Whether it was that preliminary Level 6 Civilization or the fleeing Pegasus Civilization, both were merely interludes in Xiao Yu’s expedition. Xiao Yu continued to advance, forging ahead without wavering.

The Divine Ark Civilization had already returned to calm. Once again, Xiao Yu set his attention on construction, on the journey, and on the development of technology. The clash with that preliminary Level 6 Civilization cost Xiao Yu ten million spaceships, and even more spaceships suffered varying degrees of damage. The damaged ships needed repair, the lost ships needed replenishment, and within the small universe the large-scale construction tasks had never ceased.

Even so, Xiao Yu did not come away empty-handed from this war. Obtaining the structural principles of the Loya Round Cup was one gain. Another gain was obtained through analyzing the spaceships of that preliminary Level 6 Civilization.

This gain once again made Xiao Yu certain of his idea that a single civilization could not possibly cover the entire surface of contemporary technology. Because through analyzing those captured spaceships, Xiao Yu once more obtained some unexpected technologies. The direct result these technologies brought was that Xiao Yu’s research into that body fragment of a two-dimensional lifeform made a critical breakthrough.

“We are discussing the feasibility of using two-dimensional technology to construct a new layer of shield.” Xu Junpo reported to Xiao Yu during the scientists’ meeting. “The four-dimensional shield transfers all attacks it suffers away by means of an extra dimension beyond the three-dimensional world. The two-dimensional shield, however, possesses a principle entirely different from that of the four-dimensional shield. When an object enters a two-dimensional world, it too will be two-dimensionalized, and a two-dimensional world has no height. It has only length and width. This means that once an object enters the two-dimensional world, it can only move in the directions of length and width and cannot move in the direction of height. Then can we do this. We cover the outer layer of the spaceship with a layer of two-dimensional space, thereby resisting attacks from outside.”

Xiao Yu understood what Xu Junpo meant. In fact, after obtaining that preliminary Level 6 Civilization’s technology, which caused his own technological system to make yet another step forward, Xiao Yu had already started thinking about this question. The principle of the two-dimensional shield is simple. Whether a light-type weapon attack or a solid-type weapon attack, it must advance, and this direction of advance can be regarded as motion in the height direction. Yet the two-dimensional world precisely has no height. Then when these attacks enter the two-dimensional world, how will they move.

Very obviously, they will be held within the two-dimensional world of the two-dimensional shield. Their motion in the height direction will be converted into motion in the directions of length and width. And since the two-dimensional shield enshrouds the entire hull of the spaceship, this means that an attack coming from the front will be transported by the two-dimensional shield to the back of the spaceship, and then the two-dimensional shield can also release it.

Because the two-dimensional shield is not a truly literal two-dimensional world, the matter that enters the two-dimensional shield will only temporarily lose the third dimension and will not undergo that sort of violent energy release caused by dimensional fall. After it is released by the two-dimensional shield, it will once again possess the third dimension.

This is the entire defensive principle of the two-dimensional shield. As for the principle, Xiao Yu and this group of scientists already understood it and had proven the feasibility of the two-dimensional shield in theory. What they needed to do now was to realize it by technical means.

And with the body fragment of the two-dimensional lifeform as a physical reference, Xiao Yu believed that a true breakthrough was no longer far off.

Aside from the two-dimensional shield, research on the two-dimensional weapon was also proceeding in intense fashion. Xiao Yu was quite certain that in the Milky Way Galaxy only he possessed two-dimensional technology. If he could develop a two-dimensional weapon, he would thus have a certain advantage. The destructive principle of a two-dimensional weapon is also very simple. By means of a certain sealed fragment of two-dimensional space that contains a certain amount of energy as the primer, then by means of a trigger device to trigger it at a specific location, under the provision of energy that two-dimensional fragment will have sufficient ability to two-dimensionalize a certain range of three-dimensional space. And since space is two-dimensionalized, the matter within the space naturally cannot escape the fate of being two-dimensionalized. Whether spaceships or stellar bodies, none can escape being two-dimensionalized.

The three-dimensional main universe possesses a certain self-healing property, so the spatial two-dimensionalization caused by a two-dimensional fragment will not spread without limit. After it has exhausted the energy it carries, the process of spatial two-dimensionalization will stop, and then, under the erosion of the self-healing effect of the three-dimensional main universe, it will gradually shrink the scope of its existence and finally disappear without a trace from the main universe.

Different from the two-dimensional shield, the two-dimensionalization caused by a two-dimensional weapon is permanent and irreversible. Any solid matter that has been two-dimensionalized will, in the instant of dimensional fall, convert that one extra dimension it possessed into energy and release it violently, and in the end, as the two-dimensional space continuously recedes, it will completely vanish from the three-dimensional main universe without leaving the least residue.

Of course, this is only the situation in theory. In the actual process of operation, situations may also appear in which, because the energy in some places is too abundant and space is too solid, matter cannot be two-dimensionalized or pseudo two-dimensionalization occurs. For example, a low-power two-dimensional weapon obviously cannot transform a planet into a two-dimensional existence. For another example, from his Specter companion, Xiao Yu knew that the Sweepers Civilization’s Neutron War Star had experienced being two-dimensionalized and then restored to a three-dimensional structure.

But no matter what, a two-dimensional weapon is ultimately a powerful weapon and worth Xiao Yu’s devoted research.

There were still roughly one thousand five hundred years to reach the Galactic Center. During this period, Xiao Yu launched a large-scale research campaign on this subject. The Space Academy of Science and the Institute of Physics once again received Xiao Yu’s emphasis. Under Xiao Yu’s leadership, the team of scientists with Xu Junpo, Luka Three, and Luka Five at the forefront once again launched an assault operation.

Countless scientists toiled day and night. Countless information was exchanged. This state of affairs lasted for more than two hundred years. Finally, when Xiao Yu had already replenished supplies three times and set out on the journey for the fourth time, the research on the two-dimensional weapon experienced a critical breakthrough. Xiao Yu personally witnessed this event in the laboratory.

It was a transparent glass box. Inside this box was an extremely high-purity vacuum. Aside from a speck of dust with a diameter of only one millimeter, there was basically no other matter present. In such a situation, a two-dimensional fragment to which a certain amount of energy had been injected, under the sealing of the encapsulation device, entered this box.

Because an antigravity device had been employed, there was no gravity in this box. That speck of dust simply hovered quietly in the box, awaiting its unknown fate. And because it had been given an initial acceleration, that two-dimensional fragment was slowly moving forward at a constant speed.

When the distance between the two shortened to less than one decimeter, Xiao Yu issued the order.

“Two-dimensional weapon, activate. All scientists pay attention to every kind of data during the experiment.”

With the issuance of Xiao Yu’s order, a series of indescribable reactions occurred within this thing that looked like an iron sheet. The two-dimensional space fragment sealed within this sheet of iron seemed to have taken a great tonic and suddenly began to expand. The first to be swallowed by it were those iron sheets that wrapped it. They were rapidly two-dimensionalized. In this process, Xiao Yu detected a very obvious energy release reaction. The two-dimensional space continued to expand and finally swallowed that preset speck of dust.

This patch of two-dimensional space ultimately expanded to a diameter of about one meter before finally stopping.

With this experiment concluded, Xiao Yu and the scientists immediately began the subsequent work of data analysis. After analyzing all the data, Xiao Yu announced the result. “This experiment was a success. The two-dimensional fragment we had prepared and sealed in advance, under our control, successfully two-dimensionalized the predetermined target. But this experiment still exposed some problems, namely that the power is too low to expand the kill radius on a large scale and that effective pinpoint strikes cannot be implemented. These two problems mean that the two-dimensional weapon still cannot be applied in actual combat. Next we will continue to research these two problems.”

The two-dimensional weapon is the basis of the two-dimensional shield, because the two-dimensional weapon can be regarded as uncontrolled two-dimensionalization, while the two-dimensional shield can be regarded as controlled two-dimensionalization. This is because the two-dimensional shield still needs subsequently to release the three-dimensional objects or light it has absorbed. If it does not release them, the violent energy released by the dimensional fall of the three-dimensional entities may instead produce other adverse impacts on the spaceship’s shield. The relationship between these two is somewhat analogous to the relationship between a hydrogen bomb and controlled nuclear fusion. And there is no doubt that the hydrogen bomb is the basis of controlled nuclear fusion. Likewise, the two-dimensional weapon is also the basis of the two-dimensional shield.

The two-dimensional weapon had already shown its first rudiments. It could be believed that the development of a two-dimensional weapon that could truly participate in actual combat was not far off, and the research and development of the two-dimensional shield now had hope as well.

Time continued to pass slowly. After another one hundred years, the unidirectional control technology for the linking channel between the main and small universes, based on the Loya Round Cup technology, was finally developed and entered into practical application. From this moment on, Xiao Yu would no longer need to rely on the instrument at the main universe’s end. He needed only the instrument at the small universe’s end to conveniently control the opening and closing of the channel.

This meant that the security of Xiao Yu’s small universe had risen by another level.

Amid slow development, another three hundred years gradually passed.
