Among the five superintendents of the nine temples, the Shaofu supervisor is in charge of the hundred works, and will be in charge of building construction, the ordnance supervisor will be in charge of weapon production, and the capital water supervisor will be in charge of river canal water conservancy.

Although the sparrows in Jinyang are small, they are also well-equipped, bringing together craftsmen from all walks of life.

Among the young government supervisors and general supervisors, the status of carpenters is much higher than that of blacksmiths, stonemasons, potters and other craftsmen. The carpenter, responsible for the construction of the palace, without a nail, can build a palace and pavilion as high as several zhang, which is equivalent to an architectural designer in later generations, and the status is definitely not good.

Compared with blacksmiths, the carpenters of Huaguo are much more sophisticated. For the handicraft skills of the craftsmen of this era, Li Qi still admires it very much. Just ask for it, or provide simple drawings, and they'll create beautiful objects for you, some of which look like a craft. For example, waterwheels and textile machines. Looms, mills and turbines, these craftsmen have created objects that are far more delicate and durable than he imagined.

Blacksmiths use far fewer processing equipment and tools than carpenters. This has a lot to do with the salt and iron official camp that began to be implemented in the era of Emperor Wu of the Han Dynasty. Due to the severe restrictions on the manufacture and use of ironware, most Chinese craftsmen were forced to use wood to make tools and machinery, which also led to the stagnation and backwardness of domestic metalworking technology.

Craftsmen who have not read a book just lack some basic common sense, and with a little guidance, they can continue to surprise you.

There is a branch canal leading from the Jin Canal in the backyard of the Jin Palace, which provides a continuous stream of living water for the garden of the palace.

Li Qi asked the craftsmen to make some modifications to the canal, and began to trial produce and test various hydraulic machinery.

For example, the craftsmen have made many improvements to the original water-powered spinning machines and water-powered looms, and these wooden machines have become almost unrecognizable.

Most of the torsion bar transmissions have been replaced by precision gear devices, and there are even pulleys, belts that are really made of cowhide, Li Qi never imagined that the original gears made of wood could be made so precisely.

What Li Qi is looking forward to now is to replace these wooden mechanical parts with parts made of steel as soon as possible.

The carpenter master who will be the prisoner is named Luda, who claims to be the descendant of the public loss class in the Spring and Autumn Period, and naturally has nothing to do with Lu Tishi, who killed the town of Guanxi with three punches. Ruda is a gray-haired man, although he is wearing a short shirt and standing on the ground, he has his own momentum. In the face of Li Qi, the crown prince, he can also be neither humble nor arrogant, and deal with it calmly.

This is a great pride in one's own craftsmanship and pride that radiates from the heart.

Before the invention of the heat engine, the hydro turbine and the windmill were the earliest sources of power, and Hedong was not an outlet, and most of the year was windless days, so Li Qi could only write about the hydro turbine.

And that's his specialty.

Drawings drawn with a brush are not as standard as those drawn with a drawing pen on a special drawing grid, but some advanced craftsmen can understand the principle after a while. Knowledge does not have to be acquired from books, and the rich experience of craftsmen makes up for their lack of knowledge.

After living in more than 100 craftsmen and opening a carpentry workshop, blacksmith shop, and stonemason workshop, this partial courtyard near Erlong Mountain in the Jin Palace's palace has become the most lively place in the palace.

Log by log and truckloads of stone were brought into the yard, and craftsmen began to try to build three mechanical workshops powered by water turbines along the branch canal that diverted water from the mountain.

The drawings of the machinery were given to Luda's hands, and the craftsman, who claimed to be a descendant of Luban, closed his mouth in surprise after seeing the drawings, and said after carefully studying the drawings for a while: "The structure is very exquisite, this is a trick, and the royal family is strictly forbidden to pass it on!" ”

"Huh?" Li Qi felt very strange, "You know this kind of thing? ”

"The armillary sphere of Chang'an Qintianjian is powered by water power and is three stories high. My ancestors had participated in the construction of the Huntian Terrace, but that thing was a royal secret and was not allowed to be passed on, and the Lu family could only be passed on by word of mouth, not in writing. Ruda said.

Li Qi frowned: "Many good things were destroyed by this word of mouth and lost. Isn't the technique of the Mo family, how can it be spread by the public loser? ”

Luda said: "The trick is the secret of the public loser, how did it become the Mo family?" It's just that the first emperor ruled the world, and the public loser had no choice but to retreat to the mountains and forests due to the confrontation with the violent performance. ”

"This kind of thing should be popularized to the world." Li Qi replied with a smile.

The renovation project along the diversion canal in the back mountain of the Jin Dynasty is progressing very quickly, and the two sides of the ditch are full of bricks and tiles, wood, and even the large water storage pond built in the place where the spring water of Longshou Mountain gushes out is also beginning to take shape. The embankment made of mountain stone has enclosed the mouth of the stream at the spring.

The aqueduct leading to the Jin Dynasty along the embankment is a square engine room built with stone strips three feet long and one foot wide, and there is one every five zhang. The drop of more than 20 zhang allows the water of the mountain spring to flow down from the canal, providing enough kinetic energy. If the gate is opened, the gushing water will drive ten turbines to rotate in this 60-zhang long canal, driving the hydraulic spinning machines, looms and water mills used for the test to work.

A little regrettable to Li Qi, that kind of hydraulic forging hammer has not yet been successfully trial-produced.

At the same time as the Jin Wangfu aqueduct was being renovated, the mouth of the Tushui River valley of the Lutai Manor, located at the foot of Lutai Mountain, suddenly became lively.

A large area of flat land has been leveled on both sides of the Tushui River valley in Lutai Mountain, and the river has been cut off by a small water in the summer, relying on a hand-dug aqueduct to flow into the hole to cross the water. The recruited villagers used hemp rope to pull the wooden stakes on the rammed ground, and a dozen people worked in groups, and the huge sound of ramming and trumpets kept echoing in front of this valley.

Construction of a barrage dam mixed with bluestone and earth began.

Everyone knows that the construction of water conservancy is a matter that is beneficial to the present and will be beneficial for the future, but the huge cost of building embankments and dams still discourages the vast majority of officials in Huaxia. Even if it is such a tributary with a small flow of Jing, as long as it costs more than 20,000 yuan of money and grain, that is, Li Qi has the courage to dare to be such a "loser".

Li Qi didn't want to do this, but he couldn't build a barrage dam on the Fen River at present, with his current financial, material and technical resources, so he had to use his brains on the tributaries of the Fen River first.

It was also a reluctant move, as the workshops he planned would rely on the water as the main source of power.

Originally, this area of the mountain forest was a royal hunting ground, but the beasts that used to haunt from time to time suddenly disappeared, and they were frightened by such a huge human activity and ran away.

This was the beginning of his career......
