My master gave me a death mission: to go down the mountain and retrieve his granddaughter.

Su Muchen used his spiritual power to attach to his hands and kept manipulating the silver needles on Aunt Lan's body. The spiritual power slowly flowed into Aunt Lan's body through the silver needles, gradually repairing Aunt Lan's atrophied internal organs.

Other organs are only affected by illness, which causes cells to become inactive and atrophy. With the nourishment of spiritual energy, the cells become active again, and these organs repair themselves very quickly.

The slowest part to repair was Aunt Lan's lungs, since her illness originated from there. Su Muchen used his spiritual power to examine Aunt Lan's body and found that her lungs were already rotten and lifeless, and could stop working at any time.

It took Su Muchen a full five minutes to repair Aunt Lan's lungs and internal organs. This required a great deal of his spiritual power, and he even broke out in a cold sweat. It was clear that this treatment was quite strenuous for Su Muchen.

Su Muchen once again used his phantom-like technique to retrieve the needles. Even though the two women beside him were prepared, they couldn't see it clearly. They only felt a blur before their eyes, and all the silver needles that were stuck in Aunt Lan's body were put back into the silver needle pouch.

"Brother Su, how is my mother?"

Seeing that Su Muchen had stopped the needles, which meant the treatment was over, Luo Ying'er immediately became anxious and concerned about her mother's condition.

"Don't worry, Aunt Lan's lung disease has been cured, and her other organs have also recovered. Your mother is now just like a normal person without any illness."

"Brother Su, is what you said true? My mom is alright, yay..."

Luo Ying'er excitedly hugged Su Muchen and jumped around, her newly developed breasts constantly rubbing against Su Muchen's chest, making Su Muchen feel unbearably itchy.

Seeing Luo Ying'er's actions and Su Muchen's embarrassment, Xu Lu quickly pulled Luo Ying'er away.

"Ying'er, look at the state you've become! Don't you know that men and women shouldn't touch each other?"

"I was just a little too excited!"

Luo Ying'er playfully stuck out her tongue, glanced shyly at Su Muchen, and immediately blushed.

Seeing Luo Ying'er's change, Xu Lu felt a pang of anxiety. She knew that this teenage girl had fallen in love.

Indeed, such a young, handsome, and wealthy man, who also possesses extraordinary medical skills, would surely make any teenage girl fall in love with him.

"Luo Ying'er, don't think I don't know what you're thinking. Keep your little schemes to yourself. You're still just a high school student. You should focus on your studies and not have any weird ideas."

Xu Lu knew that if she didn't stop her, Luo Ying'er might fall for it, which would ruin her studies.

"Sister Xiaolu, Ying'er understands what you mean, so don't worry. Also, Ying'er will be an adult in half a month."

Luo Ying'er glanced at Su Muchen intentionally or unintentionally as she spoke her last words, as if she were addressing him directly.

This made Su Muchen blush deeply. So what if you're an adult? What does it have to do with me? Could this be some kind of hint to me?

[Pah, pah, pah! What are you thinking? He's still a high school student.]

Su Muchen quickly dismissed the thought in his mind and awkwardly touched his nose.

"Um... Miss Ying'er, Officer Xu is right. You're in your final year of high school now, so you should focus on your studies and not have any other bad ideas."

"Oh, Brother Su, you mean that once Ying'er finishes her senior year of high school and gets into university, she can have other ideas, right?"

Luo Ying'er's answer left both Su Muchen and Xu Lu speechless, covering their foreheads in exasperation. Well, this lustful girl had completely fallen for her.

"Mr. Su, please ignore what this young lady is saying. By the way, I take back my previous prejudice against you. I was the one who had prejudged you as one of those spoiled rich kids who prey on young girls. I apologize for that!"

Xu Lu bowed sincerely to Su Muchen to express her gratitude for her previous bad attitude.

"I was wondering why Officer Xu was so prejudiced against me when I hadn't done anything. It turns out you thought I was one of those spoiled brats. Now that you know I'm not like that, I hope Officer Xu will stop being hostile towards me in the future."

"That's natural!"

At this moment, Aunt Lan, who was lying on the kang (a heated brick bed), let out a word of advice and then slowly opened her eyes.

"Mom, you're awake. How are you feeling?"

Luo Ying'er immediately stepped forward to help her mother sit up, and anxiously inquired about her mother's condition.

"I feel like the weight on my body is gone, my chest doesn't hurt anymore, my cough is gone, and it's as if I was never sick."

Aunt Lan looked incredulous. She knew her own physical condition. Just now, she was in pain all over, especially in her chest. Even when she wasn't coughing, it was still aching. And when she coughed, it felt like a heavy hammer was hitting her chest, making her feel like she was in excruciating pain.

But now, her chest no longer hurts, she feels no discomfort in her body, and she is full of energy—a feeling she has never experienced in the past few years.

"Aunt Lan, it seems your illness has really been cured. We have to thank Dr. Su for this."

Seeing that Aunt Lan had fully recovered, Xu Lu was overjoyed.

"Xiaolu, thank you for your help over the years. If it weren't for your continued support for my daughter and me, I probably would have passed away with Ying'er's father several years ago."

Aunt Lan is very grateful to Xu Lu. If it weren't for Xu Lu's silent support over the years, she probably wouldn't have been able to hold on.

If she were to leave too, leaving Luo Ying'er all alone, Aunt Lan would not be able to bear it and would not be able to die in peace.

"Aunt Lan, please don't say that. I've long regarded Ying'er as my own sister and you as my godmother. Everything I've done for my sister and godmother is only right."

"Good, good, good. Having a goddaughter like you is a blessing that Aunt Lan has accumulated in her past life."

"Yay! From now on, Sister Xiaolu will be Ying'er's god-sister, and Ying'er has a sister now."

Luo Ying'er was overjoyed to hear that Xu Lu was going to be her god-sister. She had always been alone since she was little, without any brothers or sisters, and was often bullied by other children.

Later, her parents were also tormented by illness, which made her even more helpless. She especially hoped that she could have a brother or sister to share this suffering with her. Unfortunately, she was the only child in the family and had no opportunity to confide in anyone.

Now that she has an older sister, even if it's a male offspring, she is very happy. She will no longer be alone; she has an older sister now.

"Why are you so excited, you little rascal? I've always treated you like a little sister all these years. You wouldn't forget about your older sister, would you?"

"How could that be? Ying'er has always treated Sister Xiaolu like her own older sister."

Luo Ying'er let go of her mother and went forward to hug Xu Lu affectionately.

Seeing the two sisters so loving and affectionate, Aunt Lan felt truly happy and content.

"This must be Dr. Su. I must thank you for treating this old woman. Dr. Su, you are so young, yet you have such superb medical skills. It's truly remarkable!"

"Hehe, Aunt Lan, don't flatter the boy. His skills are nothing special."

Su Muchen's humility earned him eye rolls from the two sisters. Who was it that said he could cure anything except a severed head, and that a severed arm could be regenerated? Where did that arrogant and unruly attitude go? Why is he being so humble now?

Seeing the disdain in the two women's eyes, Su Muchen understood what they meant and awkwardly touched his nose.
