The Queen of Qingling was speechless for a long time, and her heart was sad for her race.

Lydia Frost Moon's mind is much simpler, she was born on Gasmanda Island, she is not yet fifty years old, she has not experienced the war of conquest of the year, and she does not have a deep sense of the past glory of the Qingling Clan, she now has only one thought in her mind, and asked directly: "Your Excellency, is the Federation the greatest country in the world?" ”

Xin Lin couldn't help but laugh, the Qingling Clan's perception of the world was really narrow and terrifying.

He shook his head and said, "Unfortunately, it's not. ”

Lydia Frostmoon was surprised, "Is there a country stronger than the Federation?" She couldn't imagine that there was a more powerful race in the world than a federation of 600 billion people.

"Of course there is, and there are countless of them." Xin Silent sighed and said, "Maybe the Federation is already very powerful in your opinion, in fact, there are at least a thousand civilized races in the galaxy that are stronger than the Federation, and the Federation is just one of the small and unknown countries. ”

Lydia Frostmoon listened to Xin Lone's description, and her heart was shocked, but it was difficult to understand the information.

"And what is the Milky Way?" Queen Qingling asked.

Xin Lin simply continued to operate the holographic map, and the picture quickly flashed back to the Elite Star, the perspective was pulled away from the surface, and soon entered space to see the full picture of the Elite Star, and then two suns appeared.

"You should be familiar with these two stars, you call them Tiboro and Chalinya, all the light and heat on the star come from these two suns, without them, there would be no you. Among them, Tipolo is a yellow dwarf, and its size is 350,000 times that of the Yixing Spirit, which is very scary, right? But there are 200 billion stars in the Milky Way! ”

The hologram flashed, and the panorama of the Milky Way was presented in front of the two Qingling people, and the beautiful galaxy slowly rotated, attracting their attention at once, looking greedily and forgetful.

"It's beautiful!" The two muttered to themselves.

Xin Lin magnified the three-dimensional image of the Milky Way a hundredfold, and after a dazzling switch, Orion's spiral arm spread out in the pavilion, he pointed to a tiny binary star system above his head, and said: "This is Tiboro and Chalinya, they are just the most ordinary existence in the galaxy. ”

"Every point of light here represents a star, and every star in the sky has a world."

"This is the Milky Way, but ......" Xin Silence paused, looked at the two and whispered, "The Milky Way is like dust in the vast universe, like a grain of sand on the beach, insignificant!" ”

"The diameter of the Milky Way is 100,000 light-years, and above the Milky Way is a galaxy group and galaxy cluster composed of dozens to hundreds of galaxies, and dozens of galaxy clusters form a supercluster, which is only a part of the large-scale fiber structure, and there are about two trillion galaxies in the entire universe, and the universe is so large that it is beyond the limits of imagination."

The sound of Xin Silence was not loud, but it was deafening like a thunderstorm in the ears of Queen Qingling and Lydia Frostmoon, and at this moment, their worldview was shattered by the impact, and their chests were suffocated, as if it had become difficult to breathe.

The two looked at the three-dimensional image of the Milky Way with a blank expression, and couldn't say a word for a long time.

After a while, Xin Xiao turned off the projection, and the two slowly came back to their senses, and the Queen of Qingling smiled bitterly: "Is this the real world?" It turns out that we are so small that everything we do is meaningless when we look at the whole universe. ”

Lydia Frost Moon's eyes were also sad, as if her heart was dead.

Xin Lin can understand their psychological state at this time, no matter who they are, when they see the vastness of the universe and feel the shock, they will have a sense of powerlessness in their hearts, doubting the meaning of their own existence. If you don't adjust in time, you will be immersed in this abnormal state for a long time, your emotions will be aggravated, and you will even have thoughts of suicide.

What's worse is that the worldview of the Qingling clan is still in the primitive stage of extremely backward observation with the naked eye, and even the concept of planets is very vague, and the impact of the vast universe on them can be imagined.

There is no way to explain this situation, so they can only wait for them to adjust themselves.

There was silence in the pavilion for a long time, after all, Queen Qingling was a strong person at the level of a martial saint, and her mind was far firmer than ordinary people, so she was the first to recover, let out a sigh of relief, and said to Xin Lian: "Let you see you laugh." ”

"It's okay, in fact, I myself often fall into this kind of self-doubt, and when I used to take astronomy classes, I didn't dare to think about it deeply." Xin Lone's face was not colorless, and he did often feel great awe of the universe.

Queen Qingling turned around and patted Lydia Frost Moon, who was still unable to extricate herself, and asked curiously, "You mentioned the word light year many times just now, is this your unit of distance?" ”

"That's right." "A light-year is the distance that the speed of light travels in a year, and this year is the year of our Federation. ”

"Light has speed?" Queen Qingling's face showed a strong desire to learn.

"Of course, the speed of light is a very important constant in the universe." Xin Xiao quickly calculated in his heart and said, "Using the length unit of your Qingling Clan, one light year is about thirty trillion 'thousand steps'. ”

"Thirty trillion ......" Queen Qingling felt her scalp tingle, this number was too big and too unreal.

In the life of the Qingling people, Gasmanda is almost equal to this world, this island does not have five thousand "thousand steps" from east to west, and what is the concept of thirty trillion "thousand steps", Queen Qingling can't imagine it at all. She remembered very well that Xin Lin just said that the Milky Way was 100,000 light-years away, and the Eleonstar was 372 light-years away from the Earth, so how many "thousand steps" away was the Earth?

Queen Qingling tried to calculate the distance from the Earth to Yiling Star, but she was dizzy at the beginning of the calculation, and she had to give up, she understood that she could no longer use "far" to describe this journey.

"How did you get here from Earth so far?"

Xin Lin smiled and said, "This is the power of technology." ”

In the next few hours, Xin Lin combined with the mobile phone demonstration to roughly introduce the concept and application of science and technology to the Qingling Queen, the Qingling Queen is very curious about everything in the Federation, the questions are one after another, almost non-stop, Xin Lin tried her best to answer her in a simple and understandable way. Of course, Xin Lin had a good grasp of the balance, and some things that should not be said, such as information related to federal secrets, were skipped, or vaguely said that he didn't understand.

It was getting late, and it wasn't until the two rounds of the sun were about to set that Queen Qingling couldn't stop unsatisfied, although she still had too many things to ask Xin Lone, but it had taken up Xin Lone's time for too long, and today could only end here.

"It's a pity that you're about to leave Gasmanda, and I don't know if I'll have a chance to meet you in the future." Queen Qingling said very regretfully.

Xin Xiao hesitated for a moment, but still said: "Actually, I will go back very close to you, in the training camp on the other side of Gasmanda. ”

Queen Qingling was suddenly surprised, and asked eagerly, "That training camp for the Kryptonite Hand?" ”

"Yes, Your Majesty knows?"

"I heard Mr. Xiahou mention it once during the negotiation, and when our Horned Eagle Beast Knight patrolled along the coast, across the sea, I could vaguely see that there was a human sentry post on the opposite side, built in the canyon left by the war, where it used to be our city, but it was destroyed by the Federation with a terrible weapon."

As she spoke, Queen Qingling's eyes suddenly lit up, and she asked with a smile, "Xin Lian, are you interested in our swordsmanship?" ”
