Song Qingxue raised her eyes and looked at him with wide eyes, unable to speak for a long time.

It was clearly the first time they met, so how could he see it so easily?

Fear suddenly invaded her whole body, turning her face pale.

Seeing that her face had changed with fear, Song Qingfeng quickly said, "Don't be nervous or afraid."

"You..." Since he already knew that she was not the original owner, why did he still treat her like his own sister? She didn't understand.

Song Qingfeng probably guessed the doubts in her heart, and slowed down his tone and said, "In fact, as early as last year when the emperor was seriously ill, I guessed that you were not my little sister."

Hearing this, Song Qingxue was even more surprised.

So early?

But why didn't he expose her then, but instead sent people to secretly monitor her movements in the palace as he did before?

Moreover, his concern for her today did not seem fake.

He obviously dotes on his little sister so much, how could he allow someone to live in his sister's skin for so long?

Song Qingxue had countless doubts in her heart, but when all the doubts came together, she could only ask with a trembling voice: "Why?"

Song Qingfeng didn't even think about it and answered, "Because this skin still belongs to my younger sister."

Song Qingxue bit her lip and considered her words before speaking: "Don't you hate me?"

She stole the body of his most beloved sister. Did he really not hate her at all?

"No hatred." He looked up at the sky, looked at the stars and said slowly: "My little sister is such a strong person, I believe your coming here must have been allowed by her. Since she is willing to give you the right to use this body, then you are my little sister."

"You really are open-minded." Apart from the word "open-minded", she really didn't know what else to say.

"Even if you can't let it go, my little sister can't come back. This is her fate."

Song Qingfeng turned around and smiled at her, then continued, "But, actually, you are quite good too. At least you have improved my reputation, and when people mention Song Qingxue, they think she is a useful person."

Although he doted on his little sister, he knew in his heart what kind of person his little sister was originally.

He and his father really didn't mind her being arrogant and domineering all her life. After all, their Song family had military merits for generations, so they were not afraid of not being able to protect their only daughter.

But now that this little sister has improved her reputation, he is also happy to see it happen.

It was just that he didn't go to see his younger sister before she left, which was somewhat regrettable.

Thinking of this, he couldn't help but take another look at Song Qingxue.

The two of them are indeed completely different.

"Can you tell me when you came? How long has my little sister been gone?"

Song Qingxue thought about it and said, "At the beginning of summer last year, your little sister was really someone who didn't want to suffer any loss."

"Is that so?"

"Yes, I saw her when she left." Song Qingxue was a little helpless, "She borrowed my body to prolong her life, and asked me to help her do something. If I couldn't complete it, she would let me die of intestinal ulcers."

Song Qingfeng said: "This is indeed something she can do."

"So you know what a cruel person she is?" Song Qingxue said half-jokingly.

"I spoiled her myself, how could I not know." Song Qingfeng really knew his sister well. Even though he had never met her, he could guess that she was no longer his sister.

"Tsk, what a great brother."

Song Qingfeng smiled noncommittally and said, "Where are you from?"

"I came from another world." Song Qingxue answered, but she was a little confused. "No, why did you accept the idea of ​​reincarnation so easily?"

This matter was so mysterious that even she took several days to recover. But why could Song Qingfeng mention this matter so easily to the person who occupied his sister's body?

"As early as when I suspected that my little sister was no longer around, I had already checked many ancient books." It's not easy to accept.

At that time, he wanted to go to the palace to find his younger sister every day and verify it personally, but he was always busy with state affairs and could not spare the time to look for her.

Therefore, he had to take advantage of some scattered rest time to look through some books for research. He was lucky enough to actually find relevant content.

What was written in the book was very mysterious, and he didn't believe it at first, so he asked the people he had planted in the palace to observe Song Qingxue carefully, and found that she really had changed completely.

It would have been fine if it had changed, but it wasn't a gradual change, but it happened overnight, as if his temperament had suddenly changed.

In order to verify the facts during that period, he even asked someone to write down everything Song Qingxue said and did every day in a notebook.

Compared to the original little sister, she is really like a different person.

She had excellent medical skills and a gentle and clever temperament. According to the people he sent, many maids in the palace wanted to serve in her courtyard, but unfortunately there was no shortage of people in her courtyard, so there was no chance to squeeze in.

If other information cannot prove that a new person has been replaced, this sentence can definitely prove it.

Because my younger sister had been spoiled and domineering since she was young, her yard was often the place the maids were most reluctant to go to.

Fortunately, Liu Huan, who grew up with her, never left her side, otherwise taking care of her daily life would really be a headache for him and his father.

"What? The ancient books here have records of this kind of fantasy world?" Song Qingxue was shocked after hearing this. It turned out that science is no longer important in the world you travel to, right?

Her big reaction surprised Song Qingfeng.

"Don't you have it in your world?"

"No." Song Qingxue said: "In my world, we don't practice metaphysics. Everyone believes in science."

"What is science?"

"Um... probably, proving the existence of something through practical action?" It's hard to explain, really hard to explain.

"Oh." Song Qingfeng nodded, not quite understanding, and said, "Then the reincarnation of the dead really happened to you, so it can be considered scientific, right?"

Song Qingxue's expression became strange, and she stammered, "I guess not."

This kind of thing is beyond the scope of science and should be called theology!

Thinking of this, Song Qingxue suddenly became curious. Even time travel has happened, so is it possible to cultivate immortality in this world?

She looked at Song Qingfeng, blinked her eyes, and said, "Brother, when can you lend me some ancient books? I want to study whether I can cultivate immortality."

"What nonsense are you thinking about?" Song Qingxue gave her a slap on the head. "Instead of thinking about such vague things, you might as well think about when to get up tomorrow to practice martial arts."

"Ah?" Song Qingxue was stunned.

"When I came back, someone asked me to teach her martial arts. Are you going to regret it before the night is over?"

"That's definitely not the case!" Song Qingxue patted her chest and said, "I sincerely want to learn martial arts well."

Thinking of her powerlessness facing the secret guards that day, she became more determined to practice martial arts well.

In this world where swords and sabers can be seen everywhere, she can't expect anyone to protect her all the time. She was lucky that Lin Shu saved her life that day, but life is so long, how can there be so much luck?

"Since you really want to learn, then go to bed quickly. You have to get up early tomorrow morning for morning exercises."

"Got it, I'll go to bed now, good night, brother!"

"Good night, little sister."

Song Qingfeng watched her enter the house before turning around and leaving.
