The others camped on top of the shaft and kept in touch, while Hao Ren and Vivien entered the dark and deep ancient cavern.

The light from above soon left only a small bright spot, and there was no bottom in sight below. Vivien hugged Hao Ren's waist from behind and landed smoothly and quickly, while Hao Ren held a silver spear in one hand and a lamp in the other to light the way. He looked at the steel brackets and rails that were flying by quickly, and the sound of the wind when Vivien's bats flapped in his ears echoed: "Anyway, we haven't flown together for a long time." ”

"Yes, Cheng Tianjing followed you to strange places, either in space or in water, I almost forgot how to use the wings," Vivien's voice came from above, and she said as she adjusted the angle of her wings slightly, gliding in a spiral through the wide shaft, "I remember the first time you went to the sky with me, you seemed to be airsick?" Oh...... It can't be called motion sickness, so it's okay to stun me. ”

"Don't make a fuss, I was mainly startled at the time, you dragged me to the sky without saying a word, how can ordinary people pass through this." Hao Ren moved slightly as he spoke, the soft touch from behind him made it a little difficult for him to concentrate, Vivian immediately noticed this, and grinned: "Why, we have flown together so many times, I don't feel used to it." ”

Hao Ren pouted: "No matter what, you are also a beautiful girl, okay?" ”

“…… I don't really think about this, you know I usually have a hard time filling my stomach," Vivien blinked, and suddenly saw a faint light in front of her, "Landlord." It seems like the end of the road ahead! ”

Moments later, the two landed lightly on a circular alloy platform. The platform is enclosed along the walls of the shaft around it. In the center was a hollow with a radius of several meters, and a dark red light was coming from beneath the hole. Hao Ren leaned over and leaned on the railing to take a look. I was shocked to find that there was blazing magma underneath.

"It can't be the center of the earth...... Vivien also looked over, her eyes widening in shock, "We're so deep?" ”

"It doesn't have to be the center of the earth, but it should be very close," Hao Ren looked at the slowly surging faint red light, the internal energy of this planet has declined, and the magma lake near the core of the earth also looks a little weak, but that magma lake still makes the scene at the bottom of this shaft like hell, if it weren't for some kind of thermal insulation technology still in effect. I'm afraid the entire metal platform will melt down, "and that's supposed to be the source of energy for the whole system." Heat exchange between the Earth's core and the Earth's surface...... It's a huge project. ”

"Those old guys on Earth should really come here to see it......," Vivien sighed, "Anyway, why do I feel light-footed?" ”

Hao Ren took a few steps in place: "Gravity has weakened. We've come to the deepest part of the system, where gravity is about one-fifth of the Earth's surface. Look for it, there should be an entrance near here, and the number of jù terminals scans out that there is a hollow structure similar to the center of the control zhì. ”

Vivien raised her hand and pointed to the opposite side of the circular platform, "You mean that?" ”

Hao Ren looked up and saw a heavy, metallic gate standing silently opposite the platform, with a faint light flickering next to the gate, as if to prove that the system behind the gate was still alive.

The two of them came to the gate. Hao Ren looked at the flickering light control panels next to the door, and he exhaled: "We have arrived here, which is enough to prove sincerity." Do you still have to close your doors at this time? ”

It seemed that no one on the planet should have responded to his words, but the floodgates were still moving. In a burst of "snort" with the airlock deflating, the circular gate first retreated, and then Kerala rolled to the side. Hao Ren and Vivien stepped into it.

They walked through a long safe passage. Eventually arrive at a rotunda.

A massive, pipe-covered cylindrical device is placed in the center of the hall, which extends to a dome more than a dozen meters high. A faint streamer of light flows through its outer pipeline. Countless thick cables extended from the base of the cylindrical installation, spreading out like vines across the floor of the hall. A circle of machines connected to the hall is in the air. There are no formal lights in the hall, and it is entirely the light emitted by the machines themselves that provide the lighting, allowing people to see the figures of these ancient devices in the shadowy light and shadow. A low, compound hum echoed around it, like an inorganic breath.

Hao Ren looked at the cylindrical device in front of him, this should be the main engine of the Ark. He could feel that this was the heart of the entire planet, and that countless things—abstract and invisible—spread from here to the entire planet outside. He took a deep breath: "I'm here, won't you speak?" ”

They were silent for a few seconds, and a low, emotionless synthesized voice sounded from the depths of the cylindrical installation: "My mission is to manage the ark and bring the creators safely to a new home." I was made, they gave me thought, they gave me logic, they gave me purpose...... The meaning of the existence of the whole system is to make the civilization on this planet survive. That's the only thing I know and the only thing I should do. ”

Hao Ren looked at the host, as if looking at a living person: "What the hell is going on here?" ”

"Before the Ark set sail, civilization was extinct."

A screen on the wall of the hall flickered brightly, and a crystal clear, aqua blue planet glittering in space appeared on the screen. Immediately after that, the sun in the corner of the picture exploded, and the strong solar material blew across the surface of the planet, but under the effect of some powerful shield, the planet seemed to survive intact - but after successfully resisting the solar eruption, something abnormal happened on the surface of the planet, Hao Ren did not see the essence of the disaster, only saw that the lights on the entire planet decreased and extinguished at a speed visible to the naked eye, and then fell completely silent.

Time passed, the sun cooled, the planets froze, and a pale blanket the planet's surface, and the whole world was lifeless, and the artificial lights never came on since.

Vivien turned to look at the host, "Who did that?" ”

"An indescribable creature, the creators call it a natural disaster," the synthesized sound of the Ark's main engine sounded again, and the screen flashed, and a huge strange thing appeared in the center of the screen, as if countless tentacles, roots, plants, and pieces of flesh were mixed together, its strangeness was indescribable, only a sense of horror that seemed to evoke the instinct of the creature permeated from those twisting roots, "It destroyed the civilization on the Ark after death." ”

Sure enough, it was the eldest son who appeared on the screen, but Hao Ren was shocked after hearing the words of the Ark host: "After death? You killed it? ”

"It burst out of the surface from deep underground, but the creators, with the help of the Starmen, managed to separate the creature from the planet and push it into the Sun, which was then detonated by the Starmen. The flesh of this creature. The body was wiped out in the stellar flames, and yet ...... There is something incomprehensible left on the planet. It ended up destroying an entire civilization. ”

"Something incomprehensible?" Hao Ren felt a little confused, until Vivian next to him whispered a reminder: "Something similar happened in Tanagus. ”

Hao Ren suddenly said: "Is it the soul of the eldest son?!" ”

The main host of the Ark was silent, as if it couldn't understand what "soul" meant, and Hao Ren had already guessed what the truth was back then:

Although the natives of this planet are not superior to the other second sons in terms of technology, with the help of the "people of the stars", they have indeed achieved a feat that no other second son has achieved: they have succeeded in destroying the flesh of the firstborn at the cost of their own sun. Body. However, this feat did not save the fate of their entire civilization - the firstborn in the flesh. After the body died, he still killed everyone on this planet with his soul!

However, this soul should have dissipated, and the Giant Turtle Rock's induction radar did not scan the signal remnants of the eldest son on the planet. It is precisely because it has dissipated that no evidence has been found that the eldest son has survived.

Hao Ren figured out the joints, sighed slightly, and then looked at the main engine of the ark sternly: "Who are the people of the starry sky?" (To be continued......)
