The sky was once guarded by seven star marrows. After the sky collapsed, the seven star marrows shattered and fell, turning into seven pieces of floating earth - the Seven Realms. And the one that fell into the Iron Flame Realm was broken into thousands and thousands of pieces and buried in the veins. The reason why the iron of Ash Castle is hard is because it is the blood of Star Marrow.
Lu Jin is a surveyor in Ash Castle who has been drawing mining maps for ten years. He is an orphan, honest, and afraid of getting into trouble. His only relative is the old mine manager. Until that night, he pried open the abandoned mine tunnel in District 7, pushed open the stone door that recognized him, and brought out a living star marrow from the stone room that recognized its owner - he became the first person to be selected by the star marrow in eight hundred years.
From then on, the lights turned on and the things in the darkness woke up. The footsteps approaching silently in the mine tunnel, the men in gray robes moving through the night, the deep breathing of the Star Galactus... They all followed the light of the Star Marrow and rushed towards the Castle of Ashes.
The old mine manager handed the last fire into his hands and died in front of him. Young Ah Jiu carried the sword of three generations of the family and accompanied him on the eastward journey. The city was melted overnight, ancient darkness fell, and the thousand-year-old imperial city defense formation was torn apart like paper. Two young men, with a black sword and a hot star essence, escaped from the fire and ashes and headed towards the legendary Qinglan world where "there is song in the wind".
On Qinglan's side, someone had been waiting for an eight-hundred-year-old lamp on his behalf.
