The function of the tombstone and the Dead Soil share a similar aspect, converting elemental power into negative energy and death energy.
However, compared to the Dead Soil, the tombstone lacks a crucial function, which is to allow the souls of the departed to rest in peace, thereby achieving the self-cycling birth of the Undead.
Initially, the Graveyard of the Dead was only about a kilometer in diameter.
As time passed and Levi advanced to the seven-circle, its area constantly expanded, now over a hundred kilometers in diameter. It's not large, but sufficient for the Undead to survive.
After all, besides the Graveyard of the Dead, Levi also has the Black Soul Demon Tower, which comprises its own space capable of absorbing the negative energy of death scattered between heaven and earth.
Levi estimates that after advancing to the eighth-circle, the Graveyard of the Dead should reach a diameter of more than a thousand kilometers, thus having a preliminary scale.
