Although Qiongqi was a bit slow on the uptake, it proved sufficiently capable. And, to be honest, operating a flying ship was much easier than calculating a Sword Array, after all, one didn't need to understand the workings of every single component inside a refrigerator, just how to open its door.
After mimicking the operation of the ghosts, Li Fan not only learned how to pilot the various devices within the shuttle, but he also found a 3D printer, or rather, a food synthesizer.
This device could take various organic materials, outrageously speaking, dig some soil, mix in some water, process and purify it, and ultimately produce emergency food similar to compressed biscuits. It was presumably a cheap device used by these clone bio-soldiers. The taste was indeed hard to describe, but the upside was that it was highly adaptable, low in cost, and the quantity was sufficient to fill one up.
