There was almost no flesh on her back, she was skinny, and she poked to the bone.

Probably Su Mu lifted her quilt a little cold, or maybe his fingertips were a little cold, Su Xiaoli snorted twice, hugged the doll in his arms, turned over, and continued to sleep.

Su Mu hurriedly pulled off her pajamas, and then covered the quilt again.

I don't know what kind of life she lived before she came to her house.

Su Mu lay on the bed, supporting his chin with one hand, looking at Su Xiaoli with his back to him, he only felt a little distressed inexplicably.

He stretched out his hand and gently patted the quilt on Su Xiaoli's body, thinking silently in his heart, from now on, you will have a brother to protect you.

——

Three years later.

In Z City in September, the sky is clear and deep, the air is clear and refreshing, the autumn wind blows, and the white clouds in the blue sky float leisurely.

Su Mu is already a sixth-grade student and has begun to prepare for the exam for junior high school, and Su Xiaoli has also begun to enter the second grade of primary school.

In just three years, Su Mu has changed from a scumbag within dozens of students in a class to a top student in the positive grade, and has become what parents call "someone else's child".

And there is only one reason for all this - that is Su Xiaoli.

Since Su Xiaoli was in the first grade of primary school, he began to ask Su Mu all kinds of questions every day:

"Brother, what do you pronounce this word?"

"Brother, how to do this question?"

"Brother, how high is the sky and how many stars are there in the sky?"

"Brother, how many languages are there in the world, and how many do you speak?"

In order to satisfy his sister's thirst for knowledge, in those years, Su Mu turned over "One Hundred Thousand Whys", memorized "Three Hundred Tang Poems and Song Poems", and read several original English fairy tale books.

So inexplicably, he won the first place in the essay competition, the first place in English speech, the first place in the primary school mathematics Olympiad and so on.

After getting so many first places, Su Mu is simply a red and blue BUFF, and even the teacher is about to think that he is a prodigy.

And Su Mu, who is handsome and has good grades, naturally became the crush of the girls in their class.

It's just that in view of someone's personality being as bad as ever, those girls can only silently like him in their hearts.

But as the saying goes, if you don't explode in silence, you perish in silence.

At the end of school that day, Su Mu went to Su Xiaoli's class to pick her up as usual.

Far away, when he was about to arrive at the door of Su Xiaoli's class, he had already seen Su Xiaoli's fair and pink little face peek out of the back door of their classroom.

"Brother!!" As soon as he saw Su Mu's figure, Su Xiaoli immediately waved his little hand at him, like a happy bird, and ran towards him.

"Good." Su Mu looked at Su Xiaoli, who threw himself directly into his arms, smiled at her, reached out and touched her head and asked, "Do you have a lot of homework today?" ”

"Not much." Su Xiaoli shook his head, obediently stuffed his little hand into Su Mu's hand, and then followed him as he walked: "The teacher said that in another week, the sports meeting will be held, brother, how many events do you plan to participate in this year's sports meeting?" ”

"I haven't figured it out yet, so let's arrange it whatever the teacher wants." Su Mu thought for a moment and replied casually.
