After Being Controlled by the System to Cut Off the Dragon's Horns, I Killed the Way of Heaven

I am the only descendant of the dragon clan, but I was forcibly bound by a monster called System. My spiritual veins were also controlled by it, and I was asked by it to get close to a mortal called the male protagonist. So I stole intelligence for him, assassinated enemy generals, made suggestions, and helped him defeat the enemy country. It can be said that all his achievements were earned by me. But after the celebration banquet, I was surrounded by soldiers and clamped down, and I knelt down in embarrassment. Li Chengyao looked apologetic: [Yao'er, the princess is seriously injured and needs to borrow your dragon's horn. ] I gritted my teeth and stared at him, saying word by word: [The dragon horn is the true source of my life. Losing it is equivalent to killing half of my life. ] Li Chengyao frowned, with a look of condemnation: [It won't hurt your life, so don't be so selfish. ]
