The Great Demon Envoy in front of him turned his back to us and said in a rather serious tone: "You can follow me all the way, don't act alone, don't enter other rooms without permission, no matter what movement, don't look around, otherwise you will be responsible for any consequences!" ”

Hearing this, although everyone was a little stunned, they still nodded.

Seeing everyone nodding, the Great Demon Envoy continued to walk forward, this retreat hall buried deep in the ground, only revealing a section of the roof, the area of the hall was a little more spacious than I expected, as I walked along the way, I found that the space on the first floor was enough to accommodate nearly a thousand people without looking crowded.

The downward road is a black staircase in the shape of a z-shape, along the way near the staircase, there is a dark stone door, the stone door is closed, I don't know what is inside, there was a warning from the great demon envoy before, our group did not go to check, worried about what prohibition exists on the stone door, it has come to this point, if it is because of curiosity to lead to any serious consequences, then it is a little more than worth the loss.

Walking all the way down, about a quarter of an hour or so, we can feel that we have come to the bottom of the retreat hall, on the stairs of this last layer, there will be a demon monk guarding almost a meter apart, and all of them are the peak powerhouses of the Immortal Emperor, which is enough to show how much the demon clan attaches importance to this place.

As I went deeper and deeper, the cold aura became a little more aggravated, and this phenomenon made me feel happy, because it proved that the Xuanjing Cold Flame was indeed in this retreat hall.

"It's here!" The faint voice of the Great Demon Envoy came, which immediately lifted everyone's spirits, only to see him stretch out his hand and push open a heavy black stone door, raise his legs and walk in, everyone looked at each other, hurriedly quickened their pace, and rushed in.

As soon as we stepped into the last room of the retreat hall, we habitually closed our eyes with the blinding bright light, but then we quickly opened them, and our eyes swept over the place, and our faces were full of surprise.

It was a huge, spacious and empty room, covering an extremely large area, almost larger than the one we had used before, and the whole room was empty without any special furnishings.

My gaze moved around, and after a while, it stopped at the center, where there was a huge hole about dozens of meters wide, and my eyes slowly moved upward, and my eyes suddenly narrowed, because on the ceiling of the room, an extremely complex formation was depicted, and with my attainments in the formation path, I couldn't understand it at all.

"Master, this kind of formation shouldn't belong to this interface......" The voice of the golden-eyed macaque sounded in my mind, and I was taken aback when I heard it, and I immediately thought of the mysterious person.

"Come with me!" The Great Demon Envoy looked around, waved at us, raised his feet and walked towards the central position, and everyone saw this scene and immediately followed.

As I got closer to the huge hole in the center, the cold aura became more and more intense, and my heart moved, could it be that the Xuanjing Cold Flame was in this big hole?

When the Great Demon Envoy was still about twenty meters away from the entrance of the deep cave, he stopped, and there were ten jade platforms as green as jade, forming a circle around the big hole in the center, and each jade platform was connected to the ground, which also carved extremely complex patterns, connecting the ten jade platforms together, and echoing the patterns on the ceiling.

"Let's all sit down on the jade platform!" The Great Demon Envoy pointed to the jade platform in front of him and said lightly.

Everyone was a little hesitant when they heard this, but Tianluo Jinxuan, who was beside me, pulled me without hesitation and trotted towards Yutai, saying as she ran: "Brother Lianfan, the two of us sit next to each other!" ”

Seeing that Tianluo Jinxuan was so positive, the others immediately dispelled the worries in their hearts, Tianluo Batian would not harm his daughter, right? Thinking of this, they each found a jade platform to sit on, and as soon as I sat on the jade platform, I suddenly felt a faint temperature spread all over my body along my buttocks, and even the cold air of the outside world seemed to be isolated.

Seeing that everyone was sitting on the jade platform, the Great Demon Envoy nodded with great satisfaction, and then with a wave of one hand, ten things wrapped in demonic qi flew towards us, and everyone reflexively grabbed it in their hands, and looked down to see that it was a jade bottle.

Before we could ask, the Great Demon Envoy took the initiative to explain: "This time, you are assisting the Demon Lord to impact the Void God Realm, it is definitely not something that can be completed in a short period of time, in order to ensure that in this process, there will be no failure due to the lack of demonic energy in your body, we have specially prepared a bottle of Nine-Rank Demon Qi Pill for each of you, each bottle contains three hundred pills, which is definitely enough for you to use." ”

After the Great Demon Envoy said this, he waved his hand again, and another ten jade slips flew into our hands, and then spoke again: "This is when the Demon Lord impacts the Void God Realm, you need to join hands to activate the part of the magic circle, you can have such strength in the Immortal Emperor Realm, you are definitely not those stupid people, I believe you will definitely be able to understand this part of the formation thoroughly in a short period of time." ”

"Lord Great Demon Envoy, how long will it take for us to attain enlightenment?" One of the Dharma Protectors asked.

"Three days!" The Great Demon Envoy said with a flat face: "After three days, the Demon Lord will immediately begin to attack the Void God Realm!" During these three days, you are not allowed to leave Yutai, let alone use your divine sense to explore the cave, I have a word first, if anyone does not listen to the advice, the consequences will be borne by themselves! ”

After saying this, the Great Demon Envoy turned around and left with the other four people without saying a word, and then heard the roar of the stone door closing, and the entire huge room was only ten of us, and it became silent for a while.

The people here are the best of the younger generation, all of them are some arrogant people, no one wants to say something first, and they begin to understand the jade slip in their hands, but there will always be accidents in everything, such as Tianluo Jinxuan next to me.

"Brother Lianfan, let's go to enlightenment together, and then share our experiences with each other!" Tianluo Jinxuan said excitedly.

Five minutes later...... "Brother Lianfan...... This formation is so difficult...... Can you teach me? Tianluo Jinxuan frowned slightly and said pitifully.

Ten minutes later...... "Brother Lianfan...... It's so boring, I don't want to go to enlightenment, let's play some other games, okay? Tianluo Jinxuan threw away the jade slip in her hand in annoyance, looked at me and said expectantly.

I saw very clearly that even Qian Moling, who had always been expressionless, the corners of his mouth were constantly twitching at this time, and in the end, in desperation, he directly reached out and popped out two balls of demonic qi, completely enveloping his ears, completely isolating himself from this noisy world, not only him, but several other people did the same.

I smiled bitterly in my heart, but said with a smile on my face: "Well, if you can understand the formation thoroughly before me, I will teach you to play a very interesting game, how about it?" ”

"Really?" Tianluo Jinxuan's eyes lit up and said.

"Of course it's true!" I smiled.

"Okay, you have to talk about it!" Tianluo Jinxuan said with a sweet smile, and immediately stretched out her hand, and the jade slip that was thrown away by her returned to her hand, and her divine consciousness quickly merged into the jade slip, and began to seriously comprehend.

I breathed a sigh of relief, wiped a handful of sweat that didn't exist on my forehead, and after smiling bitterly, I also began to comprehend, because I didn't dare to guarantee whether this thing was a test, or whether the Great Demon Envoy would test our enlightenment in three days, this mission is very important, and I will never allow any accidents to happen.

Strictly speaking, the magic circle in the jade slip is only a small part of the magic circle in the room we are in, but it is also obscure, but some people explain this part of the magic circle in a very easy-to-understand way in the jade slip, as well as various explanations, as long as it is a person who has slightly touched the formation path, it is not difficult to understand, and when it comes to the realm of the immortal emperor, everyone will more or less have some research on the formation, because the formation can be seen almost everywhere on the road of cultivating immortals, and if you don't understand one or two, I am afraid that you will suffer a big loss.

As everyone immersed themselves in the perception of the formation, the room fell silent again, and only the occasional faint sound of breathing could be heard.
