National Destiny Marriage: I Simulate Infinitely to Claim Every Goddess

The National Destiny Marriage Game descends upon the world, forcing humanity into a high-stakes trial where participants choose from four doors at random. A single misstep can bring catastrophe to an entire nation. However, Qin Lang is different. Blessed with the Word Dao System, he begins with the ability to simulate outcomes through unique entries. In his tenth simulation, he marries the stunning Immortal Song Yu, granting his nation, Great Xia, an additional ten years of lifespan and a significant boost in physical constitution. The country erupts in jubilation; even the terminally ill are revitalized, recovering enough strength to run ten kilometers. As Qin Lang progresses, the rewards become increasingly lavish. Successfully cultivating with the immortal grants the entire nation thirty minutes of dual-cultivation time. While other countries tremble in fear before their choices, Qin Lang confidently embraces the Immortal on one side and the Thunder Goddess on the other. Soon, the Elf Queen and the Goddess of Fate join his harem. His system not only allows for simulation but also enables the dismantling and synthesis of traits. In his thousandth simulation, he deconstructs and combines useless entries to defy fate, acquiring a god-tier skill based on causal paradoxes. With Great Xia rising to dominance and Earth becoming invincible, Qin Lang pushes further. In his ten-thousandth simulation, he opens the door to the core control room of the marriage system, uncovering its hidden secrets. From goddesses across myriad worlds to national destiny resources, the truths of the heavens, and divine civilizations, Qin Lang declares that he will claim them all.
