My Mother Bundled Me Up and Fed Me to the Beautiful Big Sister for Cuddles

[Two heroines, each devoted to the other! Unhinged beauty × flirtatious drama queen] (Note: The protagonist is in a passive position at the start. This isn't a nonstop wish-fulfillment story, so read with that in mind! She starts getting stronger in the early-to-middle part of the story.) Transmigrated into a world where women cultivate together as a “cultivation furnace”?! She, Lin Shiqi, can't even get started on Qi Refining from the start, yet carries within her a “Primordial Spirit Essence” that can make cultivators' realms skyrocket. In an instant, she becomes the cultivation world's “ultimate power bank,” coveted by everyone. She has no golden finger and no powerful backer. From the start, it's hell mode, with cultivators from every direction hunting her down! Until an opportunity arises and she begins to reveal her edge, meeting violence with violence... And then there's the other her, Ye Ningyu. The two souls who came from the modern world meet again, becoming each other's sword and shield in the cultivation world. “Want to lay a hand on her? You'll have to step over my dead body first!” “Want to take her spirit essence? Ask whether the sword in my hand agrees!” Who says a cultivation furnace can only be slaughtered at others' mercy? The heroine spends the early part of the story running for her life, but by the middle she dares to take on entire sects! This isn't a story where everything comes easily. The two heroines are exclusively devoted to each other. There is no harem; although other women often appear around the protagonists, there's nothing romantic going on.
