Li Jiangyao had already walked to the front of the building at this time. If you look closely, the entire prehistoric human museum looks like a metal fortress, which is tightly sealed from top to bottom, left and right, which should be to maximize the protection effect.

A metal door, more than six meters high and two meters wide, closed tightly.

Xiahou Ninghan pointed to the gate and said, "I thought of a lot of ways yesterday, but I couldn't open it, otherwise I would have gone in and had a look." ”

Li Jiangyao looked at the door seriously, then walked to a machine similar to the access control, and reached out to touch the metal panel of the access control.

Suddenly, the original silvery-white metal plate became like transparent glass with the touch, and a faint fluorescence appeared.

At the same time, his face is captured by hidden cameras, projected onto the panel.

Xiahou Ninghan showed a surprised expression again, looked at Li Jiangyao in surprise, and was speechless for a while.

Li Jiangyao stared at the screen quietly. A line of words gradually appeared on the screen: Biometric system confirmed, human visitor, number 000001.

"Dear civilized visitors, welcome to the museum, please enter your name or code name."

The input system provided on the screen is different from the input method of electronic products in the modern world, but for Li Jiangyao, the two are not much different in nature, so after a little pondering, he simply typed his name neatly.

Then, he pulled Xiahou Ninghan over again, and also used the camera to capture the image information and name information.

The access number that Xiahou Ninghan got was 000002.

The electronic message prompt appears again: Do you want to enter the museum now?

Li Jiangyao couldn't help but smile and said, "We are actually the first batch of visitors, and I don't know if there are any welcome gifts?" He reached out and clicked the OK button.

With a slight airlock sound, the heavy metal door slowly moved open, revealing the space inside.

"Let's go, go in and have a look." Li Jiangyao very skillfully took Xiahou Ninghan's hand this time and walked into the museum.

The whole museum didn't know what kind of energy it used, but as soon as the two of them entered the door, the hall in front of them suddenly lit up. Although there is no obvious light source in sight, the light is soft and warm, and it looks very pleasant.

This scene is completely different from Li Jiangyao's previous imagination. Sci-fi movies are often cool, cool colors, but there is a kind of homely warmth here. Xiahou Ninghan felt such a light for the first time, and his eyes were full of curiosity.

The two of them looked around, and there were no items placed in this front hall of about two or three hundred square meters, only a line of large characters on the front wall:

The years of civilization are bright and short; The years of civilization have been vicissitudes and long.

Next to the wall, there was an oval metal shell, and Li Jiangyao recognized the signs on the shell at a glance: two small people and an up and down arrow.

This is probably an elevator, right?

Li Jiangyao walked over quickly, and was about to look for the button, but he didn't expect that the metal shell seemed to sense him, and he was able to open a small door with a brush. He didn't even think about it, he was about to go inside, Xiahou Ninghan hurriedly grabbed him: "Be careful, it's dangerous!" ”

Li Jiangyao smiled calmly: "Believe me, it's okay." So saying, he dragged her into the metal shell.

Obviously, this oval metal shell is a kind of elevator that moves by magnetic levitation, and as soon as the two enter, the small door closes immediately, and then directly ascends to the higher floors.

Xiahou Ninghan looked around a little wary, and at the same time couldn't help but wonder why Li Jiangyao didn't look nervous at all. She secretly said in her heart: People who are used to the battlefield are really different.

The lift stopped, and the small door opened again.

Xiahou Ninghan was startled. In the blink of an eye, there is a different space outside, which is as magical as the streamer mountain wall. Li Jiangyao was not used to seeing her, and pulled her out directly.

The kind of heroism that did not take the danger in his eyes at all made the cautious Xiahou Ninghan secretly admire, and at the same time, he felt that following Li Jiangyao's side made his heart much more steady.

This floor is very richly arranged, with shiny glass covers filled with all sorts of items.

From the Stone Age to the Iron Age, from the mechanical industry to the electronics industry, the most representative products that have ever appeared in the long river of human civilization are vividly displayed in front of the two of them in the form of physical objects or models.

Among them, there are many items with a sense of futuristic technology, which even Li Jiangyao has never seen.

He and Xiahou Ninghan held hands, like a couple visiting a novelty market, wandering among the exhibits.

For exhibits such as guqin, ancient sword, and ancient scroll, although Xiahou Ninghan felt very precious, he was not very surprised. What surprised her was the product of modern technological civilization. She grabbed Li Jiangyao's arm tightly, pointed to the camera and asked questions, and then shouted at the electric car.

An ordinary projector can make her look at it for a long time.

These things basically didn't jump out of Li Jiangyao's knowledge, so he explained them to her one by one in a way that Xiahou Ninghan could understand. Xiahou Ninghan looked at Li Jiangyao with admiration on his face: "How do you know about these novel treasures?" Is it really a genius and self-taught? ”

Li Jiangyao smiled embarrassedly: "Isn't there a text introduction next to it, I just simply understood it." ”

Xiahou Ninghan glanced at him with a smile and didn't speak, but his eyes were full of approval.

Of course, there are also futuristic technologies that Li Jiangyao didn't expect, such as the glove-type stun gun. As a non-lethal police equipment of the future, as long as the gloves are put on, the fingers can shoot electricity like a gun to subdue criminals.

Li Jiangyao was so fascinated that he couldn't wait to pry open the glass cover on the spot and take the baby away.

I don't know how long I walked around, but the two came to a circular field.

Li Jiangyao's eyes were sharp, and he suddenly found that there were several strange-shaped equipment in the glass cabinet next to him. Judging from the style and usage logic, these things are light and thin, and smaller than ordinary glasses, probably similar to VR glasses.

Without saying a word, he walked over and took out the equipment, handed one to Xiahou Ninghan, and put the other on himself.

Xiahou Ninghan looked at the strange thing in his hand again and again, and said strangely: "How do you know to block your eyes from this thing?" What is it for? ”

Li Jiangyao stubbornly flickered and said: "I don't really know, I just think the shape and size of this thing is the most suitable to wear on the eyes, let's try it." ”

Xiahou Ninghan had already been impressed by his erudition and intelligence, so he followed his example and carefully put on the equipment.

Sure enough, as Li Jiangyao expected, this is the VR of the future world, but the function is many times stronger than the products of the modern world. As soon as they put on their glasses, the scene in front of them suddenly changed: the primeval jungle was lush and green, and the vast grassland as far as the eye could see was full of unnamed birds and beasts.

Xiahou Ninghan sighed, and was so frightened that he hurriedly took off his glasses, and when Li Jiangyao saw her quit the system, he also quickly removed the equipment and comforted: "Don't be afraid, it's just some illusions, it's okay." ”

Xiahou Ninghan looked at him in surprise: "Is it an illusion?" But it was so realistic just now, I thought it was ...... again."

"Don't worry, I'm here." Li Jiangyao smiled and stood closer to Xiahou Ninghan: "I'm right next to you, you just need to follow me." ”

Xiahou smiled coldly, didn't say anything, and silently put on the equipment.

This time, she was obviously much calmer than before, but her body was also closer to Li Jiangyao.

The two returned to the virtual scene again, and the system began to show them the progress of human civilization according to a predetermined rhythm.

The circular court is equipped with a self-gravity mediation system, and even without wearing equipment, Li Jiangyao and Xiahou Ninghan can experience the true feeling of weightlessness. The system took them through the vast starry sky and ocean, on the vast mountains and rivers, observing the ancestors of mankind from the perspective of God, watching them move forward with difficulty, accumulating wisdom and civilization bit by bit, and finally stepping into a civilized society.

Xiahou Ninghan never thought that he could have such an experience, and he exclaimed excitedly, and his hand holding Li Jiangyao became tighter. Li Jiangyao was much calmer, and from time to time he made a few jokes with Xiahou Ninghan, which made her giggle.

The record of civilized society is not peaceful.

Dynasties and countries have risen in the tempering of war, built brilliant fruits of civilization, and then fell into the abyss of war again, allowing barbaric violence to destroy the prosperous era.

Ups and downs, cycles and cycles.

Xiahou Ninghan was immersed in the joys and sorrows of the long river of history, and he was stupid. It wasn't until the end of the two-hour explanation that she suddenly found that her hand was holding Li Jiangyao's hand tightly, and her palms were full of sweat.

She took off her glasses and felt that there were too many questions to ask, but she didn't know who to ask or where to start.

Witnessing the final destruction of the earth's civilization in the flames of war, Li Jiangyao couldn't help but sigh softly, Xiahou Ninghan thought about it and asked him, "That fusion weapon, do you know what it is?" ”

Li Jiangyao was stunned. Fusion weapons are the product of mankind's entry into a highly technological civilization, and although its principle is similar to nuclear fusion, it is not exactly the same. He thought about it for a moment and tried to explain: "That should be the most primitive and core force in the universe. When the mechanism of a microcosm is completely changed, it will unleash the power to destroy the world, and this is probably the case with fusion weapons. ”

"So what is the microcosm?" Xiahou Ninghan asked curiously, "Is it the same as the world we live in?" ”

Li Jiangyao said in his heart: This ghost thing, I'm afraid only philosophers or physicists can explain it. But luckily you're an ancient, and I can still fool as much as I can.

He cleared his throat and said solemnly: "I understand, the world that we can see with the naked eye should be called the macrocosm, and those that are so small that we can't see with the naked eye are the microcosm. I don't understand, do you? Well...... Let's put it this way, one sand and one world, one leaf and one Bodhi. As small as a grain of sand, they are all a world, with everything in the world like us, and it is self-contained. And we, for the vast universe, are also a small grain of sand. ”

Xiahou Ninghan's eyes lit up: "You're talking about Buddhism's "Treatise on Great Wisdom", right?" Tens of billions of Mount Meru, tens of billions of sun and moon, called three thousand worlds. ”

"Yes, yes, that's what it means," Li Jiangyao nodded: "The small thousand worlds form the middle thousand worlds, and the middle thousand worlds form the big thousand worlds." The size of the world is relative, this is the supreme wisdom, Amitabha, good, good. ”

Although he said it indecently, and even he felt extremely unreliable, Xiahou Ninghan's beautiful eyes flashed with brilliance, and even his address to him changed: "Jiang Yao, I didn't expect you to be so knowledgeable and have a deep understanding of the principles of Buddhism. I have always been ignorant of the truths that I said in the fantasy world, but as soon as I heard you break it down, it immediately became much clearer. You...... It's not easy. ”

Li Jiangyao was embarrassed by her praise, and hurriedly smiled: "I'm just talking nonsense, I can't take it seriously." ”

"Don't say that," Xiahou Ninghan's cheeks suddenly turned red: "Before, I only knew that you led your troops to resist the enemy and swept through the Eight Desolations, and you were a great general. But from the bottom of my heart, I still confuse you with those rude soldiers who only know how to fight. Only now do I realize how wrong I was. Except for his father, Ning Han has never seen anyone as talented and admirable as you. ”
