This dinner, the guests and hosts had a very good meal. Wu Da frequently raised his glass and toasted Su Hao. Su Hao's lack of experience at the wine table couldn't hold Wu Da's enthusiasm, and finally he was tragically poured down, and was sent home by Wu Daniu and Lu Xiu'er.

The next day, Su Hao slept until mid-morning before waking up dizzy. He sat on the bed, rubbed his eyes, and shouted loudly, "Xiu'er, Xiu'er!" ”

"Brother, are you awake?" Lu Xiu'er arrived, she hadn't drunk the first day, she got up early in the morning, and was cleaning the inside and outside of the house.

"What time is it?" Su Hao asked.

Lu Xiu'er said: "It's past time. ”

"The time!" Su Hao was stunned for a moment, slapped his head suddenly, and jumped out of bed, "Wow, it's more than 9 o'clock, and I asked the students of the academy to go to the county office early in the morning to wait for me to go to the countryside together!" Xiu'er, why didn't you call me? ”

Lu Xiu'er looked innocent: "You didn't let me call you." Besides, you drank so much wine last night, and there was still a smell of alcohol in the house in the morning, I thought you wouldn't be able to get up. ”

"It's broken, it's broken, and the image of leading cadres is over." Su Hao hurriedly got dressed.

Lu Xiu'er stepped forward and asked while combing Su Hao's hair: "Brother Hao, didn't you have to sleep until noon every day in the past to get up, and now it's only time, what are you anxious about?" ”

Su Hao smiled bitterly: "Sister, is it good to be in the countryside, now my brother is also a civil servant, so I have to start early." In the future, I remembered that I had to wake up early in the morning, and if I was late every day, the magistrate had to fire me. ”

After hurriedly freshening up, Su Hao rushed to the kitchen, grabbed two pieces of Lu Xiu'er's fried rice cakes, and ran out to the door, only to remember to turn around and shout to Lu Xiu'er: "Xiu'er, I want to take the students to the countryside today, and I may not be able to come back at night." If I don't come back, you can go to Wu Da's house and stay. ”

"Okay." Lu Xiuer responded crisply.

Su Hao trotted all the way to the county office, and just after crossing the small stone bridge in front of the county office, he saw that the dozen or so students who had been trained yesterday were waiting for him in that open space.

Because Su Hao had notified everyone to go to the countryside to do things the day before, everyone did not wear shirts, but changed into green cloth shirts and pants like ordinary people, and the blue cloth shoes with thick soles under their feet looked more energetic than before. Everyone carried a large bag, which contained a change of clothes, as well as pen, ink, paper, inkstone, etc. There were a few well-paid students, and they also brought servants.

"I'm sorry, I'm sorry, brothers, my little brother is on an errand for the first time, and I don't have the habit of getting up early, so I'm tired of waiting for you." Su Hao arched his hands to everyone and apologized.

"Brother Gaizhi is polite, the appropriate talent Wu Ya Shi has already come to tell you, saying that after you left the county government yesterday afternoon, you went to Wu Ya Shi's house to discuss with him the techniques of a provincial firewood stove, until the third watch did not go home. The truth-seeking spirit of Brother Chang is worth learning from my generation. Xiucai Ma Yu stepped forward and said politely to Su Hao.

"Ahem, this is all as it should be, as it should be." Rao is Su Hao has the experience of being a human being in two lives, and he can't help but blush at this time. Fortunately, before going out in the morning, he chewed a few sips of tea leaves, which was considered to cover the residual taste of wine in his mouth, otherwise, let Ma Yu and others smell the wine in his mouth, combined with his lateness, his image as a leading cadre would really fall to the ground.

"Brothers, you still have to wait here for a while, I still have some things to go to the workshop to explain, in addition, I have to report some things to the magistrate, please wait patiently for a while." Su Hao said.

"Brother Change, let's go, I'll wait here, just to learn the way of Gewu that I learned yesterday." Everyone said to Su Hao together.

Su Hao hurriedly entered the county office, he came to the workshop first, Dai Qi and the officials were also waiting for him, and when they saw him come in, everyone saluted him together.

Su Hao arched his hand to everyone, which was regarded as a return salute, and then said to Dai Qi: "Old Dai, I discussed the matter of saving firewood stoves with Wu Da last night, and it was too late to forget a major event. Now I'm going to take someone to the countryside to dig a well, and I'll ask you to take care of it. ”

"Master Su, please speak." Dai Qi said respectfully.

Su Hao walked to the table, took a few pieces of paper, picked up a piece of charcoal left over from the previous day, and began to draw on the paper, explaining to Dai Qi while drawing: "Old Dai, there are a few things like this, which we need to use when we go to the countryside, please find someone to make them." One is a tripod, and it looks like this......"

As a person who has been engaged in surveying all year round, Su Hao's cartographic ability is not to be said, he takes a charcoal strip and draws it casually, and it almost has the effect of regular mechanical drawing. There were carpenters and blacksmiths in the workshop, and when they stood next to them and looked at the drawings, they knew what kind of things Su Hao wanted to make, but everyone had never seen these things, and they didn't know what they were for.

"These are all surveying and mapping instruments, you prepare them according to 15 sets first, how long do you estimate it will take to do it?" Su Hao asked Dai Qi.

Dai Qi looked back at the official standing beside him, and a servant named Xie Sizhi hurriedly replied to Su Hao for him: "Master Su, the little one is a carpenter, and the carpentry work here is responsible for arranging people to do it, and it can be done in two or three hours." ”

Another servant named Jiang Youbao, who was a blacksmith, made a rough estimate and said that it would only take two or three hours to complete the ironwork.

"Okay, then trouble the two of you to do it quickly, and after it is made, send someone to Dengxian Township, where we will investigate the well." Su Hao said.

"Master Su rest assured." The two officials took the map and strode out.

After explaining the matter of making surveying and mapping instruments, Su Hao called Dai Qi and Wu Da and came to the lobby of the county government together to see the county Hangul.

No one complained in the lobby today, Han Wenzheng and Fang Mengjin were sitting on the side drinking tea and chatting, and when they saw Su Hao and others coming in, Han Wen smiled and said, "It's changed, listen to Qian...... Well, I heard my master say that you taught the theory of Gewu yesterday, which was very exciting. ”

"Lord Han has won the prize." Su Hao said, "Master Han, Master Fang, the students and the students of the academy have made an appointment to go to the countryside today to survey the well, and now they have specially come to bid farewell to Lord Han and Master Fang." ”

"It's hard to change, when you come back from the countryside, the county will give you wine and wash the dust." Han said.

Su Hao said: "Lord Han, before the students go to the countryside, there is something I want to report to the adults, and at the same time, I want to ask the adults to support them." ”

"What?" Han Wen asked.

Su Hao said: "Yesterday, the students, together with Dai Shuzhi and Wu Yazhi, combined with the thermodynamic principles of Westerners, studied a provincial firewood stove. After our tests, we are sure that more than half of the firewood can be saved, and a family of four can save 15 loads of firewood a year. The students came to report the matter to the adults and masters. ”

Han Wen frowned, but didn't express any dissatisfaction, just said, "Oh, this county knows about this." ”

Fang Mengjin heard the meaning of the Korean language, and he said to Su Hao: "Change, the most important thing in the county now is to dig a well, and the matter of this provincial firewood stove is just a small skill of carving insects, you don't have to put too much thought into such things." ”

Su Hao said: "Master Han, Master Fang, please allow the students to finish their words." ”

"Say it." Han Wen said expressionlessly, he was very unhappy with Su Hao's report to him about such a trivial matter, but thinking that Su Hao was about to go to the countryside to dig a well, this was a matter of great importance, and it was inconvenient for him to refute Su Hao's face at this time.

Su Hao said: "Master Han, Master Fang, the students think that this provincial firewood stove is a very important invention. According to the students' understanding, at present, the farmers in the county are all traditional earthen stoves, which consume a lot of firewood and grass, and the straw produced in the field is not enough, and many farmers have to cut down branches to replenish firewood. The students considered that if we could promote this kind of firewood stove throughout the county, not only would every household not have to spend energy to collect additional firewood, but also the straw would be saved, whether it was used for manure returning to the field or for raising cattle, which would be of great benefit to ordinary farmers. ”

"Promote it all over the county?" Fang Mengjin's heart moved, and he vaguely understood what Su Hao meant. As a master, he is not a person who does not eat fireworks in the world, he can imagine that if this kind of stove can really save half of the firewood, and it is also promoted in the county, this impact is indeed very great.

Since ancient times, the southern countryside has known the truth of returning straw manure to the field, but it is difficult to burn enough straw, so few people can do it. If the promotion of firewood stoves is promoted, farmers can have surplus straw for returning to the field, which will play a great role in promoting agricultural production. This kind of political achievement that benefits but does not cost anything, how can anyone not like it.

"How can you do it to the whole county?" Fang Mengjin asked.

Su Hao said: "What I want to report to Lord Han now is an idea of our workshop on promoting the provincial firewood stove. We have calculated that according to the calculation that the firewood stove can save half of the firewood, a family of four can save no less than five dollars of firewood and grass in a year. We are going to charge the people one penny per stove, and I believe that any family will be more than willing to adopt it. We plan to train a group of plasterers and use one year to popularize provincial firewood stoves throughout the county. ”

"It's not expensive to pay a penny of silver per stove." Han Wen also understood, he nodded and said, "What kind of name are you going to promote?" ”

Su Hao said: "It's very simple, we promote it in the name of the county government, this kind of stove can help the people save money, and the price of the stove is very favorable, which is definitely a great thing for the people." We have discussed that for every stove promoted, we can pay a management fee of two cents of silver to the county government. If there are 30,000 households in the county to renovate the provincial firewood stoves, then we will be able to pay a management fee of 600 taels of silver to the county government. ”

"Hehe, it's not necessary, just leave the silver in the workshop." Han Wen understood what Su Hao meant, and the unhappy expressions on his face suddenly disappeared. He smiled, waved his hand, and wiped out the management fee to Su Hao. Promoting the provincial firewood stove, for Hangul, is more important to be able to produce political achievements, which is not in his eyes.

"Change, do you have a name for this stove you designed?" Fang Mengjin seemed to ask intentionally or unintentionally.

"This stove ......"

Su Hao was about to say that this stove is called the Provincial Firewood Stove, but next to Dai Qi interrupted him, stepped forward and said to Han Wen: "Lord Qiqi, Master Su has discussed it with the little ones, we want to name this stove Han's Provincial Firewood Stove, and ask Lord Han to agree." ”
