My husband married a concubine? I turned around and married the cold prince.

Tianshu then recounted in detail everything that had just happened in the study.

After hearing what Tianshu said, Shi Qiuwu paused and nodded slightly to indicate that he understood.

"Nothing?"

"Prince, I didn't find anything and Prince Yong came back." Tianshu looked guilty.

He made a special trip, but it was in vain and he was injured, so he asked the prince to save him.

"Go and bandage the wound." Shi Qiuwu did not blame Tianshu. He just waved his hand and sent him away.

"Sir, I have another question."

"Speak." Shi Qiuwu put the small porcelain bottle on the table and spoke casually.

"Prince, was the thing that man gave you just now poison?" Tianshu asked carefully.

Just now he saw the man in black throw a small porcelain bottle over. Yes, it was the small porcelain bottle that the prince was holding in his hand.

"No, and she is an acquaintance of ours." Upon hearing this, Shi Qiuwu curled up the corners of his mouth, opened the small porcelain bottle and smelled it.

"Acquaintance?" Tianshu keenly grasped the key words in Shi Qiuwu's words.

"Go away." Shi Qiuwu did not reveal An Qingqian's identity and sent Tianshu away.

The room became quiet again. Shi Qiuwu stared into the void and muttered to himself.

"An Qingqian, what is your purpose in going to Prince Yong's Mansion?"

The reason why Shi Qiuwu was able to see through An Qingqian's identity was because he was good at medicine and was extremely sensitive to smells.

Not to mention that people who have seen them can remember their smell, and those who are familiar with them must know it,

Just now in front of Prince Yong's Mansion, he attacked that person with a palm, and he also smelled the scent on her body as the palm wind passed by.

He recognized that the person in black in front of him was An Qingqian, so he took the small porcelain bottle she threw to him.

Moreover, he was sure that An Qingqian saw his face and realized that Tianshu was his man, which was why she stopped attacking him and threw him a bottle of medicine.

Shi Qiuwu looked at the medicine and thought it was a good medicine for healing wounds.

However, Shi Qiuwu was very confused. What was An Qingqian looking for when she sneaked into Prince Yong's study in the middle of the night wearing a nightgown?

An Qingqian returned home, changed out of her nightgown, and picked up the letter again.

She opened the letter decisively, and the content of the letter was indeed related to her.

Liu Yiyi said in the letter that she had suffered a lot of injustice here. An Qingqian had embarrassed her many times and made it difficult for her to do her job. She had suffered so much humiliation that she could hardly survive here.

After making up a story out of thin air, Liu Yiyi asked her father to think of a way to send over a chronic poison that could kill people slowly without anyone noticing.

It seems that the development of some things is still the same as in the previous life.

Liu Yiyi knew that only if she died could she have a formal identity.

After reading the contents of the letter, An Qingqian thought for a moment, changed into casual clothes, and went directly to Prince Xian's Mansion.

Before, at the gate of Prince Yong's Mansion, Shi Qiuwu stared at her with a strange look in his eyes. An Qingqian was not sure whether he recognized her or not.

However, since he sent people to secretly check Prince Yong's study, it means that the relationship between him and Prince Yong is not good.

Maybe I can get something from him.

An Qingqian concealed her figure and went directly to Shi Qiuwu's yard.

Seeing that there was a candle on in his room, I guessed that he was not asleep yet.

An Qingqian rolled over and landed directly in front of the door. A guard holding a long sword quickly rushed over.

The guards next to her did not recognize An Qingqian and thought she was an assassin, so they attacked her directly.

An Qingqian pushed the guard back with a palm and wanted to break in, but then he remembered that he came here today to seek cooperation with him.

So he retracted his steps and prepared to knock on the door to go in.

The door of the room suddenly opened from the inside, and Shi Qiuwu stood in front of the door, looking at her.

"Prince." The guard saw Shi Qiuwu appear and was about to explain, but was interrupted by Shi Qiuwu.

"Go down."

"Yes." The guard turned around and left without any hesitation, but he was a little puzzled.

Why would a woman with great martial arts skills come to see the prince in the middle of the night?

"It's the dead of night, and I'm sorry to bother you, Your Highness." An Qingqian looked at Shi Qiuwu.

"It's okay, come in."

The guard returned to his original position and looked over there, only to see that the door was closed and no one knew what the people inside were talking about.

"Prince, the man in black in front of Prince Yong's Mansion just now was me." Regardless of whether Shi Qiuwu recognized her or not, An Qingqian told the truth about what happened just now.

Shi Qiuwu paused for a moment. He didn't expect An Qingqian to admit it on her own initiative.

"Miss An, why are you here today?" Shi Qiuwu poured a cup of tea for An Qingqian and placed it in front of her.

"Prince, I came here today to ask you if you have ever seen this kind of thing." An Qingqian took out a piece of paper from his arms. The pattern on it was exactly the same as the ink pattern on Liu Yiyi's envelope.

It was also the pattern on the handkerchief on the couch in the study of Prince Yong’s mansion.

Shi Qiuwu took the paper, stared at the pattern on it carefully, and had an idea in his mind.

"This is a poisonous flower called Zixiao. The bud is pink and the flower turns purple after it blooms. The flower is gorgeous. When the flower is in full bloom, you can pick it and mix it with other medicinal herbs to make a poison."

"What poison?" An Qingqian looked at Shi Qiuwu seriously.

"This poison is called Luohui. Those who are poisoned by it will become unconscious, weak all over, and slowly die. It is extremely difficult for ordinary doctors to detect it." Shi Qiuwu said, staring at the person in front of him calmly, paying attention to her reaction.

Sure enough, when An Qingqian heard the word Luohui, his expression changed drastically. When he heard that Zixiao was one of Luohui's raw materials, his expression became even more unsightly.

"Does the prince know Luo Hui?" An Qingqian narrowed her eyes and looked at Shi Qiuwu.

Last time, the divine doctor Wutong said that he didn't know much about Luohui, but had only heard of this poison.

Shi Qiuwu not only knew about this poison, he also knew one of its raw materials and knew how the human body would react after being poisoned.

Does he have the antidote for Luohui, or does he know the formula for the antidote for Luohui?

"I know." Shi Qiuwu did not deny it. He knew that An Qingqian had been looking for the antidote for Luo Hui.

"Does the prince know the antidote for Luohui?" An Qingqian paused, but still couldn't help but ask.

She had sent people to investigate for such a long time, but there had been no news. Now that there was finally some news, she really didn't want to take a detour or keep it a secret.

"Why are you so interested in Luohui?" Shi Qiuwu raised his eyebrows, very curious.

The poison Luohui is extremely rare and may not appear in the entire capital. An Qingqian is not a medical student and there is no one around him who has been poisoned by it.

Why was she so eager to investigate Luo Hui?

"Your Highness, this is my private matter." Upon hearing this, An Qingqian pursed her lips and looked away.
