By the way, those shielding experiments, this experiment designed by myself, is to find a material that can really shield death rays.

As long as you find a really useful shielding material, then you can find a way to further weaken the dose of death rays that enter the battleship.

Due to the presence of human warships and spaceships, there are as many as 12 types of radiation protection or shielding layers.

In order to be able to confirm which shield has an effect on death rays, or the effect of the effect, Li Chunfeng used 12 warships, set up only one layer of shielding, and placed experimental animals.

Today, not only did the experimental animals in the battleships without the shielding layer die, but the experimental animals of 10 battleships also died, and only two battleships did not have experimental animals.

But the experimental animals in one of them seemed to be in a vegetative state, as if their brains were no longer functioning. The animals in the other ship also seemed to be a little sluggish.

Li Chunfeng found that the shielding layer laid by the two warships was a new type of tungsten alloy plate reinforced by strong force, and the other material was a lead-silver alloy plate reinforced by strong force.

In the battleship with a shield made of new tungsten alloy plates, the experimental animals were somewhat sluggish, but there were no functional disorders.

In the battleship with a shield made of lead-silver alloy plates, the experimental animals resemble humans who have become vegetative beings, as if their brains are no longer functional, and the animals are unable to survive on their own.

It seems that the new tungsten alloy plate can shield the death rays, but Li Chunfeng found that although this shielding layer can be shielded, there are still higher doses of death rays in the battleship, and if the experimental animals continue to stay, they will still be unable to escape death.

Li Chunfeng was in his heart, if this is the case, will the humans in the battleships and spaceships be able to survive safely for a long time?

After all, the supernova explosion continues, and it will take another 2 days for the battleship to complete the repair of the energy device of the space jump.

The point is that even if the space transition device can be used, if it cannot jump more than 100 light-years, then it may not be able to avoid this death ray, because scientists who studied supernova explosions in the previous Earth era believed that the impact of supernova explosions would be affected within 100 light-years.

This means that the space transition device should make at least 31 full-power jumps, and the entire fleet should make 31 full-power space jumps, which the current energy reserves simply cannot support.

Li Chunfeng thought about it for a while, and decided to think of a way before the space transition device was restored, if there was a way, maybe he would not be able to jump so many times.

At present, the spacecraft and warship where the human race is located have 12 layers of shielding, and compared with the dose intensity of death rays inside and outside the battleship, it is obvious that the composite shield plays a stronger shielding role.

Therefore, Li Chunfeng immediately instructed the wisdom of each battleship to continue to manufacture these two alloy plates, and once again add a layer of double alloy plate shielding to the battleship or spaceship.

After Li Chunfeng mobilized a large number of robots, the people in the spaceship and warship finally became aware of it, and some experts in materials had already seen that this was increasing the anti-radiation shielding layer.

I was a little worried about the supernova explosion that was being broadcast.

The robots moved quickly, and all manned warships and ships were retrofitted.

Then, Li Chunfeng compared the internal and external death ray doses, and found that the new death ray dose inside the spacecraft had dropped from 29 mSv to 14 mSv.

As the Mind Field Enveloped the entire fleet, the dose of death rays on the exterior of all warships also dropped significantly, from 200,000 mSv to 90,000 mSv.

Obviously, the effect of the mind field cover is very effective, but it still can't be completely counteracted, but at this time, Li Chunfeng didn't dare to remove it, given that most of the warships were intelligent warships, Li Chunfeng controlled the idea field to shrink to only envelop manned warships and spaceships.

It was only the explosion of the energy of the right consciousness body to envelop the entire fleet of the thought field, and now that the thought field is very effective, of course, it must be used sparingly. At this time, every additional dose of weakened death rays means the safety of all human beings in the Empire.

It's just that I've been laying out the mental field cover all the time, and I don't know if my consciousness body energy can support it?

It suddenly occurred to me that my consciousness could devour those death ray particles, so could I use my consciousness body to devour these death rays?

But how can your own consciousness exist in a supercomputer, so how can you come out and devour the death-ray particles inside and outside the battleship?

No, my thinking is a little off, and previous research on death rays has shown that it should be a high-energy positron, which annihilates after collision with electrons in the nerve microtubules of the brain, causing the death of living organisms.

Since it is a positron, you can use other electrons to collide with it and annihilate it.

Li Chunfeng immediately took action and modified a particle beam cannon, which accelerated no longer those high-energy particle beams that mixed atoms, neutrons, and electrons, but a single high-energy electron beam.

At the same time, Li Chunfeng also developed a death ray detector, which can accurately detect the dose of death ray particles in space.

With the cooperation of several super artificial intelligences, Li Chunfeng quickly conducted the first test, the electron beam cannon fired at the direction of the supernova explosion, and when the electron beam rushed out of the muzzle, the death ray detectors arranged in the periphery immediately showed a significant drop in dose.

"It's done!" Li Chunfeng was really happy now, which meant that for the death ray, a high-energy electron beam could be used to collide and annihilate the death ray particles.

So, is it possible to make another high-energy electronic shield yourself? But how should electrons be constrained? Well, through a force field generator, the gravitational pull of an atomic nucleus is simulated, and a large number of electrons are confined to make a kind of electron wall.

This does not require accelerating it, but allows it to wait for the impact of the death ray, like a soul electron in a living body.

Every battleship and spaceship has a force field shield, and Li Chunfeng only needs to make an electron generator that generates free electrons, and then generate a large number of electrons, and then through the force field shield, these electrons are bound to the outside of the invisible force field shield, forming a layer of electrons.

In this way, the death ray particles collide and naturally annihilate.

When the first battleship was renovated, as soon as the equipment was activated, the electronic layer was laid up, and a brilliant halo burst out.

Sure enough, the annihilation of the death ray particles and electrons after the collision will release a certain amount of photons, and this beautiful halo is the last afterglow of the death ray.

With the increase of the power of the battleship's electronic layer generator, the thickness of the electronic layer outside the battleship's force field shield gradually increases, and a gorgeous halo is always presented.

It shows that the supernova explosion continues, and the death ray is also continuously emitted, and Li Chunfeng instantly understands that the so-called death zone that the iceman encountered at the beginning is only the area through which the death ray particles of a supernova eruption pass.

This process continues until the end of the supernova explosion, which lasts for a few hours at the shortest and several years at the longest.

If an area is passed by a stream of death-ray particles for several years, what is it that is not a death zone for lifeforms that cannot be prevented?

In fact, his fleet is now passing through a death zone, but this death zone has just been created.

It also means that if you don't leave as soon as possible, I'm afraid that the death ray particle stream here will last for a long time.

Even if he now relies on the electron layer to block the damage of death rays, this place is a void after all, and if you stay here for a long time, neither energy nor matter can be replenished.

Fortunately, two days later, the energy system of the space jump device was repaired, and it was possible to leave the area through the space jump.

By the way, the death zone that the Iceman encountered at that time was not as large as 100 light-years, and perhaps the supernova explosion encountered this time did not cover that large area.

Now that we understand the mystery of the source of the death ray, this supernova explosion 400 light-years away, after 400 years of propagation, will it cover an area of 100 light-years calculated by geoscientists?

Li Chunfeng immediately began to calculate, substituting the supernova position obtained by the observation system and the current position of the fleet into some formulas for calculation, and the results finally came out.

Ten light years!

With the Space Jump Device, the entire fleet only needs to make 4 full-power jumps to leave the Deathray Zone. In this way, he completely defeated the attack of the death ray.

Thinking of the tense heart in the face of the death ray in the past day or so, and now seeing the gorgeous halo on the outside of the battleship, Li Chunfeng finally breathed a sigh of relief.

But then came the problem, this void was so vast, there were still 230 light-years away from the nearest star system, Jing Yasu Seven, because of the shortage of energy, it was impossible to continue the space jump, and the fleet could only sail in a conventional way, which was really a desperate voyage.

At the current speed of the Imperial fleet's regular sailing, if its own biotechnology cannot be advanced, even after several generations of death, the Imperial fleet has not yet reached the Seven Systems of Jingju.

But now in the void, there is not enough material to make a new faster-than-light battleship. Unless the original battleship is dismantled, the materials are rebuilt and rebuilt, but this process takes longer than the direct construction of a new battleship, and dismantling the existing battleship means reducing one's combat power.

After all, Li Chunfeng didn't know that terrifying Kunpeng flying machine at all, would it chase after it? When will you catch up?

If the Kunpeng aircraft chases after him and he can't jump in space, then he can only fight, and naturally he can't dismantle the battleship now.

At present, the death ray is no longer a threat to himself, but it is obvious that the civilization level of the Kunpeng aircraft is not low, so there must be other powerful weapons.

Extrapolating from the currently known scientific knowledge, I can speculate on the weapons of the fifth-level civilization at most, and the weapons of the sixth-level civilization may need to be fantasized.

Although the Divine Eye Empire is an empire at the pinnacle of a third-level civilization, and its territory is also vast, there is still no high-level civilization around it.

However, in their computer data, there is a record of the advanced civilization of the constellation Fox, which is presumed to be at the level of the fifth civilization of the Divine Eye Empire.

The Divine Eye Empire believes that the fourth-level civilization can master the application of various forces, and the fifth-level civilization can master the application of space, so the civilization above the fifth level will no longer be limited by the vast distance of the universe.

As for the sixth-level civilization, the Divine Eye Empire has not speculated.

Li Chunfeng's cognition of the level of cosmic civilization is also basically the same as that of the Divine Eye Empire, and the sixth-level civilization should have an understanding and grasp of the origin of matter in Li Chunfeng's view.

It is speculated that the more powerful weapons include gamma ray explosion, death ray, quantum annihilation wave, etc., from these weapons, it can be seen that Li Chunfeng believes that the relics of the fox high civilization discovered by the Divine Eye Empire should be a sixth-level civilization.

Because after studying the information of the Divine Eye Empire, Intelligence One found that the quantum space mines and "lightning" devices they studied were originally obtained from this ruin.

As for the Xiantang civilization's gamma ray burst weapon, it comes from a galaxy in the constellation Hercules, and it is a warrior of the Xiantang civilization 300 years ago, Yang, who led an expedition fleet and encountered a space adventure near the dark clouds of the constellation Aquila, and actually crossed to a galaxy in the constellation Hercules.

There is a level 6 civilization ruin here, where the warrior Jan obtained the gamma-ray burst weapon and obtained some reinvigorating energy, and then magically returned.

Let the Xiantang civilization have a town and country weapon from now on.

"How come you come across the relics of a high civilization!" When Li Chunfeng first learned about this information, he once exclaimed.

Now that he is being chased and killed by the Kunpeng flying machine, there is a faint guess in his heart, maybe there is such an existence in the universe that specializes in killing intelligent civilizations?
