### Worldbuilding
- **Spacetime Turbulence**: The continent of Teyvat and the cultivation world become quantum-entangled through the power of the Abyss. Wrapped in her Gnosis, the Raiden Shogun transmigrates through a spacetime rift and arrives in a completely unfamiliar world of cultivation.
- **Power Systems**: Raiden Ei discovers that her Electro power manifests in the cultivation world as the source of tribulation lightning. The Nascent Soul tribulations faced by cultivators turn out to be nothing more than aftershocks of the lightning she unleashes. The materials used to make magical treasures in the cultivation world also resonate in a special way with the power of the Archons.
- **Sealed Memories**: Raiden Makoto is reborn as a loose immortal, with her memories sealed inside a cherry blossom branch artifact in her dantian. The Wood Spirit sword techniques Makoto uses in battle conceal the laws of creation, perfectly complementing Raiden Ei's destructive lightning.
### Story Synopsis
- **Displaced in Time and Space**: An Abyssal upheaval opens a spacetime rift, and Raiden Ei is swept into the cultivation world while protecting Inazuma. During the transmigration, the Gnosis absorbs chaotic energy and mutates, becoming a key capable of connecting the two worlds.
- **Reunion Amid a Sea of Blood**: While exterminating demonic cultivators, Raiden Ei discovers an immortal physician being hunted. A cherry blossom branch falling from her sleeve triggers a resonance with the thunder. Gravely wounded, Makoto instinctively calls out, "Ei," yet cannot explain where her memories come from.
- **Fate Repeats Itself**: Demonic cultivators covet the source of the Chaos Azure Lotus within Makoto. This extraordinary flower, which grew in a spacetime rift, turns out to be a product of the Gnosis's mutation. Raiden Ei notices that purple lightning patterns blossom across Makoto's wounds every time she uses healing magic.
- **Memories Awaken**: During the battle against the Demon Venerable, Makoto forcibly breaks through her seal to protect Ei, bringing her memories of a past life into conflict with her present cultivation.
