I Teleported Into the Academy of a S*xy Game - Chapter 34:

Upon meeting the girl who would become her adopted younger sister, the duke’s daughter Christina regained memories of her previous life. Through those memories, she learned that her new sister, Mishuli, was the heroine of a certain story. And though the story depicted a Christina who abused her sister, the real Christina turned into a siscon who spoiled Mishuli to no end.

This is the love story of the 2nd brother of the Dragon Family. He is one of the most successful businessman in the capital and one of the Emperor’s favourites – he is the most eligible bachelor in the capital and every lady in town wants to marry him.

The story starts with the female lead, Ju Mu Er, a blind teacher of guzheng, who goes to pay a visit to Long Yue to ask him to build an awning on his popular business street so her friend, a flower seller, will not get wet and fall sick. Long Yue laughs at her (because he loves money and is calculative) and she makes a bet with him that she can allow him to escape from a pesky female suitor without making it obvious.

She successfully wins the bet and from then on, Long Yue constantly makes her life a trouble (since she costs him so much money)…. not realizing he is slowly falling for her.

Mirian Castrella, a student in her final year of a magical academy, unexpectedly finds herself caught in a time loop and haunted by strange dreams of the Elder Gods. Her plan had been to become an artificer to support her struggling family, but when the Akana Praediar army betrays her country in a surprise attack, everything changes. Instead, she finds herself delving into the dark secrets of the world, mastering magic, finding allies, and uncovering a vast conspiracy. However, just because the time loop can save her life doesn’t mean it can save her from everything. Mirian must navigate a dangerous world changed by the magitech revolution. Her quest to save the world from the apocalypse will lead her to battle magi and beasts, into the unfathomable underground Labyrinth, across distant lands, and into forgotten ancient ruins. Only through becoming a master arcanist who understands the true nature of the world can Mirian hope to stop the apocalypse she relives through time and time again. If she fails, everything she loves will be lost. ‍ What to expect: - Slow burn power progression - A clever protagonist who changes as the story moves from arc to arc - Expansive world-building full of complexity and secrets - A focus on magic - Intrigue and spell-flinging fights - A rotating cast of characters in each arc - Starts slow, then picks up speed

As a successful villainous BOSS, in addition to having ideas and aspirations, one must also keep in mind three points:First, grow sneakily, don't act rashly (once a villain acts rashly, they basically won't survive past three chapters).Second, you're not a good person, so be ruthless (becoming more evil will make you three times stronger, while redemption weakens you by seven times).Third, remember the two points above. The moment you forget them, your end is probably on its way.
