The inner city under the moon was deserted, and there were hardly any people to be seen on the streets, except for the occasional patrolman passing by.

At Merlin's doorstep, Green is saying goodbye to Merlin.

"Green, do you really want to leave now?" Merlin glanced at the sky, "Why don't you rest for the night before leaving?" ”

"Oh~ man, you're not kidding, are you?" Green raised his left hand and showed the glass bottle he was holding in his left hand, "See this?" This is the lube that your mother gave me. And this. Green showed the metal syringe in his right hand, "This is the sausage device your father gave me." If I slept in your room for one night, our relationship really couldn't be explained! ”

"Don't pay much attention to what my parents say, they talk to themselves a lot. It's good to get used to it. Merlin looked calm, with a "I'm used to it" expression.

"Oh~ I don't want to get used to parents like this." Green paused and frowned slightly, "How does that sound weird...... We're not in that relationship, so they're not my parents, and I don't have to get used to them...... Oh! Damn it! Let's stop at this topic! Anyway, I'm leaving! I don't want to stay here at all! ”

"Okay." Merlin could understand Green's feelings, "Oh, by the way, about the taunt potion, is that okay?" ”

"Yes. I feel like I've got a clue. Green waved his hand, "I'll go back and study it, and I guess I'll get the results soon." ”

"Okay."

"Then let's say goodbye." Green said impatiently.

"Well, see you at school."

"See you at school."

Green left Merlin's house with the lube and sausage that Merlin's parents had given him.

Although some unexpected circumstances occurred, Green's operation this time was relatively smooth, not only successfully obtained the true recipe of the taunt potion, but also received two valuable "gifts" - Merlin's mother gave Green a bottle of lube, and told Green and Merlin to "ask her if you run out", and Merlin's father gave Green a magic guide to clean his ass.

Although these two gifts made Green feel chrysanthemum pain, he could not deny the value of these two gifts. In particular, if you sell the syringe-shaped magic guide, it can be sold for at least the same price as a few magic guide muskets.

With mixed feelings, Green returned to the academy.

The distance between the inner city and the academy was not too close, and by the time Green returned to the academy, it was already late, and most of the remaining students had already returned to their dormitories.

"Grimm, wait a minute." At the door of the dormitory, Miss Dorm Administrator stopped Green, "Someone is looking for you today." ”

"Looking for me?" Green stopped, "Who?" ”

"A knight. He left you a note. Miss Administrator handed the note to Green from the window.

"Okay, thanks."

Green took the note and looked at it. This note was left by the Berry Knight, who had escorted Grimm to the Wall. The knight came to the academy to inquire about the progress of the development of "herbicides", but it was clear that Green had no intention of researching herbicides.

"Are you going to visit tomorrow night?" Looking at the agreed time on the note, Green felt a little headache, "What a troublesome guy. ”

The arrival of the Berry Knight did not affect Green's plans.

Early the next morning, Green took his notebook and a few Chaos Mushrooms to the Herb Garden to Professor Anne to buy a batch of materials and a set of alchemy tools, and then went through a "dormitory check-in" procedure in the ordinary dormitory, and made an ordinary dormitory as a laboratory.

Green then plunged headlong into the lab, intending to conduct his own potion experiments and find the correct recipe for the "taunt potion".

The biggest difference between a "taunt potion" and a "radiant potion" is the ratio between the Chaos Mushroom spores and the Dream Mushroom spores. If you don't have Chaos Mushroom Spore, it will be a radiant potion, and if you add Chaos Mushroom Spore, it will turn into other potions.

Green has also been involved in the preparation of potions several times, and has a lot of experience, so the process of mixing the potions was relatively smooth, but the results were not very satisfactory - Green has not been able to find the correct ratio between the Chaos Mushroom spores and the Dream Mushroom spores, and instead has made many strange potions.

"Hmm...... It feels like I'm almost going to find the right recipe. Green put down the potion he had just prepared, rubbed his forehead, picked up his notebook, and wrote down the wrong recipe.

Looking at the many recipes in his notebook, Green mentally assessed the point of the problem.

It took a day for Green to make ten potion concoctions. Two of them failed completely, and the things that were refined could only make people have diarrhea, and the remaining eight bottles of potions all had a certain magical effect, but there was no "taunting potion" in them.

"The more spores there are in the Chaos mushroom, the more annoying it is; The more dream mushroom spores, the stronger the enchanting effect. And the effect of 'taunt' should be somewhere in between, which is disgusting and makes people want to get closer to ......."

Edison conducted more than a thousand experiments to find the best material for light bulbs. Green didn't know how many experiments he would have to experiment to find the right ratio between the two materials.

"The train of thought should be fine. I'll leave the rest to someone else. ”

If it is an ordinary person, in this case, you can only slowly experiment next to each other to find the most correct formula ratio, but Green, as a big lord, after determining the idea, the rest of the "repetitive work" can be completely handed over to others to do.

After sorting out the data, Green decided to return to the dormitory and leave the rest of the work to the territory's research department. Maester Harry, the head of the Demon Lord's research department, is a doctor who is well-versed in pharmacy, and this research work is in line with his specialty.

When Green returned to the dormitory, a handsome, tall knight was sitting in the hall on the first floor of the dormitory, drinking coffee. The knight drank his coffee, generally paying attention to the direction of the dormitory door.

Seeing Green appear, the knight quickly stood up.

"Oh~ Master Green, I've been waiting for you for a long time." With a warm smile, the knight walked over.

"Oh ~ Hello Knight Berry." Green had a somewhat stiff polite smile on his face, "Please wait a moment, I'll go back to the room and put something away." ”

"No problem." The knight was polite.

After saying goodbye to the knight, Green returned to his dormitory room, put his things down, and then took out a document from the drawer and went downstairs.

"I've been waiting." Green pulled out a chair and sat down.

"Nope." Knight Berry shook his head, "Master Green, do you have an eyebrow for your research on 'herbicides'?" ”

"Oh~ Your Excellency, I'm not interested in herbicides at all." "What I said was 'not ruled out that herbicides will be found during the study.'" ”

Hearing Green's words, Knight Berry frowned slightly: "That...... Your Excellency, do you have any recent research findings? ”

"Recently, I have a new research topic, so the plants outside the Great Wall are no longer my main research direction." Green handed the data in his hand to Knight Berry, "But I still found some interesting phenomena about those plants outside the Great Wall. ”

"What is this?"

"Magic and the effect of matter on plant development. Simply put, the more magic you have, the faster your plants will grow. Grim paused, "Well, I think you should know a little bit about this, so I won't explain it too much." But interestingly, different 'fertilizers' also have an impact on plants. Like flesh and blood. ”

"Flesh?" Berry frowned slightly.

"Yes, flesh." "If the fertilizer is mixed with blood and flesh, it will not only make the plant stronger, but it will also make the plant more aggressive. ”

"Hmm...... You're trying to say that if too many adventurers die while cleaning up the plants, it will make those plants outside the Wall even more aggressive? ”

"That's just one aspect. Since flesh can make plants more aggressive, is there anything that can make plants milder or outright inactive? Green knocked on the table and paused, "Of course, this is just a direction to think about. Personally, I don't have much interest in this research, but if you are interested in it, you can consider funding some researchers, or asking the Royal Society for help. ”

Hearing Green's words, Knight Berry took a closer look at the data and reports provided by Green, thinking about what Green said.

"Master Green, aren't you going to continue your research?" Knight Berry looked at Green.

"Oh~ If it's a study of how to make those plants more lethal and easier to control, I might be more interested." Green shrugged, "I'm really not interested in this kind of non-lethal research. ”

Hearing Green's words, Knight Berry seemed a little disappointed: "Hmm...... Master Green, can you give me a copy of this report? ”

"I only have this data in my possession, but you can copy one yourself and take it with you."

"Thank you very much."
