[System + unrelated adoptive younger sister as the sole heroine + Naruto + lighthearted + not brainless]
In 2080, Earth underwent a sudden transformation, and all kinds of ferocious beasts appeared. Humanity was powerless to fight back. A group known as the Will-Bearers opened passages to the moon across the globe, and the remaining humans fled there.
The protagonist, Jiang Xian, was an idle sort. By chance, he was born into another world, but while still a baby, he was sent to the moon. His parents died in the transit passage. Years later, he met Jiang Mang. Just then, the System announced: [World Will-Bearer detected. Take in a Will-Bearer to obtain the Sharingan: Uchiha Itachi.]
For the perks, Jiang Xian signed up for the school’s Couples’ Club with Jiang Mang. He had no idea it was a hidden one-way ticket back to Earth. After all, what kind of normal school would have a club like that?
Moon, Huaxia, Guanghan Palace: “We will once again tour our great land!”
“Wait, you’re seriously asking me to reclaim lost territory?”
“By the way, System, we can use our Flying Thunder God between the moon and Earth, right? I’ll put a mark on my sister and another one at home. Heh.”
I heard it's easier to get angry if you come early?
We? I'm the only one watching!!!??
A very good novel, I feel like there is very little nonsense and a lot of work.
