The treasure seekers
Once there were three seekers, Peter, John, and Rose, who found a map and recogniced that there was hidden treasure in a cave near a cemetery.
The next day, they brought some tools to explore the cave. As they slowly walked deeper into the cave, it became darker and cooler inside. Rose was getting uneasy and asked Peter “why don’t you switch on your flashlight?”
Peter agreed. When the flashlight was on, they found a huge gray object standing right in front of them. They were astonished and frightened. John went up and carefully examined the object. He then said “it’s a stone casket”
“why don’t we see what’s inside?” suggested Rose.
Everyone agreed. Peter and John used crowbars to force open the casket cover while Rose pushed the cover to the side. Suddenly it slupped and feel to the ground with a loud bang.
They got a temble shock and took a few steps backyard. All of them nearly fell on the ground because a preserved corpse was found inside. They saw plenty of jewelery and exotic paintings buried with corpse.
While they were examining the contents of the casket., Rose fell on the ground. She shouted, “SCRAM” then, immediately rushed to the exit followed by Peter, John was the last. Before he reached the exit, it was completely sealed off by falling rocks. He was trapped.
What suddenly occured was too much for John to handle. He knelt down and solemnly prayed to the deceased that if the got out of the cave alive, he would keep this place a secret and never retrun to disturb it.
A short while later, he shaw firefly fluttering from the casket in the opposite direction of the blocked exit. John followed the firefly step by step. He saw some distance away, some dim light coming from the end of the cave. He immediately removed some rocks. To this surprise, it was another exit, and the dim light was moonlight outside the cave. He knelt again to thank the spirit
