At this moment, under the impact of huge energy from the inside of the atomic nucleus, a cavitation bubble directly appeared on the seabed, which was tens of thousands of meters deep and had a huge pressure unimaginable to ordinary people.

Under the extreme heat and pressure, the surrounding sea water has undergone strange changes. They can no longer sustain liquids, nor gases, nor solids, but plasma.

The huge energy and shock wave centered on the detonation point and spread to the periphery at an extremely high speed, instantly enveloping a radius of several kilometers. Mu Gongying, who was within this range, all died in an instant.

At this moment, I don't know how many billions of lifeforms were destroyed.

Mu Gongying, who was far away from the nuclear explosion, was not affected too much, at least not to die directly. But it doesn't matter, they don't have a chance to make a comeback at the moment.

Because the uranium-235 in the original Z bomb could not be fully fissioned at the moment of nuclear explosion. In fact, only about one kilogram of the 16 kilograms of uranium used in the original Z bomb made by Chen Yue was involved in fission.

The remaining 15 kilograms of highly radioactive uranium-235 were directly dispersed with the occurrence of a nuclear explosion.

Since then, this area has been highly radioactive.

These uranium-235 acts like a pesticide and can spread as the sea water flows. At least for a dozen years, radiation in this area will not be reduced much. During this time, this area was a Jedi for Mu Gongying.

Come as much as you want to die.

"It's finally clean."

Chen Yue sighed and sent a submarine to sink again. This time, he was not harassed by Mu Gongying again, and successfully let him carry out the seabed exploration mission.

After the planning was done, the next step was to transport a large number of high-performance subsea building materials, and the construction of a subsea base directly began here.

This submarine base will not only undertake the mining, preliminary processing and transshipment of various precious mineral deposits on the seabed, but also a scientific research base.

"Jupiter can't go around it. If it continues, one day I'll get into Jupiter to mine resources. Think of Europa's deep ocean as an environmental simulator of Jupiter's atmosphere. ”

A large number of submarine construction machinery was developed by Chen Yue and sent directly to the seabed. As a result, the once dead and silent seabed began to bustle and lively.

Robots shuttle back and forth, huge submarine excavators roar and tremble, digging out the ore one by one under the extremely high water pressure. Trucks loaded with ore drove directly along the seabed, bringing in a large amount of undersea explosives and blowing up the hard rocks that the machinery could not cope with......

They eventually produced a variety of minerals that were extremely important to Chen, which complemented Chen's increasingly extensive industrial facilities.

At this stage, Chen Yue's industrial base has spread almost all over the world of Europa. Hundreds of thousands of factories of all kinds roar day and night, various precision experiments in the laboratory produce data day and night, and trains speed day and night on the criss-crossing roads.

There are spaceships and satellites in space. There are specially made helicopters flying tirelessly around in the atmosphere, trains on the roads, trucks, and submarines on the seabed.

On land, sea, in the air, every place has Chen Yue's footprints.

At this time, Chen Yue had planned for a long time, but he had never been able to really implement one thing, and he could finally do it.

Neutrino telescopes.

In the past, because there was no suitable environment, there was too much and too much external background radiation, which would seriously interfere with the observation of neutrino telescopes, so Chen Yue never built it.

Now that Chen Yue is truly capable of operating in the deep sea, the time is finally ripe for the construction of a neutrino telescope.

The thick Europa Ocean acts as a cover, keeping most of the radiation out. Only highly penetrating neutrinos can penetrate it. In this way, an environment is created for the study of neutrinos.

Neutrinos play an extremely important role in the evolution of the universe. It plays an important role in many physical processes such as supernova explosions, black holes, neutron star mergers, galaxy mergers and evolutions, and stellar physics.

The study of it will help to increase Chen Yue's understanding of fundamental physics.

So, hundreds of kilometers away from this undersea base, in a huge underground crack, the submarine controlled by Chen Yue sent a large amount of building materials and machinery.

It is more than 100,000 meters above the surface. Above here, there is more than 60 kilometers of water deep, and then more than 40 kilometers of ice.

In particular, the geology is stable here, and Europa's core motion caused by Jupiter's gravity does not affect here. The environment here is also relatively pure, with almost no radioactive material and very low background radiation.

In this environment, huge seabed research bases are slowly being built. The strong water pressure is directly blocked by the high-strength steel structure, and the interior is dry and pure, just like the research institutes that Chen Yue built on the surface.

Directly above this undersea base, on top of the thick ice, Chen Yue built a nuclear power plant to provide it with energy and for communication transit.

There is a submarine cable connection of more than 100 kilometers long between the two.

Inside this undersea base, Chen Yue assembled a huge ball with a diameter of 100 meters. The sphere is connected to a dense network of fiber optic cables on the outside, and millions of photomultipliers are installed inside.

Once it was built, work began on an ultrapure water plant elsewhere on the base.

It takes water directly from Europa's ocean and begins its purification work. Any impurities mixed with the water will be removed.

This rejection even reaches the molecular level. Chen Yue has specially developed a water purifier with an accuracy that can reach the molecular level, so as to make the water as pure as possible.

Chen Yue's technical precision is obviously not able to reach the level of human civilization at its peak. However, Chen Yue also has his own advantages, that is, he can do something at any cost, regardless of the cost.

Anyway, for him, the so-called cost is actually just the share of computing power.

In this way, there is an effect similar to "Lida Flying Bricks".

My accuracy is not as good as yours, but if I can't do it once, I will refine it twice, if I can't do it twice, I will refine it three times, and if I can't do it, I will refine it hundreds of times, thousands of times, and I can always produce ultrapure water that meets the standards.

What? Not financially cost-effective? Consuming too many resources? Too expensive?

What is the economy? What is the cost?

Chen Yue said I don't know. I just know that allocating some share of computing power will solve the problem.

In this case, more than 500,000 tons of ultrapure water were created by him little by little.
