"Sister Bicao, come and catch me! Sister Bicao, come quickly!" Jun Yanyan ran ahead.

"Little princess, don't run, be careful not to fall." Bicao carefully carried a bowl of medicine and chased after her.

"Yan Yan." When Jun Molin saw Jun Yan Yan, a gentle smile appeared on his handsome face.

"Father, Mother!" Jun Yanyan saw the two of them and ran towards them.

"Mother?" Yun Qingran turned around and looked around, but there was no one there. So who was Jun Yanyan calling "Mother"?

Before she could figure it out, Yun Qingran felt someone hug her thigh. Looking down, she saw Jun Yanyan and exclaimed, "Mother, you've come to see me!"

Yun Qingran quickly squatted down, took Jun Yanyan's hand to check her pulse, and exclaimed, "Huh, her pulse is fine! She hasn't been driven mad by the fever."

"Mother, what's wrong with me?" Jun Yanyan asked, tilting her head.

"Yan Yan, I'm your older sister, not your mother. You've called the wrong person," Yun Qingran quickly corrected.

“But you said yourself that day that you were my mother,” Jun Yanyan said pitifully, clinging tightly to her leg.

"You had a fever of almost 40 degrees Celsius back then, and you still remember?" Yun Qingran was surprised that Jun Yanyan still remembered what happened that day.

Jun Yan nodded. "I remember."

"Yan Yan, she is Yun Qingran, not your mother. Let her go." Jun Molin squatted down and pulled Jun Yan Yan's hands away from Yun Qingran.

"Oh." Jun Yan Yan nodded in disappointment, then let go.

"Young Miss, has a cure for the Corpse Plague been found?" Bicao looked at Yun Qingran with hopeful eyes.

Yun Qingran's expression immediately turned serious, and she shook her head. "No."

Bi Cao noticed that Yun Qingran was in a bad mood and quickly comforted her, "Miss, you are the best. You will definitely find it. Even if you don't find it, it's okay. It's not your fault. You have already done your best."

"Hmm." Yun Qingran nodded, then looked at the medicine in her hand. "Is this Yan Yan's medicine?"

"Yes, this is the little princess's medicine." Bicao said with distress, "The little princess hasn't taken her medicine all day, and she won't take it no matter how I coax her."

"Yan Yan, why aren't you taking your medicine? What will happen to your body if you don't take your medicine?" Yun Qingran squatted down in front of Jun Yan Yan and asked her in a low voice.

"Because Yan Yan is better now." Jun Yan Yan spun around.

Yun Qingran touched Jun Yanyan's forehead; the fever had subsided. Then she took her pulse.

"Hmm?" Yun Qingran responded with a puzzled "hmm".

"What's wrong?" Jun Molin asked, then asked in a low voice, "Is something wrong?"

"Yan Yan's corpse disease has mostly healed!" Yun Qingran turned her head and looked at Jun Molin in disbelief.

Yan Yan is young and in poor health with a low immune system. Logically, her condition should be more serious than that of an average adult. But why did her condition not only not get worse, but actually improve?

There must be some special reason. Yun Qingran's eyes lit up instantly, like fireworks exploding with starlight.

"Bicao, has Yan Yan eaten anything special these past two days, or had any special experiences?" Yun Qingran asked Bicao.

After thinking for a while, Bi Cao said, "No, although I made the food for the little princess myself, the ingredients were all taken from the kitchen. She didn't have any special experiences either. She was either sleeping and reading in the prefab house or playing outside."

"Really not?" Yun Qingran asked anxiously.

“Young Miss, really no. The young princess didn’t eat anything special, nor did she have any special experiences,” Bicao replied affirmatively.

"What could be the cause?" Yun Qingran stood up and paced back and forth.

Jun Yanyan, Bicao, and Jun Molin all remained silent, not wanting to disturb her thoughts.

Passersby were curious when they saw Yun Qingran's appearance. They all stopped and quietly looked at her, wondering what was wrong with Miss Yun.

"There must be something I've overlooked. What is it? What could it be?"

"Could it be that Yan Yan's constitution is special? No, apart from the poison in her body, she is no different from an ordinary person."

"Poison! Yan Yan has a congenital poison in her body. That's it! It must be the poison. I've finally figured it out!" Yun Qingran excitedly raised her head, her eyes shining brightly!

"Have you figured it out yet?" Jun Molin could tell from her expression that she must have thought of a way to detoxify.

“Well, I’m not sure if my idea is right, I can only experiment with it,” Yun Qingran replied.

"What do you need?" Jun Molin didn't ask any more questions, only what she needed, and he would prepare whatever she needed.

“We need poison, lots and lots and lots of different kinds of poison.” Yun Qingran looked at Jun Molin.

"Very well, I will take care of it immediately," Jun Molin replied.

"Hey, why didn't you even ask me why I wanted the poison?" Yun Qingran reached out and grabbed Jun Molin's sleeve, then let go as if it were too hot to handle.

"You must have your reasons for wanting poison. Why should I ask you?" Jun Molin retorted.

"Oh, go ahead." Yun Qingran's heart skipped a beat, but only for a moment.

Jun Molin turned around and ordered someone to prepare poison.

Bystander 1: See? I told you Miss Yun and His Highness the Northern Cold King were having an affair.

Bystander 2: Ugh, this is so sweet it hurts my teeth!

Bystander 3: Even though Miss Yun wants poison, His Highness the Prince of Beihan doesn't question it. If Miss Yun commits murder one day, His Highness the Prince of Beihan will probably hand her the knife.

...

Two hours later, more than fifty kinds of poisons were neatly arranged on the table in Yun Qingran's room.

"Your Highness, Prince of Beihan, tell me secretly, how do you have so much poison? Are you secretly doing something bad?" Yun Qingran leaned closer to Jun Molin and asked furtively.

Jun Molin swallowed hard and took three steps back. "Boring."

"Just kidding." Yun Qingran pouted.

Jun Molin glanced at her seemingly casually, his brows relaxed, and his features softened considerably.

She finally regained her energy and became happy again!

"You can all leave now. I need to start developing the antidote." Yun Qingran shooed everyone out of the room.

“I am right outside the door. If you need anything, just call me,” Jun Molin said.

He felt uneasy, with a bad feeling.

"Don't worry, I'm an expert in both medicine and poison, there won't be any problems." Yun Qingran smiled faintly. Her smile was like countless lotus flowers blooming instantly, beautiful and radiant, as if nothing could faze her.

"Mm." Jun Molin nodded.

Yun Qingran closed the door, and the smile vanished the instant it closed. She took a deep breath and cheered herself up!

Yan Yan contracted the plague. At first, she was just as badly ill as everyone else, but she recovered almost completely within a few days. If I'm not mistaken, it's because the toxin Yan Yan was born with suppressed and eliminated the plague's pathogen.

So she came up with the idea of ​​fighting poison with poison. But this method required constant experimentation to find a poison that could eliminate the plague without harming the host, as well as the correct dosage.

As a doctor, she couldn't experiment on others; she could only experiment on herself.

Ancestors, you must bless me!
