Low Martial Arts: From Scientific Cultivation to the Unity of Corpse and Soul

[Transmigration + scientific cultivation + science student + no CP] Office worker Jiang Li was killed by a meteorite and transmigrated into the role of Jiang Menglan, the female side character in an engagement-breaking plot. The good news: This isn't a world of ordinary mortals. She can cultivate immortality! The bad news: Her true energy can only strengthen the body, and her lifespan is about the same as an ordinary mortal's? As a science student, she decides to use the scientific method to figure out how to cultivate. Someone disturbs her peaceful cultivation? She pulls out a pistol. "Sir, times have changed." Ascended to the wrong world? No problem. She's already a Nascent Soul powerhouse. The cultivators of the spirit realm are terrifying? Don't panic, she's got a nuclear bomb! Cultivation stages: Qi Refining, Foundation Establishment, Golden Core, Nascent Soul, Deity Transformation, Void Refinement, Body Integration, Tribulation Transcendence, and Mahayana. [Note: The heroine has a ton of side hustles and seems very much like a demonic cultivator.] One more note: Don't mix up the heroine's name with those of her external incarnations. [The heroine's only name: Jiang Menglan] [Names of her external incarnations: Jiang Lan, Li Feiyu, Wang Defa, Jiang Jiude, Jiang Lan, Jiang Bagua, Jiang Menglan, Liao Xinghui, Jiang Buling, Jiang Qi, Jiang Lu, Jiang Wu, Jiang Si, Jiang San, Jiang Er, Jiang Yi…]
