Xue Yi jumped into the cave. In the cave, a foul air came to my face.

Xue Yi held his breath and waved his hand again and again, and the cold breath came out, blowing the filthy qi in the cave out of the cave.

Xue Yi continued to look into the cave, only to see that there was nothing in the cave except for hundreds of pillars with a thickness of two meters.

But these pillars are not vertically upward, but horizontal, vertical, and oblique, arranged in a regular manner.

Xue Yi swept it away, and the way these pillars were arranged was actually arranged in the way of the dragon skeleton.

Xue Yi secretly wondered in his heart, who had formed such a huge dragon skeleton here? It seemed that this cave was more than 500 meters long, and if it was planned from the hole where the "dragon wings" were unfurled, the dragon skeleton would be more than 300 meters wide.

Moreover, such a huge keel model is arranged so regularly, and the proportions between various parts are just right, and there is no difference at all, which is what surprised Xue Yi the most.

Continuing to walk forward, jumping over one thick bone after another, Xue Yi came to the heart of the keel model.

From here, the thick bones around look extremely shocking.

Xue Yi's doubts increased even more, who was in the belly of this mountain to arrange such a huge keel model?

The soul swept around, and there were still no other living creatures, Xue Yi continued to walk forward, intending to go to the dragon head part.

But at this moment, his right side should be the dragon's stomach, and Xue Yi noticed the difference.

It's not empty like the heart, it's dozens of corpses.

Xue Yi flashed a few times. When I came to the corpses, I saw that the corpses had become fossils. From the appearance of the fossils, they were all human corpses. But the strange thing is that these corpses are all more than two meters tall, and their limbs are thicker than ordinary people.

Xue Yi was even more puzzled in his heart, looking at the faces of those corpses, although they were fossils, it could also be seen that they had been corroded by something, and the same was true for their limbs.

This was discovered. Xue Yi suddenly had a bold guess in his heart: this cave was not a dragon bone model, but a real dragon skeleton. And these corpses were swallowed into the stomach by this dragon. But for some reason. The dragon died, and these people didn't have time to be fully digested.

Thinking of this, Xue Yi's heart was already flooded with turbulent waves.

Of all the history books on the continent, the largest dragon has ever appeared. The length is only 100 meters. Dragons over 100 meters away have never been seen. And the skeleton of this dragon turned out to be more than five hundred meters long!

What kind of dragon is this? Where did it come from, and why did it die here?

All of this without a clue.

After a while, Xue Yi had no choice but to keep these in his heart and continue to study those corpses.

From the fossilized corpses, it can be seen that they are all wearing heavy armor, and after countless years, a small part of these heavy armor has been peeled off into pieces.

Xue Yi carefully picked up these heavy armor fragments, judging from the fossils. It is also impossible to tell what material these heavy armor are made of.

After a few moments, he flipped over a round stone the size of an egg.

Xue Yi studied for a moment. I don't know what it's for.

Putting the stone away, Xue Yi continued to rummage, wondering if he could find anything else.

Soon, he found several blood-red crystal-like things, similar in appearance to dragon crystals, but red in color as if they could drip blood.

Xue Yi didn't know about this, so he put it into the space and continued to rummage.

After a moment, a small sword more than an inch long was turned out. The small sword is golden and looks extremely small and delicate, like an ornament such as a pendant.

Xue Yi tried to inject dragon power into the small sword.

At this moment, a majestic thunder-attribute dragon power overflowed.

Xue Yi was horrified in his heart, threw the small sword, and hurriedly jumped in the direction of the cave entrance.

But even with his speed, before he could escape two steps, above the golden sword behind him, a pillar of fire attribute light burst out.

As soon as the light appeared, it quickly became hundreds of times thicker, and then soared into the sky.

Xue Yi's figure was undoubtedly engulfed by the pillar of light, and the feeling of his body being torn apart came. A sense of despair that I had never felt before rose from the bottom of my heart.

The energy contained in this pillar of light was a hundred times more powerful than the full force of the dragoon's blow. In the face of such a powerful force, Xue Yi had no chance of surviving at all.

Outside the mountain, the ice and snow dragon was bored, and suddenly felt a huge momentum coming, it instinctively flapped its wings, and instantly retreated seven or eight hundred meters.

At this moment, a golden pillar of light rose from the top of the mountain. The whole mountain collapsed at the moment when the pillar of light rose to the sky, and the rubble rained down.

But before the rubble could roll down, it was involved in the periphery of the golden light and turned into ashes.

Within a radius of fifty miles, under the involvement of the pillar of light, it turned into a scorched earth.

The ice and snow dragon was bombarded by the shock wave when the pillar of light soared into the sky, and was directly shocked out more than fifty miles away. The Ice and Snow Dragon hurriedly used its spiritual power to form a layer of cold aura on the surface of its body, so as to avoid injury.

The soldier and the natives were protected by the light shield and barely hurt, but the two of them were now tightened in their chests, and they spat out a mouthful of blood in unison.

The two watched in shock as the entire mountain disappeared in less than half a second, their mouths stammering, their minds blank.

At this time, because the ice dragon was too anxious, he actually spat out his mouth and scolded: "Stupid!" Ignoring the aftermath of that pillar of light, he flapped his wings and flew in the direction that Xue Yi had just entered the cave.

More than eighty miles away, the soldiers of the Sea Dragon Empire heard the roaring sound, and hurriedly looked up, only to see a thick golden pillar of light rising into the sky, and a circle of shock waves visible to the naked eye spread, which was extremely conspicuous in the blue sky.

The president of the Sea Dragon Empire shouted to the soldiers: "Strictly guard the camp, I'll go and have a look." ”

Without waiting for the sergeants' advice, he had already straddled his horse and left. Behind him, a juvenile dragon about four meters long followed.

At this time, the ice and snow dragon had already come within a hundred meters of the mountain just now. The smoke and dust from the collapse of the mountain had not yet dissipated, and even with the eyes of the Ice and Snow Dragon, it was impossible to penetrate the smoke and dust.

The Ice and Snow Dragon was already in a great hurry at this time, and its soul was spreading, within a radius of tens of thousands of meters, all in its mind.

Under this sweep, there was not a single living creature within a radius of 10,000 meters. The ice dragon roared in rage, spewing out a breath of icy cold. As soon as this icy cold breath came out, the surrounding smoke and dust rolled and spread out to both sides, revealing the location of the mountain just now.

I saw that there, the mountains within a radius of a hundred miles had long since disappeared, and above the sky within a radius of a hundred miles, there was a fiery red luminous body suspended there. This luminous body is translucent, and through the outer layer, you can see that inside the luminous body, Xue Yi is standing there quietly.

The Ice Dragon was first overjoyed that this kid was not dead, and then shocked that when he had just scanned it with his soul, there was clearly no living thing here.

The ice and snow dragon was surprised, and its soul probed Xue Yi again. The result was the same as before, he obviously saw Xue Yi floating there, but after his soul swept over, he couldn't sweep anything.

At this point, the luminous body gradually fades away. Within the luminous body, Xue Yi was intact. And the stone he had just put into the space was floating silently above his head. It was precisely because of the fiery red light shield inspired by this stone that he was able to carry that earth-shattering blow.

Xue Yi was afraid for a while, the golden little sword just now turned out to be an offensive weapon, and this stone was a defensive weapon. If it weren't for the defense of the light mask inspired by this stone, I'm afraid he would have been blown into ashes long ago.

Xue Yi learned a lesson from this incident, and he didn't figure it out in the future, don't touch other people's things.

At this time, the fiery red light shield of defense permeated Xue Yi's body, and Xue Yi was indescribably comfortable. Suddenly, his mind shook, and a lot of information poured into his mind.

He could feel it coming from the stones above his head.

It turns out that this stone is called the Fire Refining Stone, which is a naturally formed stone, and it is formed by the extremely strong fire dragon knight pouring dragon power into it, and it has extremely strong defensive power. Each time it encounters a high-intensity attack, the Fire Refining Stone will be activated, automatically forming a defensive light shield.

This shield not only prevents attacks of high intensity, but also ignores soul detection.

And there is another point, because this fire refining stone is formed by the extremely powerful dragon knight with dragon power injection, and every time the fire refining stone is activated, a large amount of dragon power will be released. And those who are in the light mask, tempered by this dragon power, will greatly enhance their physique.

Knowing this, Xue Yi felt it, and sure enough, the dragon power that was originally in a saturated state in his body actually had at least half of the gap at this time. Xue Yi could feel that now his dragon power was on the verge of breaking through.

Xue Yi was overjoyed in his heart, if he did it again, wouldn't he be going to break through again?

However, this fire refining stone is not used indefinitely, its lifespan is ten times, and it has been used seven times before, and this time it is eighth. In other words, Xue Yi can only use it twice at most in the future.

With a slight regret in his heart, Xue Yi put the fire refining stone into the space, and the fiery red light mask disappeared suddenly. Xue Yi jumped out of thin air and jumped onto the back of the ice and snow dragon.

The ice dragon opened his mouth and shouted, "What's the matter? The whole mountain is gone? You're playing too big, aren't you?"

The little soldier also turned into joy at this time, and said: "It's okay, it's okay, it's okay, the power just now is too scary." ”

Xue Yi didn't answer, and there was a slight smile on the corner of his mouth very rarely. Then he said to the Ice Dragon, "Go to the camp of the Sea Dragon Empire." ”

Seeing that Xue Yi didn't answer, the Ice and Snow Dragon couldn't help but shake its huge head, obviously depressed, and then turned its head and flew towards the direction of the Sea Dragon Empire's camp.

But at this moment, Xue Yi's soul swept away, and four thousand meters away, a person rode a horse and galloped, and behind him, a green dragon flapped its wings and flew at great speed.

Tomorrow's four watches. (To be continued......)
