The space folding technology is very interesting, this kind of magical technology that allows spacecraft to span dozens of light-years in an instant, in fact, it is a kind of four-dimensional magic. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo//

If space is a thin sheet of paper, and the distance between a point and point b is ten light-years, then even if your spacecraft is infinitely close to the speed of light, it will take you ten years to complete a one-way journey.

Ten light-years is really nothing for the universe, and the distance between two terrestrial planets is hundreds of light-years, which is obviously an unbridgeable gap for human lifespan, even if there is a very advanced hibernation technology, but this technology is generally unwilling to be used by countries.

Because hibernation technology can bring very serious ethical problems and destroy the fragile moral system of society, imagine what it would be like for an old man who was dying to suddenly see his father who left him 50 years ago and walked to him with a young 20-year-old body.

Once this hibernation technique is spread, there will even be a terrible scene of grandparents and grandchildren having indecent love, so hibernation technology is only used in the early days of human exploration of the universe, and most of them are suitable for one-way no-return travel.

It wasn't until the advent of space folding technology that humans had the technological basis to truly explore the universe.

How can I teleport from point to point B? In fact, as long as you can think about the problem in a four-dimensional space, you can find the answer, you can bend the piece of paper, so that the dots and dots bend together, until the last two dots are close together, and then you use a sharp pencil to skewer hard.

Well, the movement that pierces the two points is the entrance to the folding space, and the spacecraft is from this puncture point for tens of light years to travel long distances, when the spacecraft completes the crossing, the three-dimensional space will have a strong self-repair ability, the pierced hole will be repaired quickly, and the paper will slowly return to its original appearance under the action of elasticity.

Maybe it's a bit inaccurate to describe this concept as a piece of paper, because paper is also a two-dimensional plane, so you can think of it as a piece of soft seaweed mud in a cuboid, which can be bent and folded as well.

Even if you have a heavy steel plate in your hand, as long as the force is strong enough, it will fold and bend like paper, and eventually the two points that you want to overlap will come together.

The long-term energy storage of the space folding engine is actually a process of folding three-dimensional space, and the water ripple mirror space that appears at the end is the hole pierced by a sharp pencil.

Li Mi really knows the difference between the three-dimensional world and the four-dimensional world today, because the hard-working Li Mi has fallen into the thinking space and can't extricate himself.

Li Mi already had a fantasy in his mind, and Professor Truss patiently explained everything in front of him like a child: "When the three-dimensional space is bent and folded like a piece of paper, when the two coordinate points are close together, don't you find that there will be a circular space under the two points?" Wherever is the time-warped four-dimensional space, the secret is hidden there......"

"Your body has just been pierced by the timeline, and the time magic cast by the summoning circle is essentially using the power of time in the four-dimensional space, which is the same principle as the space folding engine......"

"It's just that human beings use machines, while magicians use their own spiritual power, and the same principle has different carriers, naturally creating two completely different strange worlds......

"We people in the secular world can perform space folding from a distance, while magicians can play this wonderful time magic!"

"Enough!" Li Mi suddenly shouted, "You tell me, how should I get out, what should I do now......"

But Truss is just a fantasy in Li Mi's mental consciousness, and he is not really solving his doubts, and the professor is still nagging to popularize basic spatial dimension knowledge.

But in any case, Li Mi finally figured out the dilemma he was facing, it turned out that at the moment when the person in the suit cast time magic to trap Li Mi, when the magic circle had opened a small folding space, and the magic was about to make the time around Li Mi pass rapidly, the Half Moon suddenly fired.

Tens of millions of tons of N-equivalent light energy naval guns just hit the mountain where the magic circle was located, although there was a distance of more than 4,000 meters in between, but the violent energy flow still spread in the mountain in an instant.

At that time, the person in the set had already completed the cast, and the timeline penetrated Li Mi, and the time around the timeline had begun to accelerate, and at that moment a very small time hole had been formed.

According to the normal procedure of magic, Li Mi will be stolen time in this ultra-small time hole, obviously only a second has passed outside, but he has already spent an hour in the timeline.

Accelerated aging is actually a very clever time trick, but the power should not be underestimated.

The bombardment of the Half Moon's main artillery was as if a huge force had been exerted on the heads of Li Mi and the people in the suit out of thin air, just like the spaceship was being pushed hard at the moment when the spaceship was folding the space.

As long as your strength is strong enough and the angle is precise enough, then it is possible for you to push the spaceship into the four-dimensional space, which is what the professor said, the circular space formed by the two points close together, that is, the pocket.

Now Li Mi and the person in the set were pushed hard by this force, the force was strong enough, and the angle was also very accurate, and the two of them fell into the four-dimensional space at once.

Li Mi didn't know if they were the first people in the universe to travel to the four-dimensional space, but he knew very well that no one in this universe had ever said that he had traveled to the four-dimensional space, which means that the four-dimensional space was difficult to enter and it was equally difficult to get out, and it was very likely that the two of them would be trapped in this place forever.

The person in the suit seemed to be sleeping, maybe unconscious, Li Mi touched his pulse and found that he was still breathing, and then Li Mi was surprised to find that there was air in the four-dimensional space, and people could breathe here.

Surrounded by the void, Li Mi could move freely as long as he gently manipulated the miniature engine of the battle armor, and around them were layers of windows, which could not be seen at a glance, forming a ring around them.

Before exploring, solve the troubles, Li Mi's armor has always stored some equipment for survival in the wild, including high-strength mountaineering ropes, not to mention the first to tie up the people in the set, the bundle is the same as zongzi, and then one end of the rope is tied to his waist.

Now, the adventure of the four-dimensional world begins!
