The Cheeky Viper.

"Yes, I can speak. Are you afraid?" It grinned and asked him.

He replied confidently, "I am not afraid. Your intelligence makes no difference. Power is power. There is no need to be afraid of a weakling that can speak. I have met a lot of them today. In fact, I killed tens of thousands of them at once."

He is not afraid of the Viper but he has more reasons to be careful and cautious with it. It is not encouraging that it has intelligence. The dragon didn't have intelligence but it was able to use skills. He knew to expect skills from a monster that is rank 10 but the intelligence caught him off guard. It having intelligence could mean a lot of things that he doesn't know so he will be extra cautious with the Viper.
