[Reverse harem sentinel-guide romance, love triangle drama, unhinged characters, growing heroine]
Yu Qingdai woke up one day to discover she had transmigrated into a sentinel-guide world, where she had become a C-rank control-type guide. To support herself, she had no choice but to find a job. When she discovered that the Black Tower offered excellent pay and benefits, she applied. There, she worked diligently, interacting with different team members every day, constantly honing her skills and earning a living. But the Black Tower's sentinels began looking at her differently, trying all sorts of ways to seduce her every day. How could an ordinary young woman resist such temptation?
The heroine is a triple-type guide, and her spirit form is an Imperial cobra. She's strong and grows stronger over time, and all the male leads are virgins.
