Ask for the full name and author of a novel

The title of the novel was probably " Transformation into a Nine-Tailed Fox ", but there were many people with the same name, so it was not easy to search.
The content was about the male protagonist accidentally becoming a foreign world. A young female nine-tailed fox was thrown off a cliff by her parents at the beginning. She was lucky enough to not die and even obtained a super system. Then, she cultivated and grew.
When he reached a certain age, he would trigger the system and enter the world of Pokémon artifacts…
After coming out of reality, he met a woman who was beaten up and saved her. Then, the woman was the principal of a school. The protagonist arrived at the school and was hunted down by the entire school. In the end, he used his superhuman ability to beat up the principal who was full of clothes and even made a school cleaner work hard.
Then, the system gave him a super maid. After that, he did not know.
She suddenly remembered that she had seen it a long time ago, but she couldn't find it.
