An emperor was reborn, but found himself in the belly of his father.He was reborn as the son of two male and female sons.One is the prince of the Great Imperial Kingdom (serious face worrying about his life), and the other is a medieval traveler in the magical world (blood of the water elves).This is a story of a crown prince's successful ascension to the throne; it is also a story of a time traveler who pretends to be the emperor's husband for his own sake; or a story of a reborn person who is confused every day.The author guarantees non-abuse.Known lightning points: probably the main attack; you have a child at the beginning; the logic is a little clear, and the foreshadowing is useless.
