In the MCU/Marvel with the Omnitrix/Ultimatrix - Chapter 37: Recalibration

After seeking pleasure in the nightclub and a night of romance, he discovered there’s a seed in his stomach;

I was reincarnated into the world of a novel I’d only read the free chapters.

Thankfully, the blood flowing in the body of the person I’d possessed was blue.

“The prominence of our family comes from the blessing bestowed upon us by the royal family throughout the generations.”

Maybe this is the price to pay for that. But I got a father who seems overly loyal to the Emperor. And because of that, I was forced to become a Civil Servant.

While everyone else enjoys romance, I’m just spending my days as a Civil Servant.

Immediately after Gu Changge realized he had transgressed into a fantasy world, the world’s protagonist, and fortune’s chosen, vowed to take revenge on him. Envied by all, he not only has the female lead head over heels for him but he’s also treated as a distinguished guest wherever he goes. Fortunately, Gu Changge’s prestige and power are superior to everyone else’s, so shouldn’t it be easy to trample on a mere fortune’s chosen?

The mortal body, metamorphosis, longevity, immortality, and eternal life. These five realms, step by step, reveal themselves in front of you. As a normal person, how can one try step by step to reach and open the door to eternal life?

Between the heaven and the earth lies the mortal body, the mysteries of metamorphosis, freedom of longevity, the power of immortality, and the hope of eternal life. A story filled with endless new magic, a new world of immortal styles, people, demons, gods, fairies, magic, kings and emperors. A world of love and hatred, revenge, and mystical battle, all in “Eternal Life.”
