MTL - HacKer - Chapter 1421 No. 4 and No. 6: Change temperature!

I ended up transmigrating as a third-rate extra in a game I like, but worst of all this character has already fallen and been disowned.

I have no ambitions. I just want to graduate, but the world won’t let me.

The ending of fairy tales is usually a happy ending of the hero and heroine. As for the supporting characters, who will care about their happiness? Having such a bad thought one day, they suddenly turn dark. They want to revolt, and they don’t want to be the main couple’s stepping stone for their ‘True love’ again. Oh my god! What’s about the plot? What kind of story will it play out with a character like this? Can it still run smoothly? The hero and the heroine are going to be crippled by the supporting character!!!!! Well, there’s actually a project to save the plot from it. By nipping the bud of all evil thoughts from them, and let the hero and heroine live together in happiness. The named of this project is ‘To save the supporting character’. All executors must dutifully do their work, and as for the mean to achieve it? Oh! That’s not worth mentioning~

No matter whether it is a white cat or black cat, if that cat can catch a mouse then it is a good cat.

When MC was reliving a picture of a goddess, he died. Only meet the goddess, but instead of torturing him to eternity, she gives him wishes. And make him reincarnated in the Overlord world.As the name suggested, this is multiverse Fan fiction, that means MC will travel through different world like Marvel, DC, High School DXD, My vampire Diaries (may be) , Demon Slayer, etc.first world: Overlord (Chapter: 1—60)second World: Highschool DXD (Chapter: 60—215)Third World: Demon Slayer(Chapter: 216—)Fourth World: New World (Overlord)There will be a harem, no NTR or stuff.Some of you might dislike the Yggdrisil arc as it is a bit of AU and MC talk a lot. But it is only in this arc on world travel that I will tone down his unnecessary internal monologue.I am not a professional writer, and I have no deep experience in writing, so please ignore my grammar mistakes and such. I also took some inspiration from other fan fiction.It would be a great help if you could donate your power stone to me.
