Norma's Sin!
Tang Qi and Sally entered the Illusion World together, where the Master was the imprisoned personality "Norma" — the one she had abandoned. The turning point of abandonment was precisely the scene that had once occurred on the Immortal.
The real Samuel Winston had died, chasing after the Immortal.
It was the death of the real Earl that spurred Norma's transformation.
She devoured the Earl and transformed herself into Samuel Winston; she is the true Immortal Earl. Samuel Winston was nothing more than a reckless, green noble youth, whose sole contribution was to catalyze Norma's transformation and the birth of the "Immortal Earl".
And this moment, similar to the scene aboard the ship that day.
The difference was that, at that time, Tang Qi and Sally had watched as "Norma's parents".
The new "Source of stimulation" was not the death of Samuel Winston.
It was the Immortal, the last bond she had with Samuel, now gone.
