Raidorl Seiken Senki - Chapter 27: Declaration Of War.

After being killed, Xu Turan was given a system and got pulled into a certain thriller romance novel. There, she became the crucial female supporting role who seeks death. However, on the first day of transmigrating, her system was urgently recalled for repair as it was aging.

As their farewell was imminent, the system was worried about its new host so it repeatedly reminded Xu Turan: [Your role is to be a supporting character who is always seeking death. You do know what that means, right?]

Xu Turan recalled her rich experience of doing just that in her previous life and she replied affirmatively with absolute confidence.

So the system withdrew with its mind at ease.

After a few days, the system that had been away for repair finally returned. When it looked at the situation, it almost malfunctioned: [What are you doing?!!]

Xu Turan, who was busy arguing with the Evil God, answered without thinking, “I’m doing what you asked me to do – trying to find ways to die.]

System: […?!]

A god of a different world had abruptly appeared in my classroom and semi-forcibly summoned the entire class to his world.ーーーーexcept for me, Kamiya Yato.

Seven billion humans living on the Earth time-traveled together after they had woken up one morning. They all heard a synthesized female voice.

Lian Xi transmigrated into an ancient tyrant’s general essay and became the female supporting role of a wealthy family of the same name.
The female supporting actress has a beautiful appearance and a prominent family background, but she was forcibly demoted by the plot. Whenever the male and female protagonists need emotionally, she will be pulled out to do things, and she will be slapped in the face again and again, a proper tool person.
Lianxi: I’m sorry, I have money, looks, and figure. Whoever loves this wise female partner will be the one, and I will say goodbye.
System: If you don’t complete the [Vicious Female Supporting Team] quest, you will die.
Designated line 1: [You are also worthy of me to grab a man]
Lian Xi was driving a Ferrari, and a drifter got off the car and sneered at the boss who was confronting the villain: “You are also worthy of me to grab a man.”
President: ? ?
Opposition:  …
Designated line 2: [Look in the mirror without urinating]
Lian Xi rushed over with a group of bodyguards and pushed away the boss who was hugging the heroine and kissing him: “Be a hooligan, don’t pee and look in the mirror!”
President: ? ? ?
Mistress:  …
Designated line three: [You think you can beat me]
Lian Xi was mad, so he directly bought the Oriental Pearl LED advertising screen and played it on a loop: “Oh, Mr. Ba, do you think you can beat me?”
President: ? ? ? ?
After finally crushing the original male protagonist, Lian Xi completed the mission of the vicious female supporting role.
System: Congratulations to the host, the master mode has been successfully activated.
Lianxi: Huh?
She took a meaningful look at the villain with eight-pack abs lying on her bed, lit a cigarette afterwards, and threw 500 million: “Sign this contract and let me sleep for five years until I become pregnant with an heir.”
The villain laughed so innocently: “Want to fuck me?”
The original hostess: We always want you to look down on you, don’t know what to do!
