This time, 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 large number of derivations 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 require real-life experiments are put into reality. The virtual world and the real world combined have taken far more than 5 years.

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

In five years, some of the materials trapped in the spacecraft have become less and less, and now we can finally rescue them.

With the successful breakthrough of the Great Unification Theory, the mystery of stagnating voids was also cracked to a considerable extent, but Li Chunfeng still had no idea why this void produced such a powerful source of gravity.

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

In this void, due to some unknown spatial factor, a powerful source of gravity is generated. Any spacecraft entering this void will transform propulsion into electromagnetic force and gravity, thus losing power and trapping here.

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

In this way, the spacecraft can regain power and pass through this area smoothly.

After five years of development, the Wind God Empire is now even more powerful, with a large number of warships flooding the solar system, the Nanhe Three Galaxy, the Proxima Triad Galaxy, and even some distant galaxies.

Its manufacturing capability is even more amazing, so the spacecraft needs 10,000 sets of shielding equipment in just one day.

Then, the equipment was sent to the Proxima Galaxy using space transition. At this time, the titanium star in the Proxima Galaxy had become the most important resource star in the Wind God Empire.

It can be said that the number of warships can be built in five years, which is also due to the fact that the ilmenite here is very easy to mine. This planet is simply a ilmenite planet.

If it weren't for its size, Li Chunfeng even had the desire to directly turn it into a space war star.

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

Now that we have finally entered the fourth-level civilization, perhaps with the emergence of new technologies, our own warship manufacturing technology will be further improved, and we can build larger warships by then.

Only huge warships can give Li Chunfeng a greater sense of security. Now that he has broken through the theory of great unification, some new technologies will emerge one after another. After a while, he will build a larger flagship.

Since the number of warships in the Wind God Empire has exploded in the past five years, Li Chunfeng has divided the fleet into 20 large fleets, with a minimum number of 1,500 ships per fleet.

In other words, after five years of development, the Fengshen Fleet has already owned more than 30,000 warships.

However, the mining fleets sent in recent years have been circulating hundreds of galaxies in other directions except for the direction of the Divine Eye Empire. It was found that only three galaxies with energy were found, and the storage capacity was far lower than that of the solar system.

As a result, when energy is tight, many warships can no longer use space transition devices at will. In addition, in recent years, research on the "lightning" devices of the Shenmu Empire has not made much progress, mainly because gamma ray explosions have completely destroyed many electronic devices in the device.

If it is just imitation, it means that after use, the warship's energy will be exhausted. But this "lightning" device prevents the warship from running far away. Wouldn't the warship become a lamb to be slaughtered?

Therefore, imitating this device is useless.

As for the star gate device organized by Paradise, there has been considerable progress at present, but the space theory and the mechanism for setting up space coordinates have not been fully understood.

Li Chunfeng used the Iceman's cold nuclear fusion tower to provide energy for the star gate to open, and found that the star gate opened by the nuclear fission reactor of Paradise organization was larger, and after traveling through, the distance could be further.

It seems that similar to a space transition device, this star gate also has the power supplied by energy to determine its crossing distance.

However, there are still many restrictions on this kind of star gate at present, that is, the position where the star gate is opened must be near a planet. Obviously, it needs to rely on some planetary gravity.

Originally, this restriction was not a problem. It was just that after each star gate was opened, it was impossible to locate the same position again. That is to say, the same star gate device was opened again. The star gate opened and the other side of the space leading to are not the same.

This limitation is too great, which means that the star gate can only be used once, and if it is used again, it will be a new unknown space.

There is no way. At present, Li Chunfeng is undergoing a fixed-point space transition, so he can only use a space transition device supported by energy.

It is precisely these factors that led to Li Chunfeng having to wait for the natural wormhole to return to calm before he could go to the Divine Eye Empire. Otherwise, Li Chunfeng would have been afraid that he would have arranged a fleet to attack the Divine Eye Empire.

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. If the wormhole entrance returns to normal and the Divine Eye Empire attacks first, they will be destruction.

Although the energy is tight, saving people is like putting out a fire. What's more, the ten life-class spacecraft have been trapped for five years, and the people on the ship are almost on the verge of collapse.

Therefore, the warships that transport gravitational field shielding equipment still come outside the Proxima galaxy through space transition.

Currently, the fleet guarding the Kuiper belt in the Proxima Galaxy also serves as a rescue fleet. It has rotated multiple batches over the past five years. Now it is the turn of the Empire's 18th Fleet to garrison here.

The entire fleet is based on the "Tang Xuanzong" as its flagship, with 1,600 warships of various types, stationed in the space home port of the Kuiper belt of the Proxima Galaxy.

The commander of its fleet was Lin Tao and the chief of staff was Su Chenggong.

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

Lin Tao was very happy and knew that he could finally successfully rescue the fleet this time. You should know that five years ago, as a member of the General Observation Group, he followed the first rescue fleet.

Unexpectedly, this incident spans five years, and the current power of the Wind God Empire has also extended to dozens of galaxies.

Dongfang was also very worried that his elite fleet was actually trapped in the void. Over the past five years, he sent his own experts to come here to study the void together by riding the warships of the Wind God Empire.

At this time, there were a group of experts from the East in the space home port. When they heard that the Wind God Empire had developed the mystery of stagnant voids and developed equipment to solve the problem, they were all very curious and wanted to learn more about the situation.

Lin Tao knew that they must have wanted to follow him, but he didn't stop him and brought them all, just so that they could see the power of 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 some atmospheric conditions, the effect is not very good.

Moreover, the earth's ecosystem has basically been destroyed and is devastated at this time. It is almost impossible to restore the entire ecological chain without decades or even hundreds of years.

Therefore, while Li Chunfeng was researching, he sent two exploration fleets to find a livable life planet, but they all returned in vain.

As for the first fleet of "Huo Qubing" sent, it lost contact after the last jump to the sail seat and has no news yet.

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

Only by mastering this unified theory can you master the mystery of energy conversion, so that you can also conduct ultra-long-distance interstellar voyages without needing energy.

Now that I have been studying for five years, I have finally gained something. I believe that with the continuous enrichment and improvement of the theory of great unification in the future, and the development of new technologies and the introduction of new applications on this basis, the Fengshen Empire will gradually become a mature fourth-level civilization.

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

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

All 500 warships were equipped with new gravitational field shielding equipment, which was opened early at this time. Lin Tao originally planned to drive directly to the rescued life-class spacecraft.

However, Chief of Staff Su Chenggong was a cautious person. He suggested sending a vanguard fleet of 100 warships to advance into the stagnant void in a large horizontal formation.

If everything goes well and there is no abnormality, the entire fleet will enter the stagnant void.

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

Su Chenggong shook his head and said, "It's not that he doesn't believe in the head of state, but that everything can happen in the universe. Be careful of sailing a thousand-year-old ship, you will never be wrong."

Lin Tao nodded helplessly and said, "Okay, just do what you said. Anyway, I have never suffered any loss after hearing what you guy said."

Lin Tao and Su successfully led the 18th Fleet for three years. In the annual fleet offensive and defensive exercises every year, Su Cheng's suggestions made the fleet suffer less losses, so that the 18th Fleet's results can always rank in the top five.

This time, the 18th Fleet was the turn to undertake the rescue fleet mission, and it was the first time in many years that the head of state had received a task personally issued by the head of state.

Lin Tao also attaches great importance to it, and it is always right to be careful.

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

This time, under the action of the gravitational field shielding equipment, the warship was not affected at all, and the dazzling tail flame was still gorgeous, and the warship sailed towards the trapped fleet at high speed.

"Everything is normal in the forward fleet!" The smart brain quickly reported the situation.

"Well, the whole fleet will accelerate! Immediately generate electricity to the trapped fleet, and they will be saved soon. We will arrive at the trapped place of the fleet in 10 days. At that time, the transport ship will be sent to send new equipment and install it for them, and the trap will be solved."

Lin Tao quickly issued instructions to the smart brain.

"Lin Tao, you'd better turn on the string wave detection equipment and detect the string waves here. By then, submitting the detected data to the head of state may be a great achievement." Su Chenggong suddenly suggested.

Lin Tao was stunned for a moment, couldn't help but smile, and said, "It's true that it's Su Chenggong. His brain is really fast!"

So Lin Tao quickly issued another string wave detection device to the smart brain.

The head of state has been studying here for five years and has now developed this kind of equipment. Obviously, there is a big secret here, and the situation of string waves should be part of the secret.

This data given to the head of state should be considered a good gift.

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

When the equipment was installed by the maintenance robot, the ten life-class spacecraft restarted the engine, and the long-lost surging power immediately made the spacecraft start to move.

"Success! We are finally saved!"

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

"The hard days have finally come to an end!"

"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 'nuclear winter'? Like us, there is also living in a closed place, and there are no more green mountains and clear waters."
