The feeling between people is very subtle. If a very important person suddenly leaves the world, he will have telepathy.

Just as Li Kan and the mother of the insect stepped into the space passage and then the passage disappeared, Aunt Qin and Qingwu, who were far away in Lanxian Town, suddenly felt particularly irritable and were in a state of uneasy.

"Mom~" Huaer pulled Aunt Qin and said, "Why do I feel so sad? I want to cry so much? I suddenly miss Brother Li Dan so much."

Aunt Qin looked at Huaer and found that the little girl was already in tears.

Aunt Qin and Qing Wu looked at each other and saw what the other person was thinking.

After a while, Aunt Qin calmed down and helped Huaer wipe away her tears and said, "It's okay, you just miss him too much. When you grow up and become sensible, your brother will naturally come back."

"Really?" Huaer asked with anticipation.

"Yeah." Aunt Qin nodded heavily, but she knew very well in her heart. I'm afraid she would never see Li Kan again in this life.

Look at everything around them, it was given to them by Li Kan. Without Li Kan, they still had a hungry meal outside the city.

Without Li Kan, Qingwu probably has become a real ghost now.

Now their great benefactor has disappeared.

Aunt Qin thought Li Kan was dead, but Qing Wu felt that Li Kan would not die so easily. He should have gone to other places, far away from them.

After all, Qing Wu has been a ghost for a few days and has a much more knowledge than Aunt Qin.

"No matter where you are, young master, I will bless you here." Qing Wu prayed silently in her heart.

...

Besides, after Li Kan and the mother of the insect entered the space channel, even in a relatively stable stage, the tearing force of the space turbulence should not be underestimated. Li Kan only felt that countless hands were tearing his flesh from different directions with his nails.

Fortunately, this feeling did not last long. Some white silk threads flew out of the mother's hands, forming a huge cocoon around the two people, wrapping them inside.

But after being wrapped, the insect mother still did not stop, and there were still silk threads flying out of her hands, and the cocoon became thicker and bigger.

"Are you a silkworm?" Li Kan asked. After he was wrapped in a cocoon, he could not feel the tearing force of the space. Seeing that the insect mother kept "spouting silk", she couldn't help asking.

"What did you say?" The mother of insect didn't care what he said, and was determined to resist the power of space tearing.

"Uh... nothing." Li Kan smiled.

"Then shut up! There is so much nonsense to be said when riding a ride!" The mother of insects rarely made a furious move to Li Kan.

After hearing this, Li Kan stayed aside honestly.

The white cocoons bumped into the turbulent space like flies. Whenever they became smaller, the insect mother would supplement some white silk threads.

Li Kan didn't understand why, because the passage was ready-made when he came to the Demon Realm last time, and the space turbulence only went through for a moment, and his body felt a pain just now, and then he came to the Demon Realm.

The insect mother was worried because after the passage was opened, the two of them should have been sucked in, or the world that did not belong to them kicked them in, but they had to go in by themselves.

There are only two reasons for this situation, that is, they are not from the demon world, and that world cannot be kicked at will.

However, according to the overflowing demonic energy, it is definitely true that this passage leads to the demon world, so the insect mother dared to take Li Kan in.

I just don’t know why I drifted in this space channel for so long.

Since entering, I have had a meal, but I have never seen the slightest exit.

In fact, the space channel is similar to the wormhole.

In theory, wormholes are space tunnels connecting two distant space-time, just like vortexes in the sea, which are everywhere but fleeting. These space-time vortexes are caused by the rotation of astral bodies and the gravitational action. Just as vortexes can make local water surfaces closer to the bottom of the water, they can make two local spaces that are relatively far apart in an instant. However, some people imagine that a strange substance can keep the wormhole open, while others assume that if there is a strange substance called phantom matter, it has both positive energy and negative mass at the same time, so it can create a repulsive effect to prevent the wormhole from closing.

So far, scientists have not observed any evidence of the existence of wormholes. In order to distinguish them from other types of wormholes, the commonly known as "wormholes" should be called "space-time holes".

The "wormhole theory" is still a hypothesis, but scientific progress cannot be separated from bold assumptions. People once believed that the smallest component of matter was atoms, and later neutrons and protons were discovered. Similarly, humans have long believed that the universe is composed of matter, but the existence of dark matter overturned this conclusion. The significance of scientific assumption is to break free from existing constraints and promote human understanding of the universe and its own progress through continuous self-denial and doubt. As Sarucci said: "In any case, we need to ask ourselves, what is that?"

The concept of wormholes was originally born in the study of Schwarzsie's solution. When theoretical physicists analyzed the white hole solution, through an Albert Einstein's thought experiment, they found that the universe and space-time themselves may not be flat. If a star forms a black hole, then space-time is perpendicular to the original space-time in the Schwarzsie radius, that is, the place of the horizon. In an uneven space-time universe, this structure means a black hole.

The part within the horizon will be combined with another part of the universe, and a hole will be created there. This hole can be a black hole or a white hole. This curved horizon is called Schwarzsey's throat, which is a specific wormhole.

Ever since the discovery of the wormhole in Schwarzishi's solution, physicists have become interested in the properties of the wormhole.

The wormhole connects the black hole and the white hole, and is transmitted to the white hole through the black hole and radiated out of the white hole.

Wormholes can also appear in normal space and space in the universe and become a sudden appearance of super-time space. The wormholes introduced by the theory also have many characteristics, and will not be discussed here due to space limitations.

In short, we still have little understanding of the essence of black holes, white holes and wormholes. They are still mysterious things, and many issues still need further discussion. Astronomers have indirectly found black holes, but white holes and wormholes have not been really discovered. They are just a theoretical noun that often appears in science fiction works.

In the universe, the "cosmic term" is almost zero. The so-called cosmic term is also called "vacuum energy". In space without matter, energy also exists.

Inside it, this was introduced by Einstein. In the early days of the universe, the cosmic terms are necessary, and in the fundamental particle theory, it is also believed that the energy in the vacuum is naturally present. So, why does the cosmic terms of the universe become zero? Colman explained: In the early days of the universe before the explosion, wormholes connected many universes, and cleverly adjusted the size of the cosmic terms to zero. As a result, one universe may produce another universe, and there may be countless such subtle caves in the universe, which can lead to the past and future of a universe, or other universes.

Even if wormholes exist and are stable, it is very unpleasant to pass through them. The radiation that penetrates the wormhole will shift blue to a very high frequency. When you try to pass through the wormhole, you will be scorched by these X-rays and gamma rays. The appearance of the wormhole can almost be said to be at the same time as the black hole.

Perhaps these rays are equivalent to the tearing force in the space channel.

According to scientists, the universe is full of millions of "wormholes", but few have diameters exceeding 100,000 kilometers, and this width is the minimum requirement for spacecraft to sail safely. The discovery of "negative mass" has created new opportunities for the use of "wormholes", which can be used to expand and stabilize tiny "wormholes".

Scientists pointed out that if the "negative mass" is transmitted to the "wormhole", the "wormhole" is opened, and its structure is strengthened to make it stable, the spacecraft pass through.

However, the wormhole can only go back to the past. The so-called "instant movement" is actually to use the time difference between the two points of the wormhole. For example, point A is faster than point B; and the time of two points is water, and water will only flow from high to low; and because point A is faster, point A can go to point B through the wormhole. Because of the time difference in it, when reaching point B, people will feel that it does not take much time; at the same time, point B cannot reach point A through the wormhole, because of the exclusion of time - the time difference in the middle, causing a time fault. As for why point A has no fault when starting from point A - it is still because of the time difference. When starting from point A, time is point X; when reaching point B, the time at point B is just point X, and time can be completely connected. The only way to the slower time point to the faster time point can only be used to use the speed of light.

Using relativity without considering some quantum effects and any energy other than gravity, we have obtained some very simple and basic descriptions of wormholes. These descriptions are very important, but since our focus on black holes, not holes in the universe, I will only briefly introduce the properties of wormholes here, and for some related theories and descriptions of these theories, I will not cover them here.

What are the properties of wormholes? The most important one is described in the theory of relativity and used as a high-speed train in the universe. However, the second important property of wormholes, which is what quantum theory tells us, clearly tells us: wormholes cannot become high-speed trains in the universe. The existence of wormholes depends on a strange property and matter, and this strange property is negative energy. Only negative energy can maintain the existence of wormholes and keep the decomposition surface between wormholes and the external space-time and space-time continues to open. Of course, Dirac discovered that the choice of reference systems can help us to be more comfortable based on the Finkelstein reference system.

It is easy or difficult to analyze physical problems. Similarly, negative energy is very easy to achieve in another reference system of Dirac, because the manifestation of energy is related to the speed of the observed object. This conclusion also plays a very important role in membrane normative theory. Depending on the reference system, negative energy is very easy to achieve. When an object approaches the wormhole at a near-light speed, the energy around the wormhole will naturally become negative. Therefore, it can enter the wormhole at a speed close to the speed of light, and the speed is too high from the speed of light, so the object cannot enter the wormhole no matter what. This is one of the special properties of the wormhole.

Wormholes are a magical tunnel that can travel through time and space, making interstellar and even intergalactic travel no longer a dream. Scientists believe that wormholes are extremely unstable. If there is no strange substance with negative energy that keeps the hole open, the wormhole will suddenly close in an instant. However, according to research conducted by German and Greek physicists, wormholes can be opened without the help of this strange substance. This research discovery means that humans may find wormholes in space one day in the future. Perhaps, a civilization far more advanced than humans has already traveled between different galaxies with the help of the intergalactic subway system composed of wormholes.

Li Kan looked at the dense white silk, and on a whim he picked up one with a nine-ring knife and cut it lightly a few times. He found that the thread was extremely strong and it was not easy to separate it.

The insect mother felt his movements and asked, "What are you doing?"

"Let me try how hard this thread is." Li Kan said with a smile.

The mother of insect rolled her eyes and said, "You are sick. If you have a partition, I have to redesign it again. And if a beauty is around you, you are not interested, but you are going to test the hardness of the silk thread. Are you a man?"

"Uh?" Li Kan smiled unnaturally, and then said, "It seems that our relationship is not very good, you are not saying this well, right?"

"Oh? If I hadn't protected you, you would have been hacked to death by that guy. If I hadn't been to this world, you would have been in a different place, do you know?" said the mother of insects.

Then, the mother of insects asked for credit and told Li Kan about the situation when they first came to Qin.

As soon as they came to this world, they were chased and killed. At that time, Li Kan was unconscious and the mother of insects was seriously injured. She had no choice but to take Li Kan to escape everywhere.

While fleeing, Li Kan fell into a cliff. The insect mother thought he would die, so she left and found a place to recover from her injuries.

"So do you want me to be grateful to you?" Li Kan said. For some reason, he has always been pursuing the grace of a drop of water to repay him, but he is not very grateful to the insect mother.

He even thought with malicious intention that she had thrown her down from the cliff on purpose.

There is no way, who made the two of them be enemies before?

Li Kan's expression was clearly seen by the mother of insects. She said angrily: "Don't you believe me? Then what about now? Who took you back?"

Her words made Li Kan realize it suddenly. He said with great guilt: "I'm sorry."

Unexpectedly, Li Kan became cowardly so soon, and the mother of insects couldn't say anything.

Suddenly, the cocoon that had been unstable became peaceful.
