"Only twenty thousand prestige points left." Wen Ping glanced at his prestige balance, determined to first build the Celestial Control Array.
Although it would reduce the effectiveness by seventy percent when defending against a Primordial Vast Realm powerhouse, it was still better than just opening the gates to let them wander freely.
"If it's an ordinary Primordial Vast Realm, how long can the Celestial Control Array resist?"
The system responded, "If a Primordial Vast Realm powerhouse continuously attacks the Celestial Control Array, it can hold out for a maximum of one month."
"It's unlikely that any Primordial Vast Realm powerhouse would be so idle as to attack the Celestial Control Array nonstop for a month." Knowing this result, Wen Ping felt a lot more at ease.
Next, Wen Ping surveyed the other world-class structures. Apart from the Celestial Control Array, the cheapest was the Colorless Mountain.
