Hao Ren didn't know if the owner of the tentacle could hear his voice, but he really hoped that the eldest son could hold on a little longer—the planet was getting closer and closer to the tipping point, and the sun's gravitational pull and uneven heating process were tearing its crust off bit by bit, and even the strength of the eldest son's body could not resist this force. The Giant Turtle Rock Platform and the teammates brought by Hao Ren are powerless to reverse the fate of this planet, the time in the virtual world is running out, and now the only thing that can extend the life of the virtual world is probably only the persistence of the eldest son himself.

Since an hour ago, the shaking of the underground world has not stopped for a moment, the large and small shaking almost makes people feel like they are standing on a giant drum, and the explosion of rock formations collapsing from a certain direction from time to time is even more terrifying. There are signs that the planet is making great strides towards disintegration, and it is a constant reminder that they are following a 50 trillion ton boulder to the sun. But the people busy in the underground bunker had no time to care about it at the moment, and they were nervously tracking the nerve signals coming from the tentacles, and according to the analysis results from the ship's computer, they were going to the possible location of the brain nucleus.

Now that the team had left the hall where the alloy columns had been stored, the team was speeding through a spider-web-like underground structure. It is full of criss-crossing corridors and large and small cave dungeons, and the entire underground world is as complex as an endless labyrinth, if it were not for the ship's computer navigation, I am afraid that I would immediately get lost in those passages full of forks in the road. Hao Ren was at first surprised by the complexity of the place, and he felt that this structure was not very suitable for human habitation. But it soon dawned on him why the Underground Vault was designed this way: all the tunnels and caverns here were built along the tentacles of the eldest son.

Huge firstborn tentacles can be seen in all of the main passages, which stretch like the skeleton of the passages along the grooves in the ground or the recesses in the walls, and around them specially designed brackets and protections can be seen. At regular intervals, cables and pipes can be seen attached to the tentacles, apparently with the permission of the eldest son.

The entire underground shelter is a system of caverns built along the lines of the firstborn, so that the previous massive crypts seem to have an explanation:

They may have also been built with the help of the eldest son, as the planet's geology doesn't seem to lend itself to generating so many natural caverns.

As he went all the way deep into the shelter, Hao Ren's heart continued to pour out all kinds of emotions. The eldest son has always been associated with absolute destruction and ecocide in his mind, and all he sees is the destruction caused by the tentacles of the eldest son. Although he knew that this powerful creature was the shaper of the ecosystem and the original gardener, the image of the firstborn was still ingrained in his impression.

Here, however, Hao Ren sees a very different situation: the eldest son coexists in harmony with the mortal creation. There is every indication that the Drom must have lived with their eldest son from the beginning. They designed the shelter in a clever and just right way, and were able to build a complete set of equipment that was perfectly matched to the eldest son, which would have required years of tacit understanding and communication.

Hao Ren remembered what he had learned in his hometown of Yitzax: the eldest son could get along with the mortal race, and his nature was actually quite gentle.

At the time, he was still amazed by this information. And now the real example is finally in front of us.

After passing through a hallway containing four large tentacles. A near-perfect cavern appeared in front of everyone's eyes. The structure of this cave is very similar to the original "sacred cave" of Halletta, with a sunken ground in the center of the regular cavern, and a large mass of indescribable biological tissue lying quietly in the pit, and a large number of caverns can be seen around the cave, and tentacles extend from the rock wall to connect to the central biological tissue. At this time, the vibration of the underground world just eased down slightly, and Hao Ren heard a sound echoing in the cave: a powerful "pop" sound like a heartbeat.

"This is a large ganglion, and there is also a set of pump organs that maintain the circulation of body fluids," Hao Ren figured out the function of these biological tissues in front of him based on the research reports he had collected earlier. "We're pretty close to the nucleus. Set up some sensors here and you should be able to detect signals from the virtual world. ”

Lily immediately led a large group of autonomic machines forward. Place the sensor on the huge, indescribable lump of meat. She was a little nervous when she first started doing this work, but now she's completely familiar with it.

Hao Ren, on the other hand, observed other things in the cave: not only the tissues and organs that housed the eldest son, but also a large number of artificial equipment, as elsewhere. He saw that there were black ganglion around the large ganglia, and the cables on those ganglion were also attached to the tentacles of the eldest son, just like the small tentacles that were artificially made.

These machines are the first time they have been seen, and they don't seem to be quite the same as the ones that were used to keep the eldest son alive before. Hao Ren curiously stepped forward to check the status of the machine, but was surprised to find that the display of one of the devices actually emitted a faint light.

It's a miracle that there's one that works here.

"It seems to be a computer or something...... At least you can check the information," Hao Ren stepped forward and fiddled with it a few times, and found that the operation mode and system architecture of this thing were similar to those of Nolan's computer, "Huh? ”

Vivien walked over: "What did you find?" ”

"It's the record of the construction of the vault, and the bits and pieces of information about the virtual world project, and there aren't many things that can be read," Hao Ren retrieved the remaining logs, "...... It is recorded that the Vault was built to escape a catastrophe, and that the Zom and the Root of Origin worked together to build a strong fortress underground to fight the end of the world, and the Root of Origin here refers to the eldest son......"

Hao Ren said as he pointed out the key points in the information to Vivian, this ancient device is not very stable, and strange garbled characters appear on the screen from time to time, but it can still be used reluctantly: "These are the coded records of the virtual world, it seems that a large number of scientists and their eldest son have designed a simulation mechanism, this simulation mechanism can ensure that all human beings survive in a common dream for a long time, and survive until ......"

"How long will you survive?" Vivien asked.

"Survive to return to the real world," Hao Ren's voice suddenly became stern, "There is a plan for returning to the real world mentioned here!" They seem to be ready to wait for the outside disaster to end and return to the real world, and they also mention the Biosphere Recovery Program and the Body Rebuilding Program......"

Vivien exhaled, "It looks like something is wrong, the planet doesn't look like it can rebuild the biosphere anyway. Did you mention the specific circumstances of the disaster? Does it mean that the planets fall into the sun? ”

"Of course not, if they had known that the planet would fall into the sun, they wouldn't have had to expect to return to reality," Hao Ren shook his head, "The planet was derailed two or three thousand years ago, and the establishment of the shelter was ten thousand years ago, so the fall into the sun should have been an accident - probably this accident completely ruined the whole plan." ”

As he spoke, he looked up at the large ganglion in the center of the cave: "Probably this accident led to the beginning of the virtual world to appear towards the end of the script, so that it can roughly match the timeline in Nolan's memory: the trend of the world in her memory to the end of the world was also about two or three thousand years ago." ”

Vivien showed a slightly puzzled look, and then suddenly reacted: "You mean ......"

"It's having nightmares," Hao Ren said, pointing to the unspeakable mass of biological tissue, "and the whole world was swallowed up by nightmares." ”

Vivien's eyes widened in surprise, and at this moment, Nolan's anxious voice suddenly came from the communicator: "Hao Ren! Hao Ren! There's a situation on my side! ”

Hao Ren immediately connected: "What? The fire is burning again? ”

"No—I seem to have 'heard' the fabricator's voice again!"

"Fabricator", this is the name Nolan uses when he refers to the accuser behind the scenes of this world, and now Hao Ren knows that the so-called "fabricator" should be the consciousness of the eldest son, Nolan seems to have a special talent, and she can occasionally hear one or two dreams of the eldest son in the virtual world. Humans cannot understand the firstborn's thinking patterns, so the dreams she hears are usually blurred.

But this time things seem different.

"What did you hear?" Hao Ren asked hurriedly, he could hear the ominous meaning in Nolan's voice.

"I don't know if there's something wrong with my understanding, but I've heard that the world is going to perform 'euthanasia,' ......" Nolan's voice was filled with fear, "and that voice said it was going to hold back a qiē pain and let the world die without pain before some kind of collapse came." ”

Hao Ren took a deep breath.

The eldest son couldn't hold on. (To be continued......)
