Xiong Delun answered "Darkness is the answer
Darkness can't be felt or smelt and neither it can be heard.
We all are scared of darkness but no matter how hard we try, it is bound to come."
Chiyou nodded in agreement and now its Xiong Delun's turn to ask a riddle
Xiong Delun asked "I have cities, but no houses,
I have mountains but no trees,
I have water but no fish.
What am I?" (94th question)
Chiyou thought about the answer as this one is tricky, a city but no houses, a mountain but no trees, a river but no fish.
What could be that thing who has this all?
But it didn't much time for Chiyou to think about the answer, he said "it must be a map.
A map has mountains, but no trees
It has rivers but no fish,
It has cities and kingdoms but no houses.
Am i right?"
"Yes you are absolutely right" Xiong Delun said with a smile.
