Just when the earth crisis was smoothly passed and everything began to get on the right track, the mysterious voice in Luo Jia's mind became urgent again, it was the signal of the golden dome transmitting important technology.

Perhaps to emphasize the difference of this technology, the sudden and harsh sound of the smooth clicking made Luo Jia very painful, and his mind was full of confusion, so he had to leave the company and hide in the meditation center to retreat, waiting for the data to be transmitted.

Two days later, one morning, the harsh noise finally subsided, Luo Jia let out a long breath, the tense nerves were completely relaxed, after drinking a cup of black coffee, he went into the bathroom to rinse, and let the hot water quickly slap on his head, like a gentle head massage, and his thinking ability gradually returned to normal.

"If the transmission time is long enough, it should be some kind of very important black technology." Luo Jia wiped her body with a towel while pondering in her heart.

Coming to the sofa and sitting down, Luo Jia let the spirit enter the brain domain to search, and sure enough, he saw a newly appeared folder, and the lingua franca marked on it was the meaning of the engine.

"Engines? Is it warp engine technology!? ”

Luo Jia guessed, his emotions quickly became excited, facing the boundless stars, hundreds of light years away, without a powerful engine system, it was obviously impossible to complete the exploration.

Interstellar engine is one of the several essential pre-technologies of the road to the sea of stars, in addition to quantum computing, controlled fusion, hyperspace communication, gravitational wave radar and so on.

All in all, it is up to the starship to fly into space, and the performance of the starship is determined by the engine, no matter what language is used, it is by no means an exaggeration to describe the importance of the interstellar engine.

Luo Jia almost trembled and opened the folder, and what caught his eye were two subfolders, which were the electric propulsion engine and the jump engine.

"No, it won't!" Luo Jia's eyes widened, and he couldn't help but exclaim, he couldn't believe the generosity of the golden dome, and he actually teleported all the two major interstellar engine technologies.

Holding back his excitement, Luo Jia opened them one by one to make sure that his guess was not wrong, it was really interstellar engine technology, with these black technologies, the earth fleet would be equivalent to plugging in powerful wings, and distance would no longer be a problem.

Among the two technologies, electric propulsion is the foundation, and its principle has already been completed by the team led by Cao Yuan, and the successful reception of the technology of the golden dome allows Luo Jia to improve the speed and efficiency of the electric propulsion engine on the basis of the original.

In terms of function, electric propulsion actually relies on the reaction force generated by energy to drive the starship forward, and in normal flight conditions, such as starships docking at the dock and cruising around the planet, electric propulsion engines are used.

And if you want to travel through the universe, energy propulsion technology is far from enough, so you also need another one, the support of super mystical black technology, that is, space technology.

There are two kinds of engines derived from space technology, one is called the warp engine, unfortunately, the golden dome did not transmit this technology to Luo Jia, if you want to get it, Luo Jia may have to find it through other channels.

The other is called the jump engine, that is, the technology given by the Golden Dome luxury gift package, if you use the simplest language to describe the difference between these two space engines, it can be explained in this way, the warp engine is a super-light engine, and the jump engine is powerful, it is a super-light-year engine!

In other words, the maximum operating speed of the warp engine is faster than the speed of light, and the maximum operating speed of the jump engine is not only faster than the speed of light, but also reaches an incredible light grade.

In terms of speed, it seems that the jump engine is far better than the warp engine, after all, the jump engine can reach the speed of light, while the warp engine can only exceed the speed of light, and the difference between the two is huge.

But everything in this world has its own complexity, and it is not possible to distinguish the advantages and disadvantages of the two engines simply by speed, in fact, to create a warp engine, it requires an extremely perverted pre-technology, dark matter.

As we all know, dark matter is the core technology for the creation of destructive-level star-destroying weapons, and among the stars, the existence of dark matter is mastered, led by dark civilizations.

And since the dark civilization can build warp engines, it will almost certainly be able to build star-destroying weapons, and it is one of the most terrifying beings in the universe.

In contrast, the jump engine is much simpler, and it completes cross-space movement by spatial folding.

Although the jump engine can spawn space weapons, so far, Stellar has no record of space weapons, and it can be assumed that no one has successfully developed them, so they are relatively safe.

This is probably the interesting part of the world, everything has its two sides, the robot itself is not powerful, but an infinite replication ability, so that the robot has become the most terrifying existence in the universe, the technology involved in the jump engine is terrifying, but because the space weapon has not been developed, it seems that people and animals are harmless.

Luo Jia felt a little regretful, in the Golden Dome gift package, there was no warp speed engine technology, and he could not master dark matter and create a star-destroying weapon.

However, the jump engine technology is the fastest known way of interstellar navigation in the world, and with the jump engine technology, the small wrecking ball will be in place in one step, equaling the fastest speed in the universe, five light years per hour.

According to the information obtained from Black Sword and Blue Feather, there are not many civilizations that have mastered the jump engine, and the Galen Empire, which invaded the earth, used warp engines that were purchased, and they themselves did not master these two space engine technologies.

In addition to being delighted, Luo Jia read excitedly, consistent with the information he had learned before, the jump engine uses two technologies: spatial folding and spatial puncture.

To put it simply, space folding is like when you look at a map, you will find that Tokyo and Paris are separated by a long distance, one in East Asia and the other in Western Europe, as if they are out of reach, even if you take a jetliner, it takes up to ten hours of long flight.

However, if you fold the map from the middle, the two points are opposite, and the distance between Tokyo and Paris becomes the thickness of a piece of paper, which is the spatial folding technology, and with the spatial piercing technology, a temporary wormhole between the two points is opened, and the starship can cross a long time and space as long as it passes through the wormhole.

According to technical data, Golden Dome's jump engine technology can span up to five light-years per hour, and the whole process takes only a few minutes, but because the jump engine needs to dissipate heat and gather huge energy before use, it can only be activated once an hour.

As time passed, Luo Jia was ecstatic to review her newly acquired knowledge.

The expeditionary fleet of the Galen Empire passed through the fixed wormhole and took one year and seven months before reaching the solar system.

With the Jump Engine, the Earth Fleet can enter the territory of the Galen Empire in a matter of days!

Before you know it, the situation is taking a striking turn!
