Ask for the name of a novel

Maybe it can't be called a novel
Just a short story
a short
It's about not knowing which dynasty
The earliest was the uprising. A few youths who were injured and hunted by the imperial court fled to a village and were taken in by a family. This family had an eight-year-old…A little girl who did not know how old she was... I don't remember her name.
The male protagonist seemed to be called Cang Lan, or something like Vermilion Bird and Black Tortoise.
Later, the court found out the whereabouts of the rebels and went to the family in the village.
No matter what, their family was unwilling to reveal the youngster's whereabouts.
Then the head of the court killed the girl's parents and left a long scar on the girl's face
Later, the male lead seemed to have said that he would take care of the female lead for a lifetime
The female lead seemed to say something about marrying the male lead when she grows up
P.S.: Male protagonist is 10 years older than female protagonist.
Then they hid in a valley
The female lead seemed to have been with the male lead until she was 18 years old.
As a killer, killing officials of the imperial court
When the female protagonist was 18 years old, she said that she wanted to leave the valley and didn't want to kill anymore.
There are rules in the gang. The female lead can't leave just like that, as if she has to go through something before she can leave.
It seems to be defeating the four masters in the gang
And these four masters and the male lead were the teenagers who lived in the girl's house back then
Very good to girls
I want to help the girl fulfill her wish
In the end, it seems that the girl has to leave
The male lead let the girl drink that
forgetting everything
After the girl left the valley, the gang slowly disbanded
Because people are already living in peace and contentment
No longer treating them as rebels, but as bandits
.....
The ending seems to be
The male protagonist passed by a small shop
He saw the little girl outside the store singing the song he taught the female protagonist.
Then he walked into the store and was greeted by a simple and honest man
When he's about to leave
The female lead walked out.
But I don't know him anymore
He didn't want to disturb her life now.
said nothing
and gone
complete
Do you know what it is? I want to show one of my classmates
But I just can't find it
Everyone, help me recall.
If you get it right
I still add points
thanks
