Sulphuric acid is made in much the same way, using pyrite, an ore with a golden glow on the surface, which was previously mistaken for gold, hence the nickname "Fool's Gold".

The pyrite is placed in a boiling furnace shaped like a funnel for roasting to produce sulfur dioxide gas, which can be dissolved in water to form sulfurous acid, and sulfurous acid can be obtained by oxidizing sulfurous acid again. The remaining slag is an excellent material for smelting pig iron.

The difficulty lies mainly in the production of the boiling furnace, which is composed of steel shell lined with insulation bricks and lined with refractory bricks. The upper layer has a much larger cross-section than the lower level, so it resembles a funnel, with air intakes at the bottom of the funnel, and refractory brick concrete hearths on top of it, with side openings for pyrite entry and discharge of slag.

The top side of the furnace is provided with a gas outlet, which is used to receive sulfur dioxide gas, if according to the modern smelting method, the received gas will also react with the absorption tower in the contact chamber to generate pyrosulfuric acid, and then add water to obtain industrial sulfuric acid, the significance of this is that the production efficiency will be greatly increased, but Tang Sankong does not care about efficiency at present, so he does not use this cumbersome method.

The two acid factories have finally been established, the copper smelter has long been erected, and the brewery for the production of ethanol has finally gathered the raw materials for making the fixed ammunition, and the rest is to make standard copper shells, mercury thunderate primers, smokeless gunpowder, and steel warheads, and when they are assembled together, they are the unrivaled king of war!

With modern firearms, the advantage of soul masters over ordinary people will be gone, this is the first warning line for those soul masters who want to make trouble after world peace, the future world must be legal, even if you are Soul Holy Soul Douluo, you will have to accept the people's judgment if you violate the law.

This world seems to be respected by soul masters, but in fact, the people are still the masters of the house, in the past, it was the lack of an organization that could condense a plate of loose sand into a skyscraper, so that the royal family and nobles and soul masters would occupy the dove's nest, but when Tang Sanbar decided to overthrow this class, everything changed.

There is no one to stop in front of the red will!

At this moment,

The first plenary meeting of Wuhun City was being held in the meeting hall of the Pope's Palace, and everyone sat around the huge oval wooden conference table in the center of the hall, reporting the progress of their work one by one. Bibi Dong did not sit on the papal throne in the hall, but sat with everyone, Tang Sangang found a chair and sat behind Bibi Dong.

After three years of rectification, today's Wuhun Hall finally has the appearance of a medieval city hall, and the people in each position are either good at this, or people with excellent government affairs handling ability, they have talents dug up by Tang Sangang from various places, such as Dugu Yan of the Ministry of Chemical Industry, the building height of the Ministry of Metallurgy, and there are also people who originally supported Bibi Dong in the Wuhun Palace, such as Qian Jin of the Ministry of Commerce and Wang Lei of the Ministry of Foreign Affairs.

There are also some superior people found in the cultivation of managerial talents, most of them are ordinary people, not soul masters, but Bibi Dong still handed over important positions to them. And it is equipped with a soul master of the Martial Spirit Hall to protect their safety. This kind of behavior naturally makes them grateful, even if it is a royal family, there is no such case of wanton promotion of talents.

"All departments are now reporting on the progress of their work."

Bibi Dong was as cold as frost, his face was like cold snow, and his words seemed to come from the middle of winter, extremely cold.

The people present have long been accustomed to it, Qian Jin of the Ministry of Commerce took the lead in getting up, saluted Bibi Dong, and then said: "Your Majesty, the income and expenditure of the Ministry of Commerce are now at the stage of two to one to five, and about one million gold soul coins are credited to the account every month, most of which is used to distribute subsidies to many Wuhun Hall personnel, build new urban areas, open new factories, and also pay for the wages of workers, as well as school construction and teacher subsidies in several kingdoms and principalities under our control. ”

"Well, education is the foundation of a nation, and this cannot be stagnant in any way! Ask for money for money, ask for people to give to people! ”

Bibi Dong was expressionless and motioned for the next person to continue.

Next is Wang Lei of the Ministry of Foreign Affairs, with a national face, thick eyebrows and big eyes, and a righteous face, "Your Majesty, the two empires have not made any big moves recently, and the Martial Spirit Hall and the temple branches of each city are also safe, but the battle between the crown princes of the Heaven Dou Empire is becoming more and more intense, and the Snow Night Emperor is getting worse and worse for some reason, the second prince and the third prince have joined forces to assassinate the eldest prince Xue Qinghe many times, and the fourth prince Avalanche is swimming outside the mountains and rivers, and is outside the storm." ”

"And wolf thieves have appeared in many places in the Star Luo Empire, this is a bloodthirsty monster that is half human and half wolf, and the lives are ruined everywhere it passes, the Star Luo Empire sent the crown prince Dai Mubai to exterminate it, and it is still on the way, and the evil soul division appears frequently, but it can't become a climate, and it will be killed directly after we find it."

Tang Sangang frowned, why are there more and more evil soul masters, is it so difficult for civilians to live a good life?

After hearing this, Bibi Dong said coldly: "The evil soul master is addicted to killing, and he is not human, so he should be killed when he sees it!" ”

The people present nodded in agreement, the best way to deal with this kind of dehumanized guy is to hang him up and let him reincarnate.

Then came the Ministry of Education, the chief person in charge was an old man with gray hair, "Your Majesty, the education of children and young people is going very well at present, but although most adults have completed literacy, they say that it is of little help in finding a job... ”

"Leave this to me, I will send a group of people from Notting City to teach adults to learn technical knowledge in cooking, mechanical processing, etc., and open two new colleges, New Oriental College and Lanxiang College, only adults are recruited, and after graduation, the factory in Wuhun City will be preferred, and there should be an endless stream of participants."

Tang Sangang directly took this matter on himself.

"Thank you, Lord Tang."

The old man smiled, although there are only two academies, which cannot solve the problem of a large number of civilian employment, but at least it is a start.

However, Tang Sangang was still full of expectations for these two academies, after all, this was a famous name in the previous life, and it sent a lot of skilled talents to the society, so why can't Wuhun City copy it.

Next is the Ministry of Supervision, the first bad news finally appeared, there were ink greed among the staff of the Wuhun Palace, fortunately, there were fewer people, and now they have been escorted back.

"Let's go to the mines, and give him back his freedom in twenty years, as a warning to everyone."

Bibi Dong pronounced the fate of this person without emotion, Tang Sangang nodded in his heart, although he knew that this matter could not be avoided, but since someone made a bird, he naturally wanted to kill the chicken and make an example.

The Ministry of Agriculture didn't have much to do, everything was normal.

The chief of the Ministry of Industry was Tang Hao, who did not come at all, and Siyu, the apprentice of Lou Gao, served as the second speaker.

"Ahem, at present, the output of the mechanical processing plant is saturated, and the order has been scheduled for three years, so I propose to expand three more mechanical processing plants, whether it is a steam train, or a steam car, as well as the steam tractor handed over to us by Master Tang Hao, or even a bicycle factory, which requires a lot of manpower and machine tools to produce."

"The current production is already a bit stretched, and if you want several projects to be carried out at the same time, expansion is a must, and I'm done."

Bibi Dong nodded indifferently and said that he completely agreed, and then naturally the Ministry of Finance would allocate funds and the Ministry of Construction would take over the expansion.

The Ministry of Railways is also headed by Lou Gao's apprentice, Si Long.

"The steam train is working fine at the moment, but I don't know when it will be able to lay the tracks somewhere else?" Silong was puzzled, obviously able to operate, but he claimed that there were various problems, and the work of laying railroad tracks was also delayed again and again, and now there is only a circle of railroad tracks around the industrial zone.

"The time has not yet come, and laying railroad tracks outward now will only attract the suspicion of the two empires, and the gains outweigh the losses."

Tang Sangang shook his head, the two empires are not stupid, they will let them spread the rails all over the world, and it involves the exchange of interests, Tang Sangang is 10,000 unwilling to hand over the site to the local lord to be responsible, this kind of thing is better to be fully responsible.

Tang Sanbar of the Ministry of Metallurgy has already mentioned that Lou Gao is in charge, and the short and fat Lou Gao looks impatient,

"The steel production in the industrial zone is still insufficient, cars, bicycles, steam engines, trains need ingots for each project, and I propose to triple the number of blast furnaces! I also have to build a few more converters, and in addition, this kind of meeting will not call me in the future, and I have made several car parts when I have time to sit here. ”

Bibi Dong directly ignored Lou Gao's complaints and agreed to the incremental request of the blast furnace and converter.

Finally, the Ministry of Construction, the chief person in charge is an ordinary person, and his appearance is also the kind of appearance that stands out from the crowd, and he is nervous and frightened in the face of many bigwigs on the scene.

"There is no problem with the new factory and two colleges in the industrial zone, and the construction of the six urban districts is still in progress, the fastest construction speed of Haotian District has been basically completed, and the temporary housing built outside the city is also very safe, and there have been no major accidents for more than a year."

Bibi Dong had a straight face, still indifferent.

"Well done, keep it up."

The chief of the Ministry of Construction nodded hurriedly, then hesitated, but gritted his teeth and said:

"There is one more thing, according to the current urban planning, the future Wuhun City will definitely be a big city with a number of people far exceeding the number of Tiandou Xingluo, there is no river in the city, and it will not be very convenient for residents to use water in the future, according to the current situation, the number of wells is estimated to be too small, and at least twenty wells need to be planned. . . ."

"It doesn't have to be this way! The well is not enough for the canal to make up! We can dig a canal directly and divert water from the nearest big river. ”

Tang Sangang was full of smiles, Xingluo City made Wuhun City naturally also, and digging a canal over, it would be more convenient to connect water to every household in the future, as for electricity, now there is no clue, the passage has been planned, heating is not needed, Wuhun City's winter is not cold.

The others were surprised, and the chief of the Ministry of Construction was even more stunned, did the canal be dug when it was said to be dug? The nearest river is also hundreds of miles away, and it takes time, effort and money to build.

And Tang Sangang is full of confidence, just digging the canal, saying that the Hammer of Dawn has not appeared for a long time.
