The most striking thing is that the spatial cracks are all over all the corners of the Yin Pass, and they are intricately intersected in an irregular manner, and the large gap can accommodate a cow, and the smallest place cannot even fly a bird. (・)

After Lin Feng fell into the Yin Pass, in the face of these chaotic and dangerous existences, he urged the flying magic weapon with all his strength to fall towards a place with a large gap, and the spiritual power left by Du Qiu Ming made it difficult for him to walk, every time there was a spatial crack that passed by Lin Feng, it would make him break out in a cold sweat!

With the five-zhang range of divine sense perspective, coupled with the restraint of the flying magic weapon on the downward trend, Lin Feng walked through the gap in the spatial crack without danger, and landed at a height of dozens of zhang for more than half an hour, and when his feet finally stood on the ground, a hanging heart finally calmed down.

The place where Lin Feng is located is a quiet hillside, and it is still a mountain, but it is very different from the mountains of Yangguan, there is no fire and rain here, so the peaks are generally very high, and the mountains are full of lush trees, which is diametrically opposed to Yangguan outside the first line.

Lin Feng took a deep breath, rejoicing that he had escaped death just now, thinking that if Du Qiuming knew that he could detect the spatial rift, he would definitely not have thrown him into the Yin Pass in the first place, it was better to let him fend for himself in the fire and rain of the Yang Pass, so that Lin Feng's survival rate would be even lower than in the Yin Pass.

Looking around, except for those ubiquitous spatial rifts, Lin Feng didn't find any other threats, which made him feel relieved, because in such a dense spatial rift, it was impossible for any living beings to threaten him. []

However, despite this, Lin Feng couldn't stay in the Yin Pass for long, although there was still a rain of fire in the Yang Pass, and Du Qiuming probably hadn't gone far, but there was no irresistible spatial crack. Although Lin Feng could detect these spatial cracks in the Yin Pass, he needed to consume a certain amount of spiritual power, so for the sake of safety, he had to get out of this place as soon as possible.

Lin Feng walked in the direction of Yangguan, and after climbing to the top of the mountain from the slope, he caught a glimpse of a tall mountain not far away, this peak was the highest among all the peaks, and strangely, there was a huge castle built on the top of the peak, and there was a majestic aura coming out of the sky above the castle.

Lin Feng was surprised in his heart, carefully observed the surrounding environment, and found that the peak where the castle was built happened to be in the middle of the mountains, and the surrounding peaks and peaks were scattered, as if they were very regular, one after another surrounded the castle, forming one natural barrier after another everywhere.

"There is actually a castle in the Yin and Yang Pass, this is a strange thing that I have never heard of, and in terms of the scale of the castle, it is comparable to any cultivator, in the Yin Pass where the spatial cracks are so dense, it must be that no one has entered this castle for a long time, so it may be an ancient ruin?"

Lin Feng thought to himself, his curiosity suddenly rose, and he immediately changed his attention, no longer moving in the direction of Yangguan, but walking towards the mountain peak.

The criss-crossing spatial cracks made Lin Feng suffer greatly, he sometimes bent down and lowered his head, sometimes stood sideways on tiptoe, and sometimes even had to lie down completely, crawling forward close to the ground, two hours later, he climbed over several mountains one after another, swallowed more than a dozen Hui Ling Pills, and Lin Feng finally came to the bottom of the highest mountain.

Looking up at the giant peak that reached into the sky, Lin Feng was surprised to find that there was not a single spatial crack in the range of about three feet around the giant peak, and this giant peak itself didn't seem to be naturally cast, it looked more like it was built by man, and the materials used in it, Lin Feng didn't even know it!

Such a huge peak, the construction materials used in it, you can imagine how amazing the amount will be, the most amazing thing is that these materials have been fused into a whole by the huge mana, and it is simply wishful thinking to take a piece from it, and even the vast and complicated Bailing Bamboo Slips have no records of this material!

Lin Feng couldn't imagine why the spatial cracks around the giant peak had stopped so neatly. Could it just be that the current situation has been formed by coincidence? Or is this giant peak actually able to make the spatial rift retreat!

No matter what, this giant peak revealed an unbelievable strangeness, so what would the castle at the top of it look like? With the doubts in his heart, Lin Feng drove the flying magic weapon to slowly spiral towards the top of the mountain, because there was no barrier from the spatial rift, the speed was naturally much faster, and after half an hour, he had successfully flown to the peak.

Standing on the top of the peak and overlooking it, the surrounding mountains float at the foot of the mountain like blooming lotus leaves, and the whole scene of the Yin Pass is in full view, which shows that the Yin Pass is not very big, and there is only this one of the mountains, and there is no other place besides this.

The mountain where Lin Feng is located is different from other peaks, not only is there a castle built on this peak, but the mountain peak is not naturally formed, even the material is not ordinary ore, and it is not as gentle as other peaks, but tall and straight, looking like a stone pillar erected vertically.

But at the top of this so-called "stone pillar", Lin Feng saw three big characters at first sight: Ancient Demon City!

As soon as he saw these three words, Lin Feng suddenly remembered that at the bottom of the valley of the Twilight Cloud Ghost Valley, the "Ancient Demon City" mentioned by the ghost-faced Rakshasa and the mysterious masked "Palace Master" was referring to the castle in front of him?

To Lin Feng's surprise, the aura on the giant peak was very strong, but not a single elixir was growing, and even ordinary flowers and plants were missing!

Looking from a distance, the entire Ancient Demon City was magnificent, and the buildings and pavilions were one after another, but there was no figure in sight, Lin Feng entered the city and took a closer look, and found that this Ancient Demon City was not like other castles, there were all kinds of defensive arrays arranged in the sky,

Except for the original spatial cracks, there were no prohibitions on the Ancient Demon City, and Lin Feng could even fly freely over the castle. Maybe those spatial cracks in the sky above the Ancient Demon City are its natural barriers, even if there is no defensive array, it is impossible for outsiders to want to enter.

However, there is a strange phenomenon, that is, there is no gate in a huge ancient demon city! When Lin Feng came in just now, he flew in close to the spatial rift above the ancient demon city, and the gap in it was only three feet, could it be that the monks of the ancient demon city could detect the existence of the spatial rift? Otherwise, how could they enter and exit the ancient demon city?

After looking at several places in a row, Lin Feng didn't see a single figure, this ancient demon city, which was bigger than the Qingdan Gate, has now become an empty city, judging from the style of various houses and the layout of the streets, the ancient demon city should be an ancient cultivator sect, but above the main hall of each house, there is a violent and terrifying demon body image!

Lin Feng felt more and more mysterious and weird about the Ancient Demon City, and he vaguely felt in his heart that the Ancient Demon City seemed to be a relic of the Ancient Demon Sect, and the fact that it could be built in the middle of the Yin Pass full of spatial cracks was enough to show that this Ancient Demon Sect must have great strength in the beginning.

All the houses were empty, and Lin Feng set his sights on the tallest building in the Ancient Demon City: a dome-shaped building that looked very much like a royal palace, and there was an angry golem on each of the four corners of the building.

Approaching this building, there were three big words "Ancient Demon Palace" written above the heavy door, Lin Feng pushed the door in, and a piece of dust fell from the top of the door, not caring about brushing the dust off his body, Lin Feng's eyes had already been attracted by the scene in the Ancient Demon Palace.
