Five years later, the Interstellar Warrior's body will be basically mature, and a new genetic seed will be generated inside, which can be extracted for the development of the next recruit; the second seed will mature in ten years, but it can only be extracted after the warrior's death.
Each Interstellar Warrior can only produce these two seeds in a lifetime. This also means that genetic seeds are incredibly precious.
If we solely rely on the fifty seeds we have on hand, and want to slowly bring the battle group back to its peak, reaching a scale of a thousand warriors, it would take at least a hundred years even under the most ideal circumstances.
Moreover, such ideal circumstances are fundamentally impossible. Not to mention, the battle group has to pay a genetic seed tax, and 5% of the new genetic seeds from the group need to be handed over to the Empire.
