"What? At a depth of 400 kilometers underground, can you still see the sunrise? Cao Fang's words, Shen Yun was dumbfounded again.

Cao Fang explained casually: "You just need to remember that many of the elements of life here are set up in the opposite direction of the ground, so you won't feel so strange when you see incredible phenomena in the future." ”

Shen Yun became more and more confused the more she listened, and she could only sigh that her brain was turning too slowly, "What does this 'opposite' mean?" And why do you want to set it the other way around? ”

Cao Fang finally told the truth: "The AI intelligence leader who controls the Light Continent is called Yunhe Shenwei, he is the 'human' with the highest IQ on the earth so far, of course he is a robot. Yunhe Shenwei's built-in processor is composed of photons, reaching a speed of 100 billion operations per second. It can be said that all robots, including RAND 2, are the children of Yunhe Shenwei, and the humans living here do not need to do any transactional work, and can rely on AI intelligence to complete everything, including the change of the sun and the moon, the change of seasonal climate, and so on. But ......"

His tone took a turn.

"But after all, the main technology of the underground science and technology federation is from alien civilizations, and it lacks a certain degree of secrecy for the enemy. We need to especially protect the atmosphere that envelops the continent of light, at absolute zero, and defend against possible light reconnaissance by the enemy. If the freezing environment is destroyed, the enemy may invade Yunhe Shenwei and paralyze our military and urban systems. So everything here seeks to be the opposite of the ground in order to confuse the enemy's audiovisual view. ”

Shen Yun didn't seem to understand, and tried to guess: "Those aliens, are they not very good at reverse thinking?" ”

Cao Fang gave her a thumbs up: "Clever! You guessed the point. Those guys are incredibly cunning, and it's not an exaggeration to call them high-IQ creatures. But if they are asked to be detectives, they can't do it according to a phenomenon and deduce the process of occurrence from the result. To use professional terms, it is a lack of thinking about seeking differences, and it is difficult to summarize the law of unity of opposites. ”

As the two spoke, Shen Yun was surprised to see the black clouds in the distant sky, as if they were tearing open by a hand, and a wisp of pale white glow flowed out like thick milk.

In the blink of an eye, the milk color deepened and turned red, glowing as if it were burning. If you think of the object behind the hidden cloud as a large head, the burning part is like a smooth head with golden-red hair fluttering on it.

When the red glow dispelled the darkness of the sky, the glowing object revealed its true shape, and it was really a round sun, announcing the arrival of morning. However, compared with the early morning on the earth's surface, there is less romantic cloud dyeing process, and the speed of sunlight bursting is shortened in an instant.

Although the romantic atmosphere has weakened, the beauty of the rising sun expressed by the luminous body is not inferior to that of the real sun. A layer of golden streams cascades down the top of the sleek, arc-shaped building. The luster of the buildings weakened with the enhancement of sunlight, and at this time, Shen Yun saw their appearance clearly, every beam and every piece of masonry of the building seemed to be made of crystals of different colors, and the name of the city that was more appropriate than the Light Continent should be the Crystal Castle.

"On Earth, it's dark." Cao Fang muttered, and Shen Yun felt tired as soon as she heard it.

For a whole day, she had been nibbling on a few mouthfuls of bread handed by Cao Fang in the jeep, hunger and headache, and the fright she received after entering the tunnel, now her legs were weak, her vest was sweating, and she was about to lose her footing.

At this moment, a bright white spot appeared on the S-shaped light track elevated in front of it, as if the subway had entered the station. She was just about to ask what it was, when the bright spot suddenly stopped in front of the two of them with a strange but nice tinkling sound.

"It's a big red and white capsule!" This was Shen Yun's first reaction after seeing the object in front of him.

It seems that Cao Fang has been waiting for this big capsule, and he didn't have any special reaction when he saw it arrive.

The scene that surprised Shen Yun reappeared, the capsule that looked complete and seamless, gradually protruding from the side of the red end with rounded corners, and when the square protruded into a separate plane, it slid to the left, revealing the inside of the capsule.

It turned out that the rounded square frame was the car door, and when the door slid open, a young man who also wore a military uniform and looked like he was in his twenties came out.

"Yao Zheng, the commander of the third brigade, greets the army commander, the army commander has worked hard!" Yao Zheng stood upright and saluted Cao Fang.

Cao Fang returned the salute, and the two shook hands with each other, and Cao Fang patted Yao Zheng on the shoulder, making love with him like a brother.

"Xiao Yao, why are you here to pick us up? Wouldn't it be possible to start the capsule tram's automatic control system directly? ”

Yao Zheng shook his head and replied resolutely: "How can that be done?" General Shen's daughter is here, and even the army commander has personally gone to pick up the car, how can we sit on the sidelines? After thinking about it, he added: "Don't worry, this matter is not only not scolded by the head of the regiment, but also very supportive!" ”

Cao Fang hehehe, nodded and said, "That's good, that's good." Then he pulled Shen Yun, who was standing aside, to make an introduction.

"This is General Shen's eldest daughter, Shen Yun."

Shen Yun smiled at Yao Zheng with tiredness, and when Yao Zheng mentioned her father, she could easily feel the reverence from her heart, which made her both proud and sad.

When you get into the capsule train, you can only sit two people in front of you and two people in the back at most, but it is as spacious as a five- or six-square-meter cabin. Excluding the cockpit at the front, the passenger compartment at the back is arranged like an elongated luxury car, with streamlined tables and chairs and wall-mounted decorations.

After experiencing it all the way, Shen Yun was no longer surprised by the new things that appeared again, but a delicate bronze wine rack placed against the wall of the car still aroused her great interest. She wondered, if the whole city belonged to the military, and the capsule tram was a military car, how could there be so much wine in the military car? Is it for guests to drink?

Just puzzled, Cao Fang, who was sitting next to him, really reached out and took a bottle from the shelf and handed it over, saying, "It's been a bumpy journey, I know you must be tired and hungry." Drink a little, and you'll be refreshed right away. ”

Shen Yun hurriedly refused: "No, no, no, Captain Cao, I won't drink......"

"Wine?" Cao Fang didn't shrink his hand, just smiled at Yao Zheng, who looked back from the cockpit.

Yao Zheng explained: "Xiao Shen, it's not wine, it's a functional drink with dozens of natural nutrients, called Lienengsu, and a bottle can replace a meal." ”

Sure enough, it's a disciplined army that doesn't drink casually! Shen Yun also smiled, took the bottle and took a look, the pure black bottle body was shiny like a black gem, but the liquid inside was pink, and it smelled of an indescribable fresh and fruity fragrance.

A bottle of Li Neng Su was swallowed, and the heavy fatigue was swept away, and Shen Yun felt as if she had just had a full meal, and she secretly surprised herself.
