The air fell silent instantly, so quiet you could hear your own heartbeat.

"good."

Grandpa Qi nodded. "Alright, come with me."

The old man quickened his pace considerably, unable to conceal the excitement in his eyes, and hurriedly walked outside. The butler followed behind, his expression also changing considerably.

Qi Silin remained silent, simply following behind Old Master Qi.

Soon, the four of them arrived at the somewhat old side building. The butler looked at Old Master Qi with a mixture of relief and excitement in his eyes.

After so long, have we finally found it? We've waited so many years, and we've finally found it.

Opening the door to the side building, the scene inside immediately came into view.

The exterior of this annex is completely different from its interior; it's spotless inside, and you can even smell a faint scent of sandalwood. It seems the Qi family has kept this place very well.

"Qiqi, come with me."

Qi Jiu hummed in agreement and followed the old man upstairs with Qi Silin, arriving at the second floor of the side building.

Actually, this side building is only a little smaller than the main building, but it still has a lot of rooms.

Looking at the spotless escalator and doorframe beside her, the girl knew that Old Master Qi must clean this place regularly, and she could also see how much he valued the things inside. For some reason, she felt a little nervous at that moment.

Soon, Grandpa Qi stopped at the door of the room at the very end of the corridor. He glanced at Qi Jiu first, then took out his key and opened the door.

"Smack!"

The moment the lights were turned on, the room's furnishings came into view.

The room was decorated neatly, like a study. There were many books on the bookshelf, and next to the bookshelf was a spotless desk, next to which was a small bed.

The room was furnished in a very conventional way; it looked like an ordinary room, and no one would have guessed that it contained a huge secret.

"Come in."

Unlike the living room, this study doesn't have enough space for chairs, so the old man could only point to the bed next to it.

"Sit down." He paused, then looked at Qi Jiu. "What do you want?"

"That letter, the letter that can prove my identity."

As soon as he finished speaking, Old Master Qi's eyes suddenly reddened, and his gaze towards Qi Jiu changed somewhat. His voice even became choked with emotion.

"Okay, okay, Grandpa will get it for you."

The butler watched from behind without saying a word, looking at Qi Jiu with a very kind gaze, as if he were looking at his own granddaughter.

After so many years and so many things, they have hoped and been disappointed time and time again. This time, they have finally waited for it.

Soon, a somewhat worn envelope appeared before Qi Jiu's eyes.

Perhaps because it's been too long, the envelope got wet for some reason, and now some of the writing is unclear.

"Qiqi, here is the envelope you wanted."

The girl lowered her eyes, her brows furrowed, as she looked at the envelope in her hand. As she opened the letter, strong, forceful handwriting appeared on the paper. It seemed this person had been a strong and resolute individual in life.

Meanwhile, Old Master Qi kept his gaze fixed on Qi Jiu's face, as if scrutinizing her.

Finally, his eyes welled up with tears. "Old friend, I've finally waited for this child. I've completed the task you entrusted to me. Rest in peace now."

As she read the lines of text on the letter, the girl's expression subtly changed.

"The Delin family? So I have a name after all."

From as far back as I can remember, I thought I was an unwanted orphan, so naturally, I chose this name myself. The first numbers I knew were 7 and 9, and over time, those became my name.

As she spoke, the girl gave a bitter smile, looking at the somewhat unfamiliar family and names on the letter, her emotions unable to be concealed.

"Actually, you are all of Chinese descent, but at the time, circumstances forced you to leave China. Later..."

"The principle is that a traitor appeared in the family and created 'Zero,' thus beginning the feud between the Delin family and Zero, right?"

This story is a bit melodramatic, but that's the truth.

The envelope contained quite a bit of information, and Old Master Qi nodded.

“Child, I don’t know what you’re thinking right now. You can blame them, but what I want to say is that they were protecting you when they were alive—your grandparents and parents.”

Grandpa Qi sighed with some emotion, but now, seeing the envelope in the girl's hand, he breathed a sigh of relief.

He thought he would never live to see it again.

Fortunately, fate was on his side, allowing him to wait for the arrival of this child. No wonder he liked the child so much from the very beginning; it turns out there was another reason for it.

Qi Jiu looked at the letter in her hand, as if she had thought of something, and looked like she wanted to say something but couldn't.

"Grandpa Qi, do you know what the relationship is between Han Yan, the current owner of an international assassin organization, and the Delin family?"

If the Delin family is the one with a grudge against Zero, why are they targeting Han Yan? Is Han Yan also from the Delin family? There are too many questions.

Grandpa Qi was taken aback, seemingly not expecting her to ask this, his eyes somewhat glazed over. "Qiqi, do you know that guy Han Yan?"

The girl nodded. "Yes, he is my master now."

Grandpa Qi was taken aback, then suddenly smiled, seemingly pleasantly surprised, an unexpected surprise.

“Alright, alright. Han Yan has no relation to the Delin family, but he received favors from them when he was young. He is on good terms with the Delin family, just like me.”

So that's how it is.

The girl pursed her lips, looking at the dense handwriting on the letter in her hand, feeling a mix of emotions she couldn't quite describe.

At night, the stars in the sky are bright.

In the villa area, Qi Jiu looked at Qi Silin, who was staring straight at her, and sighed countless times before finally deciding to speak first.

“I admit that my initial purpose in coming to China and getting to know you was for a mission, but I only found out later that this mission was this.”

The man blinked, his face expressionless, neither disappointed nor angry. "So, you gave up halfway through?"

The girl had tried to subtly probe the matter several times before, but she hadn't taken any action. It seems the task has been shelved.

Qi Jiu nodded.

"yes."

"So, your feelings for me are genuine, right?"

Under the dim light, the man's eyes were somewhat indistinct, yet they possessed a unique charm.

"yes."

"That's good. As long as your feelings are genuine, what's wrong with using me?"

The sun was shining brightly that day.

The girl clutched the letter she had brought back from her family's old house and fell into deep thought.
