Lin Jin wasn't paying attention to his looks but rather to the seemingly non-existent aura of a monster.
Lin Jin was now incredibly sensitive to the aura of monsters. Especially so after cultivating the Beastmaster Fourth Scroll, allowing him to detect even the most carefully concealed auras.
The man didn't come alone. He was following behind someone and that person didn't give off a monster's aura. However, it was clear that this person had cultivated the Beastmaster Scroll, enabling him to merge with his pet beast.
With his spiritual eye, Lin Jin could see the faint silhouette of a king cobra on that person.
Lin Jin knew about western king cobras. These were extremely poisonous and ferocious serpents that could grow up to a hundred feet long. Covered in thick scales, these powerful beasts could smash buildings and houses apart with relative ease.
