This egg like thing was not just egg like but it was actually an egg. And inside this egg, a life was being revived.
And obviously, the lifeform that was inside this egg was the Lich Overlord. But after coming out of the egg, it would not be the Lich Overlord anymore.
Actually, this being would not even be an undead any longer. By this method, the Lich Overlord would be able to perfectly revive himself and would also be able to regain his features from his previous life before he had turned into a lich.
Not just that but by actually dying, this individual had managed to separate himself from the control of the dungeon. So after coming out of the egg, he would be completely indipendent in a better way than Kumoka.
