"Grandpa, when does it take for humans to break through the Kuiper belt?"

Facing the granddaughter's question, Lu Chuan felt a sense of embarrassment. The other party was indeed his granddaughter, but she was over 80 years old. Since she had not been reinforced, it would not be an exaggeration to say that she was an old lady.

The other party said that he was grandpa. If someone from outside heard it, it might attract criticism.

Lu Chuan still replied: "It is probably necessary for a level three civilization that humans can have enough technological power to break through this Kuiper belt, but they cannot come and go freely. Only after a level four civilization can they can they pass through normally."

After the third-level civilization, the existence of the energy shield can allow special spacecraft to fly over here, but it is definitely not a free navigation.

Countless planets and meteorites that hit us require several elements. The first is that the navigation speed is fast enough to dodge quickly. Second, a spacecraft is required to avoid it in milliseconds. Third, it has powerful energy to support the consumption of the energy shield when it is hit. Fourth, it has super attack power that can destroy the planets that hit the spacecraft when necessary.

If the four conditions can be met, you can basically pass through.

After reaching the fourth-level civilization, a new energy shield system has been released to ignore these planets. After the impact of meteorites, they can travel here freely. Compared with the current ships that destroy people, the spacecraft of the fourth-level civilization can completely treat these impacts as itchy.

Ye Lingwei and the others couldn't imagine what a level 3 civilization looked like, beyond their understanding.

Lu Chuan has also learned a lot, so he is extremely familiar with civilizations at all levels.

"Now, I will take you through, using physical means." Lu Chuan smiled. In fact, if you want to travel through time, you can do it with just one thought, but this is meaningless. Lu Chuan needs to let them experience more magical places in the universe and train their super strong hearts.

Ye Lingwei and the others were all ready. Even though they knew there would be no danger, they were still nervous.

Lu Chuan's arm shook, and cosmic energy suddenly appeared. In Lu Chuan's mind, it was like an invisible arm. Johnson and Johnson separated a huge crack on the Kuiper belt. Countless planets and meteorites were rejected by energy and separated to both sides.

This transparent bubble, with everyone, is moving forward here with an unprecedented thing.

"The width of the Kuiper belt, according to our current flight speed and the obstacles caused by its impact, may take 20,000 to 30,000 years to cross." Lu Chuan explained, which shocked Ye Lingwei and the others.

What does this mean in 20,000 to 30,000 years?

For the first time, Ye Lingwei and the others realized the terribleness of the universe with great clarity.

Countless planets and meteorites whizzed by the edges of bubbles, and the speed that passed in an instant. God knows what consequences will be brought by the impact?

Lu Chuan walked through here quickly with his family.

Occasionally, Lu Chuan became playful and controlled the bubbles, walking here, and was almost avoiding the whistling space meteorites, as if walking on a wire rope. The heartbeat of the play made everyone scream in surprise.

Compared to a roller coaster, the real excitement in front of you is called.

However, Lu Chuan didn't play for long. In his mind, he had already taken them to disappear in the Kuiper belt. By the time he appeared, he was already outside the Kuiper belt.

"Humans have always believed that after crossing the Kuiper belt, they will leave the solar system and enter the Milky Way. There is nothing wrong with understanding, but in fact it is wrong, because humans are like being imprisoned here by God and will never escape forever."

Lu Chuan's voice sounded low, because after leaving the Kuiper belt, it was not the endless starry sky that humans imagined, but... the endless white Olt clouds.

When it comes to Olt Cloud, many people don’t know what it is.

In fact, outside the Kuiper Belt, there is a more terrifying and vast area that humans may never be able to cross. This is the Olt Cloud.

The Ort Cloud is composed of trillions of spheres composed of ice bodies, which envelops the entire solar system in an all-round three-dimensional manner, which means that in the universe, no matter what direction you fly, you will eventually have to face it.

There is a principle to leave the solar system, that is, celestial bodies are no longer affected by the gravity of the sun.

The movement of small celestial bodies in the Ort cloud proves to be moved by the gravity of the sun. That is to say, it is the largest shell of the solar system, a celestial body protection zone composed of ice bodies.

Take Kuiper to the Alt Cloud, take the once famous Voyager II in North America for example. This distance takes three hundred years to fly to the Alt Cloud, and it takes about 30,000 years to pass through the Alt Cloud.

After hearing the cosmic knowledge that Lu Chuan told, Ye Lingwei and the others felt that their thinking could no longer be used.

"After the solar system, there is the Milky Way, not to mention all kinds of dangers here. The closest galaxy outside the Milky Way is also calculated in millions of light years. In this blank space, there is no celestial body, a complete vacuum zone. In these vacuum zones, there is no light, no everything... it is more like a land of nothingness."

The characteristic of the Ort Cloud is the endless ice celestial bodies, so the temperature here is so low that it makes people feel outrageously low.

"The next stop, I will take you to see the central galaxy of the Milky Way. Humans have always believed in places where alien life exists." Lu Chuan smiled. If he had no intention to move, he would never have been able to reach these places forever.

In one thought, Lu Chuan, Ye Lingwei and the others disappeared.

When it appeared, Lu Chuan appeared on the surface of an extremely huge desolate planet. This was once the place where Lu Chuan had been. It had the mark of Lu Chuan here and could arrive here in an instant.

Standing here, you can see a large number of various celestial bodies, which are so close that they seem to cause huge collisions if there is any fluctuation.

And among these huge celestial bodies, countless starlight spots can be seen.

But all of this is actually a false image. At the center, there are two super neutron stars. The light they emit is 200,000 times brighter than the sun, and it releases gamma rays at all times, creating a gamma ray storm, sweeping here.

"This is the central galaxy of the Milky Way. It is located at the rotational eye, so this is an almost static existence in the entire Milky Way. The celestial bodies here do not rotate or move, so they are so close that they don't have to worry about collisions."

"But there will be no life here, and it is even a forbidden zone for life. Have you seen the two celestial bodies that are so bright that they can't open their eyes? The light they release is not suitable for the birth of life."

Lu Chuan just briefly explained that after they got used to the environment here, they took them away again.

…………

Andromeda system.

This place is too far from humans, far beyond the calculating range.

Lu Chuan has been here several times, and naturally knows that there are alien races here. At this stop, Lu Chuan decided to take Ye Lingwei and the others to see even more shocking, alien races and alien civilizations.

"They can't see us, nor do they know we're looking at them."

Lu Chuan gave Ye Lingwei and the others a reassurance. After all, he suddenly came here from the Galaxy Center. Faced with a civilization that combines technology and magic, no one could accept all this immediately.

This is a semi-god race, with superb technology and incredible magical abilities.

For example, their life forms have actually been the form of energy since their birth. They have created technological civilizations, created robots similar to humans, and then put themselves into the robot's brain.

They are the brain, and the brain is them.

All kinds of robots have a ray of energy flashing on their heads, showing fluorescent green and different body structures, which means what the job they need to do.

If you want to change your job, you only need to change the robots. As long as they enter the robot's head, they can activate these robots and carry out work flexibly, etc.

In the universe, there is indeed everything, and the existence of life civilization is also beyond imagination.

"I call them Brain tribes because they are born with brains." Lu Chuan smiled and named other tribes, and traveling everywhere in this universe is definitely a necessary ability.

Don’t underestimate the brain tribe. The civilizations they developed have exceeded humans and should have reached the level of level 2.5 civilization. They do not have Dyson Ball, but in terms of energy utilization, they are even more than level 3 civilizations.

The brain civilization has the most similar technological path to humans, which is why Lu Chuan brought Ye Lingwei and the others here, at least it did not scare them.

Like a spectator, everyone has been observing all this with great enthusiasm, using human eyes, like looking at animals in zoos.

There seems to be no excessive proportion in this ratio, and they are indeed doing this kind of thing now.

Just above their heads, they observe their every move like a god, without even notice. This behavior, like voyeurism, can always bring some sense stimulation of satisfaction to people.

Lu Chuan held his arms, but did not disturb them, but took them to appear among the cities from time to time.

After they were all aesthetically exhausted, Lu Chuan said: "It seems that you should be hungry and tired again, so I just took this opportunity to make a news. The place you are going to this time is definitely beyond your imagination, and it can be regarded as the new residence I have chosen for you."

"Where is it?" Shi Ruoyu reacted the fastest. She was definitely a foodie. You can tell by looking at the food city she built on Mars. She almost used various methods to open a store in the food city.

Driven by madness, the food city on Mars has always been a holy place in the eyes of foodies.

Lu Chuan smiled and said, "You will know soon."

Seeing Lu Chuan keeping him in hiding, Ye Lingwei and the others were all aroused by curiosity and became expectant.

"You're ready, you close your eyes first, and open it when I say I can open it." Lu Chuan snapped his fingers, and everyone closed their eyes, as if they felt the movement, and then it was still again.

I had the feeling of moving my mind, and they knew that they must have arrived at their destination.

"You can open your eyes now."
