An ultra-sweet story with no angst from beginning to end. A tsundere disciple x a tsundere master.
After Lu Lin, the chief disciple of Yi Jiu, the valley master of the cultivation world's greatest sect, defects from his sect and joins the Demon Realm, Yi Jiu personally goes to the Demon Realm to rescue him.
To humiliate Yi Jiu, Lu Lin makes him serve as his maid and attend to his daily needs.
The people of the Demon Realm hear about it and say, "So the greatest cultivator in the cultivation world is no big deal after all. Now that he's in our Demon Realm, he's fit only to be a maid."
Ten days later... "What kind of maid sleeps until noon? What kind of maid gets her master to carry meals to her bedside and feed her one bite at a time?" "Please, Immortal Lord, hurry up and leave. To keep you from drinking, there's not a drop of wine within ten li of the general's estate. I haven't had a drink in seven days." "So which one of them is really serving the other, him or the general?"
