Looking for a time-travel novel

I don't remember much of the content. I've seen it before in Red Sleeves Adding Fragrance. It should be a fictional novel.
The female lead was an assassin who had lived in the modern era. She had a very cold personality and knew many long-lost martial arts.
He still remembered that part of the content was about playing basketball. He used some kung fu and seemed to have attracted the attention of some people who knew kung fu.
Because he was an assassin, he had also accepted assassin missions after transmigrating to the modern world. He had never failed, so he was somewhat famous.
He seemed to have taken in a male disciple to teach him martial arts.
He had even brought this male disciple to sweep the female master's tomb, only to find that it had been robbed and that some of his weapons had been taken from the tomb.
He told the male disciple about his background. He was surprised but comforted her that he would accompany her.(I don't remember. Anyway, he said something to the female protagonist, which made the female protagonist feel a little moved.)
It seemed that she had once gone to a very cold place (and it was snowing) to pick a kind of medicinal herb (which should be able to increase her martial arts) for the sake of her male disciple. She almost couldn't endure it. Fortunately, she met a small white thing (I forgot what it was). That small thing left that cold place and followed the female protagonist back to her residence.
When she returned, she couldn't find the male disciple. She asked his friends where he had gone, but they were hesitant.
In the end, she found the disciple in a square. There seemed to be a woman beside him who was very close to him. When she saw the female protagonist telling her that she was only good to her because of her martial arts, the female protagonist threw the herbs she picked on the ground and turned around to leave.
That was all I saw at that time. Now, I want to find this book. I'm not too sure if there's such a book because I saw it in Red Sleeves Adding Fragrance. Now, I want to find it, but I've forgotten the title and the female protagonist's name. I only remember fragments of the content.
Help me out if you know. Thank you.
