The beginning of a delimna

On Earth year 2023, earth is peaceful and unevenful still there are some exploration team hired for Goelogists to figure out what is in a cave that is discovered in one of the villages in the Cambodian forest. It is very concealed and deep spiraling down like it was man made with stone stairs and marsh. There several exploration teams hired and each of them has atleast 20 people because the cave has different levels. Some of the teams needs to stay to the upper levels and the rest needs to continue on down.

"It's like a beehive with one entrance and exit,right?." said one of the members of the tenth exploration team.

"We don't know that though, that's why where here." answered the Lead captain.

"We can still use signal in the upper levels but there is none anymore when we start to go down."

"Shir, have you brought extra batteries for the metal detectors. Maybe we can find some mineral loads in this cave. We don't need a lot of lighting here because of the stalactites that glows almost everywhere." ask the Lead Captain.
