripheral firing device to carry out directional excitation of the graviton it collects, which can only be regarded as an application today, far from understanding.

And its core components can't be disassembled at all with our capabilities, so ......"

The district chief began to feel more and more uneasy when he heard this, this situation does not need to be asked, he knows that it will definitely not be a good thing, he is now convinced of Jay's inference, otherwise where in the world is there such a coincidence?

You must know that the United States accidentally obtained this alien artifact from a geological change in Yellowstone Park 10 years ago, and it has always been very well-behaved, not noisy and not noisy to cooperate with them in the experiment, and there is no abnormality at all.

How could it be that there would be no accident sooner rather than later, but as soon as Captain Ghost started it, it had a problem, and if he wanted to say that it had nothing to do with aliens, he wouldn't believe it!

"Damn! I want to know now, what can you do to make it stop! The district chief shouted.

"This ...... We're trying to figure out how to ......," the researcher said, with some lack of confidence.

"What about wrecking it?" Jay, who had been silent, said something that made everyone's hearts skip a beat.

If it weren't for the fact that this sample was so precious, they wouldn't have dared to disassemble the core components violently, and despite the precautions, accidents still occurred......

But to say wreck it...... The district chief hesitated!

This is the only thing that can understand the technological level of aliens, and even make major technological breakthroughs, and that is the super technology of "graviton"!

At present, they are only able to launch a linear gravitational wave with rough directional excitation, exerting dozens of times the gravity of all targets in their path, although the farther the attack distance, the weaker the power, but it is still the strongest superweapon in the hands of the United States!

If you can give them a few more decades, when you can fully analyze the application of this "graviton", maybe you will have the power to fight the aliens!

That's it...... I'm going to get angina......

The district chief looked puzzled.

"I'm afraid...... We can't do that now......" The researcher suddenly smiled wryly when he heard Jay's proposal to destroy "Thirteen".

"What?!" The two were stunned.

The district chief reacted, "You mean that stance shield?!" ”

The researcher nodded, "We've tried many ways to break the Stand Shield, including heavy machine guns, laser rays, and various cutting devices. But it's useless, it's stronger than we think, and I'm afraid that even a nuclear explosion may not be able to help it!

This is a new, never-before-seen way of using 'gravitons' – the Stance Shield! ”

"It turned out to be ...... This kind of thing! "Both the mayor and Jay were shocked.

"Well, even if we can't help it for the time being, what is it going to do?" Jay asked.

"Based on our previous experience, it seems to be in the preparation stage of collecting 'gravitons' in full force before excitation, and the Stand Shield is just this imagination, and this time the preparation time is quite long.

At the same time, it is actively collecting gravitational data from its surroundings. ”

"Collecting gravitational data around you? What is it used for? The district chief asked.

"It's unclear, but it's strange that the display on the peripherals gives the exact time the data was collected...... 24 hours! ”

"24 hours? Earth time? ”

"That's right! That is...... The time it takes for the Earth to rotate around for one time! ”

"Huh? What do you mean? Their hearts jumped.

"I'm afraid that the data it collects is the gravitational environment data of the entire Earth's periphery...... Then the effect of its excitation may be...... Global! The researcher had a bit of a hard time.

"Goo!" The two swallowed in unison.

Isn't the Earth...... Pill?
