Just as he was thinking, Li Tai sent the ministers out of the hall, turned around and returned, saluting and greetings.

When His Majesty Li Er saw the fat son, he felt better again. He asked Li Tai to sit down and asked with concern: "Can Qingque eat?"

He was so fat, and even asked him if he had eaten. It was obvious that the fat guys in the world became fat because their parents were too concerned and pampered.

Li Tai hurriedly replied: "My son asked Xu Kucheng's mansion to discuss matters and arranged a meal to entertain him. As soon as Xu Kucheng was sent away, he heard that his father was angry. He was afraid that his father would be very angry and hurt his body, so he hurried over."

His Majesty Li Er was very pleased. This fat son was so filial. He was worried that he would be angry. He rushed over with the sun and sweating profusely.

"What did you ask Qi Lin to discuss?" His Majesty Li Er called the palace servants to wipe Li Tai's sweat and water, and asked casually.

Li Tai told the truth that he encountered difficulties in printing movable type, and it depends on whether Xu Qilin could do it.

His Majesty Li Er said with a slight head, "If you talk about wonderful ideas, Qi Lin is indeed a good match. Well, this ink sounds feasible."

Li Tai said: "Xu Kucheng found the crux of the problem just after a little thought. It is really admirable to think of a solution."

"I haven't succeeded yet, so there's no need to rush to praise him." His Majesty Li Er showed a teasing smile on his face and said, "This kid, didn't take the opportunity to ask you for any reward, right?"

Li Tai laughed and said, "I didn't ask for compensation. He just proposed to buy a set of lead type molds, and Erchen has agreed."

"He wants to print a book?" His Majesty Li Er shook his head and said, "A set of lead type molds is very valuable. This kid will not spend his own money, so he must ask me for it."

Li Tai pondered for a moment and said, "I'll give him a set. As long as it is used in public places, it's okay."

His Majesty Li Er looked at Li Tai with a little strangeness, wondering how he took out the money.

Li Tai hurriedly explained: "Because my son has been repairing the mansion, some officials have already advised my father. My son wanted to save this money and do something more useful."

"It's so good." His Majesty Li Er nodded with relief and said, "Wang Cang, Wang Cang of Dongping of Han, said 'the most joyful thing', and I hope my son will be willing to do it."

"My son is obeying the teachings of his father and dare not forget them." Li Tai bowed respectfully.

His Majesty Li Er smiled and was very satisfied with the fat son's performance today, but he was reluctant to let him go, so he chatted casually.

………………………….

There were only a few sheds in the workshop outside the city, and the work of building foundations and building houses was busy, but a large area had been fenced, which did not prevent Xu Qilin from starting the experiment on wool textiles.

Several sinks are lined up in a row. After weighing the cut wool length, the wool washing process is carried out in these sinks.

Since it is the experimental stage, all data must be recorded in detail and carefully. The concentration of hot water is used, and the temperature is about the hot water. Without accurate measurement instruments, you can only record the amount of materials used and the proportion of warm water.

After Xu Qilin explained to his officials, he did not focus on this simple process, but explained the drawings he had drawn to several craftsmen so that they could build a foot-pin combing machine.

"It's like a nail board, but the nails are not very long." A craftsman looked at the steel nail comb on the drawings and asked Xu Qilin in confusion.

Xu Qilin nodded and said, "What you said is a shrinking nail board that removes the grassy debris in the wool and tries it straight."

In fact, the entire production process of wool spinning is not complicated. Tang Dynasty, which has strong experience in silk textiles, was not difficult to spin and weave. Some ready-made machinery can be slightly modified, which means washing and combing is more technical.

The successful manufacturing of the combing machine also saves the energy and time of working on a carding machine in the future, which can be said to kill two birds with one stone.

After answering the questions from the craftsmen, the craftsmen went to make the same. Xu Qilin sat under the shed, savoring the tea, and when he thought about it, he invited Grandpa Song Yingxing to stand proudly in the Tang Dynasty with a book called "The Art of Heaven and the Art of Creation", and was well-known and had no choice but to go all the way.

After all, "The Art of Heaven" represents the highest technological level in a thousand years and also includes all-encompassing production technologies such as machinery, bricks and tiles, ceramics, sulfur, candles, paper, weapons, gunpowder, textile, dyeing, salt making, coal mining, oil pressing and other production technologies. It is known as the "China's 17th century craft encyclopedia".

But this is not what you have to do now, and you can only do it the same thing to do. Xu Qilin also pointed to this promotion and made a fortune!

As for the newly obtained task ink, it is not difficult for Xu Qilin. It is almost impossible to change the bonding material from water to oil, which is simpler and easier than making ink ingots.

Of course, Xu Qilin seems to be able to choose tung oil as the binding material at present. Such a single choice made him still not very satisfied.

Soybean oil may be fine, and there are other vegetable oils. Xu Qilin thought about this and found that in the Tang Dynasty, there were very few types of vegetable oils, and quash was considered an oil plant with relatively large yields.

If coal tar can be used, that should be the most economical, right? Xu Qilin closed his eyes slightly and began to think about where to dig coal in the chair.

Just as I was thinking, I heard people shouting at the horses neighing in the official road in the distance, and a large group of people were furious in their clothes, as if they were traveling back to the city.

Xu Qilin didn't care, no matter who he was, it didn't matter to him.

In fact, Xu Qilin had long thought of coal, and how warm the kang was in winter. He also asked someone to inquire about it. Although there are carbonites for sale on the market, the amount is very small, and most people are not used to using it.

When it comes to where there is coal, Xu Qilin certainly knows the approximate location and the large open-pit coal mines. However, according to ancient transportation capabilities, without trains or cars, the distance is too far lost.

According to Xu Qilin's estimate, a coal mine can cover up to a radius of three to five hundred miles. If it is farther, it will be a loss to you.

Following this idea, Xu Qilin began to screen the areas around Chang'an one by one. Soon, he fell in love with Tongchuan and Weinan, which are both good places rich in coal resources.

Tongchuan is less than 200 miles north of Chang'an, and about 150 or 60 miles from Weinan to Chang'an. There is also the Wei River that can be transported through water, which should be more convenient.

Well, it's time to go to the Ministry of Industry to invite several exploration experts to Weinan to find "black gold"! Xu Qilin waved his hand to drive away a few little flying insects and made a decision in his mind.

The noise was closer. The group of people on the official road did not rush to travel, but stopped and pointed at it. Then, several knights came on horseback.

Xu Qilin didn't know what was going on, so he stood up and looked around.
