Introduction:

Rumor has it that within the city of Milin, there exists an ancient castle. This castle is extremely peculiar—though some people are aware of its existence, no one can ever truly see it in their daily lives, except on the second day of July every ten years. It is said that the castle is filled with mirrors, and upon entering, one will immediately see a massive clock. Inside, there are butlers and servants, yet everything within appears to be meticulously arranged—so much so that everything exists in eerie, identical pairs. However, there is one exception. The master of the castle has never been seen. And every ten years, the castle's master sends out mysterious banquet invitations. Those who receive the invitations are without exception elites from various industries, or individuals at the pinnacle of their fields. Regardless of who they are, they must attend the banquet—failure to do so results in punishment. Mysterious disappearances or death? No one knows. But when the chosen participants step into the castle, they gradually begin to uncover its terrifying nature. It seems to be more than just a mere game. Beneath the surface, hidden rules lurk in the shadows. One wrong step, and they will fall into the abyss, where only death awaits. **Rules:** 1. Do not wander freely within the castle. 2. Be cautious with your words and actions. 3. Those who know do not speak; those who speak do not know. 4. Go with the flow; do not defy the natural order. What you see is not necessarily real, and illusions are not necessarily false. All that appears before your eyes may not be the truth, and all that lingers in your mind may not be mere deception.
