A four-year-old medical prodigy descended to the mortal realm, and the entire capital sought her tre

Zhao Jinzhong returned quickly, carrying a lemon.

Arriving at Zhou Ruo's bedside, Zhao Jinzhong handed her a lemon.

"Ah, yes, yes! That's the fruit!"

Zhou Ruo, her eyes sparkling, happily took the lemon and immediately started munching on it.

"It's so delicious!" Zhou Ruo took two big bites before realizing that Zhao Jinzhong and Granny Wang were staring at her.

They looked at her with eyes that seemed to regard her as a monster, their brows furrowed so deeply they could hold bamboo sticks between them.

Zhou Ruo suddenly stopped chewing the lemon. She looked at the lemon in her hand, and then at the two people in front of her.

Then, with a hint of reluctance, she stretched out her hand, still holding the lemon: "Brother, Granny, would you like to try some?"

Granny Wang leaned back and immediately refused, saying, "Miss, I'm too old to eat this."

Zhou Ruo looked at Zhao Jinzhong again and saw him shake his head.

Zhou Ruo let out a long breath and said in a low voice, "You scared me! I thought you wanted to share my fruit!"

"Ruoruo," Zhao Jinzhong's mind was filled with a million questions, "what other abilities do you have that we don't know about?"

Who in their right mind can eat two lemons in one go?

Zhou Ruo didn't quite understand Zhao Jinzhong's meaning, and just kept chuckling as she ate her lemon.

Even after finishing the second lemon, she still wanted more.

"Not...not enough?" Zhao Jinzhong panicked a little. Wouldn't it make this little person sick from eating sour fruit like this?

"Oh..." Zhou Ruo rubbed her lower belly, she really wanted to eat more.

Zhao Jinzhong glanced at the food on the table behind him, then lifted Zhou Ruo off the bed and placed her on the chair in front of the table.

"If you're still hungry, we'll have roasted pheasant, braised wild rabbit, white rice, and boiled sweet potatoes," Zhao Jinzhong said to Zhou Ruo, pointing to the food on the table.

Zhou Ruo was extremely disappointed, and frowned as she complained to Zhao Jinzhong, "Brother is mean!"

Zhao Jinzhong sighed helplessly, then went out of the tent to retrieve a lemon and placed it on the table.

A smile instantly bloomed on Zhou Ruo's face.

"We'll eat them together," Zhao Jinzhong said.

The flowers on Zhou Ruo's face had wilted halfway.

She reluctantly picked up a sweet potato, took a bite of lemon, and then ate a bite of sweet potato.

"Meat." Zhao Jinzhong pointed at the rabbit with his eyes, then simply broke off a rabbit leg and put it in Zhou Ruo's bowl.

Zhou Ruo took two bites of lemon and then a bite of meat.

Soon, the third lemon was finished.

"Burp~ I'm full!" Zhou Ru patted her tummy, feeling very satisfied and comfortable.

But the next second, she felt a surge of energy rising within her body.

The energy first surged wildly through Zhou Ruo's body, then circled around a few times before returning to her abdomen and rotating continuously in a Tai Chi shape.

Zhou Ruo felt something tickling her stomach, so she covered her stomach and squatted down on the ground.

Zhao Jinzhong thought she had an upset stomach from eating lemons, and his heart tightened.

Just as he was about to squat down to check on Zhou Ruo's condition, Zhou Ruo suddenly scooted over and lay down on the ground, clutching her stomach and laughing out loud.

Zhao Jinzhong and Granny Wang were dumbfounded.

Granny Wang was very worried about Zhou Ruo and asked anxiously, "What happened to Miss? Please don't let her be poisoned!"

If I eat three lemons and then eat other things, could there be a food poisoning reaction?

Just as Zhou Ruo was laughing so hard he could barely stand it, the energy within his body suddenly stopped.

The voice in his mind rang out again: "The effect of the Yin Poison Core Formation has been enhanced; the stronger the toxicity, the stronger the effect of the Spiritual Power Core Formation!"

Hmm? Zhou Ruo sat up, scratching her head with one hand, staring blankly at Zhao Jinzhong.

"Ruo Ruo, how are you? Is your stomach hurting? Or is something else bothering you?" Zhao Jinzhong was getting increasingly anxious.

Zhou Ruo: "Brother, I'm not feeling unwell, it's just... my head is ringing again..."

Zhao Jinzhong: "What's all the noise about?"

Zhou Ruo: "It said, 'Poison, Core Formation,' it seems to mean... the more poisonous, the more powerful my elixir!"

Zhao Jinzhong didn't quite understand, and he asked hesitantly, "Ruoruo, did you eat too many sour fruits just now and make yourself sick?"

Sour fruit? Could it be that eating sour fruit accelerated the formation of the Yin poison in my body?

Zhou Ruo wasn't sure either. She shook her head and said, "I don't know..."

Zhao Jinzhong sighed helplessly and carried Zhou Ruo back to the bed.

He felt that Zhou Ruo was illiterate and didn't read, so she couldn't understand many of the things he said.

"Ruoruo, you need to study more. From today onwards, your brother will teach you to read and write!"

As he spoke, Zhao Jinzhong took out a copy of the Thousand Character Classic from his pocket.

"There aren't many books suitable for you in the army. I found this one among the soldiers, and it's perfect for you to learn to read."

Zhou Ruo took the "Thousand Character Classic" and read it over and over again several times.

She saw that there were indeed many words inside, which were very similar to the words she had seen when Doctor Yu wrote the prescription.

"This is a book?" Zhou Ruo had never seen a book in the mortal realm look like this before.

In her previous life in the Immortal Realm, she could read books simply by opening them in the air in front of her.

There's no need for such a angular thing to hold those words.

Zhao Jinzhong's heart tightened, and he asked, "You've never seen a book before?"

Everyone says they've seen chickens run even if they've never eaten chicken, but Zhou Ruo has never even seen a book; she's really pitiful.

"I've never seen a book like this before." Zhou Ruo randomly opened a page. "Brother, teach me quickly, I learn fast!"

Granny Wang watched the brother and sister sitting on the edge of the bed reading, a very harmonious scene.

She couldn't help but sigh, "The young general was a brilliant student when he was young; he always received praise from his teachers."

Zhao Jinzhong was secretly pleased to be praised by Granny Wang.

He raised his face, sniffed, and gave Zhou Ru a lecture-like look.

"Ruoruo, you don't have to be like your brother. You're young, it's good enough if you can read one page a day."

Zhou Ruo: "How long did it take you to read this book before, brother?"

Seemingly referring to Zhao Jinzhong's strengths, he said with some pride:

"Back then, my brother didn't just read it; he could memorize the whole book in three days."

Hearing Zhao Jinzhong say this, Zhou Ruo couldn't wait any longer, "Then brother, please teach me quickly!"

"Heaven and earth were dark and yellow, the universe was vast and boundless..." Zhao Jinzhong quickly finished reading a page.

Zhou Ruo followed along, whispering the words to him, learning very diligently.

Zhao Jinzhong handed the book to Zhou Ruo, "Alright, you only need to read this page today. We'll read the second page tomorrow."

"Hmm—" Zhou Ruo pouted and shook her head.

"What's wrong? You still can't do it?" Zhao Jinzhong asked, somewhat disappointed.

Zhou Ruo: "Brother, that's too little. Please teach me more."

Zhao Jinzhong was taken aback, then smiled gently at Zhou Ruo.

"Ruoruo, don't worry. If you can recognize all the words on this page today, that will already be very impressive."

Zhou Ruo asked, puzzled, "But I already know it all, why won't you teach me more, brother?"

"You...you know it all?" Zhao Jinzhong felt that Zhou Ruo was teasing him. "Then recite it to your brother."
