"3 tons of struvite...... According to the average dosage of 30 catties per mu, the actual cultivated land area must be more than 100 mu, which is much larger than expected. ”

On the way back, Chu Guang was thinking while writing in a small notebook with a pen.

"It seems that my speculation is correct, they should have applied a part of the soilless cultivation technology, and this part of the production capacity accounts for 15%~30% of the total production capacity...... And even more. ”

Brown Farm would make some of the manure itself and buy a little from other merchants, and the actual area of arable land would be larger than he thought.

Before the crossing, Chu Guang had heard of a pipe-type soilless cultivation technology, which can maximize the use of space and water resources, as long as the fertility is sufficient, one acre of land can be used as ten acres of land.

In the pre-war era of this world, there seems to be a similar technology, and the use of space to the extreme, regardless of energy costs, the development of automatic sowing, cultivation, ripening, harvesting, assembly line transportation, packaging and distribution integration of the "skyscraper", can really achieve more than 10,000 catties per mu.

It is called the numerical control planting tower, which is the ultimate body of industrial planting technology.

Very cyberpunk.

The energy of Brown Farm is certainly not so luxurious, but since it can exchange some electricity for food, it should not be too scarce.

In addition, they have been planting fields for a century, to say the least, and will inherit some of the technology and improve it to adapt to the wasteland environment.

At this time, Chu Guang suddenly had a whim.

"Could it be...... Planted some kind of energy crop? ”

Brown Farm doesn't just grow barley, it's said it ripens quickly, and after the harvest there is a chance to plant a round of croissants, beans, fruits and vegetables, or other crops.

Maybe it's the latter that has the greatest demand for fertility?

Ethanol and biodiesel have been produced from cash crops, by-products or specially cultivated crops since the end of the 20th century, and as the technology matures, these crops are sometimes classified as "energy crops" depending on their use.

It is reasonable to assume that in the pre-war world, where controlled fusion technology has been mastered, similar technology may be more advanced than he imagined.

However, in the era of major breakthroughs in nuclear fusion technology, the practical use of this energy crop should not be to produce a substitute for fossil fuels.

Rather, it is used as an industrial raw material.

“…… Brown Farm itself does not have industrial capacity, and produces some kind of economic (energy) crop, which is partly used as fuel and partly sold to merchants from Boulder City as industrial raw materials for the factories in Boulder. ”

"The product is suspected to be some kind of rubber, crude oil analogue or other hydrocarbon."

"Moreover, the consumption of fertility by this crop should not be small!"

Chu Guang wrote this line in his notebook.

The harvest of this transaction is even greater than he imagined.

Not only the grain and tools in the caravan, and the "order" for 3 tons of struvite at the beginning of next spring, but also the intelligence gathered indirectly through the transaction.

In particular, this information was impossible to collect when he was still a scavenger.

When you go back, you can make it public on the official website for players' reference.

Just as Chu Guang was analyzing this information, the players next to him were also beeping quietly.

"1 kilogram of struvite can be exchanged for 10 kilograms of grain? I'm not mistaken. ”

"You read that wrong, it's 12 kilograms."

"I don't understand whether this barley is too cheap, or the stones we picked up from the lake are too valuable."

"Maybe both? Maybe neither...... Wait, how much is the grain we buy from the warehouse? ”

"What 1 kilogram of green wheat and 1 silver coin looks like, I know what you want to say, you can only exchange 1 kilogram of struvite stone and move it back to the warehouse for 2 copper coins, right?"

"That's right! Is this reasonable? ”

"Don't worry, although there is no farming system now, I bet that the price of NPC barley will definitely not exceed 1 kilogram and 1 copper at that time, is it reasonable to think about it?"

"Poof, it's a river in the Tay River...... What a hammer! Sell us 1 silver coin 1 kilogram! ”

"Calmly, what game isn't like that? Besides, if you have to be more realistic, isn't the price of food also fluctuating up and down in reality? At that time, some players will be sold, and those that can't be sold will be sold to the NPC's granary. ”

Speaking of this, the player whose ID is [Canyon Fugitive Mole] sighed and said with a regretful expression.

"It would be nice if the runner system could be opened, 1 kilogram of struvite stone will be transported to Brown Farm for grain, and 12 kilograms of grain will be transported back, even if it is sold to NPCs, it will be more than 2 copper coins! 12 kilograms, to say less, there is 1 silver believe it or not? It's a scary game to think about. ”

Although Chu Guang didn't look up and ignored him, he still glanced at this guy and smiled in his heart.

That's right.

But the pattern is still small.

If you take struvite stones to Brown Farm to exchange for grain, and then take the wholesale grain to Boulder City to exchange for guns, believe it or not that a hundred kilograms of guano can be exchanged for five or six guns?

Feel relieved.

When the spring of the next year begins, your great manager will do this business for you, and the chips you earn will be the foreign exchange reserves of the base, and they will be divided into you.

What?

Do you want to settle your rewards in Boulder currency?

What, you still want to buy a house and marry a wife in Boulder City?

In fact, Chu Guang didn't mean to "exploit" his little players, and compared to the farmer of Brown Farm and the old leech on Bate Street, he was not exploiting at all.

In Chu Guang's blueprint, at the latest, the currency issued by Vault 404 will replace the chips issued by Boulder City and become the hardest currency in the entire Qingquan City and even the surrounding areas.

Suffering a little now is also for everyone to enjoy happiness together in the future.

"Administrator, there seems to be someone in front of you."

“？”

Still coming?

Xiao Ben stuffed it back into his pocket, and Chu Guang's right hand reflexively stretched out the sledgehammer behind his back, but as soon as he touched the handle of the hammer, he found that the so-called people were the same.

I saw that the strong man who had confronted him at the door before was holding a shotgun against the serf he had brought out earlier.

The latter knelt on the ground trembling with his head in his hands.

The group stopped.

Chu Guang looked at the strong man, and the strong man also looked at him in a daze.

"What's the matter?"

"Nope."

Chu Guang glanced at the poor man who was pointed at the gun and didn't dare to move, then looked at the strong man again, and asked with a strange expression.

"What is this?"

The strong man didn't want to explain, after all, this was his own private matter, but seeing that this group of people was not easy to provoke, he still said cautiously.

“…… He was a slave to his master, he was old, he had arthritis in his legs, he couldn't do any work, and he broke a plate yesterday. The host asked me to pull him outside to dispose of it. ”

After listening to the strong man's words, Chu Guang remembered that every winter, Brown Farm seemed to dispose of a few slaves who couldn't do heavy work and no one bought them, and then buy new ones from slave traders in the next year.

As for where did these slaves come from?

Hells know.

Some are auctioned off by creditors because of debts, some are lost their freedom by marauders, some are simply cloned products, or some forgotten vault facility is suddenly unsealed.

Chu Guang even heard that some scavengers sold themselves or their relatives because they couldn't survive.

In this wasteland, a slave who is nearing the end of his life is not even worth a two-headed ox that can carry goods.

At least the latter has more meat on it.

"Please, please let me live."

The strong man glanced impatiently at the man kneeling on the ground.

"Even if I let you go, where will you go? Let's give you a good time, don't embarrass me. ”

"Please, please......"

The serf could not say anything else.

"Wait a minute."

Chu Guang stepped forward and looked at the old man kneeling on the ground.

"How old are you?"

“51……”

It's a bit old indeed.

As far as slaves are concerned, it is already an advanced age.

But on the other hand, it also means experience.

Chu Guang continued to ask.

"What will you do?"

As if seeing the hope of life, the old man turned around tremblingly and reached out to hold the life-saving straw.

When the strong man saw this, he kicked him away with a quick kick and scolded.

"Don't touch your master's guests with your dirty hands, do you want to be hanged?"

His eyes could tell that the gang had business dealings with their masters.

Although he was kicked, the old serf didn't care at all, he didn't look at the strong man when he got up, and raised his wrinkled face to look at Chu Guang.

"I, I can farm, I can also read the numbers, I can do carpentry, and I can move things...... I can do anything. "Please, my lord, give me a way to live."

"You can also count," the strong man sneered, "and you can count those potatoes as well?" Don't listen to his nonsense, my lord, he can't do work anymore at his age. Two bands of slave traders came this month, and none of them were interested in him. ”

Chu Guang took out a white chip from his pocket and flicked it into the strong man's hand with his thumb.

"Is that enough?"

The strong man's expression was happy, and he nodded hurriedly.

"Enough is enough."

No matter how small the mosquito is, it is meat, and besides, this slave is not his

After putting away the chips, the strong man raised his shotgun and fired a shot at the sky, then picked up the bullet casings on the ground, bowed to Chu Guang, and happily carried the gun back to hand it over.

The serf shrank on the ground and trembled, obviously frightened by the shot just now, and looked like he had lost his soul.

Chu Guang instructed a player to step forward and pull him up, bring him to him, and looked at him in a commanding tone.

"I bought your life, and now you work for me."

Finally came back to his soul.

The serf immediately wanted to kneel, but was stopped by Chu Guang raising his hand.

"We don't kneel here, put your right fist on your left chest to show loyalty. If I find out any betrayal or infidelity on your part, don't let me do it, dig it up and feed it to the dogs. ”

This kind of scaring words Chu Guang means that if there is really a traitor, throw it into the active substance extractor and refine it, there is no need to go to such great lengths at all.

Although Chu Guang himself is a civilized person.

But having lived and observed here for a while, he knew that there were some problems that could not be solved by the minds of civilized people.

Aborigines and players are fundamentally two different creatures.

In the case of indigenous peoples, indigenous methods of management have to be used.

It's good for both parties.

"Yes, my lord," said the old man, bowing his head respectfully, his expression much more reassured, and sensibly pressed his right fist against his chest, "to offer you loyalty...... My name is Luca, no, I don't have a name, please give me a name. ”

"Let's call it Luca."

Chu Guang was too lazy to waste time and beckoned to the players.

"Keep going."

"We're going back by noon."

……

This trip to the business can be said to be full of harvest.

300 kg of struvite for 3,600 kg of barley and croissant, 100 kg of bacon for 500 kg of barley and 5 tools.

Although Chu Guang wanted to quibble, venison and hyena meat are different, the former will be rarer than the latter, after all, it is not always possible to encounter deer migration, but the other party said that since this is the case, let's take hyena meat, anyway, as long as it is not human flesh and rat meat and fish meat, etc., it is the same for them, Chu Guang has to give up.

However, on the other hand, Liu Zhengyue still looked at the relationship between the two parties and made a small concession, allowing him to choose 5 tools or 1 pound of tobacco leaves to take away, which is considered a gift.

Of course, Chu Guang chose tools, and he picked pipe wrenches and fire axes. Even if you don't need it at that time, you can bring it back to make steel and copper.

In addition, 25 kilograms of smoked fish were exchanged for almost 150 kilograms of scrap metal.

Unlike the aluminum and steel alloys that can be seen on the streets, these metals are good products containing copper and zinc.

Originally, Liu Zhengyue didn't want to sell it, but maybe she thought that the merchants wouldn't come for a few months anyway, and it was useless to stay on the farm, so after asking the owner, she nodded and agreed.

The midday sun shone overhead, and the shadows of the trees swayed on the road.

With the exception of one player with the power to pull the cart, the rest of the players are scattered around the caravan.

Occasionally, when they saw mutant cockroaches approaching, they would scream and rush up and beat them with sticks, which was even more exciting than the xenomorphs.

If the xenos could think, they would be stupid at this point.

Who exactly is the prey?

The only thing Chu Guang needed to do was to stop their hoarding habits, and they wanted to put anything strange in their pockets when they saw it.

Although the stomach of the mutant cockroach can occasionally turn out some indigestible gadgets, and the luck can even turn out chips or bullets, but the probability is too small.

Most of the time, it is cockroach eggs that are found.

Old Luca shivered as he watched from the sidelines, probably frightened by the actions of these people.

He had never seen such strange people, and he couldn't understand what they were thinking.

However, Lukka knew very well that as a servant, he didn't need to think about it, and the less he knew, the longer he lived, so he didn't say anything along the way, and his sense of presence was as if it didn't exist.

I want to sing in a happy mood.

Led the caravan back to the outpost, Chu Guang, who had just arrived at the gate, happened to see that the two brothers of the Yu family who were carrying their prey were anxiously gesturing with the players at the south gate.

Chu Guang's eyes lit up, and he called out from afar.

Hearing the familiar voice, the Yu brothers immediately turned around and waved their hands with joy in their eyes.

"Brother Chu!"
