Li Tai was greatly surprised and said, "Are you willing to teach me?"
Chen Jingke smiled and said: "Why don't you want to? I am now eager for 110,000 like-minded people to appear, study the study of objects with me, and create more tools to transform the world."
Li Tai said excitedly: "Okay, let's study the investigation of things together and transform the world."
Li Chengqian praised: "I admire Jing Ke's broadmindedness."
Du He and others also said: "Yes, just like Master Sun, I never take pride in myself. I am ashamed of myself."
Seeing her brother being praised, little Sizi raised his head high, not to mention how happy he was.
In order to completely attract Li Tai, Chen Jingke took out two more small toys.
One is a temperature difference machine, which as the name suggests is a power machine that can be started by using temperature differences.
It is very small, and the whole thing is about the size of a tea cup. The bottom is a piston-like structure with a wheel on top.
Pour a cup of hot water and place the thermometer on the cup. Using the temperature difference between the hot water and the air, you can push the structure to rotate.
The principle is different from that of a steam engine. The former uses the power of steam, while the latter uses the power of temperature difference.
Everyone had just experienced the baptism of the gramophone. Although they were surprised, they did not lose their composure.
The third item is a mini train, about the size of a palm, made entirely of copper.
Fill the water tank with hot water, ignite the alcohol fuel, and the train starts running along the track smoothly.
At first, everyone didn’t realize it. Isn’t this thing similar to the thermometer? Why build two more?
But this car is quite fun and a good toy.
Then……
Car? Now it was Li Chengqian's turn to rush over, his eyes fixed on the little train.
Chen Jingke couldn't help but nod, yes, Li Chengqian's political acumen was still qualified, and he was the first to see the role of the train.
"Jing Ke...maybe this thing can carry a heavy load?"
Chen Jingke affirmed: "This thing is called a train. It was originally created to carry heavy loads. Enlarging the train and putting a carriage on the back is the best means of transportation."
Li Chengqian said excitedly: "Okay, it's really great. If we have this thing, our army of the Tang Dynasty can quickly reach anywhere in the world."
Du He also said excitedly: "Military rations, transporting grain and grass consume 80% to 90% on the road. If we have this fire... vehicle, these consumptions can be saved."
Everyone was born in a powerful family, and they have been sensitive to this aspect since they were young. After a brief explanation, they all knew the purpose of the train, and naturally they were very surprised and excited.
There were only two people who didn't care much about trains. One was Princess Chengyang, who was only interested in the gramophone.
One is a little Sizi, who has not yet reached the age to understand. But it does not prevent her from knowing that her brother has created something incredible again, which is called pride.
Chen Jingke poured cold water on everyone and said: "Don't be happy, everyone. This thing requires a lot of steel, and it must be high-quality steel."
"I have calculated that if you want to build a locomotive that can drag heavy objects, you will need to use at least 100,000 kilograms of steel."
"If the rails below want to carry trains and heavy objects, they must be made wider. A ten-meter rail requires thousands of kilograms of steel..."
"With Datang's steel production, we can't even build the railway from the Weishui Pier to Chang'an City."
"..." Everyone fell silent for a moment.
At this time, the steel output of the Tang Dynasty was only a little over one million kilograms, which is about five or six hundred tons. It was used in all aspects, and it really couldn't afford to build railways.
There is no historical record of steel production in the early Tang Dynasty, but according to records of food and goods, it was only about 1,000 tons at its peak in the middle Tang Dynasty. After that, the production fluctuated greatly due to turmoil.
By the time of the Song Dynasty, social stability and smelting technology had progressed, and peak steel production reached 4,000 tons.
The war in the early Tang Dynasty had just ended, and everything was in ruins. The steel production was only 500 to 600 tons at most, and it was really impossible to build a railway.
Li Chengqian said unwillingly: "Is there no other way?"
Chen Jingke shook his head and said: "The construction of railways is a big project. A section of railway may take several years or even more than ten years to repair. If it is damaged after a few months, what's the point?"
"So the railway is a century-old project, built to last a hundred years or even longer. There is absolutely no possibility of opportunism."
Li Chengqian felt very uncomfortable when the divine object was right in front of him but he couldn't use it.
Chen Jingke wanted this effect, and added a touch of fire: "Have you ever thought that you can make a train by putting a steam engine on a car? What if you put it on a ship?"
"With steam engines as power, can we replace wooden ships with giant steel ships? Wherever our warships park then will be the territory of the Tang Dynasty."
Li Chengqian smiled bitterly and said: "Jing Ke, stop talking, we can't build a train, let alone a steel warship."
Chen Jingke smiled and continued: "This is the greatness of studying things, and this is why I say studying things can change the world."
"It seems difficult to make trains now, but if we study gewu and more advanced mining and smelting technology, one day we will be able to produce hundreds of millions of kilograms of iron every year."
"At that time, there will be endless railways on the land and giant steel ships in the rivers and seas. Looking at the world, who will be my opponent of the Tang Dynasty?"
…
The party ended hastily. After receiving such a big impact, everyone lost interest in chatting.
Before leaving, Li Chengqian wanted this mini train, but Chen Jingke only gave him a thermometer, while the train and phonograph were given to Xiao Sizi.
Li Chengqian was a little dissatisfied at first, but he immediately thought of the reason why he did this, and left with the thermometer.
Xiao Sizi was not happy to see her brother leaving in the blink of an eye, but she had a mission and couldn't leave without leaving.
Chen Jingke repeatedly promised to come to the palace to see her when he was free, so he reluctantly left.
Li Tai, Cheng Huailiang, and Qin Huaidao stayed.
Li Tai wanted to discuss things with him, while Cheng Huailiang and Qin Huaidao had other matters.
"We found shrimps, and we also found another thing called sea sausage. The meals made with them are indeed more delicious."
Cheng Huailiang said: "And they have a salty taste, so you can save a lot of salt."
Chen Jingke was not surprised and just said: "That's good. Now that Dongfeng has arrived, let's make the next plan."
Cheng Huailiang said excitedly: "Okay, I have nothing to do anyway, so I plan to go to Luoyang and Zhenjiang myself to finalize this matter."
Chen Jingke said: "Thank you for your hard work."
Naturally, their next plan is to expand. This time they will take advantage of the opportunity brought by the local MSG to open branches in Luoyang, Zhenjiang, Yangzhou and other important towns at once.
After discussing the details, Cheng Hualiang and the two left.
Li Tai couldn't wait to run over to him to ask for advice on studying objects.
…
In the palace, Li Shimin and Changsun Wugou were very shocked when they saw the gramophone and the running train.
Then Li Shimin sighed and said, "Jing Ke is urging me."
