Reincarnated as the Baron's son: My Infinite Card Upgrade System - Chapter 20: Negative relationship.

When the new snow begins, the full moon will be in the sky

The shadows are tiled below

Shining silver on it

And you walked towards me with a smile

Between the moon and snow

You are the third stunning color

——Yu Guangzhong “Stunning Color”

- Description from Novelupdates

Song Fengwan was dumped by her fiancé, who had been dating her for a year, and an illegitimate daughter appeared out of nowhere to ruin her family.

They had been married for less than a week when Lin Banxia discovered that without his embrace, she couldn’t sleep; without his love, she felt anxious; without his companionship, her emotions spiraled out of control.But then one day, she had stomach troubles!The hospital handed over a test result: Congratulations, Mrs. Huo, you’re pregnant.He said, “Give birth to my child, and we won’t just have three years together—we’ll have a lifetime!”She squinted her eyes and replied, “Mr. Huo, you’ve miscalculated. Clearly, after giving birth, you’re letting me go in three years.”“The child can’t go without a mother, and I can’t go without you. Understand?” That was Young Master Huo’s confession.

One day every human on the world suddenly receives a mail claiming to enact the World Salvation Project. Half in doubt Kurosaki Shion, a diligent university student and loner, follows the mail’s instructions, becoming one of a million Demon Kings governing his very own Domain in the new world.

*** This is a post-apocalyptic story containing many fantasy elements. It is a somewhat dark tale following Shion as he grows while aiming for the unification of the all too sudden new world. It has many game-elements bolstered by strategical thinking while at the same time providing funny moments and romantic encounters.
