"Yes, it's written in the report," Mike said.
The report indeed mentioned there was a Scorpion Cave. After a team entered, they were repeatedly attacked by scorpions at night. The wilderness survival expert in the team followed clues and found the scorpion's nest. It was an underground rock cave, cool and with a spring.
Only the cave was full of scorpions, and to draw water, they had to kill all the scorpions inside.
They tried using solid gasoline, hoping to burn the scorpions inside or at least drive them away.
But the number of scorpions inside far exceeded their expectations; their fuel was almost out, yet scorpions kept pouring out.
Three people were responsible for burning the Scorpion Cave; two were overwhelmed by the swarm, but one, standing farther away, escaped early and had the chance to report back to the main force.
