On the night I gave birth, I witnessed my sister asking the midwife to secretly exchange my child with hers. But I pretended not to know. Watching my replaced daughter being abused by her every day, I felt no emotion at all. She still raises her son carefully every day. On the day when my son was named the God of War in the Underworld, my sister came to me with her daughter who had lost her immortal bones. "Sister, the realm of reincarnation shows that the midwife secretly exchanged our child for her own selfish reasons." "Now, I want to exchange my son back." When I heard this unreasonable request, a mysterious light flashed in my eyes. "Good!"
