First time reading since 2023

So the last time I read this was back in 2023. I got pretty far into the novel, but now I started reading the manhwa again from the beginning and I'm getting confused as hell 😭

Whenever I see characters I'm familiar with, I start trying to remember what happened in the novel and whether I'm actually remembering it correctly.

From what I remember:

- Jin and the assassin sister got pretty close, and I vaguely remember them giving each other flowers or something like that.

- Luna eventually swore loyalty to Jin and agreed to serve him.

- I remember Veradin, and I think Jin and Veradin went on some kind of adventure together? I also vaguely remember Jin having another friend with them, but I can't remember who.

- Jin also acted as an assistant/apprentice to someone with anti-magic abilities, if I'm remembering correctly.

- I remember the leader of Kinzelo appearing. I think his ability had something to do with mirrors/light?

- And one thing that's really messing with me is the whole tomb thing. I remember there being multiple tombs, including one at the bottom of the sea. But now I'm wondering if I'm mixing this up with another story 💀

If these things are actually from Swordmaster’s Youngest Son, does anyone know roughly which novel chapters these happen in? And how far has the manhwa adapted into the novel by now?

Basically, I read the novel a couple years ago and remember a bunch of random events but not where they happened, so I'm trying to figure out how far I actually got in the novel and whether the manhwa has reached that point yet.
