After Binding the Death Robbery System, I Snatched the Royal Power and Wealth

After traveling through time and becoming the fiancée of a wealthy and powerful king, I was bound to the "Death Tribulation System". As long as I let him experience the fate of ten thousand swords piercing his heart, I can reach the pinnacle of immortality. I carefully arranged for him to meet the little demon and weaved a love disaster for him. But when Ten Thousand Swords were aimed at his chest, he used the swordsmanship I taught him to smash the flying swords, and chuckled in my ear: "Master, you missed one trick - how to fall in love with you."
