After leaving the aisle Dudian saw Peter using a flute-like pipe to whistle. A black crow flew afterwards, he wrote a message with the pen and it carried the message away.
"The area within the giant wall is to huge so consortiums have raised crows for carrying message. If you are in hurry to report something you can also use them." Peter explained with smile.
"Are not they afraid of radiation?" asked Dudian.
"This crows are not only smart but also resistant to radiation. They can also be used in radiation area while hunting too. " Peter laughed.
Dudian knew that crows had mutated to something unique which was resistant to radiation.
Peter accompanied Dudian. He saw the huge storage bag on Dudian's back: "Even if you are a hunter you haven't forgotten to scavenge various materials. It should not be as profitable as killing those beast.?"
