After returning, Zhao Guang immediately started designing blueprints and proceeded with developing new technology.
Because in Zhao Guang's mind, the second-generation spaceship was the true spacecraft, so it had to be completed. Moreover, in Zhao Guang's vision for the second generation, there wasn't just one type, but rather a category of them.
Some are responsible for transportation, others for combat, and essentially there should be all types.
As for whether there are enemies in outer space, Zhao Guang had already ignored that; after all, there must be a combat mode.
With no imaginary enemy, just consider the battleship as the hypothetical foe. Designing tactics against oneself surely shouldn't be a problem.
If others knew about Zhao Guang's idea, one can only imagine their expressions. Designing for combat against oneself; this might not be something a sane person can come up with.
While Zhao Guang was busy designing battleships, others were equally occupied.
