No harem, no do-gooder protagonist, and decisive when it comes to killing.
He doesn't dote on his sister or save his mother. He's a lone wolf.
Genetic mutations begin, and humanity starts reverting to its ancestors. Mythical beasts from the Classic of Mountains and Seas emerge.
When humanity loses the intelligence it once prided itself on, how can physical strength alone help anyone survive the apocalypse?
The protagonist, Wei Jiyuan, unexpectedly obtains a card System.
N rank (normal), R rank (rare), SR rank (super rare), SSR rank (special super rare), UR rank (extremely rare).
When Wei Jiyuan gets his first card, he knows that even in the apocalypse, he can still live life to the fullest.
He roams among the mythical beasts of the Classic of Mountains and Seas and the humans reverting to their ancestors.
My cards are super rare!
It's a bit early to lay this foreshadowing in the early stage. After all, there are only a few cards, but it's okay. I personally don't like that my secret was known so early in the last chapter. Is it possible that people will be chasing him all over the world later?
