Even the Underworld Guards need to report through multiple levels to arrive, so how could there be a traitor lurking here?

A thunderous thought cleaved through the chaos in Feng Zuo's mind.

Feng Zuo suddenly realized that to accomplish all this...

A mole!

There's a traitor among them!

Moreover, they hold high positions of power and influence! They know their whereabouts.

It's even possible that it's lurking right beside the Soul Master!

"hiss--!"

Feng Zuo gasped, the excruciating pain tearing at his consciousness.

Thick fog billowed ahead, obscuring the attacker's figure.

He stared wide-eyed and looked up, but due to the pain in his soul, he couldn't see the other person's figure clearly for a moment.

Feng Zuo immediately mustered his soul power, condensed a cloud of white mist, and forcefully slapped it onto the wound to seal it.

Although the collapse has been temporarily stopped, Feng Zuo's soul has visibly dimmed considerably.

Despite his severe injuries, he maintained the composure befitting a garrison commander, and calmly shouted:

"You cowardly rat hiding your head and tail! Come out!"

A rustling sound came from the depths of the darkness ahead, followed by a delicate voice:

"Hehehe, as expected of the watchdog personally chosen by the Soul Master, it's quite tough."

Li Yu looked in the direction of the sound and saw the mist twisting and writhing in front of him, quickly condensing into a hunched figure.

With a pointed snout, long beard, and tiny green eyes that gleamed with a cunning, ghostly light, it was clearly a demonic ghost with a huge rat's head!

Li Yu: "......"

What a despicable scoundrel!

He couldn't help but turn his head, a subtle admiration in his eyes, and look at Feng Zuo beside him.

To be honest, even though Li Yu had been using the Triple Soul-Devouring Eyes, he only sensed the abnormal energy and couldn't figure out what was hidden in the shadows, but Feng Zuo saw it at a glance.

This garrison commander has amazing intuition.

However, this was the first time Li Yu had seen a demon race member transform into a ghost, and he was slightly surprised.

To everyone's surprise, Feng Zuo saw that the attacker was a rat-headed ghost, and his hatred intensified. He immediately started cursing:

"Bastard! Disgrace to humanity, traitor!"
