Forbidden Vault (4)

Death Grudge.

As a one-time special weapon.

Just as all the listeners had imagined.

Although Ludavira's explanation had made the thing sound utterly ordinary, with no flashy introduction or special functions whatsoever, it seemed to do nothing more than enable an extreme one-for-one exchange, like a super grenade.

But often, the plainer and less showy a function was, the more practical it tended to be...

Ludavira had chosen to use special means to remotely send countless special devices capable of collecting Negative Energy, Negative Emotions... to different points in time across countless parallel universes, thereby creating countless resource-collection sites to lay the initial groundwork for the manufacturing plan.

That was an incomprehensibly long span of billions upon billions of years.

And for a universe, at every single moment, countless lifeforms would continuously produce all kinds of Negative Emotions and Negative Energy...

Therefore.
