Therefore, the only path lying before Yan Fei was to design a Space Battleship by himself. Fortunately, Yan Fei had anticipated this situation and made arrangements for Yang Qi to design the Space Battleship in advance. As long as Yang Qi's design can pass the Drone's technological validation, then the Drone can be upgraded according to this design pattern.
However, the design of a Space Battleship is extremely time-consuming; even if it isn't produced, just as a data model alone, it requires validation of numerous technologies. Even with Yang Qi in charge of the project and the assistance of the technology extrapolation system, it would be impossible for Yang Qi to complete it in a short period.
