The three-year-old host decides to raise an emperor father for himself.

Whether he was poisoned or not, Xuan Yuanjing himself couldn't say for sure.

However, this was confirmed by Xiao Lanxing.

When Wang Tai arrived at the villa, Xuan Yuanjing had already lured Xiao Lanxing away, preventing Wang Tai from seeing the little girl up close.

But for Xiao Lanxing, although the handmade room that her father specially set aside for her was very interesting, her father was definitely more important.

After confirming that the so-called guest had left, Xiao Lanxing ran over to find Xuan Yuanjing. As soon as she entered, she sniffed and frowned: "Poison?"

At that time, Wang Tai and Liu Fubai had been gone for less than a quarter of an hour. Because the room was relatively closed off for warmth in winter, some of the smell had not completely dissipated, but there was not much left when the curtain was lifted a few times.

Even with just that tiny residue, the little girl still noticed it.

The smile on her face vanished instantly, and she frowned, appearing beside Xuan Yuanjing in the blink of an eye. "Father? Hand."

Xuan Yuanjing was slightly taken aback. Even he hadn't expected such a scene. After a moment of stunned silence, he came to his senses and found that the little girl had already taken matters into her own hands and was taking his pulse by feeling his wrist.

Putting everything else aside, the little girl's posture is quite impressive.

Pei Qingzhu stood to the side, her gaze showing a hint of surprise, but not quite shock, which quickly turned into understanding.

Indeed, didn't we already know that this young princess was skilled in medicine?

Pei Qingzhu was also puzzled. Even if such a young child learned some medical skills and pharmacology, to what extent could he learn them?

However, he wasn't lacking in emotional intelligence. With Xuan Yuanjing's ambiguous remarks, Pei Qingzhu knew when to turn a blind eye.

Seeing the girl's solemn expression and recalling the conversation between the two, Pei Qingzhu's heart skipped a beat. She held her breath and watched the two of them intently, extremely nervous.

Xuan Yuanjing, on the other hand, was quite calm. While letting the little girl take his pulse, he said with a smile, "Why did Xingxing come so quickly? Daddy was just about to go look for you."

After feeling the man's pulse for a while, Xiao Lanxing clung to his legs, climbed onto him, and sniffed him from left to right, as if trying to identify something.

Xuanyuan Jing cooperated throughout, and only after the little girl finally calmed down and sat down in his lap did he ask, "Did Xingxing discover anything?"

Xiao Lanxing tilted her head, a hint of doubt in her eyes, but still answered honestly, "It's poisonous, but..."

Little Lanxing's little head was filled with questions: [Huh? Why... that's strange, why are the poisonous and the antidote mixed together?]

Xiao Lanxing didn't understand.

Xiao Lanxing couldn't understand it.

Xiao Lanxing's head is about to explode!

Xuan Yuanjing, who clearly heard her thoughts, paused for a moment before smiling gently and pulling the girl into his arms. He then picked up a prescription from the side and said, "Oh, right, Father doesn't know much about pharmacology. A royal physician just took Father's pulse and left a prescription. Xingxing, would you like to take a look?"

Upon hearing this, Xiao Lanxing immediately snapped out of her thoughts and nodded hastily.

Then, Xiao Lanxing received the prescription.

She was even more confused.

Xiao Lanxing: "Huh?"

Pei Qingzhu finally couldn't hold back any longer and asked, "Little Princess, is there a problem? Also, has the Prince been poisoned?"

If it were anything else, Xiao Lanxing might not have responded immediately.

But when Xuanyuan Jing is mentioned, she will still take the initiative to answer, "Daddy is fine."

As she spoke, she tilted her head with a hint of confusion, a question mark practically appearing on Xiao Lanxing's face: "Incense?"

[Did you create this scent to make yourself smell nice?]

Then, knowing it was poisonous, he made his own antidote sachet.

Although Xiao Lanxing believed that even if the fragrance was poisonous, it would not be immediately fatal and would be considered a slow-acting poison.

Poisons that can kill upon inhalation are rare, and their production methods are extremely time-consuming. There's also a certain probability that the poison maker will die from poisoning themselves during the process.

There is a chance to solve chronic toxicity, unless someone develops a compound, which would be very troublesome.

Xiao Lanxing: [Huh, what's a compound again?]

The system remained silent, letting the various pieces of knowledge flash through the little girl's head.

Pei Qingzhu: "Are you alright?"

Xiao Lanxing snapped out of her daze, turned to meet Pei Qingzhu's worried gaze, and nodded: "It's okay."

Using incense to harm people is a long-term strategy. Only occasional contact with such individuals is possible under certain preconditions, such as long-term use of a certain drug leading to the accumulation of toxicity in the body.

However, this requires the poisoner to know the list of drugs used by the victim beforehand and to have a deep understanding of pharmacology.

If it were Xuan Yuanjing two months ago, Xiao Lanxing wouldn't be able to remain so calm right now.

At that time, Xuanyuan Jing was truly weak, with all his bodily functions at a low point and his resistance very low.

Therefore, when Xiao Lanxing noticed someone approaching Xuan Yuanjing with a fragrance that could weaken people, she pushed the person away without thinking, without considering whether she would be scolded as a brat for doing so.

The situation is much better now.

Xiao Lanxing: [Thankfully, Daddy is much healthier now. Otherwise, a month ago, even after detoxification, he would have felt unwell for several days.]

Xuanyuan Jing's eyes flickered.

Unlike the little girl, Xuanyuan Jing had more to think about.

Xuanyuan Lin probably didn't know about his relationship with Liu Fubai, otherwise things wouldn't have turned out this way today, and Wang Tai wouldn't have left so easily.

But if that's the case, what's the point of Liu Fubai meeting him only once today, and wearing this incense that requires long-term use to be effective?

Xiao Lanxing has her own doubts.

Xuanyuan Jing also had his own doubts.

But Xuanyuan Jing didn't intend to continue the topic in front of Xiao Lanxing. He just affectionately rubbed the little girl's cheek and said, "It's probably just that the guest who came today accidentally picked up the scent somewhere. Since it's nothing, that's fine. Anyway, Daddy may not see him again in the future."

Pei Qingzhu looked at him with a puzzled expression.

Xuanyuan Jing seemed oblivious and continued to ask about the prescription: "Can Xingxing understand this prescription? If there's a word you don't recognize, you can tell your father."

Xiao Lanxing: "...I don't quite understand."

On this so-called prescription, she didn't know who wrote it. The handwriting was so flamboyant that she could only vaguely make out a few easy characters. She couldn't recognize anything that was slightly more complicated.

She even suspected she was holding it upside down, so she flipped the paper over with her little paws and looked at it carefully again.

The little girl's eyes seemed to start swirling.

Pei Qingzhu: "...This Lord Liu's handwriting is a bit difficult to decipher."

For toddlers who have only recently begun to learn to read, cursive script can indeed be quite challenging.

Especially cursive script.

Although Xiao Lanxing has been learning to read for a while, it's still difficult for her to recognize the characters.
