saw her blush, and he quickly kissed her on the cheek. He looked at Xi'er, who was gazing up at him with a pleased expression, "This king has already made it known. Without your consent, Feng Linglon..."My lord, someone is blocking the carriage."

Dugu Cheng supported Feng Lingxi to sit down. Hearing Ye Xi's voice, he motioned for Feng Lingxi not to come out. He lifted the curtain and came out, looking at the masked man standing opposite him, his eyes narrowed, "Who are you"

That person turned to look at Dugu City, his voice extremely cold, carrying a hint of suppressed anger. He took out a letter from his bosom and handed it to Dugu City, "This is a letter for the Fourth Princess in the carriage. Please pass it on to the Fourth Prince."

Dugu Cheng took it, and the man then flew onto the roof and disappeared.

Feng Lingxi stepped out of the carriage and looked at Dugu City, "What's going on"

Dugu City passed the letter in his hand to her, "Just now a man in black gave this to the king to give to you."

Wind Lingxi took it, but instead of opening it immediately, she took out a handkerchief and wrapped it up. She said to Dugu City, "Get in the carriage first, and we'll talk later."

The carriage arrived at Li Wuyan's pharmacy. Just like in the past, business within the pharmacy was still bustling. The young apprentice was busy attending to customers, while Li Wuyan sat seeing patients. Most of his time, however, was spent tinkering with his medicinal herbs in the courtyard.

Feng Lingxi and Dugu Cheng came to the backyard, looking at all the medicinal herbs drying on the ground, and walked towards Li Wuyan.

"Doctor Li."

Feng Lingxi shouted, Li Wuyan stood up when he heard the voice, looking at Feng Lingxi's complexion, his brow furrowed, "How could the Fourth Prince and Fourth Princess come to see me"

Wind Ling Xi took the letter from her bosom, "Someone gave me this on my way here. I was going to open it when I arrived."

Li Wuyan looked at the handkerchief in her hand, his eyebrows raised slightly, "You suspect someone poisoned this"

"It's always good to be cautious about things you don't know the origin of."

Feng Lingxi's words made Dugucheng frown. He thought Xier suspected there was something wrong with the letter, but he didn't expect that she just kept a watchful eye. Just, Feng Lingxi's idea was right.

"This letter indeed has problems."

Li Wuyan took the letter, gesturing for them to step back. He took out the paper inside and opened it, revealing a blank sheet.

"This is..."

Li Wuyan met their suspicious gazes and calmly said, "This paper was soaked in a special potion and then dried. Once it gets wet, the potion makes the writing appear, and at this time, the smell of the potion will poison those nearby."

Li Wuyan finished speaking and poured a basin of water. Feng Lingxi watched Li Wuyan's skilled movements, wanting to step forward, but was stopped by Dugu Cheng.

"Be careful."

"Hold a damp towel over your nose, and the effect of this medicine will last only for a while. Once it's gone, it will dissipate."

Li Wuyan gave them a damp towel and covered his nose as well. He placed the letter on top, and the writing slowly appeared, densely packed all night long. The water's color gradually became purple. Feng Lingxi and Dugu Cheng didn't dare to get too close. After a while, Li Wuyan put down the towel and picked up the paper.

"This is a very ancient poison technique. I discovered it when I was reading ancient books. Basically, no one practices this technique anymore. I didn't expect to see it reappear in the world."

Feng Lingxi looked at the paper Li Wuyan had taken out, full of doubt.

"How did you determine at a glance that this was poison"

Li Wuyan held a handkerchief, the white silk had a faint purple tint at one corner. Though it was just a subtle hint, Li Wuyan saw it and that's how he deduced this possibility.

"Fortunately you wrapped it up. If you had opened it directly, the content of this letter would have been blank. You would definitely have thought to water it or use a method like I just did. Either way, it would have poisoned you."

"How could the other party know we would definitely use water to read the message"

Dugu Cheng was puzzled, looking at the characters above. He had never seen such characters before and didn't know what they meant.

Then it's easier.

Li Wuyan looked at Feng Lingxi, "You opened this letter, and since you couldn't see the writing on the surface, you would have examined it carefully. But now that you see it, with the handkerchief wrapped around it, it will be poisoned. Let alone if you were to look closely."

Feng Ling hurriedly grabbed Dugu Cheng's hand and felt his pulse. She had touched him just now and was afraid he had been poisoned.

"You're just passing it around, you won't get poisoned."

Li Wuyan washed his hands and wiped them dry, "The content of this letter is very old. I don't know what it says. Whether to keep it or not, you decide for yourselves."

“Can you tell what’s written on this” Dugu Cheng asked. The paper was peculiar; it had been soaked in water but showed no signs of tearing or crumbling. Perhaps knowing the content would reveal the sender's intentions.

"I'm not sure about that."

Li Wuyan looked at Feng Lingxi, "If the Fourth Princess has some research on these things, she might as well take a look."

Feng Lingxi twitched her lips. How could she possibly know Before, this body belonged to a foolish girl; how could it have such abilities

Since the text is ancient, she wouldn't even know it.

"Let's keep it for now. Maybe we can ask the Chief later, he might know what it is."

Feng Lingxi finished speaking, retracted her gaze, and didn't want to discuss the issue further.

Anyway, she was clear about the other party's intentions; they wanted her life. She really wanted to know, how many people had she offended How could so many people want her dead

Dugu Cheng responded, looking at the situation in Li Wuyan's courtyard, "If Doctor Li needs anything, just ask this king."

"That's enough."

Li Wuyan looked at Feng Lingxi, "The Fourth Princess has been taken care of."

"Li Wuyan, I'm asking about someone. Do you know the owner of Tianxiang Building"

"Heard that." Li Wu Yan raised an eyebrow, looking at Feng Ling Xi's eyes instantly brightening. "What did the Fourth Royal Princess ask him to do"

Feng Ling Xi told Li Wu Yan about Tian Xiang Lou's master looking for her. After listening, Li Wu Yan calmly said, "If he is entrusted by someone, he will definitely protect the safety of the Fourth Princess. As for other matters, the Fourth Princess does not need to investigate. The Jianghu (martial arts world) is searching for him, but no one has ever seen his true face."

"I just want to know who's having him watch over me."

Feng Lingxi's mind was filled with many possibilities. Huangfu Qingyun, her mother

After her mother fell off the cliff following the Yao Clan incident, she never appeared again. Huangfu Qingyun had also been out of contact for a long time. Moreover, with so many things happening in the Aoxiang Dynasty, Huangfu Qingyun couldn't possibly have come here to find the mistress of Tiangxiang Building to help her.

Feng Lingxi shook her head, "Forget it, my head hurts. Let's go to Tianxiang Lou for dinner."

Li Wuyan bowed and said, "I won't go. I have something to do."

Feng Ling Xi only then thought to ask about Luoli’s whereabouts, she hurriedly asked, "Li Wu Yan, is there any news of Luoli Has he said when he will be back"

"No news yet, I will let you know when there is."

Feng Lingxi thanked him and, along with Dugu City, went to get the herbs before heading to Tianxiang Building for a meal.

This time, when Feng Lingxi went to Tianxiang Building, she asked the manager about Chu Xi, but Chu Xi was not there. It was said that she had not appeared for several days. Feng Lingxi and Dugu City sat by the window, looking at the bustling streets below, lost in thought.

"Could it be that the OP has already left"ncess."獨孤雁聽到這裡，劍眉一挑，“他有冇有說什麼？”Feng Ling Xi shook her head, "No, he's just in a bad mood.""So you and he..."Du Gu Yan spoke as soon as she thought of it, realizing that she had been too blunt. Feng Lin...
