The Cannon Fodder Female Supporting Character’s Technological Path to Immortality

[Strong heroine + space + sweet romance + both leads are devoted to each other] Song Li, a research superstar, works herself to death after pulling an all-nighter and transmigrates into Su Wanyue, a cannon-fodder supporting female character with a tragic fate.

In the original story, Su Wanyue is honest and easy to fool. She treats the heroine as her best friend, argues with other supporting characters for her, acts as her shield, and becomes a tool for the heroine's fights with her rivals. Once her usefulness is drained, she dies miserably.

A tool? Su Wanyue scoffs. What's fun about being a tool when research is so much more interesting? She still hasn't achieved fully automated pill production, improved her flying sword's speed by five points, built a spiritual-energy gun, built spiritual-energy shells, or made an aerial car... She's busy.

Other people fight with techniques and cultivation. Su Wanyue fights by launching a barrage of shells. The heroine, the supporting women, all of them can get out of her way. Don't disturb her research.

PS: There is a male lead. No melodrama, no other woman. The heroine focuses on her career, and the hero is her biggest supporter.
