Senior Sister Xianyu, but Forced to Be Invincible

After being transformed into the senior sister of the number one sect in the world of cultivation, Su Wan just wanted to show off in a low profile. Every day, I slept until three o'clock in the morning, swept the dust in the Sutra Pavilion, watered the fairy grass in the back mountain, and watched my fellow disciples live and die. Unexpectedly, the demonic invasion, the collapse of the secret realm, the destruction of the ancient beasts... Whenever the sect is in disaster, there is always the nameless sword light that just happens to resolve it. The leader cried with joy: "It must be a hidden ancestor of our sect who is secretly protecting me!" The leader of the Immortal Alliance was extremely excited: "This senior must be the one I love for my righteous destiny!" Both good and evil have been searching for him for decades without success, and the number one unsolved case in the world of cultivation, "The Mystery of the Mysterious Guardian," has not been solved for a long time. Until one day, the emperor of the immortal world projected himself into the lower world, oppressing all living beings and trying to seize the sect's treasure. When the whole sect was in despair, Su Wan rubbed her sleepy eyes and took out a rusty iron sword from the corner of the Sutra Pavilion: "It's so noisy, why don't we let people take a nap?" With a wave of his hand, the sword light pierced the sky.
