Now Xiao Yu has a feeling of standing on the shoulders of giants. Because Xiao Yu knew that he was not fighting alone. It's not just one person, or the Shenzhou civilization, a civilization that is fighting against the Sweeper civilization.

The Taihao Alliance directly participated in the war and helped Xiao Yu fight against the Sweeper civilization. The long-dead semi-four-dimensional Taihao left Xiao Yu with four maintenance shields to fight against the soul attacks of the Sweeper Civilization, and the Guardian Civilization handed over the high-dimensional technology materials to Xiao Yu for Xiao Yu to use to fight against the high-dimensional attacks of the Sweeper Civilization. The three major alien beast civilizations have all been killed in battle, and all their body materials have been used by Xiao Yu to build warships with more outstanding performance, and the dead MSI civilization has left its own corpse, so that Xiao Yu can fight against the neutron battle star. In addition, there are space creatures that left Xiao Yu with a two-dimensional maintenance shield and two-dimensional weapons.

Together with Xiao Yu and the associated ghost clan, there are a total of eleven powerful existences. Eleven powerful beings gathered here in Xiao Yu, with Xiao Yu as the center, to fight together against the Sweeper civilization.

This is definitely the strongest group that can be organized within the galaxy. If it still can't defeat the Sweeper civilization with such strength, then, in the galaxy, the Sweeper civilization is truly invincible.

Xiao Yu felt that his strength had reached a peak. But Xiao Yu still doesn't know what the arrangement made by Luka No. 2 and Xu Junpo does.

"Perhaps, these arrangements are really as they say, just a last resort, and they are used to get me to escape. However, now that I have a way to fight all the attacks of the Sweeper civilization, how could I fail? Xiao Yu thought silently, "There are eleven powerful existences...... Coupled with the microscopic civilizations that once handed me the seventh-level civilization materials, this is twelve. ”

From the moment he received the Guardian Civilization Science and Technology Data, Xiao Yu had already begun to analyze these materials. Xiao Yu discovered that the Guardian Civilization had indeed carried out fruitful research on the high-dimensional space. Even so, they have limited the space energy formula to a certain range.

Just like the mass-energy formula, this formula unifies mass and energy together, so it opened the door to nuclear energy and pushed mankind into the second-level civilization, and now, between the sixth and seventh level civilizations, there is also such a formula.

Empty energy formula. A formula for the mutual transformation of space and energy. This formula will tell Xiao Yu how much energy a unit of space can be converted into, and how much energy a unit can be converted. And how much space can be converted into it. As long as you master this formula, you will truly open the door to a seventh-level civilization.

Of course, this is only to open the door, just as when mankind first mastered the mass-energy formula, it did not immediately enter the era of nuclear energy. It takes a process.

However, it can be said that the mass-energy formula has been mastered. Entering the age of nuclear energy is a sure thing. Mastering the formula of empty energy, entering the seventh-level civilization is a sure thing, and it is only a matter of time.

"It seems that the Guardian Civilization is also plagued by the seventh-level barrier, so it can't fully grasp the void energy formula, but only limits this formula to a certain range. That's quite enough of an achievement. Not. That seventh-level microscopic civilization only told me some scientific and technological information of the seventh-level civilization, some applied technology, but no basic technology, but. Combining the research data of the Guardian civilization with the research data of the seventh-level micro-civilization may allow me to make some other discoveries. ”

Xiao Yu quickly summoned relevant scientists and launched research in this area.

Xiao Yu has already determined the direction of this research. Since space dimensionality reduction will release energy, it is very simple to draw the following inference: injecting energy into space can make space ascend. What Xiao Yu is doing now is to truly create a four-dimensional space through his own means. After understanding the various properties of the four-dimensional space, Xiao Yu can find a way to resist the four-dimensional attack of the neutron battle star.

However, Xiao Yu's research soon encountered difficulties, and the reason for the difficulties was still because of the seventh-level barrier. Xiao Yu had already determined that injecting energy could make the space ascend, but because he had not mastered the formula of empty energy, he could not determine the amount of energy. If that's all it takes, it doesn't matter, in many repeated experiments, Xiao Yu can always find the right quantity, and even use this to reverse the empty energy formula, but unfortunately, this method is not feasible.

Because of the existence of the seventh-level barrier, Xiao Yu still observed the uncertainty in this experiment. All the experimental data that Xiao Yu observed had some random nature and were not reproducible at all, so the data had no value.

"Until the seventh-level barrier is breached, such research does not seem to make sense." After countless failures, Xiao Yu was sure of this result. As a result, Xiao Yu disbanded the scientists who had organized a special organization to study this technology.

Xiao Yu is certainly not prepared to give up on this research. Because this is the only way to counter the high-dimensional attacks of the Sweeper civilization. Xiao Yu's plan is to increase the success rate with a huge number.

Assuming that the chance of successfully creating a four-dimensional space in an experiment is only one in a billion, then all Xiao Yu has to do now is to conduct a billion or more such experiments. One billion experiments, even if the success rate is only one in a billion, according to the probability, there should always be one success, right?

So, in the following time, Xiao Yu prepared countless test sites, manipulated these many experimental equipment with his huge computing power, and began the manufacturing experiment of the four-dimensional space together. Xiao Yu no longer expects to master the formula of empty energy at this stage, but as long as he can enjoy some scientific and technological achievements, it is enough.

In these countless experimental sites, failures are staged every day. There have been many times when Xiao Yu has successfully created a four-dimensional space through a large amount of energy infusion, but he has encountered failure in expanding the volume of the four-dimensional space, and that damn instability has continued to attack, constantly blowing up the four-dimensional space created by Xiao Yu.

This is like a large wheat field, Xiao Yu planted a lot of wheat in this wheat field, as long as there is a wheat final fruit, Xiao Yu cultivates these plants diligently, but instability is like a most annoying insect, my sister kills the wheat when the seeds have just germinated, and even before they germinate. Xiao Yu was never able to get a ripe wheat.

Xiao Yu was not discouraged, but kept carrying out these experiments. Time passed slowly in this way, a hundred years passed. There are less than four hundred years left before the arrival of the Sweeper civilization.

Large-scale construction activities have been further refined and are expected to be fully completed fifty years before the arrival of the Sweeper civilization. The war game is going well, and the current war game has fully entered the era of fleets, and every day there are players controlling a large number of fleets to fight in the virtual starry sky. All kinds of tricks and tactics are constantly being staged here. But no matter how the game evolves, it is always Jianqi and Rose who occupy the first and second place.

The two even organized two guilds in the game, making them the two largest on the server. Of course, the two guilds are hostile to each other, and players in the game know that as long as the fleet of the Jianqi Guild and the fleet of the Rose Guild meet, a major war will inevitably break out.

In the midst of endless wars, they are growing rapidly. Even, Xiao Yu was already beginning to think about whether to let Yang Jianqi and Rose, as well as some other outstanding people, go to the field to control the battleship for interstellar warfare in advance.

Time is still slowly passing, and the long-term effort has finally paid off. In the midst of countless failures, Xiao Yu finally succeeded in cultivating a four-dimensional space. It is a four-dimensional superbody, and its length, width, height, and the length of the fourth dimension are all ten kilometers. The mystery of the four-dimensional space was finally shown in front of Xiao Yu for the first time. And in order to create this four-dimensional superbody and let the four-dimensional structure curled up in the macroscopic universe be revealed, Xiao Yu paid the price of at least ten stars.

The existence of this four-dimensional superbody is not stable, and it is slowly losing its fourth dimension under the erosion of the three-dimensional universe. Therefore, Xiao Yu's research must be carried out quickly. Xiao Yu specially developed a large number of spaceships and instruments, and activated them into the four-dimensional superbody to study how to defend and attack the spacecraft in the four-dimensional environment.

"The universe is three-dimensional, and the four-dimensional structure of the universe is all curled up into the microcosm, and they refuse to expose their true colors. In the three-dimensional universe, it is impossible to sail in four dimensions. Then the only way is to temporarily open up a four-dimensional channel, and use this four-dimensional channel to achieve the purpose of a four-dimensional attack. I believe that the four-dimensional jump of the Guardian civilization and the high-dimensional attack of the Sweeper civilization are based on this principle, but the development direction is a little different. With this principle as a support, it is easy to find a solution......"

Xiao Yu finally found this solution. Xiao Yu's countermeasures are divided into two ways, the first is to construct a real four-dimensional enclosed space to wrap his spaceship and block the way to enter the spaceship from the four-dimensional direction. It's like drawing a circle in a two-dimensional world, or building a closed iron ball in a three-dimensional world. However, this method also has a flaw, that is, the closure can be forcibly opened. In the face of the Neutron Battlestar's formidable combat power, this method is not very reliable.

So, Xiao Yu found a second way. (To be continued......)

PS: The second more later...... Whew, finally got the card, the torture is finally over, it's time to celebrate, the second will be a 5,000-word chapter
