Shi Heng carefully held out a long-necked porcelain bottle.

Porcelain vases are common Dingzhou porcelain on the market, and are not very good. Although they are white porcelain, they can be turbid yellow and the porcelain color is not pure. However, they have glaze, and there is a pointed mouth and a bottle stopper on the mouth. The vase does not look like a vase, and the teapot does not look like a teapot, and it looks very strange.

However, Shi Heng held it in his hand, as if he was holding a lit gunpowder bag, with a cautious expression.

Zeng Gongliang looked at Zheng Lang suspiciously and asked, "Xingzhi, what is here?"

"Brother Le Zheng, you will know in a while," Zheng Lang said, took out a porcelain bowl, took half of the chicken with bare feathers, put it in the large porcelain bowl, and thrust at Shi Heng.

Shi Heng poured out the object in the long bottle, but Zheng Lang pushed the few people with his hands and distanced them. This thing was too dangerous.

Zeng Gongliang stared at the bowl, his eyes widened.

The bottle seemed to be water, honey, clear and slightly yellow, but it was like a ball of fire. When it hit the chicken, the chicken quickly sizzled, as if it was burned, and only a ball of coke was left after a while. Zheng Hang asked with his big eyes: "Dad, is the chicken cooked?"

"Can't touch it!" Zheng Lang shouted, swearing in his heart that Shi Heng could not let him live with him anymore, otherwise something would happen to these things.

"Xingzhi, this is..."

“It’s a good thing.”

"I understand, if it is poured onto the enemy's face..."

Cui Xian and Jiang Xing'er and Yue'er shivered together, staring at Zeng Gongliang with dissatisfaction. This Zeng Gongliang is not a good thing, not only gentle but elegant.

"It can't be watered, it's too expensive. But is it very powerful?"

"It's amazing, it's amazing," Zeng Gongliang turned around and looked at the liquid in the bowl in fear.

This is the sulfuric acid produced by Shi Heng under the guidance of Zheng Lang. It seems that in the Tang Dynasty, the alchemist Gu Gangzi recorded the "Stone Refining Gallbladder's Essence Method" in Volume 9 of his "The Nine Cauldrons of the Divine Alchemy Sutra" and obtained sulfuric acid using the dry distillation Gallbladder.

However, Zheng Lang did not use it. Instead, he used a more advanced method. Since he came back, he sent people to look for pyrite. This iron ore was not mainstream in iron ore, but some were there. It was found in the Song Dynasty, and it was once misunderstood in ancient times. Then he found raw sulphur and charcoal, bought a small yard outside the city, and put the three substances together to burn them. He covered the outside with a layer of broken pyrite, then covered it with dry soil and weeds, leaving a hole for ventilation.

In fact, the entire slow burning process is a chemical reaction process.

After more than ten days of heating, this pile of pyrite turns into iron sulfate, aluminum sulfate, flint, charcoal slag and ash, and then stir them in a basin filled with water. Iron sulfate and aluminum sulfate dissolve in water, flint, coke and ash slag precipitate. This solution is needed.

However, this solution is still not sulfuric acid. The sulfuric acid obtained from industrial production requires a series of equipment. Obviously, it was not available in the Song Dynasty, or Zheng Lang did not know the specific equipment. Therefore, he adopted the laboratory method. He also found several merchants who could calcinate sulfur glass in the capital. They were definitely not glass, and the burned out was impure. There was also a little glaze, most of which were opaque, and the substance inside would be very blurry. Zheng Lang did not want to make glass. It was not as simple as he thought. All he needed were special utensils, including crude distillation vessels.

Then the solutions are crystallized, and the crystals are heated and distilled in a sealed vessel. After the water vapor passes through the long glazed pipes, it is injected into the porcelain bottle. Is this sulfuric acid or sulfuric acid with high purity?

It is relatively simple to say, but the actual process is very complicated, and the various procedures are very complicated. Fortunately, Zheng Lang has good conditions and can mobilize a lot of resources. Shi Heng has learned to study things. He has also been working for several years and has a good understanding of this.

Sulfuric acid was finally successfully studied.

The sulfuric acid was just coming out, not what Zeng Gongliang said, but it was too terrifying to splash it on the enemy's face. It was only when it came out at the beginning. People used it to make candles and tannate leather.

This is not the case in reality, and there is also a process of understanding.

If the steam engine was the beginning of the industrial revolution and yellow gunpowder was the catalyst of the industrial revolution, the emergence of sulfuric acid was a door and window for the industrial revolution. It reacted with various metals to obtain some very pure sulfates, even purify oil, and make fertilizers. In short, there will be many uses, and there is one thing, as long as sulfuric acid is made, nitric acid is only one step away!

Shi Heng carefully took away the sulfuric acid and buried the things in the bowl together in the yard. It was so scary.

But no one understood the meaning of its appearance, and Zheng Lang did not say it, sat down and said, "This is the beginning."

"Xingzhi, what do you say?"

"In a few days, I will let you see something else."

"what?"

"A new gunpowder, its power will be dozens of times that of black gunpowder." Zheng Lang replied. It is still a laboratory product that can be studied in the laboratory at any cost, but cannot be put into actual production. Zeng Gongliang did not say anything, but just sucked the air conditioner.

He knew the power of gunpowder. What would it be if it was dozens of times more powerful than gunpowder?

"The reason I called you here today is because of this." Zheng Lang said. Zheng Lang had the intention to show the horror of sulfuric acid. In a few days, the weapons will take the opportunity to put them on the agenda.

However, there was a lack of a leader. Zheng Lang took a fancy to Zeng Gongliang and wanted him to serve as the supervisor of military ordnance while serving as an imperial edict. First, he was conservative and innovative as an official, but he was relatively honest and had some ability to govern. Moreover, he did not reject these novel things. Zheng Lang might not be relieved if he had other people.

"Why do you need to merge?"

"You will know the reason why I do both work in a few days."

The two talked about the secret camp again. Zeng Gongliang finally understood the reason. Why was the previous camp just established, and the emperor issued an edict to grant officials and promoted titles one by one. However, some Zheng Lang did not say that there were many plans. The elder Xixia and Xixia were placed in the west were not a solution, and it was too much restrained. The country would waste a lot of financial resources and troops. With the constraints of Xixia, there was no way to fight against the Khitan. The decline of the Song Dynasty would become inevitable. It was impossible for every emperor to be like Zhao Zhen, who could work diligently to maintain the country. Zheng Lang did not want his descendants to become slaves of the country to become slaves of the country later. It was not far away, but only seventy or eighty years. It was possible that his grandchildren would meet him.

The middle one is Meishan Man, and there is also the national uprisinger. In the past life, many people repeatedly beautify him regardless of right or wrong. This time, they gave him a chance to see what this person was!

The short-term one is still Xixia. Yuan Hao died, and the little emperor of Khitan came to pick up the bargain, but he didn't make any good money. He withdrew two years later. They had to expand their scale and further weaken the strength of Xixia.

The secret service camp will play some very important roles in the middle.

This is Zheng Lang's long-term plan, and there is no need to say it.

After a while, Zeng Gongliang was not rejected, and he was defeated by only a few dozen people, and half of them succeeded. Even if there were fifty people like the scouts in the early stage, he would have achieved considerable gains. He sighed: "Yes, my dynasty is too old-fashioned, otherwise he would not be so passive at the beginning of the war."

The next step is still peace.

However, Zheng Lang used the vacation time to go to the small yard in the suburbs.

The thing that comes later is even more dangerous.

This requires two things, one is glycerin. If you want glycerin, you must have animal fat and baking soda. It is very sad. Baking soda is not easy to make. There was alkaline noodles in the Song Dynasty, but alkaline noodles were not baking soda. One was sodium carbonate and the other was sodium bicarbonate. It seemed that the functions were not much different, and only one word hydrogen was missing, but the effect would be completely different.

But there is a stupid way to get some glycerin. As long as you go to the beach, find Sargasso family such as Haipengzi, Fanali, and then place it in a pot to burn. The gray powder obtained is natural baking soda. Then put animal fat in a clay pot and then use baking soda to alkalize the fat. The separated substance is glycerin. So Zheng Lang said it is a product of the laboratory, so where can I find so many Sargasso family? It must also be Sargasso family. Other algae families cannot do it. Maybe it is, but Zheng Lang doesn't know.

Due to the constraints of this previous condition, a large amount of glycerol cannot be obtained. A large amount of glycerol cannot be obtained. The following object cannot be produced in large quantities.

But don't worry, you can take it slowly.

The result of this separation can also be used to make soap. Lime can also separate fat and make soap, but it cannot be dissolved in water and has no practicality. Only when baking soda is separated can it produce real soap. Add some spices to make soap. But there is no way to get a lot of baking soda, so don’t talk about soap anymore. Zheng Lang’s intention is not here.

After getting glycerin, the master and the apprentice overcome the next difficulty and use sulfuric acid to combine saltpeter. After distillation, this crystal is another more terrifying thing, nitric acid. Zheng Lang looked at the bottle of liquid and solemnly reminded that it was too dangerous. It might cause a big explosion when it encountered a little metal powder. Even when distilling, it was far away. Its distillation gas would cause great harm to people.

Looking at these bottles of all sizes, Zheng Lang carefully reminded him and said, "Shi Heng, come out with me and have a walk."

"Here." Shi Heng locked the door with a special large iron lock. No matter whether the things inside were worth it or not, they were too terrifying. If a thief came in, he would give up his life.

The master and apprentice walked slowly along the road. The weather was very good. The weather this year was very good, mostly cloudless and clear. But this time made the farmers very sad. Not only did the court pray for rain, but the people also often organized rain prayers.

But the effect is not great, and it rains, but the rain is pitiful. I squeezed two tears and stopped immediately. Although I can see this bad situation outside the suburbs of the capital. When the riverside is near, the growth of the crops is not affected. Without irrigation water, the crops are hung weakly. Sora and beans are a little better, they are drought-resistant. The key is that there are some rice fields outside the suburbs of the capital. It is not fatal, but at least the northern harvest will be reduced by 20 to 30% this year.

Not far away is the Bian River. Although there are many disasters, it has little impact on the prosperity of the capital's commerce. Thousands of sails compete on the turbid Bian River, full of poetry and painting.

Sitting on the river bank of the Bian River, Zheng Lang said: "Shi Heng, these things are very dangerous, you must be careful."

"Here."

"Also, look for a few smart students from poor families."

"Yes. Mr. Zheng, will the things you said in the book become a reality?"

"Yes, but it will take several generations of efforts, but if you put your heart into it, some things will appear in your hands."

The news soon made Zhao Zhen learn that it was not Zhao Zhen who sent someone to follow Zheng Lang, but Zeng Gongliang said that sometimes he started talking for Zhao Zhen. When he sat down to chat, he talked about the horror of sulfuric acid when he talked about studying matters.

Zhao Zhen deliberately came to the Privy Council and asked, "Zheng Qing, I heard that you have invented a new thing?"

"It was my guidance and the students made it." Zheng Lang replied. He never admitted that Wang Anshi and the others were students, so as not to affect the future of several people because of taboos. But there is no need for Shi Heng.

"Can I give it a look?"

"Your Majesty, it's best not to flow into the palace." Zheng Lang said. The palace was originally messy and all kinds of conspiracies were unimaginable to outsiders. Even in the Zhao Zhen Dynasty, these activities were still indispensable in the harem. If a concubine became jealous and poured sulfuric acid on the other party's face... Zheng Lang shivered.

"It's okay, I'm just taking a look."

Zhao Zhen was determined to see, so Zheng Lang had to send some minor officials to Shiheng to come and perform again in front of all the officials of the Western Prefecture. Gao Ruonai asked blankly: "If this is poured on people..."

"If you don't die, you will be seriously injured. If you water too much, you will die."

"Set up a prison," Wang Yiyong said a rare sentence.

"No, the cost is too expensive. But if Your Majesty is interested, there is still something. I will take Your Majesty to the ministers of the two palaces to see."

“What is it?”

"The other kind of gunpowder is not very mature in technology. But it is very powerful."

"Take me a view," Zhao Zhi became interested. Zhao Zhen and Song Shenzong were very fun, wanted to be powerful, and were afraid of death, so they tried their best to make weapons, trying to use the advantages of weapons to reduce casualties. But weapons were only part of them, and talent was the main one. As a result, Li Xian was defeated and Song Shenzong cried sadly. This heavy blow affected his lifespan. Zheng Lang also had similar ideas, so the first thing to do was to start military, not civil. If Zhao Zhen did not propose it, he would also invite Zhao Zhen to look at the generals for advice in order to pass the next step.

"Walk."

"Your Majesty, no, let me prepare, the day after tomorrow."

"allow."

On the third day, Zheng Lang led Yulu out of the city with great might. But there were many ordinary people and officials of all sizes behind him. Zheng Lang frowned. When he arrived at the destination, Shi Heng had already stood at a foot of a mountain under a team of imperial guards.

At the foot of Tushan, a deep cave was carved, with a large porcelain groove inside. There were also some bottles and jars next to Shi Heng, all of which were stuffed into their mouths.

When he approached, Zheng Lang said, "Your Majesty, send the injunction to drive the people one mile away."

If you can't follow again, there will be danger.

"One mile?"

"Its power will not radiate to a mile, but it is limestone here, and the stone is soft. When it explodes, it will inevitably rush up a large number of stone flakes to avoid accidentally hurting the people." Zheng Lang said regretfully. In order to prove its power, he deliberately sent guards to choose this place, but he did not expect so many people to follow him.

Zhao Zhen did not believe it either. He sent the forbidden troops to disperse it, and the people were still standing in the distance. This was also caused by Zhao Zhen's style. The emperor was close to the people and had more closeness, but the people were not afraid of it.

Shi Heng started to make arrangements. Zheng Lang looked at Zhao Zhen and the big guys and said, "We will retreat too."

After the arrangement is completed, the next step is to inject the glycerin solution and nitric acid solution into the porcelain groove smoothly through the sink. This process is logically safe, but this thing is too unstable. Sometimes, something happens if you hold it in your hand and shake it. In later generations, because there are too many people who die, scientists have come up with another way to use porous substances that can absorb liquid, such as clay and sugar, to mix it with it. But it is still unstable, and something continues to happen.

Maybe this slow pouring process will explode.
To be continued...
