(Original God) + (Invincible) + (Multiple heroines)
During the Second Throne War, the "Sky Ice" of the outer universe merged with Teyvat's "Funeral Fire" and both were annihilated. Thousands of years later, in Liyue during the Demon God War, the battle between the Rock King Emperor and his opponents accidentally awakened the platinum demon "Chidaos" buried deep in the earth. His memory is blank, but he regards Liyue as his hometown.
Because he couldn't bear to see the war raging, he left the "Platinum Stone" transformed from his original power to protect Liyue, and then left alone and began a long wandering. His footprints are all over the Seven Kingdoms: reciting poems in the lonely city of Mondstadt, digging in the Liyue Mountains, planting cherry trees in Daowu, carving marks on the Sumeru World Tree, swimming under the water of Fontaine, and running on the plains of Nata. About a thousand years ago, he completely lost his trace.
In Liyue, the gifts he left behind were praised as "great miracles", which brought prosperity to agriculture and manufacturing, becoming a hazy and unique chapter in the myth.
Today, thousands of years later, a strange man named "Elegy" comes to Liyue Port. He has extraordinary abilities but is erratic in his behavior and unpredictable in mood and anger.
The world only knows its appearance, but they don't know that it can also shoulder more arduous missions.
