Reversing this to deduce, it could also be understood as—before Morgan falls, there shouldn't be any major incidents with the Silver-Crowned Dragon.
After all, this is a self-rescue plan arranged by the Silver-Crowned Dragon itself.
The Silver-Crowned Dragon would not set a self-rescue plan to take place after its own death.
Sherlock understood: "You're saying, use Morgan as a status coordinate?"
"Exactly."
Aiwass happily confirmed: "As expected, you understand me!"
As long as Morgan doesn't become the Celestial Marshal, it means the Silver-Crowned Dragon's condition is still good. If the Silver-Crowned Dragon still has enough sanity, it will hand over its position to Morgan before it is completely corrupted... just as the Beast Master once handed over his position to the Eternal Self.
And if the Silver-Crowned Dragon has already been corrupted, it naturally wouldn't let itself fall. At that time, Morgan would be dragged down as a sacrifice of the Ring of Ouroboros.
