A high-pitched alarm rang, alerting the entire base.
"!!!"
"Enemy!"
They scrambled, wondering where the enemy was.
"What's going on?"
"Where are the enemies?"
"Have we been infiltrated?"
The soldiers were confused. There was no ruckus, so they wondered if it was just a false alarm.
Bam!
Suddenly, the roof of the building that was supposed to contain the tower collapsed.
"!!!" All the soldiers couldn't help but widen their eyes. They immediately rushed to the building. "Enemy!"
"What the hell?"
"How can the enemy infiltrate this deep without anyone noticing?"
They panicked, wondering if there was a hole in their defense. For the last few months, they had been strengthening their defense, so they didn't expect that all that reinforcement was useless.
…
Underworld.
The same alarm rang across the base, alerting everyone that someone had infiltrated their base or the tower.
Because nothing happened in their base, they thought that the enemies infiltrated from the surface.
