Reincarnation into the Barrier Master

May, Sidhi, and Serloitte returned to the laboratory with dozens of ferrari rats they had caught from Yannoli's fields.

After some investigation, they found that different species of ferirat reacted differently to friendly flowers. In some cases, some species showed no interest in the flowers at all. The three went to the garden of the Duke Fantastic's residence in the Grand Duchy of Foal every day, collected friendly flowers, brought them to the laboratory, and kept feeding them to the ferirats.

The rats to be experimented on were gathered one after another in the capital from all over Agartha, partly because Linos had offered a bounty on them. Originally, these creatures were exterminated by farmers for destroying crops in their fields. They were offered a bounty for their capture. For the farmers, it was a two birds with one stone story, and for this reason, rats were caught by many hands, mostly children, who were happy to earn money.

Ferry rats were sent to the laboratory one after another. The three women gave friendly flowers to the large number of rats.

After three days of experimentation from early morning to late at night, forgetting about sleep and food, the three women were able to determine which species of rats showed some interest in the friendly flowers.

"...... So you mean that male rats that are very close to old age are more likely to eat those flowers?"

Linos looked over the reports submitted by the three women and muttered to no one in particular. May nodded her head slowly.

On the contrary, the young males showed little interest in the flowers. And to tell you the truth, the females were not at all interested in the flowers.

"Why is it that only old male rats show interest in those flowers?"

"It's ......."

May glances at Serloitte. In response, Serloitte stepped forward.

"Whoa, perhaps it's the scent of flowers ......."

"Scent of flowers?"

Rats have an excellent sense of smell. But, sir, these friendly flowers are too fragrant. So, wow, the young males are ......."

"I see. So the scent is too strong and they're not interested.

"However, once the old gerbils start eating the flowers, they completely devour them down to their roots. That is why we think the spread of the flowers will be suppressed.

Sidi nods widely and opens his mouth.

"Or eat up to the roots. ....... Must be pretty tasty."

I'm sure they are.

"It's like durian."

"Dorian?"

"...... don't know. No, there is such a food. Do you have it here? ....... No, we don't. I've never seen it. I didn't know there was a food called durian. It has a terrible smell, but when you eat it, it tastes surprisingly good. Something like that."

"Hmmm."

Sadie's forefinger is resting on her forehead as she furrows her brow in an unmovable crease. This is the pose she takes when she is trying to remember something. If it is something she does not know at all, she closes her eyes and looks up to the heavens. She remembers eating the kind of food Linos describes when she was at her parents' house in Niza. She was trying to remember it.

"Say, ...... the meat of a big boar?"

"Well, that one has a smell. ....... I think it's safe to assume it's something like that."

"Hmmm."

Sadie looks as if she understands or does not understand. Linos decides that dragging this out is going to confuse her even more, so he turns his attention to May.

"So, I heard that when the ferry rats eat them, the flowers coagulate white. ......"

"Yes. We have found the cause of that as well.

May nodded broadly. As if on cue, Serloitte handed Linos and May a booklet that had been prepared in advance.

"It would take too long to explain everything, so I will summarize: Ferry rat saliva contains 8% Reisalt and 4% Caltrol. On the other hand, friendly flowers contain 64% of leisurth, which is the base of the fragrance. Is that ...... so far okay?"

At May's words, Linos nodded, a little puzzled.

"......Good. Now, I will continue the explanation. The saliva of the ferry rat is reacting with the liens in the flower of friendship and coagulating.

"I see."

"Generally, it is said that the ratio of Leithart, Kaltol, and Liens components must be 4:4:2 for a lean reaction to occur, but with this friendly flower, the reaction occurs even without that ratio. We have found that This is very surprising, and we do not know the cause of this phenomenon. However, we will pursue this issue as a subject for future research. As far as I know, the Lean reaction has not been studied in depth for about 80 years. This reaction ratio was also done using the equipment of the time. ......"

"Mei, Mei. ...... Um, Mei?　Can I have a word, please?"

"Oh, yes. I'm sorry. I spoke a little too much.

"No, no, it's okay. So, I'm going to coagulate that flower. ...... What?"

While Linos was talking, Serloitte put another document in front of him. Linos takes it and looks through it, puzzled. It contained a difficult mathematical formula that he could not understand at all.

"Um, ...... what is this?"

"Ha, I calculated the ...... possibility of coagulation of flowers."

"Uh ...... consequently, what percentage of this happens?"

"If the roots are completely eaten up, it's 100 percent."

"Hundred percent?"

Serloitte nodded slowly.

"It's just a calculated probability, but I think it's probably right. My intuition tells me so."

"If Sidney says so, I guess he can't be wrong. Just go to ......."

Linos folds his arms and looks in the wrong direction.

"The problem is stability. It's going to be hard to find rats that have the condition to make flowers wither, and it's going to take time to raise such rats, too. Oh, that's it. Once they start eating flowers, they eat up to the roots, right?　That means that the sense of smell of rats is ...... oooh!"

Suddenly, a piece of paper was held out in front of Linos. He looked up and saw Serloitte holding the document.

"Let's see ...... what's this?"

"Squeak, it's a way to reduce the sense of smell."

"...... indeed, you are very meticulous."

Linos takes the paper offered to him and reads it over, half in disgust. There was something more than he could understand.

"Well, I mean, ......."

"In other words, Oxalite can be used to reduce the sense of smell in rats."

"Oxalite?"

"Rigalil and Phalacite, Colenchytarra, and Lysolarel ...... each diluted twice ......."

"Mae, Mae. It's okay. Yeah, it's okay. So we got it, right?"

"Yes. But as the master pointed out, it is not stable. It varies from one individual to another.

"In other words. If you reduce the ferry rat's sense of smell, the rats will eat the friendly flowers. If they eat the roots, the flower will almost certainly die. Now we are trying to find the most effective way to reduce the rats' sense of smell so that they will eat the flowers. Is that what you mean?"

That's right.

"Yes, I understand. I appreciate you elaborating on that. ....... From now on, just the conclusion. I don't know what's so hard for ...... rats, but I don't know what's so hard for me.

"Pfft ...... ahahahahaha."

May laughs at Linos's words. Sidi, on the other hand, gives Linos a tense look. Behind her, Serloitte gently offers May a handkerchief. .......
