The sword rain continually slashed down, and in just a few moments, a large number of demon beasts were annihilated in mid-air outside the city.
This scene was truly terrifying; at least thousands of demon beasts were instantly killed, greatly alleviating the pressure.
"Phew..."
Ji Chen stood atop the city wall, exhaling a long breath, his face somewhat pale.
Evidently, the sword rain just now was naturally deduced by him using the grand array.
This kind of attack was exceedingly demanding on Ji Chen himself. Even with his nine spirit veins, his spiritual power was nearly depleted.
"Everyone, continue to go outside the city to block them. I need some time to restore my spiritual power. Launching such an attack is too costly, though it seems to have been effective. You all may withdraw back into the city in an hour. By then, once my spiritual power is restored, I will launch such an attack again," Ji Chen said.
Everyone was startled, unable to voice their shock.
