The group looked into the sandstone hallway. It was so long you couldn't see anything at the end.
"I think I should make an iron door at the entrance to our cave!" Michael exclaimed and ran to the entrance to place the door.
Liam looked at Eve. "You really think a possessed person is causing this?" he said. "For a scientist, that's a stupid answer."
Eve was sad. "Yeah, you're right." she said.
"Finished the door!" Michael called out.
Liam, Eve, and the pets wandered over to the entrance. There was an iron door with lever above it on the inside.
"What's the point of a door?" Eve asked. "We're just hiding here until the apocalypse ends. If it ever ends."
All of a sudden there was a loud knock at the door.
"Liam! Block off the entrance to Minelantis!" Eve exclaimed.
Liam ran over to the entrance and blocked the entrance with some smooth stone so it looked natural. You couldn't tell an ancient ruin was behind it now. Michael pulled the lever to open the door. A crowd of people were angrily looking at him.
"Hey guys!" Michael welcomed them. "Shouldn't you all be hiding in your cave systems?"
"There isn't another cave system around here!" Michael's ex-best friend Jack called out. "We want to go in yours!"
Michael sighed. This was not an easy decision. He either had to let everybody in so the place would be very crowded or shoo them away so they burn to death outside. Letting everybody in would mean letting in Jack. He wants to be a criminal mastermind, which is why they're not friends anymore. He's fat, always wears a gray outfit, and he has a big moustache. He always had a menacing look on his face and wore black shoes. He looked very evil.
Michael finally spoke. "I'm going to regret this when we're crowded and running out of air but..." He paused. "Come on in!" he finally croaked out.
The crowd of people crammed into the cave, and when Michael finally closed the door, there was almost no room in the cave.
"It's too crowded in here!" Liam complained. "Someone is going to have to leave!"
"Well..." Eve started. "The world of the future will need science to make new discoveries. I'm in!"
"The world of the future needs a circuitry master! I'm in!" Michael exclaimed happily.
"Wait a minute!" Liam yelled. The crowd of people calmed down and became silent. "You know one thing the world of the future doesn't need? Criminal masterminds who try to steal people's tools and weapons! That's you, Jack!" he screamed, pointing at Jack. "If anyone in this room were to die, it should be him!"
Jack was a bit upset, but his life was very unhappy, failing miserably every time he tried to steal something. "Well..." he mumbled. "Bye everybody. I'll just go outside and... die then." It was a reaction kind of unusual for a criminal. He pulled the lever, exited, and Michael pulled the lever to close the door again.
Suddenly someone in the room started mining a staircase in the wall, and after 20 layers deeper, started mining a huge room. Everybody in the cave started cramming into the area the person was digging out. They knew what the person was thinking.
"Quick!" Michael whispered. "Let's sneak over to Minelantis while we have the chance!"
The group secretly dug into the ruin and placed the blocks back, while everybody was still trying to get in the room the person was mining.
