After Elia recorded everything about the Liber Chaotica and her insights into the Absolute Curses to the best of her current ability, she respectfully handed the wisdom tome to Jacob.
Jacob received the wisdom time and stowed it away in the infinity pendant, as this wasn't the time to immerse himself in it for now, nor was he planning to enter the infinite space and seclusion.
After all, the presence of the Undead Skyfall had given Jacob an unexpected surprise, not to mention he never planned on returning after just taking away Elia.
Jacob then looked at Elia, who seemed to be filled with anticipation, and impassively asked, "For hundreds of years, you have been constantly placing yourself in danger while overcoming death at every corner, but you didn't succumb to despair and give up. That's why you deserve your place by my side, and now, since your task has been completed, you deserve rest and peace."
