For Nunnally, life recently has been like a dream.

Especially after she signed the contract with the Northland Chamber of Commerce, the huge amount of gold coins made Nanali quite flustered. She even wondered more than once whether she was dreaming.

As a poor alchemist, Nunnally's biggest dream is to be able to do all kinds of alchemy research without restrictions. Instead of considering what is cheap and easy to buy every time she does an experiment, she even thought about using wild herbs to replace some alchemy formulas, just because it doesn't cost money...

Of course, these all exploded in the end. But this is also natural. If wild grass can replace alchemical materials, then alchemists will not burn so much money.

But now, Nanali doesn't have to worry about these problems.

Her alchemy workshop has signed a contract with the Northland Chamber of Commerce, and the technologies of the greenhouse and slime fertilizer are exclusively authorized for use by the Northland Chamber of Commerce. Not only that, due to the value of these two technologies, Nanali has been promoted two levels and become a third-level alchemist.

Not only can she obtain the alchemical materials she wants from the Alchemist Association, but she can also obtain some precious and rare alchemical materials from the Northland Chamber of Commerce. Moreover, Mr. Fress of the Northland Chamber of Commerce also promised to sell these materials at cost price, which is naturally a big surprise for Nanali. It can be said that Nanali has now completely lived the wonderful life she hoped for. She only needs to conduct alchemical research and experiments peacefully every day without worrying about starving to death or wandering the streets...

Of course, she also did not forget who brought all this upon herself.

“Knock, knock.”

"Come in."

Hearing the knock on the door, Nanali shook the bottle of medicine in her hand, and after confirming that the solution inside had calmed down, she spoke. After hearing her response, the door that had been closed opened, and then Fang Zheng walked in.

"How's it going, Miss Nunnally?"

"Ah, Mr. Ezio!"

Seeing Fang Zheng come in, Nanali also showed a happy smile on her face, but soon she sighed listlessly.

"I'm sorry, there's no progress yet..."

"The materials are difficult to match?"

"Well... it's mainly because there are some raw materials that cannot be replaced, and those that are configured always have various problems."

As she spoke, Nunnally looked at the side not far away. There were several wooden rectangular containers similar to flower pots, with a solution similar to fresh water at the bottom and a layer of perforated wooden boards on top, and some crops planted at the same time. However, the growth of these vegetables was not good. They were either listless, wilted, or dried up.

“It will take a long time.”

Nanali was also helpless when she said this, and Fang Zheng nodded. To be honest, he still thought things were too simple. At first, Fang Zheng thought that as long as there was slime fertilizer, it would not be difficult to prepare the nutrient solution for soilless cultivation. But when it came to the actual experiment, Fang Zheng found that it was not the case at all.

Indeed, slime fertilizer is comparable to Jinkela, which can accelerate the maturity of crops and make them grow better and better, but it is only a supplementary product after all. It is like a health product, which may make you strong and prolong your life, but it still cannot replace staple foods such as rice, noodles and steamed buns. You still have to eat and drink water.

Slime fertilizer can replace some of the nutrients to a certain extent, but it cannot completely replace the soil. Although Nymph has provided a list through the analysis of the earth's nutrient solution in the Iron Blood World, it is difficult for Nanali to combine all the elements on this list.

Not to mention, agricultural research is a very time-consuming job. You can't know whether a nutrient solution is usable by just taking a sip. You have to plant crops and wait for them to grow, mature, and bear fruit. You can only proceed to the next step after you are sure that everything is fine.

Fortunately, the slime fertilizer greatly shortened the growth cycle of crops, otherwise Nanali would have to waste even more time.

Now Nanali has cultivated more than a dozen kinds of nutrient solutions, but none of them seem to be usable.

"Is the preparation of the nutrient solution more difficult than expected?"

Fang Zheng said this casually, then reached out and picked up the experimental record next to him and began to read it. Nanali nodded helplessly.

"Yes, I have tried many combinations of herbs, but the results are not satisfactory. Some are good, but the price of the materials is relatively high..."

Since she used slime to extract fertilizer and build a greenhouse, Nanali has abandoned her original "only use the best" approach and started to develop in the direction of "only focusing on the cheapest". Her own alchemy skills and knowledge are very solid, but Fang Zheng has now discovered that this girl is very easy to get stuck in a dead end...

"Don't consider the cost factor for now."

Looking at the girl in front of him, Fang Zheng was helpless. Before, when he had no money, she didn't consider the cost at all. Now that she has too much money to spend, she has started to consider the cost instead.

"The price of nutrient solution is definitely higher than that of slime fertilizer, so don't think about reducing costs yet. In short, use all the raw materials you have to make nutrient solution that meets your needs, and then consider reducing costs. At the beginning, we didn't plan to sell our nutrient solution to farmers, and ordinary farmers probably can't afford it."

“Not selling it to farmers?”

Hearing this, Nanali was stunned for a moment.

“Who do we sell it to then?”

"The Holy Kingdom is a very good partner."

Fang Zheng seemed very confident. After all, he was a Knight Templar and had a certain understanding of the Holy Kingdom's philosophy and style. Even if the nutrient solution was made, the initial cost would not be greatly reduced. But if it was purchased by the Holy Kingdom, it would be different. For them, money was never a problem.

And if it is used to maintain order and fight chaos, then it will not be a problem at all.

Like the mercenaries who followed Fang Zheng to the Dark City, although they suffered heavy losses, they received a lot of rewards and compensation from the Temple after returning. According to Shi Dong, the compensation that mercenary group received was enough to equip half of a fully armed elite cavalry regiment.

The temple is wealthy and will never waste any money that can be spent on this.

After he became rich, Fang Zheng also hired someone to repair and renovate the entire alchemy workshop. Now the alchemy workshop is not as shabby as before, and it looks much better.

Basically, up to now, Nanali's alchemy workshop no longer serves as a "store", but has been transformed into a professional research institute. She no longer needs to accept other people's commissions to make things to sell for money, and she only needs to consider how to spend money to study alchemy. As for those greenhouses, Fang Zheng still kept them. After all, Nanali's research is in agriculture, and these things can still be used when large-scale experiments are needed. And the crops planted in them don't need to be sold after they bloom and bear fruit. They were sold before to increase the popularity of their products. Now that the Northern Chamber of Commerce has taken over these, the rest will naturally be given to the farmers in the greenhouses and the staff sent by the Alchemy Chamber of Commerce as welfare.

As for whether they took it home to eat or sell it, Fang Zheng had no control over it.

The important thing is that after the Northern Chamber of Commerce took the "patent" authorization for the greenhouse and slime fertilizer, the troubles that had been circling around disappeared. The Northern Chamber of Commerce got the exclusive authorization, and other forces had to deal with them if they wanted to get this technology again. As a researcher, Nanali was naturally excluded.

Of course, the Northern Chamber of Commerce also reciprocated by sending a team of people to guard the alchemy workshop. From this point of view, Fress is still very visionary and knows how to protect his "research assets". Others might be a little dissatisfied, but Nanali herself is a homebody who doesn't go out if she can, so she doesn't care.

However, this time Fang Zheng came to see Nanali not just to discuss the issue of nutrient solution.

"I will be away for a while in a few days. If there is anything next, I will leave it to you to handle."

"Why?"

Hearing Fang Zheng's words, Nanali was stunned for a moment.

"Mr. Ezio, are you leaving?"

"I have some personal business to attend to."

It was not a long or short time for Fang Zheng to deal with all these things. A month was about to pass. Although he had a very leisurely month, it was not in vain. You should know that this krypton gold summoning also took a month. After this month, a different card pool will be UP next month.

Fang Zheng didn't know what card pool would be updated next month. After all, this was not a game anymore, so he planned to take a trip to another dimension before the month was over - preferably a magic world, so that he could draw a magic soul stone. For Fang Zheng, this would be perfect.

“But, but…”

Hearing that Fang Zheng was leaving, Nanali was obviously reluctant to let him go. She was lonely living alone, and the arrival of Fang Zheng and Nymph made her feel the long-lost atmosphere of family. Although Fang Zheng's intentions were mysterious, Nanali didn't think he was a bad person. Moreover, he helped her do so many things... This made Nanali rely on Fang Zheng invisibly, but now Fang Zheng said he wanted to leave temporarily...

"Don't worry."

Looking at Nanali's uneasy expression, Fang Zheng smiled slightly.

"I'm just going on a long trip. It won't take too long."
