In ancient times, a county had a population of more than 100,000 households, that is, there were 500 villages with 200 households, and the land of a county was at least 5 million mu, and the number of chickens and ducks needed to eat up one acre of locusts Zhang San did not know.

But during the locust plague, the number of locusts in the land is huge, and if you want to eat up an acre of land, you need at least 100 chickens or ducks, right? Five million acres of land will require at least 500 million. What is this concept?

Suppose there are ten counties affected by the disaster, and you have 100 million chickens and ducks, then it will take 50 days to eat them all, and after 50 days, you will have to come a second time, and 100 million chickens and ducks are enough for one person in the entire Song Dynasty.

Therefore, if you want to solve the locust plague with chickens and ducks, it is almost impossible in Zhang San's plane, unless you know that a locust plague is about to occur in a certain place, and you can prepare three years in advance, and then it will be possible.

But Zhang San obviously doesn't have that ability, now that the locust plague has risen, Zhang San can do very little, but Zhang San knows that locusts are good things, high-protein food, even if people don't eat it, it's still good to make feed for chickens, ducks and pigs.

Zhang San decided to mobilize a batch of grain to Tokyo, and exchanged grain for locusts, so he exchanged one pound of grain for five catties of dried locusts, and then harvested a large amount of fodder, and solved the livelihood problem of some of the people.

Moreover, catching locusts can be done by women and children, without strong labor, and these dried locusts obtained by Zhang San can be ground into powder to make feed, which can expand the scale of his farm, and raising more chickens, ducks and pigs can also increase the supply of meat for his subordinates.

Thinking of this, Zhang San immediately wrote a letter to the Weiyuan Dart Bureau, asking Hangzhou to start purchasing grain and shipping it to Tokyo. And the money to buy grain Zhang San plans to hand over to the Weiyuan Dart Bureau in batches to transport, one or two thousand at a time, and now the Weiyuan Dart Bureau can make a trip from Tokyo to Hangzhou every five days, so that it is enough to transport 120,000 yuan a month to Jiangnan.

In this way, there is no need to send a master to escort every time, and the longer this route runs, the mountain bandits and water thieves in the passing places will also be in place, and the safer the route, the safer the money and grain will be transported.

There are at least fifty people in a dart boat dart master plus a dart ding, and two dart boats at a time are a hundred people, and after the old bandits are all tied, those who are new to the industry are not to be afraid, because the new entrants are generally small bandits, more than a dozen people, and dozens of people are rare, so Zhang San can directly transport money to Jiangnan from Weiyuan Dart Bureau in the future.

After Zhang San arranged the grain transportation, he immediately asked Li Si to be responsible for setting up a special feed workshop, and expanding the area of the current chicken and duck farm and pig farm, preparing to buy more of these animals to fill in.

In the afternoon, Zhang San was in class, Carpenter Zhao came to Zhang San, since he was appointed as the head of trust research, he worked harder than his younger brother, Zhang San looked at the wooden box he handed over, the box contained the badge made according to Zhang San's requirements.

Zhang San held the badge in his hand, and felt that these craftsmen had really worked hard, and they were very delicate, the eight-pointed star was very plump, and the pins on the back were also very strong, Zhang San thought about it and said: "On this back, the name of the person and the badge number should be engraved." Can this be done? ”

Carpenter Zhao nodded and said, "No problem." ”

Zhang San nodded: "Well, that's good, I'll provide you with a list later, and then you will be engraved by name." Now you need to make a hundred Black Iron Badges. ”

After Carpenter Zhao left, Zhang San thought about it, this matter has always been handed over to Shuang'er to do, and I don't know how it is doing? Zhang San thought about walking towards Shuang'er, asked the teacher who was passing by, and said that he saw Shuang'er in the office, and it seemed that two children were fighting very badly, and Shuang'er was dealing with it.

Zhang San frowned, there were children fighting, Zhang San walked to Shuang'er's office, came to the door and looked inside, Zhang San was a little stunned for a moment, there are still acquaintances here.

I saw Shuang'er sitting on the stool, staring at the two children standing angrily, the two children standing, one is Zhang San's younger brother Lu Bu, and the other is Zhang San's apprentice Gao Chong, and Leng Qingqiu is crying on the side.

The two children seemed to be a little unconvinced by each other, gritting their teeth, Zhang San coughed and walked in, the two children looked at Zhang San, and immediately lowered their heads in fright, Lu Bu naturally needless to say that he has always respected and feared Zhang San.

Gao Pet didn't feel much afraid of Zhang San before, he only felt that Zhang San was more powerful, and he wanted to learn things from him, but as he stayed in school for a long time, everyone mentioned Zhang San with respect and worship, which made Gao Pet who stayed in it gradually become in awe of Zhang San.

Zhang San sat down next to Shuang'er, and when Shuang'er saw Zhang San coming, he was also relieved, and said, "You are here, come and see these two, one is your younger brother and the other is your apprentice, you can discipline yourself." ”

Zhang San looked at the two of them and said, "Leng Qingqiu, come and tell me what's going on?" ”

Leng Qingqiu looked at Zhang San and said, "Brother, I'm playing chess with Brother Lu Bu, and Brother Gao is going to play too." It's just that Brother Lu Bu didn't let him, and Brother Gao said that Lu Bu of the Three Kingdoms was a 'slave with three surnames', and then the two fought. ”

Zhang San was also shocked when he heard this, and asked, "Do you two have anything else to add?" ”

The two children didn't speak, they looked at each other, they didn't speak, Zhang San looked at the two children who were about ten years old, and sighed, this is not a heavy word, I am afraid that it will have no effect if it is light.

Zhang San thought about it and said: "You should also have heard what Teacher Wu Shuang said, I was going to select a hundred outstanding students in the school, who will have the eight virtues of filial piety, humility, integrity, mercy, bravery, justice, sacrifice, and honor. When the time comes, they will be given the title of chivalry. I didn't expect the two of you I liked the most to do such a thing. ”

Where is Lu Bu's humility, if you can't tolerate a word from others, you will become a selfish, small-bellied person in the future, do you know?

And your high favor, your compassion? What about your humility? What was Lu Bu's intention when you met Lu Bu in front of the Three Kingdoms? Do you want to be a villain who relies on insinuations and rumors to slander other people's reputations?

Zhang San looked at the two of them and bowed their heads without speaking, sighed and said: "One of you is my younger brother, the other is my apprentice, you must set an example for others in your words and deeds in the school, and when I am not there, you have to help the teachers maintain the order in the school, what are the virtues of chivalry that you tell me now?" ”

The two children immediately recited: "Filial piety, humility, integrity, mercy, valor, justice, sacrifice, honor."

Respect for teachers and friendship, strong enemies at present, fearless, courageous and benevolent, worthy of teaching, loyal and upright, rather than give in, protect the weak, and do not violate the principles of heaven!

I swear to respect the teacher.

I swear to help my brother.

I swear to be sincere with my friends.

I swear not to bully the weak.

I swear to stand bravely against power.

I swear to fight all mistakes.

I swear to fight for justice.

I swear to help anyone who comes to me for help.

I swear to be kind to all the weak.

I swear that I will die for what I love. ”
