The richest man's parents were kidnapped, and his adorable son captivated the entire family.

"We should see him off." The principal continued to follow Gu Shiyu out.

Inside the campus, the principal stood bowing beside a young man named Gu Shiyu, which looked rather odd.

The principal escorted him to the car at the door and watched it drive away before turning around.

As they passed the security office, the principal pointed in the direction Gu Shiyu had gone and asked, "Did you see what that boy looked like?"

The security guard nodded.

"Remember this well. If you see him again, be sure to treat him well!" the principal instructed.

"Okay, I got it." The security guard tucked his palm into the seam of his pants, his attitude positive and helpful.

Satisfied with his response, the principal entered the campus with peace of mind.

Research Institute.

"Teacher Xie?"

The students were surprised to see Xie Beiling appear.

He hasn't been to the research institute for half a month since Xie Yumin woke up and left.

"Xiao Zhang, take these two documents and have a paternity test done." Xie Beiling took Tian Tian's hair and Ruolan's hair.

The student glanced at the sealed bag in his hand, took it immediately, and said, "Okay, teacher, I'll go right now."

"Wait a minute." Xie Beiling called out to him as he turned around, "Give it to me, I can do it myself."

This was something Gu Yinshen had entrusted to him, and to ensure the final result was foolproof, he decided to come in person.

Sweetie's existence is not only important to the Gu family, but it also determines Mengmeng's future life in the Gu family.

He was at the Gu family home that day and clearly felt Tian Tian bullying Meng Meng. If it's this unfriendly at the very beginning, who knows what she might do in the future.

For Mengmeng's sake, he had to thoroughly investigate whether Tiantian was indeed the Gu family's lost daughter.

Holding a sealed bag, Xie Beiling stormed into the research lab.

……

Master Ziyang sat cross-legged inside the cave, his hands placed in front of his chest as he regulated his breathing.

After a moment, he burst into laughter, "Good stuff, really good stuff."

After eating the divine flower that Tian Tian received from Meng Meng, the wound on his chest was instantly healed, and his spirit was also enhanced.

After his last battle with Bi Fang, Bi Fang was also seriously injured, making this the perfect opportunity for him to strike.

Master Ziyang glanced at the sky outside the cave; school should have let out by now.

He stood up, dusted himself off, and strolled out of the cave. With a leap, he soared into the air.

……

"Mengmeng, are you all packed?" Tangtang stood obediently next to Mengmeng's desk, carrying her little schoolbag.

Mengmeng zipped up her backpack and said shyly, "Tangtang, I'm going home with Sister Tiantian today. Do you want to come with us?"

She knew that Tangtang didn't like Tiantian, so she didn't force her to leave the school with her.

Tangtang was a little conflicted, but when she saw Tiantian walking towards her with a serious expression, one hand hooking her schoolbag, she shook her head and said, "Then I'll go by myself today."

After saying that, Tangtang quickly turned and left. She was afraid of Tiantian and didn't want any contact with her.

Mengmeng opened her mouth wide, then reluctantly closed it.

"Let's go." Sweetie said casually as she passed Mengmeng's desk, without stopping to wait for her.

The person had already gone far away. Mengmeng hurriedly got out of her seat and ran after them with her little schoolbag on her back.

"Sister Sweetie, wait for Mengmeng!" Mengmeng called out anxiously as the distance between them grew larger.

They said they would leave together, but Tian Tian never intended to wait for Meng Meng and walk intimately side by side with her.

After running all the way, Mengmeng was panting heavily when she arrived at the school gate, and her little face was flushed.

The security guard recognized Mengmeng; he knew that the younger sister of the boy whom the principal had instructed to take special care of that morning was Tiantian.

"Little girl," the security guard bent down and stopped Mengmeng, "slow down, don't fall."

"Thank you, Uncle. Mengmeng was very careful," Mengmeng replied with a smile.

"Being careful isn't an option either. There are so many people leaving school right now. If you get jostled or bumped into, it'll hurt a lot. Be good, we'll walk slowly from now on, no rush," the security guard gently advised Mengmeng.

Mengmeng could see the security guard's affection for her, so she nodded and sincerely replied, "Okay, I'll remember what you said, Uncle."

Her confident assurance amused the security guard. He couldn't help but pat Mengmeng's hair, "Let's see if your parents are here."

"Mengmeng will go back with her sister." After saying that, Mengmeng looked around for Tiantian's figure in the crowd.

In just a short while, Sweetie disappeared without a trace.

When Mengmeng couldn't find her, she became anxious. "Where's my sister? She was just here!"

"Son, why don't you call your parents and have them come pick you up?" the security guard said.

These are all wealthy and powerful people; if something goes wrong at the school gate, a mere security guard like him can't afford to take responsibility.

The security guard had already taken out his phone. "Son, do you know your parents' phone numbers?"

Mengmeng shook her head. "No, Mengmeng promised her sister that she would go home with her. If she calls Mom and Dad, she will break her promise. That won't do, it's not good."

"How could that be? You've gotten separated from your sister, of course you should call your parents. Otherwise, they'll be worried if they can't find you, won't they?" The security guard squatted down and patiently explained.

Just as she was hesitating, the image of Tian Tian giving her serious instructions flashed into her mind.

Mengmeng, you have to come home with me today! Don't stand me up again, you hear me?

"Uncle, no need. Mengmeng will look for her sister again. She should be waiting for Mengmeng by the roadside."

The small figure darted away in the blink of an eye. The security guard wanted to chase after him and take him to the security room, but it was a busy time after school, and once he left, there was no one watching over the school gate.

Tang Yibai looked at Mengmeng, who was searching for something in the crowd, and asked Tangtang beside him, "Baby, why didn't you come out with Mengmeng today?"

“Mengmeng is going back with her sister, and I… I’m a little scared of her sister…” Tangtang said softly, counting on her fingers.

A cute older sister?

Tang Yibai had met her brothers, but he had never heard anything about her sister from Tang Tang.

"Why? Doesn't her sister like our Tangtang?" Tang Yibai asked, a pang of pain in his heart.

This was the first time Tangtang had told him about her fear.

Tangtang shook her head; she didn't know how to explain.

"It's because..." Tang Yibai glanced at Tang Tang's missing finger, hesitated for a moment, but didn't ask.

"Dad, Mengmeng's older sister is very fierce. She's also fierce towards Mengmeng and bullies her at school," Tangtang said.

"Bullyed?" Tang Yibai asked in shock. "Really? Didn't Mengmeng tell their parents?"

Tangtang shook her head. "Her older sister just returned home. Mengmeng really wants to get close to her sister, but her sister seems unwilling and doesn't like her very much."

Mengmeng didn't explain these things to Tangtang in detail, but Tangtang could sense it through their interactions at school.

In the next classroom, there are two sisters who hold hands and play and do things together every day. Mengmeng and Tiantian have never played together. Even when Mengmeng tries to play with her, Tiantian always refuses. So Tangtang can tell that Tiantian doesn't like Mengmeng.

Hearing this, Tang Yibai sighed, "Mengmeng is such a good child, how could anyone not like her?"

Tangtang didn't understand either.

Mengmeng tried so hard to become close sisters with Tiantian, but she didn't appreciate it at all. If it were her, she would definitely work overtime to be good to Mengmeng.

Tang Yibai remembered seeing Mengmeng frantically searching for something and became worried. "Did she and her sister leave school together?"

"Yes, Dad."

"broken!"

Tang Yibai slapped his thigh, hoping that his worries were unnecessary.

"Dad, what's wrong?" Tang Tang asked worriedly, holding Tang Yibai's hand.

He suddenly slapped his thigh, startling Tangtang.

"Tangtang, quickly see if you can find Mengmeng. I suspect her sister doesn't intend to go back with her." Tang Yibai told Tangtang his guess.

If Tang Tang hadn't told him that, he wouldn't have thought about it in that way.

Tangtang was worried about Mengmeng and immediately started searching for her in the crowd.

"Mengmeng, come here!"

Across the street, Tian Tian beckoned to her with one hand across her chest, as if calling a puppy.

"Okay, sister, Mengmeng is coming right now." Mengmeng looked back and forth between the two sides, then quickly crossed the middle of the road and walked towards Tiantian on the other side.

Sweetie looked at both sides of the road, hoping that a car would pass by quickly, preferably blind and unable to see Mengmeng crossing the road, and would hit her hard.

Unfortunately, even though Mengmeng had already arrived beside her, no cars were seen speeding by.

Sweetie looked at Mengmeng, who was smiling at her, with disappointment, and said coldly, "Let's go!"

"Sister," Mengmeng looked at the school gate, "Isn't the driver coming?"

The school is far from the Gu residence, and it takes fifteen minutes to get to school by car every day.

Sweetie glared fiercely at Mengmeng, "Didn't you promise to go home with me? Are you going to go back on your word now?"

"No, no." Mengmeng waved her hands in front of her in a panic, not wanting Tiantian to misunderstand and get angry. "Sister, I'll go with you."

Sweetie turned around and walked ahead.

Mengmeng followed obediently behind, not daring to ask or say a word.

Tangtang, who was still at the school gate, saw Mengmeng and Tiantian walking one after the other across the road. She felt scared and dared not go forward to chase after them.

"Tangtang, have you found it?"

"Dad, have they already left?"

"gone?"

Tangtang nodded.

Seeing that Tang Tang's expression was not good, Tang Yibai gave up looking for Mengmeng. "Since they've left, then it's alright. Let's go back too."

After walking a short distance, Mengmeng's back was covered in sweat. Looking at Tiantian, who was still walking, she didn't dare to slow down.

"I'm thirsty." Sweetie suddenly stopped and turned to Mengmeng.

Mengmeng was actually thirsty too.

However, neither of them had a water bottle in their schoolbag.

"Sister, Mengmeng has no money."

"I have."

Sweetie took a hundred-yuan bill out of her pocket and threw it in front of Mengmeng.

Before they could even react, the money floated lightly in the wind, twirling a few times in the air before falling to the ground.

Mengmeng quickly squatted down and picked it up from the ground.

"Let's go buy it." Sweetie sat down on the edge of the flower bed next to them.

The surrounding area is very open; you can't see any convenience stores or shopping malls at a glance.

"Sister, where is Mengmeng going to buy water?" Mengmeng asked sincerely.

Sweetie rolled her eyes so hard they almost popped out of her head when she heard her question. "You're asking me? Who am I supposed to ask? If I tell you to go buy it, then hurry up and go find a store to buy it. Stop talking so much!"

Mengmeng was very sad. She didn't understand why her sister was so mean to her when she was trying to communicate with her seriously.

"What are you still standing here for? Hurry up and go! Do you want me to die of thirst?" Sweetie roared.

Mengmeng quickly took action.

She felt wronged, but in order not to upset Tian Tian or Ruolan's mother, she could only force herself to endure her exhaustion and helplessness and aimlessly search for a store.

Little did she know that as soon as she left, Tian Tian turned around and headed towards the school.

Nearly half an hour had passed since school ended, and Gu Shiyu sat in the car, but Mengmeng was nowhere to be seen.

Knock knock~

The driver was banging on the car window.

Where's Mengmeng?

"Young Master, Miss Mengmeng has already left and returned home."

"gone back?"

Gu Shiyu was surprised.

He personally picks Mengmeng up from school every day; if he doesn't come, he arranges for someone else to do so. But this morning he promised to come personally after school, so Mengmeng shouldn't have gone home first.

Something must have happened!

He took out his phone and dialed the landline at home.

The phone rang for a long time before it was finally answered.

Has Mengmeng gotten home yet?

"Young Master Shi Yu?"

Aunt Ping answered the phone.

"Aunt Ping, is Mengmeng home?"

"She's not here. She hasn't come home from school yet," Aunt Ping said, glancing at the time. "School's already over. Aren't you all together?"

"Beep beep..."

She was met with a busy signal that the phone had been disconnected.

Aunt Ping felt inexplicably uneasy.

"Did something happen?"

Her whispered murmur was overheard by Aunt Xue, who was passing by. "What's wrong? What happened?"

"Young Master Shi just answered the phone to ask if Mengmeng had come home."

"Wait a minute, Mengmeng should be back by now."

"Yeah, my heart's pounding, I feel like something's going to happen. Do you think Mengmeng might...?"

Aunt Ping stopped mid-sentence, not daring to continue.

Seeing Gu Shiyu hang up the phone and get out of the car, the driver quickly followed behind.

The security guards in the security room perked up and came out as soon as they saw Gu Shiyu.

"Have you seen this child?" Gu Shiyu took out his phone, and the screen showed a cute picture of Mengmeng.

"I saw her. I even said a few words to her after school, reminding her to walk slowly and not run," the security guard said.

Upon hearing this, Gu Shiyu immediately became excited, "Did you see who she left with?"

"She said she was looking for her sister, but I didn't see her sister, and she just ran away," the security guard recalled.
