"There are many ways to beat you. The only difference is how I choose to beat you."
Bai Zhi's gaze swept over the enormous display cabinet behind Doll, and a faint chill entered his eyes.
"You seem to look down on humans? Is it really so fun to torment them like this?"
"Yes~ It's fun, extremely fun. Your future was already destined long ago. What's wrong with keeping a few of you as collectibles? Lowly creatures like humans are far too fragile. You only have value as collectibles."
Doll's voice was full of leisurely amusement.
"Alright, I'm done with my riddle. Now it's your turn. No matter what question you ask, as long as you know the answer in your heart, I will surely know it too. So how are you going to ask the first question in your little game?"
"I'll ask a riddle, of course. But you seem to have withheld a rule, haven't you? Why don't you tell me that hidden rule first? There's no rush for me to ask my question."
Bai Zhi lazily replied as he raised a hand and lightly pressed his forehead.
"For example, how much time do you allow for answering? A guest's answering time can be unlimited, as long as they don't leave this shop. But you should have some kind of time limit, shouldn't you?"
"Hmph... Ten minutes. But I won't need anywhere near that long. Are you asking your question or not?"
Doll let out a cold snort.
"Very well. Listen carefully, then. My first riddle."
Bai Zhi snapped his fingers and spoke calmly.
"Arrange the 2,563 natural numbers from 1 to 2,563 in a circle. Keep 1 the first time, cross out 2, then keep 3, cross out 4... Continue like that, keeping one and removing one. What
