Gene Field

All the genes that Phantom collected from the monsters were stored in the Vault, moreover, after Phantom became K2, opening the first keyhole in his Lock, the Vault underwent significant changes.

The Gene Cube appeared, a special area within the inner space. The Gene Cube could hold objects with large amounts of energy in ghost form.

So... when Adam heard Damien's words, he was greatly stumped.

"What, The Vault is useless? What do you mean?" Adam asked, casting a glance at Damien, he wanted to figure this out.

Damien smiled bitterly.

"Well, sure, the Vault itself is indeed useful, without it, the Phantoms couldn't even store harvested genes, but that's not what I'm talking about, it's one feature."

Adam tilted his head in confusion. Strangely enough, he didn't understand what function Damien was talking about, as if they were talking about different things.
