I really didn't want to practice immortality at Hogwarts

"Dyson ring?" Hermione was stunned when she heard the name.

Although Hermione still knew something about Muggle science, the Dyson ring was such an avant-garde concept after all, so it was understandable that Hermione didn't know about it.

Zhang Chun quickly explained to her that if he wanted to explain clearly the so-called "Dyson ring", he had to first talk about "Dyson sphere".

"Dyson sphere" is a theory proposed by Freeman Dyson in 1960.The so-called "Dyson sphere" is actually an artificial celestial body with a diameter of 2 million kilometers, which is used to surround stars and mine stellar energy.

This is a natural nuclear fusion reactor using stars as a power source.

The energy contained in a planet like the Earth is very limited, which is far from enough to support the development of civilization on it to an advanced stage; and in a star-planet system, most of the energy - the radiation from the star - is used up. It is wasted. Currently, the planets in our solar system only receive about 1109 of the solar radiation energy.Dyson believes that a highly developed civilization must be able to surround the sun with a huge spherical structure, so that most of the sun's radiation energy is intercepted. Only in this way can the civilization be supported for a long time and develop to a sufficient height. .

All stars emit ruthless and endless energy, but this energy is generally scattered throughout the universe.

For example, this is the case with the sun, which is the core star of the solar system. It is the endless energy emitted by its nuclear fusion that brings endless energy to the earth and other planets.

The "Dyson Sphere" that wraps the sun uses a spherical engineering product to directly cover the sun and collect the resources above.The essence is to use the sun's nuclear fusion energy as much as possible to provide energy for civilization on the planet.

After all, the "Dyson Sphere" is an energy harvesting device.But this kind of ultra-large-scale project in the universe is not something that anyone can do if they want to.Generally speaking, it must at least reach a second-level civilization that can carry out interstellar travel. Only this kind of civilization that can try to control the speed of light can give stars a hypothetical "Dyson sphere" to harvest energy.

The problem is that the Dyson sphere requires too much material and is too complicated.Therefore, civilizations with this ability will first try to build a "Dyson ring" - a ring structure surrounding the sun. They will first accumulate energy reserves and then implement iterative development.

A ring is equivalent to a "ring" on the sun. Later, when there were more rings, a Dyson sphere was formed.

Therefore, the "Dyson ring" can be said to be the primary form of the Dyson sphere.

Zhang Chun took a quick look and found that the huge star above them already had many "Dyson rings".But the project is far from halfway complete, as some of the rings are sparse and some are dense.The wave they just caught up with is relatively dense. Sometimes the Dyson ring blocks the sky and the earth becomes dim. Once the Dyson ring moves away, the star will be exposed to sunlight.

After Zhang Chun finished speaking, Hermione was stunned.

After all, what they were just aiming at was the "hell of ancient legends". Logically speaking, there should be things like volcanic eruptions, evil spirits, and demon lords. But the problem now is that the place they came to turned out to be a world surrounding this world. The super civilization-level project built by "The Sun"... the style of painting is super strange no matter how you say it.

Zhang Chun was actually even more confused.

He had already had a bold guess in his mind - these "devils" in Penello should be a "magic civilization". It was this magical civilization that expelled the "wizards", one of the aboriginal people - that is, now all over the earth. of "superpowers".And these superpowers have become ancient gods of various civilizations on earth.

At first, they still had contact with their original worlds, and some were able to return to their original worlds.But maybe after Zhuanxu's "Jedi Tiantong", the gods in the West declined rapidly, and the practitioners in the East could no longer "ascend".

They have no way to return to their original world, and in this world they have no choice but to enter reincarnation.

The so-called "superpowers" in today's world are just "temporary characters" in the reincarnation of these indigenous people of magical civilization.When they die, most will turn to reincarnation.

As for the "Eternals" like Bai Chenchen, they are lucky to have longevity and cultivation accumulation that ordinary people cannot match; but unfortunately, they are more aware of the depletion trend of the earth's "spiritual energy", but they cannot easily fall into reincarnation. , often after encountering an unexpected death, they really disappear.

The trend of death of "superpowers" has not changed. Reincarnation and "eternity" just have different ways of dying.

All of this could make sense.

Zhang Chun was even prepared to face a super scary "magic civilization".

As long as he could save Bai Chenchen, he was willing to take risks.

But when he actually arrived at "Hell", he was dumbfounded - this was not a "magical civilization", this was a "scientific civilization" that was far more advanced than human beings - the Dyson ring had even been created.

This kind of civilization should already be able to travel in space using light-speed spacecraft.

A "fantasy" campus novel of "Hogwarts School of Witchcraft and Wizardry" suddenly entered this advanced civilized world similar to "Trisolaris". The mismatch of the pictures and the huge gap made Zhang Chun find it extremely difficult to accept. .

The two of them watched speechlessly as the shadow of the Dyson ring in the sky began to fade (the central position of the Dyson ring that blocked the sun began to move away, and they were almost in the direct position of the sun again). They were speechless for a long time.

Instead, the wand ran out of Zhang Chun's arms with a bang. He looked around and showed a Σ(⊙▽⊙"a expression.

Hermione looked at the bones on the ground and asked Zhang Chun hesitantly, "This hell - ah no, is this world the place where Teacher Bai was taken away by the devil?"

"……probably."

"Why do I feel so awkward? According to you, this should be a super cosmic civilization. They...why do they want to rob Teacher Bai as a 'complete body of life'? This is equivalent to kidnapping the pilot on the aircraft carrier. Ants on an island are getting married...it's outrageous." Hermione looked confused.

"How did I know there were such big changes..." Zhang Chun also looked hopeless.

Although he was mentally prepared for the spoiler that "the world of wizards is related to highly developed alien civilizations" from Merlin's spaceship, when he really faced this, he felt that everything he knew was simply too absurd.

Just when the two people stared at each other,

The wand bone suddenly jumped up high, and an o(?Д?)っ expression appeared on its "face".

"What do you mean? Someone is coming?"

Zhang Chun looked at Gu Gu and didn't finish his words.I heard a "swish" sound next to my ear, and a white thing flew past my ear.

Hermione was startled and looked back.

A dozen or so black and unclear "people" appeared on the hill in the distance. Surprisingly, they even carried bows! !arrow! !

In fact, the white thing that just flew between them was also an arrow with white feathers.

Of course, judging from the flight of the feather arrows, these residents of "hell" were just warning, rather than really intending to harm them both.

Hermione looked up at the huge Dyson ring, and then at the "person" holding a longbow in the distance. She felt extremely inconsistent, and there was an expression on her face that felt that reality was ridiculous.

"You intruders...raise your hands and surrender! It was a warning just now, but you won't be so polite next time!" the "person" in the distance shouted to them.

The strange thing is that they both understand this language, as if this language does not need translation at all, it is something they understand naturally.

Zhang Chun looked at the person opposite, and suddenly a bunch of "data" came out in front of his eyes.

"What to do?" Hermione asked.

"Surrender!!" Zhang Chun looked at the "data" of those people, nodded, and whispered to Hermione, "There are weird things. Only by following them can we discover the real secrets of this world."

"Okay..." Hermione had no idea of ​​her own at this point and could only listen to Zhang Chun.

The two obediently raised their hands to express surrender.

A hazy person in the distance was hiding in the shadow of the Dyson ring. At this moment, he saw the two surrendering and then slowly walked over.

At this moment, the Dyson ring in the sky had flown away from here, and the red light diffused the world again. At this moment, the residents of the "Hell World" also revealed their true appearance...
