As soon as Murong Yunyi's words fell, seeing what the four of them were going to say, he immediately said in a cold voice: "Four junior sisters, you know what you are thinking in your hearts, there is no need to alarm the valley master in this matter! Moreover, as your senior brother, I will remind you for the last time, some dreams are still not good, don't always put your mind on some impossible things, otherwise you ......" Murong Yunyi didn't finish his words, just glanced at the four of them coldly, turned around and left the main hall.

On the other side, Yun Xi and Chen Xi took Qiao Xiaoyue and the others to dodge non-stop, and finally persevered until dawn. After dawn, the ghosts were gone. After that, the few people found a place to rest and recuperate for a while, and then they headed in the direction of the City Lord's Mansion together, and they also went to check the study. Although, after the events of last night, they were fully aware of the dangers of this trip, theoretically it would be wisest to abandon the mission now. However, having come to this point, none of them wanted to give up, so after discussion, the group decided to take the risk!

Half an hour later, Yun Xi and Chen Xi stood in front of the study of the City Lord's Mansion and began to try to lift the ban on the periphery of the study, while Qiao Xiaoyue and the others stood a little farther away, just in case.

"It turned out to be a tenth-order high-level chain array, brother, it seems that this time the two of us have to join forces again to get through this magic array. Chenxi looked at the study surrounded by enchantments in front of her, and her face was slightly solemn. He and his brother were only seventh-order high-level professionals, and it seemed impossible to break through this tenth-order high-level serial array at the moment. But if the two join forces, it will not be a big problem to take Qiao Xiaoyue and the others into the study safely.

"Well, of course! After entering the study, you will be responsible for protecting Tang Yulin and Song Xiaoyan, and I will be responsible for Qiao Xiaoyue and Xu Xiaoling. Yun Xi thought for a moment and said.

"No problem!" said Dawn with a smile. Then the two of them explained some attention to Qiao Xiaoyue and the others, and the group entered the tenth-order chain array on the periphery of the study. Of course, during the whole process, Chenxi and Yunxi walked in front, and the two kept deducing and calculating, teaming up to control the tenth-order chain array, and taking Qiao Xiaoyue and the others to move forward cautiously.

An hour later, the group finally arrived safely at the door of the study. Yun Xi and Chen Xi mobilized their spiritual power to carefully probe the situation in the study, and after finding that there was no danger, the two glanced at each other and took the lead in pushing the door into the study, followed by Qiao Xiaoyue and the others. As soon as the group entered the study, the door of the study closed by itself. Then the situation changed, and it was obvious that if you wanted to leave the study, you needed to re-calculate and calculate, and it would not work to go back the same way. Because they were not in a hurry to leave now, several people began to search the study to see if they could find any clues.

The whole study is very spacious, and at the entrance are two shelves, on which were originally placed two plates of flowers, but they have withered. Further inside is a large desk with some pen, ink, paper, inkstones, etc., and behind the desk are rows of bookshelves full of books.

Seeing this, the six of them acted together, Xu Xiaoling and Song Xiaoyan preemptively opened their mouths to check the places outside the bookshelves, Yun Xi and Chenxi, Qiao Xiaoyue, and Tang Yulin, the four little boys, had no choice but to check the rows of bookshelves to see if they could find any clues from them.

Two hours later, Qiao Xiaoyue and Tang Yulin sat on the ground, Qiao Xiaoyue gasped and said, "No, boss, we didn't find anything suspicious, and we didn't find any clues, can we rest for a while!" Although he is a cultivator, his cultivation is not too low, but his mental power is limited, and finding out if there are any clues hidden in those books is definitely a high consumption of spiritual power, and he really can't hold it.

Tang Yulin looked at the sky outside the window, and a trace of worry flashed on his face: "Captain, it's not early, and we have been busy all day today, so we're really tired." Do you think we can get out of this place first?"

Yun Xi and Chen Xi came to the two rows of bookshelves close to the wall where the two of them were, looking at the two people who were sitting on the ground without any image, Chen Xi smiled playfully and said, "I can't hold it for a short time, how can such spiritual power become a high-level alchemist?!"

Yun Xi glanced at the two people on the ground, then turned his head to look at Xu Xiaoling and Song Xiaoyan who had just come over, frowned and said, "Other places have been investigated, there is nothing abnormal, and no clues have been found. Now there are only these last two bookshelves left to be explored, everyone work hard, we will try to complete these two rows of bookshelves in half an hour, if there are no clues in them, then we will leave here first. ”

Hearing Yun Xi's words, Qiao Xiaoyue and Tang Yulin, who were originally sitting on the ground, and Xu Xiaoling and Song Xiaoyan, who came later, shouted at the same time: "I want to investigate this row of bookshelves next to the wall!" After speaking, the four of them glanced at each other, and at the same time turned their heads and began to investigate the row of bookshelves against the wall, only a few columns of books were placed in the middle of this shelf, compared with the bookshelf full of books next to it, the number of books was not even one-tenth of the latter, the four of them had a tacit understanding and ignored each other, and each began to find a place to start working. For the fact that they pushed the remaining huge workload to their captain and vice-captain, the four of them did not feel guilty about bullying the children at all.

Yun Xi and Chen Xi smiled helplessly when they saw this, and had to turn around and start to investigate the books on the remaining row of shelves.

After half a cup of tea, Chenxi walked up to Yun Xi with an ancient book and whispered: "Brother, look at this, according to the above records, the Valley of Death was still a desert before, but it became a fairyland-like place in the world in less than a hundred years after the Great War of Gods and Demons, is this too coincidental with the changes in Huacheng?"

Hearing Chenxi's words, Yun Xi thought about it for a while and said, "Well, you're right, there are indeed many coincidences between them. Moreover, from the geographical point of view, the 'Empty City' is located in the center of the Valley of Death and the Flower City, but the 'Empty City' has now become a dead city, which should have something to do with the changes in the Valley of Death and the Flower City. It looks like we're going to have to go to the valley of death on this trip!"

As soon as Yun Xi's words fell, before Chenxi could say anything, he heard Qiao Xiaoyue shouting loudly: "Boss, come and see, I found a strange thing, there is a very thick ancient book here, but it can't be pulled out, it seems to be glued to the bookshelf!"

Hearing Qiao Xiaoyue's words, Xu Xiaoling, who was standing not far from Qiao Xiaoyue, suddenly lit up her eyes, "Could it be that this book leads to some secret room?

Hearing Xu Xiaoling's words, Yun Xi felt uneasy in her heart, and hurriedly shouted: "Wait a minute, be careful of deceitful ......" However, before Yun Xi's words were finished, Xu Xiaoling's hand was pressed. Then, with a loud "click", the floor under the feet of the six people suddenly cracked, and the unsuspecting six people fell directly into the cracked gap between the bookshelves. And after the figures of the six disappeared, the study returned to its original state, as if nothing had happened.

In a large hall deep underground in the "Empty City", Yun Xi slowly sat up, rubbed the back of his head that hurt, and just looked around, he found that the other five people were lying not far from him, and just wanted to step forward to confirm the condition of the five people, Chenxi jumped up directly, rubbing his buttocks, and shouted: "Ah, my master's buttocks, it hurts to death!"

"Little brother, are you okay?" Yun Xi asked as he stepped forward to check the condition of the others.

Hearing Yun Xi's words, Chen Xi pouted and said with a look of grievance: "Something, something, how can it be okay!Brother, your brother and I are about to be thrown to death! Damn, who built this broken place, suddenly the feet were empty, and there was no time left for others to react, and I was hurt by the fall now!"

"It's so energetic and can scold people, it doesn't seem to be a big problem!" Yun Xi looked at the lively Chenxi and breathed a sigh of relief.

Hearing Yun Xi's words, Chen Xi pursed her lips aggrievedly, "People just don't care about anyone and no one loves them, my brother doesn't care about me! Hmph! Forget it, I have a lot of adults, so I don't care about you in general! By the way, how are Qiao Xiaoyue and them?"

Yun Xi stood up from Qiao Xiaoyue's side and breathed a sigh of relief, "There is nothing wrong with a few of them, they just fell and passed out, and they will wake up soon!"

Hearing Yun Xi's words, Chen Xi also breathed a sigh of relief, no matter what, this person was brought in by them, and he was also their teammate, if something happened, he and his brother were really to blame! Then, Chen Xi helped Yun Xi to lose some spiritual power of the life system to Qiao Xiaoyue and the others, and it didn't take long for Qiao Xiaoyue and the others to wake up one after another.

"Captain, vice captain, where is this?" Qiao Xiaoyue rubbed his head, which was still a little dizzy, and asked in a low voice.

"This is supposed to be the underground of the "Empty City", and my brother and I just took a general look around and it should be a dungeon. Dawn pondered for a moment and explained.

"What, Vice Captain, do you mean that we are now in the dungeon of the 'Empty City'?!" Qiao Xiaoyue and Tang Yulin said with shocked expressions. But having said that, when did the underground city of the "Empty City" appear in the underground, why have they never heard of it, such a big project, shouldn't be known to anyone!

"That's true, and judging from the buildings around us, this dungeon has definitely been in existence for a long time, at least hundreds of thousands of years old!"

"Just kidding, hundreds of thousands of years of history, doesn't that mean that this dungeon is likely to exist before the Great War of Gods and Demons! So, ...... here" Qiao Xiaoyue said with a shocked expression.

Hearing Qiao Xiaoyue's words, Chenxi didn't say anything this time, just smiled and nodded, affirming the guess in Qiao Xiaoyue's heart. Although Qiao Xiaoyue didn't finish his words, what Qiao Xiaoyue was thinking was basically written on his face, and he didn't have to guess at all. However, will there really be any treasures in this dungeon that has been stored for hundreds of thousands of years, and has been stored before the war of gods and demons?
