"There are two more?" Xiaotian's eyes lit up.

The three-dimensional space folding teleportation array had already given her a big surprise. She didn't expect that Su Yu would actually exchange it for something?

It seems that Su Yu has done a lot in these seven days!

"What are these two things?" Xiaotian held Su Yu's left arm and kept shaking it.

"Let's go, I'll take you to see it." Su Yu smiled slightly.

With a slight wave of his right hand, a silver-white portal appeared in front of them.

From the portal, you can see that the opposite side seems to be a vast expanse of white.

"Okay." Xiaotian couldn't wait and stepped into the portal.

After walking into the portal, the scenery in front of him changed, and Xiaotian came to another place.

She glanced around and quickly knew where this was.

If you read correctly, this is definitely the North Pole!

The current North Pole is surrounded by a vast snowfield, but in the very center of the North Pole sits a giant Skrull base.

Of course, this Skrull base has long been taken back by Blue Star humans.

Seeing this giant Skrull base, Xiaotian immediately judged that it was the North Pole.

However, Xiaotian's attention was not on the Skrull base, but on a giant white pillar in the base.

There was no such white pillar before.

This white pillar is round in shape, with a base diameter of approximately 2,000 meters.

Now it is "inserted" directly on the tarmac of Skrull Base.

In the past, the tarmac of Skrull Base was filled with transport spacecraft and other aircraft.

Now all the transport ships are gone, replaced by this white pillar.

Although the base of the white pillar is 2,000 meters long, it becomes thinner as you go up.

The pillar went upwards from the apron through the clouds. When it reached the cloud layer, the diameter of the pillar was only about 500 meters.

Xiaotian raised his head and looked at the top of the pillar.

But it was obscured by the clouds, so she couldn't see exactly how high the pillar was.

"Nemesis, Nemesis, what exactly is this? Also, how high is this pillar?" Xiaotian pulled Su Yu's sleeve excitedly.

Su Yu didn't show off and said with a smile: "This is the wonder I was talking about that is comparable to the Traena Sky Tower. Its name is the 'Space Elevator'. As for the height, it is a full 36,000 kilometers!"

"36,000 kilometers, oh my God!... Space elevator..." Xiaotian's eyes were full of surprise.

36,000 kilometers is too high!

You must know that the height of the clouds from the ground is only 10 kilometers, and it is 36,000 kilometers! The part under the clouds she can see is not even one-third of the total height!

This is simply ridiculously high and unimaginably high!

And "space elevator"...she seemed to have heard this name somewhere.

Su Yu flew over to the space elevator with Xiaotianchao, and introduced at the same time: "The space elevator is a relatively basic technology of the Holy Silver Federation.

On the core planets of the Holy Silver Federation, these planets were fully developed hundreds of millions of years ago, and there is no usable space on the surface.

In order to protect the ecology of the entire planet, the Holy Silver people gradually moved their buildings into outer space and built outer space cities one after another.

These outer space cities are connected to the surface of the planet by this kind of 'space elevator', and people living in outer space cities can use space elevators to reach the ground."

"Oh, so that's it." Xiaotian nodded.

She has watched some science fiction movies, and some of those science fiction movies do involve building cities in space.

The Holy Silver Civilization has nearly 500 billion stars and countless planets. It is completely understandable that space cities can be built in the core area.

Since cities can be built in space, it is not surprising to build a space elevator that can connect space cities with the planet's surface.

Su Yu continued with a smile: "This is the space elevator that I spent 2,500 credits to redeem. If we build a space city or space station in the future, we don't need to take a rocket to go to outer space, but just take the elevator directly, which is convenient and fast!"

"Sounds awesome!" Xiaotian's eyes flashed with little stars.

Now the two of them have flown to the side of the space elevator, and what they see is almost all white.

Xiaotian reached out and touched the material of the elevator's outer wall and found that the elevator's outer wall was extremely smooth and elastic.

She experienced it carefully. The exterior wall of the elevator was much smoother than glass. It felt a bit like the smooth and soft texture of a cooked egg after the eggshell was peeled off. She didn't know what material it was made of.

But when she thought about it again, she felt that something was wrong.

"No, Nemesis." Xiaotian tilted his head and looked at Su Yu: "Although it sounds powerful and feels smooth, what is its use? Can we still plan to build an outer space city?"

Now the top priority for humans on Blue Star is to defeat the Skrulls and defend their homeland. What is Su Yu doing by exchanging a space elevator?

It can't be that the coalition government decides to build a city in outer space and then abandon the earth and run away, right?

Su Yu smiled: "The current space elevator is indeed of little use. Let alone the short term, it may not be used for thousands of years in the future."

"and you……"

"The reason why I exchanged this space elevator is because I need to install some devices in the middle of the elevator." Su Yu explained: "These devices are called 'sky shields', and they are mainly used to deal with the Skrulls' satellites.

A total of 36 'sky shields' are installed in the middle of the space elevator, aiming at 36 different directions.

With these jammers, all spy satellites launched by the Skrulls will be ineffective, and they will not be able to detect the current situation on Blue Star.

If you've played the game Red Alert 2, this is equivalent to a 'crack generator' that covers the entire map."

"Sky shield...oh, so that's what happened!" Xiaotian nodded clearly.

It turns out that Su Yu exchanged an entire space elevator for these shields, which is equivalent to making a plate of dumplings for a plate of vinegar.

The shield is the dish of vinegar, and the space elevator is the dish of dumplings.

Su Yu added: "The sky dome shield requires a high amount of electricity and a stable environment to work, and the electricity obtained by using solar power panels is completely insufficient.

That's why we need this space elevator to pull high-voltage wires along the wall and transmit power up.

Although the space elevator cannot be used for the time being, I think it will be available sooner or later in the future!"

"Yeah." Xiaotian nodded: "If you only spend 2,500 credits, redeeming this space elevator is indeed worth the money. At least we won't be monitored by the Skrulls 24 hours a day!"

In the past, the biggest problem for the Blue Star coalition government was that every move they made was completely exposed to the surveillance of the Skrulls.

The Skrulls use the giant base to launch hundreds of thousands of spy satellites. The Blue Star people's military dispatch, material transfer, and even what Speaker Hu Jing had for lunch can be clearly seen by the spy satellite!

This environment is extremely unfavorable for them to deploy defenses.

It’s much more comfortable now that I have a sky blocker.

They no longer have to worry about the Skrulls being able to see their military dispatch, war drills, and material deployment, which is definitely a good thing for the final decisive battle!

Xiaotian gently touched the smooth and soft wall of the space elevator again.

Then she turned to look at Su Yu: "Nemesis, talking about the space elevator, can the space elevator be used now? Can I experience the feeling of taking the elevator directly into the universe?"

Xiaotian wanted to give it a try. She was full of curiosity about this new thing.

"Okay." Su Yu nodded and said, "The space elevator is now available and can take you to outer space 36,000 kilometers away, which is the orbit of geosynchronous satellites.

But the whole process takes a bit long, it takes at least 8 hours from the bottom to the top. If you really want to sit down, I suggest you come back tomorrow to avoid wasting game time."

"Okay then." Xiaotian glanced at the elevator and replied.

She didn't say whether she wanted to take the ride tomorrow morning, because wasting 8 hours of time was a bit too luxurious. Now that the enemy is facing the enemy, she didn't want to waste this precious time, not to mention that there was most likely nothing in space.

…

In the next period of time, Su Yu took Xiaotian to visit the internal structure of the space elevator.

The interior of the space elevator is full of complex mechanical components, so precise that Blue Star people cannot understand them at all.

However, the two of them didn't spend too much time in the elevator. After walking around for a while, the time came to morning.

"Let's just stop here in the elevator. There's still half an hour left. I'll take you to see the last thing." Su Yu took Xiaotian to an altitude of 400 meters in the elevator, and then said to her.

"Okay." Xiaotian nodded immediately, his eyes once again flashed with curiosity.

The first two things she visited - the "Three-dimensional Space Folding Teleportation Array" and the "Space Elevator" gave her great surprises, so what was the third thing? It must be a good thing of the same level, right?

Su Yu waved with one hand, and the silver portal appeared in front of the two of them again.

Xiaotian immediately stepped into the portal.

The scene changed and she came to the next place.

…

Just like the previous two times, Xiaotian immediately knew where they were after passing through the portal.

Because the place she arrived now is too familiar. This is the headquarters of the coalition government on the top of Yanshan Mountain, and she lives in the headquarters now.

"Nemesis, why are you back at the headquarters?" Xiaotian turned back to look at Su Yu: "Could it be that you built the spectacle in the headquarters?"

"No, it's not a spectacle, you see." Su Yu smiled mysteriously and moved his eyes forward.
To be continued...
