Reborn as a devoted sister-in-law, she leads the entire village to prosperity.

"It's short-tempered, easily angered, and poorly ventilated." As he spoke, he directly peeled off the blackout cloths and pushed open the window.

"Don't touch it!" came the boy's deep, stern voice from the bed.

Yu Banxia shrugged and continued working: "If you want to stop me, get up and do it yourself. I have a bad temper. If I hurt your servants or pageboys, I won't compensate you."

"Where did this audacious girl come from, daring to speak to me like that!" The boy pounded on the bed.

"Miss Yu..." Zhang Wanqing hadn't finished speaking when Yu Banxia continued her actions.

"Has the mistress forgotten her promise?" After hearing Yu Banxia's words, Zhang Wanqing finally remained silent.

When Qian Qiwen saw his mother was also there, he immediately said with displeasure, "Mother, is this a new maid you hired for your son? How dare you be so bold!"

"Doesn't she know her son's rules?"

"Sorry, I'm not your maid, I'm a doctor here to treat your leg."

Yu Banxia had already opened all the windows, letting in fresh air. Soon, the strong smell of medicine in the room dissipated a bit, and the heat also subsided considerably.

There was a bowl of ice in the corner of the room, which had almost melted.

"You? A doctor?" Qian Qiwen didn't believe it at all. He was originally a cheerful, sunny, and gentle young man.

Since breaking his leg in a horse-riding accident three months ago and becoming a cripple, he has been despondent and his temper has worsened.

"Your calves are starting to atrophy. Let me massage them for you first, and then I will treat you."

Ignoring Qian Qiwen's reprimands, she grabbed his calf with her hand.

He infused some wood-based supernatural abilities to unblock his meridians, then used his special massage techniques to massage him, before inserting silver needles into several places on his legs.

"It hurts... Can't you be a little gentler? Mother, I'm in pain!" Qian Qiwen was about to get angry, but then he realized what was happening.

Zhang Wanqing also became excited. She stepped forward in surprise. She didn't expect that her son would feel pain after just a few simple strokes from the girl.

"It hurts now? I'm going to break your healed bones and set them back on later. Won't you be in excruciating pain?"

Yu Banxia spoke up, and Zhang Wanqing's eyes widened, clearly startled.

"Do we need to break his leg again?"

“Yes.” Yu Banxia nodded, then explained, “His leg bone didn’t heal properly and it’s completely crooked. Also, it wasn’t treated properly back then, and his meridians are blocked.”

"Young Master Qian has severe blockages in his meridians, which is why he is paralyzed and bedridden."

Zhang Wanqing grabbed Yu Banxia's hand: "Are you really confident you can cure my son? What are the chances?"

"Of course I can cure it! I am the successor of the Thirteen Needles of Taiyi!" Yu Banxia said confidently with a smile.

"What?!" Zhang Wanqing thought she had misheard.

Yu Banxia did not mock the other party, and smiled again, saying, "Don't worry, Mistress. I am the successor of the Thirteen Needles of Taiyi, and I will definitely heal Young Master Qian's leg."

"Oh, young lady, you've got quite the nerve. The Taiyi Thirteen Needles technique has been lost for almost six hundred years. You can't just spout such nonsense." A gentle voice came from behind.

Yu Banxia stood up and looked at the newcomers. The wealthy man, Qian, walked in with a refined and gentle man.

"Husband, is this the official from the Imperial Medical Bureau in the capital?" Zhang Wanqing asked excitedly as she looked at the newcomer.

Yu Banxia raised an eyebrow; she remembered that her senior brother also worked at the Imperial Hospital.

"Yes, this is the renowned Vice President of the Imperial Medical Academy, Jing Zhong—Imperial Physician Jing," the wealthy man said excitedly.

Yu Banxia raised an eyebrow slightly. What a coincidence?

Her senior brother?

"Young lady, you just said you know the Thirteen Needles of Taiyi?" Jing Zhong looked at her gently, without any disdain or mockery in his eyes.

Yu Banxia nodded and asked directly, "Does Madam Qian still need my treatment?"

Zhang Wanqing hesitated, but Jing Zhong laughed: "Hahaha, since we've already invited the young lady here, we shouldn't push her away."

“I can wait a moment. Since I have already promised Lord Zhang to come and treat your son, I will not go back on my word.”

Yu Banxia raised an eyebrow, not expecting that this mistress of the Qian family was from an official family.

That's incredible!

"Then I'll begin." Yu Banxia didn't hesitate and had Yu Mangui turn Qian Qiwen over to his side.

She took out a porcelain bottle, dipped the silver needles in it, then lifted his clothes and inserted a needle into two acupoints on his lower back.

He then pressed the needle flat: "Brother, you can put it down now."

Qian Qiwen felt her soft little hands protecting his waist, and his cheeks flushed.

"Eat it, and you'll fall asleep soon without feeling any pain." Qian Qiwen obediently swallowed the pill.

Before long, he felt his eyelids getting heavy, and then he closed his eyes and fell asleep.

Jing Zhong raised an eyebrow. What a powerful medicine!

"You two should go to the outer room first. Let Lord Jing stay and help you take care of things. As parents, we probably can't bear to see what happens next."

Yu Banxia kindly reminded them, but the couple refused to leave.

Since that's the case, Yu Banxia had no reason to hesitate. Before taking action, she said to her uncle and elder brother, "If the Qian family tries to pounce on me later, you must stop them."

“Okay, don’t worry about the treatment,” Yu Mangui promised Yu Banxia.

Yu Banxia didn't speak. She gathered wood-type supernatural power in her hand, and with a crack, the bone that had already healed broke again.

Just as Zhang Wanqing was about to rush over, she was stopped by the wealthy man.

“We can’t go there. Since we’ve chosen to believe her, we must keep our promise.” The wealthy man hugged his wife, his heart filled with unease.

Zhang Wanqing cried her heart out. Yu Banxia sighed and used her wood-type ability to smash the tiny bones inside into powder.

Then, using wood-based abilities, I carefully repaired the surrounding blood vessels and realigned the bones.

“I have a bone-healing pill that can help him heal quickly, but even at its fastest, it will still take half a month.”

"He must not move around freely for twelve hours after the treatment is completed. He must stay in bed. After twelve hours, he can go out for a walk in a wheelchair."

“I will come to give him acupuncture every two days to speed up his recovery.”

"Bring me a porcelain bowl," Yu Banxia said to the couple, taking out the few remaining regenerative pills she had.

This was developed before my rebirth. In later lives, medicinal herbs are hard to come by, but fortunately, two of them were produced within my space.

If she were a cultivator, the pill would take effect immediately, restoring flesh and bones. Unfortunately, she is not, so the efficacy is naturally greatly reduced.

"Miss, here you go." The servant Ping An handed her the porcelain bowl filled with water.

"Xiaobai, can you put some spiritual spring water in?" Yu Banxia asked Xiaobai.

Xiao Bai replied, "Yes, Master. The ginseng has begun to multiply, and I have more power at my disposal."
