Back at the meeting point, Ye Chen gathered them again.

"Very good, in the future, you will be the soldiers of the Ye family's guard battalion, your responsibility is to protect the Ye family, have you heard clearly?"

"Yes".

After suffering a loss, they are all smarter, at least this time it is much more neat.

Ye Chen talked about the rules of the guard camp again, and then said: "Have you seen this land, this is your training ground, and now I will give you a task, which is to level this land for me, and build a barracks for me to live for 500 people in the middle of the mountain, and there must be toilets, and enough toilets must be built."

This piece of land is at least two and a half football fields the size, and it is more than enough to train 500 soldiers, even if you can barely accommodate 3,000 people.

As for Ye Chen's special explanation that it is necessary to build a toilet, it is not difficult to understand, many people in this era do not pay attention to hygiene, which can easily lead to diseases, so it is particularly emphasized.

After explaining the task, Ye Chen went back, and when he went back, he asked people to send enough simple tents, and the barracks had not yet been set up, so he could only live in tents first.

In the past few days, Ye Chen didn't plan to train much, because the school field had not been cleaned up, and the barracks had not been cleaned up, but the morning training and the ten kilometers in the morning and evening were still thunderous.

On the way back, Ye Chen saw patches of farmland, and suddenly found that the way to increase the harvest was not only to cultivate more fields, but also to provide yield per mu.

Although it is not clear about the current yield per mu, it certainly cannot be compared with the yield per mu of 800 catties or even 1,000 catties in later generations.

Ye Chen then wanted to know more about it.

"Old man, how much grain can be harvested in one acre of this field."

Ye Chen asked the old farmer who was plowing the field with a hoe.

Although the old farmer didn't know who Ye Chen was, he should be a rich man dressed in it, and Ye Chen had a good attitude and no malice, so he replied to Ye Chen.

"In a good year, the production capacity per mu is three quintals." The old man said as he waved his hoe.

The yield per mu is 6 quintals, which is equivalent to only 280 catties per mu, and an adult man consumes 600 catties of grain a year. In ancient times, peasants had to pay taxes and land rent for more than half of their harvest, that is, one person had to plough five acres to have enough to eat.

Therefore, in ancient times, farmers were very bitter, and a family often did not have enough to eat on ten acres of land, and it was common for them to starve to death.

Ye Chen secretly estimated, not to mention the current yield of 800 catties per mu, even if it can be increased by dozens of catties, then more than 100,000 mu is a huge increase.

The best way to increase income is to cultivate grain seeds, but Ye Chen doesn't understand, and he doesn't have that condition, the only way is to use fertilizer.

Of course, fertilizer is not phosphorus fertilizer and nitrogen fertilizer, but only compost.

Composting is very simple, adding animal manure to dead branches and fallen weeds, etc., piling it up at high temperature, letting it ferment, and drying it after fermentation, so that it becomes fertilizer.

"Old man, do you use fertilizer when farming?" Ye Chen asked with a smile on the side.

"Yes, yes, when the crops are planted, there will be some dung splashed at the time." The old man looked tired, and wiped his sweat with a hoe.

It seems that at this time, farmers have discovered the role of fertilizer, but they do not understand the use, the correct way to use fertilizer is to put fertilizer first, then put the seeds on top of the fertilizer, and then cover the soil.

The fertilizer should be in full contact with the roots of the crop to be effective. This is put when it is planted, and this is called basal fertilizer.

The fertilizer that needs to be used twice later, generally called top dressing, is usually just sprinkled on the farmland at this time, and the effect is not as good as the first time.

Ye Chen learned some more about the old farmer and went home.

Back in Ye Mansion, Ye Chen asked Dong Xue to call Manager Wu.

Manager Wu didn't dare to delay, after all, Ye Chen showed extraordinary ability, and he was relatively strong, although he was pedantic, he was not stupid, knowing that Old Man Ye had already delegated power, he didn't have to ask what Ye Chen could do.

"Manager Wu, you go to each Zhuangzi to find two young laborers to come over, and everyone who comes will be assigned a ploughing ox to their homes, and in addition, the salary will be calculated according to the daily standard of the Ye Family Restaurant."

Because of the use of the curved plow, the Ye family has hundreds of more ploughing cattle to distribute.

"Young master, what are you going to do here? It's not that I'm talkative, it's been the busiest time for spring ploughing recently, you..."Steward Wu was hesitant, the meaning was obvious, and he asked Ye Chen to wait for spring ploughing before doing it.

Ye Chen was dissatisfied, this Chief Manager Wu didn't even ask me what to do, and began to deny it, is there such a subordinate? If he had been the boss before, he would have been fired a long time ago.

Ye Chen was not familiar with the dozen or so farms below, and he had to rely on Manager Wu to do things, so he just explained: "Manager Wu is very important in this matter, it is related to the harvest of the farmland, I am looking for someone to make fertilizer, and it must be completed before spring sowing, otherwise the effect will be very different."

When Mr. Wu heard this, he immediately became anxious, and said to Ye Chen with a trembling voice: "Young family master, how much effect can this fertilizer play?" In previous years, it was not that it had not been tried, it really didn't play a role, and now the spring ploughing can't be completed, there are more than a dozen Zhuangzi below, two people in each Zhuangzi, that is, more than 20 strong laborers."

Although Mr. Wu is bitter, it has the opposite effect, and the fertilizer has no effect? Something that has been proven in later generations.

"Manager Wu, are you the young master of the Ye family or am I the young master of the Ye family." Ye Chen couldn't help but be angry, fertilizer manufacturing is urgent, how can it be delayed.

"Young master, you are the young master". Manager Wu was taken aback, and his words were trembling.

"Okay, immediately order to go down and let each Zhuangzi send two people."

Manager Wu didn't dare to object, walked out, and when he arrived at the door, Manager Wu muttered: "The young master is really a loser, it is their duty to let them work, and it is just a matter of giving priority to the distribution of ploughing cattle, and they also take care of the food, pay back the wages, and pay so much for the wages."

Mr. Wu shook his head as he spoke. If Ye Chen heard it, he would probably kick people in anger, but Ye Chen already had a strong desire to replace Manager Wu.

Towards the evening, people finally came, a total of 26 people, all of whom were young and strong in the village. They were not dissatisfied when they came here, because the allocation of one ploughing ox was worth five of them, not to mention the wages for working here, and it was said that they were still full of food.

Ye Chen gathered them together, asked the kitchen to fry a few dishes, and entertained them first.

The Ye family's stir-fried vegetables are famous in the city, and they can only eat them if they are rich and expensive, but they didn't expect Ye Chen to come to entertain them with a group of mud legs.

A group of people ate so much that they almost swallowed their tongues.

"Young master, we are all full, let us tell us if we have anything."

"Yes, young master, you can go up the knife mountain and down the sea of fire."

"I, I, I have only one strength left in addition to farming."

A group of men are loyal and righteous people, and whoever is good to them can die for whomever they want.

A ploughing cow can feed their family, not to mention that Ye Chen is so good to them that he actually gives them all the delicious food.

"Haha, thank you very much, in fact, it's very simple to call you here, I have invented a new method of making fertilizer, which can increase the yield of farmland, at least 20 catties per mu."

Ye Chen's words made a group of men stunned, more than 20 catties per acre, then a family cultivating 10 acres would be 200 catties more, so that they would not have to go hungry.

Ye Chen's words The people present were all excited, what is the biggest, the biggest meal, as long as they can let them eat enough, they will follow whomever they want.

"Young master, you called us here to let us make fertilizer, I think this spring ploughing is about to be completed, and the next thing is spring sowing, or we will start to put it immediately, so that we can make more fertilizer."

A slightly literate young man stood up, his clothes were very torn, a little ill-fitting, and they were all patches, but his resolute face was full of energy.

Ye Chen was very happy, how simple the peasants of this era were, just begging for a full meal.

"It's a little late today, but from tomorrow we have to work from morning to night, and we have to continue to work with torches at night, because time is running out, and spring sowing is about to begin, but everyone can rest assured, four meals a day are full."

Many people couldn't help licking their mouths and swallowing their saliva when they heard Ye Chen's words, the food here is so delicious, usually two meals a day, and they are half full, but now they can eat deliciously, and they are full.

Everyone patted their chests and said that there was no problem, and they would definitely complete the task assigned by Ye Chen. Then Ye Chen asked them to go and get the tools first, and since the Ye Mansion was not far from their Zhuangzi, there was no need to arrange accommodation.

Early the next morning, Ye Chen went to the barracks again, and only a small piece of the school field was sorted out, and the barracks were still preparing materials.

Ye Chen lectured first, instilled some words that were loyal to the Ye family and loyal to himself, and then ran ten kilometers, and then Ye Chen went back.

Yesterday, the group of men all arrived early, and waited for Ye Chen after eating, and when they saw Ye Chen coming over covered in sweat, they all greeted him warmly.

Ye Chen took them to a clearing next to the farmland and began to teach them how to make fertilizer.

The first is to dig a pit, dig a big pit, and after digging it is compost, pile up animal manure, dead branches and leaves, etc., and pour water, to reach 60% water.

In this way, high temperature will be automatically generated, microbial fermentation, and after fermentation, it can be dried in the sun, and the result is a very high fertilizer biofertilizer.

The technique is simple, and Ye Chen will understand them after teaching them for a while. To Ye Chen's surprise, the man who didn't fit his clothes yesterday actually had strong organizational skills.

Soon after I started working, I automatically entered the command role, coordinated the division of labor of the whole team, and the speed was much faster.

Ye Chen learned that this person's name is Li Qing, a native of Lijiazhuang, age 27, because his parents died early, he lives alone with his younger brother who is ten years younger, so he is relatively poor and is still single.

Ye Chen arranged things for him, let him take charge, and then went back.

Ye Chen still has a lot to do.
