Longevity begins with Orion

In general,

Single ghost: between the fifth and fourth grades

Double~Multiple ghosts: between fourth grade and third grade

Garden of Strange Beasts, Palace of Ultimate Bliss, and Mortuary Clothes Room: between the third and second grades

High-level props in the ghost realm will be processed one level lower.

That is to say,

Single ghost props are equivalent to those between the sixth and fifth grades, so the sixth grade can be used, but the fifth grade cannot.

Double~Multi-ghost props are equivalent to those between the fifth and fourth grades, so the fifth grade can be used, but the fourth grade cannot be used.

The props at the Garden of Wonderful Beasts, Palace of Paradise, and Mortal Clothes Room are equivalent to those between the fourth and third grades, so the fourth grade can be used, but the third grade cannot.

"Yin makeup rouge" is a single ghost prop, so it can only be used on the sixth grade, but not the fifth grade.

"A Thousand Miles of Thread" is a high-end prop of Paradise Palace, so it can also be used on fifth-grade items, and he can also use it himself.
