A Dark Door of Destiny

In Yu Miaomiao's world, a strange black door was born out of thin air, following it like a shadow. She had long been accustomed to this strange phenomenon, until the disaster struck. The monsters in the office building were searching and killing the living people floor by floor. Lin Wan, who was covered in blood, desperately tried to find her. In desperation, the two of them could only open the strange black door engraved with gilded patterns. It's unclear whether this mysterious door saved them from the brink of despair, or whether it was their appearance that awakened and redeemed this door that had been alone for a long time.
