Infinite Escape with My Mortal Enemy

Song Luan had only dozed off in class. When he opened his eyes, he found himself in a dim, unfamiliar room, with a classmate beside him who was usually his rival. On the table lay a slip of paper with a white background and eerie patterns. Its ornate lettering spelled out, with a hint of malicious glee: Hint 1: Find the key clues to leave. Hint 2: There is a ghost in this building. Hint 3: Both hints above are true. Use your own judgment to decide whether the other notes are true. Song Luan slowly shifted his gaze to Fang Qiao, who smiled faintly. "Minister, I'm not one to hold a grudge. Don't be scared." Song Luan: "..." Killing your teammate is against the law. Please calm down! I've wanted to write this kind of story for a long time. I'll start once I have enough favorites.
