The reason why it is placed on the third floor, rather than the first floor, is that the price of these things is higher than that of the first floor, but it is not very useful.

Su Caiyin glanced at it and was about to leave, but at this moment, there was a sudden hot pain in her left palm.

This feeling is like a stinging pain, and it is like the pain of fire, and it is like this suddenly, Su Caiyin was completely unprepared, his whole hand twitched, and a low cry came out of his mouth.

"Ah......h

"Miss Su, what's wrong with you?" The shopkeeper was startled, Su Caiyin was still fine a moment ago, but who knew that suddenly his face was pale and trembling, as if he was injured.

But there was no one on the third floor except for a few of them, so it was impossible for her to be attacked, and she didn't look like she was injured.

"Ah, miss, what's wrong?"

"Miss!"

Stone and Xiaorou heard her exclamation and ran over one after another.

"No, it's okay...... It's just that my hand is cramping. Su Caiyin pulled out a smile.

"Oh, I see."

"That, shopkeeper, what's this black bump?" There was a strange light flashing in Su Caiyin's eyes, and his gaze was fixed on a stone-like thing.

It was almost at the last corner, and Su Caiyin naturally couldn't look down on it, but she could feel a consciousness in her body that didn't belong to her surging out, shouting with great longing-

To it, to it!

"That thing ......" the shopkeeper's face was a little strange, "cough, it seems to be the poison sac of some kind of demon beast, but its poison is a little violent, as long as you touch it, it can be corroded immediately." ”

The face seemed to be a little disgusted and a little afraid.

Poison sacs? Su Caiyin seemed to understand something.

Her hands were clasped together, using her normal right hand to counteract the hot heat of her left palm, I don't know if she knew that Su Caiyin understood what she meant, and her left palm finally began to normalize.

"What's the price of that thing?" She asked, frowning.

The poison sac should be more toxic inside, but this thing will be corroded just by touching it with your hand, which shows how toxic it is.

Su Caiyin really didn't want to touch such a poisonous thing, but ......

Who let her have a tree ancestor in her body, and torture her if she disagrees.

"Miss Su, do you want to buy it?" The shopkeeper was stunned.

"Miss, that thing is poisonous, you can't buy it!" The stone panicked.

"Uh-huh!" Xiao Rou, who had always listened to Su Caiyin's words, also rarely objected, and nodded in agreement with Shishi's words.

"I've got my own measure." Su Caiyin glanced at them.

"This thing...... Five hundred taels. The shopkeeper saw that Su Caiyin really had this intention, so he touched his nose and replied.

"What? Shopkeeper, you still need five hundred taels for this broken thing, you can't rob money! The stone was furious, stretched out his huge fist and clenched it, and suddenly there was a scalp-tingling creaking.

"Hmph, Miss is willing to buy because she can afford you, you dare to blackmail us!"

Xiao Rou raised the newly arrived sledgehammer and shook it threateningly in front of the shopkeeper.

Xiaorou is very angry, and the consequences are serious!

"No, no, it's not my random asking price, this is already the reserve price, because this thing is at least the poison sac of a fourth-order demon beast! If it weren't for the fact that ordinary people can't use it, it's worth even more! "The shopkeeper wants to cry without tears.

"What about the fourth order, haven't you been here for so long? My young lady is willing to ask for it, but you still don't give a real price! Xiao Rou slapped the table violently.
