"What do you know?"

Falling Hong's fanatical eyes, as well as that desperate gesture, made Zhang Yuan understand that after all, he still underestimated the scholars' thirst for knowledge.

This guy grabbed Zhang Yuan's neckline with both hands, and was about to lift Zhang Yuan up.

"You put me down first!"

Only then did Luo Hong realize his gaffe, and quickly let go of his hand and took a step back.

"Go out, the weather is good today, it should be a good day for stargazing."

You have to throw out something real to hook the heart of Luo Hong.

In ancient times, there were no tools to watch the sky, but the good thing was that the sky was really bright.

The atmospheric environment is much better than 2,000 years later, and later to see the Milky Way's light band, you may have to go to the plateau area, but now as long as the weather conditions are better and the sky is not covered by clouds, it is easier to see the Milky Way's light band.

And Chang'an City is on the edge of the Loess Plateau.

"Do you see the light from heaven?"

"You mean the brighter one?"

"Yes, that's the galaxy we're in right now."

"Galaxies?"

"Yes, the galaxy contains countless planets like the one we are in now.

But I really don't know if there's life in it. ”

"What else?"

"There are other things, such as dust, also known as cosmic dust, all kinds of matter that we can't distinguish.

Countless planets, cosmic dust, and all kinds of matter were pulled together by a single force, and they kept spinning. ”

Zhang Yuan only said a little thing, but it had already caused a huge impact on Luo Xiahong.

Luo Xiahong has been studying the theory of the heavens, and they believe that the stars in the sky are all points or projectiles embedded in the earth's sky.

These points revolve around the Earth.

Luoxiahong has built an armillary sphere in Chang'an in the past two years, and the armillary sphere was not invented by Luoxiahong, it has appeared before, but later Luoxiahong improved it according to his own ideas.

Now when their group of astronomers was still studying how to measure the movement of the sun and the moon, what Zhang Yuan threw out had greatly exceeded their understanding.

It is not an exaggeration to say that it is crushing.

Zhang Yuan just said the piece he was most unfamiliar with, and the most familiar thing for Zhang Yuan was naturally the solar system, the Milky Way and even the universe were too huge.

"It can't be!"

"Why can't it be?"

Luo Xia Hong pondered for a while and directly denied Zhang Yuan's statement.

If what you say is true, then what kind of god created such miracles?

The territory of the Great Han is already huge, and you say that there are other worlds like ours, which are unimaginable. ”

The first science associated with the gods was astronomy, and the gods and spirits dwelt in the heavens, which is why astronomy was one of the first sciences to appear.

Mortals want to know the secrets of the gods.

Zhang Yuan didn't know if there were gods or not, because there were too many things that could not be explained, and the more he knew, the more unknown things he had, and it was an endless loop.

"There may be gods or there may not be gods, and what I can tell you is that the world in front of us is not what you think it is.

Go into the main building and I'll draw a picture for you. ”

Luo Xiahong didn't know what Zhang Yuan was going to paint, and Zhang Yuan had already forgotten about hiding himself.

What Zhang Yuan wanted to draw for Luo Xia Hong was a rough version of the world map.

The fine Zhang Yuan can't draw it, but you can trace some lines to form a general appearance, and Zhang Yuan can do it.

"This is our current world, Dahan is in this position, it can be regarded as the center of the world, but it can also be said to be a corner."

Luo Xiahong saw the rough picture in front of him, and he still didn't believe it in his eyes.

However, Zhang Yuan is still relatively sure of this thing to persuade Luo Hong, at least people on the other side of the Eurasian continent can actually find it with great effort.

Once the Hexi Corridor is opened, we will have a general understanding of the West.

The farthest place that the Han people went at this time was the Pamir Plateau, that is, the Green Mountains, in fact, the Westerners also stopped there.

Everyone thought that if they continued to go to the east or west, they would be desolate as far as the eye could see, so they did not have the courage to continue walking.

"Impossible!"

Luo Xia Hong still said this.

Zhang Yuan spread his hands and expressed helplessness.

"You will believe me, in three years, the Hexi Corridor will definitely be taken by the Han Dynasty, and then all the countries in the Western Regions will come to the Han Dynasty to pay tribute, and you can ask the envoys of those small countries in the Western Regions at that time.

In fact, if you go to the desert with us this time, you can also ask those people from the Western Regions in Shangjun Qiuzi City. ”

Most of the merchants in the Western Regions who fled to the Han Dynasty were merchants, and the merchants of the Western Regions were the group with the most knowledge of the world at this time.

They knew that there was another country in the west called the Empire of Sabbath, and further west was the Roman Empire.

There are many countries that are similar to the Dayue clan in the middle, and those that are closer to the Han are Dawan and Wusun.

A little further away are Albania, Armenia and a bunch of countries with a Nizhania end.

Fortunately for Westerners, they did everything from Qin Shi Huang to Emperor Wu of the Han Dynasty in one generation of emperors, Darius of the Persian Empire.

But the Westerners unfortunately did not have a little time to accumulate two things, which is the reason why the West has not been unified since then.

Those two things are cultural identity and the concept of co-mastery.

Huaxia, on the other hand, spent more than 500 years implanting this concept until it penetrated into the bone marrow.

Therefore, the theory of Chinese people in the world is actually brought about by this concept.

Even the Huns were actually part of China in the eyes of the Han people, so Zhang Yuan's picture made it even more difficult for Luo Hong to accept.

"Okay, I'll ask myself then.

That's not what you know, right? ”

Zhang Yuan smiled, he really didn't know much, but he could create more doubts for Luo Xiahong.

"yes, I know a lot more."

"I wonder if Taixue Ling can tell me one by one?"

"Can't!"

"Huh?! Why. ”

"You see that you want to leave after reading the books of Tianlu Pavilion, if I tell you everything I know, then why don't you just go to the mountains to study?"

"No, it won't!"

"I won't believe you."

"Taixue Ling, how do you know so much?"

"When I was in Shu County, I knew some Hu merchants and obtained some Western books from them."

"What about the books, can you show me?"

"Have you forgotten what I just said?"

"Okay, I hope Taixue Ling can always remember this."

"Don't worry, do what you have to do, and I won't let you suffer."

"Uh-huh."

Luo Xiahong nodded, and then didn't care about Zhang Yuan, moved a chair and went out.

Zhang Yuan understood that Luo Hong would definitely not be able to sleep this night, and this guy must have been watching the stars in the yard all night.

As for Zhang Yuan, he didn't care about Zhang Tang, who was still eating, and went back to the room to sleep.

The next day, Zhang Tang and the two people in the palace waited until Zhang Yuan got up, and then left after saying a word.

Zhang Yuan watched them go home until they were gone.

Half a month later, Zhang Yuan applied to Liu Che to take 100 students and more than 20 lecturers and officials of Taixue, as well as more than 10 hunters and more than 200 veterans to set off for Henan.

Zhang Yuan's purpose is to prevent Li Guang, a lost general, from getting lost at that time, and the first places that need to be explored are naturally the Hetao area south of Yinshan and Henan.

The purpose of their group of people has long been thought out of the external world.

The tool man Chu Da appeared in front of everyone's eyes again.

Zhang Yuan's purpose is to assassinate Chu Da, at least that's what they say to the outside world, and it's their business to believe it or not.

In this way, the security will be higher, and if the people under the Aries King catch Zhang Yuan and them, they will definitely be sent to Chu Da.

Chu Da would not kill Zhang Yuan and them no matter what.

On the other hand, it will prove one thing more and more, Liu Che values Chu Da very much, Chu Da is a person with status, and Chu Da is very likely to have secrets that can threaten the big man.

Zhang Yuan: Their target location is Qiuzi City in Shangjun.

It can be said that except for some veterans, it is the first time for everyone to enter a city with such an exotic atmosphere.

Qiuzi City is just north of the Great Wall of Shangjun Qin, and it is also directly north of the Shangjun County City of Fushi.

There are no county orders in the city, and there is nothing too guarded.

This is a military city.

The highest commander in the city was a lieutenant of a subject country half a level lower than Zhang Yuan, and he had 5,000 Han border troops in his hands.

The Han people who haunted this city were actually merchants, and then there were thousands of people who fled from the Western Regions.

There are people from all countries, of course, the largest number of people must be the people of Qiuci country, otherwise this city would not be named Qiuci City.

"Teacher, are there many countries in the Western Regions?"

Yan Yi is the most interested, his hometown is extremely far away from Chang'an, not to mention the more distant countries of the Western Regions.

"There are a lot of them, and I don't know the exact number, but there are at least ten, and if there are more, thirty is possible."

Who knew that there was a small city in that corner and a country.

ps At this time, there was no such thing as the Western Regions, and the Han people called the Western Regions the Northwest Kingdom during the period of Emperor Wu, saying that the Western Regions was to let more people understand this meaning.

The map in Zhang Yuan's hand recorded more than thirty countries in the Western Regions, but he didn't plan to be a person who knew everything.

Everyone in the group of people was convinced of what Zhang Yuan said, but there was a puzzle on Hong's face.

He didn't believe that Zhang Yuan didn't know how many countries there were in the Western Regions, and you had drawn a map of the world, and you still pretended not to know anything here.

"Let's go to the city, we have to keep a low profile on this trip.

If someone asks on the road, they will say that they are soldiers transferred from Fushi City. ”

"Yes."

Zhang Yuan did not inform the Governor of Qiuzi City in advance.

Entering the city also lit up Liu Che's edict, and did not let the guards at the city gate make a noise.

After the group entered the city, they didn't have time to see those people from the Western Regions in strange costumes, but went directly to the governor's mansion of the capital of the subject country.

There are too many captains and county guards in the Han Dynasty.

Moreover, most of these people could not be transferred back to Chang'an in their lifetime, so there was a gap between the local officials and the Beijing officials.

Even if the Beijing official is on the same level as the local official, he will feel superior.

What's more, Zhang Yuan is half a level higher than the captain of this subject country.

The students have a sense of superiority, but Zhang Yuan is smiling when he sees every border army.

Naturally, the governor's mansion in the border area is not as good as the county government in the rich land.

Zhang Yuan: What they saw in front of them was a courtyard made of loess tamped.

Except for a few soldiers guarding the door, there was nothing more peculiar about it.

"I'm the Taixue Order of the Great Han, and I want to see a subordinate lieutenant.

This is my seal, you can go in and spread it. ”

Zhang Yuan took his seal and handed it to the guards at the door.

Maybe there has never been such a big official in this place, or maybe this guard doesn't know what kind of official Taixue Ling is, the guard was more embarrassed and stunned at the door for a while, before he nodded and went in to report.

"Teacher, it seems that no outsiders have come to this place for a long time."

"Perhaps, these border troops have been stationed for more than ten years, and they may die of old age without the order of the imperial court.

It's normal to be a little more wooden than we thought. ”

In front of several other guards at the gate, Zhang Yuan began to tell everyone about the pain points of these border soldiers.

In fact, what Zhang Yuan wants is to arouse a kind of empathy, the students will all enter the army in the future, and an officer who understands his subordinates is much easier to mix in the army than a harsh general.

Of course, if you have a handsome talent or a general who is unparalleled in the world, you can let the soldiers below worship you.

Huo Quzhi's harsh criticism of the soldiers is basically the first in the Han Dynasty.

But there is still a group of soldiers who are willing to follow Huo Qubing to go on the expedition, and this strange phenomenon is not because of Huo Quzhi's outstanding ability.

Everyone knows that there is a good chance of going out to get military merit with Huo Quai, and as long as he doesn't commit suicide on the spot for the sake of military merit, it's okay to be harsh and suffer some hardships.

But Zhang Yuan felt that the students who studied too much did not have the hope of having a great talent in the army, since this is the case, it is better to honestly take the broad road of loving soldiers like children.

While Zhang Yuan was speaking, the guards who went to pass the word also came out.

He was also accompanied by several men in the armor of the general.

After the guards handed the seal ribbon to Zhang Yuan, the general led by him knew who was Taixueling.

"The last general has seen the Taixue Order."

"You're the city's vassal?"

"It's the last general."

Zhang Yuan looked this person up and down, he was the image of a normal general, with a look in his eyes, a fierce face, and even a scar on his face.

This lieutenant of the subject country must not have gone to Chang'an to see Liu Che, otherwise it would be impossible to sit down in this position.

Liu Che himself is not good-looking, but he is a face control.

In Liu Chena, the saying that appearance is justice makes sense.

"Let's go in first, and the lieutenant can have someone lead these people who have come with me to find a place to stay."

Zhang Yuan has Liu Che's edict in his hand, so naturally he doesn't need to be polite to the governor of this subject country.

Representing Liu Che outside, wouldn't it be a disgrace to His Majesty the Great Emperor if he whispered his breath.

"What is Taixue Ling's trip for?"

The lieutenant of the subject country didn't react at once, did Zhang Yuan want to be the master of this painting.

"Your Majesty has a secret order, this is not the place to speak, just do what I say.

You and I will find a quiet place, and I will explain it to you. ”

In the end, this sentence still worked, and the lieutenant of the subject country suddenly became serious.

"Do what Taixue says and entertain them."

"Whoa."
