FamishedGod

Sana Scarlett, the notorious criminal with the ability to Devour other people's abilities, and Ethan Everhart, an inconspicuous bartender who was also her childhood sweetheart, vanished from the face of Earth on a random day. 

Nobody knew where they had gone, and only they themselves knew that Ethan had received a call from somewhere far away. From another world, the Immortal World. 

And on their first day, they also gained the greatest Immortal Sect's legacy. 

They even had the abilities that they carried over from Earth!

....

Expect:

A very intriguing Cultivation System.
Nice world-building.
Meaningful characters.
Nice plot. Plot too.
And a very vast world.
No cliché!
Explicit lemons!

No harem.

Earth's Strongest Couple in the Immortal World

They killed some more animals that day. Some birds flew by, and another bear was in a cave. But the first halo manifestation was still a distant thing.

They still felt a slight sensation of being stronger, regardless, though. And Ethan's skinny form that had been sapped after using Massless Body became buff again.

Colorless Essence was indeed a top-tier body-building material. Literally.

So it was not that bad and since they would become Cultivators in some time anyway, they didn't immediately try to get in touch with the Human Matriarch.

There was no immediate need to socialize. They decided to accumulate as much strength as they could before they began socializing and trying to get out of the walls.
