Those in charge of surveying were able to work much more efficiently as soon as they got their hands on the newly designed instrument.

Tools such as compass rulers save a lot of effort when drawing maps.

Many of the new techniques proposed by Li Zhi have made the industrial park outside the city a major destination for some businessmen.

At present, most of the vacant houses in the park have been sold, and tens of thousands of people come and go to the industrial park all day.

Some of these people live here permanently, while others come here to buy goods and sell them to other regions.

Honeycomb stoves and other goods produced in the industrial park are not only used in winter.

Many people who don't cultivate their own land have used it as their main tool for boiling water and cooking.

The porcelain produced here has long been in demand.

First of all, it is because Li Su led people to research many new dyes, which can make the color of porcelain richer and more vivid.

In addition, the use of advanced technology has increased the firing temperature.

Therefore, the porcelain produced here has reached the highest level of the Tang Dynasty.

Although the price of these porcelains is relatively high, it is very popular with foreign merchants.

Nowadays, it has become the first choice for merchants from all over the world to buy porcelain.

The silk produced here is also loved for its reasonable price and high quality.

Therefore, it naturally attracts a lot of itinerant vendors.

The influx of itinerant vendors has made the market more lively and the goods sold are more abundant.

This brings great convenience to the residents living here and also attracts more people to buy property here.

Among them, the people who live in the remote places of Chang'an City are the main force to buy houses.

And the property they sold became the target of other businessmen under the leadership of Pei Mingli.

However, at this time, everyone had not realized that Pei Mingli's acquisitions had become less and less.

Even if it is an occasional move, it is to take over some connected plots.

Now Pei Mingli probably controls less than two square areas of land in his hands.

He was waiting for Li Zhi's order at the moment, ready to start the next plan.

He knew that this wait could be long.

Because the properties in the industrial park have not been sold out yet, and the demand for real estate in Chang'an City is not hot enough.

At the moment, it is only the clans and wealthy merchants who are buying properties in the city.

They buy property just to make an investment.

And there are still very few immigrants who really want to buy a house to live in.

This means that the attractiveness of Chang'an City is not very sufficient.

Li Zhi's solution is to speed up the construction of the workshop in order to increase the demand for employment.

The petrochemical plant in Yanzhou has been partially completed.

The person in charge sent here by Li Zhi was a student of Li Su.

His name is Tang Lekang, and he has a high talent for petrochemicals.

Despite his age, he was not yet eighteen years old, but he was the most secure of all Li Su's students.

At this time, he and Yan Liben were paying attention to the operation of a steam excavator.

With the loud roar of the steam engine, the excavator began to swing up and down.

Barrels of oil are pumped up from the ground and loaded into tanks to be transported to a distillation column not far away.

A pipeline was also extended next to the well.

The function of this pipeline is to divert a small amount of natural gas from the well to a nearby location for combustion.

Yan Liben asked Tang Lekang suspiciously: "Since the gas can be burned, why don't you just use it?" ”

Tang Lekang said: "The gas contained in the oil field here is very rare, and it is not worth adding another set of equipment for this. ”

Yan Liben asked again: "It shouldn't cost too much to collect it directly, right?" ”

Tang Lekang shook his head and said: "Young Eunuch Yan is thinking too simply, the gas contains a large number of toxic substances, and if you want to use it, you need to process it in multiple processes. ”

Yan Liben nodded after hearing this.

He didn't think there were so many doorways.

The two of them then inspected the other areas.

Some of these areas have been completed and some are still under construction.

It may take several years to get it all done.

There's no way around it.

Due to the constraints of the conditions, many processes can be completed directly without the right equipment.

Therefore, at present, the equipment problem can only be solved while producing first.

This is also the reason why Yan Li was originally here.

He needed a thorough understanding of all the processes involved in oil production in order to develop the equipment in a targeted manner.

During this period, many of the decomposed raw materials can only complete a part of the process, and then further processing is carried out using laboratory methods.

But for the time being, that's enough.

Because the follow-up products cannot meet the conditions for large-scale production for the time being.

The workshop to be built is also mainly manual.

For example, some synthetic fabrics require a large number of textile workers.

With the commissioning of the refinery, a new round of construction has begun in the industrial park.

These workshops will mainly produce a variety of synthetic fibers, which will then be spun into a variety of fabrics.

The production process will be provided by Li Su's students, and the design and manufacture of the machine will be led by Yang Siqi.

He is a staff member in Li Zhifu, and it is better for him to preside over these matters involving private industry.

What's more, he also includes several students now, which is just the right opportunity to exercise the students' abilities...

After more than a month of research, Li Su finally led people to develop a new paper.

Li Zhi felt very satisfied after a series of verifications.

Although the surface of this paper is not very smooth, it is very suitable for water resistance, toughness and rubbing resistance.

So Li Zhi asked Li Su to continue to study suitable inks according to the characteristics of this paper.

in order to be able to meet demanding printing requirements.

And he himself was anxiously waiting for the study personnel arranged for him by Li Shimin.

The traffic in this era is really indescribable.

Li Zhi's letter of remembrance, even if it is an expedited fast horse, wants to be delivered to Chang'an City, it will take ten days.

And it took nearly a month to send people from Chang'an to come here.

Li Zhi's construction of houses in Guangzhou is almost complete, but there are still many important links in the bank's affairs.

After more than half a month of waiting, more than a dozen household officials sent by Li Shimin finally came to Guangzhou City.

This is the number of people he decided after discussing with Wang Qi and others for a long time.

With double-entry bookkeeping and specialized accounting books, the number of people in the household department became somewhat wealthy.

Therefore, these people were sent to study in Guangzhou.

Li Zhi saw the dozen or so people in front of him, and felt that the number was really less.

So he had no choice but to make his own decisions, and recruited dozens of people from Guangzhou City.

However, with the addition of these people, they can only barely get the banks in Chang'an and Guangzhou up and running.

As for the follow-up arrangements, Li Zhi could only report the situation to his Lao Tzu and ask him to discuss it with the ministers.
