A new teacher has come to Lishuping, and he will give a lecture every few days, talking about things that only students in big cities have the opportunity to learn.

From a dozen or so children at the beginning, to the children near a small mountain col, this small village class finally gathered enough 20 people.

From the first day of class, the children were fascinated by the teacher's set of things. What kind of biogas can be ignited, a magnet that can suck away iron nails, and that very good song, although I don't understand the meaning of the song, everyone thinks this teacher is amazing.

"The sun shines in the sky, the flowers smile at me, and the birds say they ...... early"

A group of children sang their newly learned nursery rhymes, walked around the village and played hide-and-seek, and just happened to meet Zhang Shusheng, who was carrying a basket of stones back to the village, and several children rushed forward to say hello.

"Hello Mr. Zhang!"

"Hello students, be careful, don't fall."

Looking at the children who were very happy despite their faces, Zhang Shusheng felt that he had returned to the modern era, and smiled and broke away from the group of children, but two slightly older children came over, "Teacher Zhang, let's help you carry it." ”

"How can this work?" Zhang Shusheng's back basket is all ore, how can the two children afford it. These two children are the most spiritual surnames in the village, one is named Chen Jun and the other is Zhao Ziyun. They and the child named Zhu Zijian on the col are the three most potential children in Zhang Shusheng's class.

Chen Junsheng's surname is taciturn and doesn't like to speak, while Zhao Ziyun, on the contrary, likes to ask everything clearly. He is about the same surname as Zhu Zijian, he thinks deeply about things, and he always likes to ask this teacher who seems to know everything when he doesn't understand.

Chen Jun and Zhao Ziyun didn't let Zhang Shusheng continue to carry it, and the two of them took the back basket one by one, one of them couldn't carry it, and the two of them carried it just right.

In order not to disturb Zhang Shu's usual reading, Sun Changqing specially changed the back of the house to become a backyard, with stones taken from local materials and trees in the village, but it was quiet. Zhang Shusheng didn't open the backyard door, and the Sun family would never disturb him. As for the usual meals, the village provided them together, and it didn't make Old Man Sun's family too expensive.

Carry this ore, which is obviously not an ordinary stone, back to the backyard, close the door and take out the dream machine. At this time, the Dream Machine has already opened the village-level function, in addition to the primary item manufacturing, there is also primary technology, and can provide mineral identification and other primary database functions.

Zhang Shusheng picked up a piece and put it in front of the dream machine, activated the comparison and recognition function of the database, and the name was immediately displayed on the remote control: phosphate rock, use, preparation of phosphate fertilizer, as well as medicine and food......

Unexpectedly, it was phosphate rock, Zhang Shusheng was a little overjoyed. Although he knew that the mountain behind the village was exposed to a kind of ore, he didn't expect it to be such a practical ore. Judging from the identification analysis on the dream machine, this phosphate rock can be made into crushed ore powder, which is a basic phosphate fertilizer.

Nitrogen grows branches, potassium grows roots, and flowers and fruits are sprayed with phosphorus, this sentence is the only crop knowledge that Zhang Shusheng, who is a farmer, can remember, and it happens to be there.

Lishuping is a typical southwest village, the soil quality is actually very good, if there are good seeds and good fertilizer, not to mention a bumper harvest, at least full food is not a big problem.

In the past few days, Zhang Shusheng has begun to teach children the basics of modern science, and last time he actually found a magnet mine, although it was very small, but it made him make a simple magnet. I didn't expect it to be phosphate rock this time.

In addition to attending classes, he has actually been preparing for the beginning. The county seat needs to be visited, and some things also need to be excused to get out.

Zhang Shusheng told Sun Changqing that he wanted to go into the city to buy something and buy some simple teaching supplies, and the old man also supported it, but said that the world was not good, and he couldn't let the weak Zhang Shusheng go alone, so he asked Sun Laixi to go with him.

After one night's hard work, Zhang Shusheng actually prepared everything.

He found that if he imitated something simple with a template and raw materials, the dream machine could be imitated with almost no energy. After finding some metal and using his own watch as a template, the Dream Machine used very little energy to create three watches that looked like brand new watches at first glance. As soon as the strap is thrown away, the lanyard becomes an alternative pocket watch.

There is only 15% of the energy left in the village-level system, and Zhang Shusheng has to use it tightly.

The most needed for synthesis are food crops. However, Zhang Shusheng also had an extra heart, and he didn't get too much, so he synthesized a thing, potatoes. However, this potato is not a shriveled small potato grown in the countryside at that time, but a good potato with a yield of two or three times larger. Even if the fertilizer factor and planting method are considered, the yield is definitely much better than the varieties planted in the current pear tree.

Originally, it was a total of 30% of the energy, 15% was used, and now a little potato seed has been synthesized, Zhang Shusheng looked at it, good guy, only 5% is left. It is estimated that if you synthesize it again, the current energy will be gone, and it seems that you have to find a way to improve your strength as soon as possible, and you can't be a teacher forever.

In the end, from the primary technology in the dream machine, I found two copies of the details of the science and technology plan and copied them, plus the pistol that never left me, and then I set off with Sun Laixi.

Usually go into the mountains to look for minerals, Zhang Shusheng occasionally practiced pistol marksmanship, rabbits did not hit a few, but the marksmanship has improved a lot, and the shooting of stationary objects within 50 meters is still quite accurate.

There are two reasons for bringing Sun Laixi, one is that there is a follower, and the other is that the road is not very smooth, this short twenty or thirty kilometers of mountain road, in addition to encountering three heavy taxes and miscellaneous taxes, there are even bandits' mountain fees.

Zhang Shusheng paid attention to this group of bandits, and heard Sun Laixi say that these bandits were all from Yunwu Mountain, and their power was not small, and the local petty bureaucrats did not dare to care about it even if they closed their eyes.

The mountain road is difficult to walk, the road is treacherous, fortunately I spent some money to pass those checkpoints, and finally entered the city after walking slowly for half a day, if it were not for the discrediting of going out, the horror would have been afternoon by now.

Although the county seat of Huize is extremely dilapidated, it is worse than the most dilapidated county seat in Zhang Shusheng's memory, but at that time, Huize was the hometown of Tang Jirao, the governor of Yunnan, and he was somewhat taken care of, and the county was relatively prosperous, and even a small foreign bank had one.

He had no money on his body, so he ate some boiled potatoes to satisfy his hunger, and the first thing Zhang Shusheng did was to run to the pawnshop, ready to get some money to spend.

"Huh? Three fine pocket watches? "The boss who came to Qingdang heard that there were guests outside who wanted to be a pocket watch, and this thing was worth a lot of money, and it was not worth as much as gold and silver jewelry. But depending on where this kind of thing is produced, it is divided into the fineness of the process, expensive and cheap, so he personally walked out of the back hall.

"It's more accurate to go, and it's okay to look good." The boss is a businessman, and of course he talked about the three pocket watches with praise and disapproval. In fact, the heart has been happy, these three pocket watches are exquisite in terms of workmanship, even if they can't compare to the most exquisite gold and gem watches they have ever seen, but they are better than the fashionable style, the workmanship is especially good, it should be a new overseas product, and it can be sold at a good price.

Zhang Shusheng naturally understands the advantages and disadvantages of his things, there is a dream machine, and the watch has long been outdated, although it is not as exquisite as the most exquisite handmade watch, but it sells well, "Boss, you see that I am also a down-and-out scholar, let's make a price." Improper only selling. ”

"One counts you as 20 oceans, and three for a total of 50 oceans." The owner of this pawnshop is a ghost, seeing that Zhang Shusheng has an honest mud leg, but he doesn't look down on it, and as soon as he ruthlessly lowers the price, it will become this number.

As soon as the shopkeeper's hand was scattered, fifty oceans were placed on the pawnshop counter.

"5., 50 oceans...... "Sun Laixi has seen so many oceans, when he heard 50 oceans, his mouth couldn't close, he didn't expect that Brother Zhang was still a child of a rich family, and he could be such a valuable thing at will.

Zhang Shusheng secretly said in his heart that it was really a businessman, and he snatched back the watch that the shopkeeper was playing with with a quick grab, and turned his head to leave: "30 oceans, hum, let's go to another one!" ”

"Don't, don't...... Master, you have a price, and you always have to make a price for pawning things. "The boss was anxious, although these three watches were not inlaid with gold and silver, but the unique workmanship and fine appearance were sold for hundreds of oceans.

Zhang Shusheng waved the watch in his hand and said undoubtedly: "Sell two hundred alone, five hundred for three, and if you don't sell it, I'll go to the one in the west of the city." ”

"Five hundred oceans!!" The pawnshop owner and Sun Laixi both exclaimed in surprise, they didn't expect the three watches to be so valuable.

Zhang Shusheng knew it in his heart, and he didn't wait for him to bargain, and beckoned Sun Laixi to leave: "Let's go, let's go to the Baolaiju in the west of the city to try our luck, maybe there are people who buy it." ”

"Don't, don't. This master, don't go, I came to Qingtang to buy the things. "Maybe it was the name of Baolaiju that played a role, and the pawnshop owner gritted his teeth and actually agreed.

The transaction went smoothly, without any accidents, just five hundred oceans, although the amount is not particularly large, but it is very inconvenient to bring. But fortunately, the pawnshop owner was very surprised that he couldn't take out so much of the ocean.

"Little yellow croaker?"

Zhang Shusheng finally got 10 small yellow croakers and 200 current oceans, and the small yellow croakers shook so that he and Sun Laixi were both a little stunned.

After leaving the pawnshop, Zhang Shusheng was very careful all the way, keeping an eye on his back from time to time, and deliberately turned around a few times to find that he was fine, before pointing to an inn in front of him and saying, "Let's go and settle down first." ”

At this time, it was only 1915, the world was not in chaos, and Huize was Tang Jirao's old nest, and the public security was not bad, in the afternoon, Zhang Shusheng hid behind the window and watched for a long time, and after making sure that no one was following and monitoring, he took gold bars and silver dollars out. As for Laixi, throw him 30 silver dollars and ask him to buy some meat and cloth, as well as some miscellaneous things that the school needs.
