    The next day, after Chen Wanrong got up, he used breakfast and rushed to the Ordnance Supervision.  Chen Wanrong thought he came early today, but he didn't expect to find out that he was the last one to come when he arrived at the weapons inspection. He couldn't help laughing at himself: "You are so early."

    Kou Yibing's white beard curled up and he smiled happily: "Mr. Chen, what day is it today? It's a day to boil salt! Can't we come earlier?"

    The burning of salt itself is not important. What is important is that the gunpowder is so powerful. They have already seen it, so naturally they want to witness it with their own eyes.  Although it was a bit unexpected, it was reasonable. Chen Wanrong couldn't help but smile: "Now that we are ready, let's get started."

    "That's what I've been waiting for!" Ye Tianheng's crutch kept moving on the ground, walking in front of him like flying.

    Chen Wanrong followed everyone to the room. He saw that all the pots and stoves were ready, and even the saltpeter was piled aside. He was waiting for him, the person in charge, to order the work to start. The preparations were really done well. Chen Wanrong wanted to  It¡¯s okay not to be satisfied.

    "Master Chen, you tell me what to do." Liu Huaide rolled up his sleeves.

    Chen Wanrong didn¡¯t say much: ¡°Light up the fire and add water.¡±

    As soon as the words were spoken, the servants raised the fire and carried the water. It only took a while to complete.  Chen Wanrong picked up the saltpeter and put it into the pot. Ye Tianheng immediately followed suit. One piece for you, one piece for me, and there will be a lot in the pot.

    Chen Wanrong clapped his hands and stood up.  Ye Tianheng was a little confused and asked: "Little friend, why is this? Isn't boiling saltwater just boiling?"

    Boiling nitrate is to separate using the principle that the solubility of potassium nitrate is different and changes greatly.  Of course, Ye Tianheng has no knowledge of chemistry, so it is normal for him not to understand.  Chen Wanrong nodded and said: "Absolutely."

    Cao Zhixiong was very surprised: "Can this also produce saltpeter? It's not the same as boiling the sea into salt, right?"

    These are two different things.  The reason why seawater is boiled into salt is because seawater contains salt. By heating and evaporating the water, salt can be obtained.  The boiling of nitrate is accomplished by utilizing the principle of rapid changes in solubility at different temperatures.  (The solubility of table salt does not change much with temperature.)

    Chen Wanrong wanted to correct his statement, but when he thought that he had no knowledge of chemistry and it was difficult to explain, he had to say: "There are just some differences."

    Cao Zhixiong wanted to ask what the difference was, but Chen Wanrong picked up a stick and stirred it in the pot, so he didn't ask and just picked up the stick and stirred it.  As the temperature rises, potassium nitrate is already dissolving. Stirring can speed up the dissolution. After a while, the saltpeter scatters and gradually turns into sand.

    This change was really unexpected, and everyone was surprised, and there was a chorus of surprise.

    Their reaction was not unexpected at all, as Chen Wanrong expected. He explained to them with a smile: "The useful ingredients in the saltpeter have been transferred to the water, so add more."

    Ye Tianheng asked for advice while adding saltpeter: "My little friend, how can I get the useful ingredients?"

    This question was exactly what everyone wanted to ask. They all agreed in unison, looking at Chen Wanrong, waiting for the answer.  Chen Wanrong said while stirring: "We'll find out later. It's not vivid enough to say it now."

    No matter how good it is, it is better to experience it in person and make people feel deeply.

    Ye Tianheng and the others stopped asking.  Seeing that the temperature was about the same, Chen Wanrong called for a stop, and everyone stopped, stopped stirring, and put the sticks aside.

    There was already some peculiar smell in the air. Chen Wanrong frowned and said, "That's how strong the fire is. Okay, everyone, please exit and we'll come in later."

    Cao Zhixiong was a little unwilling and asked: "Why do you want to withdraw?"

    Chen Wanrong explained: "Smell it, isn't it a bit strange? It's not good for your health, so just come in later."

    "Is the harm big? If not, we will just watch." Kou Yibing didn't care about the harm.

    "The harm is there, but not big." Chen Wanrong answered truthfully: "It's not big."

    "Then I'll watch." Everyone expressed their determination in unison.

    Chen Wanrong wanted to avoid it, but it was difficult to leave, so he had to follow them to guard.  After the pot was clarified, Chen Wanrong asked someone to carefully scoop the clarified liquid into a clean pot.  There was a lot of clarified liquid in several pots, and it was collected and filled into a full pot.

    "Should this sediment be thrown away?" Ye Tianheng asked as he carefully looked at the sediment in the pot.

    Chen Wanrong nodded and said: "Exactly."

    As soon as Ye Tianheng put down his crutches, he was about to start working. Kou Yibing hurriedly stopped him: "Brother Ye, please don't do it. You are old now, don't get exhausted."

    "This is the first time Ye has encountered this kind of thing in his life,"??It's true.  "

    Kou Yibing smiled and said: "This is the truth, but it is too simple. Can we not doubt it?"

    Saltpeter can be used as medicine and can cure diseases, so it is considered a common thing.  Not to mention sulfur and charcoal. It was very common. The three things mixed together turned out to be gunpowder that they could not even imagine. It was not surprising at all.

    Chen Wanrong understood their thoughts: "This is the wonder of chemical engineering. Seemingly unrelated things can undergo unexpected changes after being treated with chemical engineering. This gunpowder is just one of them."

    "The name of Chen's Chemical Industry is well known to us, but we didn't expect it to be well-deserved and so magical." Kou Yibing couldn't help but touch his beard and sighed with a smile.

    ??????????????????????????????????????????????????????????????????????????????? Sima Chengzhen, a worldly master who was extremely good at cultivating his mind and character, was so impressed by the chemical industry that he was willing to follow Chen Wanrong to do the chemical industry.

    Ye Tianheng put down his crutch and said excitedly: "Okay, let's mix it. I'll make the saltpeter. Let's mix ten kilograms first and see, it's seven and a half kilograms of saltpeter." He weighed seven and a half kilograms of potassium nitrate and put it aside.  .

    "I'll make sulfur." ??Kou Yibing said, weighed a pound of sulfur and poured it next to the potassium nitrate.

    Liu Huaide weighed a pound and a half of charcoal and poured them together: "Master Chen, is this mixed?"

    Chen Wanrong nodded and said: "Yes! It must be mixed evenly."

    ¡°No problem!¡± The three of them said in unison, rolled up their sleeves and started mixing with their hands.

    In fact, you don¡¯t have to use your hands, you can also use tools. Chen Wanrong wanted to stop it, but he didn¡¯t have time, so he had to let them go.

    The mixing process is very simple, but the three of them are extremely serious, with solemn faces. After mixing for a while, it is finally ready.

    Looking at the black gunpowder, the three of them could not hold back, and they actually said in unison: "It's time to give it a try!"

    Ye Tianheng said with a smile: "The other day I was making iron shells for my little friend, so I secretly took out two of them, which came in handy."

    Chen Wanrong joked: "Master Ye, okay, you are really not interesting."

    Ye Tianheng was so happy that he said with a smile: "Little things, small things. From now on, I will make you as much as you want." He patted his chest and it was confirmed.

    "Go get it quickly!" Kou Yibing urged.

    Chen Wanrong waved his hand to stop: "It's not possible to try now. We still need to make a fuse."

    "The fuse? How to do it?" Liu Huaide felt very regretful and complained: "Master Chen, you are serious. If you didn't tell us earlier, we would have to wait again."

    Chen Wanrong smiled and said: "If you don't have good gunpowder, you can't do it even if you want to. It's easy to do, just get some cotton thread, oil, linen cloth and moisture-proof agent."

    "Hey, there are a lot of these things." Kou Yibing didn't take it seriously and strode out of the house.  When he turned around, he had all the things he needed.

    Chen Wanrong soaked the cotton thread in oil, dragged it on the gunpowder, and put it outside to dry.  Kou Yibing and the three men acted as they should. Looking at the fuse that had not yet been dried, Ye Tianheng couldn't help but said, "Oh, little friend, are you okay? It's really annoying!"

    Chen Wanrong smiled and said: "Master Ye, don't worry, you can see. Master Ye, now that the gunpowder has been prepared, everything is ready for the artillery. All we need is the east wind, and all we need is your cannon."

    Kou Yibing and Liu Huaide stared at Ye Tianheng and asked in a questioning tone: "Brother Ye, what are you going to do?"
