My Dream Goddess Became an Empress After I Possessed Her Soul?

A vivid recollection of the path to sainthood. I will become the sole salvation of this chapter in history.

The Empress? Was she the only thing I had to cling to across ten thousand years, or was she part of a conspiracy by those who call themselves “immortals”? At last, I seized my one chance: to walk the path to sainthood once more. If I can find the “Heart of Time and Space,” I can return to that time. And now, the story begins...

A disaster during college sent the protagonist and his classmates' souls into the chaotic Great Rebellion Dynasty. Complete their missions, and they could return to the real world. What? The mission of the department beauty I've had a crush on for three years is to become the Empress of the Great Rou Kingdom, while the mission my damn System gave me is... to kill the Empress and seize the throne?

I gave the one chance to survive to the woman I loved, while my own soul became an “ 역사-saving device” for immortals.

My soul transmigrated into the eldest son of the Marquis of Wu. My family had countless enemies, and I fought with everything I had to turn the tables against the odds. All I got was the “certificate of eternal life” they believed billions of people longed for.

But I will shatter all of this with my own hands. The laws of the world? Just a game played by a bunch of old monsters...
