"What are the two of you talking about here?" Sun Tianhao led Sun Jiayi from behind. Pen, fun, pavilion www. biquge。 info

"Uncle Xu is good, Sister Cheng is good."

"Jiayi is so good." Cheng Yiyi pulled Sun Jiayi to sit down, "Our Jiayi is beautiful again." ”

Xu Lang looked at Sun Tianhao suspiciously: "It seems that the committee didn't give you a holiday." Are you absent from work? ”

"I hid."

"Hidden? What to hide? Cheng Yiyi asked strangely.

"Gao Pengju is back."

"Gao Peng is here?" Xu Lang stood up suddenly, "When?" ”

"Just now, just arrived." Sun Tianhao said with some distress, "Not only did I come back, but I also brought back 2 big ships, which were all the things we needed." Damn, this guy will look for me as soon as he comes ashore. ”

"That's a good thing." Cheng Yiyi asked puzzled, "What are you hiding?" ”

"Hahahaha." Xu Lang laughed loudly, "The cowhide is blowing up." Now that they're back, they're still full of them, and I'll see what you give to them. ”

"You've got to help me figure out how to get rid of him."

"Don't you have a way, no problem, you can do it."

"My own brother, don't be sarcastic about me." Sun Tianhao said with a sad face, "I really can't help it, so I came to you." ”

Xu Lang stopped laughing: "You let me think about it." ”

Cheng Yiyi took Sun Jiayi quietly to the beach in the distance. Xu Lang thought quietly for a while, took out a lighter from his pocket, lit the cigarette that he had been holding in his hand, took a few puffs, and handed it to Sun Tianhao: "You see if this will work, give him salt, let him open the mainland market, and not conflict with Li Shuang." ”

"It doesn't work, I've thought about it." Sun Tianhao shook his head, "The value of the 2 ships he brought, I'm afraid that the salt of 10 ships can't be exchanged, and he will definitely not do it." ”

"That's right. I really can't hack him. ”

"Brother, don't tease me. This line must not be broken, and if you can take Gao Peng down, you don't know how hard I worked. Let's talk about credibility, don't you talk all day long about what era of Song and Ming Dynasty science is now. ”

Xu Lang laughed again: "Look at you, I'm not thinking about it." How is Fan Qiuming's side, what can he come up with? ”

"In the past few days, I have been running to him every day, and the progress is very slow. But listening to what he meant, it seemed that soap and toothpaste were sure. ”

"Really?" Xu Lang patted Sun Tianhao, "Let's go, let's go to Lao Fan's place first." ”

called Cheng Yiyi and Sun Jiayi, and the four of them came to Fan Qiuming's scientific research group together. The research was formed in a clearing with a rock back, surrounded by an earthen wall, and a rudimentary wooden door installed in front of it. As soon as the four people walked to the door, a voice came from inside: "Password! ”

Xu Lang was stunned, why is there a sentry here?

Sun Tianhao hurriedly replied: "Pioneering! ”

The wooden door slowly opened, revealing a young face: "It's Committee Member Xu, Team Leader Sun, please come in." ”

Xu Lang knew this little sentinel, Xu Tianbin, a high school graduate who had just been admitted to college. In order to celebrate the success of the college entrance examination, I sat on the Pearl with a few classmates, but I didn't go to college, but I was able to go to Guozijian.

"Xiao Xu, are you Team Leader Fan here?"

"Yes, it's inside."

Xu Lang walked into the courtyard, opened his throat and shouted: "Lao Fan, Lao Fan, the committee has come to inspect the work, hurry out to greet the leader." ”

Fan Qiuming walked out of a mud house, holding two hands, and he didn't know what he had wiped on his hands.

"Old Fan, old Fan, you're corrupt enough."

Fan Qiuming was stunned: "Where am I corrupt?" ”

"You also said that you are not corrupt, but now how tight the manpower is, you actually made a sentry, you said that you are not corrupt."

Fan Qiuming pointed at Xu Lang with an oily finger: "Xu Lang, let's make a bet." You don't have to wait for the re-election, and your committee members will be dismissed, do you believe it? ”

This time, Xu Lang was stunned: "Why?" ”

"I don't need to ask why, do you know how many people you have offended with this mouth?"

"Haha." Xu Lang laughed and waved his hands, "Others laugh at me for being too crazy, and I laugh at others who can't see through it." I don't see the tomb of Wuling heroes, and there are no flowers and no wine hoeing fields. ”

"Gotcha, gotta gotcha." Fan Qiuming was directly defeated by Xu Lang, "What the hell is going on, I'm still busy." ”

Xu Lang restrained his smile: "It's really serious, Lao Fan, find a place to sit down and talk in detail." ”

Several people entered the house, and Sun Tianhao told Fan Qiuming in detail about the current situation.

Fan Qiuming pondered for a while and said: "There are more than 20 people in our scientific research group, and the task given to us by the crossing conference is to get steel and guns as soon as possible, as for daily necessities, we usually do it in our free time, and now only soap and toothpaste can be said to be technically not too problematic, and other things are not easy to say." ”

"It's been a few months, and you're too slow." Sun Tianhao was a little dissatisfied.

"Team Leader Sun, it's not easy for us, we all started from scratch, not to mention anything else, there are basically no things for experiments now, we all rely on substitutes, we tried our best."

"It's not easy." Xu Lang hurriedly made a round, "Can soap and toothpaste be mass-produced?" ”

"As long as there are raw materials and manpower, it should be fine."

Soap has been around since ancient times, and is said to have been invented by the Phoenicians on the eastern shore of the Mediterranean. Legend has it that in a royal palace in ancient Egypt in the 7th century BC, a Phoenician cook accidentally discovered that the mixture of grease and plant ash had an excellent cleaning effect, which was the earliest soap. Fan Qiuming's research group makes soap according to a simplified modern soap manufacturing process, adding plant ash instead of caustic soda with clean water, heating it over low heat, stirring evenly, and then adding animal and vegetable oils, continuing to heat and stir constantly. Until all the grease has dissolved. Switch to medium and low heat and continue to heat, stirring constantly to make the grease fully saponified. When the stratification appears, add the salt and stir to fully dissolve the salt. Continue heating for a few more moments, stopping the heat and stirring. Cover the pot and let it sit for 3-5 hours before it comes out. When the upper layer of soap is out of the pot, it is the soap base, and the lower layer of sewage can be refined into glycerin, but it cannot be refined at present. With the soap base, add water, plant ash, and rosin to continue to heat, stir constantly, and after layering again, stop heating and stirring, cover the pot, and let it stand for 10 hours before getting out of the pot. At the same time, add flower petals, spices and other substances, stir while adding until well mixed, and then cool and solidify. The simplest bar of soap is all it takes.

Modern toothpaste is to first dissolve spices, active additives, stabilizers, and saccharin in a pre-dissolving pot or pre-mixed pot with pure water until uniform, add them to the paste making pot, and then add the liquid materials in the liquid storage tank to the paste making pot respectively, and then add powder. After the powder is added, spices are added, scraper stirring, homogenizing stirring, grinding, and vacuum is carried out at the same time. The pinch and effect make the paste fully mixed and even, and the grinding purpose makes the paste delicate. After kneading and grinding, it is then injected into the paste storage pot for aging, so that the material is naturally cooled to room temperature, and at the same time, the material is fully expanded to form a homogeneous adhesive to improve the elasticity of the material. The raw materials used to make toothpaste require natural calcium carbonate, dicalcium phosphate, aluminum hydroxide, silicon dioxide, glycerin, sorbitol, sodium lauryl sulfate, and so on. Of course, the scientific research team couldn't get so many modern raw materials, so they could only find substitutes, add some things that can be used now, and barely make the original toothpaste.

Fan Qiuming found two small wooden boxes from a corner of the room and handed them to Sun Tianhao and Xu Lang: "This is the sample that just came out yesterday, and it can only be like this at present." ”

Sun Tianhao opened the wooden box, Cheng Yiyi walked up and sniffed it, frowned and said, "What is this, why is it so weird?" Does this work? ”

Fan Qiuming spread his hands: "The current highest level, don't look at the smell is not good, the effect is not bad." ”

Cheng Yiyi pushed open the wooden box: "With this taste, I might as well brush my teeth with salt." "The modern soap toothpaste carried by the crossing group has basically been exhausted, and many people have begun to learn from the Ming Dynasty to brush their teeth with refined salt, anyway, there is no shortage of salt in Yulin Bay.

Xu Lang suddenly asked, "Yiyi, if this thing smells better and is made more beautifully, can you use it?" ”

"I should be able to use it, but does it smell good?"

Xu Lang didn't answer Cheng Yiyi's question, but asked Fan Qiuming: "Old Fan, can you add more spices, don't use anything else, add flower petals, use floral fragrance to cover up the strange smell, and then make some molds to make different shapes of soap and toothpaste." ”

"That's a good idea." Sun Tianhao became excited, "Let's not talk about whether it's good or not, you have to make it look good first, only buy expensive ones, don't choose the right ones." Brother Xu, you are quite economically minded. ”

Fan Qiuming was a little annoyed by the quarrel of several people, so he had to say: "I'll try it, I can't guarantee that it won't work." ”

"You're sure you'll be fine." Sun Tianhao also learned from the Ming Dynasty and hugged his fists: "Please, Team Leader Fan." ”

"There's one more thing." Fan Qiuming stopped Xu Lang, who was about to say goodbye, "I'm too busy to leave now, when you have a committee meeting, you mention that our scientific research group wants to start a hydropower project." ”

"Electricity?" The eyes of the three men widened at the same time.

"Why do you want to eat people." Fan Qiuming said with a smile, "All the things we have now are made by hand with the most primitive technology, not to mention standardization, this efficiency is too slow, we have to take the road of coal and iron, and we must generate electricity." ”

"Hydraulics shouldn't be a problem, but can you build a generator?" Xu Lang didn't believe Fan Qiuming's words.

"That's why I'm looking for you." Fan Qiuming smiled evilly, "I have carefully looked at the two boats, there is not only one generator on them, but also some simple drilling machines and machine tools, these are the basic configuration of the ship, and it is useless to put them there now." I asked Nie Zhongbin, although it is more troublesome, diesel generators can still be transformed into hydroelectric generators, and those drilling machines and machine tools can also be used. ”

"You're going to dismantle the ship." Xu Lang said, "I'm afraid that the committee can't make the decision on this matter, and it has to go through the conference to decide, and it's useless for you to find me." ”

"I know this, you go and breathe first, and see their opinions."

"Ventilation is fine, though." Xu Lang also smiled evilly, "I can't guarantee that it won't work." ”
