The current Thousand-Year Dynasty World is no longer the Outer Dimension where monsters can be easily hunted on the first and fifteenth of each month.
Changes in the Real World also influence the Dreamland in reverse.
The original Thousand-Year Dynasty World was a dimension formed by a mix of the Netherworld and Dreamland.
With the shattering of the dreams of old and the gradual expansion of the "Heaven and Earth Bank" business, the power of the Netherworld gradually overwhelmed the Dreamland, transforming this dimension into a veritable "Place of Rebirth."
As long as a dying person leaves a mark on their soul, they will be guided to this world after death. If their relatives remember to burn paper offerings for them—of course, only Nether Banknotes issued by the Heaven and Earth Bank count—they can enjoy a period of peaceful ghost-life here.
