Yuan Hongyi controlled the spirit boat to slowly fall from the position of the sky to the exit of the mountain wall without slowness, and then Yueru took out a nail-like thing and motioned for everyone to drop a drop of their own palm-sized nail.

"This nail is called the guide nail, it is a medium-grade treasure, you only need to drop a drop of blood on the nail, and then fix this nail on this mountain wall, you can determine the direction of this mountain wall through your divine sense, no matter where you go later, we can come back." Seeing that everyone was looking at the things in their hands with questioning faces, Yueru immediately explained to everyone the use of this guide peg, and used her spiritual power to cut her finger and drip a drop of blood on the guide peg, and sure enough, as soon as the blood fell on the guide peg, it was absorbed by the guide peg.

"It turned out to be a guide nail, presumably this is a new magic weapon refined by Si Dezhen, it's really powerful. When Yuan Hongyi heard that it was a guide nail, it was just refined by Si De Zhenren not long ago, and when Elder Lu Li talked to Si De Zhenren, he learned that he would come and tell Yuan Hongyi some ideas for refining the magic weapon of Si De Zhenren.

Sometimes it's not that the higher the destructive power of the magic weapon, the more powerful the magic weapon, so powerful that the refiner will start from several aspects, so that a magic weapon in addition to the high quality, but also pay attention to the magic weapon and other I function and practicality, in the past, the magic weapon that everyone refined was either an offensive magic weapon, or a defensive magic weapon, because the monk can do almost everything with spells, so there are not many functional magic weapons, but often in some cases, these functional magic weapons are of great effect, such as now.

Luo Lingjun dropped a drop of blood on the guide nail one after another, and then Yueru moved her spiritual power again, and nailed the nail into the mountain wall, which was next to the exit they had just come out of.

"Okay, where are we going next?" asked Yueru, clapping her hands and looking at everyone.

"Let's take a look around on the Lingzhou first, let's not go down below this underground world for the time being. Yuan Hongyi looked at it, and when he entered the endless mountains and forests in front of him, it was really not good to decide to go there.

"That's fine. Everyone nodded in unison.

Then Yuan Hongyi controlled the spirit boat to the side, all the way to the scenery of mountains and rivers, but there was no trace of any human habitation, until half an hour later, everyone calculated and found something different, it was a city, maybe it was still a monk's city, because there was a circle of translucent enchantments visible to the naked eye outside the city.

"I'm a god, but it's amazing, there are human monks here. Liu Hua let out an exclamation, no one would have thought that there really was a wise race in this underground world, everyone, you look at me, I look at you, and then look carefully into the city, it seems that there are still people coming and going, and there are still swords flying in the sky, which can be said to be very lively.

"I don't think there's much difference between here and outside, these people look the same as us, but their clothes are different from ours. Luo Lingjun poured spiritual power into his eyes and looked into the city, those monks were no different from the monks of the Upper Illusion Realm, maybe the only difference was the architectural style and clothing style.

"What now, let's go down and have a look?" Qin Xi felt that he couldn't keep looking here, and he just wanted to know if he could go down and take a turn.

"What nonsense is the senior sister talking about, the situation of these monks below is unknown, who knows what kind of cultivation they are, whether they are good or bad. Li Yuheng shook his head, feeling that he couldn't go on so rashly, who knows who these people are.

"You see that the gates of their city are also full of people, which means that their city is not closed, and there is more than this city, so we may be able to go in and inquire about the situation. Luo Lingjun observed carefully, motioned to everyone to look at the position of the city gate, and everyone saw that it was indeed full of people.

"It's so strange, why do they all rely on walking or driving a carriage or something after they come out of the city, why don't they fly with a sword?" Zhu Hanshu found that the people who came out of the city were still flying in the city one moment, and the next moment they came out of the city gate, they fell to the ground and began to use them.

"Don't say it, look at me. Qin Xi waved his hand, no matter how much he observed now, he couldn't know the truth of the matter, and he saw Qin Xi transform, and the Taoist clothes on his body were the same as those in the city below, a white and blue dress, which looked playful and cute.

"Senior sister, this method is a good method. Luo Lingjun knew what Qin Xi wanted to do at a glance, so he also changed himself, and the easy-looking yellow-white power suit on his body became moon white, and the clothing styles were all according to the monks who went out of the city gate below.

Then Xuan Chengye and the others did the same, all of them changed their outfits, and then Yuan Hongyi landed the spirit boat in a densely vegetated forest next to the city, and everyone officially fell to the ground.

"Don't talk casually for a while, let's go and see how the people here speak, I don't know if their language is the same as ours. Yuan Hongyi instructed everyone with his divine sense, and Luo Lingjun nodded hurriedly, wondering why the people in this city and this underground world exist in the secret realm.

Everyone nodded, and then cautiously walked in the direction of the city gate, a few people first came to the bushes near the city gate, wanting to hear what is different from these people in the past, but there was no surprise, they all understood what those people said, and it was the same as the illusion world outside, Luo Lingjun went around to the city gate with peace of mind, and then swaggered in.

"A few people, it's the first time you've come to Shanyuefang City, do you need a little old man for me to introduce you to the situation in our Shanyuefang City?" Luo Lingjun had just entered the city gate, and there was a little second child, with gray hair and beard, only a little taller than Qin Xi, and there was only one slit left in his smiling eyes at this time.

"How did the old man know that we were here for the first time?" Luo Lingjun was closest to the little old man, so he looked at Xuan Chengye and asked.

"Ahem, how many years has the little old man been here, I have never seen a few, naturally this is the first time to come, and our Shanyuefang City is located at the end of the world of the Upper Illusion Realm, and I know the little old man who usually comes and goes. The little second child looked Luo Lingjun up and down again, and made sure that he had never seen these young people, so he nodded and said affirmatively.

"Old man, what did you just say, this is the Upper Illusion Realm?" Luo Lingjun thought that he had heard it wrong, this underground world is also called the Upper Illusion Realm?

"Yes, could it be that none of your elders told you that the world we live in is called the Upper Illusion Realm?" the little old man frowned, feeling that Luo Lingjun was asking very strangely.

"Yes, yes, this is the first time we've heard of it. Luo Lingjun nodded hurriedly, although he still didn't understand in his heart, could it be that this underground world may have had dealings with the Upper Illusion Realm a long time ago, so it is called the Upper Illusion Realm, but I don't know when the two sides lost contact, but this is still a continuation of some of the past customs of the Upper Illusion Realm.

"Alas, I've read it in books, saying that our world should be connected to other times, does the old man know what the situation is?" Then Su Qifa pretended to sigh, and then tried to use the old man's words, casually nonsense, to see what the old man's reaction was.

"I see that you little guys are still young, and I need to explain to you the old man, you can't let the old man be in vain. The little old man saw that these young people didn't know anything, so he stretched out his hand and asked Luo Lingjun for a few benefits.

"What does the old man want?" asked Luo Lingjun tentatively.

"Thirty lower-grade spirit stones. The little old man looked at the colors of a few people and said, and then Luo Lingjun pretended to take out thirty lower-grade spirit stones from his sleeve, but in fact, he transferred thirty lower-grade spirit stones from his inner space.

Luo Lingjun handed the spirit stone to the little old man, and when he saw the little old man's smile on his face, he felt relieved, it seems that many things in this underground world should be similar to the upper illusion world, at least in terms of the circulating spirit stones.

"Hahaha, for the sake of you little guys being so sincere, I invite you to drink tea, old man, and give you a lesson by the way. The little old man smiled so much that he couldn't see his teeth, walked towards the inside of Shanyuefang City, and motioned for Luo Lingjun to follow.

Xuan Chengye secretly observed the little old man, and found that he was just a little monk waiting for me on the fifth floor of qi refining, so he didn't say anything and let everyone follow the little old man to a teahouse at the entrance of the street in Shanyuefang City.

The buildings of this Shanyuefang City are generally similar to the outside of the illusionary world, most of them are wooden buildings, but most of them are high-rise buildings, there are no single-storey houses, just like the teahouse in front of Luo Lingjun at this time, there is an eight-storey look, and the plaque above the gate reads "Shanyue Building" three big characters, looking at it I feel so angry.

"Old man Zhang is here again, do you want to stay in the hotel or drink tea?" The little old man had just taken Luo Lingjun into the teahouse, and immediately a shopkeeper stepped forward to greet him, and he was naturally very happy to see that the old man Zhang had brought so many people over.

"Drink tea, old rules. The little old man surnamed Zhang waved his hand to the shopkeeper, and then took Luo Lingjun to the second floor, and made a compartment inside, the environment inside was elegant, there were many futons placed in front of the long table, Old Man Zhang motioned for everyone to sit down at will, Luo Lingjun and Xuan Chengye sat next to each other, Luo Lingjun nine people plus Old Man Zhang was just enough to sit down.

"The old man will soon be with us. Luo Lingjun couldn't wait to look at Old Man Zhang.

"Hahaha, let's start with the strange suppression of our side of the world. Old man Zhang smiled and nodded, and then began to talk about some of the differences between this underground world and the upper illusion world outside.

"On our side of the world, if the monk is not in the defensive barrier, he will not be able to fly, whether it is flying with the sword or using the aura. Old man Zhang first told everyone about the phenomena that Zhu Hanshu saw on the spirit boat, and this was exactly where Luo Lingjun had a question.

"Why is this happening, is the sky suppressing us?" Luo Lingjun asked.

"It's not like that, it's all because our world is an underground world, and the sky in the sky is not really a starry sky, but a glowing roof. Old man Zhang looked up at the window and said.

"How come, isn't there a normal dawn and darkness here?" Su Qifa said this completely by setting up the old man's words, so that he didn't know if there was an alternation of day and night here, but logically speaking, this place is underground, relying on the luminous stone on the top to illuminate, there should be no alternation of day and night.

"What nonsense are you talking about, the alternation of day and night is just something that exists in ancient books, and not only does our world not alternate between day and night, but also does not change the seasons. Old man Zhang looked at Su Qi's words, and felt that this was someone's stupid child, who actually took those things in ancient books seriously.

At this moment, everyone determined that this place was really the underground world, and the entrance to the upper illusion world should only be the secret realm where the mirage appeared could enter this place, but everyone speculated that this underground world was also called the illusion world, indicating that there may have been a passage between these two places a long time ago.

"Then since everyone is a monk, but they can't fly, isn't it very inconvenient, so is there a teleportation array or something. Yueru had an idea, and followed Su Qifa's words and asked.

"Teleportation array? Do you mean the abandoned formations that exist everywhere? It's also seen in ancient books, all the teleportation arrays in our world can't be used, and now the places where these teleportation arrays are located are all old antiques, and they have existed for I don't know how many years. Old man Zhang touched his beard, thinking that these little guys might be disciples of some kind of sect, but they were too well protected, and they only knew to read some strange things from ancient books and jade slips.

Luo Lingjun listened to Old Man Zhang's words and couldn't help but look at me, let me look at you, since there is a teleportation array facility formation, it means that these teleportation arrays can also be used before, but I don't know why all of them can't be used now, Xuan Chengye secretly felt that it might be related to the fact that the monks here couldn't fly.

"What are you sacrificing?" Luo Lingjun heard that the people of this underground world used the base of the teleportation array to sacrifice, thinking that the upper illusion world outside would not sacrifice anything else except for what major things to sacrifice to heaven and earth, and there was no real heaven in this underground world, could it be that they only sacrificed to the earth?

"Naturally, it is to worship the great gods of Pangu and Nuwa. Old man Zhang looked at Luo Lingjun with a strange expression, what's the matter, how come these young people don't even know about Pangu and Nuwa, and what is going on with their parents, they don't even tell their juniors about this most important thing.
