[Ellie's P.O.V.]
"Alright." Kirk thought for a while and finally agreed.
We took the account book and left the place. Then, we went to the hospital and found the doctor from before. We handed him the kettle and explained that the inner wall might contain substance X. The doctor's eyes lit up as if he was very interested and immediately took it for testing.
As usual, Kirk and I waited outside for the results. This time, it should take a long time for the test to be completed because the water in the kettle had dried up. Moreover, after being exposed to nature for a few days, it had become a little rusty.
However, the results came out surprisingly fast. In less than two hours, the doctor came out with a smile on his face. I could tell that it was a success. Kirk and I quickly went to him. The doctor said, "You guys are right. There is substance X on it and it's formed by a direct mixture of the calming pill and the water from Arya River."
