After Zhu Lei came back, he did not sleep in the gentle township, and on the third day after returning home, he plunged into his laboratory to study the warp engine, the most important long-range navigation method in space, in fact, the Ming Empire's research on the warp engine began as early as the Ming Empire just entered the space age, because both Zhu Lei and the Ming Empire's high-level and scientists are very aware of the importance of the warp engine.

Although the Ming Empire has now conquered the card civilization more than ten light years away, the distance of more than ten light years is only an insignificant distance for the entire galaxy or the universe, but for the current Ming Empire, although it is not out of reach, but a round trip is at least half a century.

This is still the speed of the most advanced spaceship of the Ming Empire, if it is an ordinary civilian spaceship, even if it is half a century, it will not be able to run back and forth.

Half a century back and forth, even if the citizens of the Ming Empire have a long lifespan, they can't afford it.

Although the Ming Empire has been in Zhu Lei's expedition to the Kara civilization for more than half a century, the development of the Ming Empire has been much slower than before, after all, the higher the degree of development of civilization, the higher the difficulty of each technological breakthrough, so the Ming Empire began to slowly precipitate.

However, there are some technologies that the Ming Empire has to concentrate on striving for a breakthrough in a short period of time, and the number engine technology is one of them.

The Ming Empire is like arriving in the galaxy where the Kara civilization is located in a short period of time, and there are two methods that are most likely to be realized now, one is to use technology to achieve the other is to use the method of cultivation, the method of using technology is to develop a warp engine, and the method of using cultivation is to break through the cultivation of earth immortals in a short period of time and use the interstellar teleportation array to achieve.

But the method of using cultivation seems to be far away now, after all, the person who has cultivated to the highest level in the entire Ming Empire is only in the Yuan Infant Stage, and it is only in the early stage, so it is impossible to break through the cultivation of the Earth Immortal in a short period of time, not to mention that it is not so easy to break through the Earth Immortal and go through the Heavenly Tribulation, so without the accumulation of tens of thousands of years, it is impossible for anyone in the human race to break through the cultivation of the center of the earth.

What's more, even if someone in the Ming Empire breaks through the Earth Immortal now, being able to arrange the interstellar teleportation array is a drop in the bucket for the Ming Empire, after all, the interstellar teleportation array arranged by the cultivation means has great limitations, and it is not practical for the Ming Empire at all.

Because of the interstellar teleportation array arranged by the cultivation means, the minimum cultivation required by the teleportation personnel must also be above the primordial infancy, because those who are below the primordial infancy stage cannot withstand the pressure generated by the interstellar teleportation at all.

What's more, the interstellar teleportation array can only teleport a few people per teleportation, and the largest interstellar teleportation array cannot exceed ten people per teleportation, and with the current strength of human beings, even the materials used by the interstellar teleportation array cannot be made up by the Ming Empire.

Therefore, the warp engine has become the first choice of the Ming Empire, and the warp engine, also known as the curvature engine, is a faster-than-light propulsion system, so it is also called the outer faster-than-light engine.

The warp engine is actually nothing new, and the concept of the warp engine has been proposed by humans as early as the Earth era.

The warp engine uses the distortion and jump of time and space to complete faster-than-light flight, and Zhu Lei learned in the mall that the warp engine is the most commonly used means of navigation for most interstellar civilizations, and the warp engine is also an engine technology that must be possessed in the intermediate stage of intermediate civilizations.

Therefore, if the Ming Empire wants to successfully advance to the intermediate intermediate civilization, it must also develop warp engine technology, otherwise no matter how advanced other technologies are, it will not be able to become an intermediate intermediate civilization, or a fifth-level civilization in the galaxy.

The method of warp speed navigation has been proposed as early as the earth period, although it is said that it was impossible to realize it with human technology at that time, but it was provided by the current Ming Empire.

If the magnetic field is strong enough, then the spacecraft will enter the higher dimensional space and fly faster than the speed of light, and when the spacecraft's magnetic field disappears, the spacecraft will enter normal space.

Although it is very simple to say, it is very difficult to achieve warp speed flying, but Zhu Lei has to admire the people of the earth era, you must know that the technology at that time is simply the difference between heaven and earth compared with now, but it is in such a primitive era that people also put forward the concept of warp speed navigation.

After Zhu Lei's understanding of the mall, he found that the concept of warp navigation proposed by the human earth was very correct, but if you want to develop a warp engine, you need materials, energy and methods.

In terms of material development, it is the strength of the Ming Empire, so even if the materials for warp speed navigation are difficult, there is no difficulty with the current strength of the Ming Empire.

In terms of energy, the Ming Empire also has controllable nuclear fusion technology, after all, the warp engine uses a strong magnetic field to form a strong force field to resonate with space, so that the spacecraft can enter a higher dimensional space, so the energy required is very powerful, ordinary energy can not provide such a powerful energy at all, and the most powerful energy of the Ming Empire now is controllable nuclear fusion technology.

Although the Ming Empire has the conditions in terms of materials and energy, and in terms of methods, the predecessors have found the direction of the Ming Empire, but the Ming Empire has been working hard to develop warp engine technology since it entered space, but it has been nearly 100 years since the Ming Empire entered space, but it has not yet developed a mature warp engine.

But in fact, compared with other cosmic civilizations, the Ming Empire has a great advantage in the development of warp engines, after all, the predecessors of mankind have provided a way to realize the warp engine for future generations, but the Ming Empire has only been in the universe for more than a hundred years now, and the precipitation in this regard is not enough, as long as it continues to develop along its current path, it will not take a few hundred years for the Ming Empire to develop warp engine technology.

After all, it has been less than 100 years since the Ming Empire entered space, and it has not taken thousands of years to study the warp engine, and it is absolutely impossible for the Ming Empire to study the warp engine in this short period of 100 years, even if the development potential of human beings is high, its technical difficulty is there, and it is impossible to make a breakthrough in a short period of time.

Therefore, Zhu Lei had to enter the laboratory to study the Qufu engine in person in order for the spaceship of the Ming Empire to be able to achieve warp speed navigation as soon as possible, and before entering the laboratory, he spent all his wealth in the mall to buy the warp engine technology that is about the same level of technology as the Ming Empire's current development, after all, if the technology is too different, the Ming Empire will not be able to manufacture it.
