Ali took Chu Tianjiang and Nichol to another micro-universe.

"This is the third micro-universe I've created, and the third-to-last."

Chu Tianjiang was a little surprised, feeling that Ali was not telling the truth, because this was a very complex micro-universe, even more complex than the intruder's micro-universe.

The size of this micro-universe is almost 10,000 times that of the solar system, and hundreds of times larger than the micro-universe of the invaders!

In this microuniverse, there are exactly five stars.

It's just that that's not all. What made Chu Tianjiang feel even more surprised was that the center of this microcosm was not a star, but a huge natural black hole!

In other words, all five galaxies in this microcosm orbit a central black hole.

"I can only say that I am in a hurry and seriously inexperienced."

Chu Tianjiang looked at Ali with a puzzled expression.

"After creating the first two micro-universes, I felt that the more matter in the micro-universe, the better, so I stuffed a lot of matter into this micro-universe. Unfortunately, the basic laws of the three-dimensional universe are fundamentally different from the four-dimensional universe in which we live, and the more the better. In a very short period of time, about a million years or so by your standards, this microcosm has produced an extremely large star, about 100,000 times the size of the sun. The star only existed for a very short time before the Big Bang occurred. The five stars that you see today are actually the products of the Big Bang, when the material ejected by the main star formed more than a dozen stars. However, most of them were subsequently swallowed up by the black hole formed by the collapse of the remaining material of the main star. The five remaining stars are a little farther away, and they are slightly luckier. ”

"Intruders have been here?"

Ali nodded and said, "It was only after coming here that the invaders realized that I had created several micro-universes, and that there must be a first micro-universe created by me. ”

"And then think that all the mysteries can only be solved by finding the first microverse?"

Ali nodded again and said, "Anyway, it's all in the past. ”

"If you can't even figure out what happened in the past, how can you talk about the future?"

Ali sighed and said, "After creating this failed work, I created the fourth microverse, but I was too careful again. This micro-universe is relatively simple, and the environment formed cannot give birth to complex life forms, so it does not meet my basic requirements. After suffering four defeats in a row, I mastered the calculation of creating a micro-universe, and there was a micro-universe of invaders. ”

"Finding a balance?"

"You can say that, but it's not comprehensive." Ali smiled reluctantly and said, "This micro-universe is even bigger and has more resources, but it is not suitable for long-term habitation of intelligent civilizations. ”

"For what?"

"The central black hole is expanding all the time. Although it is no longer directly absorbing matter, it is still absorbing energy, and the escape radius of the black hole is expanding at a slow rate. In tens of millions of years, the other five stars will be sucked into the black hole, and the existence of an intelligent civilization is obviously more than tens of millions of years. ”

"Tens of millions of years is enough to do a lot of things." Nicol interjected.

Chu Tianjiang looked back at Nichol in surprise, but he immediately realized that it should be Rachel who had a direct personality who said this.

Of course, it doesn't matter, they're already alone.

"That's right, it's just that the scale of human beings is too small, and the skills they have mastered are not advanced enough." Ali smiled faintly, "Human beings are already the only intelligent civilization in the micro-universe I created, as long as they have enough strength, they can develop the resources in the micro-universe created by me at any time." ”

"These are all things in the future, and we have nothing to do with them."

Ali nodded, indicating that he understood what Chu Tianjiang meant, and said, "Let's go to the third star, where there are more than a dozen terrestrial planets, and one of the planets has a more suitable environment. ”

"What are you doing there?" Nicol asked again.

"There are a lot of things that I have to explain."

This time, the three of them did not fly over with great effort, but Ali directly opened up a subspace bridge.

In three-dimensional space, speed is limited, and the speed of light is the fastest speed. In this vast microcosmetic, it takes a long time to fly to any star. In order to break the speed limit, it is necessary to use space technology, and within the microuniverse it is a subspace bridge.

The star is slightly larger than the Sun, but younger, and at the peak of its life.

Around the star, there are a total of seventeen planets, and like the solar system, the inner circle is located on solid planets with smaller masses and similar to the Earth, while the massive gas giants are all in the outer circle, and one of the gas giants has reached about half the mass needed to become a star.

Arley chose the fifth planet.

This is a planet with a slightly larger mass than the Earth and liquid water, but the atmosphere is thinner and the strength of the geomagnetic field is weaker than that of the Earth, so the surface temperature is as high as 70 degrees Celsius during the day, and the ground temperature at night in the polar regions can be reduced to minus 120 degrees Celsius.

There are also land, oceans, lakes and rivers, and dense vegetation on the planet.

"The planet has a lifespan of less than a billion years, no intelligent life has evolved, and plants only left the ocean more than 100 million years ago, and all animals live in the ocean." Ali was patient. "Like plants on Earth, plants here absorb carbon dioxide from the atmosphere through photosynthesis, obtain carbon, and emit oxygen. As long as there is enough time, when the concentration of carbon dioxide in the atmosphere drops to a certain level, the atmospheric temperature will decrease, and then the ice sheets in the polar regions will expand, causing the global temperature to drop and the ocean area to shrink, forcing some marine organisms living in shallow sea areas to land and evolve into terrestrial organisms. Because the ocean does not occupy a large proportion of this planet, and the marine environment is very affected by the climate, it is very likely that the first intelligent life will appear on land, and the possibility of the birth of an intelligent marine civilization is not very large. ”

"You didn't bring us here for a scientific expedition, did you?" Nichole looked a little impatient.

Ali smiled reluctantly and said, "Of course not, just to introduce the environment here." ”

"The problem is, we're not sensitive to the environment."

"The battles that Chu Tianjiang will participate in are not fought in a vacuum, and there will be various battlefield environments, so there is nothing wrong with knowing more about the environment."

Nichol pursed his lips and didn't talk to Ali again.

"What's the point?" Chu Tianjiang was actually a little impatient.

"I've signed up for the family's internal tryouts, and when you're ready, we'll head to the arena where the battle will take place."

"Where?"

"The Silverhead Galaxy."

"What?"

"The first galaxy of the Milky Way, the equivalent of the capital of the Milky Way. There, we created a dedicated arena for fighting. ”

"This ......"

"Strictly speaking, it's a very special subspace."

Chu Tianjiang tightened his brows, looking even more confused.

"It's an extremely large subspace, equivalent to a micro-universe, and it's a very large micro-universe. In this subspace, a variety of environments can be created for participants to fight, and only the winner will be able to leave, and the loser will remain in the subspace. ”

"So, I can't afford to fail?"

"Not really."

"What does that mean?"

"If you fail, you can only wait until the day when the new order is established before you can return to the three-dimensional universe."

"How long will it take?"

"I don't know what to do."

"You don't know what to do!?"

"Establishing a new order is a long process, no one knows when it will be completed, and we all have an infinite lifespan, so time is not an issue for us at all. Besides, we haven't fully adapted to the environment in three-dimensional space. ”

"You ......"

"In the four-dimensional universe, time is not a definite concept."

Chu Tianjiang was completely speechless.

"How is the battle going?" Nicol changed the subject.

"Although our family is not very large, it is not small, and every family member is qualified to participate or send a substitute to participate in the battle. To put it bluntly, there must be a lot of participants, so it can only be done in batches, and the participants in each batch are determined according to the order in which they are registered. ”

"To put it bluntly."

"Each batch, with one thousand and twenty-four participants, fought one-on-one, and in the end only one participant came out victorious."

"What!?"

Chu Tianjiang squeezed Nichol's hand and said, "In other words, I have to participate in at least ten rounds of battles and win them all before I can become the final victor?" ”

Ali nodded, indicating that this was what he meant.

"Every time, it's one-on-one?" Nicol asked.

"The arena is huge enough to accommodate thousands of arenas, but the order in which family members sign up is not consistent, and there needs to be some space for spectators and judges."

"Audience?"

"This is the first major event after the dimension reduction, and all family members are very concerned about the final result, so there will be many people entering the subspace to watch the battle." Ali paused for a moment and then said, "Actually, this is also an effective way to ensure that the battle can be fought on a level playing field. ”

"Well, what else is there to pay attention to? Like, are there any rules? Chu Tianjiang sighed secretly, feeling that he had become a clown in the circus.

"Defeat the opponent within the prescribed limits."

"That's the only rule?"

Ali nodded, indicating that this was what he meant.
