The ancient city of Cangyu was built on a huge mountain range that stretches for millions of miles, and the trend and situation of this mountain range is a divine dragon entering the water, and the ancient city of Cangyu is built on the dragon head of this divine dragon, the highest peak.

A long time ago, such a terrain was a treasure land of feng shui, and it was a secret feng shui place that did not show mountain dew, so the Cangyu Dynasty was prosperous, and the people were rich and monks, but then the dragon vein was destroyed, and most of the peaks in the ancient city of Cangyu also collapsed, and more than half of the land was submerged in the sea.

Now, Du Feiyun and Yanyunzi are standing in front of the cliff break, and the cliff is the gap where the ancient city of Cangyu collapsed and broke at the beginning.

If you go down, you will enter the broken wall, where there is a dark and endless abyss, I don't know how deep it is, and I don't know where it leads. Du Feiyun, Yan Yunzi and the others thought about it, and then decided to go up and enter the Cangyu Ancient City first, to explore the number and condition of the Heavenly Demons in the city, and if they could get out of the city, they would go down into the ruined wall to explore the ancient teleportation formation under the Cangyu Ancient City.

If you want to ask Tiantian to learn smart this time, he knows that Du Feiyun, Yan Yunzi and Wu Yazi are the same heart, so he will not express any opinions at all, he is really good, so as not to make the three of them unhappy.

In order to be on the safe side, to cover his ears and eyes, and not to attract the attention of the heavenly demons, Du Feiyun asked everyone to follow him into the storage space in the Nine Dragons Ding. Then he harnessed the Nine Dragons Ding, turning into a speck of dust and approaching the canopy.

Still as I saw last time in the Yongning Mountains, the gray canopy was filled with the aura of decay and aging, and any monk and magic weapon would be corrupted and eroded after being contaminated, unless it was a magic weapon that could change time and space. to be able to resist.

Near the canopy, tens of thousands of heavenly demons were surrounded, and they were like a circle of swirling smoke, protecting the canopy around it, and defending the safety here with their lives. However, it is a pity that they did not perceive the approach of Jiulongding, and this speck of dust is almost impossible to see with the naked eye. Even spiritual discernment is almost impossible to see.

What's more, Du Feiyun also used the few Heavenly Demons he had captured before as a disguise to turn them into his puppets and release the aura that belonged to the Heavenly Demons. The Nine Dragons are completely covered and hidden. So the Nine Dragons Ding came to the side of the Heavenly Curtain smoothly, and Du Feiyun launched the Nine Dragons Ding again, and began to devour the refining of the Gray Heavenly Canopy, devouring the amount of time power in it, and the Nine Dragons Ding also got great benefits.

Soon, the canopy was swallowed up to a slight gap, and the Nine Dragons flew in, and then the canopy was restored again, and there was no trace at all. The Heavenly Demons who were guarding had no idea that someone had already gotten in under their noses.

After entering the Cangyu Ancient City, Du Feiyun still didn't dare to relax, didn't let everyone leave the Jiulong Ding, and continued to stay inside, while he drove the Jiulong Ding and began to wander around the ruins of the Cangyu Ancient City, observing the situation everywhere. In order to avoid being detected by the Heavenly Demon powerhouse. He did not dare to extend his spiritual sense, and many times he observed it with the naked eye.

The ancient city of Cangyu is indeed as he expected, extremely desolate and dilapidated, many buildings have been invaded by tens of thousands of years, etched by wind and frost, and basically have been corrupted and dissipated, leaving only a few huge stone piers, city wall bricks and floor tiles, etc. I can still vaguely recognize the scene of that year.

Unlike outside the canopy, where there were hundreds of thousands of Heavenly Demons roaming, it was rare to see the existence of Heavenly Demons inside the Heavenly Canopy, even after Du Feiyun walked around the city, he only found less than a thousand Heavenly Demons in these two hours. These thousands of Heavenly Demons are still guards, but each of them is a Green-Eyed Heavenly Demon. All have the strength of the Soul Refining Realm. Fortunately, Du Feiyun was cautious and cleverly disguised, so he was not discovered by these green-eyed demons. ...,

When they hadn't entered Cangyu Ancient City before, they thought that there would be more than a million Heavenly Demons gathered in the city, but now it seems that this is not the case. Could it be that the Heavenly Demons who came to Cangyu Ancient City were only the more than a thousand green-eyed Heavenly Demons here, and the hundreds of thousands of red-eyed Heavenly Demons on the periphery?

This is obviously impossible, everyone will not believe it, so Du Feiyun immediately thought of a greater possibility, that is, there must be hundreds of thousands of heavenly demons here, but they are not in the city now, so it is very likely that they are going to open the spatial passage.

Just like the last time in the Yongning Mountains, Du Feiyun, Yanyunzi and Wuyazi all thought of this, so they all looked at the earth under their feet. According to the confession of the Heavenly Demon captive, there is an ancient teleportation formation in the depths of the underground of Cangyu Ancient City, so Du Feiyun guessed that this teleportation formation is likely to lead to other spaces, which happens to be used by the Heavenly Demon Army, and then the teleportation formation will be repaired or transformed, so that more Heavenly Demon Troops can drive straight into the Eastern Wilderness.

Thinking of this, the four of them no longer hesitated, Du Feiyun manipulated Jiulong Ding, and hurriedly dived into the depths of the ground, diving all the way to see what was going on. Of course, just in case, he fell into the encirclement of hundreds of thousands of heavenly demons, he was extremely cautious, and the speed of his dive was not hurried, always paying attention to the movements around him.

Finally, a quarter of an hour later, Du Feiyun realized that he had dived into the depths of ten thousand zhang, but there was still darkness all around, full of endless rocks and sand, where was there any teleportation formation?

Du Feiyun pondered and meditated, and he didn't know what was wrong with the road, so he frowned and looked around, Yanyunzi was also anxiously trying to find a way, and Wu Yazi asked tentatively: "Could it be that you need to enter from the formation in the Cangyu Ancient City to find the existence of that formation?"

Wu Yazi's proposal suddenly made the eyes of both of them light up, and Du Feiyun suddenly patted his thigh and said, "Yes, how can I ignore this? If you can find it by diving into the ground like this, then the secret of the formation under the ancient city of Cangyu is not a secret." ”

So, the four of them hurriedly returned to the ground and began to search in the ancient city of Cangyu. Du Feiyun first took a look at the distribution location of the thousands of green-eyed heavenly demons, and sure enough, he found that near a low mountain range in the north of the city, the number of green-eyed heavenly demons gathered was the largest. A closer look showed that the more than 300 Heavenly Demons guarding there were actually scattered around the low mountain range with some kind of regularity, faintly defending the mountain range.

Before, Du Feiyun only cared about finding out if there were a large number of Heavenly Demons in the city, and ignored this detail, but now looking at the more than three hundred Heavenly Demons, it seemed that they had formed a guardian formation to protect the low mountain range. Moreover, after going to the low mountain range to explore, he decisively found that there were many broken tiles and glasses in the mountain range, as well as a large number of stones and stone piers, which were obviously not mountains, and it was estimated that it was a majestic building tens of thousands of years ago.

Now that he has a clue, then the next thing is much easier, Jiulong Ding quietly sneaked into the low mountain range, and finally found a dark passage hidden in the depths of the earth, and along the dark passage all the way down, you can meander towards the lower part of the earth, and gradually enter the depths of the earth.

At the entrance of the dark passage, there were heavy guards, and there were thousands of green-eyed demons, and the four of them were startled when they saw this scene, and thousands of green-eyed demons gathered in such a small cave, they must have been discovered in the past. So Du Feiyun made a little trick and released eighteen Shura phantoms, wandering back and forth in the Cangyu Ancient City above, stirring up the wind and rain.

The eighteen Shura phantoms were very powerful, and the green-eyed heavenly demons were definitely not opponents, and soon set off a bloody storm in the city, wailing, and the thousands of heavenly demons at the entrance of this dark passage immediately got the news, and immediately fell into a short period of chaos, and then sent more than three hundred green-eyed heavenly demons to the city to support. ...,

It was in the short moment of the commotion that Du Feiyun keenly seized the opportunity to let Jiulong Ding sneak in quietly. Finally succeeded in entering the dark passage, everyone was secretly relieved, at this time, the troublesome eighteen Shura phantoms gradually dissipated, and the three hundred green-eyed heavenly demons who rushed to support pounced, and were immediately full of anger and resentment, and slashed the heavenly demons who sent a message for help.

The passage was very dark, but the four of them were all strong monks, even if they closed their eyes, it was like day, their hearts were bright, and they could see everything around them clearly. The passage was only a zhang wide, but it was very dry and tidy, and the walls around it were as smooth as mirrors, and it was evident that a great deal of effort had been taken to carve and polish them. It can also be seen from this that this passage should not be the passage of some official eunuch or the royal family's treasure room in Cangyu Ancient City, and it must be an extremely important and confidential route.

Finally, after a quarter of an hour of advancing towards the lower part of the road, the group finally reached the end of the passage, and there was no road further down, but a huge abyss of darkness and emptiness. But now, the huge abyss was not dark, but shining tens of thousands of green points of light, among which there was a monstrous demonic aura and a dead ash aura coming out, and the four of them immediately stopped in place when they saw this scene, and even their heartbeats seemed to stop.

Because, in the turquoise abyss reflected by green light, there were tens of thousands of green-eyed heavenly demons. Of course, this is only one of the reasons, and the other more important reason is the real reason that shocked and amazed the four of them.

In the center of the abyss, there is an extremely prosperous and huge altar, above the altar shows a brilliant brilliance, there is a huge hole, the hole shows the scene of the extraterrestrial starry sky, behind the hole is an ancient road full of starlight, I don't know where it leads.
