Of course, Fang Zheng couldn't really take the vampire on a date. There were so many things to deal with in the entire Tiandao Palace, and with the arrival of the royal fleet, he had even more things to do.

For example...

"Ah, Mr. Founder!"

Seeing Fang Zheng coming in, Nanali waved to him happily. Fang Zheng nodded at her and then looked around.

"What's the situation? Are there any results from the research on the nutrient solution?"

“It’s almost successful!”

Nanali was quite excited when she heard Fang Zheng's question. After entering Tiandao Palace, she did almost nothing but focus on studying the nutrient solution for soilless cultivation. Kulia was mainly her assistant and also served as Nanali's external contact window. If it weren't for this childhood sweetheart, Nanali would probably stay in the laboratory for a month without going out.

But one has to admit that this reclusive alchemist really looks a bit like a great scientist. At least... her current "appearance" is very similar to the pictures of scientists that Fang Zheng has seen in various history textbooks.

"Ah...! Nunnally, why did you get yourself into this again!?"

At this time, Kulia, who was yawning, also came out of the bedroom. When she saw Nanali with a messy hair, the girl screamed immediately.

"You are too casual in front of Master Fang Zheng. Ah, there are guests. Go take a shower quickly and smell what you smell like!"

"Eh? But... I still need to explain to Mr. Fang Zheng..."

"No buts! How can you, a young girl, face others in such a state? Go take a shower quickly. I will take care of Master Fang Zheng!"

As she spoke, Kulia pushed the dissatisfied Nanali into the bathroom, then slammed the door shut. The girl let out a long breath, turned around, walked to Fang Zheng, and bowed to him respectfully.

"I'm sorry, Master Fang Zheng, I made you laugh..."

"nothing."

Fang Zheng certainly wouldn't take such a small matter to heart. He also knew Nanali's personality, so he didn't care much about it. On the contrary, Fang Zheng was quite interested in what the alchemist had said before.

"By the way, she said the experiment is almost finished?"

"Oh, yes, please follow me."

As expected of someone who used to work as a receptionist in the Alchemist Association, Kuliya was very clear in her introduction. She brought Fang Zheng, the vampire, and Tina to the experimental table next to her. There were already several wooden boxes for soilless cultivation experiments, with numbers written on them. From the planting conditions, it was clear at a glance.

"Nunali prepared fifteen groups of nutrient solutions before, but after screening, only five groups met the conditions for another experiment... Lord Fang Zheng, what you are seeing now are the last three groups left... It can be said that each has its pros and cons."

"oh?"

Hearing this, Fang Zheng immediately became interested.

"What do you mean?"

"The first group is the best performing so far. It can be said that it has fully met the standards you required, Master Fang Zheng. The crops are growing very fast, and there are no abnormalities after the fruits mature. However, the nutrient solution formula requires a high level of sophistication, and some relatively expensive raw materials are needed... In short, it requires a regular alchemist to prepare it, and ordinary apprentices cannot complete the preparation work. As for the second group... although the preparation requirements are not high and the cost is relatively low, the temperature requirements are very strict. If it is in an extremely cold or hot climate, it is likely to fail. The third group can achieve the perfect effect, but one of the raw materials is difficult to find..."

"Well... this is indeed a problem, but it is not our problem."

Fang Zheng certainly understood what Kulia said. The fertilizer they sold to the Northland Chamber of Commerce before was made of simple and convenient raw materials, and it was easy to manufacture. Even an alchemy apprentice could make it. That's why it could be mass-produced. However, this kind of nutrient solution required a regular alchemist to prepare it, which was a bit too difficult. After all, the number of regular alchemists was very limited, and it was impossible for them all to do this kind of work.

But for Fang Zheng this is not a problem. As he said, the nutrient solution is mainly sold to the Holy Kingdom to change the current situation. If the Holy Kingdom can see the huge value contained in it, it will naturally make great efforts to improve and develop it.

For Fang Zheng, this thing is mainly a stepping stone to bring himself and the Holy Kingdom closer... Of course, mutual benefit is still very important.

“Are all the crops grown edible?”

"No problem. Miss Nymph has also checked it. According to her, the crops grown using these nutrient solutions seem to have higher nutritional value than those grown simply from the soil."

"Bring out the three sets of cost comparison tables for me to see."

"OK."

Kulia was obviously well prepared. When she heard Fang Zheng's order, she immediately took out a notebook from the side. Fang Zheng took it and quickly flipped through it. Well, fortunately, this time Nanali didn't use anything like "Black Dragon Blood" to make the raw material formula, but...

"What is this purple unknown substance?"

Fang Zheng pointed at the strange name in the notebook. Based on his observations, this thing seemed to be an important part of the third set of nutrient solution. Nanali had written down where to find the other ingredients, but only this thing...

"this……"

"That's what you're talking about, Mr. Fang Zheng."

Hearing this, Kulia's face looked a little strange, and at this moment, Nanali came out of the bathroom - at this moment, the alchemist had washed himself thoroughly and finally looked like a human being.

"I was just about to ask you where you got this thing from."

"Ask me?"

Faced with Nanali's sudden question, Fang Zheng was also stunned.

"Ask me what?"

"It's like this. I accidentally found that purple thing near the southern portal when I was taking a walk outside. I thought it was a mushroom or something, but after testing it, I found that it is very suitable for making a nutrient solution formula! But... I don't know where to find this thing..."

"What purple mushroom?"

Faced with Nanali's gesticulating description, Fang Zheng was completely confused, and Nanali hurriedly took a box from the laboratory table next to her and opened it.

“That’s it!”

"This is……"

Fang Zheng curiously leaned over to take a look, and after seeing the true appearance of the "purple mushroom", he was completely speechless.

What the hell... isn't this a fungal blanket?

I'm afraid this might have been dropped accidentally by a Zerg when it went through the portal.

Thinking of this, Fang Zheng couldn't help but look at the girl in front of him with a weird look.

You actually used the Zerg's fungal blanket as raw material for nutrient solution?
