"Since you came here, I take it you have some ideas?" Dean stared at Crowley. He knew full well how cunning this demon was, so he asked without any courtesy.
"Yes." Crowley did not deny it, instead nodding readily. "If you still don't have any solution, I can offer a suggestion. It's just that..."
He looked toward Sam. Sam froze, while a bad feeling instantly rose in Dean's heart.
Crowley looked expectant as he sized Sam up. "Sam, you possess demon blood. You are also Lucifer's destined human vessel, a weapon chosen by the power of Hell."
"There is only one way to trap Lucifer: agree to become his vessel. The instant his soul enters your body, lead him into the opened Cage with you, then quickly seal it. At that point, Lucifer will be sealed inside the Cage."
At this point, Crowley shifted his tone. "Of course, that would also mean entering the Cage alongside Lucifer. The consequences would be far more terrifying than death, because your soul would not be torn apart. Lonely within the Cage, Lucifer would torture your soul without end. That kind of pain is unimaginable."
By the time Crowley finished, both Dean and Sam had changed expressions.
Dean in particular lunged forward at once, ready to grab Crowley by the collar. Wasn't this method asking Sam to sacrifice himself?
But Sam stopped him.
After his gaze shifted back and forth, Sam finally made up his mind. "I'm willing to do it," he said in a low voice.
Wu Heng watched everything from the side. If they really did as Crowley said, how would this be any different from the original plot? Why had he gone through so much trouble to move the Cage here?
Crowley raised both hands, signaling Dean not to get worked
