MTL - Mermaid Effect - Chapter 2

Vainqueur Knightsbane is your average dragon: a giant, fire-breathing lizard who loves to take naps on his golden hoard, kidnap princesses for fun, and make the life of adventurers miserable. Vainqueur's only pleasure in life is to watch his treasure get bigger, one coin at a time.

So when a would-be thief turned unwilling minion tells him about "classes," "levels," and "quests," Vainqueur wonders if maybe, just maybe, he should consider a career change.

After all, why bother hunting monsters for free when you can get paid for it?

Linky transmigrated to the Magical Land and became the third young master of a noble family. Just when he thought it was time for him to enjoy a life of luxury.

He was sent out for the family’s tribulation, and had to set off to the “Land of Death”

— Black Wind Castle! Here, dark elves, frenzied orcs, and blood-thirsty dragons were regular occurrences! Everyone thought that Linky would surely die, and had even prepared to collect his body.

But just then, Linky awakened the [Super Gourmet System]. As such, things changed.

The Elf Queen loved his fruit salad, while the Orc Saint couldn’t get enough of his grilled steak. The Sorcerer of the Holy Palace couldn’t live a day without the “Linky Brand” whiskey.

Even the Vampire Prince Nikolas would sacrifice anything to get a long-term order of Linky’s fresh blood coffee.

Until one day, when a gargantuan dragon that blocked out the skies came to his door…

Lou Yao Yao wasted her life fighting over a man, only to find out he wasn’t worth it in the end. Because of this man, she accidentally killed her rival in love, and even ruined the man who had always been watching over her.

Getting reborn as her 20 year old self, there is still time to fix everything. Lou Yao Yao decided to live as a genuine vicious woman. After getting her hands on the loyal like-a-dog man, she would show that cheating couple what pure loving affection looked like.
