"The moon is hollow."
Could there be anything more absurd?
I looked at Pandora incredulously, seeking a more definite answer, but she nodded affirmatively, "Brother, the inside of the moon is empty."
"This is ridiculous," I shrugged and turned to Sandora, "Did you guys have a habit of hollowing out moons to build bases in them back then?"
However, Sandora's reaction was a bit strange. She ignored my question and furrowed her brow in thought.
"What's wrong, Sandora?"
"Nothing much…" Sandora shook her head, her brow not quite relaxing, "Maybe I'm just overthinking it… If there was a gigantic base established inside the moon, then the events that happened in this star system seventy thousand years ago might be a bit complicated. Pandora, did you find the cutoff layer?"
"We discovered four suspected entrance points, the closest one is about a kilometer from our current location."
