Zi Yusen passed through a book of O-masochism, and his identity was the villain's tool who tortured the male protagonist.
The protagonist, Mu Li, is an omega pretending to be an alpha. He was originally the marshal of the Galactic Empire. Once aliens invaded, the empire fell apart and Mu Li was captured. The new emperor crippled his mental power, humiliated and tortured him in every possible way, and forced him to marry a notorious human traitor, a sexually abusive Beta.
Everyone thought Mu Li was finished, until five years later, Mu Li contacted the human rebels, worked together internally and externally to overthrow the tyranny, and tortured the dude who had humiliated him for five years to death for three days and three nights.
... Zi Yusen transformed into this old man who died miserably.
——————————
For the sake of his own life, he wished he could have Mu Li imprisoned and protect him in front of the new emperor. He also tried every means to contact the rebels, worked hard to clear his name, and devoted himself to portraying himself as a heroic undercover image who endured humiliation, endured hardships, and endured hardships!
Five years later, the human empire was restored, and Zi Yusen cried with joy. He could finally retire and live the life he longed for!
Unexpectedly, his "wife" came to bed in the middle of the night, her eyes filled with crazy tears of lost things.
Zi Yusen: "??? Wait a minute, aren't you an omega???"
Mu Li: "You will know after you try it."
