Helenberg had long-term leased a warehouse for storing alchemical raw materials at the Kaiming Academy in Lumingtun.
He was a man who maintained clear boundaries between public and private, and would not replenish his stock by taking assets from the Ocean Observation Room.
These raw materials were obtained from point exchange, or by hiring others to collect them from the public areas of the Mediterranean.
Helenberg planned to use the lungs of a massive whale-like demon as a prototype to create alchemical lungs suited for a bionic human body.
Conveniently, his raw materials warehouse housed a full pair of demon whale lungs.
The moment Helenberg obtained this precious sample, he deeply understood its invaluable importance for future use.
So, he spent a fortune buying expensive oil, and wholly submerged the demon whale lungs - about the size of three adult humans - into it.
