The third target is rather inconceivable; that is, to directly airdrop onto continents that have already been destroyed.
These two continents are devoid of human life and even monsters, appearing extremely barren, but in reality, this is precisely where they can best leverage their faction's advantage.
The potential of First Level and Second Level Cosmic Civilizations is sufficient to thrive in such barren lands, where industrial and agricultural sectors can explosively grow, and most importantly, without restraint.
Although settling on continents dominated by humans is not out of the question, doing so would strategically slow down the overall development pace of humanity. After all, the human forces ruling over such continents, from what observations suggest, are fully committed to supporting the humans on the other ten continents. If they drop one, then the external support for humans on the ten continents is halved immediately, which is detrimental to the overall situation.
