Hilde walked to the center of the hall, pointed to a 'white light cluster' in the center of the galaxy's projection, which was only about ten centimeters, and said proudly: "Next, let me introduce my home planet, the Aslant Galaxy.

This is our sun, which we call 'Hironus', which means the kingdom of heaven, the kingdom of the gods, the kingdom of eternity.

In your units, it has a diameter of about 8,740 kilometers and a surface temperature of 9,117 degrees Celsius.

She is a white dwarf star with a temperature drop of 3.6 degrees Celsius per 10 million years. In its natural state, it can also provide protection for our civilization for at least 1.2 billion years. ”

"There are generally four types of galaxies in the universe that are best suited to carbon-based life: red dwarfs, yellow dwarfs, white dwarfs, and a few blue dwarfs. These are all single star systems.

Among them, red dwarfs have the lowest probability. Because red dwarf galaxies are too small, there is too little matter in the galaxy. But for later interstellar migration, the red dwarf galaxy is a good choice.

This is followed by a blue dwarf. Blue dwarfs are rich in material, but blue dwarfs are less stable and have strong radiation, and there are more magnetic storms and stellar storms.

Yellow dwarfs again. Yellow dwarfs are relatively large, have relatively stable combustion, and are relatively rich in matter in galaxies. For example, your solar system.

But the highest probability is the white dwarf. Most white dwarfs are the second stage of the life cycle of yellow or blue dwarfs. Presents a degenerate structure.

White dwarfs no longer engage in nuclear fusion, or only a little nuclear fusion, and are stable and emit less harmful radiation.

White dwarfs can live for hundreds, if not hundreds of billions of years. The time period suitable for the birth of life is generally 30 to 20 billion years. After that, the temperature will gradually cool down and it will no longer be suitable for life.

However, white dwarfs can continue to heat and glow by adding fuel in the later stage.

Industrial waste, construction waste, household waste, interstellar gas, comets, asteroids, etc., can all be used as fuel for white dwarfs.

The atoms of these substances are crushed by the gravitational pull on the white dwarf star and release energy.

As far as is known, almost all advanced civilizations have adopted white dwarfs in their capital systems. ”

Zhao Yiyi nodded slowly.

Heard continued: "Our galaxy was once a blue dwarf, so it is rich in matter, with a total of 11 planets.

The first is the star 'Grevesi', which should be interpreted literally as 'the entrance to heaven after death'. Because it often appears in the western sky of our home star, it reflects the light of the stars at sunset.

Grevesi, is a rocky planet that is tidally locked by gravity.

The second is the planet that gave birth to our life, which we call 'Aslanth', which literally translates to 'the rich earth'. It is about 86 million kilometers away from the star. The diameter is about 14,000 kilometers, and the surface gravity is about 10.6.

White dwarfs have a higher surface temperature than your Sun, but because white dwarfs are so small that they scatter light so much that living planets need to get closer together to get enough light and heat.

The third is the 'Simit' star, which literally translates to 'Goddess of Harvest'. Every autumn harvest, it will appear above our heads.

Located about 122 million kilometers from the star, Simit is almost the same size as Aslant and has similar conditions, just at a slightly cooler temperature.

Now, Simit Star has become our second home.

We regulate the temperature by releasing greenhouse gases, increasing the thickness of the atmosphere, and building space-concentrating facilities.

My family's fiefdom is on the planet Simit.

The fourth one is......

The focus is on the sixth planet, Salmi. The literal translation should be interpreted as 'God King'. It's more striking than our stars.

From our home planet, Aslant Star, it presents a more striking golden yellow, noble and gorgeous.

Salmi is a large gaseous planet with a diameter of up to 160,000 kilometers and large rings.

It has three large satellites, which are:

Sawei 1, about 5,600 km in diameter;

Sawei 2, about 4,700 km in diameter;

Save-3, with a diameter of about 3,500 km.

We're going to Savo 3, which is covered with snow and ice and has a surface temperature of about -176 degrees Celsius. ”

Heard clicks on 'Savit 3', and Savit 3 zooms in to show the details.

"In the past, we used to think of Safe-3 as an ordinary satellite. It wasn't until I accidentally got a key that I realized that Sylo 3 was actually an artificial planet, a 'space-time temple' made in ancient times.

It is said that in ancient times, the camp of order and the camp of chaos broke out very fiercely, and more than once; During the conflict, some space-time temples lost contact and became interstellar wandering planets, nowhere to be found. That's one of them. ”

Zhao Yiyi listened very carefully. Hearing this, he immediately asked: "Since you lost contact since ancient times, how did you find it?" ”

"Quite simply, I found a key.

Generally, there are eight high-level players in the Time and Space Temple, each of whom controls eight keys. All eight high-level players were killed in battle, and the key was lost, causing the Temporal Temple to lose contact.

However, as long as you find any of these keys, you can sense the corresponding space-time temple within a certain distance.

When I found out that the Temporal Temple was actually on my doorstep, I was shocked. ”

As he spoke, Heard pulled out a small, pink 'bell'. The bells are delicate and cute, jingling. It looks like a little girl's headdress.

Almost at the same time, a few lines of pale red font appeared in front of Zhao Yiyi's eyes:

Temporary Mission: Become an Immortal.

Mission Description: Discover special items that contain a lot of energy......

Zhao Yi directly ignored it. I'm going to really grab it, but I can really fly up in the day and go west.

After a few shakes, Heard added, "The keys have different shapes. I found it on the free market, and the seller said that it had the effect of clearing the heart and removing dryness, and I wanted to buy it for my daughter to play.

After returning home, he had a connection with Sawei 3, and this was the only time he discovered the problem. ”

Zhao Yiyi became interested: "Since you are at the door of your home, why don't you open it yourself?" Such a space-time temple should be very precious! Even in antiquity. ”

"Because it takes at least five keys to open the Temple of Time and Space. To fully activate and control the mission lobby, you'll need eight keys! ”

"And how did you find the rest of the keys?"

"You're smart and have the potential to be a space-time player." Hilde looked at Zhao Yiyi appreciatively, "Any key can be activated by certain means to sense the rest of the keys." Of course, there is a limit to the sensing distance.

All five of us met in the search for the key.

We fight back-to-back, we work side by side to improve.

We have waded through death, defeated evil, and become a third-level player. ”

Speaking of this, Hilde's face was once again filled with a faint haze, and his high-pitched voice began to be low, "I don't want Adou to have a problem at this time." Our friendship has been around for more than 300 years. ”

"Three hundred years? I think Adou is in his eighties! Zhao Yiyi was surprised again.

Hilde nodded slightly: "The time of the mission of the Time and Space Temple is different from the time of reality. You need to find out for yourself. Different missions, different civilizations, etc., will cause different time flow rates. ”

"Will such a mission have an impact on your civilization?"

"Yes and no!" Heard calmed down, "During the mission, it was carried out in a 'mirror space', like a mirage space, or quantum space, or parallel space.

In short, it's hard for me to explain.

Adou said, there is a study in your world that is similar to this phenomenon, called 'Schrödinger's cat'. ”

Zhao Yiyi: ......

Heard continued: "If we had done it perfectly, it wouldn't have any impact on the real space.

But if we are defeated by the players of the chaotic camp, the impact may affect the real space little by little in the next few days, or even decades.

For example, if a player from the chaotic camp destroys our civilization in the mirror space, then after the mission is over, our civilization will definitely disappear, and there is no means to stop it. It's like ...... Destiny. ”

Zhao Yiyi really understood: time and space players are not playing online games, maybe one accidentally not only has to finish the game himself, but also has to catch up with his own civilization!!

This was a heavy topic, and Zhao decided to change the subject. "Then again, this space-time temple in the ancient era should be very ancient, can it still be used?"

"There shouldn't be a problem. The Sanctuary of Time and Space has technology beyond our imagination. It doesn't matter if it's really broken, as long as you submit the task, you can still get a great reward. ”

Zhao Yiyi asked again: "What about Adou's key, did he take it away?" ”

"Nope! If he takes the keys, how can we allow him to leave. Hilde said, pulling out a jade pendant, which was the same one that Hilde had snatched from the wall when he had just rushed into the room.

This is just a very ordinary jade pendant, which looks average in color, and has a simple relief of a lotus flower on it.

Zhao Yiyi didn't answer, just looked at it, and continued to ask: "You just said that we may encounter players from the chaotic camp this time. What's going on here? ”

Hilde's face was solemn again: "In the process of doing tasks and obtaining keys, we were discovered by players in the chaotic camp, and they robbed us of three keys.

Just hope that all goes well, and before the players from the chaos camp arrived, we got the job done. ”

Zhao Yiyi frowned slightly: "But Adou left, and he walked very simply." He must have gotten some news! ”

Hilde's face was gloomy again, and he didn't speak.

Zhao Yiyi took a deep breath and asked cautiously, "What can I do?" ”
