This time to attack the Great Unification Theory, Li Chunfeng conducted the longest scientific research since his rebirth in the real world.

In fact, in order to save time as much as possible, Li Chunfeng put a lot of derivation and calculations in the virtual world, making full use of the 15:1 time difference between the virtual world and the real world.

Only those parts that need to be tested in reality are put in reality, and the virtual world and the real world take far more than 5 years combined.

Sure enough, the path of impacting a fourth-level civilization from a third-level civilization, even if there are some opportunities and luck, still requires a lot of manpower, material resources, creativity, and essential time.

After five years, some of the supplies trapped in the ship have become less and less, and now they can finally be rescued.

With the successful breakthrough of the Great Unification Theory, the mystery of the sluggish void has been solved to a considerable extent, but Li Chunfeng still has no clue why this void produces such a powerful gravitational source.

However, some phenomena caused by this gravitational source gave Li Chunfeng an opportunity and successfully mastered the theory of grand unification.

In this void, due to some unknowable spatial factors, a certain powerful gravitational source has been generated, and all spaceships that enter this void will have propulsion converted into electromagnetic force and gravitational force, thus losing power and falling here.

Now that he has mastered the theory of great unification, Li Chunfeng can completely create a shielding device to shield this gravitational source.

This allows the ship to regain momentum and move through the area.

After five years of development, the Aeolian Empire is now more powerful, with a large number of warships flooding the solar system, the Nanhe Sanxing system, the Proxima Centauri triad galaxy, and even some distant galaxies.

Its manufacturing capacity is even more impressive, so that 10,000 sets of shielding equipment were completed in just one day.

Later, he used the space jump to send the device to Proxima Centauri, and at this time, the titanium star in Proxima Centauri has become the most important resource star in the Aeolian Empire.

It can be said that a large number of warships can be built in five years, and thanks to the fact that ilmenite here is very easy to mine, this planet is simply a titanite planet.

If it weren't for the fact that it was too big, Li Chunfeng would even have a desire to build it directly into a space battle star.

For a larger warship, Li Chunfeng was still very eager in his heart, it turned out that in the third-level civilization stage, the warship manufacturing technology had encountered a bottleneck.

Now that he has finally stepped into the fourth-level civilization, perhaps with the emergence of new technologies, his warship manufacturing technology will be further improved, and he will be able to build larger warships at that time.

Only a huge warship can give Li Chunfeng more security, and now that he has broken through the theory of great unification, some new technologies will emerge in an endless stream, and after a while, a larger flagship will be built.

Due to the explosion in the number of warships of the Fengshen Empire in the past five years, Li Chunfeng has divided the fleet into 20 large fleets, with a minimum number of 1,500 ships in each fleet.

That is, after five years of development, the Aeolus fleet already has more than 30,000 warships.

It's just that the mining fleet sent in the past few years, except for the direction of the Divine Eye Empire, has turned over hundreds of galaxies in other directions, and there are only three galaxies where energy has been discovered, and the reserves are far lower than that of the solar system.

As a result, in the case of energy shortage, many warships are no longer able to use space jump devices at will. In addition, in the past few years, the research on the "electric flash" device of the Divine Eye Empire has not made much progress, mainly because the gamma ray explosion has completely destroyed many electronic devices in the device.

If it is only imitated, it means that after use, the battleship will run out of energy, but this "electric flash" device does not let the battleship run far away, so won't the battleship become a lamb to the slaughter?

Therefore, it is useless to imitate such a device.

As for the stargate device of the Heavenly Organization, there has been a lot of progress so far, but it has not yet fully understood the spatial theory and the mechanism for the establishment of spatial coordinates.

Li Chunfeng used the Iceman's cold nuclear fusion tower to provide energy for the opening of the stargate, and found that the stargate was larger than that opened by the nuclear fission reactor of the Heaven Organization, and the distance could be farther after crossing the past.

It appears that similar to the space transition device, this type of stargate also has the power of the energy supply to determine its traversal distance.

However, there are still a lot of restrictions on this kind of stargate, that is, the location where the stargate is opened must be near a planet, and it obviously needs to rely on a part of the planet's gravity.

Originally, this restriction was not a problem, but every time the stargate was opened, it could not be positioned in the same position again, that is to say, when the same set of stargate devices was opened again, the opened stargate led to the other side of the space, which was not the same place.

This restriction is too great, which means that the stargate can only be used once, and if it is used again, it will be a new unknown airspace.

There is no way, at present, Li Chunfeng can only use the space transition device supported by energy to carry out the fixed-point space jump.

It was these factors that caused Li Chunfeng to only wait for the natural wormhole to return to calm before he could go to the Divine Eye Empire. Otherwise, Li Chunfeng was afraid that he would have already arranged for the fleet to attack the Shenmu Empire on a large scale.

However, at the two wormhole entrances in the direction of Cygnus and Aquila, Li Chunfeng has completed the construction of the space fortress and is equipped with a powerful garrison fleet.

Although the energy is tight, saving people is like fighting fire, not to mention that the ten life-level spaceships have been trapped for five years, and the spirit of the personnel on the ship is almost on the verge of collapse.

Therefore, the warship transporting the gravitational field shielding equipment still came to the outside of Proxima Centauri through space jumps.

The current fleet guarding the Kuiper Belt in the Proxima Centauri system also serves as a rescue fleet, and has rotated several batches in the past five years, and now it is the turn of the 18th Fleet of the Empire to be stationed here.

The entire fleet, with the "Tang Xuanzong" as the flagship, has 1,600 warships of various types, stationed in the space home port of the Kuiper belt of the Proxima Centauri.

Its fleet commander is Lin Tao, and the chief of staff is Su Chenggong.

After receiving instructions from the head of state, Li Chunfeng, they saw the warship transporting gravitational field shielding equipment appear, and the two quickly arranged for all the warships in the fleet to quickly install this set of equipment.

Lin Tao was very happy to know that this time he could finally successfully rescue that fleet. You must know that five years ago, as a member of the General's Observation Group, he came with the first rescue fleet.

Unexpectedly, this matter actually spanned five years, and the power of the Wind God Empire now extends to dozens of galaxies.

Dongfang was also very worried that his elite fleet was trapped in the void, and in the past five years, he has also sent his own experts to come here to study the void together by taking the battleship of the Aeolus Empire.

At this time, there was a group of experts from the East in the space home port, who were very curious and wanted to know more about the situation when they heard that the Aeolus Empire had studied the mystery of the Stagnant Void and developed a device to solve the problem.

Lin Tao knew that they definitely wanted to follow, so he didn't stop them, and brought them all, just so that they could see the power of the empire's technology.

After five years, the earth's "nuclear winter" has not passed, although countries have come up with many ways to clean up the atmosphere, but the effect is not very good.

Moreover, the earth's ecological sphere is basically destroyed, and it is almost impossible to restore the entire ecological chain without decades or even hundreds of years.

Therefore, while conducting scientific research, Li Chunfeng sent two exploration fleets to find a living planet that could be habited, but they all returned in vain.

As for the "Huo Quai" fleet, which was the first to be dispatched, it lost contact with it after the last jump to the sail seat, and has not been heard from since.

This is also Li Chunfeng's determination not to give up until he breaks through the theory of great unification.

Only by mastering this grand unified theory can we grasp the mystery of energy conversion, so that we can carry out ultra-long-distance interstellar voyages without the need for energy.

Now that I have been immersed in research for five years, I have finally gained something, and I believe that with the continuous enrichment and improvement of the Great Unification Theory in the future, and on this basis, the development of new science and technology, and the introduction of new applications, the Fengshen Empire will gradually become a mature fourth-level civilization.

Not to mention how Li Chunfeng thinks about the next development of the Fengshen Empire.

At this time, the 18th Fleet dispatched a full 500 warships, a huge group of warships, igniting a dazzling tail flame, and the nuclear fusion engine brought powerful power.

All 500 warships were equipped with new gravitational field shielding equipment, which had also been turned on early at this time, and Lin Tao originally planned to sail directly to the vicinity of the rescued life-class spaceship.

However, Chief of Staff Su Chenggong was a cautious man, and he suggested sending a vanguard fleet of 100 warships to advance into the sluggish void in a large horizontal formation.

If all goes well, and nothing out of the ordinary, the entire fleet will then enter the Void of Sluggishness.

"Success, you don't believe in the Führer!" Lin Tao said jokingly.

Su Chenggong shook his head and said: "It's not that I don't believe in the Führer, but anything can happen in the universe, and it will never be wrong to sail the ship carefully." ”

Lin Tao nodded helplessly and said, "Okay, just do as you say." Anyway, listening to your words, you haven't suffered a loss. ”

Lin Tao and Su Chenggong have been leading the 18th Fleet for three years, and in the annual offensive and defensive exercises of the fleet, many of Su Chenggong's suggestions have made the fleet suffer less, so that the 18th Fleet's achievements can always rank in the top five.

This time, it was the turn of the 18th Fleet to take on the task of rescuing the fleet, and it was also the first time in many years that it had received a mission from the Führer himself.

Lin Tao also attaches great importance to it in his heart, knowing that it is always right to be careful.

The fleet quickly divided into two echelons, and the forward 100 warships moved forward quickly, and six days later, the vanguard fleet rushed into the sluggish void.

This time, under the effect of the gravitational field shielding equipment, the battleship was not affected in any way, the dazzling tail flame was still gorgeous, and the battleship headed towards the trapped fleet at high speed.

"Everything is fine with the vanguard fleet!" Brain quickly reported the situation.

"Well, the whole fleet is speeding up! Immediately send a telegram to the trapped fleet, they will soon be saved, and we will arrive at the place where the fleet is trapped in 10 days, and then we will send a transport ship to send over the new equipment and install it on them, and then we will be free. ”

Lin Tao quickly gave instructions to Zhi Brain.

"Lin Tao, you'd better turn on the sine wave detection equipment, have a good probe of the sine wave here, and submit the detected data to the head of state at that time, maybe it will be a great achievement." Su Chenggong suddenly suggested.

Lin Tao was stunned, couldn't help laughing, and said, "Sure enough, it is worthy of Su Chenggong, this brain is turning so fast!" ”

So Lin Tao quickly ordered Zhi Brain to turn on the sine wave detection equipment.

The Führer had been studying this place for five years, and now that he had developed such a device, it was clear that there was a big secret here, and the situation of the sine wave should be part of the secret.

This data for the Führer should be considered a good gift.

Ten days later, the fleet finally arrived near the trapped fleet, and a transport ship equipped with gravitational field shielding equipment flew out of the flagship "Tang Xuanzong" and flew straight into the dock of the life-class spaceship.

When the equipment was installed by the maintenance robot, the ten life-class ships restarted their engines, and the surging power that had been lost for a long time suddenly made the ships start to move.

"It worked! We are finally saved! ”

"Oh my God, it's been five years!"

"The hard days are finally over!"

"The aliens have been beaten away, can we go back too?"

"It's not easy to go back, haven't you heard that the earth is now a 'nuclear winter'? It's the same place as us, it's a closed place, and there are no more green mountains and green waters. ”
