Infrastructure masters in the red building

Jia Fang took the eldest prince on a "fifteen-hour" tour from Taoyuan Village to the capital, and brought a pack of things back to Taoyuan Village by the way.

This package was prepared by Shuangwen.Earlier, Jia Fang and Shuangwen made an appointment to use a wing room in the courtyard of Daoxiang Village as a "communication location".

There is a "lockbox" in that wing room—the same kind used by the Taoyuanzhai Financial Office to store precious metals.Jia Fang and Shuangwen both know the password, and if they need to hand it over to the other party, or entrust the other party to hand it over, they put it in this lockbox.

This parcel was taken by Jia Fang from the side room when the First Prince was in Daoxiang Village feeling "Fei Chang's house shrinks and misses so much".

He sent the eldest prince back to Wu Yuan, and only then did he have the time to carefully look at the contents of the package.

The things were sent by the shopkeeper Shui Xian, a package of odds and ends, plus a letter.Before Jia Fang had a chance to read the letter, he met Gui Xiaxue.

"Jia Zifang, what good things have you received? Look at you, you have a smile on your face that you can't hide." Gui Xiaxue broke Jia Fang's mood in one gulp, and then entangled him curiously.

"Let's take a look together!" Jia placed it in front of Gui Yaxue, and suddenly had the urge to show off.

He took Gui Xiaxue to the office of the School of Science of Xiaoxiang Academy, where he spread out the package and took out a small cardboard box that didn't look too bright.

Jia Fang opened the carton and pulled out a thin wooden stick, on which a small ball of red special substance was condensed, which was completely dry.And the side of the carton was painted with a layer of vermilion, and there seemed to be one or two light-colored scratches on the coating.

Jia Fang held out the small wooden stick, held it in his hand, and turned to Gui Xiaxue, "Do you smoke cigarettes?"

Gui Xiaxue shook his head like a rattle drum: "Smoking is harmful to health - you said that, now the whole Taoyuan village doesn't smoke, but you coax me to smoke? Are you killing me?"

Jia reassured: That's right——

"Then do you light the oil lamp?"

Gui Xiaxue pointed to the bright skylight: "It's still bright, what oil lamp?"

Jia Fang was helpless, and ordered: "Go get an oil lamp for your experiment."

Gui Xia imitated "Ou" and immediately went to fetch it.He often needs to do experiments in the Faculty of Science, and the most used heating tools are still oil lamps.

Facing the wick of the oil lamp, Jia Fang held a small wooden stick in one hand and a cardboard box in the other, and gently rubbed the tip of the wooden stick in his right hand on the cardboard box, only to hear a "chi" sound, and a small flame burst out The top of the stick rose.Jia Fang then used it to light the oil lamp, and shook his right hand lightly to extinguish the flame at the top of the stick.

"This is..." Gui Xiaxue was stunned for a moment, staring intently at the wooden stick and paper box in Jia Fang's hand, and suddenly said, "Is this candle?"

"Candles?"

"Yes, make candles." Gui Xiaxue went on and on, "According to the history books, the people of Hangzhou in the past cut pine wood into small pieces, which were as thin as paper, and the tops of the wood chips were coated with molten sulfur. Son, it can be used to make fire and replace candles. Isn’t this just a candle?”

Gui Xiaxue carefully pulled out another small wooden stick from the paper box, brought the red cap to his nose and sniffed it lightly, saying, "It's sulfur!"

"Why didn't I think of that?" Gui Xiaxue murmured, "It's so convenient to start a fire with firewood dipped in sulfur! You don't need to smash flint with a fire knife anymore."

Jia Fang shook his head: "Sulphur is not enough, look what it is." He also handed the paper box to Gui Xiaxue, and showed him the coating on the side of the paper box.

Gui Xiaxue sniffed it as usual, but didn't smell anything. After thinking for a long time, he asked, "What is it? It's used to ignite fire? Combustibles?"

Jia Fang replied, "It's red phosphorus, an allotrope of white phosphorus. It's much safer than white phosphorus."

As soon as he explained the general principle of "fazhu", Gui Xiaxue immediately understood, arched his hands to Jia Fang, and said: "I admire, I really admire - if this thing is not called 'fazhu', it should be called What?"

Jia Fang said with certainty: "Matches. Kindling."

You must know that in his time and space, matches were once called Yanghuo and Fanhuo, but they were not made by the Chinese themselves.But in this time and space, he finally had the opportunity to take the lead and make this thing that brought infinite convenience to the people.

"I'll give you a box!" Jia Fang smiled and took a box of unopened matches and gave it to Gui Xiaxue. "You are in an experimental class in the Faculty of Science, so there are more opportunities to use this thing."

Gui Xiaxue thanked Jia Fang, took the matchbox in his hand, and played with it.Jia Fang didn't stop it either, because he knew that this box of matches was absolutely safe, because it was supposed to be called "safe matches".

Gui Xiaxue looked at the matchbox in his hand with a smile, looked at the bare upper and lower sides of the box, and said: "If I were me, I would paste two beautiful small pictures on both sides of this paper box, saying that this 'match' is our Taoyuan. It’s produced in the village. Maybe instead of promoting our Taoyuan Village, it’s okay to promote the beautiful scenery of Wuyuan County!”

Jia Xin gave Gui Xiaxue a big praise in his heart, and praised this kid for his quick brains: Isn't the various beautiful patterns pasted on the matchbox the "sparks" of later generations?He didn't catch up at a young age, but the impression is that the older generation still collects this.

Why does it feel like Shui Xian and Gui Xiaxue are upside down today?Gui Xiaxue inherited Shui Xian's business acumen, but Shui Xian, like Teacher Gui of the Faculty of Science, led people to develop safety matches with great precision.

He then took out a crystal clear glass tube from a long and narrow box, handed it to Gui Xiaxue, and said, "Be careful, this thing is precious and fragile."

When he said this, Gui Xiaxue immediately looked serious, holding the thin glass tube carefully, just about to ask what it is, when he suddenly found out, the frizzy guy immediately shouted: "Look, this tube There's a pillar inside, moving!"

"This thing is so precious." Jia Fang said to Gui Xia, "This glass tube contains mercury, and the rest is evacuated."

For Gui Yaxue, "vacuum" is a state that has been heard but never seen by anyone.At this moment, he opened his mouth to show a "wow" expression, pinched the glass tube with his hand, and then let go, observing the rise and fall of the mercury column inside.

"I see, this is to measure the temperature." Gui Xiaxue concluded.

"Yes," Jia Fang started to read the letter, and told Gui Xiaxue, "Didn't you want to measure the freezing and boiling points of water a long time ago? This thing can help you. But you have to take it easy, this thing can be measured Wen, you must never throw it into a charcoal stove to roast, it will explode..."

Jia Fang threatens Gui Xia to learn.

Gui Xiaxue was as happy as a child, holding the thermometer in his hand and not letting go.

In addition to this precious glass mercury thermometer, Shuixian also sent a few pointer-type manometers along with the package, which were the improved versions of the manometers on the biogas tank in Taoyuan Village—just what Taoyuan Village needed now.

"That's all..."

Jia Fang had gradually forgotten about Gui Xiaxue, and he began to read the contents of Shui Xian's letter to him. Jia Fang couldn't help laughing after watching it.

Shui Xian wrote that he had decided to build a natural village in his Xiaoyuan industrial base, and held a blind date meeting for workers of the right age to find a partner for everyone.As a result, the rumors spread back and forth, and it was said that the object of the marriage was assigned by the boss, and he had to come forward to clarify it quickly, and both parties had to agree...

Jia Fang: Hahahaha...

Once several natural villages were built, the logistical problems that had been criticized before were solved.Some people in the village began to wash, cook, and sew for these workers—not necessarily the family members who did these things, but some people who were too old and not suitable for working in mines or factories began to do these things.

Shui Xian wrote: He did not expect that he paid the miners a wage and indirectly supported many people.

Jia Fang: That's right, to promote employment.

In addition to the package of odds and ends, Shui Xian wrote in the letter that there are also large items. Honeycomb briquettes have already come out, and the boiler Jia Fang wants can also be customized, but it is really impossible for large items. After the children are transported out, we can only wait for the two parties to jointly solve the transportation problem before starting to communicate with each other.

But what Jia Fang wrote in his letter last time, the suggestion of issuing construction bonds, was very appreciated by Shui Xian: "I really can't see it, I can't see it" - Shui Xian wrote on the letter paper, still imitating Jia Fang's Look, hit three exclamation points.

Jia Fang had never taught Shui Xian how to use the punctuation mark, but the other party seemed to have learned the use of the exclamation mark from Jia Fang's tone of writing, and he used it naturally in the reply.

——What a smart person!

Jia Fang couldn't help looking up and thinking about the expression on the corner of Shui Xian's mouth when he wrote the letter.

At the end, Shui Xian wrote casually that the fishing villages by the sea accepted their plan of "relying on the sea to eat the sea". In addition to starting to make ice and sell fresh seafood, they also learned how to catch sea vegetables from the sea. Wash and dry, then sprinkle with condiments, and bake over charcoal fire, it is a delicious snack.Seeing this, Jia Fang couldn't help being greedy——

Unexpectedly, a hand suddenly reached out to his forehead, and Gui Xiaxue's voice sounded: "Jia Zifang, are you alright?"

Jia Fang was startled, and only then remembered that Gui Xiaxue hadn't gone yet, and stayed on the opposite side.

Sure enough, as soon as Jia Fang raised his head, he saw Gui Xiaxue's sparkling eyes.I saw that he deliberately raised the corners of his lips and smiled, but there was not much smile in his eyes.

"Is this letter written to you by that young nobleman who came back from our place last time?" Gui Xiaxue asked across from Jia Fang, and he still didn't forget to stretch out his hand to gesture, "You are so tall, and you look quite upright, as if you are taller than him." You need to look a little better..."

Jia Fang: "Yes... no, wait..."

Gui Xiaxue was obviously referring to Shui Xian, but when Shui Xian came to his Taoyuan village last time, Jia Fang personally accompanied him all day, until the two finally got into a stalemate and the two broke up. He didn't remember seeing Gui Ya Xue ah!If he sees it, Jia Fang will definitely introduce Gui Yaxue to Shui Xian, and tell Shui Xian that Gui Yaxue is his most important brain in the entire Taoyuan Village, and it is completely irreplaceable.

The corners of Gui Xiaxue's lips were raised higher, and he said cheerfully, "You don't remember my appearance at all, do you?"

Jia Fang nodded blankly.

"This is because you couldn't hear me at all when I greeted you!"

The more Gui Xiaxue laughed, the more bitter his eyes became.

Jia Fang suddenly understood, fully understood, from the first time he saw this young man by the Qingfang Bridge, he understood the other party's thoughts completely and thoroughly at the moment.

He was a little flustered: before, he almost regarded Gui Xiaxue as another self, so he never gave the other party's unusual intimacy a clear refusal and rejection.

But now it seems that he and Shui Xian have settled their feud, which made the person in front of him finally realize something.

"This...I'm sorry," Jia Fang panicked immediately, his heart became anxious, and the description became darker and darker, "Well, I'm sorry, I really didn't pay attention to you, I patronized him..."

Gui Xiaxue smiled immediately, and stood up pushing the table with both hands: "It's nothing, I was thinking too much, you just valued me, but I misunderstood your meaning. Now I know!"

He treasured the thermometer in his bosom, and put the matches in his sleeves, and bid farewell to Jia Fang: "Thank you for giving me these two good things today. There will be such a good thing next time, please don't hesitate." Remember to call me!"

With that, he turned and went downstairs.

The office of Xiaoxiang Academy was originally rebuilt from a stilted building, with an extremely wide field of vision.Jia Fang just watched Gui Xiaxue go out.

After this guy left Xiaoxiang Academy, he suddenly stopped and looked up to the sky and shouted: "Ah——"

It seems that the depression in the chest is exhausted for a while.

The sound was not small, and the villagers working in Xiaoxiang Academy looked at him one after another, and the teachers and students in the Xiaoxiang Academy building couldn't help turning their heads to see the excitement.

Gui Xiaxue didn't care, instead he stretched his arms and moved his legs, as if taking this opportunity to finally get rid of the stagnation in his heart, then turned his head, waved his arms vigorously in Jia Fang's direction, and then and left.

Jia placed his silent greeting behind his back, and said in his heart: Learning madman, curious baby, I will always be full of awe and admiration for you.

He is a person who has been educated in a different time and space. His starting point is much higher than that of Gui Ya. Many concepts and knowledge are naturally imprinted in his mind when he received basic education.Gui Xiaxue is different. This person always maintains an open mind and thirst for knowledge, and always pursues all the unknowns tirelessly.

Jia Fang even thought that as long as there is Gui Xiaxue, even without Jia Fang, the world can still go all the way towards a scientific modern society...

——I'm sorry to misunderstand you, it was definitely not my intention.

Jia Fang thought: From now on, he promises not to provoke Gui Xiaxue again.

Jia Fang sent the reply letter to Shui Xian back to Daoxiang Village, and happened to see Shuangwen in that wing.

"Shuangwen? It's a coincidence that there is no need for a safe to pass it on. Just ask you."

Seeing Shuangwen's expression, Jia Fang asked immediately, "Is this a happy event?"

Shuangwen rolled his eyes and said, "Is it a happy event? Naturally, the lady in the mansion and the uncle got married in the field. According to the people who came back from Gusu, the wedding was held grandly and enthusiastically..."

Jia reassuredly thought: Who did you learn Shuangwen from? One set after another? ——He didn't realize that the few people who were close to him, including Li Qingsong and Fuya, all spoke in this way.

When he probed, he saw the scroll behind Shuangwen, and finally guessed it.

"It's the Yihong Courtyard that's been built, right?" Jia Fang saluted Shuangwen, "This time it's all thanks to Sister Shuangwen."

Shuangwen immediately covered his mouth and smiled, then handed the scroll in his hand to Jia Fang, and said, "Thank you, Mr. Jia, for your guidance."

Jia Fang smiled comfortably and said, "Sister Shuangwen, guess what we're going to fix next time."

He remembered that there were not many empty spaces on this scroll.

Shuangwen continued to cover her mouth with a smile, and said with a smile: "I already know, now only Mr. Jia can guess."

Jia Fang was amazed, thought for a moment and asked, "Is it something between Quicui Temple and Qiushuangzhai?"

Shuangwen has never read the original work of the Red Chamber, so it is impossible to predict what will be in the Grand View Garden.Since she already knew it, it must be an item that appeared in the multiple-choice question that was given to the scroll last time.

After hearing this, Shuangwen immediately showed admiration in his eyes, nodded, and said, "Third Master, please take a look."

Jia Fang opened it and found a new courtyard scene painted in ink, but he was not impressed.

"Shuangwen, did you write down every scene that appeared when you did the multiple-choice question last time?"

Shuangwen nodded and said, "I remember that this is Tongjian Qiufeng."

Jia Fang nodded: "That's it, the next project to be built is 'Qiu Shuang Zhai'."

As soon as he finished speaking, letters began to pop out one by one from the blank space of the scroll, and Jia Fang looked at each one:

"B-I-N-G-O-!—"

It's Bingo!
