The life on seven lands

Its 2072,Everything that was on Earth is over, but people still live here.after a nuclear attack on whole earth...
its no more earth,its only seven lands where people struggling to live.
This attack brought the whole earth to the brink of destruction, but after the attack, whoever accidentally breathed in it only for a short time without any filter Some part of his sense was greatly increased.This power is only the senses that are your weakest sense.
Despite this, if anyone breathes it for a long time, then that air only kills it.
Raman is here accidentally from some other time And he is unable to guess anything, so which sense will increase for him.
Now water is not so easy on seven lands and Raman is thirsty, so where will the search for water take him......or the search will become a great journey.
