Half a day passed. The Zerg had committed thirty Grade 5 Zerg; aside from the five Grade 5 Zerg still on the battlefield, all the previous Grade 5 Zerg had fallen.
After half a day of expenditure, the priests inside the Space Temples were utterly mentally exhausted and could no longer cast divine arts.
Archbishop Ambrose did not order the priests to continue casting divine arts either. Any further expenditure would consume the priests' lives. Though he was the overall commander, he could not demand that priests from temples other than the Temple of Knowledge give up their lives.
Even within Archbishop Ambrose's Temple of Knowledge, he did not want the priests to suffer excessive losses.
Priests differed from divine officials. Among divine officials, the combatants were knights who possessed bloodline power, while anyone else, even ordinary people, could become a divine official.
Priests, however, were different. Priests required spiritual talent, something scarce in God's Great World and extremely difficult to identify.
Unlike knights' bloodline talent, which could be sought among the nobility, spiritual talent was a special mutation in humans with no discernible pattern.
If a large number of priests were expended here, it would likely affect the Temple of Knowledge's daily missionary work.
After all, only priests could cast divine arts, and only divine arts could benefit the faithful.
The five Grade 5 Zerg had remained on the battlefield for over twenty minutes. Working with the Bug Tide, they had pushed the bloodline power barrier of the 130 Grade 5 Temple Knights to the verge of collapse.
"Order the Space Temples to cast an offensive divine art and kill the Grade 5 Zerg!" Archbishop Ambrose commanded helplessly.
The power of faith from the fourteen Space Temples converged. Fourteen streams of energy gathered together, transforming into enormous Divine Runes
