Exiled to the Black Tower? The Sweet Sentinel Gets Kissed to Tears by Her Yandere Sentinels

[Guide and Sentinel + Male Rivals + Chaste Male Leads + Sweet Romance + Growth-Oriented Heroine + Strong Female Lead + Love Triangle + Everyone’s Unhinged + Transmigration] She transmigrates as an F-rank guide with a terrible reputation, and is exiled to the Black Tower from the start. The original owner posed as an A-rank guide and performed fake purifications, causing multiple sentinels to die suddenly. She also drove an SSS-rank commander to a mental breakdown and murdered an S-rank guide. Now charged with grave crimes, she is escorted to the Black Tower in a livestream watched by the whole internet. Once you enter the Black Tower, death is the only way out. Fortunately, a fragment of the System transmigrates with her. She purifies mutated sentinels, unlocks her mental realm, and recovers her mental powers. The mutated beings everyone else avoids turn into rabid dogs, but to her, they’re all walking experience packs. Online, she maintains a sweet, docile persona as someone who is “adjusting well.” Offline, she secretly brings the Black Tower’s sentinels back to life, little by little. She only wants to quietly level up to the max and escape, but the more she purifies, the more possessive and obsessed the five unhinged sentinels become. The young head of the Sisyphus family reverently kisses her eyes. “Please choose me. I’ve saved up a lot of money. Both my money and I belong to you.” The First Commander’s tentacles coil around her waist and refuse to let go. His gloomy eyes lower, revealing sharp little tiger teeth. “I’m your favorite, aren’t I?” The refined, elegant man from the East awkwardly bites his own clothing and tries to seduce her. “Please don’t leave me behind.” Her archenemy wakes from a breakdown, and the first person he looks for is her... She hurriedly calls for help from the System, but the pretty young man grabs and binds her instead. “I told you from the beginning to watch out for those bad guys!” “People who don’t listen to the System deserve to be punished.” An Yu looks helpless. I just want to live a quiet life. Why are you all clinging to me?
