Pang Xuelin had never experienced curvature flight.

The worlds he had traversed, except for the magical stellar frog jumping technique of the Country Teacher World Carbon-based Alliance, the technical level of the other worlds basically did not go beyond the scope of particle physics, even the Dark Forest World was no exception.

But in the interstellar world, he actually experienced a speed of light flight driven by a curvature engine.

After entering the jasper-like bamboo knots that Shu Lao had prepared for himself, Pang Xuelin didn't feel any acceleration or vibration at all.

The bamboo seems to be in a static state all the time.

But when Pang Xuelin opened his eyes again, he found that he had left Planet 5 and was quietly suspended in space.

At this time, the inner wall of the bamboo and the green liquid have all disappeared.

Pang Xuelin's face was facing Kagantuya.

At a distance of 30 billion kilometers, the huge Kagantuya has condensed into a cluster of light, with Kagantuya as the center, and the starry sky is dotted with hundreds of stars, which are celestial bodies orbiting around Kagantuya.

Soon, the bamboo was activated, and all the stars in front of them gathered in the direction of the course, as if this half of the universe had become a big black bowl, and the stars were all sliding to the bottom of the bowl, and soon gathered into a dense mass in front of them, and it was no longer possible to distinguish the individual stars, they condensed into a cluster of light, like a huge sapphire emitting a brilliant blue light.

From time to time, scattered stars flew out of the light clusters, streaked through the pitch black space and flew back quickly, their colors changing from blue to green, then to yellow, and when it crossed the spaceship, it turned red. Behind the ship, the red giant star and the planets orbiting it coalesced into a red mass, like a bonfire burning at the end of the universe.

In the next second, this kind of sliding of the starry sky suddenly stopped, and Kagantuya was already close in his eyes.

Pang Xuelin knew that although he himself was the frame of reference, only a few minutes had passed.

But with the tree elder and the red giant star as the reference frame, twenty-eight hours have passed.

He crossed a distance of 30 billion kilometers to reach Kagantuya.

"Mr. Pang, you are now about fifty million kilometers away from Kagantuya's horizon interface, and if you don't do anything, you will fall into Kagantuya in the next month."

Pang Xuelin's ears sounded the voice of the old tree.

Pang Xuelin was a little surprised: "Old Shu, you can still keep communicating with me in real time from such a distance?" ”

Shu Lao said: "Mr. Pang, the bamboo you are riding on belongs to a part of my body, even if it is separated from the two ends of the universe, I can talk to you at any time." ”

Pang Xuelin was slightly stunned, with a thoughtful smile on his face, the reason why Shu Lao used bamboo to send himself over, in addition to his own request, did not mean to see what he wanted to do through the bamboo joint.

"Elder Tree, keep getting closer to Kagantuya, I'm going to cross the boundary of its horizon."

"Mr. Pang, are you sure?"

"I'm pretty sure."

Pang Xuelin said lightly.

He's betting, not only on high-dimensional humans, but also on the system.

According to Shu Lao's inference, high-dimensional humans have been able to freely travel on the hypermembrane, freely enter an arbitrary historical node, and open a fork in the long river of time and space at will.

This level of civilization has gone beyond the scope of ordinary civilization.

The technique is extreme, almost Tao.

And the system, in Pang Xuelin's view, at least surpasses the level of high-dimensional human beings and reaches another unimaginable height.

As an adventurer sent to this world by the system, Pang Xuelin didn't believe that high-dimensional humans were unaware of the abnormal state he was exhibiting.

After all, in the small attic of Cooper's house, he got the key parameters for the study of gravity.

Therefore, he was 80% sure that after entering Kagantuya, he would encounter a high-dimensional human.

As for whether he can convince these high-dimensional humans to help him return to the past and meet Chrissy again, it depends on how he communicates with them next.

Bamboo continued silently towards the horizon boundary of Kagantuya, and the relativistic effect of space-time distortion became more and more apparent.

Maybe Pang Xuelin only felt that a minute had passed, and the outside world had passed a whole year.

Pang Xuelin had no way back, he could only continue to move forward and run wildly towards the boundary of Kagantuya's horizon.

The horizon boundary is not a real physical boundary.

It is neither a membrane nor a surface.

It is simply defined as a specific distance to the singularity at which you cannot go out if you are below this threshold.

Within the reach of the singularity, where gravity is so great that nothing, not even light itself, can escape the clutches of a black hole.

If you're unfortunate enough to fall below this limit, then unfortunately, no matter how powerful your ship's power system is, you'll find yourself unable to escape from it, falling into deep darkness and eventually dying.

As the distance between Pang Xuelin and Kagan Tuya approached, ultra-high temperature particle streams and high-intensity cosmic rays began to appear around Pang Xuelin.

"Mr. Pang, I can only hold on for another minute, and after a minute, my bamboo will not be able to withstand the surrounding heat and the super gravitational pull of the black hole."

The old tree's voice was slightly alarmed.

Pang Xuelin said calmly: "You don't need to be strong, the bamboo will disintegrate." ”

Pang Xuelin didn't know how strong the bamboo was, but this bamboo was derived from the body of the tree elder, and there was no doubt that it was many times stronger than his own body.

Once the bamboo knot cannot isolate the strong gravitational tide of the outside world and the particle flow of the accretion disk up to hundreds of millions of degrees, Pang Xuelin's body will probably be torn apart into an atomic state in an instant, and then merged into the ultra-high temperature of the accretion disk.

At the same time, Pang Xuelin began to count down silently in his heart.

“60、59、58…… 10，9，8，7，6，5，4，3，2，1……”

The moment Pang Xuelin blurted out the last "1", the space outside suddenly turned upside down.

In the next second, Pang Xuelin appeared in a strange space with infinite depth.

"Hoo ......"

Pang Xuelin couldn't help but breathe a sigh of relief, in this operation just now, he did have the intention of gambling with high-dimensional humans.

Luckily, he won the bet.

What appeared in front of Pang Xuelin was a five-dimensional space with an infinite timeline that he had seen unfolding from Cooper's attic in the movie.

Beams of light from within the timeline shine through the gaps in the bookshelves in the attic and into this mysterious space.

Between the space and the bookshelf, there are strange vertical lines.

"This should be the real world, the string that physicists on Earth dream of......"

A flash of realization flashed in Pang Xuelin's eyes.

He went to great lengths to find Cooper, and in Cooper's attic he had obtained the gravitational parameters of the inside of the black hole.

At the time, he thought it was passed on to him by the future Cooper.

Unexpectedly, it was my future self who delivered this message.

"Mr. Pang, where is this?"

At this time, in Pang Xuelin's ears, the voice of the old man suddenly came.

As soon as Pang Xuelin turned around, he saw the jasper-like bamboo knot, silently suspended behind him.

Pang Xuelin didn't expect that the old tree's bamboo would follow him to this mysterious space.

Pang Xuelin smiled faintly and said, "This is the place I want to find, by the way, Elder Shu, help me check the string parameters in this space." ”

"Okay, wait a minute."

Soon, in Pang Xuelin's ears, there was a faint exclamation from the elder tree.

Pang Xuelin said: "Old Shu, what's wrong?" ”

Pang ...... Mr. Pang ......"

The old tree's voice was a little incoherent with excitement: "This ...... Where the hell is this, I seem to see the presence of membrane forces...... As long as...... As long as I stay here for a while, I will definitely be able to find the origin of the membrane power, and then I will be able to leave the small universe with my own strength. ”

Pang Xuelin smiled faintly and said: "This should be part of the supermembrane, I don't know what it is, by the way, give me the string force parameters." ”

"Oh...... Right now, right now! ”

Pang Xuelin followed the endless attic space and began to look for the scene when he and Cooper first met.

"This is? Edith? ”

Through the bookshelf in the attic space, Pang Xuelin saw a Cooper holding a cute little girl, sitting on a recliner, holding a book to teach her to read.

Pang Xuelin smiled faintly and began to follow the attic space and pull the timeline forward.

Half an hour later, Pang Xuelin finally saw the scene when he first met Cooper and entered the attic through the bookshelf.

"At the time, I was supposed to get the gravitational parameters from Cooper's watch on the shelf...... What about watches? Got it! ”

Soon, Pang Xuelin found a damaged watch on Cooper's bookshelf, and then he began to pluck the minute hand on the dial through the naked eyestrings.

Convert the gravitational parameters given to him by the tree elder into Morse code.

Time passed unconsciously, and after completing the transmission of gravitational parameters, Pang Xuelin breathed a sigh of relief and said, "Okay, my task has been completed, I hope to meet you, is it okay?" ”

In Pang Xuelin's eyes, the infinitely extended attic space began to converge rapidly.

In his ears, there was a faint voice of joy from the old man: "Mr. Pang, thank you, I have found the key point from the breakthrough of string force to membrane force, within 10,000 years, I can generate the origin of membrane force and leave the small universe on my own......"

Pang Xuelin smiled faintly and said, "You're welcome." ”

The next moment, a white light flashed.

Pang Xuelin couldn't help but cover it with his hand, and when he opened his eyes again, what appeared in front of him was a pure white space.

Whether it is front and back, up and down, left and right, it is all white.

But Pang Xuelin could feel the existence of gravity, and even felt his feet on the white ground, but he couldn't see his shadow, and he couldn't see the depths of the length, width and height of this space.

"Anyone?"

Pang Xuelin said loudly.

The sound traveled far away, and Pang Xuelin didn't hear any echo.

It wasn't until a minute later that a small black dot faintly appeared in the distance.

Subsequently, the black dot slowly grew larger, and five minutes later, the black dot had turned into a human being who was more than two meters tall, slender and slender, wearing dark silver tights, and had a strange appearance, appeared in front of Pang Xuelin.

His neck is very thin, his head is spindle-shaped, his eyes are slender, his mouth and nose are extremely small, there is no hair on his head, and he has a strange beauty all over his body.

"Hello, dear adventurer, welcome to our world, you can call me Heavenless."

"Heavenless?"

Pang Xuelin's eyes narrowed slightly, and he smiled: "Mr. Wutian, hello, do you know my origin?" ”

Wutian smiled slightly and said, "I guessed some, but I don't think that's the point of our conversation today, adventurer, you have done us a great favor, I am authorized to promise you a condition." ”

Pang Xuelin was slightly stunned, he originally wanted to see if he could get some side information of the system from the mouth of a high-dimensional human.

Unexpectedly, the other party was unwilling to talk to him about the system at all.

Pang Xuelin pondered for a moment and said, "Mr. Wutian, since this is the case, then I will say it bluntly, I hope to save my wife, who died of cancer in 2065 AD. ”

"Yes."

To Pang Xuelin's surprise, Wutian agreed in one bite, and then said: "I can send you back to 2038, the day your wife just gave birth." In addition, I will give you a small gift as a reward for you. ”

"A small gift?"

Pang Xuelin looked at Wutian in puzzlement.

Wutian smiled and said, "You'll know when the time comes." ”

Pang Xuelin nodded and said, "Then I can go now." ”

"Of course."

Wutian raised his hand and snapped his fingers lightly.

Pang Xuelin only felt that it was dark in front of him, and he didn't know anything.

……

Pang ...... Huge...... Wake up, Chrissy has a ......"

Pang Xuelin opened his eyes in a daze, and saw Cromwell Oliver leaning in front of him and waking himself up.

"What is this?"

Pang Xuelin found himself sitting in the corridor of a hospital.

In the next second, he was covered with a spirit, and his eyes widened and said, "Chrissy is born?" ”

Oliver smiled: "Yes, it's already born, it's a girl, you're going to be a father." ”

"I'm going to be a dad!"

Pang Xuelin's eyes flashed with surprise, and just as he was about to get up, he felt a heavy head on his shoulder.

As soon as Pang Xuelin turned his head, he saw eighteen-year-old Murphy leaning on his shoulder.

Pang Xuelin's eyes couldn't help flashing a trace of tenderness, and he pushed Murphy and said, "Murphy, wake up, wake up, your sister is going to give birth." ”

"Honey, don't make noise, I'm going to sleep a little longer......"

Murphy hugged Pang Xuelin's arm, closed his eyes and was unwilling to let go.

Pang Xuelin and Oliver looked at each other, and a hint of embarrassment flashed in their eyes.

Oliver stretched out his hand to Murphy's white forehead and said, "Dead girl, wake up, your sister is born!" ”

Murphy woke up from his dream all of a sudden, looked at Pang Xuelin in some confusion, turned his gaze to Oliver, and said dumbfounded: "Husband? …… Oh no, brother-in-law, this ...... What the hell is going on? ”

Pang Xuelin looked at Murphy with a smile, a hint of realization rose in his eyes, and said, "Murphy, it's 2038, and we're back." ”
