Even the tycoons of wealthy families kneel down; the real heiress is the matriarch.

In less than half a minute, Bai Su had finished writing and showed it to Mrs. Zhang and Zhang Shu.

The two were first puzzled, then shocked, and finally somewhat stunned.

Because Bai Su's prescription was exactly the same as the one written in the medicine bag.

Both of them had carefully examined the prescription, so they could immediately recognize that it was written by Bai Su.

Only Cheng Yizhou looked completely bewildered.

He had absolutely no idea what Bai Su was up to.

But he remembered what Bai Su had reminded him of.

No matter what she says or does, he should not say anything or argue back.

So no matter how curious Cheng Yizhou was, he held back and didn't say anything.

He just quietly ate fruit on the side.

The watermelons from Zhang Shu's house were indeed very crisp and sweet, with his favorite sandy texture.

The only downside is that there are too many watermelon seeds, making it troublesome to spit them out.

He took a tissue, spat the sunflower seeds onto it, and ate them slowly, seemingly unconcerned.

The Zhang couple finally recovered from their shock.

Zhang Shu asked first, "When did you write this prescription? Where did you get it from?"

Bai Su replied, "At that time, you were arranging Aunt Zhang's discharge from the hospital. When I was shaking her hand and talking to her, I took her pulse, and then I made an excuse to go to the Chinese medicine pharmacy to get the medicine. I wrote this prescription myself. I didn't get it from anywhere else."

"..." Mrs. Zhang remembered that Bai Su had indeed held her wrist at that time.

She thought it was just Bai Su showing affection.

"How do you know all this?" Mrs. Zhang asked.

Zhang Shu also stared at her.

Bai Su said, "I don't know if you've ever heard of a name, Bai Tang, a traditional Chinese medicine practitioner."

Zhang Shu shook his head blankly, but Mrs. Zhang said, "I know her; she's a miracle doctor."

Meeting her husband's questioning gaze, she said, "I used to know a woman who ran a foreign trade business. She was a very successful businesswoman who built a large business, but unfortunately, she and her husband never had children."

"Later, she went to the hospital for a checkup and found out that she was infertile. She had taken a lot of medicine but it didn't work. She found that miracle doctor Bai Tang and after three months of treatment, she became pregnant."

"That kid is in college now."

"Later, when Xiaoxiao fell ill, I went to look for her, but she couldn't contact that miracle doctor anymore. I heard that he had gone into seclusion."

Zhang Shu didn't know the legendary doctor Bai Tang, but he remembered that such a thing happened.

My wife did indeed spend some time looking for a miracle doctor.

Just as he was about to speak, Bai Su said, "Bai Tang is my grandmother, my biological grandmother. I've been learning traditional Chinese medicine from her since I was little, and through this exposure, I've indeed learned some skills."

Both of them were surprised.

"Your grandmother is actually the legendary healer Bai Tang?"

"Hmm." Bai Su nodded, took out her phone, and opened a photo: "Take a look, is it her?"

Mrs. Zhang brought her phone over.

She had never met Bai Tang, but the woman who worked in foreign trade had shown her a photo, which made it easier for her to find him.

In the photo, Bai Tang looks much older, and there is a little girl who looks like a primary school student standing next to her.

She looked at Bai Su, then at the person in the photo, confirming that the little girl was indeed Bai Su.

"I never imagined you were the granddaughter of the legendary healer Bai Tang..."

Zhang Shu spoke up, "Why didn't you tell me about this sooner?"

Bai Su said, "Even if I had told you back then, you might not have believed the medicine I prescribed, after all, I'm just a girl who's not even eighteen yet. Now that you've been taking the medicine for a week, you must feel much better, which is why I dared to come and tell you."

"..."

Indeed, as Bai Su said, if they had known at the time that the medicine was prescribed by Bai Su, she might not have drunk it.

It's not that I doubt Bai Su's medicine has any problems, it's just that I feel the prescription the young girl wrote must not be effective, and it would be a waste of time to take it.

Mrs. Zhang and Zhang Shu both looked somewhat embarrassed.

"I'm sorry, Bai Su, it's not that we don't trust you, it's just..."

Bai Su waved her hand to interrupt Zhang Shu: "You don't need to feel embarrassed, it's only natural. If it were me, and a girl under eighteen suddenly offered to prescribe medicine for me, I wouldn't dare drink it either."

Zhang Shu apologized again and earnestly inquired about the situation of his wife.

Bai Su explained Mrs. Zhang's situation in detail.

"It's not a physical problem, it's a mental one..."

The prescription she used only temporarily relieved Mrs. Zhang's anxiety.

"Is it just a temporary relief?" Zhang Shu asked with some regret.

Bai Su nodded and said, "It will relapse soon once the medication is stopped."

"What should we do then?" Zhang Shu asked anxiously.

Bai Su said, "A mental illness requires a mental cure; her inner conflict is the same as your child's illness."

indeed so.

His wife developed these symptoms of frequent tachycardia and difficulty breathing only after their son fell ill.

"I told you before that I could take a look at your son's illness, but you just thought I was joking. Now, I'm asking you again, do you need my help?"

The couple exchanged a glance and nodded simultaneously.

"need!"

Where is he?

"It's in the bedroom..." Mrs. Zhang hurriedly led Bai Su inside.

Bai Su examined the area and frowned slightly.

"It's a bit troublesome, but it's not impossible." She wrote out a prescription for her son to take the medicine for the time being.

"After completing three courses of treatment, I will proceed to the next step."

One week is one course of treatment, and it takes at least three weeks.

Mrs. Zhang nodded repeatedly: "I'll go get the medicine right away."

"Go."

Bai Su did not stop her.

Because she still had something to say to Zhang Shu.

After Mrs. Zhang left with her driver, Zhang Shu said, "I really don't know how to thank you enough."

Whether their son's illness can be cured is another matter, but it's true that his wife has been in much better spirits this past week.

For this reason alone, he should thank Bai Su.

Bai Su glanced at Cheng Yizhou, who was still eating watermelon, and said, "To be honest, I do have something I need your help with."

"You said that as long as I can do it... even if I can't, I will find a way to ask someone to do it."

Bai Su said, "It's very simple, you can handle it yourself. I want to transfer my spot in the Mathematical Olympiad to Cheng Yizhou."

Zhang Shu frowned slightly.

Cheng Yizhou suddenly looked up.

So, Bai Su brought him here for this reason?

Zhang Shu cleared his throat and said, "Your teacher, Ms. Chai, mentioned this to me, but I don't think it's appropriate... What do you think, Cheng?"

Students from No. 3 Middle School have never achieved any good results in this competition.

Bai Su is the most promising candidate.

Zhang Shuxin did not agree with giving the spot to Cheng Yizhou.

But I was too embarrassed to refuse outright.

After all, Bai Su had helped his wife and son get medical treatment, and that was why he came to their door.

"I don't need this spot; I wouldn't win an award anyway," Cheng Yizhou said with a dark expression.

"You can do it. Believe in yourself, and believe in me."

"This isn't a matter of believing or not..."

He has self-awareness.

He knew how difficult this competition was, even if he hadn't studied before.

"If you participated yourself, you'd definitely get a good ranking, why give it to me?"

Bai Su said, "Because I don't need to rely on the college entrance examination to get into God University."

"Are you giving me charity?"

Bai Su frowned: "I'm just helping you. Why call it charity between family members?"

The words "family" reminded Cheng Yizhou of Bai Su's current identity.

She was his ancestor.

At best, it can only be described as taking care of the younger generation.

But he didn't want it to be like this.

He could work hard for any extra spots, but he couldn't bring himself to steal Bai Su's.

He still has some sense of shame.

Grandpa wouldn't agree if he found out; he'd give him a good scolding.

Zhang Shu, who was listening nearby, was completely confused.

What does it mean to be a family?

"..." Cheng Yizhou didn't know how to explain.

Bai Su said, "His grandfather and my grandmother were classmates, and I often visit the Cheng family."

"So that's how it is."

No wonder Bai Su was willing to give up her spot to Cheng Yizhou.

Based on this relationship, they can indeed be considered a family.

In Master Cheng's time, fellow apprentices were no different from blood brothers.

"Can you help with this?" Bai Su asked again.

Cheng Yizhou wanted to say something, but Bai Su glared at him and shut him up.

"Don't forget what I told you in the car."

No matter what she says, he should not refute it.

Cheng Yizhou clenched his fist and remained silent, but the watermelon in his hand suddenly seemed to lose its sweetness.

"Principal Zhang?" Bai Su turned her gaze to Zhang Shu again.

Zhang Shu said with some difficulty, "This matter is not something I can decide alone; the entire math group needs to discuss it in a meeting. Unless they all agree, if I force it on Cheng Yizhou, it might have a lot of negative impact on him."

Cheng Yizhou was a troublemaker who always skipped classes.

Moreover, everyone knows that Cheng Yizhou comes from a well-off family.

Once this quota is set, rumors and gossip are inevitable.

"He's not afraid," Bai Su said. "Please help me."

Cheng Yizhou: "..."

He wasn't afraid of gossip, but he didn't want to take what rightfully belonged to Bai Su.

Principal Zhang was silent for two seconds, then agreed.

"I will discuss this with them on Monday."

"Thank you for your help."

Bai Su didn't linger and left with Cheng Yizhou.

Before leaving, she reminded Zhang Shu to make sure his son took his medicine on time.

As for his wife, once his son recovered, she was cured as well.

However, if you want to maintain a good night's sleep during this period, continue taking the same prescription as before.

After leaving the Zhang family's house, the two got into the car.

She asked Lao Ding to drive to Sun Yuze's company.

Cheng Yizhou remained silent.

Bai Su smiled and said, "What? Are you scared? Afraid people will say you're 'unworthy of your position,' afraid you won't get a good ranking?"

Cheng Yizhou remained silent.

He is not afraid of the former; he is least afraid of what others say about him.

He doesn't care.

The latter... does exist.

But more than anything, she didn't want to take Bai Su's things away, and she didn't want to rely on Bai Su's help for even these things.

Otherwise, his status in front of Bai Su will only be more like that of a junior.

But... Bai Su has already gone to such lengths for him. If he were to back down now, he wouldn't even be a man, let alone a junior.

He was silent for a moment, then asked, "Could you help me catch up on my studies during this time?"

Bai Su raised an eyebrow: "Okay, first call me 'Ancestor' so I can hear it."
