Chang'an Imperial City.

Luo Zhaoyun reviewed a stack of memorials in the imperial study room, and then picked up a drawing and outlined it on it.

Although he loved the history department and had studied history major for more than a year, he was a real engineering student when he was a bachelor's degree. Therefore, he did not leave all the knowledge in textbooks.

The figure contains parts such as water flow, levers, gears, large hammers, etc., as well as large blades, lathes, chains, etc., which are not complicatedly outlined together.

This sketch is a sketch of a hydraulic forging machine that Luo Zhaoyun thought about for many years before gradually improving.

The use of hydraulic power, in modern European exhibitions, is too close, and even a milestone.

According to the history of European industry, the earliest water hammers appeared in the 15th century. Siegrand, Germany, used a lever hammer or a drop hammer. The axle used was parallel to the hammer rod and the end was a cam, which raised the hammer rod between the fulcrum and the hammer head. The working degree of this hammer is 70 times per minute and can lift a larger hammer head. Later, a tail hammer appeared, with a forging degree of 200 times per minute and a hammer head weighing 50 to 250 kg, which greatly solved the forging process and made large-scale production possible, thus opening the prelude to industry.

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

Luo Zhaoyun felt that in this era, it was like building a tower out of thin air. It was not just a theoretical acceptance problem, but some corresponding parts, which were not even met. It was even said that if the requirements were not met, it required bearings, pistons, steel structures, etc.

In the Sui and Tang dynasties, although there were steel speculation technology, steel making technology, and steel filling technology, and steel filling technology were created and exhibited, and steel was mixed with pig iron and tin chromium elements and used for weapons and equipment, there were few steel applications for people's livelihood, life details, etc.

"First, we can make the hydraulic forging machine clear, and improve the forging process, achieve standardized production of parts, gradually replace manual smashing by manpower, and then make hydraulic spinning machines, vigorously manufacture wool, produce sweaters, improve the heating problem of clothes for the people, and also trade with foreign trade..."

Luo Zhaoyun had a lot of ideas, and the matter of pacifying the world was coming to an end. To be honest, whether it was Xiao Xian, Du Fuwei, or Fu Gongtuo, he no longer took it seriously. As long as a few heroes in the north were killed, especially the destruction of Li Tang, Luo Zhaoyun really had no worries.

At present, he began to care about the government affairs, balance the gap between the north and the south, break the monopoly of nobles, open up the road to promotion for poor families, select talents in the imperial examinations, create advanced productivity, solve people's livelihood problems, and allow the people to have clothes, food and live a life of food and clothing. This has become Luo Zhaoyun's focus.

"Your Majesty, Zhou Jin, the assistant minister of the Construction Bureau, came outside the imperial study room and was waiting for your Majesty to summon him."

"It's time to come. Take him in. I have something to say to him."

"Here!" The eunuch went out to convey the message. In an instant, Zhou Jin, the assistant minister of the Royal Construction Bureau, stepped into the hall of the imperial study room and bowed.

"Don't let your respects be flat and get up and talk."

"Thank you, Your Majesty." Zhou Jin stood up and said after standing, "Your Majesty, I entered the palace to report some things to Your Majesty."

"Oh, I can report a few things at once. It seems that the Construction and Construction Bureau has gained a lot recently!" Luo Zhaoyun smiled slightly. The Royal Construction and Construction Bureau belongs to the royal family and leaves the Ministry of Works and only obeys His Majesty's order.

The reason for establishing this department is that as a time traveler, Luo Zhaoyun has a lot of modern knowledge and theories, as well as some engineering knowledge. He plans to do some clarity and creation. If he handed over to the Ministry of Works, they are often responsible for roads, bridges, city wall construction, Great Wall repair, fortress passes and other local affairs. He really lacks manpower to serve His Majesty alone.

Second, many wonderful ideas are often difficult to accept by most people. Luo Zhaoyun does not want too many people to know that His Majesty is keen on erotic skills and ignores the great way, giving people a feeling of not doing their job properly.

Therefore, Luo Zhaoyun handed over these ideas, drawings, etc. to people who trusted, and set up a special construction bureau for research and manufacturing. After it was developed, he handed over to the Ministry of Industry to manufacture on a large scale. It will be popularized and the efficiency will be faster.

To put it bluntly, the Royal Construction Bureau is similar to the Royal Research Institute in later generations.

Zhou Jin reported truthfully: "First, it was the compass designed by Your Majesty. Five of them have been made. They were successfully formed and processed through the combination of magnets, magnetic needles and iron vessels. They were successfully formed and processed. Please take a look at it." After saying that, he picked up the newly made compass from the eunuch's tray behind him and handed it to Your Majesty.

Luo Zhaoyun took it over and saw that this compass was designed and created according to the model of later generations. It was also somewhat close and played with it in his hands. It was quite useful. In fact, in ancient history, from the weekend to the Li Tang Dynasty, the ancients called "Sinan" or "Compass" was an instrument for distinguishing directions, which was the prototype of the compass, but it was relatively rough and had errors in the direction, which was not as accurate as the real compass.

With him, whether it is the marching position or sailing out of the sea, there is a direction to avoid getting lost, which brings possibility to the arrival of the Age of Discovery.

However, the world has not been unified for the time being, the people's strength is limited, the national treasury is empty, and the navigation activities are not practical. It needs to be postponed for a few years before considering it. This thing can be temporarily used for marching and fighting, the Silk Road, going to the vassal states of the Western Regions, etc., and business travel can be used.

"What is the second thing?" Luo Zhaoyun asked.

"The movable type printing technology designed by Your Majesty has been completed in the Construction Bureau." After Zhou Jin finished speaking, he took a few single words made of burnt pottery from the tray behind him and handed them to His Majesty.

After Luo Zhaoyun took it, he looked at the single-word anti-text model. As long as he put the batches of characters in the plaque and applied black ink, he could print them in batches, providing a possibility for large-scale printing of books and newspapers. In this way, Dahua Times Weekly, etc. can be circulated in the capital as soon as possible. The court controls the media, which is equivalent to mastering the mouthpiece, which ones that want to tell the people, and which ones that need to be appropriately beautify and guide public opinion, is much more convenient.

"These two things are good things that benefit the country and the people. The court will do a great job. You will make a great contribution to the construction of the Works Bureau and will be rewarded in the future."

"Thank you, Your Majesty." Zhou Jin was a little excited. He could not have imagined that these seemingly inconspicuous things were valued so much by Your Majesty. He felt the importance of this dispatch.

“What’s the other thing?”

Zhou Jin bowed and said, "Your Majesty, the first porcelain toilet has been fired. In conjunction with the use of the water tank, you can use the water pressure to flush the filth in the toilet as His Majesty thought!"

"Oh, the porcelain toilet has also been made. This is good and can really change people's livelihood." Luo Zhaoyun smiled slightly, thinking that when the royal toilets in the future, there is no need to be filled with wooden barrels, it is also a great improvement and more hygienic and practical. I believe that in the future, the families of high-ranking officials and nobles in the capital will gradually become popular, which is another business opportunity in itself.
