MTL - Black Dragon Kingdom - Chapter 515 genetic degradation rules

After 2000 years has passed, the ruthless demon lord has just been reincarnated! But his aptitude at an academy for nurturing candidates for demon lords is, “Inept”!?

Having the capability to destroy humans, elementals, and gods, after a long period of countless wars and strife, Arnos the demon lord became sick and tired of all that and longed for a peaceful world, so he decided to reincarnate to the future.

However, what awaited him after his reincarnation is a world too used to peace that his descendants became too weak due to a huge weakening in magical powers.

Arnos enrolled in the Maou Academy established to find any students that might be the demon lord’s reincarnation, but his powers are too extraordinary that those in the academy couldn’t properly judge his powers, so he’s regarded as an “Inept student”. Being underestimated and avoided by most people there, he recruited a girl friendly to him, Misha, as his subordinate and comrade, and strives to climb to the top of the demon race hierarchy to one day reclaim his former title and status.

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!

- Description from novelbuddy

A world-famous hacker and daughter of the most powerful criminal family who ruled the international underworld for many generations is killed when their organization is annihilated in a single night.

The world froze.Literally froze. The chattering students, the falling cherry blossoms outside the window, even the dust motes in the air – all suspended in perfect stillness.“Oh wonderful hero,” a melodious voice echoed through the room. “Your world faces a terrible crisis, and you have been chosen to—”“No,” he said flatly.A pause. Then a shimmer of golden light coalesced into the form of a beautiful woman in flowing robes. She blinked at him. “I... what?”“I said no. I'm not interested in whatever quest or destiny you're selling. Pick someone else.”The goddess's perfect features creased in confusion. “But... but you've been chosen! The prophecy speaks of a warrior with a fierce spirit, one who—”“Lady, I don't care about your prophecy. I've got enough problems here without adding some fantasy world's issues to the mix. Now un-freeze time and leave me alone.”“You don't understand,” she pressed. “Our world is being ravaged by the Demon King's armies! Millions will die without—”
