"Miss, where did you hear that? I only have gold, silver, and jewelry here. If you want some ancient items, I do have them. However, Grass Dragon Saliva is a medicinal ingredient. How could I have it?"

The thin and long haired owner only frowned as he looked at Duan Cheng Xuan. He didn't know why someone would wear such expensive clothes to the black market, but he wasn't afraid of being robbed.

Gu Daiyan, however, was not annoyed. He was just playing with the hairpin in his hand. The hairpin looked like it had been there for a long time, but it was well-preserved: "How much silver for this hairpin?"

"This is an ancient artifact from a hundred years ago. Young lady, you have good eyes. Twenty taels of gold is fine."

Duan Chengxuan naturally knew that this object wasn't worth 20 taels of gold, so before he even opened his mouth, Gu Daiyan had already stretched his body and pulled the boss's sleeves. The guards by the side all drew their sabers one by one and faced Gu Daiyan.

"Your identity card is not bad."

Gu Danyan reached down and only took off the thing on his waist, then held it in his hand to play with it.

However, I fed you some poison when I was grabbing your shirt. If you don't want to die, just call the person over to your head over. If you talk properly, I can afford to pay for the grass dragon saliva.

The people beside him drew their sabers in unison. The people who came to buy looked at Gu Daiyan, but they didn't know where he had gotten such a terrifying poisonous woman.

The owner's face was ashen, and he was almost unable to breathe. He only instructed the workers beside him to hurry up and call for someone.

Gu Danyan only had a cold expression on her face. She ignored Duan Chengxuan as he walked to her side and continued to hold the hairpin in her hand. She only threw the hairpin back when she walked down with a big belly.

Duan Chengxuan didn't know that she was so formidable, so Cheng Shan hurriedly followed behind his with large and small bags.

If it were the potbellied boss, this matter would have been easy to deal with.

The moment Duan Cheng Xuan entered the room, her entire body's aura burst forth, and by her side, Cheng Shan's face was full of seriousness as well. Only Gu Liuyan glanced at the Grass Dragon's Saliva in the box, nodded seriously, and carried the items out of the room.

"Madam …" Cheng Shan was slightly surprised.

The boss didn't say a word and even made a gesture of 'please'.

After the few of them left the dark shop, Gu Xianyan patted the box in her hands in satisfaction. Duan Cheng Xuan pulled her over and said, "It's only been a few days since you left, yet you've already gone on a rampage."

"I just heard from the person just now that if I did such a thing, I would be ambushed in the night. If I kill them back then, I wouldn't have to pay money." Gu Danyan only smiled lightly and found an inn to stay at together with Duan Chengxuan.

The two of them shared a room in the name of husband and wife. Duan Chengxuan only wiped his blade. "I only see you saving people."

"Those who resell goods on the black market deserve to die, I don't need to pity them." Gu Daiyan's eyes turned cold. If a person was being bullied, then even if she had to do it, she had to be the one who bullied others.

"Do you really have to?"

"Heh." Gu Liuyan only chuckled. There was some confusion outside the window. She opened the window and looked down. She could not help but smile as she muttered to herself: "They are well-informed."

In just a short moment, a shop assistant shouted loudly and pounded on the door with all his might.

"Lady! A lot of people are looking for you downstairs! "

"He's coming." Gu Liuyan only nodded. Duan Chengxuan frowned slightly, but he didn't know who the person who had arrived was. He put down his things and followed Gu Daiyan downstairs.

When he arrived downstairs, Duan Chengxuan saw a few burly men sprawled by the table. Cheng Shan walked over and said, "They've all been poisoned."

It was also these few people who told Gu Ming the location of the Tobacco Dragon Saliva, and Duan Chengxuan only glanced at Gu Danyan.

The latter had already walked up to those people, bent down, and put on gloves to take off their sabers. There were already a lot of people surrounding them, just wanting to watch the show.

"Have you all not discovered where this poison came from?" Gu Daiyan patted his cheek, randomly picked one out and fed him a pill.

Duan Chengxuan's eyes were only cold as he thought about how Gu Liuyan seemed to have touched the hilt of his saber before he left.

"Aunt …" Miss, we were entrusted by others to do things for others. " The man's limbs were still sore and weak, but his body was no longer in pain and the black color on his wrist had mostly disappeared. He only said with red eyes, "We are not going to fight over this Grass Dragon's Saliva with the girl! "Please give us the antidote, Miss."

"Nope." Gu Danyan rolled his eyes: "I've already gotten the Grass Dragon Saliva, I just need you guys to do one thing."

"We'll do anything!" The man quickly got up.

After Gu Pingyan said that, the man's expression changed. After staring at her for a long time, he nodded seriously. After getting the medicine from Gu Pingyan's hands, he rolled away and disappeared.

"What did you make them do?" Duan Chengxuan walked up the stairs with her shoulder to shoulder as he asked her in a low voice.

"Grass Dragon Saliva is an extremely poisonous saliva from another country. It can slowly kill people without them noticing, but its price is extremely expensive. Even if grass dragon saliva were to be used as medicine, it would only be used a little." Previously, when the Fourth Prince was poisoned, there was this Grass Dragon's Saliva. Although it was only a small amount, it is indeed present. " Gu Danyan could only stare coldly.

The black market owner was not a good person to be able to transport this poisonous substance.

As soon as he returned to his room, Duan Chengxuan only looked at the various superstitions that the Duke's Mansion had sent over, and it was unknown how many things Gu Daiyan had brought over, but she had even set up several mechanisms within the room. There were several times where if it wasn't for Duan Chengxuan, she might have been stabbed and injured while setting up the trap.

Gu Liuyan didn't care about his life.

However, neither of them knew that the Jianghu people outside the door as well as the gangsters knew that there was a girl who was very powerful. They asked all over for information and only thought that one of them had just come from Lingnan and hurriedly said, "That person, ah, but his ears are clear, he is a very extraordinary person. If you offend her, she will poison you and if you are injured, she will save your life without asking for anything in return."

"She is pretty, but her personality is weird. I even heard that she is a descendant of the Yun family. Her personality is probably not a traitor of the Yun family. She has been living in the underworld recently, and she has only been spending money, but no one knows who is behind her."

A few people were discussing amongst themselves, but they didn't know that these two words had reached their ears very soon.

In the evening, the black market owner sent someone over.

Before Cheng Shan could make his move, the group of assassins had already fled.

These mechanisms actually didn't have any hidden arrows. They were all poison, but they didn't really take their lives.

Deep in the night, Gu Danyan waited for the people outside the door to run away and only lightly smiled. Duan Chengxuan, who was on the other bed, said in a low voice, "You want the person who lured Mirage to appear?"
