Chang'an Imperial City.

Luo Zhaoyun was in the imperial study, and after reviewing a stack of folds, he picked up a drawing and sketched it on it.

Although he loves history and has studied history for more than a year, he was a real engineering student when he was an undergraduate, so he did not throw away some textbook knowledge.

There are parts such as water flows, levers, gears, and large hammers, as well as large blades, lathes, chains, etc., which are not complicatedly delineated.

This sketch is a sketch of a hydraulic forging machine that Luo Zhaoyun has been thinking about for many years and gradually perfected.

The use of hydraulic power, in the modern development of Europe, the manufacture of hydraulic lathes, etc., is too close, even a milestone.

According to the industrial history of Europe, the earliest water hammer appeared in the 15th century, the first in Siegrande, Germany to use a lever hammer or drop hammer, the water wheel shaft is parallel to the hammer bar, the end is a cam, so that the hammer rod is raised between the fulcrum and the hammer head, the working speed of this hammer is 70 times per minute, and can lift a larger hammer head; Later, the tail hammer appeared, the forging speed was 200 times per minute, and the hammer head weight was 50 to 250 kg, which greatly solved the forging process and made mass production possible, thus opening the prelude to the industry.

At the end of the fifteenth century, hydraulic stamping machines and hydraulic casting machines appeared one after another, providing material conditions and possibilities for the invention and creation of steam engines later.

Luo Zhaoyun feels that in this era, to invent the steam engine is like building a pavilion out of thin air, not just a matter of theoretical acceptance, but some corresponding parts, which are not at all. It is even said that if it does not meet the requirements, bearings, pistons, steel structures, etc. are required.

In this Sui and Tang dynasties, despite the creation and development of steel frying technology, 100 steel making technology, and steel filling technology, steel has had some development, mixed with pig iron, tin and chromium elements, and used for weapons and equipment, but for people's livelihood, life details, etc., steel applications are still very few.

"The first invention of the hydraulic forging machine can improve the forging process, standardize the production of parts, and gradually replace the manual smashing of manpower, and then manufacture water-powered spinning machines, etc., vigorously manufacture wool, produce sweaters, improve the clothing and heating problems of the people, and ...... foreign trade."

Luo Zhaoyun has a lot of ideas, and the matter of pacifying the world has come to an end, frankly speaking, whether it is Xiao Miao, or Du Fuwei, and Fu Gongtuo, he no longer cares about it, as long as a few heroes in the north are ambushed, especially the fall of Li Tang, Luo Zhaoyun really has no worries.

At present, he began to care about the government and politics, balance the gap between the north and the south, break the monopoly of the nobles, open the way for promotion for the poor, select talents for the imperial examination, create advanced productive forces, solve the problems of people's livelihood, so that the people have clothes to wear, food to eat, and live a life of food and clothing, which has become the focus of Luo Zhaoyun.

"Your Majesty, Zhou Jin, the squire of the Construction Bureau, has arrived outside the imperial study, waiting for His Majesty to summon him."

"Come at the right time, bring him in, I have something to say to him."

"Whoa!" The eunuch went out to convey, and in an instant, Zhou Jin, the squire of the Royal Architectural Bureau, walked into the hall of the imperial study and bowed.

"Excuse yourself and get up and speak."

"Thank you, Your Majesty." Zhou Jin got up, stood up and said, "Your Majesty, the minister entered the palace to report a few things to His Majesty. ”

"Oh, I can report a few things at once, it seems that the Construction Bureau has gained a lot recently!" Luo Zhaoyun smiled slightly, this Royal Construction Bureau directly belongs to the royal family, separated from the Ministry of Works, and only listens to His Majesty's dispatch.

The reason why this department was established is because Luo Zhaoyun, as a traverser, has a lot of modern knowledge and theory, as well as some engineering knowledge, and he plans to engage in some inventions and creations, if it is handed over to the Ministry of Industry, they are often responsible for roads, bridges, city wall construction, Great Wall repair, fortress Xiongguan and other local affairs, there is really a lack of manpower to serve His Majesty alone.

The second is that many whimsical ideas are often difficult to be accepted by most people, Luo Zhaoyun doesn't want too many people to know that His Majesty is keen on lewd craftsmanship and skill, ignoring the avenue, giving people a feeling of not doing their job.

Therefore, Luo Zhaoyun handed over these ideas, drawings, etc., to trusted people, set up a special manufacturing bureau to study and manufacture, and after the development was developed, it was handed over to the Ministry of Industry for large-scale manufacturing and popularization, and the efficiency would be faster.

To put it bluntly, this Royal Architectural Bureau is similar to the Royal Academy of Science in later generations.

Zhou Jin truthfully reported: "First of all, it is the compass designed by His Majesty, and five of them have been manufactured, and through the combination of magnets, magnetic needles, and iron utensils, they have been successfully shaped and processed, please take a look at them." After the words fell, he picked up the compass he had just made from the tray of the eunuch behind him and handed it to His Majesty.

Luo Zhaoyun took it and looked at it, this compass was designed and created according to the model of later generations, and it was also a little close, and it was quite easy to play with in his hand. In fact, in ancient history, from the weekend to Li Tang, the ancients called "Sinan" or "guide" as a kind of instrument to identify the direction, which is the prototype of the compass, but it is relatively rough, and there are errors in the identification of the direction, which is not as accurate as the real compass.

With him, whether it is the side of the march or the voyage to the sea, there is a direction to avoid getting lost, which brings the possibility of the advent of the Age of Discovery.

However, for the time being, the world is not unified, the people's power is limited, the treasury is empty, and the navigation activities are not practical, so it needs to be postponed for a few years.

"What's the second thing?" Luo Zhaoyun asked.

"The movable type printing designed by His Majesty has been manufactured by the Bureau of Manufacturing." After Zhou Jin finished speaking, he took a few words made of pottery from the tray in the hands of the eunuch behind him and handed them to His Majesty.

After Luo Zhaoyun took it, he looked at the Yangwen anti-text mold of the single word, as long as the batch of word molds was placed in the word plate and smeared with black ink, it could be printed in batches, providing the possibility for large-scale book printing and newspaper printing, so that Dahua Times Weekly and so on could be circulated in the capital as soon as possible, and the imperial court controlled the media, which was equivalent to mastering the mouthpiece, which wanted to tell the people, and which needed to be properly beautified and guide public opinion, it would be much more convenient.

"These two things are good things for the benefit of the country and the people, the court will make a big difference, your construction bureau, you are indispensable, and you will be rewarded in the future."

"Thank you, Your Majesty." Zhou Jin was a little excited, he couldn't imagine that these seemingly inconspicuous things were so valued by His Majesty, and he felt the importance of this dispatch even more.

"What's the other thing?"

Zhou Jin arched his hand and said: "Back to Your Majesty, the first porcelain toilet has been fired, and with the use of the water tank, it can already be done as Your Majesty thinks, using water pressure to flush the filth in the toilet!" ”

"Oh, the porcelain toilet has also been manufactured, this is good, and it can really change people's livelihood." Luo Zhaoyun smiled slightly, thinking that in the future, the royal toilet, with a porcelain flushing toilet, does not need to be held in a wooden barrel, it can be regarded as a great progress, more hygienic and practical, presumably it will not be long before the homes of high-ranking officials and nobles in the capital will gradually become popular, which is another business opportunity in itself.
