*KIIIIIN!* *KIIIIIIIN!* *KIIIIIIIN!*
Like a warning sound, the sirens roared loudly, echoing around the entire map. However, the barrier no longer shrank. After it reached about a mere kilometer in diameter, it didn't shrink any further.
It was a blessing in disguise; after all, if the space shrank to a mere 100 meters, then they wouldn't be able to fight the demigod-level robots properly due to a lack of space.
"FIRE!"
After waiting for two minutes after the start, Lilith finally gave the signal to fire the lasers. The one that was boosted the most, the original, and the first copy fired together, sending an even deadlier rain to the incoming wave of monsters.
However, the same as the previous waves, more than half of the bosses remained alive and kicking. To be specific, there were a total of thirty bosses out of the fifty-one that survived. Seeing this, Lilith smiled and turned to everyone else.
