It was not the first time he had entered a Castle of Death.
The dead world he once visited, the place where he also saw the best Starry Sky he could have ever seen in his life, that terrifying place that no one usually visits in the Upper Realm had several.
That dead world was none other than the First World, the place where he saw that swordsman from the past when he received an epiphany from the System.
According to legend, that was the First World of the Upper Realm, and in the time of the Gods, it was where all the great powers of the time lived, including the Gods. That is why they say it hides the secrets of being an immortal, but the truth is that everything is far from reality.
Perhaps there are secrets there, but what abounds most is death.
For it was in that place that a deadly battle between the Gods and the Heir of Death took place; it was where everything perished, including the Gods.
