After Passing Through the Book, I Bound the Dog-Licking System

"This is the third day that I have entered my own novel, and I am still a passerby with only one line and one plot..." Luo Yu squatted under the Demon King's castle, wanting to cry without tears. It is also bound to the 'dog-licking' system, and has inexhaustible 'dog-licking gold' for the bosses. As long as you lick it well, lick it properly, and make the mission target happy, you can choose any rare treasure that will shock the three worlds. "System, do you think the boss will be short of money?" Luo Yu asked speechlessly. "..." The system instantly felt that there seemed to be a bug in the task it had set. Luo Yuli's first target was the Demon Lord Long Yuan who killed him. When they met for the first time, Luo Yu shouted directly: "I like you." Long Yuan was speechless: "Kill." The second time they met, Luo Yu still shouted: "I like you." Long Yuan frowned and his face turned red with embarrassment. The third time they met, Luo Yu shouted again: "I like you." Long Yuan's heart moved, stop shouting, I will give you my life. Just when she was about to live a shameless life with the Demon Lord, the heroine Ling Shuang appeared. As soon as she appeared, she set her sights on Long Yuan. Only in the end did she discover that the heroine was also a time traveler with a script in hand.
