"If that's the case," Catherine stared at the map and said to herself: "I'm afraid these three moons really contain some hidden information, otherwise no one would be bored to depict the moon in strict angles and positions."

"Yes, after confirming this, I had further considerations." Panis explained: "If the moon was drawn according to the real situation, then the intention of the person who made the map would definitely not be placed on the moon alone, and would definitely be related to other things related to the moon. So I had two bold ideas. First, although the shape and characteristics of the pit were drawn casually, would there be some special information like the moon? For example, some data scales and other things, so I calculated the height of the pit on the map, the ratio between the opening radius and the bottom radius of the cave, and then calculated the inclination angle of the rock walls on both sides of the cave in the figure. Maybe these can be used to determine the specific pits in the figure."

"What about the second one?" Katherine was a little confused when she listened to Panis' explanation: "What is the second idea?"

"The second idea is to look out through the entrance of the cave." Panis pointed to the sky above his head and said: "That day, the position of the three moons will not change. In a pothole a hundred meters deep, it is not easy to see three moons in a complete hole. Therefore, just estimate the position of the three moons that night, and then test whether you can see the angle shown in the picture from each angle at the bottom of each hole, and then confirm it."

"Okay, I admit that I basically didn't understand a single word of your two ideas." Catherine hugged her head in distress and said, "The only thing I understand is that you want to estimate the position of the moon, and that thing can also be estimated? It's impossible, how can you estimate it."

"Uh, this, this is common sense." Panis suddenly discovered the other side of Catherine, and the corners of his mouth twitched slightly, and he explained with a smile: "Different months, different dates, different times, and the approximate position of the moon on the sky, those who have a little knowledge of astronomy will know, and I estimated it together with Vivian."

"Whose common sense is like this?" Catherine's cheeks flushed slightly, and she couldn't help but say loudly: "And when did astronomy become common sense? Different months, different dates, different times, who would remember this kind of academic theoretical thing? How could anyone remember things that have nothing to do with fighting and adventure?"

"Well, look, didn't Vivian and I go to remember them all, and no matter what, I remember them all, aren't it, hehe." Panis covered his mouth and smiled: "Or, a certain image of the bright and brave Knight, so lacking in knowledge..."

"Go to die." Catherine glared at her, but finally she could only breathe, drooping her shoulders weakly, and said reluctantly: "I understand, so when you reach the bottom of the pit, you look up at the sky just to estimate whether you can see the moon from this angle?"

"It's almost the same." Panis nodded, "but not seeing the moon, but looking for the same perspective as the scale and angle on the map."

"I don't understand." Catherine stared at Pannis with a dangerous look, and said in a very affirmative tone: "No matter what proportion, angle, perspective, and other messy things, they are all looking at the moon in the end."

"Yes, yes." Panis smiled bitterly and raised his hand to surrender: "We are just looking at the moon."

"So, you've observed these two times just now." Catherine's eyes floated to the side, not looking at Pannis' eyes, and changed the topic: "Have you confirmed that these two pits are not targets?"

"If my guess is correct," said Panis, "then you can basically eliminate these two pits."

"What if you're wrong?" Catherine asked, "What if you can't find a location that meets the criteria according to your ideas?"

"That means there is something wrong with my idea." Panis spread his hands: "Anyway, we have seven days to study it again if we make a mistake. What does it matter."

"It makes sense." Catherine said in a rigid voice that lacks emotional ups and downs: "If you hide the smirk on your face better, it will be even more convincing."

"Hahaha, that's just a misunderstanding." Panis took the lead in climbing up the rock wall as if he was running away, and said with a smile while crawling: "I'll go up and see the moon first, you can follow up quickly."

"Bastard, am I just a little less knowledgeable? What's ridiculous?" Catherine cursed angrily, and after scolding herself, she couldn't help laughing. She smiled and sighed, chasing Pannis and crawled out of the hole.

——————————

When Vivian woke up, the first thing she saw was Catherine's face.

It was dinner time. Catherine was about to walk into the tent to wake her up, and Vivian woke up automatically. Vivian, who had just woken up, opened her eyes blankly, her body motionless and speechless, and her eyes were turned around in confusion. After a long time, she realized what she was doing. Vivian, who had finally recovered from awakening, lay quietly for a while, then slowly sat up, stretched out her arms, curled her fingers, and nodded with satisfaction, grabbed Catherine's stretched out hand and stood up.

"It's getting dark, I'm ready to eat." Catherine's voice was very gentle: "How are you sleeping? Does your head still hurt?"

"I have recovered a little, and it won't hurt for the time being." Vivian said, "I just don't know how long it can last."

"Since you've been relieved, you can continue to sleep tonight." Catherine said: "In the past few days, you should not do too many activities except for necessary things. Take advantage of your spare time to replenish your overdrafted mental power."

"Well, thank you sister." Vivian was not polite and accepted Catherine's kindness simply: "How are you going to investigate today? Have you found the entrance?"

"Well, maybe I found it." Catherine said uncertainly: "You should ask Panis. He explained it for a while, and then Lina and I rushed to get the water."

"Hahaha, you're still the same." Vivian coughed with a smile and gasped, "This is the tragedy of insufficient knowledge, hahahaha."

"Give me a little bit." Catherine pressed Vivian's head and rubbed her blue hair: "You go and discuss it with him. We can't stand it anymore. He's already crazy."

As soon as he walked out of the tent, he could see the crystal energy lamps lit by the campfire and the white paper spread all over the floor. Pannis lay on the ground, crawling around the ground with the lights, constantly recording on different papers. When he found that Vivian had walked out, Pannis seemed to have seen the savior and said urgently: "Vivian, come, come, help me calculate. My calculation ability is still much worse, and I am almost tortured by these numbers."

"Give me a honest meal." Catherine roared, completely dispelling Vivian's eagerness to try: "No one is allowed to start writing before he finishes his meal."

"Yes, the leader." Panis was so scared that he jumped up on the spot and jumped directly to the campfire: "Eat now, never write."

"I deserve it." Lina, who went to inform Elad, just walked back. Seeing Panis' embarrassing look, she said with a snicker: "I should have asked my elder sister to scold you like this long ago."

Vivian also sat down, took the plate handed by Catherine, but glanced at the paper on the ground, glanced at the randomly, and said with a sudden realization: "It seems that there are two possible places?"

"Yes, this is the most troublesome thing." Panis held the plate, but was not thinking about eating at all, and mechanically stuffed food into his mouth. "I found two holes, which fit the requirements of our two conjectures. Whether it is calculated from the ratio of height and radius, or from the position and angle of the moon, they all meet the conditions of the conjectures."

"So." Vivian forgot to take it out in his mouth and said vaguely: "Either, our guess has gone in the wrong direction from the beginning, or there is a third condition hidden in the map and we didn't find it."

"Well, I prefer to hide the third condition." Panis said: "After all, the first two conditions have already matched. If it is just a coincidence, it would be too far-fetched. The person who draws the map is not brain-related, so there is no need to create such coincidence. Of course, if this is a misleading made by the Naren royal family to confuse others, that is another statement."

"Are you finished?" Catherine said dissatisfied: "It's already a headache for Vivian to fall into a frenzy. Pennis, why are you learning to go crazy with her?"

"Sister, you don't understand." Vivian replied happily: "The charm of this puzzle game lies in finding the correct clues from rare conditions, and then finally finding the answer through these clues. This kind of thing is simply too interesting, right, Pennis."

"Yeah, that's right." Panis was covered in cold sweat from Catherine's stare, almost buried his face in the plate, and said vaguely: "It's very interesting, yeah."

"I really don't understand." Catherine turned her angry eyes to Vivian again: "But I know that if you do this again, just talk and don't eat, you will not be allowed to participate in this treasure hunt. Don't challenge my determination. This is the last warning. There is no next time. Give me a good meal. Especially you, Vivian, if you do this again, you won't even bring you out next time."

"Sister, I was wrong." Vivian was very skillful and bowed his head to admit his mistake. He kicked Lina, who was gloating, and pouted and stopped talking, focusing on dealing with the food on the plate.

"The time is still good." Catherine sighed and explained, "Don't rush to rush these dozens of minutes. We will listen to the discussions between you two after dinner. Moreover, it is difficult to fully understand just this discussion. After tomorrow dawn, let's go down to conduct on-site inspections. Isn't it better than your guesses like this? So, don't be so anxious, everything must be done step by step."

"Well, okay, sister, listen to you." Vivian finally returned to normal from the fanatical puzzle solving state, nodded and said, "I'm determined, I'll go down to investigate tomorrow. However, this puzzle is really interesting. I didn't notice it at all. If Penis hadn't proposed the guess about the three moons, I would have been tricked. Haha, sister, from this point, I had a premonition that we would definitely gain a lot this time."
