Global Famine: My items can be automatically upgraded

Gravitational lens?

This term made Shen Bei's mind a little confused.

It felt familiar, but the specific definition was completely unknown.

Just like many people know that the earth has gravity.

But what gravity is, no one can explain it systematically.

However, Shen Bei can throw the questions he doesn't understand to Lingxi Zhiling.

Super artificial intelligence!

Before castration, it was humanized!

To be frank, when the SP module was created, its function was not much worse than Dr. Batu.

So, Shen Bei asked: "The explanation is, what is a gravitational lens."

For Lingxi Zhiling, this question is as simple as 1+1.

It doesn't take much computing power to give a relevant definition.

Of course, if the SP module before castration had not been castrated, Shen Bei would definitely be asked why this question occurred.

Also, he would definitely ask why the Tiangong suddenly became larger...

Why hundreds of space suits appeared out of thin air in the warehouse.

This is the disadvantage of humanization, and it is necessary to ask clearly.

But now, the SP module is an artificial intelligence, completely oblivious to the changes in Tiangong.

This makes Shen Bei much less worried. ,

There is no need to intrigue with artificial intelligence.

Soon.

An electronic voice came from Lingxi Zhiling:

"In simple terms, gravitational lensing means that when starlight passes around a massive star, the light that originally propagates in a straight line will bend due to the gravity of the massive star, and it looks like the position of the original star has shifted slightly."

"The earth will also experience gravitational lensing. However, on a cosmic scale, the mass of the earth is still too small, and the gravitational lensing effect may be negligible, which means that a very high-precision instrument is needed to observe in which direction the gravitational lensing phenomenon occurs."

Shen Bei said.

Half-understood.

So, what exactly does gravitational lensing do?

Shen Bei asked again: "What is the use of installing a gravitational lens on a spacecraft?"

Lingxi Zhiling made a brief analysis and made a guess: "The current weight of Tiangong is 100,000 tons, and it does not have the phenomenon of gravitational lens. If the assumption is true, Tiangong will produce the phenomenon of gravitational lens, then the only possibility is that Tiangong is not at the current coordinates and position when others observe it."

Shen Bei touched his chin and thought for a while.

The answer given by Lingxi Zhiling is closely related to the concept of gravitational lens.

But it is more general.

According to Shen Bei's understanding, to use an appropriate metaphor, it is like fish in a stream.

When people observe on the shore, the position of the fish is always deviated by some distance due to the refraction of the water.

If a person holds a fork and tries to catch a fish according to the current position in the field of vision, it will inevitably catch nothing.

It is necessary to deviate a little to find the real position of the fish.

It is easier to understand if it is replaced by a gravitational lens.

If Tiangong is suspended in the air, the position within sight is a piece of water.

Under the effect of gravitational lens, it is not the current position of Tiangong, and a shell fired can only hit nothing...

"Not bad!"

After Shen Bei figured it out, he rubbed his hands: "This function is good!"

It is a good thing to confuse the enemy and make a fatal attack.

After a while of excitement.

Shen Bei started his "handmade" business again.

Continuously pry open the bottom shells of various types of shells and take out the gunpowder.

Tiangong continuously produces shells, and launches them recklessly in the flying wilderness to gain experience points.

...

Time passes.

Ten days later.

Tiangong is upgraded again.

This time, the new changes did not arouse Shen Bei's great interest.

What interstellar missiles, various laser weapons.

It looks really awesome, and it is definitely a killer within the range of the earth.

But Shen Bei has a hunch that if he really turns against the world-destroying starship and the Shadow Immortal,. '

The battlefield of the three parties may be transferred to the universe.

After all, the earth is too fragile to withstand the bombing of three huge spaceships.

So, the disadvantages came out.

For example, the fastest speed of interstellar missiles is only a few thousand kilometers per second, which is too slow in the space where the distance is often calculated in millions of kilometers. Moreover, although interstellar missiles are powerful, they are easily intercepted by laser cannons.

Secondly, there are various laser weapons. This kind of weapon also has its limitations, that is, it consumes a lot of energy and has a small attack range. But it also has its own advantages, that is, at this stage, in space, laser weapons are almost impossible to defend.

The beam emitted by laser weapons is not visible light in the usual sense, but invisible light with extremely high frequency, so it cannot be reflected by mirrors. The only means of defense is to block it with something to prevent it from directly shining on the hull.

At the same time, Shen Bei also moved all kinds of equipment in the military base.

Throw it all to Tiangong.

Various production lines have also been built.

Another half a month passed.

Tiangong was upgraded again to LV10.

The overall length of the spacecraft has exceeded 50 kilometers.

It is almost comparable to the world-destroying starship.

During this upgrade, Tiangong acquired the technology to produce satellites.

Thousands of exploration satellites were also produced by Shenbei.

These satellites are extremely small and have extremely simple functions.

The small size is for easy concealment, and the simple function is because they only need to undertake the detection function. Shen Bei does not expect these satellites to strike the enemy.

When the space war occurs, these satellites will become Shen Bei's eyes and collect various battlefield intelligence for Shen Bei.

In addition, Shen Bei has also transformed a large number of small missiles. These missiles are made of highly concealed materials. Their volume and mass are only a few hundredths of those of interstellar missiles, and their warheads use conventional high-explosive ammunition.

This means that although they are far less powerful than hydrogen bombs, they will have extremely high concealment and flexibility, and they are cheap and can be manufactured in large quantities.

Shen Bei stayed in this military base for almost a month.

After emptying all the shells inside.

As for firearms, Shen Bei also equipped Xiao K with a few, so he can play with them when he has nothing to do. Although Xiao K can't play...

But it is more or less a means of attack.

The upgrade of Tiangong has come to an end for the time being.

Counting the time, from leaving Shelter No. 36 with Xiao K on his back, to Shelter No. 20 of Song You, to Shelter No. 5 of Baba Tu, and then living in this military base.

This time Shen Bei went out, it took almost half a year.

Just when Shen Bei was about to set off to return to Shelter No. 36.

Lingxi Zhiling suddenly heard a voice:

"Capture the radio signal, do you want to crack and listen?"

Radio signal?

Shen Bei tilted his head, which can allow radio signals to be transmitted in the wilderness.

That is, the collective "online meeting" of each shelter

In Shen Bei's view, the online meeting is just a place for the leaders to spit and scold each other.

There are a lot of garbage information, and very little useful information.

However, Shen Bei has nothing to do.

After packing up the armor and guns and making sure that nothing is left behind, he walked out of the military base.

Order: "Crack it, or listen to the quarrel."

Shen Bei has not heard human voices for a while.

Although Lingxi Zhiling is smarter than humans in some aspects, it lacks the agility of humans after all.

Soon,.

Lingxi Zhiling cracked the radio wave and cut into the online meeting.

Instantly.

A noisy voice sounded in the visual helmet:

"My godmother! Shelter No. 17, are you still a human? The supplies I want are empty boxes? If you don't give me an explanation today, I will declare war on you!"

"Fuck, don't frame people, our supplies were all fine when they were delivered, there must be a ghost among your people!"

"Stop arguing, are you annoying, is You Wuchang online? What's the situation on your side?"

As soon as this sentence came out, the radio was immediately silent.

Shen Bei heard the voice of this sentence, it was none other than the famous Spider Queen!

The next moment.

You Wuchang's voice sounded: "Everything is going according to plan."

As soon as this was said.

The radio was noisy again, and the voices of many people were talking...
