Super Battleship Reborn

This village-level spaceship was still accelerating, until it reached three times the speed of light before stopping.

Three times the speed of light is the highest speed Xiao Yu can currently achieve.

Fifty years later, the radius of the four-dimensional barrier has shrunk from 10 billion kilometers to 7.5 billion kilometers. This means that starting from the center of the galaxy, at the speed of this village-level spaceship, it only takes two and a half hours to complete this long distance.

The way of curvature drive is different from conventional navigation. The biggest difference is that conventional navigation can sail by inertia after the initial acceleration stage, which can save a lot of fuel. But in the curvature drive, since the motion of the spacecraft is zero, there is no inertia naturally, so it cannot rely on inertia to sail. This means that during the voyage, the elemental decay engine must always be running to provide energy for the curvature engine.

This causes the energy consumption of curvature navigation to be much higher than that of conventional navigation. If there is no element decay technology, curvature navigation is simply a magic mirror in the water, which cannot be realized.

This feature has advantages and disadvantages. The disadvantage is that the energy consumption is too large, and the advantage is the leap in mobility.

A spaceship traveling in the way of curvature navigation can either accelerate from rest to the speed of light within ten seconds, and return from the speed of light to rest within ten seconds.

To put it in a less precise way, the maneuverability of Xiao Yu's spacecraft has increased tens of thousands of times compared to before.

An hour later, the ship used the curvature drive method and drove to the edge of the four-dimensional barrier.

After entering the stage of faster-than-light navigation, matter will disappear in the whole wave band, whether it is visible light, ultraviolet light or infrared light, it cannot be seen. After Xiao Yu's research, Xiao Yu believes that this is because the red shift is too severe, causing the light to move out of the detectable frequency. But by detecting the degree of space distortion, Xiao Yu can accurately locate it.

Similarly, during superluminal voyage, because the blue shift is too severe, all the external light is completely invisible.

That is to say, during the superluminal voyage, this spaceship is completely isolated from the outside world.

This will bring certain dangers to super-light travel, because during the flight, the spacecraft cannot detect whether there will be obstacles in front of it. It is okay to say that a short-distance flight will cause accidental collisions if it is a long-distance flight. Like crashing headfirst into a star or planet.

In fact, it is not that the spaceship traveling at the speed of light cannot receive or emit light, but because the redshift or blueshift is too severe, it cannot detect such light. In this regard, Xiao Yu is already conducting research, trying to develop an instrument that can restore the frequency of light so that he can detect external intelligence while traveling at super-light speed.

But at the current stage, this instrument has not been successfully developed, and Xiao Yu needs to continue to conduct uninterrupted research and spend some effort to develop it.

After the spaceship reached the vicinity of the four-dimensional barrier, all Xiao Yu's attention was focused here.

Because he didn't understand the characteristics of the four-dimensional barrier, Xiao Yu didn't know how to break through this barrier. But in Xiao Yu's speculation, super-light travel is likely to break through. Now is the time to test whether Xiao Yu's conjecture is correct.

Collision will happen in five seconds. Five, four, three, two, one...

In the field of view of the space distortion detector, the village-level spaceship suddenly disappeared.

Has the breakthrough been successful? Xiao Yu was thinking a little nervously, and immediately commanded the village-level spaceship to escape from the superluminal flight through the long-distance communication method, and immediately began to use the instruments on the spaceship. , and start to detect the external environment.

Into the eyes, is nothingness, nothing.

Where is this? Xiao Yu thought in a daze, Could it be possible to break through to another space by traveling faster than the speed of light? This is too ridiculous.

Xiao Yu manipulated the village-level spaceship to continue the detection, and then, in the space background, the light red barrier caught Xiao Yu's attention.

It was an extremely huge red barrier that occupied the entire field of view of the detection instrument.

Xiao Yu's heart gradually sank to the bottom.

The detection instruments of the village-level spaceship turned around, and sure enough, this huge red giant star was detected. After this village-level spacecraft sent out a burst of radio waves, the satellites scattered throughout the galaxy quickly located it with the help of this burst of signals.

As a result, this superluminal spaceship still hasn't broken through the red barrier. Like the other spaceships, when it touched the barrier, it was randomly teleported to a point between one billion and one billion kilometers away from the central star.

Experiments have proved that traveling faster than the speed of light cannot break through the four-dimensional barrier.

I should have thought about it a long time ago. Facing the four-dimensional barrier, super-light travel is not enough. Xiao Yu muttered to himself, If you can break through the four-dimensional barrier just by super-light travel, then there is no four-dimensional protective cover. What is the value of using it? After all, a fourth-level civilization that has mastered the super-light speed navigation technology may not be able to develop super-light speed kinetic energy weapons. If even super-light speed cannot be defended, the value of the four-dimensional protection cover is not as good as the force field shield. The value of the cover is great.

So, how can we break through the four-dimensional barrier?

Xiao Yu fell into a daze.

The decay of elements and faster-than-light navigation are the biggest technological breakthroughs Xiao Yu has made in the past few hundred years. Moreover, it is foreseeable that Xiao Yu will not be able to achieve other major technological breakthroughs in the next few hundred or even thousands of years.

If Taihao is kind to me, then it is impossible to create a barrier that cannot be broken through by the technological level of a fourth-level civilization. In other words, under the premise that Taihao is kind to me, breaking through the fourth dimension The technology of the barrier must be in the technological system of the fourth-level civilization. However, it is not even faster than the speed of light, so what is it? After all, faster than the speed of light is the most prominent feature of the fourth-level civilization.

Xiao Yu pondered slowly, Perhaps, it will be an elemental decay bomb? Or a material disintegration ray? Or a large number of superluminal kinetic energy weapons bombardment?

At this moment, Xiao Yu felt that he suddenly lost the direction of his struggle.

It is impossible to break through to level 5 civilization in a short period of time. Not only that, but in the remaining less than 150 years, it is impossible to make another major technological breakthrough. Then Xiao Yu can only rely on the technology he currently has to try to break through the four-dimensional barrier.

But...the speed of light travel can't break through, what kind of technology is that?

Xiao Yu was thinking with some confusion, This point can only be tested slowly in the future. I hope that I can find a way to make a breakthrough within 150 years.

The radius of the four-dimensional barrier has been shrinking. This is equivalent to a rope around Xiao Yu's neck. When, when this rope is tightened to the point where Xiao Yu can't breathe, it will be the time for Xiao Yu to perish.

But Xiao Yu soon discovered that he was wrong again.

Xiao Yu had been ignoring a problem before.

By chance, a spacecraft's temperature detector found that the temperature of the interstellar space was rising.

Before the appearance of the four-dimensional barrier, in this star system, two billion kilometers away from the central star, the temperature was 137 degrees. At a distance of seven billion kilometers from the central star, the temperature is minus one hundred and eighty-five degrees.

The temperature mentioned here is not a purely physical quantity, but a temperature that can be truly measured.

But now, this temperature has changed. Xiao Yu saw that at his location, the temperature had risen from 137 degrees to 145 degrees without knowing it. At a place seven billion kilometers away from the central star, the temperature had already risen to 145 degrees. It rose to minus one hundred and fifty degrees.

This means that within the four-dimensional barrier, the temperature of the entire star system is constantly rising.

Xiao Yu soon found out the reason.

It turned out to be like this...Because of the existence of the four-dimensional barrier, the heat of this star cannot be radiated out, but can only be accumulated in the galaxy. In this way, the temperature will naturally rise continuously.

After reaching this conclusion, Xiao Yu began to care about another issue. That is, how fast is the temperature rising? When will it rise to a level that cannot be tolerated?

For this question, Xiao Yu quickly found the answer through calculation.

The conclusion is that the temperature will rise faster and faster. After fifteen years, no matter how far away from the stars, the lowest temperature in the galaxy will reach more than 3,000 degrees. And Xiao Yu's spacecraft, in such a temperature, will have to consume more energy to resist the high temperature.

This star system within the four-dimensional barrier will become a veritable steamer. Xiao Yu's spaceship is steamed buns that are constantly steamed in a steamer.

After fifteen years, in the face of rising temperatures, I will use up all the stored energy and have to disassemble the rest of the spaceship as fuel for the elemental decay engine.

But even so, I can't support it for too long. The increase in temperature will only increase the energy consumption. If calculated in this way... After the temperature reaches more than 3,000 degrees, I still have five years.

If I can't break through the four-dimensional barrier, at the last moment, after dismantling all the remaining spaceships, I will have to dismantle the equipment inside the Hebei to obtain energy...

In terms of comprehensive calculation, my time is not one hundred and fifty years, not one hundred years, but only twenty years... In twenty years, I must find a way to break through the four-dimensional barrier, otherwise I will die... ...
