The submarine had just descended a few meters deep when it was completely dark. It was absolutely silent and absolutely dark, with nothing to be seen, nothing to be heard, only a raging undercurrent crashing against the hull.

It is the deepest trench in the ocean, estimated to be more than 20,000 meters deep. After reaching the bottom, the submarine is expected to be subjected to pressure of thousands of atmospheres. However, with the instruments made by Xiao Yu's current material technology, it is not a problem to withstand these pressures at all, and it doesn't matter if it's even bigger.

In the process of slowly diving, Xiao Yu remembered that in the Aquila Nebula, he controlled the spacecraft to collect flowing gold inside the gaseous planet. This expedition is very similar to that one.

Because the planet doesn't have enough moons, the oceans here don't have tides. To be precise, there are tides, but they are caused by the gravitational pull of the main star and the gas planet. Because of the distance, the tide is so faint that it is almost imperceptible.

The absence of tides means that the planet's oceans are calm, and the currents inside the oceans are very weak and scarce. It's easy to see one area rich in potassium and the other rich in magnesium, and there is no efficient exchange of materials between the two areas.

The emergence of life requires a variety of elements as raw materials, and this single material situation is very unfavorable to the emergence of life. However, in some special places, there is still the possibility of life. Xiao Yu did not give up hope because of this.

Xiao Yu manipulated these submarines, collecting surrounding data and measuring the composition of the seawater in detail, while continuing to dive, deeper and deeper.

Xiao Yu is looking for an undersea volcano. The emergence of life requires heat. On the surface of the planet, because the planet's atmosphere and magnetic field have not yet fully evolved, it cannot effectively block harmful rays from stars and the universe for the time being, so although the temperature is sufficient, it is unlikely that life will evolve there. Under such circumstances, the environment near the submarine volcano is undoubtedly very much in line with Xiao Yu's expectations.

The seawater is up to 10,000 meters thick and can provide very close protection for life, and submarine volcanoes can provide life with the necessary heat and various minerals necessary for life.

At present, the depth has increased to 19,000 kilometers. If a person is in this position. He would be crushed in an instant, his bones would be crushed, blood would flow out. However, with the support of Xiao Yu's super material technology, this submarine still did not appear abnormal.

Xiao Yu was paying close attention to the slight changes in the elemental composition of the surrounding seawater. Searchlights with super penetrating power are swaying around.

Finally reached the bottom of the sea. Because of the lack of life, the planet's seabed is different from the seabed above Earth. There is very little silt here, and most of it is fine and soft gravel. Under the glow of a searchlight. It reflects a yellowish glow.

It's deserted, quiet and like you're in space.

"Based on the sounding data, it is speculated that there should be an active volcano over there, about five kilometers...... Go over and take a look. ”

Xiao Yu steered the submarine and slowly approached there.

The temperature of the surrounding sea is getting higher and higher. It is getting higher and higher, until it rises to more than 500 degrees Celsius, and it is still slowly rising.

At a standard atmospheric pressure, the temperature of water can only reach a maximum of 100 degrees. More than 100 degrees it will evaporate its heat by boiling, but the air pressure here is much higher than the standard atmospheric pressure, in which case the water will not boil even if the temperature reaches 1,000 degrees Celsius.

After slowly sailing a distance of several kilometers, Xiao Yu saw an astonishing scene.

Here, there is an undersea volcano, and it is erupting. A large amount of dark red magma is flowing out of its crater and slowly flowing down the surrounding rocks, and in the process of flowing, the heat it carries is given to the seawater, and the hot water rises, and the cold water falls, and in such a convective process, there is a full exchange of materials here.

"This is the ideal breeding ground for simple creatures. If they do exist, there's no better place to be. Xiao Yu thought secretly, opened the submarine valve, let some seawater in as a specimen, and, braving the heat of nearly 1,000 degrees, approached the volcano, and collected some volcanic ash on top of its mountain.

After doing all this work, the submarine continued its journey. It will last three months of seabed operations, after which it will return to the surface, where the specimens will be taken by Xiao Yu and brought back to the laboratory for detailed analysis.

In total, tens of thousands of submarines are working on this work. In addition to these instruments for undersea operations, Xiao Yu also sent a large number of robot troops to explore various caves on the planet.

Like Earth, there are many caves on this planet, some of which are tens of kilometers deep. Caves are the other place where living beings are most likely to be present in addition to the bottom of the sea. Robots and equipment have been sent to the north and south poles of the planet to search for life under the ice cap and in the crevices of the ice......

Under this all-round exploration method, Xiao Yu believes that if there is a creature on this planet, then it will definitely be found by himself.

Finding the native creatures of this planet is Xiao Yu's private matter. The development of science and technology and the improvement of strength can be regarded as the common "official business" of Xiao Yu and more than 100 races attached to Xiao Yu. In fact, the search for living things only occupies a very small amount of Xiao Yu's calculations, and most of Xiao Yu's computing power is still placed on scientific research and base construction.

At present, the most important problem in front of Xiao Yu is how to truly integrate antimatter technology into his attack and defense system. Of these two aspects, the attack aspect is the most important. Because in terms of defense, Xiao Yu has the four maintenance covers obtained from the Taihao civilization, so there is no need to worry too much about defense.

In terms of attack, Xiao Yu was sure that even the Molian civilization had not reached the level of miniaturizing the negative matter cannon. Many of their attack methods are still based on the grand unification theory that the fourth-level civilization has mastered. It's just that these attack methods, with the transformation of the fifth-level civilization, the attack power has increased by dozens of times.

In this regard, Xiao Yu has suffered a big loss. In the process of plundering the Azure Market, the phenomenon of dozens of spaceships besieging one of the opposing spaceships often occurs because of the lack of attack power.

Xiao Yu's main weapons now are antimatter cannonballs, matter disintegration beams, high-energy laser beams, gravity bombs, etc., and the conventional weapons of the Molian civilization are also these. It's just that the weapon system of the Molian civilization seems to be doped with antimatter technology, so it is much more powerful.

Xiao Yu's current task is to find these combinations. After mastering the four substances of positive matter, dark matter, antimatter, and negative matter, Xiao Yu has no obstacles in theory, and all that remains is the jishu problem.

One jishu puzzle after another, jishu obstacles, the total number has reached as many as 100,000 at present, and it can be yujian, as the old jishu puzzle is broken, there will be a new jishu puzzle born. At present, Xiao Yu has assigned these 100,000 jishu problems to scientists of various clans for a total of about 30,000, and Xiao Yu has taken on all the remaining 70,000 jishu problems.

The vast Central Academy of Sciences is full of robots and scientists of all races. In order to allow these scientists to be in the same environment, research together, and facilitate communication, Xiao Yu deliberately developed an extremely lightweight spacesuit, which is smoother than the softest silk in the Earth era, but much stronger in function than the most perfect spacesuit in the Earth era. Not only does it provide a comfortable environment for creatures to be in the same environment for scientists of different races, but it even has its own translation function, which can switch from different languages to any other language without barriers.

In order to solve the problems of racial barriers and different customs and habits, and to maximize efficiency and synergy, Xiao Yu has formulated a unified etiquette standard and a unified jishu standard for scientists of more than 100 races. Xiao Yu is trying to make these races truly merge together.

Under this means, in the Central Academy of Sciences, this often happens. In the wide hallway, an octopus-like creature and a lizard-like creature meet each other, and the two creatures, who seem to be incompatible, speak the same language at the same time, and make standard greetings at the same time. Even, the two of them stopped there for a while, briefly exchanged the results achieved in the recent period, and then separated and hurried to their own laboratories.

The laboratory is also a mixture of ichthyosaurs, there are huge giant-type creatures, there are flying intelligent creatures with wings behind them, and all kinds of creatures of different shapes are mixed together, but one thing is the same, that is, their knowledge, their knowledge structure. Here, regardless of race, size, they all strive for the same goal.

The huge Central Academy of Sciences covers an area of at least dozens of square kilometers, in which Xiao Yu has divided hundreds of major categories and tens of thousands of different research places such as the Institute of Biotechnology, the Institute of High Energy Particles, and the Institute of Antimatter Science and Technology. It has an extremely complete internal transportation system, and here, it is like a city. (To be continued......)
