Starry Sky Fairy and Demon

In the dark and cold universe, above the starry sky, an ancient bronze coffin with Taoist patterns all over its body stands in the starry sky, as if it was born in the grand mist, in the chaos. No one knows its origin, and what exists in the coffin, wandering in the endless chaos and the long river of time. Until one day, nine ten-thousand-meter-long five-clawed golden dragons pulled the ancient bronze coffin and disappeared into the chaos. Hundreds of millions of years later, a young man in the world stood in the starry sky, looking at the ancient bronze coffin in his mind, but he still couldn't understand what was in the ancient coffin?
