From the information transmitted by the square, monument-like object, Mu Kange learned about the members of the Genius Club. Ling Hao was the forty-second. What shocked him was that three of the forty-two members of the Genius Club were human!

Aside from Ling Hao, the remaining two human members are Chen Yang and Lu Yuan. Mu Kange knows that the former is the Demonic Cult Master Mars King, but he doesn't know about the latter.

The Black Paper of All Souls releases a new card pack every ten years. If any major events occur during this period, additional card packs will be released. The reason for the ten-year interval is that the Galactic Battle Tournament is held every ten years.

However, the Human Federation, as a newly emerging civilization, was severely humiliated in the Galactic Battle Tournament in its early years before it became so competitive. Therefore, it has not participated since, and is preparing to catch up with the average level of interstellar civilization.

However, the Human Federation did not participate in the Galactic Battle Tournament, which resulted in the Human Federation having few character cards, making it inconvenient for Mu Kange to learn about the strong individuals of his own civilization, even though the Human Federation didn't have many cards to begin with.

Afterwards, Ling Hao went to the warehouse to select some items and sent Mu Kange outside. This distance was just enough for Mu Kange to see Yin Xin.

The galactic center is very different from the Orion Arm, where there is a terrifying density of almost 300,000 stars per cubic light-year.

This is roughly equivalent to stuffing millions of stars into the solar system, and most of these stars are in their late middle or late stages of life, so they are significantly larger in size and brightness.

This is arguably the most dangerous region in the entire Milky Way, and the most hostile place to life. The numerous old stars are like ticking time bombs, constantly threatening the safety of life on other stars around them.

Besides the old stars, the galactic center also has frequent supernova explosions, and because it is so crowded, the stars in the galactic center often collide and explode, generating waves of rapidly spreading energy.

Therefore, in this region, apart from nuclear molecular nebula life forms that are born in a high-pressure, high-temperature environment, other conventional carbon-based, silicon-based, sulfur-based, alkyl, amino, nitrogen-based, fluorine-based, and mercury-based organisms cannot be born or survive.

The most terrifying thing in the galactic center is undoubtedly the black hole with an event horizon diameter of 24 million kilometers and a mass of about 4.3 million suns.

The Galactic Heart civilization has the highest level of technology in the entire galaxy, so the things they build are extremely shocking to outsiders. For example, Mu Kange is completely mesmerized by them.

Unlike the silly Dyson sphere, which is more symbolic than practical, building a Dyson sphere or Dyson ring requires a huge amount of material and has high technical and engineering barriers, requiring at least a high level of space exploration.

Even if all the planetary material in the solar system were dismantled, it wouldn't be enough to cover the entire sun; it could only cover a small portion to a limited extent.

At the same time, the cost of building it is disproportionate to the potential benefits. A low-level civilization might burn itself out before it is even finished building a Dyson sphere, while an advanced civilization capable of building Dyson spheres and Dyson rings would not need such an inefficient way of obtaining energy at all.

The civilization at the center of the galaxy built a Penrose sphere around the black hole at the center of the galaxy, which is a large energy extraction device that continuously extracts a large amount of thermodynamic free energy from the black hole through the Penrose process.

Generally speaking, as a black hole rotates, it drags the surrounding spacetime, thus forming a region called the "ergosphere" outside the event horizon. In this region, because three-dimensional spacetime is dragged to its limit by the black hole, objects inside it will not appear stationary to observers in more distant cosmos.

Because the ergosphere is outside the event horizon of a black hole, objects entering this region still have a chance to escape. If, when throwing matter into the black hole, the appropriate speed and angle are chosen to enter the ergosphere and then automatically disintegrate, some of it will fall into the event horizon, while the other part will fly out of the ergosphere.

Therefore, as long as the trajectory is appropriate, the kinetic energy of an object flying out of the outer energy zone of the black hole's event horizon will exceed the kinetic energy of the object flying into it, and this excess kinetic energy comes from the rotational kinetic energy of the black hole itself.

However, what the Galactic Center civilization built was not simply the Penrose sphere. In terms of appearance and function, this super-megastructure is actually more like a planet!

Yes, planets.

The super-giant structure built by the Galactic Heart Civilization envelops the entire Galactic Heart. Mukange doesn't know its thickness, but it is at least tens of thousands of kilometers thick.

Its surface is covered with rivers, lakes, seas, mountains, continents, and thousands of different natural environments, both mild and extreme, which is why Mukangge thinks this thing is like a planet.

After all, you can't exactly call it a star, can you? What star has this kind of terrain?

"This is fucking outrageous." Mu Kange didn't dare to imagine how many resources the Silver Heart Civilization consumed when building this thing. The energy required to maintain it every day was probably equivalent to the total energy produced by the Human Federation over countless years.

Spectacles ruin a country! Spectacles ruin a country.

However, is this really such a huge drain on the Silver Heart civilization?

As a superior civilization in the galaxy, they are able to extract a large amount of vacuum zero-point energy from the Dirac Sea with extremely small amounts of energy, and the vast amount of dark matter and antimatter in the universe are also their energy source.

Furthermore, as revealed in the Black Paper of All Spirits, they even have other, more advanced methods to directly mine black holes as mineral deposits, reducing their mass while obtaining an equivalent mass-energy equivalence.

Primitive organisms viewed air as something to breathe, but for advanced civilizations, it is fuel.

Primitive organisms viewed water as the source of life and an essential element of life, but for advanced civilizations, it is also fuel.

Primitive beings viewed stars as the most noble things in the world and gave them various forms, transforming them into all sorts of gods. But for advanced civilizations, they were still fuel.

This is what is called technology. With the development of technology, all things in the world are gradually becoming unified. Therefore, in the eyes of the Galactic Heart civilization, black holes, this mysterious and terrifying natural boss, can also be mineral deposits.

Mu Kange couldn't really comment on it, but this thing was truly spectacular. However, since the Silver Heart Civilization had already used the name of the Silver Heart Black Hole as the name of its civilization and race, he didn't dare to go there. It wouldn't be good if he wandered around and got caught.

"Kan, stop looking, it's time to go back." Ling Hao's voice came from behind Mu Kange, and the simple-minded boy, hearing his older brother's call, followed Ling Hao back to the car dealership.
