Those Tumultuous Years as an Undercover Villain

[Undercover agent, transmigrate, no female lead, no romantic pairing] Song Xiaoran stared at himself in utter confusion. What the heck, I transmigrated?! This is a world filled with supernatural abilities, and I have to go undercover among the villains? From the start, he was faced with a wish granted by a goddess. Song Xiaoran wished for the supernatural ability he had wanted most as a child. With this wish, he stepped through the gate to another world. He went undercover among the villains and endured eighteen years of hardship, all for the sake of national reunification. Song Xiaoran gave up so much to make that wish come true, yet even as his life faded away, he never got to see the nation united. I hope that my humble writing can pay tribute to the heroes who gave their lives for our country!!!
