In late March, it is late spring, and the tall locust trees on both sides of the street fall from time to time. There is a hint of fragrance wafting in the wind, adding a little warmth out of thin air. The sky is high and blue after the rain. Occasionally, a few bald fly by in pairs with sweet singing voices. In the far distance, the white clouds lie lazily and quietly, like locust flowers on the ground, slightly undulating.

During this period, the Tiantang Daily and Weekly newspapers hyped up the bank's business scope and the news of the imminent issuance of a new currency. Begin to pave the way for the opening of the bank in the future.

Amid people's discussions and speculations, Tiantang Bank has finally officially opened, and the bank is located on the edge of the imperial city. The new currency was officially issued simultaneously in various places, and the exchange business began. In order to prevent large-scale money laundering, the bank has specially instructed personnel dispatched by the Ministry of Officials, the Ministry of Households, and the Ministry of Criminal Affairs to verify the identities of the exchange personnel, exchange their real names, and conduct the identification of Tongbao and silk silk.

All kinds of shops have been ordered to settle in Singapore dollars, and this year's taxes and rents and officials will also be settled in new currency. The deposit and loan business was also carried out, and the management model was basically similar to that of later banks. For a time, there was a steady stream of people exchanging money, and the new currency and banking business became the main talking ...... for the people of the world.

Road construction in the capital is also in full swing. Due to the mobilization of several thousand people, the construction of the division and section at the same time, it is expected to be completed in July. In addition, the road from Beijing to Luoyang, Jinyang and Yizhou has also begun to plan, due to the newly expanded cement plant, just set up and put into operation, the cement output is insufficient, can only be used to build the roadbed with Sanhe soil, after the cement is enough, and then the concrete pavement is laid.

Li Chengqian stood on the side of the road and looked at the construction site with a smile on his face. Then he looked at Wang Xuance, who was full of pride and excitement, and kept explaining the situation. I couldn't help but muttered to myself, is it a little too much to underestimate his talent when he is used here, although he is used to seeing the construction scenes of later generations, but Wang Xuance can manage these people who don't understand anything so decently, it is really beyond his expectations.

In order to arouse the enthusiasm of the slaves to work, Li Chengqian made a promise to these slaves who worked, as long as they performed well, or had special talents, or had outstanding contributions, and worked for five years, they could redeem themselves, turn into good families, and become real residents of the Tang Dynasty. But there are not many people who can work and have the ability after all, and this kind of construction in dozens of areas at the same time is a big scene of thousands of people. Without a good organizer to direct the dispatch, the efficiency and quality simply do not meet the requirements.

Li Wujie walked over, looked at his face, smiled and whispered, "Da Lang, do you want to go to the workshop to have a look." ”

Listening to Li Wujie calling himself a big man, Li Chengqian was a little excited in his heart, looking at Li Wujie's smiling eyes, he suddenly felt weak, nodded awkwardly, turned to Wang Xuance and said: "Qiming, let's take a car together, let's go to various production workshops." ”

"There are many questions at the production workshop site that need to be consulted by His Highness." Wang Xuance responded excitedly. After that, the three of them left the road repair site in a carriage and went straight to the production workshop.

In all production workshops, Li Chengqian implemented the method of appointing capable people to higher positions, and also reused those who were born as slaves, and encouraged innovation by restoring good names as rewards. For those who do not have special skills, they will be arranged to study and read for free, and they will only be used in quantity. For a time, no matter whether good or bad, everyone was full of hope for their future.

The most interesting part is the newly built coking workshop, which is designed according to the production process of the coking plant he has seen in later generations. All but a few stewards and craftsmen were slaves. In accordance with Li Chengqian's ideas and methods, these slaves have now come up with the best ratio after more than a dozen coal blending trials and continuous improvement of facilities, equipment, and technology. According to the coal from different origins, according to different proportions, qualified coke can be refined.

Although the coke market workshop is small, the facilities are very simple, and most of them are manual, and the output and efficiency are very low, but it is already possible to start continuous production. If there is enough coking coal, the monthly output is initially estimated to reach 1,000 tons. In the future, with the increase of coal production, it is estimated that there will be no problem in expanding the scale of coke production capacity.

Although Li Chengqian understands the principle and technology, the recovery rate is very low due to the lack of facilities and equipment, technology and personnel skills, and only ammonia and coal tar can be recovered. As for the by-product gas, which cannot be preserved and has a high calorific value, all of it is reused and used as fuel to make iron utensils, and the use of gas has begun to test the firing of calcium carbide. However, it has not been successful so far, after Li Chengqian explained the principle and analyzed it on the spot with everyone, it was finally determined that the crucible quality and the temperature of the reactor did not meet the requirements. I can't think about it for a while, so I can only offer a reward and let everyone find a way to innovate to solve it.

However, in Li Chengqian's mind, this achievement in front of him is also a thing worth being happy about. After all, the first steps have already been taken. As long as there is ammonia, then the production of soda ash and fertilizer can be carried out, and ammonium nitrate explosives can also be made continuously.

As long as ammonium nitrate explosives are available, the scale of coal mining and metal and non-metal minerals can be expanded. With soda ash, the cost of daily necessities can be greatly reduced, and with other raw materials, the processing and production of chemical products can also be further developed. If calcium carbide can also be produced, combined with the refining of coal tar and wood dry distillation, whether it is home lighting, mining lighting, or organic chemical industry, it can begin to develop. Although the road is long, there is hope.

The rest of the workshops, the most anticipated is the steelmaking workshop, which is next to the coking workshop. Today, the steelmaking and mechanical engineering workshops have been merged into one place, and the area of the plant has increased several times.

After a period of experimentation, crucible steelmaking technology has been able to produce stably. According to Li Chengqian's analysis, the strength of medium carbon steel should be completely fine. As for alloy steels and the like, although he has explained the principle and general smelting composition to everyone, such as nickel-chromium-tungsten ore and the like, he is not a professional technician in the identification, separation, refining, temperature and process of minerals. Although the direction and path are pointed out, it is estimated that it will take a long time for everyone to explore and experiment.

A new steelmaking blast furnace has also been built on the initiative of the craftsmen, but it still needs to be completed. When coke, ore and other raw materials, blast equipment, and casting equipment are all in place, the furnace can be opened to test the most primitive cottage converter steelmaking.
