Ves scouted the containers even more. He explored numerous clusters and made sure to take a peek in each of them with the help of Blinky. The companion spirit only needed a single glimpse in order to confirm whether any remaining phasewater was left inside.
He could not use the Phase King to sense the overall quantities of phasewater in all of the surrounding containers because the containers were made out of an alloy that was extremely effective at isolating phasewater.
Since each giant 'barrel' could potentially hold thousands of kilograms of pure phasewater, they had to be made out of excellently stabilized alloys that could withstand the constant spatial activity generated by pure phasewater.
Even then, Ves found it rather ludicrous to believe that all of the containers in this storage chamber collectively held hundreds of thousands of kilograms of phasewater!
