I recommend the book " I Use Technology to Rebel the Cultivation World " to you. It was also a time-travel novel. The protagonist had the technological knowledge of his previous life and successfully made a comeback in the cultivation world, while the male protagonist used the female protagonist's knowledge and skills to help him achieve his goal. This novel had many ingenious alchemy methods and weapon designs, as well as various exciting fighting scenes and emotional entanglements. I hope you will like this novel.
