Nina has made a breakthrough in the study of mysterious holes, or after human beings have a preliminary understanding of the civilization egg, she put forward a new cosmic membrane theory by analyzing the reflected wave frequency of the civilization egg, and then comparing the data of the mysterious hole, we still do not know the cause of the mysterious hole, but the result is completely opposite to what we speculated, the surface of the mysterious hole is not more loose than the cosmic film, but more dense, and it itself is a cosmic film with a more complex structure.

It's too strong for us, it's like the Bronze Age humans have discovered a gateway to the universe, it's very valuable for civilization, but we can't use it, maybe it's luck or maybe it's a hidden arrangement, Nina found a way to enter the mysterious void, we managed to release multiple probes into it, and then successfully recovered, these little machines collected a lot of precious research materials.

However, Nina's enthusiasm for the mysterious space is increasing day by day, and she finally insisted on starting the manned plan in advance, and drove a special exploration spacecraft into the mysterious hole, but the experiment has been very smooth before, but this time there was a problem, the gravitational guide cable connected to the spacecraft suddenly lost control, and broke in the process of recovering the spacecraft, we immediately launched a follow-up rescue work, but we found the traces of her and the special spaceship, and the mysterious space looked small from the outside, But the space inside seems to be layered, and once you enter, you will see a huge space that is constantly expanding, and we can't find her by all means, so we can only announce that we will give up......

The exploration plan of the mysterious void was terminated again, such monuments can be seen in many places, many people believe that she is not dead, but lost in that space, if one day our technology leaps forward, we can explore the mysterious hole again, maybe we can find her back, but thirty years have passed, there is no progress, and the mysterious hole has been closed to this day, even if she is still alive...... The ship's supplies should have run out of supplies.

"......" Mark quietly listened to Sun Tan's narration and sat under the statue without saying a word.

"That's the way it is, I've told you everything I know."

"Perhaps, today?" Mark said as if talking to himself.

"What?"

"The cause of the emergence of the mysterious void is that our cosmic membrane is affected by the eggs of civilization...... Maybe we'll know the truth today. Mark said.

"But...... It's been all these years. Sun Tan tried to persuade him to let go of the matter, but Mark obviously didn't listen, and became even more excited.

"The cosmic membrane will isolate the rules of physics, and the flow of time in the civilization egg is completely different from ours, maybe she is still alive."

"Even so, as a creature of this world, it is even more impossible for her to survive for a long time under another set of physical rules." Of course, Sun Tan knows best, the group of small civilization creatures in his hands have taken root in this universe, and others don't know that the scientific and technological achievements of human beings today are indispensable to their efforts, and the IoT world printers that every household has today are researched by them, and some of the core components are unbelievably small, and the machine tools that process them are all made by those small civilization creatures...... When those little guys came to this universe, what a price did they pay to survive, technology is as strong as them, and they also paid the price of 99% of the population to succeed.

"Since it's a rule we don't know at all, who will know until the day the secret is revealed?" Mark was full of confidence from nowhere.

In fact, the source of this confidence is only known to him, that is, the illusion he saw that day, he saw a figure similar to Nina through the mysterious and empty power, this must not be a coincidence, all this may have been predestined a long time ago, he did not believe in fate before, but after all this, Mark believes that fate can also be explained by science on a higher level, in a higher dimension, every second of our world flows like a bead on a chain, interlocking, from the origin to the end……

"Let's go, it's almost time, it's time to go." Mark stood up from the foot of the statue, Nina's sculpture was very expressive, still so heroic, with a confident smile on her face, she was a pioneer of her time, she paid for herself, left a clue for everyone, and followed this thread...... The task of continuing to unearth the truth is again in the hands of Mark.

Sun Tan and his entourage set off again, going to the salvage platform deeper underground, there were still two hours before the civilization egg was pushed away from the center of the earth, and the salvage department that received the civilization egg launched ten small exploration planes to the lower level, they are responsible for stabilizing the trajectory of the civilization egg, and if it falls off at a critical moment, they still have a chance to rescue it again, so as not to let the civilization egg fall into the depths of the earth again.

Everyone was nervous, and when Mark entered the salvage platform, no one else noticed him, they actually knew Mark, and Mark was also a person who had left a strong mark on the scroll of the times, and was once idolized by people, and during the Earth-Moon War, conservatives even wanted to resurrect Mark in advance as a war bargaining chip, but fortunately, Sun Tan tried his best to stop it, and this plan did not succeed in the end, which can also be seen that Mark's influence did not decrease even after he hibernated, but became bigger. It's just that at such a critical juncture, no one can distract from receiving him, and all the staff are engrossed, as if they are launching the first rocket of mankind.

Rocket launches are now a piece of cake, and are even about to be obsolete, and this time what they have to do is no longer to go into space, but to reach out to the ground...... This time, the light that illuminates the future of humanity is not the starlight from the void, but the endless fire that burns underground.

"Five thousand meters!" One of the operators shouted, everyone was ready, and the ten probes that had just been lowered began to pick up the eggs.

A small universe, held in the hands of human beings, this feeling is really amazing, Mark feels a strong sense of excitement in his heart, there is no screen in the operation hall, only some monotonous numbers will pop up on the detector, telling people the distance of the probe, the stability of the situation and the speed of propulsion, but even so, Mark can still imagine that scene, he is wearing a thick isolation gown, little by little to the edge of the front of the salvage platform, outside the layer of nano insulating glass, is a super deep well that leads to the center of the earth.

"Four thousand meters!"
