Quick Transmigration! The Unhinged Villainess Roams Through the Ages

[Period settings from the 1950s to the 1980s + quick transmigration + an enormous golden finger + no romance!!! There is no romance in any era!!!]

Jiang Yaoyao, the last knife seller of the 30th century, was found by her master in a bamboo grove deep in the mountains. Her master discovered a dragon-shaped jade pendant in her swaddling clothes. Having never married, she took in the infant and named her Jiang Yaoyao. Yaoyao grew up by her master's side. Her master was not strict with her, so she grew up lively and unruly, roaming the world with her. When Yaoyao was sixteen, her master was murdered. Feeling she had nothing left to live for, Yaoyao set out to die alongside her master's killer. By accident, her blood fell on the jade pendant. It vanished and became a dragon-shaped birthmark on her wrist. Just then, System 009 appeared. It could help her take revenge, but only if she transmigrated into various supporting female characters who had unfulfilled wishes or had died unjustly, and changed their fates against the odds. She would travel through different eras, earning a corresponding amount of lifespan for every mission she completed, until she achieved immortality. Jiang Yaoyao agreed.

First world: She transmigrates into a spoiled, lovesick young lady from a powerful military and political family in the 1970s.
