Lu Mingfei's fourth transaction came to an end, the shadow of Odin temporarily retreated, the sunshine of Kassel College was still there, but the undercurrent deep underground had already surged. The remnant soul of the Black King has not dissipated, and the lonely fate of the mixed race has never stopped for a moment.
He is the most inconspicuous E-class freshman in Kassel. He is silent, cowardly, and has low self-esteem and sensitivity. Everyone laughs at him as a waste of the mixed race, but they don't know that he has been destined to be a coffin keeper for ten thousand years. His bloodline is 99% sealed, and he hides the ancestral power to crush dragons.
During an unexpected Nibelung adventure, he passively triggered the taboo spirit, and the fire ignited, illuminating the secrets of thousands of years and the bond that the young people could not break free from. The girl from an aristocratic family who is cold on the outside and hot on the inside is his only light in the darkness; the pure and fragile silent guardian silently accompanies him through the dangers of life and death; there is also the equally lonely S-class assistant Lu Mingfei, the cold and taciturn Chu Zihang, the proud and unruly Caesar... The teenagers stand side by side to fight against the dragon crisis and the rebel conspiracy, but in the end they cannot escape the fateful judgment.
The mission of the coffin keeper is to burn himself and seal the darkness. He longs for the ordinary, but he has to shoulder everything in the end; he meets his true love, but can only look at each other across the coffin; he has the ultimate strength, but cannot exchange for the warmth around him.
The everlasting embers are protection and never-ending regret. This time, it is still the loneliness and tragedy of the Dragon Clan. The teenagers tried their best, but only got an unexpected blank space.
