"Returning from the Dust to the Ruins"
Everyone in the world knows that the Immortal Lord can help all sentient beings in a cold manner, but they don't know that he has been covered in wounds for thousands of years.
Everyone in the world is afraid that the Demon Lord will violently overwhelm the three realms, but they don't know that his obsession is limited to one person.
He takes Tao as his bones and lives up to the common people.
He regards prison as love and refuses to fulfill it.
This entanglement started in purgatory,
No reconciliation, no fulfillment, no afterlife.
All that's left is that all the dust is gone, and they return to the ruins in pairs.
Concept: From realistic fantasy
