The tunnels are wide and deep, with intricate structures, and crystal fragments used for lighting everywhere, making this vast underground space feel dark and terrifying.

Egner, who was piloting the flying machine, continued to fly deep underground, and Yang Rui had already turned into a transparent prototype at this time, following closely behind him.

The walls of the tunnel are crisscrossed with pipes and all sorts of mechanical equipment. Yang Rui lamented that all this came so quickly, and Aigner had already walked the spark of scientific and technological civilization on this planet.

The aircraft carried Aigner to the end of the tunnel, where was a wider and huge space, Yang Rui flew out of the tunnel and found that this space extended down to the place where the line of sight could not be seen, and the ground had been opened above, and countless tunnels were connected around it, and the noise from various machines was endless. However, even though it's underground, the air circulation is very smooth, and you don't feel the congestion at all.

Yang Rui was not only impressed by Egner's great achievements, this race was not created by him, so Yang Rui couldn't control these visitors in spirit and will, let alone what they were thinking, but all this in front of him still made Yang Rui feel that he had underestimated their energy.

When Yang Rui was hanging in this underground space and didn't know how to continue from that road, suddenly another flying machine appeared behind him, and this flying machine was standing on Elus, she said to Yang Rui with a smile: "Welcome, my master!" ”

Yang Rui saw Eloth on the aircraft, and her beautiful face did not change at all. The only thing that has changed, though, is that she no longer resembles a huntress but more like a warrior, and her tight-fitting clothes perfectly fit the elegant and slender lines, showing off her style.

Yang Rui also smiled back and said, "It's been a long time, Elus!" I'm here to marvel at the great achievements of your Aigner. ”

Elus said, "This is all thanks to you, without the water of the holy lake that you have given us, we would still be a group of ugly and dirty creatures." ”

Yang Rui has a lot of interests here, and he doesn't want to take up too much time on such a boring topic as the water of the holy lake, so he said urgently: "Take me around and see what new things you have invented." ”

At this time, Elus slammed on the pole console a few times, and within a few seconds, an unmanned aerial vehicle appeared out of nowhere and stopped beside Elus.

Elus's eyes flashed with wisdom, and she looked at Yang Rui mischievously and said, "I finally let that little piece of iron fly." My master, please feel it for yourself. ”

Yang Rui turned into an Aigner, a flipped over and jumped onto the flying machine floating in mid-air, this guy seemed to be a little restless, and at the moment Yang Rui jumped up, he moved forward, so that Yang Rui had to quickly grab the longitudinal rod with both hands so as not to fall into the deep pit under his feet.

Yang Rui found that this aircraft is not like a high-tech product, the brass material shines with a simple and heavy texture against the background of the surrounding light, more like a metal handicraft, Egner's ancient totem ornaments are all over the body, and various retort modules are perfectly integrated in this ornament, without any sense of abruptness, natural and exquisite.

"I solved the problem of the second thrust and it was able to fly freely," said Elus. ”

Yang Rui looked at the Module and asked, "How can I make him fly?" ”

Elus sat down and demonstrated, "Hold on to the rod and use your consciousness to drive it and control it." ”

Yang Rui tried it according to what Eluss said, and sure enough, the flying machine flew up according to Yang Rui's consciousness. Yang Rui was a little uncomfortable at first, but soon he mastered the trick and made his flight posture in the air look less funny.

Eluss followed Yang Rui and said, "This is already an improved type, and it still needs to be manually mechanically worked at first. This latest generation of aircraft can be connected to the consciousness of the controller, ensuring that the aircraft can make the most accurate execution of the controller's commands in the shortest time. ”

Yang Rui said while controlling the aircraft: "It is indeed very easy to control. It's like your own body! ”

Elus suddenly changed her flight trajectory and flew deeper, saying, "My master, follow me." ”

Yang Rui hurriedly chased after him, and flew at high speed in the tunnel with Elus, one after the other, constantly passing by Aigner, who was piloting the aircraft.

Continuing the topic of flying machines, Elus said, "At present, we can only build such small flying machines, and larger ones are still being studied. ”

Yang Rui asked: "Does this aircraft use anti-gravity as the driving principle?" ”

Elus turned her head and looked at Yang Rui with a smile and said, "The magnetic field of this planet is the source of the power of this aircraft. Although it is a product of technology, it all comes down to the power you have given us. ”

Yang Rui asked: "What problems do large aircraft encounter?" ”

"There is no technical problem with the control of the flight, the problem is with us at Aigner. The speed of the large aircraft is too fast for us to withstand this gravitational effect, so we are still working on this puzzle. However, I am sure that it will be resolved soon. ”

Yang Rui smiled and said, "You speak in a tone that looks like a scientist now. ”

Elous laughed and said, "You're the greatest scientist!" I'll take you to see your great scientific achievements. ”

Alus led Yang Rui into the most body layer of the tunnel, and at the end of the tunnel was a huge metal gate, and Yang Rui could feel a powerful biological energy rushing towards him, continuously penetrating his body.

Elus pulled the craft to the ground and reached for the wall to activate the Module. The metal gates opened with a dull sound.

A faint blue light flashed from behind the door, and the sparkling light flew in all directions, and the scene was simply beautiful.

Yang Rui was led into the gate by Elus. Behind this gate lies an even larger space, an incomparable pool that occupies almost the entire space.

The dark blue liquid in the pool rippled slowly and softly, and countless points of light flew out from here, flying around like fireflies.

In the middle of the pool is a huge pipe that leads to the top of the space, and I don't know where it leads.

Elus walked to the pool and sighed, "Every time I come here, I feel the greatness of God. You have created everything, and we at Aigner have made it from this pool. ”

Yang Rui also walked to the edge of the pool, he squatted down, picked up some dark blue liquid in his hand, and said, "This liquid is full of spores." ”

"Yes." Elus nodded and said, "You gave us the first spores back then, and now there are so many. This pool is the source of Aigner's strength, and it is where all the energy we need comes from. ”

Yang Rui asked, "Where does this pipeline lead and what does it do?" ”

Elus turned around and picked up a heavy piece of metal from the corner and said, "We also made this out of spore energy. ”

Yang Rui took the metal block and immediately felt its weight and hardness, it was jet black and the material of the flying machine and all of Aigner's construction machinery was exactly the same.

However, when Yang Rui felt the metal carefully, he felt that there was also a faint biological energy emitting from it, so he said, "This is not processed from any ore. It's not metal at all, it's alive. I could feel it breathing and growing. ”

Elus nodded and said, "We've changed the biological structure of the spores to make them a completely different form. It becomes incredibly hard, even more durable than metal, and repairs itself like life. The most important thing is that it does not cause any pollution at all. ”

Yang Rui rubbed the piece of metal in his hand, and gradually the thing was no longer hard, but slowly became soft, until it finally broke into a small pool of dark blue liquid.

Yang Rui put the liquid back into the pool and said quietly, "Aigner always surprises me. ”

"We have followed your will to develop our civilization, and although we do not like it, I prefer to live close to nature without reservation," said Elus. So in order to get the best of both worlds, we gave up the various ores and trees that were readily available, and instead researched these more sophisticated technologies, just so as not to destroy the very essence of the planet. ”

Yang Rui smiled and asked, "It seems that Cesarian accepted my request against his will." ”

Elus sat down on the edge of the pool, took off her boots, soaked her feet in liquid, and said with a smile: "He was not interested in new things, he preferred to follow tradition, so he took the like-minded elders of Aigner back to the deepest part of the sacred lake forest and lived the way he used to live." ”

After saying that, Elus let out a long breath and said, "The new generation of Aigner like me prefers this brand new city above me. ”

Yang Rui also sat down next to Eluse and said, "I will definitely look at your father and thank him, and at the same time apologize." ”

Elus smiled and said, "Then I hope you will give him a sharp-toothed beast, as a gift, he will surely die of joy." ”

Yang Rui asked, "What is this, why?" ”

"With the advent of flying machines, the new generation of Igner's hunters no longer rides Toothed Beasts. My father was very much against this. However, most of the Tooth mounts were released back into the wild. Now I am the only one who has one, and when he sees people, he complains that the new generation of Egner has forgotten the tradition and can only fly flying machines to run around in the sky. ”

Yang Rui also smiled and said, "I will definitely do it." ”

Elus was silent for a while and suddenly asked, "Are you doing well?" ”

Yang Rui felt that Elus's tone seemed to be used only for an extremely close person, and at the same time, Elus's charming eyes were particularly charming in this vast and dark space.

He smiled faintly and said, "Of course it's good." ”

"What are you doing?"

"Sleep."

"After sleeping for so long, it looks like it must have been a good night's sleep."

Yang Rui nodded and replied mischievously: "Of course, otherwise you made such a big hole in the top of my head, and I wouldn't have noticed it at all." What a failure I've done as a god. ”

Eloth laughed and said, "You can always make me laugh." ”

The two sat side by side, and after a long time, Yang Rui stood up and said, "It's time for me to go." ”

"Let's go?" When Eloth heard this, a sense of loss appeared on her face, and she asked, "Where are you going?" ”

Yang Rui didn't look back and wanted to walk out of the gate, and at the same time replied to Eluse behind him: "I've slept for too long, this world has changed so much, I need to understand clearly." ”

Yang Rui and Elus silently left the pit and came to the forest, at this time it was already night, Yang Rui sighed with a sigh: "The night of the Holy Lake Forest is really beautiful. ”

Elus looked up and said, "Especially when the moon comes out, the moonlight can spread all over the forest, and I like to sit in the treetops and watch the moon at this time." ”

Yang Rui asked, "Looking at the moon, what do you remember?" ”

Eluss forgot to glance at Yang Rui but did not speak.

Yang Rui didn't ask any questions, raised his head and looked through the gap in the canopy to find the moon in the sky. But just as he looked at the sky, the moon had just revealed its face from behind the dark clouds that had dispersed, but not far away, another moon suddenly appeared above Yang Rui's head.
