Dragonborn: the Last of the Nibelungs

In the last Nibelung, facing the resurrected Black King, The little devil Lu Mingze sacrificed himself to give Lu Mingfei his final voice, allowing him to return to the road of becoming a king! "This time, brother, you must save your beloved girl!" "It's just that this time, I will no longer accompany you!" (PS: This book re-travels the Dragon Clan timeline, but will create two other kings)
