Kisaragi's Long-Strange Collection Notes

(The rating has just been released and will increase later.)
Two days and three months are in a year of separation, and hundreds of cities and eight ethnic groups live together in this world.
Chen Meimei, male, race: Moon, hobby: collecting strange things.
At first, he thought he had two systems: Crimson Rainbow Moon and Cold Frost Moon.
One day, he suddenly discovered that he himself could become someone else's system and control the world.
The Eighth Era, also known as the Everlasting Era, is a time when humans, witches, elves, blood descendants, ghosts, demons, and spirits jointly write a new chapter in history.
As Chen Meimei walked along the moonlit path, she was unaware that all sorts of strange things had appeared behind her.
As time went by, he acquired many titles—King in Yellow, Lord of the Strange, Heart of the Moon, and so on.
"Me? I'm just a traveler who likes to collect interesting creatures," Chen Meimei said.
