The city of extreme cold was boiling, and everyone raised their heads to look north, and it was almost dusk. Three different colors suddenly appeared in the sky, the west was as blood-red as a flame, while the southeast was a blue and blue color, and the northern sky was particularly brilliant, and the colorful light curtain was like a giant jewel, gorgeous and colorful.

The old dog's rare face changed slightly, and he muttered in his mouth: "I didn't expect to have the opportunity to see the magnificent and gorgeous colorful aurora in my lifetime. ”

Ye Yinfeng and Ling Tianyun were completely attracted by the gorgeous sky, but they didn't hear the old dog's whispering. The scene in front of them gave them too much shock, they had never seen such a colorful and magnificent scene, Rao is that they have seen the scene of the white dragon breaking through the sky, and the scene of the heavenly gate is not so magnificent and colorful, the sky contained in the colorful halo is the fairyland, it should be said that the fairyland in the legend is not comparable to the colorful light curtain.

"What's that, why is it so loud outside?" Ye Yinfeng stared at the old dog with a puzzled gaze that showed excitement and obsession in his eyes. He had already heard a loud noise coming from outside the stone house, as if the city was boiling, and he had heard the excited shouts of many people. Why did the appearance of a colorful light curtain above the northern sky cause such a big shock.

"It is the seven-colored aurora, which can only be seen by people living in the far north, and this seven-colored light is said to only appear once in a hundred years. With the appearance of colorful light, there will be the landing of the glass exquisite heart, and if we want to leave the extremely cold city, we must rely on the glass exquisite heart. The old dog's eyes couldn't hide the excitement, and he replied to Ye Yinfeng.

"Why?" Ling Tianyun hurriedly asked when he heard this, he and Ye Yinfeng didn't know that there was such a thing in this extremely cold city, and no one had mentioned it to them.

"Don't ask, let's go check it out without further ado. I'll explain it to you slowly, and there are a lot of people heading north at this time, in order to find the glass heart that has landed. The old dog replied casually with the tackle in his hand.

Sure enough, many people in the city went to the north, and almost all the people in this extremely cold city rushed out. And Ye Yinfeng and Ling Tianyun were close behind the old dog, they didn't expect that there would be so many people in this Extremely Cold City, there were thousands of people pouring out like a swarm at this time, most of them were alone, and it was rare to see groups of people, if there were, it was the local indigenous people of the Extremely Cold City.

The curtain of colorful light above the northern sky grew brighter and brighter, as dusk was approaching, and the flame-red color of blood was also shrouded in the sky. No matter how intensely the blood-red remnant sun burned in the dusk, the light curtain hanging above the northern sky like a giant gem became brighter and brighter, although the colorful light curtain did not expand, but the brilliant and magnificent colors were more dazzling.

Except for a wall that was not too high in the southeast, there was no shelter in the northwest, and the strange stone houses began to become fewer and fewer as they went north. The Night Hades Palace is in the northwest of the Extremely Cold City, generally speaking, the scope of the Extremely Cold City is bounded by the main gate of the Night Hades Palace, and after crossing the straight avenue of the main gate of the Night Hades Palace, it should not be counted as the scope of the Extremely Cold City.

The farther north, the climate is getting colder and colder, and the remnant sun hanging in the west like a flame is also bigger, the burning fireball echoes with the colorful light curtain in the north, and the beating blood play light blends into the dark of the colorful light curtain, like a giant blood-red rope pulling the colorful giant gem.

Ling Tianyun and Ye Yinfeng didn't know how far they had gone, how long they had been walking, they only felt that the further north they went, the higher the terrain became, and the peaks of the mountains were like huge icebergs. The crystal light reflected the blood-red light from the iceberg, and at the same time, it also hung the colorful curtain of light in the sky, and the iceberg seemed to shrink everything in the sky, and then collected it into the hard glacier.

The sky was red and blood-red, but the mountains above the ground were a vast sparkling jade, and the peaks had already turned all the snow into hard ice. The ice glowed with a faint jade-like sheen, reflecting the colors of the sky, and the ice peaks and mountains seemed to be dyed with the colors of the sky. The magnificent colorful light curtain, which is emitting a colorful halo of glass, and the bloodthirsty sunset around the beating sunset like fireworks, all show the scenery of the Far North that is different from other places.

"Actually, this Extremely Cold City is an independent space, you can freely enter this Extremely Cold City from the outside, but you will be hindered from going out of the Extremely Cold City. There is a layer of diaphragm a hundred kilometers south of the Extremely Cold City, this layer of diaphragm cannot be seen, it is formless and colorless, but when you go south from the Extremely Cold City, as soon as you touch that layer of diaphragm, you will be bounced back by that layer of diaphragm. Do you think there are really people here who don't want to leave, but they can't leave, and they can't leave the Extremely Cold City. ”

The three of them, Old Dog and Ye Yinfeng, stood on top of an ice peak, and they had sunset down from near dusk to the remnant sun, and then the endless night began to shroud down, taking away the last trace of red and blood-red in the sky. They came to the seven-colored light curtain not far away, and at this time, the sky began to be filled with a gloomy night, and the seven-colored light curtain hanging above the sky was even more dazzling.

"In the far north, the night is often longer than the day, and if you count it according to the hours in the pass, it should be the time of Shen. The night here is nearly an hour earlier than Kannai, and the appearance of the colorful aurora will surely bring a fierce battle, so be careful then. The old dog instructed the two of them.

Looking at the incomparably bright colorful light curtain, Ye Yinfeng seemed to feel that the colorful light curtain was above his head, as if he could reach out and touch it. Listening to the old dog's words, he couldn't help but wonder: "What kind of thing is that glass heart, why can you pass through the boundary with the glass heart in your hand." What magical power does it have, sir? ”

"I've never seen that thing, but I've heard people say that the glass heart is actually a kind of stone, the whole body is as crystal as jade, containing a mysterious atmosphere, you will know it when you meet it. The appearance of the glass heart is difficult to describe, if it is a stone flower, it is more accurate. Like a flower but not like a flower, it is composed of multiple prismatic crystals that look like a stone flower when spread out. But no one has ever seen this thing, and it is not known whether it is correct or not. ”

When Ye Yinfeng and Ling Tianyun heard this, they couldn't help but look at each other, they had never seen or heard of this so-called glass heart, and listening to the old dog's meaning, without this glass heart, they couldn't leave the Extremely Cold City. But no one knows what this glass heart looks like, which makes them very confused.

"The Night Hades Palace has this glass heart, right?" Ling Tianyun thought of something, and he asked the old dog. If the Night Hades Palace did not have a glass heart, then how could Duo'er and the others come out of the Extremely Cold City, and he knew that there were still few people in the Night Hades Palace who went to the world to practice.

"The Night Hades Palace naturally has this glass heart, and there are quite a few of them. The people of the Night Hades Palace want to go out to run errands, so naturally this glass heart is indispensable. But you don't want to fight the idea of the Night Hades Palace, in the Extreme Arctic Cold City, the Night Hades Palace is the same, and the Night Hades Palace has a deep heritage, unless there are immortals descending, no one in the Extreme Cold City can afford to provoke the Night Hades Palace. When the old dog heard this, his face suddenly changed slightly, and he whispered to Ling Tianyun.

"Don't worry, we naturally know how many catties and taels we have, but seeing that Mr. is so jealous of the night Hades Palace, presumably the Night Hades Palace is not a good class." Ling Tianyun raised his starry eyes and asked the old dog again. He was very curious, what kind of ancient martial arts sect this Night Hades Palace was, compared to the other three ancient martial arts sects, this Night Hades Palace seemed to be more mysterious, and there was very little information about the Night Hades Palace.

"This is not entirely the case, at least there is no rumor of bullying in the Extremely Cold City, they have always been the principle that you don't offend me, I don't offend you. Moreover, there are heavy snowstorms in this extreme north at any time, but in the extremely cold city, a large array was laid down by the Night Hades Palace, which can greatly reduce the power of the blizzard, and it can be said that in this extreme northern place, the extremely cold city is the safest. The old dog couldn't help but stretch his tense nerves and explained to the two of them.

"In this way, the Night Hades Palace can be said to be the guardian of this extremely cold city. A large array was set up in the Extremely Cold City, but after we entered the city, we didn't feel anything, is this big array a void? When Ling Tianyun heard this, he immediately asked disapprovingly. When he heard the old dog's narration, he was even more puzzled, after he and Ye Yinfeng entered the city, they didn't see any magic circles at all, except for the stone houses of different shapes all over the city, and even they didn't feel any unique aura fluctuations in this extremely cold city.

Knowing that when they were in Changbai Mountain, the white dragon also brought bursts of aura fluctuations when it came out of the lake, and the rich aura was of great benefit to cultivation, and they could clearly feel it. But when they stepped into the Extremely Cold City, apart from the biting cold, they couldn't even feel the slightest aura fluctuation, so they were very skeptical of the old dog's words.

"You have just arrived in the Extremely Cold City, naturally I don't know, the stone houses are built by the Night Hades Palace, and the number is limited, when the number of people entering the city reaches a certain limit, the Extremely Cold City will be closed, and no one can enter the city. Don't look at the fact that there are still many empty stone houses, in fact, the number of people in the Extreme Cold City has not yet reached the saturation state, and if it has reached the saturation state, then the situation will not be like this. Don't have any doubts about the Hades, their authority is inviolable. ”

"In this way, there is another mystery in the stone house, so what is the special relationship between this local indigenous people and the Night Hades Palace? Why can't outsiders who enter the city hurt a native, could it be that the local natives have ever done something kind to the Night Hades. And it seems weird and elusive. Ye Yinfeng was also puzzled, and he couldn't help but raise his doubts to the old dog.

"Did you see, there are a lot of local natives in the crowd, and they are also here to find Liulixin." The old dog pointed to the crowd that was crawling all over the ice. And Ye Yinfeng and Ling Tianyun only noticed at this time that there was a group of people in the crowd who were dressed very differently, they were all simple animal skins, but their movements were extremely dexterous, like elves in this snowy peak iceberg.

"The local aborigines have an innate affinity for the glass heart, and it is easy for them to find the glass heart that falls from the sky. If they find the Glass Heart, they will hand it over to the Night Hades Palace, and every time the colorful aurora appears, 90% of the glass hearts are found by the local natives. You said that the Night Hades Palace should not be protected by the local natives, these natives are a treasure to the Night Hades Palace. ”

When Ye Yinfeng and Ling Tianyun heard this, their eyes showed an unbelievable look, they didn't expect that this mysterious city of extreme cold would actually have such a group of mysterious natives. It is an eternal truth that one side of the water and soil supports the other side, but the extremely cold city seems more and more mysterious in their minds.
