Fell into Demonic Cultivation Following My Senior Brother

As the Demon Lord's only junior sister from the Immortal Dao, Xuan Ying once thought that she and her senior brother had only each other. Then one day, news broke that her senior brother, the Demon Lord of the age, was going to marry the number one beauty of the Immortal Dao.

Xuan Ying was furious. "I won't allow it!"

Determined to keep her senior brother all to herself, Xuan Ying forcibly cornered him against the wall and declared that she could do it too. Instead, the whole thing backfired.

Her senior brother's face turned red, then pale, then red again. He didn't dare show his face for half a month.

Unable to deal with her senior brother, Xuan Ying decided to deal with the Immortal Dao beauty instead. But halfway there, the Demon General guarding their home sent an urgent plea for help.

"We're doomed! Help! The Demon Lord has lost his memories of falling into demonic cultivation and turned back into the Sword Venerable he used to be! He's going to slaughter the Demon City and uphold justice on Heaven's behalf!"

Xuan Ying: "???"

Xuan Ying, the mistress of the Demon City, had always had such powerful backing that she could go toe-to-toe with the leader of the Immortal Dao. For the first time in her life, someone had blown up her home.

This had to be karma for pinning her senior brother against the wall.

Seven hundred years ago, chaos engulfed the Immortal Dao. Her entire sect was slaughtered, and the virtuous, illustrious first disciple of Yuntian took his junior sister in his arms and slaughtered his way into demonic cultivation, rebuilding himself from shattered bones.

After gradually taking control of the entire Demon Realm, the Demon Lord stood guard beside the Demon City with his sword in hand.

But one day, he returned to the city with his junior sister's favorite pastries, only for her to confront him furiously and say something so outrageous that he was left speechless.

After reflecting for a long while that only the best things were worthy of his one and only junior sister, the Demon Lord decided to turn himself back into the Yuntian sword cultivator he once was.
