*Gulp*
Karna broke out in a cold sweat hearing the words of Durvasa, Through the words he said made it look like he was requesting him but Karna can tell it was far from the truth.
This is no way of request. This is a naked threat, If he did not answer his questions of his, Then he better be ready for getting some high-class custom-made curse for him as that would happen.
"Please Rishi, Ask If I can, I will answer it."
Karna gave in, He did not dare to mess with someone who did not talk normally at all, Vidur and Bhishma were easy to trick because they were the ones who are following the rules they are for themselves.
It's easy to trick someone who has their own rules, You just have to bind them in their own words and they will fall for your tricks. This is a tried and tested technique from the ages.
