Between the steel passages, a faint blue light flickered, and a clear and heavy stampede could be heard in the flow of magic.

At this time, Joshua and the others were heading deeper into the pyramid under the guidance of No. 3, and their goal was the [Ecological Cycle Zone] below the central area.

After a little conversation with Moria and the others, Joshua decided to believe what No. 3 said - after all, no matter how suspicious she was, she did not show any malice from the beginning, and as the only existence they met in this world that could communicate, Joshua still had a lot of questions to ask her.

Of course, the first goal is to find the [Ecological Cycle Zone] first, after all, they don't know how long they will stay here, and the source of food and water is very important, after informing 3 of this, the AI led them to a passage that leads to the bottom.

The interior of the massive pyramid has countless interlaced passages, some of which are illuminated by blue light, some of which have been completely extinguished, and according to Number 3, due to the lack of personnel maintenance, even if the mobile fortress has the ability to self-regulate, it has accumulated a lot of irreparable damage over the millennium.

"We're crossing the energy storage area and we're almost there." No. 3 calmly reported: "The food storage area is on the other side, but after a thousand years, it has probably all been reduced to dirt. ”

Above all of us is the core dogma area that regulates energy transportation in the center, and below it is the living area and ecological cycle area of human life.

The light in front of her grew brighter and brighter, and without the reminder of Number 3, Joshua could feel the breath of life more and more obviously, which was the exact opposite of the dead and barren wilderness outside the pyramid, and the corners of Kleel's mouth were slightly upturned, and she also sensed the message of natural existence.

The steel passage began to expand, the original passage began to become wider and wider, and the flow of the wind began to become more obvious, and everyone continued to move forward, and finally reached the end of the passage, they stepped through a translucent barrier of magical power, and entered a vast space.

The surging breath of life rushed to his face, and Joshua raised his head and looked at everything in front of him.

As far as the eye could see, there was a blue-green world, with a huge man-made earth and sky dome stretching endlessly before his eyes, and compared to this huge space, their group was as small as ants. Lush exotic plants shake their blue-green leaves and make rattling noises in the wind, while the black-brown earth is littered with scattered shrubs and weeds.

"Here, it's the ecological cycle zone."

In the voice of Number 3, everyone observes the world.

"It's really impressive." The old dwarf sighed with emotion: "I didn't expect that there really is such a large piece of land in this pyramid. ”

He squatted down, grabbed a handful of dirt and rubbed it in his hand, and nodded: "The soil quality is not bad, not loafer, but it is still within the normal range." ”

Clere also observes the surroundings, fields, forests, hills, cliffs, and the small lake not far away, in the huge space inside this pyramid, everything is there, although it is tiny compared to the real world, but it is indeed a complete ecological cycle......

No, it's not complete.

Because whether it was Joshua or Rin, Moria or Cleel, the four of them did not find any trace of half an animal in their observation for a period of time, and all they saw were some silent ancient trees and scattered small plants, not even insects.

"Only plants are stable."

Seeing the confusion in everyone's eyes, Number 3 opened his mouth to explain, and a calm and emotionless voice sounded: "The artificial cycle of nature is fragile, and without the adjustment of the Karlisians, it only takes the slightest mistake to cause irreparable destruction here...... In this absolutely safe and closed environment, all animals have exhausted their potential, and repeated inbreeding leads to more severe genetic diseases, and even makes them lose the ability to have offspring, and gradually self-extinguish. ”

Speaking of this, No. 3 seemed to be laughing at himself: "Just like the world out there, in fact, these plants are about to be unsustainable, and I have tried my best to maintain the stability of this ecological cycle after the extinction of the Karlis, although it has been effective, but it is not large." ”

Neither Moria nor Cleel understood what 3 was saying, and their brows furrowed, while Rin explained to them.

“…… Well, indeed, she's right, and the plants here are dying. ”

After listening to Rin's relay, Cleel crouched down and gently touched the grass and shrubs around her, her hands flowing with a light green sheen. She closed her eyes and communed with the tiny piece of nature.

Then the elf sighed and stood up, she shook her head, and said nothing.

And Joshua and Moriah were looking around, and their faces were not much better. Although they are prepared for the worst, and the current situation is not bad, there is no room for optimism.

"It doesn't matter if there are no animals, even if it's the bark of a tree, I can digest it and convert it into energy." Joshua's brows furrowed slightly, he took a step forward and whispered to Number 3, "But what happened to the large and large pieces of bones buried underground. ”

He waved his hand, and the red fighting spirit lifted up the soil, and suddenly countless white bones of various creatures appeared in front of everyone's eyes, including unknown creatures and Karlis, all the bones were covered by a thin layer of soil, buried under the earth, most of them were extremely broken, only a little bit of stone-like remains remained.

Moria, who had also noticed this before, didn't pay attention to the bones, he just stood behind Joshua, his brow furrowed, and watched with golden eyes as the warrior communicated with Number 3 in a language that no one could know.

Joshua Radcliffe, a descendant of the deceased who inherited the name of the Radcliffe family, this warrior who simply returned to his hometown after learning of his father's death, and inherited the knighthood, has always done things that can be compared to miracles, whether it is the elimination of his uncle's knighthood team by himself, or the defeat of the Kuroshio Tide twice in a row to close the space-time gate, and this time because he came to this world on the verge of the end of the world by accident, it is also because of the steel crystal he brought you.

And he can actually speak the language of another world, and can communicate with artificial intelligence beings in another world...... It all felt so weird, as if it had been set up for a long time.

"The Gods are above......

The old dwarf muttered, "Damn, it's almost like a legend." ”

Even if he didn't believe it, he couldn't help but think of the word fate in his heart.

And Joshua is still communicating with Number 3.

"These bones in front of you are the remnants of the warriors who fought against Chaos thousands of years ago."

The black-winged AI replied to Joshua's question: "In the last days of civilization a thousand years ago, they decided to die here without seeing any hope, not only here, but also many bones in the Church of the Crystal Sun above, I think you have all seen it." ”

After a slight pause, No. 3 seemed to be processing the information in the fortress, and then said: "There are more bones in the nearby living area, most of them have been broken down by magical power, and it is their souls gathered in the central dogma area of the fortress that gives me wisdom." ”

"Yes."

Nodding slightly, Joshua suddenly thought of something, and his voice passed through the armor, looking a little dull: "No. 3, have you been wandering on this land for many years?" ”

"One thousand and seventy-two years to be exact."

No. 3 bowed slightly: "Of course, if you refer to my autonomous consciousness, then it is only nearly a thousand years. ”

"Good."

Joshua was very satisfied with this answer, and he looked directly into the eyes of the artificial intelligence projection: "So can you explain to us the reason for those strange phenomena in the outside world?" There are also some special regions in this world. ”

The warrior pointed to something: "Like the place where the Aragami gathered." ”
