The Fifth Junior Sister Is Too Stupid, She Goes Crazy When Others Are Cultivating Immortals

A genius military arsenal developer in the 21st century traveled through time and became a cannon fodder female supporting character with the same name in a fairy tale. Originally with poor qualifications, they relied on spending money to join the Daixing Sect as their direct disciples. They seemed to be a group of prosperous people, but in fact they were miserable. The master and fellow apprentices are both mentally retarded, and the main theme is a heroine who can't tell right from wrong, and there's also a covetous heroine who doesn't like her at all times. Bai Yan said that I don't want to stay in this sect anymore, whoever is responsible for this unlucky descendant will be judged! What, even if you leave the sect, you can't live in peace? Even her new senior brothers and sisters were targeted? Don't worry, as the saying goes, it's never too late for a gentleman to seek revenge. Let's talk after I build the fighter jets and tanks? In a word, as long as I don't act according to common sense, no one can do anything to me!
