In early spring and February, the earth thawed, everything recovered, and the whole Guanzhong began to have spring, but the cold temperature has not completely faded.

However, the ice in the Wei River has melted, and the dead grass on the riverbank is already protruding from the buds.

The government and yamen in various localities are organizing people to measure the land, redistribute the land according to the population, and implement the practice of guaranteeing production to households.

There is still a month to go, and spring ploughing is coming, so we have to be busy.

Luo Zhaoyun paid attention to the improvement of people's livelihood, paid special attention to the land issue of the people, and no longer gave thousands of acres of land to officials at every turn, making land highly concentrated, which is where social contradictions are sharpened.

He implemented a new policy of dividing land according to population, changing every five years, and re-dividing land per capita according to the new population and the married population, so as to ensure that the cultivators have their own land.

The people of Dahua feel at ease, because the land is an unexpected source of survival for them.

On this day, Luo Zhaoyun sent people to invite several master craftsmen, including Yuwen Rutong, the son of Yuwen Kai, who also came, and the others were skilled craftsmen, but they did not have a title, so when they entered the palace and saw His Majesty, they were all a little shocked.

"Masters, don't be restrained, I have summoned you to discuss some matters and arrange a few tasks for you."

One of the old craftsmen is named Lu Duanmu, a descendant of Lu Ban, his age is close to Huajia, and he has the highest status in this group of craftsmen, he arched his hand and said: "Don't dare to be, we are just commoners, Your Majesty is so polite and virtuous, personally summon us who can only 'obscene craftsmanship', so that all the craftsmen are surging, no matter what task His Majesty assigns, Lao Yu and several craftsmen and masters, will definitely do it!" ”

Luo Zhaoyun smiled and nodded, moved by the spirit of the old craftsman's dedication to scientific research, and affirmed: "Your gentlemen's research spirit in engineering and technology, I am very pleased, the imperial court has always focused on the system and military discipline, agriculture and the three major aspects, and I Dahua newly established the country, change the law to become strong, but we must start from all aspects, so as to moisturize things silently, and imperceptibly change the lives of the people of Dahua, engineering and machinery technology, in the eyes of Confucianism, is regarded as skillful skills, not elegant, but in my opinion, it is a major factor in the rejuvenation of the country, therefore, We will knight all the old gentlemen, set up a research institute, specialize in scientific research, emphasize experiments, invent and create, and improve the progress of Dahua iron smelting, shipbuilding, mechanical engineering, etc. ”

When a few people heard this, they were all surprised, can they, the craftsmen, also be added to the ranks?

It seems that in the Sui Dynasty, there was only Yu Wenkai, who was responsible for many large projects and projects when he was a young government supervisor, and was respected, and the rest of the craftsmen and masters were just grass people, and the monk class looked down on them.

Next, Luo Zhaoyun took out a sketch, on which some parts and mechanical sketches were drawn, and handed it to these craftsmen.

"In order to process these iron parts, there needs to be great progress in ironmaking, otherwise the quality of the workpieces will not meet the requirements." Lu Duanmu sighed.

Luo Zhaoyun said: "At present, there are still ordinary bellows and firewood in iron smelting, and there is a lack of fuel with a higher ignition point? ”

"Fuel?" Several craftsmen were a little unfamiliar with the new words.

"What's the heating to burn?" Luo Zhaoyun further explained.

"Your Majesty, I've been using charcoal for now." Yuwen Rutong replied.

Luo Zhaoyun nodded slightly, charcoal, that is, the impure amorphous carbon that maintains the original structure of the wood and the residual tar in the holes, charcoal is used in the smelting of bronzes in the Shang Dynasty and the Spring and Autumn Period and the Warring States Period, and has been used in the Wei, Jin, Southern and Northern Dynasties periods, although coal resources are abundant and more useful, but if it is used for iron smelting, the coal will release a large amount of sulfur elements, resulting in many impurities in pig iron, which is easy to brittle and break.

"I have an idea, if a large amount of charcoal is used, the cost is too high, you need to cut down countless wood, causing serious soil erosion, damaging the environment, there is a carbon resource in the ground, called coal, the reserves are amazing, but it is not suitable for iron making, this coal, high temperature to make coke, is the best fuel for iron smelting and steelmaking."

"Coal, coke? Is it also a type of charcoal? These master craftsmen were stunned.

Luo Zhaoyun smiled and said: "Don't worry, these things, I will send a special exploration team to mine coal and come back, make coke for trial, you at this stage, or try charcoal, by changing the capacity of the furnace, increase the air content, and try the blower device, increase the furnace temperature, and make a batch of high-quality iron, which is used in the manufacture of hydraulic machinery, as long as a few can be made and put into production, more high-quality iron will be created, so that repeated cycles will get better and better." ”

These craftsmen listened to the words of Emperor Dahua, and for them, it was a great encouragement, and if the king of a country attaches so much importance to craftsmanship, he will definitely be able to make great progress.

Luo Zhaoyun continued: "There are several equipment models on the sketch, in addition to the hydraulic forging machine, the others are cutting machines, textile machines, etc., the principle is similar, that is, it is best to operate differently, I don't know much about textile structure, you can think about it yourself, I suggest, you can divide the group, some are responsible for iron smelting, some are responsible for castings, some are responsible for operating mechanisms, and some are responsible for hydraulic structures. ”

"I'll get it." When the craftsmen heard this, they drew inferences from one another, and in the exchange with His Majesty, they drew many conclusions and new ideas.

"Okay, let's go back and prepare, brainstorm, these researches, the sooner they are invented, the better, and the imperial court will transfer some students from the engineering college to do apprenticeship and internship research with you!"

"Yes, Your Majesty!" The craftsmen and craftsmen were ready to withdraw from the hall, their faces were radiant, and they suddenly felt the importance of their profession, which had never been done before, Shi Nong Industry and Commerce, deep-rooted thinking, their craftsmen and merchants were about the same class composition, and they did not have business travel and money, so the situation was even worse, and now Dahua attaches great importance to it, and they feel very proud.

Luo Zhaoyun sighed lightly, the Chinese are one of the smartest races in the world, but because the royal family and nobles of the dynasty, for their own selfish interests, consolidate their own political power, and pass on the stability of the family and the world, every dynasty disdains natural science, and even suppresses it, but vigorously advocates Confucianism to the extreme and extreme.
