Iron Shield City Is Garrisoned by Me-Who Could Possibly Breach It?

Iron Shield City's castle hall.

"Useless!"

There was a loud bang.

The Undead Archmage was sent flying straight out.

"Hundreds of thousands of undead soldiers."

"And you brought back only a few Monster Lords?"

"What about the other high-tier undead?"

"You abandoned all of them on the southern bank of the Boundary River."

"You lost the Legion, so why didn't you die with them?"

"Why did I ever put this useless fool in charge?"

Yin Aspect Holy Son's voice was filled with fury.

He had never expected this.

After sending the Undead Archmage south with the army,

they would suffer such heavy losses.

They had lost the undead main force outright.

How could he accept such a massive loss?

Having lost the undead main force,

there was now no main army south of Iron Shield City.

If Fang Yuan sent his main army north at this time,

Iron Shield City could be surrounded.

Iron Shield City was sturdy.

He could still summon armies from elsewhere to defend it.

But once Iron Shield City was surrounded,

the army rescuing the Fire Fox Tribe in the southeast could have its retreat cut off.

At that point, if Blue Star Lord surrounded them from both sides,

the army preparing for a decisive battle in the southeast would be certain to lose.

Once that army was defeated,

He could attack the former territory of the Beastmen Royal Capital to the northeast.

He could attack the Underground City region to the northwest.

His core territory
