Li Zhi, don't be a coward

Chapter 489

Couples don't have to have common topics in the same field.

When Li Qinzai talked about physics knowledge, Cui Jie couldn't understand at all, but if Cui Jie talked about embroidery work with Li Qinzai, would he understand?

Each has made achievements, each has its own safety, husband and wife are not business partners, there is no need to maintain common ground on the topic of work, as long as the other party is exhausted, it is enough to pat the dust off his body.

The meal was eaten very slowly, the candlesticks stood in the middle of the table, the husband and wife laughed and laughed, it was a bit like a romantic candlelight dinner.

The atmosphere is so hot here, after dinner, of course we should do something we like, in the kitchen, in the wing room, on the bed, on the futon, by the well...

Um?It seems to be in some strange place...

Unfortunately, Li Qinzai did nothing after the meal.

Cui Jie's aunt is still in love, and Li Qinzai can't do anything about running a red light.

Fortunately, Cui Jie still has dexterous hands and feet, as well as attractive red lips, pink mantle and red tent, beautiful spring scenery, bone-destroying ecstasy, so there is no need to fill in the details...

The moment before he was about to tremble, Li Qinzai suddenly understood why men also like mermaids, how could An not be happy about this situation?
…………

The next morning, after Li Qinzai woke up, he sorted out the blueprints, and then ordered Buqu Kuaima to go to Chang'an City, and invited several skilled blacksmiths to come.

When Liu Ah Si heard about such a large amount of purchases, his expression immediately tightened. He knew that Wu Shaolang must make a big move, so he didn't dare to neglect, and galloped towards Chang'an City himself on horseback.

In addition to completing Wu Shaolang's mission to the letter, Liu Ah Si must also report the truth to the old man.

Wu Shaolang wanted to create new gadgets, and the entire Duke's Mansion attached great importance to it. Li Ji had already ordered him to know about it as soon as possible.

In the afternoon, more than a dozen blacksmiths came to Ganjing Village in Li's carriage.

But Liu Ahsi hadn't come back yet, and the task of purchasing [-] jin of pig iron was too huge to be completed in one day.

Interestingly, after Liu Asi reported the truth to Li Ji, Li Zhi of the Taiji Palace also knew that Li Qinzai was going to make something new. Not only did he personally order the blacksmiths of the military supervisor, but he also asked the inner government to send ten thousand catties of pig iron overnight. Go to Ganjingzhuang.

Most of the blacksmiths of the Military Weapons Supervision were from the army, and they had the temperament of a soldier. They stood in front of Li Qinzai in unison, clasped their fists solemnly, and asked Li Qinzai for orders.

Li Qinzai scratched his head, the battle was a bit big, it was just a hydraulic press, there was no need to be so grand, as if the building was about to fall, and he was the only savior.

Thinking that both his grandfather and Li Zhi attached so much importance to his creation of new things, Li Qinzai was still a little moved.

It feels really good to be valued and needed.

Unfolding the drawings in his hand, Li Qinzai pointed to the drawings and explained one by one.

Blacksmiths don't know hydraulic presses at all, but they know how to forge iron.

It is enough to know what kind of object Li Qinzai needs to make. As for what this object is used for, the blacksmiths don't know, and dare not know.

A complete hydraulic press requires a high-pressure water pump and a liquid-filled cylinder, as well as a large iron tank for water storage. However, in this backward age when the industry was almost blank, the high-pressure water pump and the liquid-filled cylinder were a bit difficult.

So Li Qinzai decided to build a crude hydraulic press, keeping only the key parts such as the large iron cylinder, iron ingot, anvil, and piston. The effect of water, and a water injection port is required above the iron cylinder.

The gravity generated by the weight of the water is used to increase the kinetic energy of the piston and the iron ingot, and then two sets of pulleys are used. After the iron ingot falls, the pulley block is used to raise the iron ingot, and then it is knocked down again.In this way, the effect of hydraulic forging can be achieved.

After Li Qinzai's detailed explanation, the blacksmiths finally understood what kind of parts Li Qinzai needed, so they geared up one by one, expressing that they would make what he needed as soon as possible.

The pig iron was transported to Ganjingzhuang that night. Li Zhi obviously attached great importance to it, and actually sent a team of Habayashi Imperial Guards to escort it.

Early the next morning, Li Qinzai came to the reservoir. The reservoir was basically completed. Li Qinzai ordered a water injection port to be connected to the bottom of the reservoir, and then used a treadmill to introduce Wei River water into the reservoir.

On the other side, the blacksmiths have temporarily built a row of simple sheds under the reservoir, and the furnace has been set up, and the pig iron is being hammered into steel.

More than a dozen blacksmiths were in full swing, and the shed was already full of people. The farmers didn't even do their work, and surrounded the blacksmiths curiously, whispering about what new gadget Wu Shaolang was going to build this time.

In front of the crowd, the students of the school stood in front of the blacksmith as a matter of course, observing them openly and asking questions to Li Qinzai from time to time.

The crude version of the large iron vat has begun to take shape, and the huge iron vat completely occupies the space of the shed. The students looked at this new thing that had never been seen with curiosity, and their expressions became more and more impatient, and they really wanted to see it. until it is fully formed.

Li Qinzai was also quietly watching the blacksmiths working, and said to the students indifferently: "Do you remember what I said? Arithmetic is just a tool, and it ultimately serves physics."

The students nodded one after another.

Li Qinzai said again: "Today I will let you see what 'physics' is all about, and why I say it can change the world."

The students nodded again. In the crowd, Princess Xuancheng's eyes were shining brightly, her expression was excited but suppressed, and she kept rubbing the corners of her clothes with restless little hands, obviously very excited inside.

Li Qinzai opened a window for her life. Today, she wants to stand on tiptoe and see what kind of world is outside the window.

She is about to see.

Beating again and again, the impurities in the pig iron were separated, and the iron block gradually formed.

Two hours later, a large iron ingot made strictly according to the size set by Li Qinzai was finalized under the hammers of the blacksmiths.

Next, build pistons and drains. Under the reservoir, farmers are installing pulley blocks, and the atmosphere of each performing their duties is very comfortable.

The students also came forward to help one after another. It is easy to do things with more people, and the efficiency is fast.By the afternoon, all the parts Li Qinzai needed had been built.

Li Qinzai directed the farmers to work together to install the big iron tank under the reservoir, and used a pulley block to install the big iron ingot under the big iron tank. The iron ingot and the iron tank were connected by a piston, and the inner wall of the iron tank was lubricated with grease.

Soon, a primitive and crude version of the hydraulic press finally took shape.

Li Qinzai looked at the hydraulic machine standing under the reservoir with satisfaction, and finally ordered people to install the water injection port and drainage channel.

Following Li Qinzai's order, the water from the water injection port flowed continuously from the bottom of the reservoir into the big iron tank.
