@myisekiaadventures Not really sure, perhaps the guy that wants to destroy the world who keeps killing the ML? Although, I feel like he would have just immediately tried to kill her if it was him. If anyone has a spoiler about it I'd appreciate it.
That identity in the dungeon/Abyss is the 116TH Thesilid. Eillet only know about him until the 100th Thesilid which is "Reid" and she does not know what happened to Thesilid after it. So Reid got defeated by this 5 powerful people and imprison Thesilid in that abyss where they let him drink the Water of Life which will give him lifetime suffering (this hurts so much promise ) and another is that disk which Eli got was a save point where let Thesilid regress and comeback to that save point which is like a time loop So he suffer 16th time to that abyss/dungeon (so that's why the disk has 14/30 remaining save point ) and what happen to Thesilid when Eillet got that save point is another spoiler!!! 🤫🤫🤫
I can share the website where I read the novel it's actually ongoing with 177 chapters right now. 🤫
