The guests and guests had a great time having this supper. Wu Da raised his glasses frequently and toasted Su Hao. Su Hao had insufficient experience on the table and could not resist Wu Da's enthusiasm. Finally, he was tragically poured down and was carried back home by Wu Daniu and Lu Xiu'er.

The next day, Su Hao slept until half a morning before he woke up dizzy. He sat on the bed, rubbed his eyes, and shouted loudly: "Xiu'er, Xiu'er!"

"Brother, are you awake?" Lu Xiu'er responded. She didn't drink the first day, got up early in the morning, and was cleaning the inside and outside the house.

"When is it now?" Su Hao asked.

Lu Xiuer said: "It's past the Si time."

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

Lu Xiu'er looked innocent: "You didn't ask me to 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 couldn't get up."

"It's broken, the image of the leading cadre is over." Su Hao hurriedly wore his clothes.

Lu Xiu'er leaned forward and asked while combing Su Hao's hair, "Brother Hao, didn't you sleep until noon every day before you get up? Now it's Si Shi, why are you anxious?"

Su Hao smiled bitterly and said, "Girl, that's good in the countryside. Now I'm a civil servant at least, so I have to get up early. Remember that I'll wake me up early in the morning and be late every day. The magistrate must fire me."

After tiring up, Su Hao rushed to the kitchen, grabbed two pieces of rice cakes that Lu Xiu'er had fried, and ran out and ran outside the door. Then he remembered and turned around and shouted 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 tonight. If I don't come back, you can go to Wu Da's house to live."

"Okay." Lu Xiu'er responded crisply.

Su Hao ran to the county government all the way. As soon as he passed the small stone bridge in front of the county government government, he saw the dozen or so students who had trained yesterday waiting for him in the open space.

Because Su Hao had already informed everyone that he would go to the countryside to do things the day before, everyone did not wear a silly shirt, but changed into blue cloth shirts and pants like ordinary people, and they were wearing thick-soled blue cloth shoes, which looked more energetic than before. Everyone was carrying a big bag, including changing clothes, pens, ink, paper, and inkstones. There were several good-family students who also brought servants.

"Sorry, sorry, brothers, I'm accustomed to work as a job for the first time, I don't have the habit of getting up early, I've been tired of waiting for a long time." Su Hao apologized to everyone.

"Brother Gaizhi is polite. Just now, the runner of Wu Yabo has already told you that after you left the county yard yesterday afternoon, you went to Wu Yabo's house to discuss the techniques of a firewood stove with him until the genius returned home at the third hour. Brother Gaizhi's spirit of seeking truth is worth learning from us." The scholar Ma Yu walked up and said politely to Su Hao.

"Ahem, this is all right, it's right." Even though Su Hao had two lifetimes of experience, his face turned red at this time. Fortunately, before going out in the morning, he chewed a few sips of tea to cover the remaining smell of wine in his mouth. Otherwise, Ma Yu and others would smell the smell of wine in his mouth, and combined with his lateness, his image as a leading cadre would really fall to the ground.

"Dear brothers, everyone has to wait here for a while. I have to go to the workshop to explain some things. In addition, I have to report some things to the magistrate. I would like to bother you to wait patiently for a while." Su Hao said.

"Brother Gai, go, let's go, I'm here, and I'll try to learn about the way to investigate things I learned yesterday." Everyone said to Su Hao together.

Su Hao hurried into the county yard. He came to the workshop first. Dai Qi and the yamen runners were waiting for him. When they saw him coming in, everyone saluted him together.

Su Hao bowed to everyone as a gift, and then said to Dai Qi: "Old Dai, I discussed the issue of saving firewood with Wu Da last night, and it was too late that I forgot a big thing. Now I am about to take people to the countryside to dig wells, so I have to ask you to handle this matter."

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

Su Hao walked to the table, took a few pieces of paper, picked up the charcoal strips left over the past day, and began to draw pictures on the paper. While drawing, he explained to Dai Qi: "Old Dai, there are a few things we need to use in the countryside. Please find someone to make them. One is a tripod, which looks like this..."

As a person who has been conducting surveys for many years, Su Hao has no idea about his ability to draw a drawing. He draws a charcoal strip with a random drawing, and he almost has the effect of regular mechanical drawing. There are yamen runners who are carpenters and blacksmiths in the workshop. When they stand by and look at the drawings, they know what Su Hao wants to do. However, no one has seen these things before, and they don’t know what they are for.

"These are surveying and mapping instruments. You can prepare according to 15 sets first. How long will it take to do it?" Su Hao asked Dai Qi.

Dai Qi looked back at the yamen runner standing beside him. A yamen runner named Xie Sizhi quickly replied to Su Hao for him: "Sir Su, the young man is a carpenter. The carpenter work here is the young man, and the younger man is responsible for arranging people to do it. It can be done in two or three hours."

Another yamen runner named Jiang Youbao was from a blacksmith. He roughly estimated that the iron tools could be finished in only two or three hours.

"Okay, then please let me go and handle it quickly. After it is made, I will send someone to Dengxian Township. We will explore the well there today." Su Hao said.

"Don't worry, Master Su." The two yamen runners took the pictures and walked out in great strides.

After explaining the production of surveying and mapping instruments, Su Hao called Dai Qi and Wu Da and went to the lobby of the county government to meet the county magistrate Han Wen.

There was no complaint in the lobby today. Han Wen was sitting aside with Fang Mengjin having tea and chatting. When he saw Su Hao and others coming in, Han Wen laughed and said, "It's changed, listen to Qian... Uh, I heard from the master that you taught the theory of studying things yesterday, which was very exciting."

"Mr. Han has a too much award." Su Hao said, "Mr. Han, Master Fang, the students and the students of the academy have made an appointment. Today I will go to the countryside to explore the well. Now I am here to say goodbye to Master. Han and Master Fang."

"It's been a hard time to reform. When you come back from the countryside, let's set up wine and dust for you." Han Wen said.

Su Hao said: "Mr. Han, before the student goes to the countryside, he wants to report something to the adult, and he also asks for support."

"What's the matter?" Han Wen asked.

Su Hao said: "Yesterday, the student, together with Dai Shuli and Wu Yayi, combined with the principles of thermodynamics of Westerners, developed a kind of firewood-saving stove. After our tests, we were sure that it could save more than half of the firewood, and a family of four could save fifteen pounds of firewood a year. The students came to report this to the adults and the master."

Han Wen frowned, but did not express any dissatisfaction, but just said, "Oh, I know about this."

Fang Mengjin heard the meaning of Han Wen, and said to Su Hao: "In order to change it, the most important thing in the county nowadays is to dig wells. This is just a trick to save firewood and stoves. You don't have to put too much effort into such things."

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

"Tell me." Han Wen said expressionlessly. He was very unhappy with Su Hao reporting such trivial matters to him, but thinking that Su Hao was about to go to the countryside to dig wells, this was a major matter, and it was not convenient for him to refute Su Hao's face at this time.

Su Hao said: "Mr. Han, Master Fang, students think that saving firewood is a very important invention. According to students' understanding, farmers in the county currently use traditional soil stoves, which consume a lot of firewood and grass. The straw produced in the fields is not enough. Many farmers also have to cut branches to fill firewood. Students consider that if we can promote this firewood stove in the county, then every household will not only not have to spend time collecting additional firewood, but also the straw can be saved. Whether it is used for fermenting fertilizer to return the fields or for raising cattle, it is very beneficial for ordinary farmers."

"Promote in the whole county?" Fang Mengjin thought, and he faintly understood Su Hao's meaning. As a master, he was not unfamiliar with the world. He could imagine that if this kind of stove could really save half of the firewood and was promoted in the whole county, the impact would be great.

Since ancient times, rural areas in the south have known the principle of returning straw to the fields. However, the straw is not enough to burn, so few families can do it. If farmers can have excess straw for returning the fields after promoting firewood stoves, they will play a great role in promoting agricultural production. No one doesn’t like this kind of profitable and easy political achievements.

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

Su Hao said: "What I want to report to Lord Han now is one of our workshop's ideas on promoting firewood stoves. We have calculated that according to the calculation that can save half of the firewood stoves, a family of four can save no less than five cents of firewood in a year. We plan to charge the people at one cent per stove, and I believe that any family will be very willing to adopt it. We plan to train a group of plasterers and use a year to popularize firewood stoves in the whole county."

"One qian per stove is indeed not expensive." Han Wen also understood, and he nodded and said, "What name do you plan to promote it?"

Su Hao said: "It's very simple. We promote it in the name of the county government. This kind of stove can save money for the people, and the price of building stoves is very favorable. This is definitely a great thing for the people. After we discussed that for every stove promotion, we can pay two cents of silver to the county government. If 30,000 households in the county renovate firewood stoves, we can pay 600 taels of silver to the county government."

"Haha, there is no need for this. Just leave this money in the workshop." Han Wen understood what Su Hao meant, and the unhappy expressions on his face disappeared. He laughed and waved his hand and wiped out the management fee for Su Hao. For Han Wen, what is more important is to generate political achievements. This amount of money is not within his eyes.

"Change it, does this stove you designed have a name?" Fang Mengjin asked intentionally or unintentionally.

"This stove..."

Su Hao was about to say that the stove was called Jianchai Stove. Dai Qi, next to him, interrupted him and went up to Han Wen and said, "Report to Lord Han, Master Su and the young people have discussed it together. We want to name the stove Han's Jianchai Stove. Please ask Lord Han to agree."
