Hundreds of thousands of kilometers away, the huge monster of Jupiter is quietly watching here, as chaotic as ever. In the distance, the huge rings of Jupiter are quietly moving, and more than sixty moons rise and fall in them. Xiao Yu couldn't find anything in the Jupiter system that could cause strong radiation.

If it weren't for the fact that Xiao Yu had deliberately strengthened the spacecraft's thermal insulation layer and anti-radiation layer before his arrival, at this moment, it is estimated that Xiao Yu would have been completely out of order by this anomaly, and the central computer was short-circuited and died directly.

But even so, Xiao Yu was very uncomfortable. Above the ship, there were already some places where subtle sparks erupted. If not dealt with in time, it may cause a larger short-circuit of the line, which can be dangerous.

Thousands of sensors scattered throughout the ship's hull began to collect data with all their might, and various detection equipment such as Geiger counters, magnetometers, photometers, and spectrum analyzers started at full strength, and countless data were transmitted to Xiao Yu's brain and began to calculate.

Almost instantly, Xiao Yu came to a conclusion.

"No redshift? Also not blueshifted? How is this possible? This conclusion made Xiao Yu unable to figure it out.

If there is radiation, there will inevitably be a source of radiation. According to the Doppler effect, when you move away from the radiation source, the radiation band will move towards the red end, that is, the red shift, and vice versa, when you get closer, the blue shift will appear. However, Xiao Yu's current observation is that there is neither a red shift nor a blue shift.

This suggests that the radiation cannot have come from Jupiter. Because Xiao Yu is now moving away from Jupiter, or Jupiter is moving away from Xiao Yu, if the radiation is coming from Jupiter, then Xiao Yu should observe the redshift.

Then there is only one possibility, the radiation source maintains the same movement rate as Xiao Yu's spaceship, both in speed and direction. Or rather...... The source of the radiation is simply on top of the ship.

Xiao Yu immediately started the next round of testing.

"The radiation inside the spacecraft is dozens of times weaker than the outside of the spacecraft, and the sensors on the ship's hull detect the most radiation...... Could it be that the radiation is coming from the outside of the ship, no, or is it attached to the outer shell? ”

Xiao Yu immediately activated the optical sensor and carefully inspected the ship's shell. But there was nothing on the ship's hull that wasn't part of the ship's original belongings.

"What the hell is going on with this!" Xiao Yu was anxious, in such a situation, a serious accident might occur if he delayed a little longer, but Xiao Yu exhausted his means, but he couldn't detect what the problem was.

"Calm down, you have to be calm." Xiao Yuqiang suppressed the panic in his heart, "The wind and waves like the collision of the wood and the moon have all come over, I don't believe that the boat capsized in the gutter." ”

At this moment, the Geiger counter jumped wildly again, and another powerful source of radiation was observed. The difference is that this time Xiao Yu observed a significant blue shift, which indicates that this radiation source is rapidly approaching him.

After determining the direction, Xiao Yu immediately aimed the optical detection equipment there, but what he saw was only the huge Jupiter slowly rotating, and at most a few meteorites were moving according to their orbits carefree, and there was nothing else.

But the radiation is still gradually increasing, and Xiao Yu is almost scolding.

"What the hell is it? What is it? Xiao Yu was depressed and couldn't figure it out. Suddenly, the optical spectrum analyzer showed that the blue shift of this powerful radiation source was gone.

At the same time, the radiation intensity on the outer shell of the spacecraft has also doubled compared to just now.

This indicates that the radiation source has stopped moving.

"Is there another source of radiation attached to my ship's hull?" Xiao Yu made such a speculation, but no matter how he searched, he could not find any objects that could emit radiation in the visible light band.

According to the current radiation intensity, with two more such radiation sources, Xiao Yu's anti-radiation layer will not be able to withstand it, and at that time, the machinery, instruments, and circuits inside the spacecraft will be seriously damaged, even irreparably damaged.

"Huh?" Just when Xiao Yu was anxious, he noticed a little unusual fluctuation.

He felt that the intensity of the radiation source had increased slightly. It's as if the radiation source is trying to get through the radiation barrier and get inside the ship.

"Does this thing still have its own thinking? Is it life? Xiao Yu was startled, and immediately electrified some of the lines under the radiation protection layer, and under the action of the electromagnetic field, the feeling of being infiltrated disappeared.

The current Xiao Yu has passed the time when he is closest to Jupiter. Right now, Xiao Yu is moving away from Jupiter at a speed of fifty-eight kilometers per second.

"Jupiter is too weird here, anyway, I have already got enough observations, so let's run quickly and get out of danger first." Xiao Yu paid attention and accelerated for another ten seconds, consuming several tons of fuel and accelerating his speed to sixty-three kilometers per second.

However, Xiao Yu sensed the danger again. He also observed a blueshift that symbolized the radiation source rapidly approaching him. This time, it's two different sources of radiation!

"Damn, this is to kill Lao Tzu!" Xiao Yu was shocked, and in a panic, he didn't care that he couldn't see these things at all, so he just took out the laser gun, aimed at the direction of the radiation source in the observation, and launched a laser with maximum power.

The laser flashed away, and in Xiao Yu's observation equipment, the blue shift that showed a radiation source disappeared, and the radiation intensity of this radiation source was also reduced by two percentage points.

"It's weird." Xiao Yu secretly breathed a sigh of relief, but the next moment, the radiation source had a blue shift again.

It was as if there was an invisible creature there, and under the blow of Xiao Yu's laser gun, it paused slightly, and then continued to pounce towards Xiao Yu.

"It's really weird." Xiao Yu cursed and continued to shoot in that direction with the laser gun.

This shot did not weaken its strength. Xiao Yu checked the data, only to find that this thing actually changed its direction and avoided the laser gun's shooting.

Xiao Yu's heart froze, and he immediately turned the muzzle of the gun and re-aimed at the radiation source. The radiation source dodged again, and Xiao Yu aimed again. It's like a policeman, constantly aiming at a robber who is constantly dodging.

Under the continuous laser strikes, the observation equipment showed that the radiation source was constantly decreasing in intensity, but although the intensity was reduced, its blue shift did not disappear.

The laser gun shot for about three minutes, consuming almost a ton of fuel, and finally, the radiation source disappeared from Xiao Yu's observation equipment.

"I've really met a ghost." Although a radiation source was eliminated, Xiao Yu did not dare to slack off, and turned the laser gun around again, aiming at another radiation source and shooting, four minutes later, the other radiation source also disappeared, Xiao Yu breathed a sigh of relief.

Xiao Yu began to think about what this thing was.

First of all, they are invisible, but their presence can be detected by the Geiger counter, the direction and speed of their movement can be determined by the red-to-blue shift, and the radiation intensity can be reduced by the laser gun until it is eliminated.

"It's ...... Creatures on Jupiter? Gradually, under analysis, an astonishing thought appeared in Xiao Yu's mind.

can take the initiative to attack Xiao Yu, and can also take the initiative to dodge the laser gun shot, which seems to indicate that this thing has its own consciousness.

This completely subverted Xiao Yu's previous understanding of the word "life". In the minds of most people, including Xiao Yu, life can be seen and touched, and even the tiniest virus, which only has a basic DNA structure, can be exposed under an electron microscope.

So, how do you define a being that has its own consciousness, can move around, but does not have any mass, is completely transparent, does not emit or reflect any visible light, and the whole body is just a source of radiation?

Time no longer allows Xiao Yu to think. Because Xiao Yu observed that at least hundreds of such radiation sources appeared on a certain Jupiter moon 300,000 kilometers ahead, and they all showed a strong blue shift, which showed that they were approaching Xiao Yu at a very alarming speed, and the approaching speed of the two sides was almost as high as 150 kilometers per second!

At this rate, it only takes half an hour for the two sides to meet head-on!

Xiao Yu's current anti-radiation layer can only resist four such radiation sources at most, if hundreds of radiation sources are attached to the surface of Xiao Yu's spaceship, Xiao Yu's spaceship shell will be melted instantly, the spaceship circuits will all be short-circuited, and the central computer will be paralyzed instantly!

Such a result means Xiao Yu's complete death. Even if the central computer was repaired and turned on again, Xiao Yu would not survive.

Because as soon as the computer is turned off, Xiao Yu's consciousness and spirit will become a piece of code fixed on the storage device, and he will lose his self-awareness.

"Holy!" Xiao Yu scolded bitterly, no longer caring about the consumption of energy, increased the power of the laser gun to the maximum, aimed at that direction, and started shooting.

The laser gun fires powerful lasers at a rate of almost one ton of fuel per minute, but even so, it would take Xiao Yu almost two minutes to eliminate a radiation source. With such efficiency, when they met head-on, Xiao Yu would only eliminate fifteen radiation sources at most.

But what about the remaining eighty or ninety radiation sources?

"That's not going to work." Xiao Yu's brain began to calculate at full power, and in an instant, countless kinds of jihua emerged, which were tested by Xiao Yu one by one, and then abandoned one by one.

Finally, one jihua passed the feasibility test.

"There's only one way, so let's give it a try than sit back and wait."

Xiao Yu sighed, and began to control the robot to quickly transform a metal box, which was attached to the inner wall of the spaceship.

"So let's get started, Radiation Source Capture Jihua!"
