With the new war-bond funding from Pan, Kita redoubled his efforts. He expanded the cave and divided it into multiple dissection rooms so that pieces of the carcass could be studied in parallel. A system of carefully drilled holes and mirrors directed filtered sunlight to illuminate the interior of the cave, and he designed a concave frame with numerous refracting glass lenses to be placed over the dissection tables so that no shadows would block the view of the operating surgeon or dissector. To cut through the tough skin, muscle, and tendons of the giant beasts, he commissioned diamond-tipped scalpels to ensure the cuts would be smooth during the dissection process and avoid damaging the tissues needlessly with hacking and sawing. He set up several windmills on top of the cliffs above the cave, from where a series of gears and belts transferred the power down into the lab, where they operated heavy machines for lifting and moving the carcass around. Since the entire space was maintained at near-freezing temperature, everyone working inside had to dress as though it was deep winter. Except for scholars and workmen approved to work on the project, no one was allowed anywhere near the hidden laboratory: Lyucu spies and sympathizers might well attempt to sabotage the work being done here, and whatever revelations they might learn would be military secrets.
