"My younger brother!" the man in his 40s yelled.
"Sorry, I couldn't help it," the man in his 30s said with a grin.
"Don't leave any traces here," the older man said.
They didn't find anything after searching for a while.
"Can't you find it here?" the older man asked.
"No, but there are other places we can search," the younger man said.
They left the area and searched elsewhere using a special method. Since Xishan Hill was not big, they soon found the broken stone.
"Look, here is their home," the older man said as he pointed at the dead bodies of the insects on the ground.
"What are these insects?" the younger man asked.
"I've never seen them before," the older man said.
Both of them squatted to study the dead insects.
"What a shame! They are all dead," the younger man said.
"Not necessarily. I believe some of them have survived," the older man said.
