The heavens start from saving Daming

Chapter 749 I have studied chemistry!
Li Yunze once heard a saying that even a farmer could knock out a steam locomotive with a hammer.

He didn't know if the person who said this thought that the hammer in the farmer's hand was some kind of magical weapon, the kind that could get whatever he wanted with just one hammer blow.

Not to mention anything else, here in Da Qin, Li Yunze held hundreds or even thousands of drawings, gave instructions one by one, and taught step by step, but this group of craftsmen in the craftsmanship prison, who can be said to be the most capable craftsmen in this era, It still took more than a year to make a locomotive.

It is the kind of steam locomotive that has long been eliminated in the modern world, and even the small trains in the park are more advanced than it.

In order to reduce the technical difficulty, an ancient version of the technology was specifically found, with an average speed of only thirty or forty kilometers.

This also gave Li Yunze a stronger understanding of promoting mathematics, physics and chemistry.

I don’t even understand the basics, and I can’t knock it out even if I hit the drawing with a hammer.

Fortunately, a group of technicians have been initially trained, and they can carry out subsequent production according to the previous standards, so the work was not in vain.

In the past year or so, many things have happened here in Da Qin.

The most eye-catching among them was the rebellion of Chang'an Jun Chengyu.

After taking office, Ying Zheng immediately began to prepare to destroy the other countries. His first target was the State of Zhao, which he had once lived as a hostage.

When he was a hostage in Zhao State, Ying Zheng was bullied a lot, which left a heavy shadow.

Now that the army is in hand, of course they are going to take revenge.

Meng Ao set off with the vanguard and confronted Li Mu on the Qin-Zhao border.

Subsequently, Ying Zheng sent his younger brother Chang'an Jun with troops and horses to reinforce, but no one expected that halfway there, Chang'an Jun was actually persuaded by Fan Yuqi who was accompanying him to rebel directly.

The most direct consequence of Cheng Xi's rebellion was that Meng Ao was attacked from both sides and had his supply lines cut off. He was eventually defeated and killed by Li Mu.

The Qin army lost tens of thousands, and even many of the three-piece cavalry suits fell into the hands of the Zhao people.

Zhao Guo, who obtained the three-piece cavalry suit, felt like a treasure and quickly began to imitate it on a large scale. The combat effectiveness of his cavalry increased rapidly.

This is not the most deadly thing. The most deadly thing is that Cheng Yu also sent several of the King Qin cannons carried with the army to Zhao.

The propellant that all countries have been striving for has finally fallen into their hands.

Cheng Yu's rebellion brought great harm to Qin.

Fortunately, although Zhao Guo obtained the propellant package and knew its approximate ingredients, they did not know the specific proportions and production process.

Moreover, the quality of the artillery they cast themselves was very poor, and the barrels even exploded during test firing.

If you want to improve the smelting technology and figure out the propellant ratio and production process, you can't even think about it without a few years of effort.

When the news reached Xianyang City, Ying Zheng went into a state of rage.

Then a large number of Qin troops rushed over like a tide, trapping Cheng Yu's rebels within the Tunliu Barrier.

Li Mu once led his troops to rescue, but facing the Qin army's tide, he had no choice but to retreat.

However, when retreating, Fan Yuqi, who broke out of the encirclement, was accidentally rescued.

As for Cheng Xi, he chose to commit suicide out of despair.

In order to vent his anger, Ying Zheng, who was furious in history, not only executed all tens of thousands of Cheng Xi's subordinates, but even sent all the people in his fiefdom to do hard labor until they died.

This time, Li Yunze took the initiative to go to Xianyang City and persuaded Ying Zheng to only kill the top culprits, that is, those with a hundred generals and above, and those with titles above five officials.

The remaining sergeants were all sent to Li Yunze to work here to build the railway.

As for the people who were said to be on the land, they were punished by being forced to work as corvees. Their job was also to build railways.

After nearly a year of construction, the railway laying with little technical content has been very smooth. It has been laid from Yueyang to Jincheng (Lanzhou), and across the river is the Hexi Corridor.

In order to support this project, Qin State was mining everywhere, digging iron ore, coal and then smelting it to make railroad tracks.

When envoys from various Eastern countries came to Qin, what they saw was that the Qin people did not build the Great Wall or tombs during their leisure time, but instead worked hard to mine.

On the road leading to Xianyang City, towering indigenous blast furnaces can be seen everywhere.

Thick black smoke and yellow smoke covered the sky and the sun, and the blazing fire seemed to ignite the world at night.

The countries in Kanto were all frightened and at a loss. They had no idea where the Qin people's terrible productivity came from.

After Li Yunze got the locomotive here and came out, he went to Xianyang City to find Ying Zheng to visit. At the same time, he went to visit the Queen Mother and send him to learn from the experience.

Ying Zheng is also very interested in this kind of steel giant that can move on its own, thinking that with this thing, it will be enough to run rampant in the world.

So after arranging all the work, I came to Yueyang with Li Yunze in high spirits.

Even though he had seen the drawings many times and even the wooden models were placed in Xianyang Palace, when Ying Zheng saw with his own eyes that the length was nearly ten feet, the height was nearly two feet, and the width was about ten feet, the whole body was made of steel. It is said that When I saw the actual object weighing hundreds of thousands of kilograms, I was still shocked and speechless.

I walked around the front of the car a few times and stretched out my hand to touch it for a long time.

Ying Zheng, who had finally calmed down, rushed to Li Yunze with an ecstatic expression, grabbed his hand and shouted, "Master, if you have such a divine object in your hand, where in the world can you go? When conquering other countries, just take this The iron beast is sent to the battlefield and rushes straight over."

"Your Majesty."

Although it was said that it was impolite to interrupt others, Li Yunze still corrected Ying Zheng's cognitive error, "Have you forgotten that this thing can only run on railroad tracks?"

"Uh~~~"

Ying Zheng was stunned for a moment, "I remember that I heard the Taifu say that steel monsters can also run on the ground."

"That thing is called a tank." Li Yunze shook his head repeatedly. "It requires technological breakthroughs in internal combustion engines and miniaturization, as well as the supporting equipment of the petroleum industry. With Daqin's current technological level, even if it continues to develop along the path of mathematics and physics, it will take another few hundred years. Let's do it." It's not that a steam engine tank can't be made, but it's actually because it would be pointless even if it were made.

Production, maintenance, transportation, use, etc. are all very troublesome, and the speed cannot even keep up with the running of sergeants.

Now that we have powerful cavalry, there is no need for steam engines and tanks.

As for internal combustion engine tanks, Li Yunze estimates that it will take at least 200 years.

We still have to go all out on the technological side and not let Confucianism and Buddhism take the lead, or even those who only talk about the nature of mind but not practice.

After listening to Li Yunze's words, Ying Zheng immediately looked disappointed, and the previous excitement disappeared.

"Don't think so much." Li Yunze patted his shoulder and reassured him, "One generation does one thing. What you have to do now is to lay a solid foundation for science, just like what the previous Qin kings did. Only the predecessors By continuously accumulating, future generations will have the opportunity to make a lasting contribution.”

The specially trained driver got on the front of the car, lit the stove and started shoveling coal into the stove.

Just starting it up takes a lot of time.

When the soft water in the water tank is finally heated and the steam in the valve begins to overflow, the powerful steam force finally begins to push the piston to reciprocate, releasing energy through equipment such as connecting shafts, gears, connecting rods, etc.

The moving structure pushed the huge wheels to start rotating. Amidst the rumbling sound of steel friction, this behemoth finally started to move.

"It's moving, it's moving! It can actually move!"

Ying Zheng's mood became aroused again.

'Dirty dirty dirty~~~'

Steam rushed out through the whistle tube, making a shrill sound. The shocking sound and the movement of the steel giant scared many people around with their hands and feet weak, and they collapsed on the ground trembling.

There were also people who knelt down and worshiped the front of the car, muttering something in their mouths and not knowing what they were talking about.

Seeing this scene, Li Yunze didn't say much, nor would he laugh at these people for being so ignorant.

He just put his arm around Ying Zheng's shoulders and warned him, "People who study science can build such huge beasts and make them move. This is the power of science. People who have not studied it will only think that it is You can't walk on these magical things, let alone control them. Now tell me, is science important?"

"What the Master said is very true!"

Ying Zheng nodded vigorously, "I believe in science and can control such a giant steel beast. Ignorant people don't understand and don't believe it. They are behind the times."

Li Yunze smiled and nodded, then waved his hand to the driver to pull the brakes and stop the car.

After that, he and Ying Zheng and others got into the car at the back.

"The carriage is much simpler to build." After getting on the carriage, the first thing Li Yunze did was to close all the doors and windows. "The most critical thing is the frame structure. Once this problem is solved, the technical difficulty of the carriage will be no more than that of a carriage." the difference."

The locomotive moved forward again, driving the carriages under its feet to rumble.

The excited Ying Zheng responded and hurriedly opened the window to see the scenery outside.

But as soon as the window was opened, a pungent smoke rolled in, choking Ying Zheng and coughing repeatedly.

Li Yunze shrugged. He had experienced this kind of thing once.

The locomotive drove hundreds of miles in one go before slowly stopping.

Ying Zheng came out of the carriage and looked at the surrounding environment and took a deep breath: "Master, I want to build this railway track out of Hangu Pass and spread it to other countries. Wherever the railway track is built, the army of Great Qin will follow!"

Ying Zheng, who likes big projects, started his own new project.

When he returned to Xianyang City happily, Zhao Gao came to report, "Your Majesty, there are several alchemists who brought elixirs from overseas fairy mountains and wanted to offer them to your Majesty."

"Heh~~~"

Upon hearing this, Ying Zheng sneered and said, "Let them in."

The alchemists have good looks and natural demeanor. They are not nervous about meeting the king at all, and they look like they have a fairy-like temperament.

After the salute, the leader came forward and said, "As the King of Good Teaching knows, we went out to sea to find the Immortal Mountain and visited the immortals on the Immortal Mountain. We were enlightened and blessed by the immortals, and were given the elixir to prolong life."

"We know that we are not blessed to enjoy such immortal things, so we came to Xianyang City specially to offer them to your Majesty."

"Oh?"

Ying Zheng, who looked calm, said calmly, "Take it and take a look."

The alchemist took out a delicate small box from his arms and carefully handed it into Zhao Gao's hands.

The checked box was placed in front of Ying Zheng.

He looked at the red pill in front of him, reached for it, put it in front of his nose, smelled it, looked at it, and even pinched a piece for analysis.

"This smell and this color include lead, mercury, and sulfur, which is mercury sulfide. Realgar, alum, Zeng Qing, Ci Shi, I have studied chemistry!"

Ying Zheng casually put the so-called elixir back into the box. Ying Zheng stared at the alchemist below, "What's your name?"

"Back to your Majesty, I am nothing more than a wandering cloud wild crane, and my name is nothing more than."

"I asked you what your name is!"

Ying Zheng roared, which frightened the alchemist who was still pretending to beep. He trembled and responded hurriedly, "Go back to your Majesty, my name is Xu Fu."
