When I walked to the seventh floor, it seemed that there was no difference from the six floors below. It was the same wooden floor and a circle of bookshelf was stored, but there were no books on the bookshelf, making this floor look more like a warehouse where bookshelf were placed.

Lin Xuan was slightly stunned when he looked at the bookshelf. Naturally, he would not simply think that the bookshelf here were just randomly placed here. Judging from the previous aspects of this treasure house, almost every part of the space has been carefully processed, and there is almost no useless place to place it casually.

Even if there is no use in the inner warehouse, some treasures will be stored in the wasteland waiting for those who are destined to discover. Then the place where this core treasure house is located must be very exquisite.

However, there is indeed no trace of the treasure house here. After coming up from the stairs, I saw an empty hall with several bookshelves around it... There was not even a carpet on the ground, which was very contrary to the exquisite feeling in other places before. If I hadn't known it was still in the treasure house space, it would have been very similar to the warehouse.

"This core treasure house in Xiaoyi's mouth... I have studied it before, and it seems that it is not easy to open." The Dragon King scratched his head. He had arrived before, but he really couldn't find a way to enter the core treasure house.

It is unlikely that Xiaoyi deceived them. If Xiaoyi was hostile to them, she would not allow them to enter the treasure house space at all, let alone that they have taken away some treasures now, and they have taken away some of the herbs in the outer warehouse or the inner warehouse.

Lin Xuan and the Dragon King walked around the top floor. The Dragon King had been here before, so he was very familiar with this place. However, there were so many things on the left and right, and there was nothing else to be familiar with. After all, you can see it at a glance.

"The bookshelf here cannot be moved. It should be placed into a formation. As long as this formation is activated, we should be able to find a way to enter the core treasure house." The Dragon King looked eager to try, looking like a detective investigating a case. It seemed that he wanted to study how this formation was arranged by himself.

Lin Xuan smashed his mouth. Originally, Lin Xuan didn't want to disturb the Dragon King's exploration, but it seemed that the Dragon King wanted to study the formation here for at least a few years...or maybe it wouldn't be able to study it for several years.

Daoyuan just told Lin Xuan that the formation here was arranged at least eleven in the late stage of the Heavenly Realm. As for whether it was arranged by the Supreme Realm, Daoyuan had to try it personally to determine this. After all, although Daoyuan had a high vision, without the support of strength, he was just a pavilion in the air.

Thinking back then, when Lin Xuan was relatively low, even cultivators at the Heavenly Realm level could discover Daoyuan. Later, Lin Xuan's cultivation level improved, and it would be better to have the protection of the Heavenly Dao. However, Daoyuan now does not have the strength to crack things set at the Supreme Level. Perhaps Lin Xuan had at least the strength in the middle and even late stages of the Heavenly Realm to move Supreme Things.

This seemingly randomly arranged bookshelves, which seemingly very simple, contains a very mysterious formation. Daoyuan saw that this formation must be arranged at least in the later stage of the Heavenly Realm, so Daoyuan advised Lin Xuan to quickly talk to the Dragon King that he would not go down to see other Heavenly Realm-level classics when he broke the formation.

"Hiss, this formation is really exquisite. Lin Xuan, why don't you call the fat man over? This formation is even better than the previous Fuxi formation. It's really wonderful." The Dragon King ran to the bookshelf here and to the bookshelf on the other side, and made some amazing sounds from his mouth from time to time.

Although the Dragon King had been here before and had a rough look at the furnishings here, he had not carefully studied the formation before. Before, he looked at the following martial arts and martial arts. Later, he sensed that Lin Xuan came back and went to pick up Lin Xuan.

This is the first time that the Dragon King has studied such a complete and exquisite formation. The Bagua formation was a bit broken before, and it was a rubbing version. Although it is still extremely exquisite, it is still much worse than this intact formation. So now the Dragon King is fascinated by seeing it.

"Well, Dragon King, we are still an advanced core treasure house. We can study this formation in a while." Lin Xuan spread his hands while spreading his hands and was a little speechless about the Dragon King who was trapped in the research.

"Yes, am I studying this? We'll go in after I've studied it." The Dragon King said naturally.

"..." Lin Xuan said with a wry smile: "Well, Dragon King, we don't need to be so complicated. It's very simple for us to enter the core treasure house."

"Can you break this formation?" The Dragon King looked at Lin Xuan's eyes and said with a smile: "I haven't heard that you have also studied the formation. Tell me how to break this formation?"

"We don't need to break the formation... Just call Xiaoyi out." Lin Xuan was a little helpless when he spread his hands.

"Uh(⊙o⊙)..." The Dragon King was stunned for a moment, patted his head hard and said, "Oh, look at my head, I'm taking this as a parallel space."

"It's okay, let's call Xiaoyi out." Lin Xuan smiled and shook his head. This place is indeed very similar to the parallel space, but compared to other parallel spaces, there are only treasures here without danger.

It is normal for the Dragon King to bring over the habit of exploring parallel spaces. After all, if they encountered anything sealed in parallel spaces before, they basically broke the formation before entering. This time, when they saw such a huge formation, they subconsciously chose to directly crack the formation.

"Xiaoyi, stop watching the show, come out quickly!" Lin Xuan raised his head and shouted. Lin Xuan felt that Xiaoyi must be watching them here, and she was really naughty even though she hadn't come down.

"Here you come..." A blue light flashed in the air, and Xiaoyi's figure appeared in front of Lin Xuan and the Dragon King... Lin Xuan strongly believed that Xiaoyi must have been following him, otherwise why would she appear every time she called her, without hesitation at all.

"Please trouble you." The Dragon King looked at Xiaoyi and nodded gently. The Dragon King remembered that Xiaoyi didn't seem to like her that others called her very old, and it seemed that she was also a childish person, so the Dragon King did not call Xiaoyi a senior like he did at the beginning.

"No trouble, no trouble..." Xiaoyi said with a smile, but her eyes were staring at Lin Xuan. Lin Xuan was a little helpless. Now he was targeted by someone.

Xiaoyi raised her hands and began to erect on the highest floor of the library. The bookshelf placed next to her also began to emit some mysterious light, and blue lines spread from the bookshelf, at the center of the hall on the top floor.

After a while, the entire top layer seemed to be trapped in a ray of light. Lin Xuan felt a light that seemed to be inspecting sweeping over him. Then, a soft light emanated from his body, and this light was exactly the same as the one that shone on them when they entered the inner warehouse to check.
