It is not difficult to build a greenhouse with the level of alchemy in the other world, but the problem is that something is needed to replace the plastic film. Fang originally placed his hopes on Nanali, but soon he found that he had made a mistake.

"Deep sea monster... Dragon Wing... Underground spider mother..."

Looking at the list in front of him, Fang Zheng was speechless.

"Ms. Nanali, I remember that I made my request very clear. What we need is a transparent film that can be used to keep heat and moisture, and to keep warm... Are you... planning to make some kind of artifact?"

Even Fang Zheng knew that most of the creatures on this list were legendary creatures. Let’s not talk about whether they could get them. Even if they did... what was the use of these things?

"But, but, according to what you said, sir, I think these are the best!"

"But it's not enough!"

Fang Zheng reluctantly put down the list in his hand, stretched out his hand, and gestured to the brown-haired girl in front of him.

"Let's take the dragon wings for example. Even if we succeed in slaying the dragon, how much area can a dragon wing converted into a thin film cover? More importantly, this is not a one-time deal! This is a long-term business! We may have to sell thousands or even more in the future. By then, where can we find another dragon? Not to mention the price. The price of these things... I won't talk about how much time and money it will take to slay the dragon. Even if we get it back, the dragon skin is not something that can be made casually!"

Fang Zheng originally thought that the reason why the girl's business had not been making progress was because of bad luck, but after actually starting to work, he discovered that Nanali and her mother had the same problem. No matter what invention they made, they would immediately think of the best materials and then pay no attention to other issues...but the problem was that those precious materials could not be mass-produced at all!

Besides, I'm just building a greenhouse. Why does your list give me the feeling that you're planning to colonize Mars?

"terribly sorry……"

After hearing Fang Zheng's reply, Nanali finally understood what her problem was, and immediately took back the list dejectedly. Fang Zheng also sighed, and then looked at the little angel beside him.

"Nymph, do you have any good suggestions?"

"So how about this, Master?"

Nymph, who was looking up the "Encyclopedia of Magic", heard Fang Zheng's question, blinked, and then turned the book over. Looking at the information on it, Fang Zheng and Nanali were both stunned.

"...Slime?"

"Is this low-level monster really useful?"

Nanali's first reaction was suspicion. It was because monsters like slimes were too low-level and could almost be considered the lowest link in the entire main world's food chain. Most of them lived in dark forests and caves. These slimes themselves were not strong and posed limited threats. In addition, they were of little use, so even mercenaries were not interested in hunting them.

But for Founder, this is not a problem.

"It feeds on mosses and decaying matter. Its skin is soft and elastic... It is difficult for ordinary blades to injure it... It only lives in places with dense vegetation..."

Looking at the introduction of slime in the encyclopedia, Fang Zheng thought for a while.

"Anyway, go check it out."

It was easy to find slimes. In fact, they could be seen in the caves around the town. There were many slimes, but they were not very dangerous. They were not aggressive and moved slowly, so ordinary villagers would not go out of their way to find them. Therefore, it didn't take much effort for Fang Zheng and the others to find the "legendary" slimes.

“That’s it.”

Looking at the slime in front of him, Fang Zheng frowned slightly. The slimes in the main world were very different from the cute little monsters in the game in Fang Zheng's memory. They looked more like a pool of squirming mud. These slimes ate everything, but they moved slowly, so it was obviously unrealistic for them to hunt animals and humans. So the slimes mostly devoured plants and rotten corpses. In addition, they were not animals and had no fur, so they were covered with a layer of mud all over their bodies, which made them look even worse.

But this does not mean that slimes are harmless like little white rabbits, because when they are attacked, they will release a venom to paralyze the opponent's nerves, making it paralyzed, and then slowly swallow it into the body for digestion. The process is somewhat similar to feeding with pythons or spiders, but the venom of slimes itself is not very toxic, and at most it is only effective against rabbits and the like.

This was certainly not a problem for Fang Zheng. In fact, even the weak little angel could handle it easily. Only an alchemist like Nanali who was powerless could not do anything about it.

“Crash!”

Fang Zheng waved his hand casually, and soon a water ball appeared out of thin air, and then hit the slime, washing away all the mud on its body. After washing away the mud covering the slime's body, Fang Zheng finally saw their true form clearly - these slimes looked a bit like translucent jellyfish, but without tentacles, and looked like a squirming ball of water.

Slimes don't have organs like eyes, and the encyclopedia didn't say how this creature senses its surroundings. But Fang Zheng didn't care. He went up and stabbed the slime with his sword. Then he saw the slime's originally swollen body suddenly tremble, and then immediately paralyzed.

The life core of the slime is a small ball in its body. As long as you stab that thing, the slime will be killed in one blow.

"Nymph, come and see what these things are for."

"Yes, Master."

Hearing Fang Zheng's words, Nymph squatted down, stretched out her hand and placed it on the slime's body. Then, the little guy's eyes began to emit a bright light.

"... scan the biological surface... analyze the core... conduct further analysis..."

After a moment, Nymph blinked, stood up, looked at Fang Zheng again, and smiled happily.

"Master, it's done!"

"Looks like the results are good?"

Seeing the little angel's cheerful look, Fang Zheng also raised his eyebrows. Nymph was still very respectful in front of him. If the little angel was not sure about the things she was assigned to do, she would never show it so obviously.

"Yes."

Sure enough, upon hearing Fang Zheng's question, the little angel nodded happily.

"According to the results of the inspection and analysis, these slimes meet your requirements. Their skin is very suitable for replacing plastic film. Not only that, I also found that the internal organs of these slimes have high nutritional value and can be used as fertilizer."

"oh?"

Hearing this, Fang Zheng immediately became interested. He never expected to receive such an unexpected surprise!

Fertilizer is certainly a good thing. No one would complain that they grow too much food. The fact that the fertilizer submitted by Nanali's mother passed the assessment of the Alchemist Association is enough to prove the problem. However, Nanali's mother made the same mistake as scientific researchers, which is that she doesn't care about costs... If the cost cannot be reduced, then there is naturally nothing to say.

But slime is different!

These monsters are easy to kill, there are a lot of them, and they are even easy to breed... Well, after learning about the function of slime from Nymph, Fang Zheng has decided to set up a slime farm when he returns.

But before that, he still needs to do one very important thing.

"I'll leave it to you from now on, Miss Nunnally."

What Fang Zheng needs to improve is Nanali's alchemist level. If he merely gives the role of these slimes to the Alchemist Association, they will only be a supply of raw materials. Only after these things have been processed by alchemy can they be considered real alchemy products.

Although Fang Zheng was somewhat interested in alchemy, he and Nymph knew little about it, so now... they could only rely on Nanali.
