Scaring Demon Ancestor Jun

'So it was really him who peered through the whole of Beltran City using an unknown technique. He doesn't look strong at all based on his physical appearance, but he has this kind of unworldly air that makes him mysterious and unfathomable. Let me test this human. Hmph!' Demon Ancestor Jun felt unnerved by Jiu Shen's calm and expressionless face. He wanted to see what this human was hiding beneath his indifferent exterior. 

The old demon released his aura without constraint, making the air around him tremble vigorously. The demon soldiers looking at this scene felt dread in their hearts as they watched the old demon's display of prowess. The four Demon Lords behind the Demon Ancestor glanced at the old man in worship and fear.
