There were many kinds of water pumps she knew of, all relying on various scientific principles. After much consideration, An Jin settled on the piston pump.
Its structure was simple, it was easy to operate, and it could be built even in the technologically backward Beast World.
The principle behind a piston pump was actually quite simple—it used atmospheric pressure to draw water upward.
She worked through the night to draft a design for a hand-cranked piston pump. It had the dual function of pumping both water and air, which was incredibly convenient.
After handing the design to the Beastmen in the workshop, she left with her mind at ease. The finished product would be ready for pickup in three days.
After several years of training, the craftsmanship of the workshop's Beastmen had become increasingly refined. Their mastery of dimensions and measurements was flawless; as long as she provided the design, she was guaranteed to receive a perfect replica.
