At this time, the countries of the earth had fled in all directions, and the fleet of the Aeolian Empire in the three-star system of Nanhe had not yet started.

In the past two months, with the explosion of imperial technology, the warships and spaceships of the Aeolian Empire have undergone some modifications, and their combat power and protection have been improved.

The most important thing is that Li Chunfeng's new Mingjiang-class warships that can sail faster than the speed of light have completed the first batch, with a total of 300 units.

This is the third generation of the Shogun, and its appearance has been slightly changed, and there is a huge ring-shaped device on the outside of the entire disc, but other than that, the size has not been enlarged.

However, it has been completely new inside and out, with strong alloys for its outer shell, armor, and various structural materials.

Such a warship is not only not afraid of the weapon attack of the third-level civilization, but even relying on the collision alone, it can give the enemy a fatal blow with its powerful kinetic energy and quality.

Inside, it has a powerful composite energy reactor that supports powerful curvature engines that can reach one-sixth of the speed of light when sailing conventionally. When traveling in curvature, the speed can reach 50 times the speed of light.

As a first-generation curvature engine, being able to have such an index has already made Li Chunfeng very satisfied, although he doesn't know the average speed of the warship of the fourth-level civilization curvature sailing, but Li Chunfeng is still relatively confident.

At the same time, due to the powerful composite energy reactor, the energy of the warship has been strongly guaranteed, and its various energy-consuming weapons, such as the particle beam main gun with a range of 50 million kilometers, the magnetic energy cannon with a range of 80 million kilometers, and the ice material disintegration ray cannon with a range of 50 million kilometers, can be fully used.

Yes, Li Chunfeng fused the Ice Ray Cannon, which is unique to the Iceman, with the Matter Disintegration Ray Cannon, which can emit two rays at the same time, making the enemy's protective shield even more difficult to parry.

At the same time, the general-class battleship is also equipped with a powerful electromagnetic shield and force field shield.

In order for the battleship to have a more powerful protective shield, even Li Chunfeng has begun to study the energy shield technology, due to the huge consumption of energy by the energy shield technology, Li Chunfeng re-researched the vacuum zero point energy.

When studying the mystery of the "sluggish void", Li Chunfeng solved the situation that there is a strong gravitational source, which causes the electromagnetic force to turn into gravity, but he did not figure out why a strong gravitational source appears in such a void.

If Proxima Centauri is a triad galaxy, there may be a different gravitational problem than the solar system, but in those five years, the mining expedition fleet of the Aeolian Empire has visited more than 20 galaxies, and has found that there are many "sluggish voids".

What particularly surprised Li Chunfeng was that when the locations of these "sluggish voids" were marked, they actually existed around the solar system!

Although Li Chunfeng did not have time to explore all the galaxies around the solar system, these proven "sluggish voids" have also clearly shown that they surround the solar system.

This kind of strange thing, Li Chunfeng originally planned to study it carefully, but now that he is facing a mysterious terrifying enemy, he can only put it aside for the time being.

Perhaps one day, Li Chunfeng will return to the solar system again to study how these "sluggish voids" came about.

However, after Li Chunfeng studied string theory, he knew that if this situation occurred in a vacuum, it was very likely that there was a connection with some space, and the gravitational source may come from an unknown space.

In fact, in the interstellar space, there is a large amount of this kind of energy in this vast and endless void, but it is relatively rare to express it like "sluggish void".

If Li Chunfeng can extract this kind of energy from a vacuum, then he can obtain it continuously, so that it can be compressed by some kind of equipment to form an energy shield.

Such an energy shield is almost impossible to break, unless the attack force frequency is greater than the speed at which the device converts vacuum energy, and its attack stacking power is instantly greater than the converted compression energy, so that this energy shield can be broken.

As for how to extract this energy? In fact, Li Chunfeng has been using it before, that is, the Sail engine, but the vacuum energy extracted by the Sail engine is very small, and it is also very coarse, without some kind of aggregation first, so that the energy obtained is very small.

But with only such a small amount of energy, Li Chunfeng's previous anti-gravity engine has a huge effect.

Through the previous research on the "sluggish void", and now that he has mastered the theory of great unification, Li Chunfeng did not use vacuum energy to generate repulsion like the development of the Thor engine, but directly carried out energy aggregation.

This kind of energy aggregation is controlled by magnetic field, that is, outside the items that need to be protected, through the energy shield generator, two layers of magnetic field barriers are formed at a certain distance from the periphery, and a large amount of vacuum energy is extracted and injected in the hollow of this barrier.

This energy is confined by a magnetic field barrier and does not escape, thus forming a layer of energy barrier.

If there is a physical attack, it will be directly absorbed and sluggish by this shield, thus losing kinetic energy and having no effect.

If it is an energy attack, it will be directly absorbed by this energy shield and turned into a part of the energy shield, that is, the more the enemy attacks with an energy weapon, as long as the attack power cannot break the critical point at once, then it will instead send food to the energy shield.

What bothers Li Chunfeng now is how these two layers of magnetic field barriers can be finely controlled in order to restrain the huge amount of energy.

After all, unlike the electromagnetic shield, it is a strong magnetic field that forms an area, and the control only needs to be done without producing a magnetic field effect on the internal objects.

After failing again and again, Li Chunfeng simply put down this matter and temporarily handed it over to the three great scientists for further research, leaving only a trace of mind to pay attention to.

Li Chunfeng himself began to study the death ray, and only by being able to prevent the death ray could the Wind God Empire have the possibility of fighting a mysterious enemy.

From what is currently known, the death ray should also be a ray formed by some unknown particle, which should only be able to interfere with the magnetic field of life, well, the magnetic field of the planet.

Maybe I should send a warship to explore the several planets that have been attacked, record the magnetic field anomalies of those planets, and maybe find some kind of pattern in them.

Thinking like this, Li Chunfeng's heart moved, and he immediately arranged for several city-level warships to carry some experimental animals to make a space jump to several living planets in the Divine Eye Empire.

As a result of previous search and relocation operations, a large number of early warning satellites and relay communication satellites have been deployed on these living planets.

Therefore, it is very convenient for Li Chunfeng to carry out all kinds of advent and manipulation.

As these warships moved, anomalies in the magnetic fields of various planets were quickly recorded, and the same magnetic field observations and records were made to nearby planets.

Li Chunfeng wanted to see how this mysterious enemy attacked, whether it was a fixed-point attack or a full-coverage attack across the entire galaxy.

A large amount of data was transmitted back through communication satellites, and Li Chunfeng used his powerful computing power to begin to compare and analyze, and soon found some clues.

First of all, this mysterious enemy is not capable of attacking a large area of the entire galaxy, and its attacks are still point-to-point, that is, they can only be carried out against living planets.

Secondly, according to the existing theory of magnetic fields, the magnetic field is generated by a moving electric field, and there are various assumptions for the magnetic field generation of planets.

First, there is a huge iron-nickel permanent magnet core inside the planet, which generates the planet's magnetic field.

Second, the central part of the planetary nucleus "squeezes" out the electrons due to high temperature and pressure, making it positively charged; The outer shell of the planet's core is a shell filled entirely with electrons. This shell is a superconductor, and it is the superconductor's undiminished current that produces the planet's magnetic field.

The third type is generated by a point charge that does macroscopic mechanical motion.

Since the first two hypotheses cannot explain the relationship between the planetary magnetic field and the rotation period of the planet, Li Chunfeng believes that the third possibility is more likely.

It can also be deduced from this that the strength of the planetary magnetic field should depend on factors such as the speed of rotation, the radius of the planet, the thickness of the atmosphere, etc.

Nowadays, the most obvious manifestation of the magnetic field anomaly of the living planets that have been attacked by death rays is that the magnetic field strength has been enhanced.

Under this strength of the magnetic field, the magnetic field in the living body must be greatly affected, but only the strength of the magnetic field is enhanced, and it should not be able to make the living body die silently.

There should be some kind of fatal factor!

This is because mind particles are extremely sensitive to changes in the magnetic field and can control changes in small magnetic fields.

Therefore, in the laboratory, Li Chunfeng selected several different animals to observe their life magnetic field through the mental field, and at the same time applied various rays from the outside that may affect the change of the magnetic field.

It was discovered that the magnetic field of life reacts to the effects of various rays, but none of them are enough to be instantly fatal.

This made Li Chunfeng very confused, what kind of ray can instantly kill countless lives?

Wait a minute, the nervous system is more sensitive to changes in the magnetic field, so could it be some kind of ray acting on the nervous system of living beings, causing death?

By the way, plants don't have a nervous system, will this cause plants to survive under this kind of rays? And those microbes too.

So, Li Chunfeng began to look for what rays could act on the nervous system and kill humans or animals in an instant, or what kind of blow to the nervous system would kill them instantly.

While searching, Li Chunfeng decided to take back the exploration warships of other life planets, and only kept the two city-class ships of the Shenmu Star, the home planet of the Shenmu Empire.

Because according to the trajectory map of the mysterious enemy drawn by Li Chunfeng, the Shenmu Star is the last place to be attacked, and the death time of the life form is also the shortest, so the research value here is the highest.

But it is impossible to judge which direction the Divine Eye Empire fled from the Vega Galaxy.

It was at this time that Li Chunfeng received a message report from Intelligence No. 1 about Heyin, and it became clear that the Divine Eye Empire had fled from here to the direction of Fox, and the mysterious enemy should have been chasing after the destruction of the Divine Eye Star.

This is the end of Heyin's information, in fact, this information was collected by One Intelligence from multiple storage devices and sorted out.

Li Chunfeng immediately called up the star map, and after careful analysis, this mysterious enemy was obviously alarmed by Heyin's exploration fleet, so it chased all the way from the α galaxy of Southern Fish and swept through the entire Divine Eye Empire.

However, along the way, it seems that its purpose is to wipe out the living planet, otherwise with its space technology, Heyin will definitely not be able to escape.

So, is it that the Aquila Ursa civilization planet was missed because it was not detected? Does that mean that it has a certain range of detection of life information? Aquila only has the Cowherd galaxy in this range, so it has suffered a catastrophe.

It seems that Heyin's father, Heying, and the high-ranking officials of the Divine Eye Empire know something about this enemy, otherwise it would be impossible for them to flee the country as soon as they heard Heyin's report.

Sure enough, it is an old third-level civilization, and it still has some taboos in the universe, but No. 1 combed through all the storage devices and did not find this information.

So what level of civilization is the ruins of the high civilization of the Fox Constellation that they fled to, and what kind of place did they leave behind, so that the Divine Eyes are confident that they can escape the pursuit of the mysterious enemy?

Regardless of the Divine Eye, now that he already knows the origin of the mysterious enemy and the specific location of its location, he no longer has to worry about the spatial jump to the direction where it is, and it is time for the Anemo Empire to evacuate immediately.

Li Chunfeng immediately gave the order for the space jump of the whole fleet, and after informing the earth of the specific location of the mysterious enemy for the last time through the virtual world, he broke off all contact between the virtual world and the earth.

At this time, there was basically no one on the earth, and only the fleet of country R was waiting for the direction of the Aeolian Empire to choose, but after Li Chunfeng finished the report, he cut off the connection with the virtual world, and the wishful thinking of Shiro Ohara, the prime minister of the R country, to know the whereabouts of the Aeolian Empire failed.

Fortunately, knowing the specific location of the mysterious enemy, he immediately hurriedly chose the direction of the constellation Sagittarius to open the star gate and quickly escaped.

The three-star system of Nanhe, the space jump of the Aeolian Empire's fleet is about to enter the countdown.

At this moment, the constellation Lyra is in the direction of the constellation Fox, and the warning system placed here sounds.

Li Chunfeng quickly checked the video of the condition of the animal in the satellite sent back by the early warning satellite, and the video showed that the animal died instantly, and the state was the same as that of the animal killed by the death ray before.

Li Chunfeng immediately controlled the warship that was still detecting the magnetic field in the Vega system of Lyra to evacuate.

The two city-class ships almost immediately activated the space jump, but before they could do so, they were hit by a death ray.

At the same time, a message was transmitted directly to the communication receiving devices of the warship and the communications satellite.

"Hey, there's even a little bug here!"
