"Could it be that Mu Yanxin was the one who killed them?"
"Impossible. According to the intelligence, Mu Yanxin has just been promoted to a Heavenly Immortal. How could she possibly have the ability to kill Shadow Fifty-Seven, those three veteran Heavenly Immortals? Even if she couldn't beat them, she could still run away."
"If it's not Mu Yanxin, then who could it be?"
"I think perhaps Shadow Fifty-Seven was just unlucky and accidentally encountered a Human Clan Profound Immortal, which is why they fell."
"That's just speculation, without any evidence."
"Of course there's evidence. When Shadow Fifty-Seven fell, no trail of any culprit could be found at all, as if the cause-and-effect had vanished into thin air. This isn't something a Heavenly Immortal can accomplish."
"Should we continue to deploy assassins to kill Mu Yanxin secretly?"
