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

Upon hearing that he could help Bai Su with something, Cheng Sihai immediately perked up.

He wasn't afraid of Bai Su asking him to do things; he was only afraid that there was nothing he could do for her.

"Please tell me! Just give the order, and I'll go through fire and water without hesitation!"

"You don't need to climb mountains of knives. With your physique, you couldn't even climb that little scenic mountain up ahead."

"Master, really! I'm not that weak! But Master, what do you need me to do?"

Distracted by Cheng Sihai, Bai Su almost forgot about the important matter.

"Go and investigate Du Moli for me."

"Is that the founder of the Du Group?"

"Um."

"I remember you used to be roommates with her, but you two didn't seem to get along very well. What happened? Did she offend you?"

"No...it's just that I feel like something's not quite right. Could you investigate her for me first? From...after I passed away until now, what has she done? Inquire as thoroughly as you can. Also, while you're at it, investigate her granddaughter."

"Yes! I'll take care of it myself!"

"Remember, don't alert the enemy."

"clear!"

Bai Su returned to the sofa, picked up her black tea, and took a sip.

The moment she saw Du Moli's granddaughter on the news, she had a very strange feeling. She couldn't explain it, but it just felt very strange.

She initially thought she was overthinking things, but after returning to the research institute, this feeling became increasingly strong.

Originally, she wanted Pei Yuanshan to investigate, since he was more reliable than Xiao Si.

But considering that Xiaoshanzi's health had not fully recovered, she decided to let Cheng Sihai handle it.

Although Cheng Sihai is usually unreliable, he will always do his best to do anything she asks him to do.

As for why they didn't approach Pei Wenyan, it was because Pei Wenyan knew very little about Du Moli, far less than people of their generation who had worked together.

Cheng Sihai and his group knew even better how to investigate Du Moli.

Time flew by and it was five o'clock.

Shortly after five o'clock, Bai Su received a call from Cheng Yizhou.

"Ancestor..."

The reason he would call her that is because there is no one around.

Bai Su then asked directly, "Were the questions difficult this time? Did you solve them all? Are you confident of getting into the top fifty?"

Three questions were asked in a row.

Cheng Yizhou answered them one by one.

"The questions were very difficult this time. When I came out, I heard a senior who had repeated a year and participated in the competition for the second time say that the difficulty this time was much higher than last year."

"I can do most of them, but there are two I just can't..."

"I simply left those two questions blank, using them to check the questions I did, to ensure a 100% accuracy rate."

"As for whether I'm confident about making the top 50... I'm not so sure yet. I don't know the level of the other candidates; they all come from different schools, and there are candidates from all over the country, so... I can't answer you."

Bai Su said, "It's already pretty good that you only missed two questions. Now that the exam is over, don't dwell on it. Pick a restaurant to celebrate your successful exam."

Cheng Yizhou asked somewhat embarrassedly, "Are we celebrating before the results are even out?"

"Of course! You haven't had a proper rest these past few days because of preparing for the exams, so now that they're over, shouldn't you celebrate and say things will be easier from now on?"

"Where shall we eat?"

"You pick a restaurant, and I'll take your grandfather there. I'll also invite Qi Yu."

"Okay. I'll send you the restaurant information in a bit."

"Um."

Just as the call ended, Cheng Sihai came over to ask her what she wanted for dinner.

Bai Su said, "Let's go out to eat and celebrate."

"What are we celebrating?"

Bai Su looked at Cheng Sihai: "Yizhou participated in the Imperial University's Mathematical Olympiad, didn't you know?"

"He hasn't been home lately, so I don't know much about his situation..."

His attention was entirely on his master.

Bai Su briefly explained the prestige of the International Mathematical Olympiad to him, and Cheng Sihai's eyes widened.

"Can this kid...do he handle it?"

"You don't believe in his talent, and you don't believe in my teaching techniques either."

"I believe you! How could I not believe in my master? Hehe..."

Just then, Cheng Yizhou sent over the restaurant information, so Bai Su and Cheng Sihai set off for the restaurant together.

On the way, Bai Sulian tied up Fu Qiyu.

Fu Qiyu is on duty today and is just getting ready to pack his schoolbag.

"I was just about to come find you..."

"Then don't wander off. Wait for me at the school gate, I'll come pick you up."

"it is good."

Fu Qiyu hung up the phone, a gentle smile blooming on his usually cold face.

Only Bai Su could make him happy so easily.

Just then, Ye Yixue came in from outside the classroom.

She wasn't on duty, but she was a sanitation inspector.

As soon as she entered the classroom, she saw Fu Qiyu smiling, which was unusual for him. She didn't know what he was smiling about, but it was clear that he was in a very good mood.

Should we take this opportunity to discuss our previous topic with him again—their common enemy, Bai Su?

Just as Ye Yixue was about to take the opportunity to have a good talk with Fu Qiyu, her phone vibrated in her pocket.

She took out her phone and saw that it was Ye Xiaofeng calling.

Fu Qiyu had already packed his schoolbag and bypassed her, leaving through the front door.

Ye Yixue had no choice but to give up and answered Ye Xiaofeng's call.

"dad……"

"Take the money now and go to the Maple Leaf Road Police Station to get your mother released on bail."

Ye Yixue was stunned. For a moment, she wondered if there was something wrong with her ears.

"W-what did you say...?"

"I asked you to get your mother released on bail... She caused trouble at the Pei Group today, and the Pei Group called the police, who took her away. I was on a business trip abroad and only found out about this after my plane landed. You need to go there for me right away."

As he spoke, he cursed and swore that Dong Suying was brainless and had disgraced him.

"Even if you're going to cause trouble, you can't do it at the company. Wouldn't that just be handing them leverage?"

"What a stupid woman!"

"How could I have married such a completely useless and stupid woman!"

Ye Xiaofeng deeply regretted his actions.

But he forgot that Ye's Group was just a small company back then. He only managed to grow Ye's business by marrying Dong Suying and using the dowry given by her ex-husband.

As time passed, he deliberately ignored those memories, and they were altered to make it seem like "the Ye Group was built by him alone."

Ye Yixue's eyes gradually darkened.

The couple seems to be getting increasingly estranged...

Loving couples are never like this; she had a vague premonition that they might get divorced.

If they divorce, who will she belong to?

Gui Dong Suying?

She absolutely refuses!

Dong Suying is a good-for-nothing who only knows how to spend money; there's absolutely no future in following her.

She needs to cling tightly to Ye Xiaofeng's leg.

"Mom really did something wrong this time. Dad, you can go on your business trip without worry. I'll handle things here."

"Thank goodness you're here. Go ahead, and remember to warn her not to cause any more trouble. We'll talk about everything after I get back to China."

Ye Yixue could detect a hint of gritted teeth in Ye Xiaofeng's voice.

"Yes, Dad."

Ye Yixue hung up the phone, a thought flashing in her eyes, but she quickly suppressed it.

That's too risky, let's forget about it.

Let's take a step by step.

Besides... they're both this age, they've been making do with each other, it shouldn't come to the point of divorce.

She should try to keep Dong Suying calm and prevent her from going on a rampage.

Ye Yixue hurriedly ran down the teaching building.

Before long, she caught a glimpse of Fu Qiyu standing not far ahead.

Is he waiting for a bus?

Just as he was about to step forward, he saw Bai Su get out of a luxury van and walk quickly toward Fu Qiyu.

Fu Qiyu naturally took Bai Su's hand.

Bai Su said something, and Fu Qiyu's face showed the same smile that Ye Yixue had seen in the classroom.

"boom--!"

In an instant, Ye Yixue felt as if she had been struck by lightning.

Her conversation with Fu Qiyu last time was replaying in her mind.

Fu Qiyu, I don't understand, what did I do to offend you...?

Because you are Bai Su's sister.

He disliked her because she was Bai Su's younger sister.

It wasn't because he disliked Bai Su, but simply... because she and Bai Su hated each other.

He... actually likes Bai Su, which is why he hates his younger sister.

But she mistakenly thought that he disliked Bai Su, and therefore disliked her, his younger sister, as well.

No wonder!

No wonder when she said she also hated Bai Su, he told her to get lost and never appear in front of him again.

However, she thought that she hadn't said enough and wanted to continue to speak ill of Bai Su in front of Fu Qiyu.

She never understood the meaning of Fu Qiyu's sentence, "Because you are Bai Su's sister."

I see, I see!

In an instant, embarrassment, regret, anger, and hatred all came together, causing her to tremble uncontrollably.

She wished she could rush up right now and strangle Bai Su to death!

Her life was peaceful, happy, and full of hope.

It's all because of Bai Su's appearance that her life is now a complete mess!

Even his previously proudest academic performance has now declined sharply!

It also made her unable to stand up straight in front of Fu Qiyu.

—If Bai Su hadn't spoken ill of her to Fu Qiyu, how could Fu Qiyu have treated her like this?

At this moment, her disgust for Bai Su reached an almost unbearable level.

The instigator, however, smiled broadly and, hand in hand with Fu Qiyu, got into a luxury van, which sped away.

Ye Yixue ran over quickly, staring intently at the car, so engrossed that she didn't even notice her fingernails digging into her palms.

"Ye Yixue? What's wrong?"

The homeroom teacher happened to be driving at the intersection.

Ye Yixue suddenly snapped out of her daze and managed a weak smile.

"I'm fine, teacher."

"You need to adjust your mindset. The college entrance exam is just around the corner, and you can't afford to keep falling behind. Your teacher hopes you can return to your previous level in the next mock exam..."

The homeroom teacher patiently guided the students and said a lot.

But Ye Yixue didn't hear a single word.

Her mind was in complete chaos.

The homeroom teacher quickly noticed that Ye Yixue was distracted.

She sighed, rolled up the car window, and drove away.

The students themselves had given up on themselves, and as a teacher, there was nothing she could do.
