Transmigrated as a Sacrifice, I Talked the Demon Lord into Calling Me Master

Overworked office drone Lin Xi dropped dead and transmigrated as a cannon-fodder saintess meant to be sacrificed to an ancient Sword Demon. On the verge of having her soul wiped out, she activated the [Strongest Master of Bullshitting System] and immediately sold the newly awakened world-ending Sword Demon a corporate-style PowerPoint full of empty promises: “I’m your long-lost master! Come out into the world with me. I’ll make sure you eat and drink well and show you all the splendors of the mortal realm!” The naive Sword Demon, Ye Xiao, believed her and accepted her as his master on the spot. But Lin Xi soon realized something was off about her disciple. A passerby looks at her for too long? Her disciple says, “Master, this person has disrespected you. He must die.” She wants to skip the bill?
