The Demon Mist of Silence was such a Power of Death.
It maintained everything in its vicinity in its original state, so that beings hidden within the Demon Mist remained undetected by the outside world.
When the three Demon Gods were escorting him and Satan to cell 317, the moment the Demon Mist was released, a dual illusion emerged:
The other Satan sitting on the bed did not notice any movement at the door.
The three Demon Gods at the door did not see the Satan on the bed.
Both parties perfectly missed each other.
——However, about a few minutes later, Satan suddenly looked up towards the door.
The iron door opened again.
A man dressed in a deep yellow robe walked in and said, "Boss, I'm back."
"Where are the others?" Satan asked.
"It seems they all went to find ways to enhance their character's strength," the man said.
"Then why did you come back?"
"I've caught two prisoners."
"Prisoners?"
