Fang Zheng originally thought that as long as he negotiated the deal and asked Nanali to buy the spirit crystals, he could sit at home and spend money happily. But...

"That's all?"

Looking at the less than ten spirit crystals in front of him, Fang Zheng's face darkened.

"I'm so sorry..."

Seeing Fang Zheng's expression, Nanali hurriedly apologized to him.

"I went to the Alchemist Association and found out that there is a quota for purchasing spirit crystals. I am only a junior alchemist, so I can only get this much every month..."

“…”

What use are these broken spirit crystals? Fang Zheng might have gained more from hunting monsters in the snowy forest. Moreover, the quality of these spirit crystals is not very good. A rough calculation shows that they can only increase the crystal energy by a few dozen points...

"Even if I have money?"

Fang Zheng has never seen a person who has money but cannot make the devil work, but judging from Nanali's expression, it seems that this is really not possible.

"Oh well……"

Fang Zheng could only accept this result helplessly.

"So, how can we get a large amount of spirit crystals?"

"This... at least requires me to upgrade to a level 5 alchemist..."

From Nanali's words, Fang Zheng finally understood the upgrade system of the Alchemist Association. In the Alchemist Association, there are two ways to upgrade. One is simple manufacturing. The alchemy workshop manufactures a specified standard and quantity of potions a year, and then the association purchases them. Then, you get points, and when you reach a certain amount, you can upgrade your level.

The other is creation. The alchemist's job is to research and invent. If an alchemist can create a brand new invention that has great market and application value, then he can be upgraded after being evaluated by the Alchemist Association. Not only that, if his invention is used and manufactured by many alchemists, then the points will be further increased.

"This is troublesome..."

After hearing Nanali's answer, Fang Zheng was speechless for a moment. He originally thought that he could do whatever he wanted with money after getting the qualification, but now it seems that the other party has obviously had similar experience and has blocked the loopholes tightly. It is impossible to rely solely on buying and selling, so what should I do? There is no other way, just farm and level up.

Simply relying on the Alchemist Association's commissions would definitely not work. Not to mention that this alchemy workshop is poor and has few equipment. Even if there was, Fang Zheng thought about it carefully. It would take a year or two for a girl like Nanali to upgrade her level.

Then all that was left was to create a new invention, send it to the Alchemist Guild for evaluation, and then upgrade its level as quickly as possible.

But... this is not easy.

"A secret recipe passed down from generation to generation?"

Staring blankly at Fang Zheng, Nanali's face revealed a hint of surprise.

"I'm sorry, there is no secret recipe in my family. My mother is just an ordinary alchemist..."

That's true. If this young lady had some secret recipe passed down from her ancestors, she wouldn't have ended up like this. Fang Zheng originally thought she was destined to be the protagonist, but now it seems she's just a passing heroine.

"So, we can only invent things ourselves? That's not easy..."

Fang Zheng frowned as he flipped through the catalog of the Alchemist Association. These alchemists were crazy about inventing things. They had invented all kinds of potions, weapons, transportation, power reactors, and other things. In Fang Zheng's words, everywhere you looked, there were patent barriers everywhere. It was impossible to even make a copycat or reverse engineer it... Hmm? Wait!

After flipping through the "Patent Encyclopedia" in his hand, Fang Zheng's eyes suddenly lit up. Then he quickly opened the catalog and flipped through it again. Then, Fang Zheng discovered something.

Although on the surface, the inventions of these alchemists seem to cover everything under the sun, there is one area that they have hardly touched upon!

agriculture!

In the entire Alchemist catalog, Fang Zheng found only two inventions related to agriculture, one with an effect similar to that of chemical fertilizers, and the other with an effect similar to that of pesticides. To his surprise, when he asked Nanali about them, she proudly told him that both were invented by her mother!

Is there anything wrong?

Fang Zheng was shocked to hear Nanali's answer. These are pesticides and fertilizers, and they are unique in the world. I don't believe you will become the richest man in the world if you make them! How could you get to this point? Are you kidding me?

Looking at Fang Zheng's expression, Nanali was obviously a little embarrassed. Then she explained it, and only then did Fang Zheng understand the reason.

Although the environment in this world is similar to that on Earth, it is much better than on Earth. The soil is extremely fertile, and crops can grow very well without special fertilizer. As for pests and diseases... In the main world, there is a small monster that specializes in eating pests. All farmers raise them. Like cattle, they are necessities, so the market for pesticides is not big.

What’s more important is that although the two inventions of Nanali’s mother are quite effective, they are too expensive!

Nanali's mother may have obsessive-compulsive disorder, so she completed these two inventions to perfection, and the materials used were also very high-end. Although the fertilizers and pesticides made from these materials have various benefits and are pollution-free, the problem is that they are expensive! If farmers buy them back and use them, their annual income is not enough to cover the cost, and they are completely losing money!

"Why……"

After listening to Nanali's story, Fang Zheng also frowned, not knowing what to do for a moment. Although he had the Iron Blood World in his hands and could take out a bunch of high-tech products from there, Fang Zheng knew very well that the main world was not the fantasy world with a medieval civilization level like in many novels. Moreover, when he was at the Sky Arena, he also got to know a lot about the "intellectuals" in this world. If he wanted to fool them, he might as well fool the natives of the Middle Ages.

If a completely new system product that is completely different from the current system is launched, it would be strange if no one doubts it.

According to Nanali, the pesticides and fertilizers that time travelers can use to show off have no market in this world. So, if you want to break through the "patent barriers" of those alchemists, you have to work hard on the hardware? But agricultural hardware is not something that can be made casually...

"Why……"

Fang Zheng sighed again. Why did he feel that instead of staying in this field, he might as well go to the border and kill monsters? It was just a waste of time. Besides, it was freezing cold, and he had to bring a tent... Hmm?

Thinking of this, Fang Zheng's eyes suddenly lit up.

Yes, how could I forget this!

Ordinary agricultural machinery is not easy to deal with, but isn’t greenhouse a good direction?

"Nunali."

"Yes, Master Ezio, what do you want?"

Hearing Fang Zheng's voice, Nanali also sat up straight in a hurry and asked respectfully. She was not stupid. Fang Zheng asked so many questions just now. She also knew that the other party wanted to improve her alchemist level and obtain more spiritual crystal quotas. Now Nanali was also very nervous, because she and the young man named "Ezio" only had a verbal agreement. Now she was really afraid that the other party would think that the value was not enough and turn around and leave. If that happened, then she would definitely not be able to collect the fees to pay the Alchemist Association. At that time, her mother's workshop would be...

“What do the farmers here do every winter?”

"winter?"

Nanali obviously didn't expect Fang Zheng to ask her such a strange question, but she thought about it and answered it anyway.

"In winter... everyone has nothing to do. Some people go hunting in the mountains together, and most people stay at home and wait for the spring of next year..."

“If they were asked to farm in winter, would these people be willing to do so?”

“Can we farm in winter?”

Hearing this, Nanali opened her mouth in surprise. After a while, she reacted and nodded vigorously.

"Of course. After all, there is nothing else to do in winter. Besides, hunting in the mountains is very dangerous. Many people are actually unwilling to do it. It's just because there is really nothing to do, and... there must be some gains."

No matter which world, the peasant class is the most miserable group of people. The main world is of course much better than the serfs in the Middle Ages. Since the soil in this world is fertile, planting crops is more effective than using chemical fertilizers, so there is no need to worry about reduced production and famine, and the food grown is enough for the people of a country. But even so, the income of farmers in the main world is still very small. According to Nanali, many of them venture into the mountains to hunt in winter just to get more mountain products to sell and make some money.

If there really is something good that can be used to grow crops in winter, these farmers would definitely be more than happy to have it!

but……

“Can we make something like this?”

Nanali obviously had no confidence in this. Changing the climate was something that even legendary wizards found difficult to do, and she was just an alchemist!

"Of course, and it's easy."

In response to Nanali's question, Fang Zheng said he felt no pressure at all.

A greenhouse is such a simple thing. There is a pile of information on Earth in the Iron-Blooded World. You can just copy it and then use alchemy to create a version for another world. What difficulty is there?

only……

Looking at the girl in front of him, Fang Zheng sighed helplessly.

Others started out in the other world with high technology, but I started out in the other world just to farm?

For a Zerg Overlord who controls millions of Zerg and is already engaged in an interstellar war, isn't this a bit too low-brow?
