hi! its on book 3 on the novel, the time where the butler told hue that lucia's montly visit is somewhat irregular (that's chapter 58-59 on the manhua) . i cant really pin point what chapter you should read since its quite different the way they reflect it on the actual manhua. so i suggest start reading on book 3 (chapter 25) so you could uhm somewhat understand it better and also since it got a lot more details on the novel than the manhua. the way they show it on manhua is a little bit shorter than the novel.
anyways, here's the link:

and if you have time. read it from chapter 1 hahaha
chapter 65 (latest in manhua) would be somewhere in chapter 28 (book 3) in the novel. but yeah, its better to start reading from chapter 25.
On the latest chapter of manhwa Lucia, what chapter is it on in the novel? Sorry, I can’t wait till it gets translated so I want to real the novel. (￣∇￣")
