"A key? What exactly is this 'key'?"
In the Netherworld, Heine squatted indecorously at the entrance of the Tower of Nether Dust, deep in thought.
First of all, the tower was asking for a "key," not "insufficient permissions."
Furthermore, he was quite certain that Anson hadn't spoken a word when he retrieved that clump of skill books for himself.
So, this so-called key was not something that had to be verbally commanded, but rather a spell to be activated.
So… was it a necromancer's spell?
Where in the world would I find that…
Suddenly, a familiar soul fluctuation invaded Heine's perception.
Anson?
Heine was startled and instinctively used stealth.
He hadn't expected that the Nether Spirits here could also recognize his spirit communication art and faithfully execute his request.
Even more so, he felt a trace of panic from the response of these Nether Spirits.
