When the doomsday slave Zhu Yan, who was relegated to a blood sacrifice, was dying, his "Second Soul" unexpectedly resonated and activated the taboo card system engraved in his bloodline - [Hearthstone: Dark Moon Mystery]. He discovered that he could extract special "Source Stone" energy from the bottom of the city called "Arknights" behind the "Mission: Impossible"-style conspiracy, and convert it into card power. His awakening not only attracted the attention of the ancient guardian "Shadow Crow" who was hidden in the card in the form of a "Three-Legged Golden Crow", but also made him involved in a grand battle across the fantasy world and the "Origin Stone" technological conspiracy. In the story, Zhu Yan uses the deck rules of "Hearthstone" to defeat the conspirators who infiltrate high-level officials one by one using "Mission: Impossible" methods. Every victory makes the power of the Golden Crow in his bloodline stronger. Under the guidance of Shadow Crow, he explored the origin of 'Tomorrow's Ark' and discovered that it itself was a huge man-made 'Golden Crow'. What he wants to do is not only revenge and counterattack, but also to prevent this huge creation that combines technology and fantasy from completely losing control and swallowing the entire world.
