Reborn Demon Slayer in the Edo Period to Save Everyone!

[Invincible+Orange+Taoism+Two heroines] Murong Yi, a proud daughter of heaven who is rarely seen in a thousand years in Tianshi Mountain. At the age of six he worshiped the mountain, at the age of eight he made talismans, at the age of ten he wielded a sword, at the age of twelve he raised his hand and palmed thunder. At the age of eighteen he could not bear the daily boring life on the mountain and secretly ran down the mountain. I encounter an out-of-control 100-ton king by chance on the roadside, and I can't defeat it even though I try my best! When she opened her eyes again, a particularly handsome man with red eyes looked at her. Feeling that the other party was not a living person, he was so angry that he raised his hand and fired a thunderbolt. Wuhan watched the extremely fast lightning destroy his extremely powerful body, and without hesitation, he split a piece of his scalp and ran away. Except for the red-haired man who kept asking him what he did with human life, he swore. This was the second time he was closest to death, even more frightening than the first time. This world was strange yet familiar to Murong Yi. The kimonoed women on the street, the man-eating ghosts in the ravines, the men and women holding sun swords... She remembered, wasn't this something from the TV series "Demon Slayer: Kimetsu no Yaiba" that she had just finished watching out of boredom some time ago! So, she just sneaked down the mountain to play at night, but was knocked away and reborn in a different world? From then on, there was a number one woman in this small world. Some people say she looks like an angel, some say she looks like a devil. Some ghosts say she is gentle, and some ghosts say she is cruel. "I am not the angel or devil you call me. I just follow my heart." "I am who I am, a different kind of fireworks!" "I will save everyone!"
