The Tang Dynasty started from saving Empress Changsun

Chapter 268 A Bigger Shock

Li Tai was very surprised and said, "Are you willing to teach me?"

Chen Jingke said with a smile: "Why don't you want to, I am now looking forward to the emergence of 1 like-minded people, and I will study Gewu together and create more tools to change the world."

Li Tai said excitedly: "Okay, let's study Gewu together and change the world."

Li Chengqian praised: "I admire Jing Ke's heart."

Du He and others also said one after another: "Yes, like Sun Zhenzhen, I never cherish my broom, I feel ashamed."

Seeing my brother being praised, Xiao Si raised her head high, not to mention how happy she was.

In order to completely attract Li Tai, Chen Jingke took out two more small toys.

One is a temperature difference machine, as the name suggests, a power machine that can be started by using a temperature difference.

It's so small, it's about the size of a teacup when put together.Below is a piston-like structure with a wheel on it.

Pour a cup of hot water and put the thermostat on the cup, and use the temperature difference between the hot water and the air to drive the structure to rotate.

The principle is different from the steam engine, the former uses the power of steam, and the latter uses the power of temperature difference.

Everyone had just experienced the baptism of the phonograph, and although they were also surprised, they did not lose their composure.

The third is a miniature train, the size of a palm, and the whole body is made of copper.

Fill the water tank with hot water, ignite the alcohol fuel, and the train starts running along the track.

At the beginning, everyone didn't realize it. Isn't this thing similar to that temperature difference machine?Why make two more?
But this car is quite fun, it is a good toy.

then……

car?Now it was Li Chengqian's turn to pounce over, his eyes fixed on the little train.

Chen Jingke couldn't help nodding, yes, Li Chengqian's political acumen is still qualified, and he was the first to see the role of the train.

"Jing Ke...can this thing carry a load?"

Chen Jingke said affirmatively: "This object is called a train, and it was originally created to carry heavy loads. Enlarging the train and putting it on the car body is the best means of transportation."

Li Chengqian said excitedly: "Okay, it's really great. If we have this thing, our Tang army can quickly travel to any place in the world."

Du He also said excitedly: "Army rations consume [-] to [-]% on the road to transport grain and grass. If we have this fire...car, all these consumptions can be saved."

Everyone is from a wealthy background, and they have been sensitive to this aspect since they were young.After a little explanation, everyone knew the purpose of the train, and naturally they were very surprised and excited.

There are only two people who don't care much about trains. One is Princess Chengyang, who is only interested in gramophones.

One is a little Sizi, who has not yet reached the age of understanding.But it doesn't prevent her from knowing that her brother has created something extraordinary, which is a pride.

Chen Jingke poured cold water on everyone: "Everyone, don't be happy, 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 need to use at least [-] catties of steel."

"If the rails below are to carry trains and heavy loads, they must be made wider. A ten-meter rail requires a thousand kilograms of steel..."

"With the steel output of Datang, even the railway from Weishui Wharf to Chang'an City cannot be built."

"..." Everyone fell silent for a moment.

Datang's steel output at this time was only a little over one million catties, that is, about five or six hundred tons, and it was used in all aspects, so it really couldn't afford to repair the railway.

There is no historical record of steel production in the early Tang Dynasty, but according to Shihuo Zhi records, it was only about [-] tons at the peak of the Middle Tang Dynasty, and the production fluctuated greatly due to turmoil afterwards.

In the Song Dynasty, society was stable and smelting technology advanced, and the peak output of steel reached [-] tons.

In the early Tang Dynasty, the war had just ended and there was a lot of waste waiting to be built. The steel output was only five or six hundred tons at most. It really couldn't afford the railway.

Li Chengqian said unwillingly: "Is there no other way?"

Chen Jingke shook his head and said: "The construction of the railway is a big project. It may take several years or even more than ten years to repair a section of the railway. If it is destroyed in a few months, what's the point?"

"So the railway is a century-old project, and it was built with the intention of using it for a hundred years or even longer. There is absolutely no possibility of opportunism."

Li Chengqian felt very uncomfortable that the divine object was in front of him but could not be used.

What Chen Jingke wanted was this kind of effect, and added another fire: "Have you ever thought that putting a steam engine on a car can make a train, but what if you put it on a boat?"

"With the steam engine as the power, can we replace the wooden ship with a giant steel ship? By then, wherever our battleship is parked, it will be Datang's territory."

Li Chengqian said with a wry smile: "Don't talk about Jing Ke, you can't afford to build a train, let alone a steel warship."

Chen Jingke smiled and continued: "This is the greatness of Gewu, and why I say Gewu can change the world."

"Now it is difficult to make trains, but if we study Gewu and study more advanced mining and smelting technologies, one day we will be able to produce hundreds of millions of catties of iron every year."

"At that time, there will be endless railways on land, and giant steel ships in the rivers and seas. Who will be my opponent in the world?"

……

The party ended in such a hasty way. After being so shocked, everyone lost interest in chatting.

Before leaving, Li Chengqian wanted this miniature train, but Chen Jingke only gave him the temperature difference machine, and gave Xiao Sizi both the train and the gramophone.

Li Chengqian was a little dissatisfied at first, but immediately thought of the reason why he did this, and left with the temperature difference machine.

After finally seeing her brother leaving in a blink of an eye, Xiao Sizi was very unhappy, but she had a mission and couldn't do without leaving.

Chen Jingke repeatedly promised to go to the palace to see her when he was free, so he reluctantly left.

Li Tai, Cheng Huailiang, and Qin Huaidao stayed behind.

Li Tai was discussing the matter with him, while Cheng Huailiang and Qin Huaidao had other matters.

"We found dried shrimps, and we also found another thing called sea sausage. The meals made with them are indeed more delicious."

Cheng Huailiang introduced: "And they have a salty taste, and they can save a lot of salt."

Chen Jingke was not surprised, but just said: "That's good, since 'Dongfeng' is here, let's move on to the next step."

Cheng Huailiang said excitedly: "Okay, since I have nothing to do anyway, I plan to go to Luoyang and Zhenjiang to settle 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 monosodium glutamate to open all branches in Luoyang, Zhenjiang, Yangzhou and other important cities at once.

After discussing the details, Cheng Huailiang and his wife left.

Li Tai couldn't wait to run over to him for advice on Gewu.

……

Looking at the phonograph and the moving train in the palace, Li Shimin and Changsun Wugou were very shocked.

Then Li Shimin sighed and said, "Jing Ke is urging me."
