Plan!
This was the most terrifying thing he knew from Tuman's memories, and it was also the origin of everything. It was about Nero.
And this had to start with Nero's disappearance more than 500 years ago.
500 years ago, the Abyss had undergone a change, and a large number of demons had invaded. As the ruler of the Heart of the Abyss, Nero was naturally duty-bound. At that time, he had killed countless demons as a half-step fifth-circle demon. In order to find the reason, he had even entered the Abyss.
Then, he disappeared.
Three years later, when everyone thought he was dead, he walked out of the abyss.
No one knew what Nero had encountered in the past three years.
However, Tuman was the first to find out.
