"Sir, is there something wrong?" Seeing Lu Chen tapping his fingers as if calculating something, Su Chang couldn't help but ask with confusion.
"Ah? It's nothing. I'll send the things over in three days!" When Su Chang asked, Lu Chen immediately came to his senses, looked at Su Chang and smiled slightly.
"Yes!" Su Chang saluted and left the front hall.
As Su Chang left, Lu Chen reached out and touched a pistol hidden in his waist. He felt a lot more at ease, and the unsettling feeling he had just now also alleviated a lot, "Is it a blessing or a curse? , there is no way to avoid disaster." Lu Chen touched the pistol on his waist, his eyes became firm, "I want to see what this ominous feeling is about!" Lu Chen stood up directly and left the front door. He walked into the hall and went straight to the study. He was going to study the salt farm now.
Lu Chen was already familiar with making salt. After all, he had taught Lao Huang how to make alcohol and saline when he was in the Women's Army. However, the situation this time was slightly different from that in the Women's Army. The Women's Army used coarse salt. This time the target is those poisonous mineral salts.
Lu Chen was reading a book for a while to study how to remove the toxicity of poisonous mineral salt, and then he discovered that turning poisonous mineral salt into ordinary table salt was just one more step. Just this one step stumped Lu Chen. Originally, Lu Chen He thought he had found a treasure, but when he saw what he needed, Lu Chen's mentality exploded because one thing was needed to remove toxins, and that was "activated carbon".
"Activated carbon" is a product of the 20th century. It seems unrealistic to make this thing by hand in this era, because making this thing requires a piece of equipment. Even if Lu Chen rummaged through the entire base, he might not be able to do it. Find this thing, it is the "pyrolysis furnace".
"How can this be done!" Lu Chen, who was sitting in the base looking for a method in a book, couldn't help but start scratching his head. Without activated carbon, it would be troublesome to use poisonous salt to remove toxins.
Just when Lu Chen was at a loss what to do, Lu Chen suddenly saw a book. Lu Chen had read this book before. It contained a lot of knowledge about hand-making. Lu Chen's extraction of alcohol and physiological saline was from This book came to school. Lu Chen looked at the book and thought for a while. Lu Chen suddenly remembered that he seemed to have seen an introduction to charcoal or some kind of charcoal in this book, but at that time it was just to look up alcohol and physiology. Salt water and others have not been noticed. Now Lu Chen can only put his hope in this book.
When he saw "How to make your own activated charcoal", Lu Chen immediately felt happy. After reading how to make activated charcoal, Lu Chen frowned slightly. It seemed that he still needed a lot of things!
Fortunately, among other advantages of this era, the biggest advantage for a distinguished person like Lu Chen is that the people in Lujiazhuang will work for him as long as he gives an order.
Lu Chen left the base and returned to reality. He also took out the book and started writing on the paper how to make activated carbon.
In fact, it is not complicated to make your own activated carbon. First, make all the charcoal into pieces of about one square centimeter, then put it into a mesh bag, then put it into the sodium carbonate solution and boil it for about thirty minutes. Sodium carbonate is the name of the book, but in fact the sodium carbonate solution It is alkaline water. Alkali can be purified directly from alkali ore.
After doing this, wash the cooked charcoal blocks with clean water, then boil them with 5% sodium carbonate solution for 30 minutes. At this time, take out the charcoal blocks and wash them three times with clean water. Clean them thoroughly. , after all this is done, you can put this bag of processed carbon blocks outside to dry. After drying, you will get a homemade version of activated carbon.
"Huh!" Lu Chen wrote down the method of making "activated carbon" in one breath, then he breathed a sigh of relief and rubbed his sore wrist.
"Dog!" Lu Chen opened the study door and shouted. Liu Jing, who was reading in the side room, heard Lu Chen calling him and ran out quickly.
"Go and call you Aye, I have something to ask him for!" Lu Chen ordered Liu Jing.
After Liu Jing responded, he turned around and quickly went to find his father.
Lu Chen turned around to go back to the study, and then suddenly found Feng Huai sitting next to the study door. This guy was half as tall as a man. Just now, Lu Chen opened the door and called Liu Jing without noticing Feng Huai. This sudden sight Such a big lump of stuff immediately startled Lu Chen.
"I'll go!" Lu Chen glanced at Feng Huai, "Feng Huai, why are you sitting here? The ground is so cold!" Lu Chen looked at Feng Huai with concern.
Normally, when Lu Chen was in the study, Liu Jing would be reading and waiting in the wing, while Feng Huai would be wandering around the yard. This guy rarely had any free time.
It is so unusual to be so unusual today, sitting at the door of his study.
Feng Huai responded and then stood up.
"Is something wrong?" Lu Chen looked at Feng Huai and asked while helping Feng Huai dust the dust on his back.
"No!" Feng Huai shook his head, "Master Gouwa has something important to do in the study. He asked me to stay here, so I'll stay by the door!" Feng Huai bared his teeth at Lu Chen and said with a smile.
"Don't do this next time! Even if you have to sit at the door, you have to find a stool, you know? It's so cold on the ground!" Lu Chen looked at this silly guy and asked with a bit of laughter and tears.
"Hey! I remember it!" Feng Huai nodded.
"This kid..." Lu Chen shook his head helplessly. This fool just met him. If it were another person, he wouldn't know how to bully this kid!
Not long after, Liu Laosan was led by Liu Jing to the study.
"Lao San, has anything happened in the workshop area recently?" Lu Chen looked at Liu Lao San and motioned Liu Lao San to sit down. Liu Lao San still looks like the former Detachment of Women blacksmith, and his clothes have also changed from burlap clothes. , has been upgraded to coarse cloth clothes, his face is a lot rosier, and his figure is not too out of shape. After all, there are many things in the arsenal that require his own hands.
"Thank you, Mr. Gong, everything is as usual, except that there are many more children from farmers' families who want to work in the workshop area!" After Liu Laosan thanked Lu Chen, he sat on a chair next to him. And Liu Laosan only dared to sit half-assed, and after hearing Lu Chen's question, he reported to Lu Chen.
"Yes!" Lu Chen nodded, "Those children who are willing to learn some crafts can help in the workshop area. Of course, you must keep an eye on them and don't let them approach dangerous places!" Lu Chen warned Mr. Liu San Yi said, "Also, don't let those half-grown people go to places like the Arsenal and Liulicang!"
On the one hand, the arsenal is Lu Chen's secret. Lu Chen doesn't want too many people to know. Those grown-ups are not very strict with their speech. It's always a troublesome thing if they get out naked. On the other hand, inside Liulifang, They are all fragile things. If those things are broken, it doesn't matter. At most, they can be remade. If those dishonest adults take those pieces out to play and hurt others and themselves, it is not a good thing. .
Therefore, Lu Chen didn't want those half-grown men to go to these two places to mess around. As for the printing shop, Lu Chen estimated that not many half-grown men would be willing to go to such a boring place.
"Yes!" Liu Laosan responded again.
"By the way, and after the New Year, I will drive all those half-grown children out of the workshop area and let them all go to school! You have to tell them in advance about this. If any of them doesn't want to go to school, they will not even work. They won't let him in, you know?" Lu Chen warned Liu Laosan again, and Liu Laosan agreed again.
"Master, you seem to value those children very much?" Liu Laosan still asked his doubts. After listening to Lu Chen's words, Liu Laosan felt that his father-in-law cared about them more than the farmers themselves. children.
"Of course, these children are different from you and me. They are the future of Zhuangzi!" Lu Chen picked up the tea cup and took a sip of tea, "Not far away, just you. A hundred years from now, you will still have Gouwa is wearing sackcloth and mourning for you, don't you want Gouwa to get ahead?" Lu Chen looked at Liu Laosan and asked with a smile.
"Gouwa is now more promising than this old man like us!" Liu Laosan replied with a very honest smile.
"Now I let Gou Wa study, so that Gou Wa can be independent in the future, and she doesn't have to be by my side all the time!" This is the first time that Lu Chen told Liu Laosan about his plans for Liu Jing's future.
"Master, don't you want the dog baby anymore?" After hearing Lu Chen's words, Liu Jing's face suddenly turned pale, and he knelt down with a "pop" and looked at Lu Chen crying.
"What are you doing!" Lu Chen was startled by Liu Jing's sudden move, and then scolded Liu Jing, "How many times have I told you, the man has gold under his knees, but you can't kneel down." Master, why are you kneeling down all of a sudden? Why don't you get up?"
"Master, do you no longer want the dog?" Liu Jing seemed not to have heard Lu Chen's scolding, and asked again with a tearful voice.
"Hu Yao! When did I stop wanting you! Get up quickly!" Lu Chen put down his tea cup and glared at Liu Jing.
"Then you just..." Liu Jing heard that Lu Chen didn't want him, so he stood up and muttered.
"What's wrong with me?" Lu Chen glared at Liu Jing again, "Are you just going to squat in this Lujiazhuang all your life? I have no intention of staying here all my life. My fiefdom will definitely be very big in the future. Don't you have to Help me manage it! If that's the case, then I really don't want you anymore!" Lu Chen was so angry and happy at Liu Jing's slutty look that he glared at Liu Jing.
"I will definitely study hard and I will never let you go! That's right, sir, wherever you go from now on, I will go!" Liu Jing vowed.
