Su Yao thought for a while. If it was just for poisoning, he really didn't need to buy that medicine.

But if those were not poisons, what would they be?

"Lanling, shall we go in and ask the shopkeeper of the drugstore? He must know what medicine Qian Yougui bought."

Lanling nodded and agreed to his suggestion, "OK, now it's the only way."

When Su Yao and Lan Ling went in, the drugstore manager was sorting out the herbs and didn't notice them at all.

Su Yao pretended to cough a few times, "cough."

Hearing the sound, the drugstore manager quickly turned around with a smile on his face, "my two guests, what do you want to buy?"

"Shopkeeper, we have something to ask you about." Said Su Yao.

On hearing this, the smile on the face of the drugstore manager faded a little, "what's the matter?"

"What kind of medicine did that man take with you just now?" Su Yao said as he took out a ingot of silver. "Of course, I won't let the shopkeeper answer this question in vain. As long as you are willing to say, this ingot of silver is yours."

Looking at the silver ingot, the shopkeeper's eyes suddenly brightened, "I said, I said that just now the man came to catch the tocolysis drug."

Su Yao, who didn't expect to be the answer, frowned. "Are you sure he's only here to catch tocolysis?"

The drugstore manager thought carefully, "by the way, he also bought some arsenic, which he said was used to poison the mice in the house. I didn't think much about it, so I sold it to him."

Su Yao sneered in his heart.

Is it true that poisonous mice are false and harmful to talents?

I didn't expect that the money was so vicious that he didn't have to be polite to him.

Lanling didn't expect that Qian Yougui bought arsenic.

A small amount of arsenic can be used to cure diseases, but a large amount of arsenic can kill people.

The answer to whom Qian Yougui wants to harm with arsenic is obvious

Seeing that Su Yao and Lan Ling's expressions were not quite right, the drugstore manager couldn't help being a little flustered. "My two guests, what's the problem?"

"Nothing." Su Yao's mouth pulled out a smile, "thank you for telling us this, this Ding silver is your."

The shopkeeper of the medicine shop took the silver, and his smile on his face became more and more brilliant. "My two guests, would you like to have a look at the medicinal materials I have here, which are all top-notch."

Su Yao didn't pay attention to him. All he was thinking about now was something, "Lanling, let's go."

"Well." Lanling nodded and went out of the drugstore with him.

"Now that you know what medicine Qian Yougui is after, what are you going to do?"

"Of course, it's a tit for tat. Let Qian Yougui taste the evil fruit he planted." Su Yao sneered, his eyes full of cold.

Passing girl carefully looked at him and Lanling, the next second scared to the line of sight back, and then left here in a hurry.

These two childe seem to have a pair of good leather bags, but how can they look so terrible?

Su Yao and Lan Ling didn't notice it. They were thinking about the same thing.

"How do you think money will harm us?" Lan Ling asked.

"It's probably arsenic in our well water." Su Yao replied, "what do you think?"

"I think he's going to hurt us in this way." Lanling said, "and maybe he will burn a fire for us when he hurt us with arsenic, so as to achieve the purpose of destroying the dead."
