Because when their discussion ended, it was already the second year that Zhu Lei had ascended the throne and became the emperor of the Ming Empire.

In the past two years, the most important project for the Ming Empire to start is to make a collar for the stars, that is, the stellar energy harvesting technology project has been launched, in fact, this is also one of the core projects of the Ming Empire's ultra-long-range wormhole group and portal technology, after all, whether it is an ultra-long-range wormhole group or a portal in the future, it is inseparable from the support of energy.

The stellar collar currently under construction is the source of energy for ultra-remote wormholes and dimensional portals.

After all, whether it is a long-range large wormhole group or a super-large dimensional portal, it is a large energy consumer, if this technology is not used, the Ming Empire is simply unable to provide enough energy for these two large energy consumers, and this technology that has been proposed in the Earth period has given energy solutions.

Generally speaking, when the technological civilization in the universe reaches the fifth level of civilization, they will try their best to collect the energy emitted by the stars.

Once the civilization level reaches level 5 or above, the demand for energy is very huge, and generally speaking, although the level 5 civilization has mastered a lot of energy technology, such as controllable nuclear fusion technology, dark matter energy technology and various energy crystallization technologies, but these technologies cannot meet the basic energy needs of the entire civilization, so the most common item in the universe, that is, the energy emitted by stars, has become one of the main sources of energy acquisition for major civilizations.

There are many ways to obtain stellar energy, it can be said that 99 civilizations have 99 different collection methods, scientific and technological civilization has scientific and technological civilization collection methods, biological civilization has biological civilization collection methods, energy civilization has energy civilization collection methods, and the collection methods and collection efficiency of major civilizations are very different.

Some civilizations only have less than one percent of the energy utilization rate of the stars, while some civilizations can infinitely close to all the energy emitted by the stars, of course, when the civilization level reaches the fifth level, basically all civilizations have more than 50% of the energy emitted by the stars.

Take the current Ming Empire as an example, although the Ming Empire has also mastered controllable nuclear fusion technology, dark energy technology and energy compression technology, and even the Ming Empire has mastered the technology of extracting energy from spirit stones, but these technologies are basically still used in the military, even if it is the lowest-end controllable nuclear fusion technology, it is rarely used in the civilian except for civilian spaceships.

In addition to controllable nuclear fusion technology, there is also dark energy technology, this technology is impossible for the Ming Empire to popularize among the people, after all, it is equivalent to ordinary energy, dark matter is too dangerous, and a little carelessness may cause extremely serious consequences, so dark matter must not be popularized in the people on a large scale in this stage of civilization.

Of course, the last is the spirit stone energy, although the energy in the spirit stone is quite huge, and the danger is not high, compared to other people, the energy contained in the spirit stone is already very safe, so it stands to reason that the spirit stone has the conditions for large-scale popularization.

However, due to the particularity that the energy in the spirit stone can be absorbed by living beings, it is destined that its energy cannot be used for other purposes, not to mention that because the spirit energy is one of the highest levels of energy in the universe, it is very troublesome to convert it into other energy, and even the energy consumed in the conversion process is very huge, so even in the current Ming Empire, the spirit stone, as an auxiliary energy for cultivation, has become one of the other currencies of the Ming Empire.

And as the population of the Ming Empire increases, there are naturally more and more cultivators, so resources like spirit stones are naturally consumed more and more, so it is impossible to use them in other places, after all, there are ways to use energy in industry.

Therefore, the Ming Empire is still on the same path as other civilizations to use stellar energy on a large scale, but unlike other civilizations, although other civilizations also have projects like the Ming Empire, using stellar collar technology to obtain the energy of stars, but most civilizations are not like this, although these civilizations also use various methods to obtain the energy of stars on a large scale, but not all civilizations have the ability to build a huge stellar collar for the stars.

Although the construction of the stellar collar is huge, it is even an incompleteable project for many civilizations in the galaxy, but it is still very easy for the current Ming Empire, not to mention the civilization level of the empire and the level of sixth-level civilization, although such a project is huge, it only takes a little more time, and secondly, many of the empire's current projects do not need to be built by people themselves, and they have basically been completed by robots controlled by artificial intelligence, And this stellar collar project will also be completed by these artificial intelligence, of course, not all of them will be completed by robots, a small number of engineers and experts still want it, although the artificial intelligence technology of the Ming Empire is advanced, far beyond other civilizations in the galaxy, but robots are robots after all, and they are far from being compared with human beings themselves.

And basically each civilization uses different methods, some civilizations use steel-like materials to surround the entire sun, some use solar sail panels, and some use plants to carry out, but basically they are all the same, basically to surround the entire star, after all, only in this way can we maximize the energy of Hengchang.

After all, if you want to get more energy from the star, you must be as close as possible to the star, but each star has a strong gravitational force, and because the star will produce a huge centrifugal force in the process of rotation, it must surround the entire star, only in this way will it not be thrown away by the strong centrifugal force.

And the Ming Empire is now a sixth-level civilization because the civilization level is already a sixth-level civilization, so it will definitely not use the technology of the low-level civilization to build a stellar collar, but use the magnetic field technology and space technology that the Ming Empire has mastered to combine to collect various energies emitted by the stars, this technology can be very effective to collect the energy of the stars, and even in terms of energy utilization has reached an unprecedented 95% or more.

In fact, once this technology is verified and feasible in this project, then the entire Ming Empire will not lack cheap and efficient energy in the future.
