We agreed to just experience life, so why did you actually become a fairy?

To restore the glory of the imperial family is our solemn duty! Within the Book of a Hundred Lifetimes I became the Holy Son of the Myriad Dao Sect. I debated the Dao with the Holy Maiden of the Lotus, only for her Dao heart to shatter, leaving her consumed by endless obsession. I became a destitute scholar and saved a white snake. I helped her successfully transcend her tribulations to become the last true dragon in the world, yet she vowed never to let me go, through all my incarnations. I became an elder of the Dragon Spring Sword Sect and took a disciple, nurturing her into the world's greatest sword immortal, only for her to harbor a bone-deep hatred for me. Finally, one day, I reclaimed absolute power. Walking on thin ice, I thought I had finally reached the other shore. Suddenly, above the imperial capital, the vast dark clouds split apart! A massive white dragon head emerged from the clouds, staring fixedly at me. Wasn't I just supposed to be experiencing different lives? Why has it all become real?
