After Zhu Lei and they finished probing the entire life planet, they flew towards their intended target.

At this time, the Ming Empire, thousands of light-years away from them, was designing and building a new type of new-generation spaceship.

Compared with the real spaceship, the mothership-level spaceships built in the past are about the same size as the motherships in terms of size and tonnage, but there are great differences in function.

The tonnage and size of the mothership do not necessarily exceed those mothership-level spaceships built by the Ming Empire in the past, but the most important factor of the real mothership is to have the ability to develop and produce space fighters and space warships, which puts forward higher requirements for the performance of spaceships, that is, space carriers, which also leads to the fact that only real sixth-level civilizations can build such warships.

In fact, the space carrier can also be called the space industrial ship, this kind of space mother ship is more huge than the general spaceship, after all, a mother ship must have a complete warship construction industrial system, in addition to strong attack and defense capabilities, as well as far beyond the flight ability of ordinary spaceships, so if you want to really build a space mothership, it puts forward higher requirements for the entire civilization industrial system.

The real space carrier designed by the Ming Empire this time has a diameter of more than 700 kilometers, so it is impossible for a space warship like this to be built in the solar system, after all, such a huge spaceship can already affect most of the planets in the solar system.

After all, after hundreds of years of development, the industrial development of the Ocean of Light has changed from what it used to be, even compared with the heart solar system of the Ming Empire, the most developed region of the Ming Empire, and it has the ability to build spaceships of more than 500 kilometers.

However, the construction of an 800-kilometer-level spaceship this time is also an industrial spaceship, that is, a mothership, which is also a great test for the industrial system of the entire Ocean of Light and the technology of the entire Ming Empire, and before that, the Ming Empire had no experience in building such a large spaceship, let alone a shipyard that could accommodate such a large spaceship.

Therefore, before building this huge space carrier, it is necessary to build a dock that can accommodate such a large spaceship, after all, all the shipyards in the entire Ming Empire, including the Yongan Group controlled by Zhu Lei, can only make the largest spaceship only 500 kilometers level, so the first thing is to build a dock that can accommodate a thousand kilometers of spaceship level, after all, the spaceships of the Ming Empire will be built bigger and bigger, so the dock must also flow out of the necessary space, In the future, even larger spaceships can be built.

The task of manufacturing the space carrier will be undertaken by Zhu Lei's Yongan Group, and Zhu Lei's Yongan Group has settled in the Ocean of Light as early as the beginning of the Ming Empire's control of the Ocean of Light, and its industrial level has far surpassed that of other shipbuilding groups in the Ocean of Light in the past few hundred years, including the official shipyards of the Ming Empire.

In the entire Ocean of Light, the Yongan Group shipyard has mastered the most advanced shipbuilding technology and dock construction technology of the Ming Empire.

Of course, the largest spaceship built by Yongan Group before this was about 500 kilometers in diameter, and the largest spaceship built by other shipyards was only about 300 kilometers, which was still made by the official shipyards of the Ming Empire, and the largest spaceship manufactured by other unofficial shipyards of the Ming Empire was only less than 200 kilometers, which is a big difference.

However, this is already very remarkable for other private shipyards, after all, these shipyards do not have a client of the plane mall like Zhu Lei, so they do not have a more advanced technology source like Zhu Lei.

And other civilian shipyards in the Ming Empire, the shipbuilding business they mainly undertake is basically a civilian spacecraft, and the requirements for the performance of the spacecraft are not as high as those in the military, so the two-hundred-kilometer spaceship is enough, not to mention that these civilian shipyards also have their own advantages, that is, the cost advantage, compared with the official shipyard of the Ming Empire and Zhu Lei's Yongan Group shipyard, the shipbuilding price of spaceships of the same level, other civilian shipyards is only 3/ 5, 2/5 of the official shipyards, so the viability of these shipyards is still quite strong.

The main business of official shipyards is to manufacture all kinds of medium and large space warships, so what these shipyards like most is to use relatively mature technology, after all, mature technology means safety and reliability, which is very important for military space warships for the purpose of war.

And Zhu Lei's Yongan Shipyard is to manufacture the most advanced space warships of the Ming Empire and explore the manufacturing method of higher-level spaceships, but the greater the risk of Yongan Group, although the price of advanced spaceships is very expensive, the profits are super high, but once it fails, it means huge losses, but this is not a big deal for Zhu Lei's Yongan Group, after all, human beings want to become a higher civilization, the exploration of advanced technology is necessary, and they want to explore more advanced technology. Then you can't be afraid of failure and not develop.

At this time, in the Yong'an Galaxy of the Ocean of Light, a huge dock is being installed, this week is a galaxy specially assigned by the Ming Empire to the Yongan Group in the Ocean of Light, its main purpose is to make various super-large spaceships, this galaxy is compared to other galaxies, a special place is that there is no star in this galaxy, so there is no place where large spaceships affect the trajectory of the planets in the galaxy, and there are a huge number of various resources in the vicinity of this week, It can be used as a resource for making a spaceboat.

However, at this time, this dock has just begun to be installed, and all kinds of ultra-high-precision parts that have been transported from all corners of the Ocean of Light have been accurately installed in the position where they should be located by various installation robots, after all, it is very difficult to build a dock that can manufacture a thousand-kilometer spaceship, even the Yongan Group, which has the most powerful scientific and technological strength in the Ming Empire, does not dare to have the slightest carelessness, once there is a problem, it will affect the manufacturing of the entire dock, and may even lead to the construction of spaceships in the future. It is the ship's undesirable conditions that cause the spacecraft to be destroyed and killed due to these defects during spaceflight or combat.
