Just as Gong Lingyu had said, the third spell, Mind-Madness, did not have much effect on the Obsidian Undead Troop.
They merely exchanged a slash with one another before immediately coming to their senses.
At most, their formation had become somewhat disorderly; it had not damaged their foundations.
But this chance to throw the enemy formation into disarray was exactly what Amirka wanted.
Because he knew he had only one chance to strike.
The reason Gu Xi had demanded that he kill two hundred Obsidian Undead was to expand their gains.
"An opportunity! Aurora Flow, charge!"
At Amirka's command, nearly ten thousand cavalrymen of various kinds set off at once, reaching the Obsidian Undead battle formation in an instant.
If this had happened before, the Obsidian Undead formation would not have cared about such an attack at all.
The Aurora Knight Corps was weaker than them. So what if it had attribute boosts? They had attribute boosts as well.
So what if there was a cavalry charge? Their defenses were still extremely strong.
At most, their movement speed had slowed somewhat. Taking this hit from the cavalry would practically be like taking no damage at all.
But the cavalry only had one chance to charge.
If they wanted to charge again, they would have to withdraw one or two hundred meters and build up speed again.
That meant that before the spell on the Obsidian Undead was dispelled, they could charge at most three or four times.
So what if some Obsidian Undead died during those charges?
Their losses would not exceed a thousand.
Leader Nu was extremely confident in this calculation.
In his mind, when had he ever fought a battle without losing that many troops?
Do not let his high level or status as a leader fool you.
