Datang: God-level son-in-law, salted fish will become stronger

Ugh......

Qin Mu sighed helplessly, and continued: "Then I will give you another example." Immediately afterwards, he turned his head to look at Liu Renyuan, and said, "General Liu, let me ask you a question."

Hearing this, Liu Renyuan nodded, "It doesn't matter, my son-in-law."

Qin Mu asked: "You are a navy general, you know, if you stand on the shore and look at the ships in the sea, will the ships disappear when they travel a certain distance?"

Liu Renyuan thought about it for a while, and replied: "Of course."

Li Er's face was gloomy, and he pondered: "This is all nonsense, it's beyond sight, and it will disappear."

Qin Mu: ...

He stood up, "Your Majesty, tell me! Tell me what the world looks like."

"Hehe..." Li Er smiled awkwardly, "You come, you come, I just have a little bit of doubt."

Qin Mu glanced at him, and continued: "In the sea, the ship goes away and gradually disappears on the horizon. First, the hull disappears, and finally the mast disappears. If the earth is flat, how could such a thing happen? It should be The ship and the mast should disappear together."

"In this way, the world must be round."

The words fall.

Everyone was silent, thinking secretly in their hearts, imagining the picture in their eyes.

moment.

Liu Renyuan was the first to react and suddenly realized.

hmm~

It really is!

"My son-in-law, I feel that what you said is very reasonable. The world must be round. It is true that the hull disappears first, and the mast disappears last. If the world is flat, it should indeed disappear together, and it shouldn't disappear suddenly. , but become a small black dot."

As Liu Renyuan spoke, his eyes were filled with amazement.

Everyone in the hall was also amazed.

This is too exaggerated!

The son-in-law can infer that the world is round by virtue of the fact that the hull disappears first and the mast disappears after the boat is on the sea.

And that crescent moon makes sense too!

The sun is round, the moon is round, so the earth is not flat after all!

At this time, Li Er and all the ministers felt that Qin Mu had subverted their three views.

This is something beyond their cognition.

Followed by.

Li Er continued to ask: "Then I will ask you again, even if the world is really round, wouldn't the people on the other side fall into the sky?"

The words fall.

Everyone looked at Qin Mu with burning eyes, full of curiosity.

Qin Mu: ...

It's really fucking off the charts.

These people are addicted to science and knowledge!

Qin Mu saw that he couldn't hide, so he explained.

"I can only give you a general idea, and that's because of gravity."

"It's this attraction of the land to other objects, called gravity."

"That's why everything falls to the ground, no matter how much you jump you have to fall to the ground."

Li Er wondered: "Then why can birds fly into the air?"

Qin Mu said helplessly, "Then why don't you let it not flap its wings?"

Li Er: ...

Although everyone is still in the fog and hear only a half-knowledge, they have a general understanding after all.

Liu Ren is willing to return from a long voyage, maybe it can really confirm this conjecture.

If so, maybe the map of the son-in-law is reliable.

Everyone couldn't help looking at the globe again, and it turned out that their world looked like this.

"Okay." Li Erdai nodded, "Since that's the case, Liu Ren would like to give you the ball, so that you may have a direction."

Liu Renyuan hugged the globe happily, "Thank you Your Majesty for the reward, thank you Prince Consort for the reward."

Liu Renyuan was really happy.

Afterwards, everyone discussed some details and the meeting ended.

Qin Mu went to the Qin Mansion very tiredly.

Today is really tired enough.

It was enough to even give them a lively science lesson.

......

ten days later.

Liu Ren is willing to lead a team to leave Chang'an City and go straight to Laizhou, ready to set off on a great voyage.

Sunflower and spring bud milk tea shops have also spread all over cities and counties in Gyeonggi-do.

There is one more thing to be thankful for.

That is, Li Er's billiard hall has opened, and the business is booming.

There are ten stores in Chang'an City.

Li Er was very happy about this matter. After all, this was the way he came up with to make money.

Zhenguan ninth year, mid-September.

Due to the heavy rain in Duji Province, the water of the Yellow River soared and the river flooded.

The imperial court responded in advance, evacuated the people, and repaired the embankment, and the effect was remarkable.

However, the river in Shanzhou broke its embankment, and several counties that had no time to evacuate were hit by floods.

Fortunately, the imperial court was well prepared, and the damage caused by the flooding of the Yellow River was not very great, only these counties were hit.

Chang'an City.

Moderate rain.

Qin Mansion.

Qin Mu was playing with Tang'er in the living room.

Wang Xuance and Xue Rengui came to the hall, "My son-in-law, Your Majesty is waiting for you outside the mansion."

Qin Mu frowned, and asked doubtfully, "Wait for me? What are you waiting for? It's a rainy day, what the hell is your Majesty trying to do?"

Wang Xuance said: "Isn't it true that several counties in Shanzhou have been flooded? Your Majesty wants to visit Weifu privately."

Qin Mu: ...

He saw that Li Er really had nothing to do, so he even made a private visit in a micro-service! ?

Qin Mu said indifferently: "Just tell your majesty that I have caught the cold and should not go out."

Qin Mu has really given in to Li Er, because he is relying on him, and will bother him when he is in a hurry.

If you are willing to visit privately via Weibo, you can go.

Shanzhou is not far away.

The voice just fell.

Li Er came in from outside the hall wearing a coir raincoat, "Is the son-in-law caught in the wind and cold? Let me see if it's serious or not?"

Qin Mu: ...

Why is this still blocking the door?Do you want to show some face?

Are you the sixth child?

Chapter 1263

hall.

Seeing Li Er coming, Tang'er was very happy, and ran over joyfully, "Grandpa, have you come to play with Tang'er?"

Li Er tore off his coir raincoat, hugged Tang'er, said with a smile, "That's right, grandpa came to play with you, do you miss grandpa?"

"I miss Grandpa." Tang'er said with a smile, staring at her eyes like autumn water.

Immediately afterwards, Li Er looked at Qin Mu and pondered, "Let's go, son-in-law? Several counties in Shanzhou have suffered disasters. Don't you always want to promote the renovation of houses in the Tang Dynasty? This time your chance has come."

Qin Mu frowned slightly, and said quietly: "Your Majesty, isn't that what you always want to implement?"

"Tsk..." Li Er glared at him, and said in a deep voice, "Is there any difference between what I want to promote and what you want to promote? It's not like I don't want to pay."

Nowadays, the cement manufacturing technology, brick firing technology, metallurgy technology and glass technology in Mangya Industrial Zone are very mature.

So Qin Mu once drew a blueprint of a concrete house, which happened to be seen by Li Er.

Li Er couldn't put it down after seeing it, and he couldn't stop, and he always thought about this matter in his heart. If the people of the Tang Dynasty could live in such a house, it would be the real prosperity of the Tang Dynasty.

This time Shanzhou was hit by a disaster, and it was very close to Chang'an City, so Li Er thought about going to see it, and put this matter on the agenda.

What Li Er is currently pursuing is the prosperity of the Tang Dynasty, and he has no other desires.

"Okay." Qin Mu nodded helplessly, "Since His Majesty insists on this, then I will accompany you."

What Li Er said is a great thing that benefits the country and the people, Qin Mu can't just sit idly by.

Hearing this, a smile appeared on Li Er's face, "Haha, that's right, what's the fun in being bored in the Qin Mansion all day, this year we don't have far to go."

Soon.

Qin Mu, Li Er and a party of six, wearing coir raincoats, left Chang'an City and headed for Shanzhou in the southeast.

It is now September, and the weather is getting cooler after several heavy rains.

Due to rain.

The official road is very deserted.

Li Er rode his horse on the cement pipe, full of emotion.

In the end, it was the son-in-law who developed such a good thing, which greatly improved the traffic in the Tang Dynasty. Otherwise, with such heavy rain, the official road might not be able to go.

Nowadays, there are cement roads, which are undoubtedly like walking on flat ground.

Two days later.

The boundary of Shanzhou.

Hebei County.

The people were all moved to a distant hilltop.

The local county government and the Shanzhou Army set up temporary camps for the people.

There are also some soldiers searching for missing people.

Li Er, Qin Mu and the others came to the boundary of Hebei County. At this time, the heavy rain had already ended and the water level was dropping, but the water on the official road was still as deep as the horse's calf.

Every time he saw this situation, Li Er's heart was very heavy. He felt that his emperor was not doing enough.

at the same time.

A cavalry came running towards him.

"Quick! Hurry up!"

"There is a village on the west side of the mountain that was on the way to evacuate. There was a mudslide and the mountain road was blocked. Hurry up and save people!"

The leading general shouted loudly while riding his horse.
