Xia Sen obtains the [Health System]. This isn't the Health System from a gaming arena; it's a System that rewards him for helping people overcome sub-health conditions.
And so begins a series of major campaigns to save people's health.
His roommate stays up all night playing games?
Not getting enough sleep means the body can't repair itself. That's really unhealthy.
He sticks on a [Early to Bed, Early to Rise] magic card. When bedtime comes, his roommate drops right off, then wakes up forcibly once he's had enough sleep.
A rich kid has a serious addiction and changes the women around him every day?
That's a lot of energy. Er, no, it's really unhealthy.
He sticks on a [Eliminate Desire] magic card. From then on, the guy wants nothing and sees women as if they were poisonous snakes and scorpions.
The boss of a publicly listed company has to attend business dinners every day, constantly eating and drinking.
Overeating is bad enough, and alcohol damages the liver. That's seriously unhealthy.
He sticks on a [Food and Drink Pass Right Through] magic card. No matter what the guy eats or drinks, it'll all be see you tomorrow.
With the [Health System] and countless magic cards in hand, Xia Sen shouts:
"All of humanity, listen up! Every last one of you, stay healthy!"
Welcome to the daily life of a card master saving humanity from sub-health.
The blurb packs a punch, and the story hits even harder.
