The dense spot of light emitted by the six-clawed giant lasted for more than three months.

It wasn't until the beginning of the 8th year of Galaxy that the various cosmic monitoring stations did not detect dense light spots, and there were still occasional light spots or two.

This is obviously the result of the civil war of the Six-Claw civilization.

However, which side won, the Space Reconnaissance Department did not analyze.

However, in the three months of fierce fighting, the Space Reconnaissance Department detected at least 286,000 flashes of light, which means that at least 286,000 nuclear bombs were detonated during the fierce battle of the six-claw civilization civil war.

It's terrifying.

You know, this is not a miniature hydrogen bomb used by Homo sapiens to propel spacecraft, but a nuclear bomb that starts with a yield of tens of thousands of tons at every turn, and is generally in the million-ton yield.

This shows how cruel the civil war of the Six-Claw civilization was.

And the internal war of the Homo sapiens civilization has also released a lot of relevant information within the company, so that all employees can feel a small "six-claw shock".

Moon.

In the middle of the Mendeleev crater on the back.

There is a small base here, called the city of Mendeleev Base.

The base city is mainly engaged in the research of spacecraft and is part of the Space Division, and a new engine is being tested inside the base.

Even Mikoyan came in person, and the person in charge of researching this new engine was Karl.

Engineer Carl was previously engaged in the research and development of aero engines, and later with the major aviation groups of Homo sapiens, the in-depth research and development of aero engines, and the blowout of various talents, Carl felt that he should do something new.

The Space Division's exploration of outer space, coupled with the invitation of an old friend, Karl Engineer chose to transfer to the Space Division.

That's more than four years.

Today we finally have to accept the results.

"Carl, are you sure?" Mikoyan's synchronized robot had a hint of concern on his face.

Because the previous research work on the spacecraft engine at the Mendeleev base was not going smoothly, it was not that there was a problem with the scientific research level of Karl and others, but that the direction of their research was very difficult.

The direction of space engine research in the city of Mendeleev is nuclear fusion engine, and it is not a nuclear explosion propulsion engine.

Previously, they studied on Earth for two years, and as the progress of lunar development improved, the Space Division moved the research institute to the far side of the moon, and Carl's team studied on the far side of the moon for more than two years.

During this time, their research has been in the dystocia phase.

Today's test made Mikoyan have to worry too.

"Don't worry! This time I was confident. Carl's sync robot was full of confidence.

Through the observation window, the two of them could see a huge space engine test platform, and a large engine with a nozzle diameter of about 5 meters was being installed.

A large number of synchronous robots are busy checking and preparing for the next first measurement.

The fusion engine designed by Karl's team uses a variant of the tokamak device.

Specifically, the closed toroidal magnetic field of the tokamak device is transformed into a closed toroidal magnetic field combined with an open spiral magnetic field.

Among them, there are six tokamak rings, and there is only one spiral magnetic field, and between the six tokamak rings and the spiral magnetic field, the channel can be opened or closed.

Among them, the technology of the tokamak ring has been difficult to produce before, not that it cannot generate electricity, but that the Q value (production ratio) is too low, even if the technology of Homo sapiens is strong, there has been no way to refresh the Q value to 3.

In addition, it is very difficult to miniaturize tokamaks.

It wasn't until Dr. Levi's improved the tokamak device, using tail field acceleration and magnetic field binding, plus the plasma heating technology of Gamma rays, to reassemble the later variant of the tokamak ring.

The tokamak ring of the variant not only easily heats the atomic temperature to 1.27 billion degrees Celsius, but also increases the atomic acceleration by an order of magnitude, and the control accuracy is also further improved.

An improved version of the tokamak ring, also known as the "Levi's ring", has a very fast fusion reaction, and the raw material can also be made of ordinary hydrogen atoms, without the need to refine heavy water and other radioactive elements.

Of course, Levi's rings can also carry out other nuclear fusion reactions, such as helium fusion, lithium fusion, beryllium fusion, and boron fusion.

In other words, in the Levi's ring, after hydrogen is introduced, hydrogen fusion will be carried out first, and after hydrogen is converted into helium, helium nuclear fusion will be carried out, and so on.

This advantage is really powerful.

Not only has the Q value of nuclear fusion been increased to 76.2, but the fuel for nuclear fusion is no longer limited to radioisotopes such as heavy hydrogen and helium 3.

This advantage allows the spacecraft to easily obtain nuclear fuel during interstellar space voyages.

Although interstellar space seems empty, it is actually densely packed with a large amount of interstellar stardust and asteroids.

If the six-clawed ship's fugitive ship had mastered the Levi Ring, they wouldn't have been wiped out because they couldn't get supplies.

After all, in interstellar space, the core ingredient of stardust is hydrogen helium, and asteroids contain water ice, which can also be used to refine hydrogen.

Levi's rings can carry out multiple controlled nuclear fusions, which can squeeze a hydrogen element to the extreme.

Now the Earth headquarters has begun to phase out the nuclear fission reactor and is ready to fully upgrade it to a Levi's ring nuclear fusion reactor.

The Levi ring also has another advantage, that is, it can be miniaturized, and the smallest Levi ring prototype is only about 372 tons.

This weight is miniaturization for Homo sapiens' spaceship.

After all, the combination of nuclear explosion furnace technology, equipment and auxiliary buildings can easily start at hundreds of thousands of tons, and there is no way to cram into a spaceship.

This is also the reason why the Space Division directly adopted the nuclear explosion propulsion scheme at the beginning, and did not use furnace nuclear fusion.

The Levi's ring ton equipment can be compressed to several hundred tons, which is not heavy for medium and large spacecraft.

That's why Engineer Carl dared to use the Levi's ring as the power of the spacecraft.

Of course, since outer space is different from Earth, Carl's team will definitely need to adjust the Levi's ring, as well as redesign the plan to tune the engine.

At present, the Carl team is the fastest research progress among all contract engine teams, and even the prototype has been made.

It's just that this prototype is a bit heavy, with six Levi's rings, plus the spiral magnetic field device, the total weight reaches 3,521 tons, which can finally be installed in a large spacecraft.

After more than half an hour of final checks, the prototype was finally ready to be tested.

Soon Karl engineers took Mikoyan and others to the control room of the test platform.
