My backyard leads to the underworld. I became famous by selling goods.

Meng Qi then asked, "Are the research results you previously obtained also in your original room?"

"Maybe. But in our current state, there is no way for us to go back to my original room to find out." Quan Zhi said this, and cast an expectant look on Song Mian.

Song Mian cleared her throat, picked out a light blue evening gown from the closet, and said to the housekeeper, "I'll take this one. Excuse me, could you find me a guest room so I can change? There are too many valuables in Miss Quan Yanyan's room, and I'm worried I might accidentally damage them."

Not to mention Song Mian, the housekeeper was very cautious after entering Quan Yanyan's room. He agreed to Song Mian's request immediately, took her out of Quan Yanyan's room, and went to the guest room next door.

After telling the housekeeper that she could change her clothes and go directly to the dinner, Song Mian pretended to enter the room, but actually she was lying on the door, paying attention to the housekeeper's movements outside.

The butler's footsteps outside the door gradually faded away. After Song Mian was sure that the butler had left, he quietly pushed open the door and asked, "Quan Zhi, where is your room?"

"It's upstairs, on the top floor." Quan Zhi said as he walked forward in the direction he remembered.

Looking at Quan Zhi's stumbling back, Song Mian hurried to catch up.

The family villa has five floors in total. Song Mian went up to the fifth floor and found that most of the rooms were used to store miscellaneous items.

"Quan Zhi, which room is yours?" Song Mian looked behind her cautiously while speaking, fearing that while they were talking, the people from the Quan family would notice that she was missing and come looking for her.

"Neither, my room is upstairs." Quan Zhi said in a daze, and slowly floated upstairs.

"What else is upstairs? Isn't it an attic? Which young lady would live in an attic?" Meng Qi said, with some disgust in his tone.

Quan Zhi did not respond to Meng Qie's question and floated towards the attic.

Song Mian followed Quan Zhi all the way to the attic.

The small vermilion door of the attic was locked with a small lock.

"Young boss, the key is under the small flower pot on the ground at the door."

As Quan Zhi said, Song Mian indeed found a small key under the small flowerpot.

After successfully opening the small lock with the key, Song Mian pushed open the door in front of him and heard the creaking sound of the closed door.

A thin layer of dust had accumulated in the attic, which had not been visited for more than half a year. After Song Mian walked into the room, he found that there were very simple tables, chairs, benches, a small bed about 1.2 meters long, and a shabby wardrobe.

The room was only about 20 square meters in total, and was visibly simple. It was not even as luxurious as the guest room Song Mian had just visited.

The small attic is completely incomparable to Quan Yanyan's room.

"Quan Zhi, are you sure this is really the room you live in the Quan family?" Song Mian's eyes were filled with deep shock, and he couldn't believe his eyes.

"Yes." Quan Zhi came to the very simple bedside table, pointed at it and said to Song Mian, "Miss Song Mian, I remember there is my diary in this bedside table. Please help me see what is written on it."

Song Mian immediately opened the bedside table and was surprised to find that there were indeed many diaries in it.

These diaries are the simplest notebooks. They are stacked up neatly and look well organized.

Song Mian took out the diary at the bottom, unfolded it and began to read it carefully.

"May 12, 20XX, is my eighth birthday. I had been dreaming of cake and family, but to my surprise, my parents came home and told me I wasn't their child. They wouldn't let me get close, and I was terrified.

I wanted to go find my brothers, but they scolded me, saying that I had taken their place as their real sister. But what is a real sister? I am obviously their sister too, so why do they say that to me? I don’t understand…”

When Song Mian read this, he also saw tear marks in the shape of water droplets on the paper.

With her heart uncontrollably tightened, Song Mian looked up at Quan Zhi and asked, "Did the Quan family know whether you were the daughter of the Quan family when you were eight years old?"

Quan Yanyan and the Quan family never mentioned this to her.

They thought that Quan Zhi was driven out of the Quan family and forced to give up her princess-like life only after Quan Yanyan was found and brought back to the Quan family.

Now it seems that she has been treated coldly by this family for a long time!

No wonder, no wonder the Quan family was so decisive in driving Quan Zhi away after finding Quan Yanyan.

It turns out that they didn't treat Quan Zhi as family members!

Quan Zhi took the diary handed to him by Song Mian in a daze.

Song Mian also continued to look at the diary.

These diaries started from Quan Zhi’s eighth birthday and continued until he was eighteen.

During these ten years, every bit of Quan Zhi's experience in the Quan family was simply recorded in ten diaries.

These ten diaries record the past, which is the extremely important and difficult ten years in Quan Zhi's short life.

During these ten years, Quan Zhi grew from a helpless eight-year-old child who was suddenly abandoned by the Quan family, and gradually grew into numbness.

During this period, Quan Zhi wanted to get along well with the Quan family again more than once, even thousands of times.

But her parents hated her, and the three brothers of the Quan family regarded her as the culprit who had taken away Quan Yanyan's good life.

She tried her best to study, get scholarships, and buy gifts for her family.

The result was insults and ridicule, and he was even labeled a "thief".

All this was just because she took Quan Yanyan's position without knowing it and was pampered by the Quan family for eight years.

Soon realizing that his efforts could not be rewarded by the Quan family, Quan Zhi even wanted to go to an orphanage.

However, the Quan family could not tolerate the scandal of their lost daughter, so they signed a contract with Quan Zhi, requiring Quan Zhi to wait until she turned 18 before she could leave the Quan family.

Before that, she needs to stay in the Quan family to forgive her sins and make up for her sin of monopolizing Quan Yanyan's favor.

Fortunately, Quan Zhi is a genius. She is not only good at studying, but also has superhuman talents in various fields.

So she thought of a way to repay the favor.

She fanned the flames and tried every possible way, both overtly and covertly, to help her three brothers become bigwigs in various fields.

The three young masters of the Quan family only knew that someone had been providing them with help, but they didn't know that this person was Quan Zhi.

Quan Zhi could have told this to his family on his eighteenth birthday.

However, Quan Yanyan appeared at that time and plagiarized her paper.

That paper summarized all the details of her help to her three brothers so far, and it is also the argument of this paper. It can perfectly prove that Quan Zhi is the one who has been silently helping her three brothers behind the scenes for so many years.

It was this paper that was plagiarized by Quan Yanyan.
