The weather was hot, and Yu Wenwen, who had been walking around the industrial area, was already sweating profusely. Because he happened to pass a cooked water (boiled water) shop, he wanted to drink a bottle of "Xiyang soda".

As the emperor, Yuwen Wen did not bring any money on his travels, but this did not mean that he did not pay for food, because his entourage came to pay.

The shopkeeper and the clerk who run the cooked water shop knew that there was a high-ranking official coming today, but when he saw the high-ranking official coming over, he was shocked. However, the mixing of "Xiyang soda" was very convenient, so although the shopkeeper's hands were a little trembling, he still quickly prepared the "Xiyang soda".

The soda from Xiyang is actually baking soda water. Put a few baking soda (sodium bicarbonate) into a bottle filled with water, then add acetic acid or lemon juice, cover and shake it for a while, the baking soda and acid react to produce carbon dioxide, and the soda becomes.

Baking soda originates from soda ash (sodium carbonate), and soda ash has natural ore. It is located at the junction of Jingzhou and Yuzhou. It has a large veins and has been mined since ancient times. Now, as an important source of soda ash, the amount of mining of the Tongbai mine is increasing year by year.

It is precisely based on the abundant soda ash source that Xiyang soda is promoted very quickly. Drink a glass of iced Xiyang soda in the hot summer and then burp a few times. It feels that the heat is taken away and it is much cooler.

This feeling is fascinating, and Xiyang soda is not expensive and easy to make, so it is very popular among the majority of ordinary people.

In the cooked water shop that operates cooked water, in addition to selling cooked water, the shop usually also sells big bowls of tea, Xiyang soda and Xiyang soda are the best drinks to sell in summer, bringing some happiness to people who are short of money.

Therefore, Xiyang soda is also called "happy water".

This name is a bit vulgar, but it is easy to remember, so it gradually became popular. Many people in Yecheng called this soda "happy water".

Yuwen Wen was drinking soda comfortably, thinking about this nickname, and remembering another "happy water" (Coca-Cola) of that era, and smiled.

Of course, baking soda is not as good as Coca-Cola, but for this era, having baking soda is enough.

Science and technology should benefit the people, so that they can have strong vitality. Over the past decade, the various technologies he has been spending money and has been transformed into practical technologies, making different contributions to changing this era.

Cooked water shops that provide cooked water survive by stubbornly building various gadgets, providing clean drinking water (boiled water) to residents in the city to reduce the risk of illness due to impure water sources.

Cooked water shops and wine shops selling cheap ale have become reliable sources of clean drinking water for urban residents. This is the efforts made by Yuwen Wen for public health.

Nowadays, most of the cooked water shops and wine shops in various places can make profits, allowing more and more people to drink clean water, but there is no need for the government to promote hygienic drinking water habits.

Cooked water shops that use high-efficiency hot water boilers to boil water can save firewood while providing residents with clean drinking water. Don’t underestimate this. The accumulated firewood shops that are spread all over major cities are not a small amount.

As he thought about it, Yuwen Wen felt a sense of accomplishment and chatted with the shopkeeper of Shushui Shop.

For the shopkeeper, he only knew that a high-ranking official came to inspect the "industrial zone" today. Now seeing the high-ranking official very young and easy to talk to, he was no longer so restrained and started talking to the other party.

Xu Shao and other officials on the side saw that the emperor was very enthusiastic about the people's sentiment, so they couldn't come forward to interrupt, so they could only wait aside.

Xu Shao took out his pocket watch and looked at it, then asked the officials around him: "Are you ready in the dyeing workshop? There is no mistake in the reception work."

"Please rest assured that the dyeing workshop has been prepared, the floor is clean and the employees are also ready to wear clothes in line with the safety production standards."

"You, go and see it again, especially to remind them that all female workers must wear hats and put their hair in the hats, remember!"

“Yes, yes!”

......

Yuwen Wen, who was inspecting the dyeing workshop, was having a discussion with the technicians. The meeting was near the dyeing tank, and everyone was holding a bottle of "happy water". As they were talking, the topic turned to Huangzhou. The atmosphere on the scene was very lively.

The printing and dyeing industry is closely related to the textile industry. Huangzhou's textile industry is developing rapidly, and the printing and dyeing industry is also developing rapidly. Now Yecheng's textile industry has entered a period of rapid development. The backbone of the printing and dyeing industry from Huangzhou is working hard to start production of new dyeing workshops.

Now they saw the emperor and the parents and officials of that year, and they felt very close in fear.

Speaking of Huangzhou today, everyone is talking endlessly, and seeing the appearance of Yecheng, a metropolis, looks more and more like Xiyang, the technicians are also very proud as a native of Huangzhou.

Back then, Huangzhou was just a dilapidated small place. Not to mention Yecheng, even Anlu could not compare.

But now, the name of Xiyang in Huangzhou has spread all over the world. Although the scale of Xiyang City is not as large as Chang'an, Luoyang and Yecheng, it is much stronger than other cities.

When it comes to hometown, people from Huangzhou and "new Huangzhou people" are proud, and Huangzhou has today's prosperity thanks to his parents and current emperor.

The topic about Huangzhou was unstoppable as soon as it started. Xu Shao, who also had an indissoluble bond with Huangzhou, forced his conversation without hesitation, and brought the topic back on track.

The emergence of sulfuric acid and hydrochloric acid has brought the chemical industry a prototype. Various new compounds are colorful, which has given Huangzhou's printing and dyeing industry practitioners a clue: Can these compounds be used as dyes?

The magical "chemistry" made the printing and dyeing industry discover a new world, so they began to seek the help of sulfuric acid and hydrochloric acid, trying to find new dyes and new dyeing processes.

Of course, now there is a helper of nitric acid.

The technicians of the printing and dyeing industry, together with the experimental personnel of Wuzhuangguan, kept doing experiments, constantly using various dyes, triacids and various compounds to see if there can be any breakthroughs.

After countless experiments, there has been no breakthrough, but the dyeing process has made significant progress.

The new dyeing process can make the cloth dyed in various dyeing workshops in Huangzhou more resistant to washing and not easily decolorized. These new dyeing processes have brought significant benefits to the dyeing workshops and have been designated as "patents". While the weaving departments adopt patents, they bring considerable income to technicians.

The patent system is a system set by Yu Wenwen to promote scientific development. All walks of life have benefited a lot from it and greatly inspired technicians to study and improve new technologies and new processes.

With the help of chemistry, the dyeing process has made significant progress, but the progress in dyes has been relatively small.

Although after countless experiments, technicians still cannot create "synthetic dyes" out of thin air.

Dyes have been derived from plants or minerals since ancient times. The so-called "synthetic dyes" are what technicians hope to directly synthesize dyes through chemical reactions without the need to extract them from plants or minerals.

In Yu Wenwen's opinion, this idea is correct, because later dyes dominated by synthetic dyes, but synthetic dyes are all organic dyes, which involve organic chemistry.

With the current low chemical level, the idea of ​​synthetic dyes is simply impossible to achieve in the short term.

Yu Wenwen's chemistry knowledge is limited to high school, and he has almost forgotten it except for some common sense. It is impossible for him to point out the right direction for technicians to engage in organic chemistry research.

But it is true that the dyeing process has made progress anyway. With the official production of sulfuric acid and hydrochloric acid workshops, the new dyeing workshop will also be put into production in Yecheng to dye the fabric woven from the weaving company with colorful colors.

Cloths that are affordable and relatively washable but not easy to decolorize can destroy the traditional hand-crafted textile industry and cause fundamental changes in the social and economic structure.

Therefore, Yuwen Wen also had high hopes for the printing and dyeing industry. He walked around the dyeing workshop for a few times and talked with the technicians for a long time before returning to the palace at Xu Shao's strong request.

Because the curfew time is coming.

Although the emperor can be an exception, Yuwen Wen generally does not do this. As the rulemaker, he has always taken the lead in abideing the rules and curfews, and in general, of course, is no exception.

After drinking the last bottle of "happy water", Yuwen Wen walked out of the dyeing workshop.

The carriage was ready, and the guards surrounded them to block the direction where all the assassins might attack.

Yuwen Wen got on the carriage and asked Xu Shao to accompany him. He did not intend to highlight Xu Shao's differences, but he had to hurry up and explain to the other party about some things.

"I'm going to Hebei... cough cough..." Yuwen Wen said and coughed a few times. This sentence made him feel as if he had turned into a mustache, so he quickly changed his words: "I've been here at the eastern tour, and I don't know if I'll come again next time..."
