Liu Yuan inspected every piece of dry land on the mountain and found that the crops on the dry land on the mountain were not inferior to the crops in the water land.

Li Tai said proudly: "Liu Siqing, how is it?" The hydraulic waterway researched by this king is good! ”

Liu Yuan nodded firmly: "Of course it's a very important invention, but ...... His Royal Highness King Wei, there is a lot of land in the world, but not all places have a river to borrow! ”

Li Tai's laughter stopped, and he also began to worry, yes, there are so many places under the sky, not necessarily there are turbulent rivers at the foot of every mountain, if there is no turbulent flowing water to power the waterwheel, how can water be delivered?

"Also, this water-powered waterway can bring water to the mountains without manpower, but what if the mountains are far away from the water? The waterways are paved with wooden planks, and not every farm has so many carpenters! ”

The smile on the corner of Li Tai's mouth disappeared completely, which ...... That's a big problem!

Liu Yuan saw that Li Tai was sluggish, so he changed his words and said: "However, this kind of invention is already very good, and King Wei doesn't have to mind it so much." ”

"Liu Siqing, do you think this king will mind?"

Li Tai, who had been languishing for a while, suddenly raised his head again: "Master said that physics is first familiar with the characteristics of objects, so that people can seek advantages and avoid disadvantages, and later it is to accept all things for their own use!" There are many rivers in the world, but dare you say that there is a place where there is no wind?

Does this king have to use running water as a power source? The plank waterway pushes the water and does waste wood, but the hemp rope is something that every family has, hahahaha......"

Li Tai walked away laughing with his hands behind his back!

Liu Yuan was a little confused, wind? What does it have to do with following the trend?

Li Chengqian thought about it, and suddenly patted his head: "Windmill!" ”

Li Ke also understood: "It's the fast toy that blows in the wind?" Qingque's brain is so good! ”

Liu Yuan thought about it for a while, and he had to admire King Wei's exquisite heart......

Just as Li Tai was drawing and studying the wind, Yan Liben came in.

"His Royal Highness King Wei, what are you studying?"

Li Tai was overjoyed when he saw Yan Liben, among the people he knew, only Yan Liben gave him a feeling of "confidant", and when he studied the water power channel, he and Yan Liben often had the same idea.

Li Tai said: "Liu Yuan, the secretary of Sinong Temple, said that the hydraulic waterway we studied is useless without the turbulent river, and also said that the wooden waterway is time-consuming, laborious and labor-intensive, and the people can't afford it."

Hum! This king will study this and show it to him! ”

After speaking, Li Tai picked up the windmill on the table and blew on the windmill, and the windmill squeaked and turned.

Yan Liben and Li Tai's tacit understanding had long surpassed that of Wolf and Embarrassment, and when he saw this scene, he opened his mouth directly: "Windmill? Borrowing wind power? ”

Li Tai knew that Yan Li instinctively saw it at a glance, and said with a smile: "It's worthy of you, you can see it at a glance!" What do you think? Study windmills with Ben Wang? ”

Yan Liben shook his head: "No, now I am assigned by your master to study the use of water to pull the hammer up and down to help the blacksmith strike iron, and today I already have a clue." Lord Wang, you might as well follow me to study the hydraulic hammer first! Let's study the windmill together after it is formed! ”

As long as there is something to study, Li Tai is happy, and he, like Yan Liben, is a person with a strong desire for knowledge. Doing things like hacking and sawing wood drives them crazy, and they only get ecstatic when they study something that no one else has ever seen.

Research maniacs are like this, and when they study deeply, they will leave it behind even if they drink water, eat and sleep.

Oh no, the meal item doesn't include Li Tai.

As soon as the meal arrived at noon, Li Tai hurriedly entered the restaurant.

Leng Feng persuaded Liu Shuwen to believe that he was fine, and the big crab sent by Li Shimin was a waste for the chef to make it!

Crabs are such a thing, there are few people in Guanzhong who like to eat them, they are covered in shells, and there is not much meat, just like Cao Cao eats chicken ribs, and it is a pity that his index finger is abandoned without meat.

But the crabs in the sea are different! The size of three or four can make people eat and the scum of river crabs is simply one in the sky and one on the earth.

These big crabs were sent by the seaside thorn history to the emperor to pay tribute, even if the water has been changed, but after the toss of the waterway, these crabs do not survive.

Steamed! Must be steamed! After the crab meat is steamed, it is simply delicious when it is dipped in seasoning dipping sauces such as rice wine vinegar, and it is more than delicious compared to the idiot practice of the imperial chef who takes out the crab meat and stews it in soup.

Ten big crabs were wiped out by five people, and Li Tai licked off the last trace of crab meat on the carapace and said with emotion: "It's a pity, this rare delicacy is still too little, and I haven't eaten enough to my heart's content." ”

Leng Feng pointed at Li Tai with a crab leg and said to Li Ke: "Look, why don't you eat minced meat!" ”

Li Ke pulled the corner of his brother's coat and said, "Qingque, there are many of these big crabs on the seashore, just like the birds on our mountain. It's just that the sea is too far away from Chang'an, and you can only take the waterway, so you will cherish it so much. When we go to attack Goryeo, the third brother will take you to the beach to eat enough! ”

"Really? There are as many things on the beach as there are birds? ”

The saliva at the corner of Li Tai's mouth flowed down and he didn't know it......

The sea is second only to the Yama Hall to the Tang people, and countless maritime merchants who go to sea and die in shipwrecks every year.

Even after the emergence of steamships thousands of years later, shipwrecks are still occurring one after another, not to mention the current era when ship materials are all wood?

Steamship...... Without rubber as a sealing material, the steam engine became a steam machine, rubber originated in the Americas, but now that sea ships cannot cross the ocean, they can only ponder through the Bering Strait. (between Russia and the continental U.S.)

If you want to pass through the place where you are about to reach the Arctic Circle, cold protection is indispensable, and cotton is also needed to protect against the cold.

Cotton is now planted in Gaochang, but the people of Gaochang are very hateful, cotton can be sold, but cottonseeds are not given!

Li Shimin also hates this neighbor who is ready to move several times.

Wei Chigong's battle report was thrown aside by Li Shimin.

Tubo is strong, and it is just their aggression, and you Gaochang is a small country that dares to be so presumptuous!

Opening the inventory account book of the Thunderbolt Division, Li Shimin looked at the numbers on it and felt very uncomfortable, couldn't it be faster?

Yes!

Yan Liben took the last mechanism, and the power of the waterwheel from the flowing water immediately began to be transmitted, and after the connection, moment group, and pulley group, the big iron pillar that needed more than a dozen strong men to lift moved up and down!

Boom! Boom!

The iron pillar began to smash the iron plate below, and it seemed to be full of force!

The chapter posted in the morning said that it exploded today...... I was going to release two chapters at noon, but ...... The drafts saved locally are gone, and the phone is inexplicably deleted...... Haematemesis......
