The moment the promise was made, the little princess assigned Li Haoze to purchase those ancient papermaking and printing equipment, as well as related equipment for radios and transmitting terminals.

Her plan was to first familiarize herself with the operation and maintenance of these devices in the modern world, and then replicate and apply the technology in the Tang Dynasty.

Considering that Datang's industrial technology was still in its early stages, Li Haoze specially purchased old-fashioned process equipment from before the founding of the People's Republic of China.

These devices are relatively simple in structure, without complex circuit boards or modern electronic components such as vacuum tubes, which will greatly facilitate their replication and improvement within Datang's technological environment.

Thanks to Li Haoze's strong financial resources, the required equipment was quickly delivered to Mingda Laboratory.

The next morning, when the little princess came to the laboratory again, she immediately got to work.

After reading the equipment manuals provided by the merchant, she was surprised to find that the principles and operations of these devices were so intuitive and easy to understand.

"This is too easy! That's it?!!"

With surprise and curiosity, the little princess began to dismantle and reassemble the equipment.

Since she was controlling Li Haoze's body at the moment, she moved very quickly.

The little princess sat in front of the spacious workbench in Mingda Laboratory, her eyes sparkling with desire for knowledge and curiosity about the unknown.

In front of her and beside her were ancient papermaking and printing equipment purchased from the modern world, as well as radios and transmitting terminals.

She first chose to disassemble the radio, carefully unscrewing the screws and opening the casing, revealing the internal components.

While disassembling the machine, the little princess recorded the shape, material and connection method of each part.

She discovered that although these parts looked complex, they were actually designed based on some basic physical principles.

"Capacitors, inductors, resistors... these are all basic components." The little princess said to herself.

She knew how these components worked so well that she quickly understood how the radio worked.

She continued to dismantle the radio until it was completely reduced to a pile of parts.

Next, the little princess began the process of reassembly, following her previous notes and reassembling the parts step by step.

This process is much more complicated than disassembly and requires precise alignment of the positions of each part to ensure that they can be connected together correctly.

But the little princess was not impatient. She patiently adjusted the position of each part until the radio came back to life.

When the radio came out with clear sound, a satisfied smile appeared on the little princess's face.

She knew she had successfully mastered the working principles and maintenance skills of these devices.

However, the little princess did not stop there. She began to think about how to manufacture the parts of these devices in the Tang Dynasty.

She understood that the Tang Dynasty's industrial level was limited and it could not directly produce parts as sophisticated as those in the modern world.

Therefore, she needed to find a manufacturing method suitable for Datang's technological level.

She picked up a capacitor and examined its structure carefully. A capacitor is made up of two layers of metal foil and a layer of insulating material.

The little princess wondered if she could replace the metal foil with copper sheets, which were common in the Tang Dynasty, and the insulating material with paper or cloth, would she be able to make a simple capacitor?

With this idea in mind, the little princess began the experiment.

She made simple capacitors using copper sheets and paper and tested them.

Although the effect is not as ideal as modern capacitors, it already has basic capacitor functions.

The little princess was very excited, she knew this was just the beginning.

Next, she tried to use Datang's materials and technology to make components such as inductors and resistors...

Time passed slowly, and in the blink of an eye a week had passed.

During this week, the little princess stayed in the Mingda laboratory every day in modern times, studying these devices and replacement materials that could be easily obtained in the Tang Dynasty.

In the Tang Dynasty, she also took immediate action, using her status as the Princess Protector of the Nation and the power granted by Li Shimin to mobilize all the power of the court to find various raw materials and suitable talents for her.

After a week of hard work, the little princess achieved remarkable results.

In terms of talent screening, she issued recruitment orders through channels in the court, attracting a large number of aspiring craftsmen to apply.

For these applicants, the little princess first asked them to make different parts according to their different types of work.

Those who are qualified will be personally interviewed by the Development and Reform Department and sign a lifelong employment agreement.

Those who are willing to sign the agreement will become the core team of the paper mill and other factories in the future.

If you don't want to, you can only be responsible for some less important or less confidential work.

In terms of equipment research, the little princess found after many tests that the technology of the paper mill was relatively simple, and that the materials already available at Datang could fully meet production needs.

Therefore, she decisively decided to start with the paper mill and use it as a starting point to gradually advance her grand plan.

The little princess chose an ideal site near the steel plant to build a paper mill.

Not only is there abundant water resources here, but the transportation is also well-connected, which provides great convenience for the production and logistics of the paper mill.

Not only did she draw detailed design drawings herself, she also patiently explained to the craftsmen the layout and functions of each functional area.

Thanks to the hard work of the craftsmen, factories, warehouses and other infrastructure were quickly built.

During this period, the little princess personally came to the steel plant, where the fire was blazing and molten iron was flowing.

The busy figures of craftsmen and the roaring sounds of machines are intertwined to form a magnificent industrial picture.

She looked around, her heart filled with anticipation and passion.

The little princess's trip was not just for inspection, but to design and manufacture key components of papermaking equipment suitable for the technological level of the Tang Dynasty - key equipment such as presses and dryers.

Although these components may seem simple in the modern world, they required careful design and unique manufacturing techniques in the Tang Dynasty.

She first called together the craftsmen in the steel plant and showed them the drawings of her design.

The drawings clearly indicate the size, shape and material requirements of each component.

The little princess patiently explained every detail to ensure that the craftsmen fully understood her design intentions.

Then she asked the craftsmen to create a suitable rough draft, and she personally used machine tools to perform fine processing and assembly on it.

After several days of hard work, all the key components of the press and dryer were finally manufactured.

The little princess stood in front of the brand new equipment, feeling an indescribable sense of accomplishment in her heart.

These carefully designed and manufactured presses and dryers will become the core strength of the paper mill, leading Datang's papermaking technology to new glory.
