After Xianyu and the Demonic Dragon Got Married by Mistake

[The first 8 chapters are being rewritten, progress 3/8] Yun Shu has been practicing hard for many years and is about to enjoy retirement life, but unexpectedly, he loses all his cultivation, ends up living on a deserted island, and falls into the hands of a sealed demon. In order to survive, she signed a master-servant contract and became the devil's servant. Yun Shu, who had been a laborer in his previous life, was well versed in the art of fishing with pay, and worked hard to reduce his presence in the devil's cave and wait for an opportunity to escape. But for some reason, the aloof Demon Lord could always lock her in his eyes and focus on her! Yun Shu, who was very busy: Wait! When she escapes, she must report it to the Immortal Alliance and destroy the devil's cave! Little did she know that the master-servant contract was mistaken for a marriage contract. Not only did she get half of the Demon Lord's cultivation and lifespan in vain, but he was also responsible for all the injuries she suffered. The Demon King who lost more than a handful of rice:... During the days when he was "tortured" by the Demon Lord, Yun Shu picked up a proud little dragon. She went out under the guise of doing things for the Demon Lord, but in fact she went everywhere eating, watching movies and walking around, leading to a retirement life ahead of schedule. Seeing that Yun Shu was prospering and attracting the attention of the proud disciples of the immortal sect, the demon king who was originally bent on destroying the world and taking revenge tore open the seal: What should I do if I accidentally mistaken the master-servant contract for a marriage contract? I had no choice but to marry my wife with a smile (∩_∩) All the immortal monks had tears in their eyes: Thank you Taoist Yun for surrendering the evil dragon! I picked up a dragon for nothing and saved Yun Shu O. O from the world of immortality: Aren't I just a melon-eater? - [Realm: Qi refining, foundation building, golden elixir, Yuanying, spiritual transformation, out-of-body experience, integration, Mahayana, transcending tribulations] - Purpose: Live well no matter what the situation is
