The Frontier Alchemist ~ I Can't Go Back to That Job After You Made My Budget Zero

"Are you sure about that, Rust?" Kalin looked surprised.

While everyone was looking at the monster I had taken out with astonished expressions on their faces, Kalene was the first one to ask me a question.

"Yes, I have confirmed it. The water containing the poison from the tentacles of this monster is the cause of the endemic disease.

"Yes, we use river water, but the water bottles have a water purification function. Even if it is used, it should be able to purify the monster's poison ......" said a skeptical Karin.

"Yes, the water in the bottle is well purified and there is no problem," I confirm Karin's doubts.

"Then why in the world?

"The problem is not the purified drinking water, but the water that was used without purification for domestic use."

"What!　Could it be ......?" said Karin. Her gaze fell on the two people gathered here. One was the woman in charge of serving the meals in the tent. The other was the manager of a tent for singles.

"That's right. It seems that water from the river was used directly for washing dishes and clothes. In fact, the dishes and the washed clothes showed trace amounts of the catfish poison. The trace amount of poison must have accumulated in the body through the mouth and skin, causing the endemic disease," I show him the scroll of the "transcription.

"Ah, so that's why there were so many single patients..." muttered Ary.

"I am very sorry, Ms. Kalin..." "I take full responsibility for this..." the two responsible begin to apologize.

"No, the amount of water purified in the water bottles is limited, so the ration is fixed. It was I who decided on a flat ration by dividing the ration by the head. It is not the fault of the two of us. I will review the rations for each facility," said Kalin.

"So, Master Rust, not only did you treat the patient overnight, but the next day you found out the cause of the problem, killed the monster, and eliminated the cause of the problem," said Karin. Her face was a mixture of amazement and dismay.

Roa mutters "too much of an outlier is sarcasm".

I chuckled at the sound of Roa's muttering.

"No, actually, I happened to have killed one on my way here. And it was Hippopo that we defeated. So it's just a coincidence that the problem was solved so quickly.

"By the way, it was only yesterday that we defeated it. I think it would be better not to use the river water as it is for a while yet. I have asked you two to discard the river water for washing. Well, the source is already gone, so we should be able to use it in a few days. Hippopo, there were no other monsters in the pond, right?" And I .

Hippopo shakes his head, "Bumo bumo! She's so proud of herself, which is cute.

I look at him, straighten my posture, and turn to Kalene.

"Kalin-sama, I am pleased to report that the treatment and elimination of the cause of the endemic disease you ordered me to do has been completed.

Kalin's face tightened up and she responded with the face of a statesman.

"Master Rust, your work this time was truly wonderful. You have exceeded our expectations and far exceeded our expectations. I thank you."

I then drop my formal posture and ask normally.

"It seems that the poison was caused by the accumulation of a small amount of the poison, so there is still a possibility that some people will develop the disease in the future. Please inform everyone that we will continue to treat any changes in their health condition.

"Okay. I'll let them know.

"And if you have an extra water bottle with a water purification system, I'll make one if you give me a budget," I ask her.

"Budget, huh? Okay," Karin promised with a wry smile.
