Due to the difficulty of reconnaissance resulting in a lack of relevant intelligence, the "Sagali" civilization seems like "watertight" and cannot find a point of attack. Now, finally, a crack has been pried open by force.
No matter how strong the fortress, it is often easiest to break from within. This crack originally did not exist, but as they say, "the bell must be unrung by the one who rang it," the reproduction lock set by "Sagali" through the "Seed Nest" was, in the end, unlocked by another form of the "Seed Nest" — the "Life Tree."
Parasitic Species can no longer control the survival of Enslaved Races. Even if all currently controlled Enslaved Races were to perish, these races would still have the chance to continue through the "Life Tree" and regain reproductive ability crucial to their destiny.
