The male supporting character was actually myself.

"Brother is the best!" As soon as the youngest Zhou Ruofeng entered the room, she saw a room full of fluffy, soft, and cute dolls. Her dirty and tattered little doll had been washed, repaired, and placed on the bed. She threw herself onto the soft and comfortable bed and buried herself in the plush toys.

Bai Wei's eyes lit up with excitement as she looked at the wall full of traditional Chinese medicine books in the small study partitioned off next to the bedroom!

Wang Mengtian's room was decorated in a dreamy and gorgeous style, fulfilling all her fantasies and instantly filling her empty heart.

Ye Zhi Qiu and Lin Yan Ran liked the activity room on the basement floor the most, as it was very convenient for them to exercise and practice martial arts.

"Starting today, everyone will participate in a basic etiquette course." After they finished their excitement, Jiang Chen clapped his hands and reminded them, "After completing the basic course, anyone who wants to continue learning can tell me."

Since everyone's academic level is uneven, I've hired a private tutor to provide you with targeted supplementary lessons.

As for money, your brother will find a way to earn it, so you don't need to worry about it at any time.

What you need to do is calm down, reflect, think about the path you want to take in the future, and start working hard now.

I will provide you with the best living conditions, and now I want to see changes in you.

Confident, generous, self-loving, friendly and harmonious with her sisters, and with a clear vision for her future.

Did you all understand?

"Understood!" the seven younger sisters answered in unison.

Perhaps they had been a little rebellious before, and not worried about being sent back to the orphanage, but now all the little girls had only one thought—listening to their brother was the right thing to do!

People will weigh the pros and cons.

As long as you meet your brother's requirements, you can stay in the luxurious castle and live a happy life like a princess. Who would want to go back to the orphanage and live a hard life?

What's more, her brother gives so much yet asks for so little.

"Xiaobai, fully charge our recording equipment and start monitoring every corner of the entire manor." Jiang Chen watched his seven younger sisters excitedly moving around the spacious villa and whispered, "There will definitely be various adjustments at the beginning. I'll make an example of anyone who dares to run into trouble."

"Alright!" The little white cat stroked its big ears, wagged its tail, and hummed a song. It quickly adjusted the props and took in all the corners.

For the next period of time, Jiang Chen and the girls engaged in a battle of wits.

After causing trouble for the nth time and being punished by her brother, Lin Yanran, Wang Mengtian, and Leng Yueshuang gathered in their little sister Zhou Ruofeng's room and strongly demanded that their little sister, who had already demonstrated her computer genius, help them decipher the security cameras in the manor villa, so that their brother wouldn't always catch them red-handed.

"I think it's because my brother is too amazing!" Zhou Ruofeng was in a familiar environment and talking to familiar people, so she was very natural. She looked troubled and said helplessly, "Last time I tried to hack the traffic camera system, but I still couldn't crack the surveillance system that my brother installed."

I couldn't even find the camera at the angle where my brother released the ultra-high-definition video.

It seems I need to study harder!

With a cold expression, Leng Yueshuang patted her shoulder encouragingly, "Keep going! I believe you can succeed!"

"Tonight I'm going to try and 'assassinate' my brother again!" Lin Yanran rubbed her fists together, full of fighting spirit. "I refuse to believe I can't beat my brother!"

The stylishly dressed Wang Mengtian shrugged and shook her head, saying, "The fighting and killing can only be left to my third sister and sixth sister. I still have to go to my music class. My brother said that when my second sister turns eighteen and can register a company, he will let you set up an entertainment and film company. Then I can fulfill my dream of becoming a big star!"

“Then you’d better study hard.” Leng Yueshuang gave her a critical look. “I have high standards for business. If you don’t have the ability to make money for the company, even if you’re my sister, it won’t work.”

"Just wait and see, I will definitely become a triple-threat superstar in film, television, and music!" She proudly walked out of the room with her princess dress in her hand to go to class.

Lin Yanran, full of ambition, was about to drag her third sister to practice martial arts again;

After they all left, Leng Yueshuang whispered in Zhou Ruofeng's ear, "The app you made has a good future. I've already started promoting it heavily. I'll share the profits with you when we make some money."

“Just leave it with my second sister.” Zhou Ruotong shrugged and whispered as she typed on the keyboard, “I’m not short of money. If my brother hadn’t prepared everything for me, I’d probably have nowhere to spend my allowance, and I probably would have tried to hack into the bank system long ago…”

"Shh!" Leng Yueshuang quickly covered her mouth. "You can think about it and do it, but you can't talk about it!"

Zhou Ruotong frowned slightly, "I didn't intend to do it either."

"boom!"

As the two were talking, an explosion came from the backyard.

Bai Wei, who was in the next room, put down her medical books, acupuncture needles and medicinal herbs, and hurriedly picked up her small medicine box and ran to the backyard. "It must be that my older sister blew up the lab again while doing an experiment. I hope she wasn't hurt this time!"

Ye Zhi Qiu reacted the fastest and acted the most decisively. Before her brother and sisters arrived, she had already rushed into the messy laboratory and carried out her eldest sister, whose face was covered in soot.

"I'm sorry, the dosage of the experimental sample was probably a bit inaccurate. This is the fourth time the research and development has failed." Xiang Ninghua sat on the floor, writing and calculating diligently, silently waiting for her assistants to put out the fire and reorganize the laboratory.

Jiang Chen couldn't help but facepalm. "Could you research something like artificial intelligence, something that won't explode? Isn't it a bit too dangerous for a girl to do these things?"

"I'm collaborating with my younger sister on artificial intelligence development; I'm responsible for the body parts. What happened just now was an accident. Actually, the most crucial issue is the battery. I envision it being lightweight, stable, and long-lasting, ideally a miniature nuclear fusion reactor..."

The little white cat's eyes rolled and black circles appeared on its head. "Host, I think this place can't hold your little sister anymore. Let's build her a professional laboratory, so she doesn't blow us up one day."

Chapter Twelve: The Promise of Childhood Sweethearts

Looking at the messy small laboratory with a worried expression, and then at her other younger sisters who were already used to it, Liu Qingmei whispered in Jiang Chen's ear, "Ninghua is only a sophomore in high school. Is it really okay for her to do this kind of experiment?"

"Don't worry, she's very sensible." He patted Qingmei's shoulder to comfort her, "Among all our sisters, she's the most reliable when it comes to getting things done."

Liu Qingmei: ...

But thinking about it carefully, it seems to make sense. These girls are all incredibly beautiful and intelligent, each with their own strengths and talents, and they all have some personality issues.

As the eldest sister, Xiang Ninghua is truly the most reliable one when she's not conducting experiments.

"Brother, am I too stupid?" Xiang Ninghua looked at the laboratory after writing and calculating, a trace of guilt appearing on her face. "Not only did I spend a lot of money, but I also always caused you trouble."

Jiang Chen encouraged her sincerely, "What kind of scientific research doesn't involve experiments? Experiments are about learning from failures. You're only in your second year of high school and you've already started researching artificial intelligence projects. That's already very impressive."

Keep going! I believe you can do it!

This afternoon I'll arrange for someone to build a specialized lab for you. You can work on other things first; we can continue with things like nuclear fusion and nuclear fission after we move to the new lab.

He turned around and saw Zhou Ruofeng, and realized that the time was almost ripe.

Therefore, I specifically instructed her to build two websites.

A private diary space exclusively for the eight siblings;

The other one was only for himself and Liu Qingmei.

He plans to write down all the days he spent with his sisters in a diary on his diary website, starting from the first day he met them.

Each of the eight people has their own login account and password, and can choose to record secrets or write a diary, with functions such as public, anonymous, and hidden.

"Brother, that's a great idea!" Zhou Ruofeng clapped his hands happily. "I'll go design and build the website right away! Many years later, we'll look back at those records of the past together, and that will definitely be a lot of fun!"

Wang Mengtian's eyes lit up, "It should be able to upload photos! I want to upload all my beautiful photos!"

"It would be even better if it supported voice input and video, so I could share my experimental progress in public areas."

"It would be even better if it had a budgeting feature!"

"Huh? Why am I not listed on your website?"

"We're the younger sisters, and you're the sister-in-law! You should definitely share the secret contact point with my brother!"

"You little brat, you're talking nonsense again!"

……

The younger sisters chattered around Liu Qingmei, discussing the website construction. Jiang Chen's lips curled up slightly. "Xiao Bai, the protagonist definitely won't have any memories of you after he transmigrates."

So, once the website is built, don't tell me your registered account and password.

Just log me in whenever I need to.

The little white cat's eyes lit up immediately, and it patted its fluffy little paws in delight, saying, "As expected of the host I chose, you are so clever! The protagonist can't log in without an account and password, so naturally he can't write in his diary. The sisters will definitely notice something is wrong!"

Zhou Ruofeng quickly established two websites with the highest security ratings.

At this point, there are only ten days left until the college entrance examination.

The library was at a comfortable temperature, and the bright sunlight streaming in through the windows cast a dazzling glow on the white curtains, making the white-shirted boy leaning against the windowsill reading appear to glow slightly as well.

Liu Qingmei rested her chin on her left hand and held a pen in her right, gazing intently at that perfect profile, feeling she couldn't get enough of looking at it.

Noticing the other person's gaze, Jiang Chen slightly raised her head to meet her beautiful, bright eyes.

The two smiled at each other, and the shimmering light seemed to dim, filling the air with the vibrant energy of youth.

"The college entrance exam is just around the corner. Are you really sure about this?" Liu Qingmei hesitated for a moment, unable to put pen to paper, and said softly, "Are you really willing to give up your future and not even go to university for your sisters who are not related to you by blood?"

Jiang Chen smiled and shook his head, saying, "A degree is just a piece of paper to me; it's useless. Besides, I have more important things to do. Perhaps you can find the answer on our website in five or six years."

Before we receive the letter we promised, I hope you can enjoy your youth to study and pursue your dreams.

Have you decided what you want to study?

"I want to study psychology and become a psychologist in the future." Liu Qingmei said with a slight upturn of her lips, "You have seven younger sisters, after all. In the future, I will have to deal with seven beautiful and smart sisters-in-law. I need to have some real skills to protect myself."

"So, you, my sister-in-law, want to study psychology to outsmart them?"

Liu Qingmei smiled smugly, "No way! I studied psychology to deal with you, of course. Even though I have seven formidable sisters, as long as I have you under my control, they'll all be obedient, won't they?"

Jiang Chen raised an eyebrow slightly upon hearing this. "A clever idea! It's just a pity that I can't give you any promises right now. I'm not even sure if that matter can be resolved smoothly myself."

"Does it have anything to do with your uncle and aunt?" Liu Qingmei's question received no response, which only strengthened her resolve.

Over the years, the neighborhood has made many speculations and inferences about the mysterious disappearance of the Yan couple, their huge fortune, and the many daughters they adopted.

Especially the Liu couple, who had only brief contact with the Yan couple, and whose daughter had a very close childhood relationship with Yan Jiangchen, naturally wondered from time to time about the true identities of the other's parents, and worried that the mysterious disappearance might leave behind troubles that could affect their daughter.

Therefore, when Yan Jiangchen told Liu Qingmei the website address and purpose, she had no doubts at all. Instead, she kept her promise and firmly believed that he could overcome all difficulties to find her!

"Host, are you worried that the protagonist will take advantage of your relationship with your childhood sweetheart and just sleep with her?" The little white cat, its mouth stuffed full of dried fish, muttered softly, "Although I set up the account and password, the protagonist will inherit your memories, so he'll know about the agreement!"

Jiang Chen leaned back in the comfortable recliner, tapping his fingers on the wooden handle, and said softly, "Regarding my knowledge that the protagonist will transmigrate and replace me, the main system will definitely erase it and make relatively reasonable compensation."

In this way, the promise I made to my childhood friend will differ from the original plan in the protagonist's altered memories.

After the protagonist transmigrates, he inherits the original owner's fourteen years of memories, as well as a portion of my memories from the ten years I experienced after transmigrating.

Adding to his existing memories, this information becomes rather confusing.

I bet the protagonist will think the private website for the two to communicate is just a novelty, and the five-year agreement is just a naive idea born of youthful arrogance.

Most importantly, I told Qingmei about the five-year promise.

She will remember it well and make sure the protagonist doesn't make a move on her; otherwise, it will be noticed that something is amiss.

It was all a bit complicated and the little white cat didn't understand.

But it still clapped its paws and showered it with compliments, saying, "My host is truly the best!"

Chapter Thirteen is here! He's transmigrated here with ambition!
