Mu Xinyu is a cannon-fodder character in a transmigration novel, appearing in fewer than a hundred words in the entire story. He is the youngest son of the empire's marshal and its princess, and went missing as a child. He's merely a plot device to introduce the transmigrated shou to the story's righteous gong, the imperial crown prince.
But now Mu Xinyu has transmigrated back! One moment, he was exploring a secret realm with his beloved husband and their disciples. He slipped and fell into a lake, and when he surfaced, the world before him had changed! Then he saw his elderly father, mother, and three older brothers, and was utterly dumbfounded. He was happy to be back, of course, but he'd vanished just like that. How worried must his beloved husband be?
The little mermaid from the marshal's family has been found! The mermaid's strange disappearance and even stranger return quickly became the talk of the city. No one knew where he'd gone, and he didn't even know how to use a brain-computer. How quaint and backward. Later, people learned that the little mermaid was carrying an egg from some unknown bastard, and looked down on him even more. The mermaids raised in the marshal's home were so much better, so noble.
Later, the bastard sliced open the sky above the city with a single stroke of his sword. Leading a vast fleet of exquisite immortal ships, he crossed the spatial barrier and arrived, his immense pressure so overwhelming that no one in the city could lift their head.
The bastard reached out to Mu Xinyu. "Xinxin, let's go home."
"No." Mu Xinyu waved his hand. "You have to come meet my parents first."
Thump. The man fell off his sword.
