A terrifying aura spread out; it was the presence of a Level 9 Ghost Emperor.
This aura sent chills down the spines of the Contractors, leaving them utterly shocked.
Especially the Contract Demons within the Contractors, they were even more sensitive and afraid of the Ghost Emperor's presence.
"Ghost Emperor, that's a Ghost Emperor!"
"Level 9 Ghost Emperor, my God! He's actually attacking the Ancient Castle."
"Will the castle be breached? Is it safe?"
The Contractors began to panic.
Although the highest among them was a Level 6 Contractor, the lowest was still a Level 3 Contractor.
But the most powerful they had ever encountered was a Level 8 Ghost King; they had never seen a Ghost Emperor before.
Nor had they ever seen such a gigantic and abnormal creature.
Soon they also saw that beside the giant monster, there were many other creatures with powerful and terrifying presences.
"Sen...Sentry, there are so many monsters, and even a Ghost Emperor, can the castle stop them?"
