Just as Gong Lingyu said, the third insane spell didn't significantly affect the Obsidian Undead Corps.
They only exchanged a few blows before immediately regaining their senses.
At most, their formation became somewhat chaotic, but it didn't hurt their core.
However, Amirka was waiting for this opportunity of the enemy's chaotic formation.
Because he knew he only had one chance to strike.
Gu Xi requested him to kill two hundred Obsidian Undead to expand the battle results.
"Opportunity! Aurora Flow, attack!"
Under Amirka's command, nearly ten thousand different cavalry set off and reached the Obsidian Undead battle array in an instant.
Previously, the Obsidian Undead formation wouldn't have cared about such an attack.
The combat power of the Aurora Knight Order was inferior, and even if they had attribute blessings, so did the Undead.
No matter the cavalry's impact, their defense was still strong.
