I Married the Big Bad as a Substitute and Won at Life

After Jian Xi dies, he transmigrates into a book as a cannon-fodder character who shares his name.

His father doesn't love him, his mother is dead, and he's forced to marry Prince Chu as a substitute bride to bring the dying man good fortune.

Rumor has it that Prince Chu is a vicious killer who will eventually be consumed by vengeful spirits and afflicted by illness.

Jian Xi: No worries. Keep my head down, wait for Prince Chu to die, then run off with the riches of his estate.

Unexpectedly, the System chimes: "Host, Prince Chu is dying. A hug can extend his life by one day, and a kiss by three."

Jian Xi: ?

Prince Chu is the one who's dying, not me. I don't want to save a monster.

System: "If the Host chooses not to save him on your wedding night, Prince Chu will die, and the Princess Consort will be buried with him."

Jian Xi: ...

To stay alive, Jian Xi has no choice but to become a shamelessly cutesy charmer, demanding kisses and cuddles from Prince Chu every day and asking him to lift him up high.

Prince Chu is handsome and graceful, peerless in beauty. He can best a crowd of scholars with words and defend the nation with force. He was once the dream man of every young lady in the capital.

But one day, his madness flared, turning him into a jade-faced demon. Everyone feared him.

At least Prince Chu wasn't long for this world.

Everyone thought Jian Xi wouldn't last three days after marrying Prince Chu to bring him good fortune.

But three years later, not only was Prince Chu still alive, he had ascended the throne, and Jian Xi had become the new emperor's beloved husband and empress.

[Side Story]

With the Dog Food Life-Extension System's help, Jian Xi extended Prince Chu's lifespan by a full sixty years.

Now that Prince Chu was strong and healthy, with absolute power in his hands, Jian Xi decided it was time to bow out and find a place far from the capital where he could live like a wealthy local magnate.

So he packed his banknotes, left a letter, and set off with a carefree stride.

But before he could even leave the capital, the System beeped a warning: "Host, Prince Chu is turning dark. Darkening progress: 99%."

Jian Xi was determined to leave the city, but when he looked up, he saw Prince Chu staring at him with red-rimmed eyes. "Ah Xi, are you going to leave me?"

Jian Xi kissed the man on the verge of losing control. "...I just wanted to buy some land outside the city for us to retire on."
