Tu Xiao'an instantly felt an unprecedented pressure. The aura emanating from the old man felt extremely, extremely dangerous.
He might even be an opponent he couldn't possibly defeat.
Experts don't have to trade blows to know who is stronger.
To put it in perspective using the Rank Three Demon Spirits Tu Xiao'an had encountered, the Rank Three Snake Flood Dragon had only just entered Rank 3 and wasn't particularly strong. His Insight had revealed its data instantly.
The Bull Demon King was at Level 32, having been a Rank 3 for many years. He was considered very strong, yet Tu Xiao'an could still use his Insight on him.
However, Tu Xiao'an couldn't get a single shred of data from this Vice Dean. Based on the strength of the aura he was releasing, Tu Xiao'an secretly speculated, 'He must be Level 35 or higher.'
He figured that his Conscious Insight became useless and unable to scan anyone whose strength reached about Level 35.
