The Klein bottle is not really a bottle, it is just a figurative description of a kind of curved space. Xiao Yu intends to distort the three-dimensional space into the shape of a Klein bottle, and with the help of its indistinguishable nature, without destroying the four-dimensional barrier, it will pass through it.

In Xiao Yu's planning, the bottle body of this bottle will be in a three-dimensional space, and the intersection of the bottle mouth and the bottle body will be within the four-dimensional barrier, so that it can penetrate the bottle body through the fourth dimension and connect with the bottom of the bottle. After the manufacturing is completed, theoretically, Xiao Yu only needs to enter the bottle from the bottom or mouth of the bottle, and then after driving a certain distance, restore the smoothness of the space, Xiao Yu will come to the outside of the four-dimensional barrier, it's that simple.

The principle is simple, but it is difficult to build. It takes a lot of calculations and energy to build a Klein bottle, the curvature of space, the amount of energy required, the accuracy of navigation, the fit with the four-dimensional barrier, and so on, and everything that goes wrong can have extremely serious consequences. At worst, the mission fails, or at worst, it may get stuck on the four-dimensional barrier, that is, half of the hull passes through the four-dimensional barrier, and the other half does not pass through. According to the characteristics of the four-dimensional barrier, if this happens, the inner half of the hull will be randomly teleported back, that is, the hull will be split in two. In this way, a spaceship will naturally be destroyed.

If it was the rest of the inconsequential spaceships, it would be better to say, in case the Hebei was divided into two halves, Xiao Yuke would be dead. Even if it was not the Hebei, but another city-level spaceship was destroyed, it would be a very significant loss for Xiao Yu.

Under Xiao Yu's command, countless Lucca scientists began to get busy, and at the same time, Xiao Yu also devoted himself to calculations.

Xiao Yu plans to build a relatively small Klein bottle first. Make a shiyan.

Xiao Yu first created a number of instruments, which decayed into energy with elemental decay, and with the help of these energy sources, they would be able to bend the space to a suitable degree according to Xiao Yu's command.

It was not difficult to build these instruments, and Xiao Yu had already accumulated enough experience and technology by building faster-than-light ships before.

Calculating the curvature of space and building instruments took Xiao Yu a year. There is no way, even if you have traveled to the four-dimensional space and have a lot of knowledge about the four-dimensional space. Calculating these things still takes up too much computing power of Xiao Yu. This is the price of three-dimensional creatures trying to peek into the mysteries of the four dimensions.

But Xiao Yu's efforts have finally paid off. After a year, all calculations were completed and the instrument was built. It was at this time. Xiao Yu ushered in the most critical step in the project.

That is, how to construct one of the most important structures of the Klein bottle within the four-dimensional barrier. How to make the bottle mouth in the four-dimensional space. It is not connected to the bottom of the bottle without passing through the bottle.

One of the characteristics of the four-dimensional barrier is that any matter that comes into contact with the four-dimensional barrier will be randomly teleported back to the galaxy, that is, Xiao Yu cannot arrange any instruments within the four-dimensional barrier, but Xiao Yu still found a way. That is, through the gravitational influence of the gravity bomb, this key structure is constructed.

Through the two previous large-yield gravity bomb explosions, Xiao Yu was sure of one point. That is, the four-dimensional barrier will still be affected by gravity, or the curvature of space, after all, the essence of gravity is the curvature of space. Now that there are means to influence it, it's all well said. Through precise calculations, Xiao Yu created a large number of miniature gravity bombs, through which Xiao Yu will exert influence on the four-dimensional barrier, and inside it, create a passage for the bottle mouth to shuttle.

After making all the preparations, Xiao Yu began to work intensely.

"The third, sixteenth, nineteenth, eighty-fifth gravity bombs were detonated...... Okay, the seventy-first gravity bomb detonated, well, followed by the fifty-sixth and the three thousand five hundred and three......"

Xiao Yu muttered to himself as he manipulated tens of thousands of miniature gravity bombs to explode continuously in milliseconds.

As the gravity bombs detonated, a slight bulge appeared on the smooth surface of the four-dimensional barrier. In the midst of these protrusions, a passage is being gradually constructed.

While the gravity bomb was detonating, the space-bending instrument was also working intensively. They have to be connected to the four-dimensional channel as soon as it is opened. A little later or a little earlier will cause the task to fail.

Thankfully, Xiao Yu's extremely fast and precise computing power ensured Shiyan's success. Amid the cheers of more than 2,000 Lucca scientists, Xiao Yu breathed a sigh of relief.

A small Klein bottle, finally built. Its bottle mouth, through the four-dimensional transformation of the four-dimensional barrier, enters the inside of the bottle without passing through the bottle body, and is connected with the bottom of the bottle.

In front of the instrument that Xiao Yu arranged here, a dark hole appeared. The reason why it is black is because the entrance of the Klein bottle is the exit, it is circulating, which makes it impossible for any light that enters it to come out again, and at the same time, it does not produce light inside, so it is like this.

The black entrance of the cave resembles the mouth of a vicious beast. Whether the front is a new life or a demise, Xiao Yu doesn't know. But Xiao Yu had no chance to back down.

Under Xiao Yu's manipulation, a specially made satellite quietly floated over, and under the gaze of thousands of pairs of eyes, it entered the hole.

As soon as it entered the hole, it disappeared from Xiao Yu's field of vision. Because it has entered a distorted space, and this distorted space will swallow up any light that enters it. In this respect, it has something in common with a black hole.

The rest of the process is entirely up to calculations and the automatic instruments mounted on this satellite.

"Sail time, three seconds." Xiao Yu silently recited, "Three, two, one, zero." haode, turn off the space bending instrument and level the space again. ”

The instrument was turned off. Without the influence of the huge amount of energy, the three-dimensional space that had been bent up immediately returned to flatness. After the space was restored, Xiao Yu found that in this place, the trace of the satellite had been lost.

This means two scenarios. First, the satellite has broken through the four-dimensional barrier and reached beyond the barrier. The second is that the satellite is randomly teleported into the galaxy.

Xiao Yu had expected this situation for a long time, so Xiao Yu was not in a hurry at all, but waited silently.

On top of this satellite, there is a preset program. The purpose of this program is to automatically broadcast a message thirty seconds after entering the Klein bottle. This piece of information will allow Xiao Yu to locate it.

If it is still in the interior of the galaxy, Xiao Yu can naturally find its traces through this information, even if it crosses the four-dimensional barrier, because of the four-dimensional barrier's characteristics of allowing entry and not exit, Xiao Yu can still receive its signal.

It's getting closer and closer to the scheduled time. These thirty seconds of time, like the final judgment from the gods at the end of the world, lifted the hearts of Xiao Yu and all the people who knew about Luca.

Thirty seconds passed, and Xiao Yu's instrument arranged in space received the signal as scheduled. After receiving the signal, Xiao Yu immediately analyzed it.

More than 2,000 Lucca scientists are still waiting for news. is waiting for Xiao Yu to tell them, the news that can determine their life and death.

The completion of this series of projects took Xiao Yu three years. Xiao Yu still has a total of ten years left, and Xiao Yu's fuel reserves are only enough to last another five years. In other words, if they fail again this time, Xiao Yu and Luca will not have a second chance.

Xiao Yu's four-dimensional trembled, and he imported this data into the program, waiting for the final result to be judged.

It only took a ten-thousandth of a second for Xiao Yu to get the answer.

"The satellite is at a distance from the central stellar mass...... Seven hundred seventy six million three thousand two hundred thousand kilometers! ”

"Whew." Xiao Yu exhaled softly.

At the present moment, the distance between the four-dimensional barrier and the central stellar mass is 7,640,03,100 kilometers.

Its distance is less than the distance between this moon and the central star.

The result is self-evident, that is, this satellite is outside the four-dimensional barrier at the moment.

In the auditorium, Xiao Yu's phantom slowly turned around, and his face opened his mouth expressionlessly.

"The results are in. We...... It worked! This satellite has successfully reached the outside of the four-dimensional barrier! ”

This sentence, like a cannonball, exploded in the auditorium. In the auditorium, there was a terrible silence at first, and it took more than ten seconds before a little noise came.

But these voices were not cheers, but constant weeping.

The two most brilliant scientists, Luca III and Luca IV, collapsed to the ground first, as if at this moment they had lost all their strength, their faces were full of tears, they looked up at the ceiling, and muttered to themselves: "Finally succeeded, finally succeeded!" ”

Sixty years of struggle! Countless hard work, countless sacrifices, and countless sleepless nights have finally paid off in return.

"We succeeded, we succeeded!"

In this moment, the auditorium transforms into a sea of joy. After the initial excitement had passed, thousands of Lucca scientists jumped up with cheer, their voices still choked, their faces still with tears, but their expressions were clearly laughing, laughing with joy.

They jumped, laughed, and hugged each other. Xiao Yu couldn't help but smile on his face.

It's a cheer for a new life, it's a cheer for never giving up the struggle has been rewarded! (To be continued......)
