On his 18th birthday, Sultan spent money to draw cards. As a result, he was possessed by a non-Emirate and all 648 was lost. She was so angry that she made a wish "please ask the system to give me a good card", but that night she was pestered by something claiming to be the "Doomsday Card Drawing System".
At first she thought it was an illusion, until a wave of mutant beasts broke out, the sky turned red as blood, and the world began to collapse.
The system told her: "Draw cards to survive."
Thus, Sudan began her doomsday card drawing career:
Blue Card·Human mecha repairman (enthusiastic and loyal dog, but always shy in strange places)
Zika Lord of the Ocean (Gloomy and poisonous tongue, once stabbed her in the back but tried his best to atone for his sin)
Zika Ghost King (a gentle man, but his true identity is a world-destroying powerful ghost)
Jinka Tyrant Emperor (arrogant and autocratic, but only recognizes her abilities)
The problem is - each of these cards is more difficult to get than the last.
She originally wanted to survive until the end, but...
The passionate mecha repairman taught her how to modify weapons every day, and his breath always fell behind her ears while he was teaching step by step.
The gloomy and poisonous Lord of the Ocean despised her, but when she was injured, he controlled the water flow to heal her.
The ghost king with a gloomy appearance was gentle and considerate, until she found him kissing her hair on a full moon night and whispering: "Madam, we have paid homage to each other."
The arrogant and autocratic emperor forced her to sit on the throne: "Either be my queen, or watch your safe house be demolished."
What's worse is that she gradually discovers that the truth of the card drawing system is far more terrifying than the doomsday.
Sudan: Thank you for the invitation. I am at the end of the world and I have just drawn the card. Now four men have said they want to talk to me about the future. Which one should I run first?
Purpose: Between disaster and redemption, find Sudan's own survival rules
