Fighting for the Divine Child's Place in an ABO World

This story is also known as Days of Espionage in an ABO World Three years ago, an attack by an unknown force turned Wu Yao from an alpha into an omega. Forced to give up his former career after his sex changed, he left the police force and became a medium. Although Wu Yao has made a name for himself thanks to his identity as the "Son of God" and the help of his friend Si Chenhaoyu, he has never forgotten his search for the truth behind the attack, or for a way to become an alpha again. Though the truth is shrouded in mystery and hard to uncover, at least he has a confidant like Mu Youning by his side. Mu Youning is lively and free-spirited, with exceptional powers of observation and memory. He's the most unusual omega Wu Yao has ever met. Wu Yao secretly vows that he will become an alpha again and then marry Mu Youning. What he doesn't know is that Mu Youning is actually a mysterious agent sent by the enemy federation. Not only is he a powerful practitioner and a "saint" of a heretical faith, he can also freely change his sex between alpha and omega. Mu Youning has gone undercover beside Wu Yao to earn his trust. After Wu Yao marries the empire's third prince, Si Chenhaoyu, Mu Youning will use his good relationship with Wu Yao to become his steward and get close to the empire's intelligence core. Top: Mu Youning. Bottom: Wu Yao. On the surface, it's an OO romance, but in reality, it's an AA romance. The main plot is espionage, with everyday detective cases and social mysteries set in an ABO society. One-on-one romance, happy ending. PS: 1. This is my take on ABO, with lots of original worldbuilding. 2. It features a strong atmosphere of religion from another world. 3. The direction of technological development in this world differs from that of the real world. 4. The top is a transmigrator. The title is from his point of view, while the story is told from both perspectives. Theme: Fight for peace
