Humans had technology, but they were short on materials and time, unable to complete the production of large quantities of equipment.
Everything was too late.
Within a short month, more than 90% of human battleships, all large space stations, and all arms factories were completely destroyed.
Half a year later, major military bases fell one after another.
The remaining fleet was virtually non-existent.
If it were not for the battleships escaping quickly into outer space, the extinct animals ultimately would not have been able to master the space survival capabilities like the Dragonfly Fighters, and humanity's last-ditch resistance would have vanished.
