Ye Tian had people defend the entrances to Imperial City, stationing heavy guards at the four city gates, and anyone entering or exiting had to be scrutinized.
He knew that this approach could only stop some ordinary people, if someone flew over from the sky, or burrowed underground or into sewer pits, those kinds of defenses, akin to trying to stop rats, were impenetrable.
Ye Tian could only cover the entire Imperial City with his Divine Sense all day long, so he could not leave the city to prevent terrorists from entering.
In a place unknown to Ye Tian, a city 500 kilometers away from the Imperial City, a group of people dressed in black was gathered in a secret chamber below it.
They were being led by someone, carrying out a large-scale conspiracy.
Previously, they had considered the Imperial City, but upon learning that Ye Tian had stationed heavy troops there, they thought of another way to lure Ye Tian out.
