We Agreed On Experiencing Life, So Why Did You Immortals Become Real?

Create different characters and experience wonderful lives. The story begins with transmigrating into the body of a mascot emperor in an alternate world. Through the Book of a Hundred Lives, one can experience different lifetimes and receive rewards by completing tasks. Restoring the royal family’s glory is our generation’s unshirkable duty!
Within the Book of a Hundred Lives:
I became the Holy Son of the Ten Thousand Dao Sect and debated the Dao with the Wonderful Lotus Saintess. As a result, her dao heart shattered and thousands of black threads grew from her mind.
I became a down-and-out scholar and saved a white snake. I helped her successfully overcome tribulation and transform into the last true dragon in the world, but she said she would never let me go for all eternity.
I became an elder of the Dragon Spring Sword Sect and took in a disciple. I cultivated her into the world’s first sword immortal, but she came to hate me to the bone.
Finally, one day, I reclaimed imperial power. Thinking I had reached the other shore while walking on thin ice, suddenly the sky above the imperial capital split open with ten-thousand-zhang dark clouds!
A massive white dragon head emerged from the cloud layer, staring at me intently.
Wasn’t this supposed to be about experiencing life? How did everything become real?
