Ves spent almost half a day inside the vault. Though it didn't offer any proper lab facilities, he didn't require any. Not a single piece of lab equipment could do anything meaningful to spiritual energy.
As Nitaa stoically remained on guard and Lucky dozed on the deck, Ves continued to fumble with the tiny sample.
He tried various ways to extract its spiritual energy and transfer it to a P-stone.
Suffice to say, this was easier said than done.
Due to the living properties of the serum, its spiritual energy was essentially tied to its existence.
Ves couldn't just scoop it out and drop it into an empty P-stone. He first needed some way to separate the bonds that held these two elements together.
In essence, it was no different from harvesting a life.
Though it all sounded macabre, Ves didn't have any trouble with it. He would hesitate if he was about to perform this procedure on a living person or one of his mechs.
