Xiao Yu turned off most of the instruments, covered the most important instruments that could not be turned off, such as the central computer, with high-barrier anti-radiation materials, and then manipulated the laser gun, randomly aimed at one of the radiation sources, and started shooting.

The shooting lasted for thirty seconds, and this radiation source was dodging, and after a pause, it opened a distance of nearly 2,000 kilometers from the radiation source army, and then, Xiao Yu changed the target, aimed at another radiation source, and so on.

Under Xiao Yu's conscious control, one by one, the radiation sources left the large army, separated from each other by a certain distance, and the radiation intensity was weakened to varying degrees. In just ten minutes, Xiao Yu consumed hundreds of tons of fuel, which made Xiao Yu's heart ache.

But the consumption of these fuels is worth it, because in such a situation, Xiao Yu does not have to worry about the situation of these radiation sources rushing up.

By the time Xiao Yu had made all the preparations, the nearest radiation source was less than three thousand kilometers away from Xiao Yu. According to estimates, it will only take thirty seconds at most for Xiao Yu to meet this forward radiation source head-on.

Xiao Yu began to quietly wait for the moment of meeting.

Under the effect of inertia, the ship quickly moved forward. Ahead, there were hundreds of powerful radiation sources lining up and rapidly approaching Xiao Yu. At the moment when the two sides came into contact, this strange radiation source was like a locust meeting fresh flesh and blood, desperately sticking to the shell of Xiao Yu's spaceship, desperately squeezing inward.

The temperature of the ship's hull rose to 200 degrees Celsius in an instant, and it continued to increase.

Xiao Yu gritted his teeth and opened a gap in the ship's hull just as the next radiation source was about to approach.

The gap is just opposite the metal box that Xiao Yu had already prepared.

The metal box, up to two decimeters thick, is made of high-strength radiation-resistant and heat-resistant materials except for the side that comes into contact with the ship's hull.

If you only talk about radiation protection and high temperature resistance, this box is more than 100 times higher than the hull of a spaceship.

So, the radiant source that had suddenly found the vent poured into it with a cheer, and then, blocked by the stronger barrier of the metal box, could not move any further.

A radiation source is confined in a box. And then there's the next one.

Everything was as expected, and the radiation source was smoothly locked in the box.

These radiation sources, while exhibiting certain characteristics of life, do not appear to be intelligent, but rely solely on instinct to act. At the very least, they won't tell if there's a trap ahead.

It is precisely because they have no wisdom that Xiao Yu's jihua can work.

Gradually, all the sources of radiation entered this box. Sensing that the temperature of the spaceship's shell was rapidly weakening and the radiation intensity was also rapidly decreasing, Xiao Yu breathed a sigh of relief and turned the instrument that had been turned off before.

The radiation source captures jihua successfully.

At this time, Xiao Yu was already 600,000 kilometers away from Jupiter.

Xiao Yu breathed a sigh of relief in his heart, and while manipulating the spacecraft to quickly leave Jupiter, he manipulated the instruments and began to analyze these strange radiation sources that showed certain characteristics of life.

At this moment, these radiation sources were crowded together on the inner wall of the metal box, refusing to leave for a moment, as if something outside the box was attracting them.

"Through the previous phenomena, it can be basically determined that they have instincts similar to those of living beings, and they should not have wisdom, otherwise they should not be so stupid. So, let's say they're creatures, but what's on my ship that attracts them? ”

Xiao Yu thought quietly, "Before the destruction of the earth, human beings also launched several Jupiter probes, but they did not encounter such strange creatures, that is to say, these creatures were created in the near future, well, the most likely situation is that after the collision of the Jupiter moon." ”

Xiao Yu analyzed slowly, and clues flashed in his mind.

"What the hell is there on Jupiter that is not on my spacecraft? It must have been something like this that attracted them and made them rush towards me like a swarm of bloodthirsty locusts. ”

Xiao Yu confirmed this speculation.

"No matter, let's keep them locked up first, and then analyze these guys after we get to Titan and establish a solid base."

Finally got through this big crisis, Xiao Yu had a feeling of seeing the light of day again, and at the same time, he also felt a truth more profoundly.

The universe is endless, and even in a small solar system, there are so many incomprehensible existences. In the face of great nature, it is better to remain in awe.

At the same time, Xiao Yu also knew that he was no longer the only creature in the solar system. At the very least, there are hundreds of suspicious creatures accompanying him in the boxes inside his spaceship.

While assessing the damage caused by this encounter, Xiao Yu slowly slowed up the spaceship. Suddenly, Xiao Yu noticed something unusual.

"Huh?" Xiao Yu pointed the detection equipment at the box a little strangely, and looked at the data fed back, Xiao Yu was surprised.

The original chaotic hundreds of radiation sources are gone, replaced by a single radiation source that is hundreds of times more powerful than the previous individual radiation source!

These radiation sources are combined into one.

Thankfully, even if it were to merge into one, the total radiation intensity was not greater than it had been when it had been dispersed, but seemed to have decreased slightly. So this box can still continue to imprison it.

But Xiao Yu noticed a peculiar change again.

The metal material of this box, under the influence of this strange radiation source, seems to have changed a little.

Xiao Yu's heart tightened, and he immediately analyzed this box.

Seem...... It is a little denser, the molecules are more densely arranged, and the temperature on the outside of the box is gradually decreasing, and the radiation that can be detected on the outside of the box is gradually decreasing. This means that the box keeps more heat and radiation inside the box. This shows that the metal material that makes up the box has been strengthened in terms of thermal insulation and radiation resistance for some special reasons.

Xiao Yu was in good spirits, and immediately manipulated the robot to cut a little material on the outer wall of the box, and took it to the laboratory to start the test.

Shiyan results came out quickly. The results show that in this short period of time, the thermal insulation and radiation resistance of the metal materials that make up the box have increased by fifty and forty-five percentage points, respectively! At the same time, its flexibility and resistance to hits have also taken a leap forward.

"I didn't expect that these weird things are still treasures." Xiao Yu let out a long exclamation. The miracle of the creation of the universe once again brought him great shock.

Previously, there were two reasons that restricted Xiao Yu from carrying out real interstellar travel. One is the power problem, and the other is the material science and technology problem. As long as the barrier of controllable nuclear fusion is broken, the power problem will be perfectly solved, and now, material technology has also been seen by Xiao Yu at the dawn of the solution!

Although we are only seeing a little sign of it now, and we are still far from a complete solution, we are at least seeing hope now. It can be said that if Xiao Yu can't solve the problem of material technology, Xiao Yu will always be in a situation where a small meteorite can kill Xiao Yu. It is inconceivable to embark on an interstellar voyage in such a state that can easily travel hundreds or thousands of years.

Moreover, if the material technology problem is not solved, Xiao Yu's spacecraft will always remain small in size, and it will never be able to land directly on the planet. Otherwise, as soon as he gets close to the planet, its gravitational pull will tear the entire spaceship apart, and even if he lands on the planet, Xiao Yu will never be able to fly again.

This is the shackles of material technology. Now, material science and technology has also got the hope of being solved, how can Xiao Yu not be excited?

"The so-called loss must be gained, and now it seems that my interstellar voyage Jihua has great hope." Xiao Yu thought excitedly, "Just wait until you land on Titan, then build a large-scale base, research all the new technologies, and then develop a new generation of interstellar spacecraft and set off towards Tianyuan IV!" ”

At the same time, Xiao Yu began to consider whether to return to Jupiter and try to capture some of such strange radiation sources. After all, with the property of improving the performance of materials, the value of these radiation sources is not ordinary.

Just as he was about to move in his heart, Xiao Yu suddenly observed a collection of radiation sources that were hundreds of times more powerful than the previous hundreds of radiation sources, and moreover, they were showing a blue shift!

Blue shift, which means that they are approaching Xiao Yu. And Xiao Yu's current speed, relative to the Sun, has reached 60 kilometers per second, and relative to Jupiter, it has reached a speed of 70 kilometers per second. According to calculations, the velocity of these radiant sources is at least 80 kilometers per second relative to Jupiter!

At least tens of thousands of single radiation sources! This kind of intensity, no matter how much Xiao Yu is jihua, no matter how much he prevents it, it will not play a role, if he is caught up by these radiation sources, Xiao Yu will definitely be melted away immediately, and become an interstellar meteorite wandering in the vast universe forever.

Xiao Yu's frightened soul flew out of the sky, and immediately put Jihua, who had returned to Jupiter and recaptured some radiation sources, put it on the back of his mind, started the acceleration again, and flew away in the direction of Saturn in a puff of smoke.

After watching the blue shift gradually disappear and making sure that he had escaped the pursuit of these strange Jupiter creatures, Xiao Yu calmed down and thought hatefully: "Anyway, Lao Tzu has already captured some radiation sources, and after arriving at Titan, he has developed a controllable nuclear fusion jishu, and then break through the shackles of material technology, Lao Tzu will definitely come back again to catch you!" ”

"I'll definitely be back!"
