Sun Fei ran quickly, and soon came to the end of the road, and his eyes suddenly opened up.

A huge and incredible space appeared in front of Sun Fei's eyes, and at a glance, it gave people an illusion - it was like walking out of the corridor and leaving the labyrinth to the ground. I don't know how many times the space is huge, I can't see the edge when I look up, it's just pitch black, but with the help of the faint light that comes out of nowhere, I can see that thousands of meters away in front of me, there is a white pyramid-like tower with a height of five or six hundred meters, the diameter of the base is at least about a kilometer, the higher it goes, the smaller it gets, and it becomes a tip of less than one meter to the top, and the whole body is white, and there is a faint blue flame in it, which appears from time to time, and the whole scene has an indescribable eerie horror, which is very penetrating。

Hula——!

A chaotic elemental flame flickered, shooting out from the short-handled staff in Sun Fei's hand.

In the next second, the sound of fluttering wings came, and a huge crow with a black body and a wingspan of more than one meter suddenly appeared above Sun Fei's head, circled a few times affectionately, and landed on Sun Fei's shoulder, and then affectionately chirped softly in Sun Fei's ear, just like a child was coquettish with his parents, Sun Fei smiled and teased the crow, and then said a few words in a very mysterious language, the crow chirped happily, and then flapped its wings and flew, flying higher and higher, and soon disappeared into the darkness overhead.

The three white giant wolves also received Sun Fei's instructions, and quickly rushed into the distant space and began to search around.

Only then did Sun Fei begin to carefully examine everything in front of him.

This space is not dark, the white tower in the distance emits a faint fluorescence, and the ground under his feet has also cracked some fine and dense gaps, each of which is about a fist wide, and the width is very uniform, like a carefully woven spider web, these gaps are very deep, and there is a faint red flame coming out of it, which also provides some light for this mysterious empty space.

With the help of these faint rays of light, Sun Fei began to carefully observe this mysterious and huge space.

Soon he found that unlike the previous monotonous and simple Yongdao, there were finally traces of the existence of buildings in this space, and there were many huge stone pillars with a diameter of about ten meters on the ground, and there were some simple horizontal and vertical lines on these stone pillars, which were obviously carved by artificial gain, and the style of the stone pillars was also more complicated, some were diamond-shaped columns, some were cylinders, and some were square, each of these stone pillars was at least twenty or thirty meters high, and the complete one had at least tens of thousands of catties of weight, sparsely erected in the space, if you looked carefully, you would find that they were distributed in a very strange law, which just enclosed the terrifying white tower in the center of the space.

Sun Fei carefully observed these magnificent and huge stone pillars, and soon found something strange - all the stone pillars that fell to the ground were actually knocked down by some kind of huge force, some fell to the ground and then broke into several pieces, covered with sword scratches, and some of the scratches seemed to have been cut by the claws of some kind of animal, Sun Fei even found a few obvious fist marks on several stone pillars.

The stone quality of these stone pillars is very hard, Sun Fei has never seen it before, he transformed into a [Giant Bear State], concentrated all his strength on the stone pillar, the 21-level druid already has the strength of the three-star peak, and after transforming into the state of the bear man, the strength has increased by two times, that is, the power of the five-star initial level, such a power is already very amazing, to his surprise, this palm did not even leave a white mark on the stone pillar.

"This ......"

Sun Fei gasped, this discovery made him feel shocked in his heart, if he wanted to leave a fist mark on such a stone pillar, it seemed that he had to be at least a six- or seven-star master, who did this? And obviously, the swords and fist prints on the stone pillar were dense, and they were definitely not fought by the same person, which means that there were countless six- and seven-star masters who had fought here...... What the hell is this place?

With such doubts, Sun Fei continued to observe, and the more he looked, the more frightened he became.

Because on the stone pillars behind him, he found more traces of battle one after another, and some huge stone pillars were even directly knocked into two pieces by someone with a casual blow and collapsed to the ground...... If you want to cause such a trace, what level of master can do it? Moon-level powerhouse and day-level Venerable?

The complexity of the matter seems to be far beyond Sun Fei's imagination.

"Quack quack quack ——!!!"

Just then, the sound of crows chirping was heard.

Sun Fei's heart moved, and he switched his vision to the crow's body.

In an instant, I saw a craggy mountain rock appear in front of him, covering the entire top of the head, Sun Fei commanded the crow to fly thousands of meters from front to back, left and right, but the entire head was still boundless rock, like a huge rock dome upside down overhead - Sun Fei didn't guess wrong, this is still a space underground, or a huge mountain belly space.

I didn't expect that in the depths of Yongdao, there was such a strange place.

Sun Fei looked at the top of his head and the surrounding environment, and finally fixed his gaze on the magnificent white tower in the center of the space, maybe there were more clues here.

However, as Sun Fei slowly approached the white tower, he gradually realized that something was wrong.

The faint blue flame looming above the white tower did not have the slightest temperature, but it turned out to be ...... Sun Fei was shocked, walked quickly to the giant tower, took a closer look with the light of the armor, and was immediately stunned - where is this white giant tower, it turned out to be a mountain of dense bones, this tower of seven or eight hundred meters high is actually a mountain of white bones formed by the accumulation of countless white bones.

Sun Fei only felt a cool air rushing up behind his back, as if there was an invisible cold little hand gently caressing, his hairs stood up, and all the horror movies such as the old corpses in the mountain villages he had seen in his previous life rushed into his mind, such a big mountain of bones, how many bones would it take to pile up? I'm afraid that even if I slaughter thousands of human beings, I can't complete it, right?

After stabilizing his mood a little, Sun Fei watched carefully.

Who knows if it's better not to look at it, the more you look at it, the more frightened Sun Fei found that the bones piled up into this mountain of white bones are extremely hard, with Sun Fei's strength, he can't crush them, as if it is white refined steel, and the stacking of the mountain of white bones is very neat, and the layers of white bones seem to have been piled up one by one by someone's own hands, firmly rooted in the mountain of bones, full of the harmonious beauty of architecture and art, there is no slightest dust on the white bones, smooth as new, it is definitely not a natural formation, it seems to have just been built and piled up by artificial construction。

"Could it be that this white bone was built not long ago? Does that mean that there are other living people or creatures here?" As soon as this thought came out, Sun Fei was in a cold sweat again, he hurriedly circled around the White Bone Mountain, and did not find that there were stairs or anything like the Bone Mountain leading to the top, nor did he find that there were gaps or passages in the Bone Mountain, and gritted his teeth, Sun Fei switched to the perspective of the giant crow that was summoned, and then commanded the crow to carefully observe around the top of the Bone Mountain several times, but did not find any signs of the existence of any creatures.

"To build such a mountain of bones, it takes at least tens of thousands of laborers, and it is impossible not to leave the slightest trace, which is really strange......" After another hour, Sun Fei even climbed to the top of the Mountain of Bones to observe, but still did not find the existence of any living beings.

But in the process, he also made new discoveries.

This mountain of bones is not all made of human bones, Sun Fei found a lot of huge and incomparably large, more than thirty or forty meters of complete bones in the process of 'climbing the mountain', obviously some kind of giant creature left after death, although there is no complete skeleton on the mountain of bones, but in addition to these giant bones, Sun Fei also found a lot of bones that are not human physiological structure, some are extremely slender, some are too thick...... However, these skeletons have one thing in common, that is, the texture is very hard, and Sun Fei has not even found any bones that can be broken with his current strength.

There is only one explanation for this phenomenon -

The strength level of the owner of the skeleton must be far beyond the super master of the star warrior during his lifetime, only such a strong man can train the bones of the whole body to be harder than steel, even if the blood and bones decay after death, but the bones can be preserved for thousands of years, and will not become loose and fragile after decades like the bones of ordinary people.

This speculation made Sun Fei unbelievable.

In other words, the bones piled up into this mountain of bones turned out to be all the bones left behind after the death of some super powerhouses beyond one's imagination, but the question is, where to find so many super powerhouses? To pile up a mountain of bones of this scale, at least the bones of thousands of living beings are needed...... How is this possible, such a strong person, I am afraid that the number of Zenit countries can be counted with one palm.

This is simply a mound of the strong!

Sun Fei pulled out the bones of a two-meter-long scimitar-shaped mysterious unknown creature from the bone mountain, waved it twice in the air, and made a sharp sound of breaking the sky, and then jumped up and slashed down in the air, slashing on the stone pillar in the distance, and sparks like metal knocking appeared, stretched out his hand and wiped the bones in his hand, and sighed: "It's incredible, such a bone can be used as a weapon, if you can let the soldiers of Chambord City hold a piece of such a bone in their hands, it is comparable to any divine weapon!"

Sun Fei suddenly found that the value of these bones seemed to be not small!

Today is the beginning of winter, our hometown is a big festival, and I received a dinner with my school colleagues, so I had to go temporarily, saying that I wanted to meet this half of the cultural people, so I had to go.

Later.

I'm sorry, but I apologize for your pardon.
