It is many times more difficult to find a primordial black hole in the inter-river space than it is to find the primordial black hole in the inner space of the river system. Because Xiao Yu is mainly looking for optics and the influence of the primordial black hole on the surrounding matter, such as stars and other stars. In the inner space of the river system, if a star has an abnormal orbit, Xiao Yu will focus on observing it, and if the light of a star is deflected or a star is abnormally releasing a large number of high-energy rays, it is even better, which basically proves that there is an extreme star there.

In contrast, space-level detection methods can only be regarded as an auxiliary means in the process of finding the primordial black hole.

So...... What kind of means should be used to find the primordial black hole in the interriver space?

There is nothing there. The volume and mass of primordial black holes are generally very small, most of them are only on the order of less than a kilometer. They are also not massive enough for them to have any observable effect on any distant star. Optical observations to find the primordial black hole in intergalactic space? This is even worse. Because there is no light source there.

Compared with the inter-river space, which is often calculated in millions of light-years, the large volume is only a kilometer, and the small one is only a few millimeters, and the primordial black hole of a few centimeters is too tiny. Searching for these little spots in the inter-river space is like looking for a speck of dust that has fallen here by chance in a dark hall. No, it's a million times harder.

There is a more important point, that is, Xiao Yu does not know whether there is a primordial black hole in a certain inter-river space. Perhaps, Xiao Yu has spent a huge amount of resources. They took up valuable observation and search time for their own seed networks, but ended up finding nothing. Compared with the internal space of the river system, the primordial black hole is searched in the intersystem space. It's not a good deal.

But there was no way. The primordial black hole inside the river system is easy to find, but the primordial black hole inside the river system is too susceptible to pollution. In order to get clear and complete information about the rules of the mysteries. Xiao Yu can only do this.

"The only way now is to use the seed network to launch a dragnet search in this dark sea. Most of the primordial black holes are small, which makes their gravitational fluctuations undetectable even if they are a little farther away, and they can only be found by pulling a net to investigate. Xiao Yu thought silently.

With Xiao Yu's order, in this tens of millions of light-years inter-river dark space, countless particles began to be arranged according to a certain geometric law, and then began to move rapidly.

Tiny primordial black holes. It's like gems scattered randomly in this boundless dark space. If you find them, Xiao Yu will be able to obtain endless wealth, and if you can't find them, Xiao Yu will lose all your money.

Xiao Yu has comprehensively adjusted his search strategy, from the strategy of mainly searching for the internal space of the river system to the strategy of mainly searching for the inter-river space. And at this time, Xiao Yu once again noticed some unusual movements of the Stellar Group.

Xiao Yu had a little warning in his heart. As usual, this time the stellar anomaly is still on a reasonable basis. But Xiao Yu knows that it is reasonable. It doesn't mean normal. Xiao Yu still vividly remembers the scene of the duel with the dark star civilization in the Flying Kite Galaxy, at that time, through the logic weapon, through this seemingly premeditated stellar anomaly. The Dark Star Civilization didn't know how much suffering it had caused to Xiao Yu. At this moment, this kind of stellar movement has reappeared, which makes Xiao Yu unvigilant.

This time, the range of stellar movements has been much larger. It is not confined to one or a few river systems. Xiao Yu observed that in all the river systems covered by his seed network, this unnoticeable stellar anomaly occurred. If it weren't for Xiao Yu's infinite computing power. Xiao Yu had no way to separate this stellar anomaly from the normal stellar movement.

"What's going on?" Xiao Yu muttered to himself, "I have reason to believe." Outside of my seed network, this stellar anomaly is also happening in the rest of the river system. It may even be a phenomenon that covers the whole universe or most of the universe...... But what exactly was their plan? What is this for? ”

This situation was so familiar that Xiao Yu couldn't help but think of the rebel camp with logical weapons. And, if these stellar anomalies are really the work of the rebels, what are they for? Is it for yourself?

But at this moment, Xiao Yu has no way to analyze these things thoroughly, because the intelligence sources are insufficient. Xiao Yu had no choice but to suppress his suspicions for the time being, and continued his plan to search for the primordial black hole.

In this long search, a certain point in the dark space of the river system caught Xiao Yu's attention. In terms of distance, this point is between four million and seven million light-years away from each of the three river systems in its vicinity. It was nothing, no stars, no planets, no asteroids, not even interstellar dust. In such cases, some of the gravitational fluctuations that occur there are extremely unusual. Xiao Yu's mood immediately became excited. Xiao Yu had a hunch that perhaps, the first harvest since he launched his search in the inter-river space was now.

Millions of particles obeyed Xiao Yu's command and immediately rushed towards that place. In order to avoid too much information from polluting the possible primordial black hole, Xiao Yu did not use visible light or other wavelength rays and any ray-level detection. Xiao Yu only carried out accurate measurements of gravitational fluctuations and spatial fluctuations around that point.

The measurements told Xiao Yu that there was indeed a black hole there. The black hole is very small, with a mass of about 10 trillion tons. This mass is roughly equivalent to a large mountain range on Earth. This result once again made Xiao Yu excited. Such a tiny black hole, if not created by the power of science and technology, can only be a primordial black hole. After the rules appear and stabilize in the universe, such black holes cannot be born through natural evolution.

The particles immediately began to assemble, combining different instruments and even a stargate that could be used for rapid teleportation over long distances. Under such circumstances, about eight years later, this tiny black hole appeared on Xiao Yu's palm.

Xiao Yu looked at the small black hole slowly rotating in his palm with some eager eyes, and secretly sighed in his heart: "What a beautiful little guy...... Well, I don't know what mysteries are hidden in your body? ”

This black hole is so small that it almost belongs to the category of the microscopic world, and it is impossible to see it with the naked eye of humans. But all this is not an obstacle for Xiao Yu. This is the first primordial black hole that Xiao Yu searched in the inter-river space, a primordial black hole that has not been polluted too much. The rule information contained in it is likely to become an opportunity for Xiao Yu to grasp time.

Xiao Yu slowly raised the speed of light in the environment in which the tiny black hole was located. As a result, it became even more insignificant, and in the process, some hidden information was slowly exposed.

From this information, Xiao Yu perceived a clear and complete information that was completely different from the primordial black holes he had collected in the past. In just a moment, Xiao Yu was sure that this information was what he wanted.

This miniature black hole existed in the palm of Xiao Yu's hand for less than thirty seconds before it was finally destroyed. But in just these thirty seconds, the harvest has already exceeded the sum of more than 1,000 primordial black holes that he had collected before. This is the difference between a less polluted primordial black hole and a more polluted primordial black hole.

A larger data stream began to be calculated in Xiao Yu's mind, and the laboratory in the Science spacecraft once again began to be busy with experiments because of the support of new data. This black hole alone has brought a great impetus to Xiao Yu's research work. Many problems that Xiao Yu struggled to solve before were overcome in one fell swoop with the support of new data.

But that's not enough. Although the effect of this miniature primordial black hole is large, it is not enough to support Xiao Yu to completely overcome the problems he faces. Xiao Yu still needs to continue to collect the primordial black hole to get more data support.

Time is still slowly passing, and Xiao Yu has spent thousands of years searching for primordial black holes in the inter-river space within tens of millions of light years. The final result was that Xiao Yu had harvested a total of about 190 primordial black holes, of which the smallest one had almost reached the lower limit of the mass that the primordial black hole could exist in now, and the largest one was only the mass of the moon. Just for the sake of these one hundred and ninety small things whose largest ones are only a few millimeters in diameter and the smallest ones that are smaller than an atom, Xiao Yu used his infinite computing power, his huge seed network to mobilize all his strength, and used his super scientific and technological strength that was proficient in almost all types of eighth-level civilizations as the foundation, and it took thousands of years. There is no way, the universe is too big, and these things are too small.

Although these 190 primordial black holes are still not enough to support Xiao Yu to overcome all the problems, they are enough to make Xiao Yu's research produce a qualitative change. Xiao Yu had a hunch that the time was ripe for the first time experiment. (To be continued......)
