I'd been told of this very different shop down in China town. So being that I had a plan for some very close relative's demise I went to the shop.
The proprietor met me right off and asked for what reason I came to look. I was not going to lie to the man and informed him I wanted something to bring great trouble on a man. If possible I wanted him to know who had do it and just how terrible my justice was going to be like.
The man offered me some strange ideas, from making the man seen dragons by night or actually become like unto an animal. I was a little put off by his suggestions and he saw this in my facial expressions.
A trial he offered and it was for me to give one of the potions to another. I then could watch and learn how potent his potions were and see the effects first hand.
He searched about and then came up with one in a mason jar. His explanation of how it worked seemed to me as too simple and likely to fail.
I took it home and set the jar on the kitchen counter never giving a thought of its rank possibilities. It was during dinner that the wife told me of how she had basted the meat in that interesting jar of soy sauce I'd left on the counter.
I jumped up and called the shop asking for the proprietor as I had a question. His nice young niece told he was out for to get their dinner and would return within the hour.
Then as I returned to the dining room table and sat down ready to explain my intentions to the wife it was easy to see how the potion was beginning to react on her and soon, me.
