What do I mean by saying this? Actually, I don't know, just talk about it casually.ps. Friends who pass by ask for collection and recommendation. Your support is my greatest motivation.)

"Where will it be the key?" Catherine said thoughtfully: "It must be related to the Institute when it is still carried with you at this time."

"Don't think about it, sister." Vivian reached out and patted Catherine on the back. She could only reach Catherine's back: "You will always understand the specific situation when you continue to go deeper."

"Yes, at least we don't have to worry about it." Lina walked through the living room and opened a door leading to the interior: "We don't have to worry about monster attacks at any time like Tomal, the previous rescue team, the monsters transformed by humans will not have that long lifespan, and the previous rescue team has almost been cleaned up, and the rest is not enough to reproduce a monster group. Wow, ahhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh

Hearing Lina's sudden scream, Katherine and Panis started to rush towards Lina at the same time, and Vivian also shouted anxiously: "Lina, what's wrong with you?"

"These, these, these..." Lina's voice sounded normal, but her words were confused: "These... mine... are all mine. You are not allowed to rob it, and no one of you is allowed to rob it from me."

"Okay, I think I know what it is." Catherine, who had already rushed to Lina's back, could not see the situation inside the door because she was blocked by Lina, but when she heard Lina's words, she obviously understood: "Don't worry, no one will snatch it from you."

"Great, long live the eldest sister." Lina cheered and rushed into the inner room and shouted, "I want to bring them all back."

"It's a book." Panis saw the bitter smile on Catherine's face and sighed: "I think it should be a book."

"It should be..." Catherine followed Lina into the room, and the words in her mouth suddenly stopped. After a moment, she continued unnaturally: "Many books, many, many books."

"Let's go in together." Vivian pushed Pannis and turned around and waved to Rachel: "Rachel, come in and take a look."

When everyone walked into the inner room, they were stunned for the first time. The inner room was big, larger than the living room outside. It was a rectangular room of 700 to 800 square meters. The four walls of the room were arranged on the entire wall of the other three walls, with the same specifications, from the ground to the height of the roof. The bookshelf were densely filled with various books, with tens of thousands of volumes. At this time, Lina was standing greedily in front of the bookshelf, constantly from the

I took out a book on the bookshelf, put it in my arms and hugged it tightly, and then put it in my backpack. Every time I hugged a book, I was still muttering: "Helen, it's been a long time since I'm back. Wow, Martha, you're still so sloppy. Hey, Linda, I miss me so much, come and hug it, ha, you're the same, still so cold. Katerina, wuwuwu, Katerina, I finally got home, I miss you so much, wuwuwuwu."

Seeing Lina who was completely out of control when she cried and laughed, Panis looked at Katherine in confusion. Katherine sighed with pity and shook her head: "Let her be alone for a while, don't wake her up, let's see if there are any valuable clues. Let's see, Lina is a novel, a professional book, well, this part is history, this part is geography, and various magic theory works here."

As he walked casually, Catherine walked to the desk placed in the middle of the study, and confirmed that the desk and seat were still strong before she sat down and opened several drawers of the desk.

"These should be accounts for a few years. Do you need to check them?" Catherine asked Penis for his opinion.

"Not needed for the time being." Panis shook his head: "It's not too late to see when you encounter problems and need to find clues."

"Okay." Catherine put a thick account book in a drawer into her backpack, and then picked up a stack of reports in another drawer: "I can't understand, Vivian, this should be your mage's thing, look."

Vivian took the report and flipped it over and threw it on the table: "It's useless, these are the progress reports of various research groups. I looked at it and it was all mature theories, which were completely meaningless."

"What about these?" Catherine handed over another stack: "I can't understand the words inside at all."

"Well, it's interesting." Vivian looked at it for a few minutes and then raised her head from the pages of paper: "It seems that the director of this institute also belongs to the Naren royal family. This is written in magic secret text, and it is a letter he reported to King Naren's research progress. In it, he mentioned a secret storeroom that only the Naren royal family knew. Oh, damn it, he changed the secret text, I can't understand the key points. It's really a god, I have to take this back, I have to check it before I can translate it."

"Storage?" Catherine's eyes immediately lit up: "Are you sure?"

"It's just not sure." Vivian looked helpless with a look of "I know": "Don't be excited, if you are sure, I will tell you as soon as possible."

"I'm sure." Catherine smiled satisfied and put away all kinds of papers on the desk in turn: "It's a pity. There seems to be no other valuable clues here. I don't understand why such troublesome protective measures are used."

"On the one hand, it's for safety, after all, the director is a member of the royal family." Panis's eyes kept staring at a bookcase: "On the other hand, haven't you noticed that there is a part of it missing?"

"Bedroom?" Catherine followed Pannis's gaze and looked at the bookcase: "The secret door is behind this bookcase?"

"Sister, you will understand when you walk over and touch the cabinet." Vivian was still buried in the report letter he had just bought, and said without raising his head.

Catherine walked to the bookcase with a little confusion, reached out and touched it, but found that the extended hand penetrated into the bookcase without any obstacle: "Is this an illusion?"

"Well, it's a very simple illusion." Panis replied: "There is no hidden meaning at all. It is estimated that the illusion is just for the sake of beauty. Any explorer, thief, ranger or spell casting profession can easily discover it."

"That is to say, I can't find it here." Catherine muttered in a bad mood, and reached out to try the range covered on both sides of the illusion: "After seven or eight hundred books are missing, Lina is going to be disappointed, ha."

Push open the door covered by illusion. Inside the door is a bedroom of more than 30 square meters. The metal walls of the bedroom are carved with many fine patterns. The thick cashmere carpet on the ground has rotted with time. Some potted ground plants on the ground have withered, and even some famous paintings on the wall have become moldy and discolored.

"What's going on? Why do things here rot? Isn't there a magic circle for water vapor?" Catherine frowned and said, "Even if you find any valuable clues, you can't read it."

Panis pointed to the two extremely small umbrella-shaped fountains in the corner of the wall that have been operating silently for hundreds of years: "For the comfort of living, it seems to be the privilege of the director. However, the container that really preserves things should be embedded with magic circles to drive away water vapor to prevent moisture from being affected."

"Okay, anyway, open it and see." Catherine walked to the only cabinet beside the bed and observed the safe made of extremely heavy metal: "That's a hell, such a thick shell."

"I'll do it." Panis looked at the inline lock that looked very complicated on the cabinet door. He took out a few gadgets and gently flicked it in the lock hole a few times. The cabinet door opened easily. The space in the cabinet was actually not large, and it was a pity that there were no other items except a few purses. Catherine took out the purse and threw it on the bed, and carefully searched the empty cabinet.

"It's true that there is a secret lattice." Catherine happily took out a thick book bound into a volume of scattered paper and a single folded piece of paper from the secret lattice of the cabinet. She first opened the separate paper and looked at it and handed it to Pannis: "This should be the complete map of the underground institute." She opened the volume of paper and looked through a few pages and handed it to Vivian: "It's also a research progress, please see if it's useful."

Vivian glanced a few times in a hurry, her eyes lit up, and then closed the book and said, "There is nothing very novel in technology, but there are some good assumptions that can be learned from, which is quite useful."

"There should be nothing else." Catherine always felt that the harvest was not consistent with the previous level of defense at the gate, but the things in the secret wall were indeed very important and secret to the institute. It is reasonable to use that level of defense, so she had to say unhappily: "It seems that this is the one, it's really a pity."

Panis put his hands on his chest and suddenly spoke: "Everyone may become an explorer, as long as he can observe carefully and imagine boldly. In fact, Katherine, you might as well exercise your observation ability and perception. Maybe you can also become a good explorer. In this way, you don't have to unwilling unreliable teammates to join the adventure team, and on the other hand, you are worried that there is no trouble for the explorer."

Catherine tilted her head, frowned and asked uncertainly: "Pennis, what do you mean?"

"Nothing, just talk about it." Panis smiled very rarely, patted the metal wall beside him and said: "If people want to hide things, hiding in the most hidden place is actually the lowest level, and hiding in conspicuous places is not the most clever way. The real wise way is when you think there must be something hidden here, there is something hidden here. But when you feel that you have seen through the other person's thoughts and found the hidden object, the things are actually not here. There is a secret wall hidden in the most common method, and the most valuable one should be here."

Catherine didn't even bother to think about the implicit meaning of Panis's words, and went to the place where Panis had just slapped and checked it carefully. Panis sighed and said, "You can try to find it. I'll go out and see Lina and Rachel, they haven't come in."

"Okay, okay, go." Catherine nodded and said, "I'll look for it."
