Qi Wu nodded and reached out to touch the cold metal door.
A hoarse voice came from behind it.
The voice was low and slow, like a whisper from the depths of hell.
"You've come..."
"Challenger."
The corners of Qi Wu's mouth slowly lifted.
He pushed hard.
The door opened.
Beyond it lay absolute darkness.
A human silhouette was barely visible in the dark.
He sat in a corner, hugging his knees like an abandoned child.
But through Qi Wu's [Six Eyes], that silhouette was slowly rising to his feet.
A blood-red glow radiated from him, so dense it had nearly become tangible.
That was the power of the rule of slaughter.
Qi Wu smiled faintly.
He stepped into the darkness.
Behind him, the metal door slammed shut.
Outside the door.
The Prison Warden stood silently, staring at the tightly shut metal door.
A short while later.
He pulled three palm-sized tablets from inside his coat.
Wolf Team and Su Li drew closer to look at the devices in the old man's hands.
"These are..."
"Surveillance feeds." The old man handed each of them one. "Every cell has a miniature camera that transmits footage in real time. When I heard you were coming, I prepared two extra."
His withered finger swiped lightly across the tablet.
An image appeared on the screen.
In the darkness, two blurred figures stood facing each other.
The image was so dark that almost no details were visible.
But the next second.
The image on the screen changed abruptly.
A pair of azure eyes lit up in the darkness.
Like two brilliant stars, those eyes instantly tore through the dark.
Then another pair of eyes, blood-red this time, opened in the darkness.
Three paces apart, the two pairs of eyes stared fixedly at each other.
