The cracks in the earth are 30,000 feet deep, like a bottomless abyss.

When Gu Fei's feet fell to the ground, there was a faint trace of snow and frost on his eyebrows and hair, and the pitch-black ground was like hundreds of millions of years of cold iron.

"It's too cold!"

This is Gu Fei's most direct feeling, even him, his qi and blood are as strong as the ancient barbarian dragon, he feels cold to the bone, if it is an ordinary person, I am afraid that he has been frozen to the point that his soul is scattered.

The surroundings were pitch black, there was a trace of black mist swirling, every qiē was black, and with Gu Fei's eyesight, he could only see things within a radius of hundreds of zhang.

This is a dead and silent area, black stones are scattered on the ground, there are no living creatures, such a cold area, I am afraid that even the divine iron will freeze and crack.

No living thing can survive here, and this is a place where life does not fit in.

However, it is such a place, but there is an ancient pterosaur haunting, and there is definitely something here that attracts the primeval pterosaur that has been cut off by Gu Fei to entrench here.

"The Immortal Grass really grows around here. ”

Gu Fei really couldn't believe it, but the immortal elixir couldn't be looked at with common sense, this place, even the immortal gods were going to be frozen to death, and the terrifying Taiyin and cold qi was simply the best natural barrier.

Yan'er and Heitian must not go down here.

Even if there is a powerful holy soldier to protect him, I am afraid he can't, the cold air is pervasive, and the divine energy of the powerful holy soldier can hardly completely block the cold here.

Gu Fei did not hesitate and began to search the vicinity.

At this time, the people on the cracks in the earth were a little anxious, Gu Fei had been down for a long time, but there was no news back.

"Gu Fei, that guy won't have an accident!" Yan'er said worriedly, she stood next to the crack in the earth, looking down from time to time.

"Don't worry, how can anything happen to the boss?" said Hei Tian, he was still a little afraid of Yan'er, and he didn't dare to get too close to Yan'er.

The people of the Danding Sect will not only refine the elixir that can kill the flesh and bones of the dead and the dead, but also refine the terrible poison that is enough to poison the power.

In ancient times, there was a master who was good at the way of Danding, and was humiliated by a disciple of a major sect, and then, this master of Danding poisoned thousands of disciples of that sect, along with the sect master and elders, with a strange poison.

Obviously, Yan'er not only knows how to refine the elixir, but also inherits another terrible skill, that is, refining poison and using poison.

"Big brother, he has enough ability to protect himself, you can rest assured!" Xiaoqing said, but in fact, he didn't have a bottom in his heart, after all, this was in the ruins.

Baron didn't speak, his face still grim.

Under the crack in the earth, Gu Fei quickly noticed the traces left by the primeval pterosaur that he had beheaded the flesh, and many footprints of the primeval pterosaur appeared on the ground.

The rock beneath the crack in the earth was very hard, comparable to divine iron, but it still left all sorts of clues on the primeval pterodactyl.

Gu Fei followed the traces left by the primeval pterosaur and walked towards the depths of the cracks in the earth, and soon, Gu Fei felt something strange, he felt that he was heading towards the source of the cold air.

The temperature around him was getting colder and colder, and in the end, Gu Fei had to drum up the qi and blood in his body to resist the constantly invading Taiyin and cold qi.

Gu Fei's estimation was not wrong, under the crack in the earth, there was really a Taiyin leyline, and he was now walking towards the source of the Taiyin leyline.

He didn't know what was in front of him, so he took out the Nine Heavens Star Sword and held it in his hand, and then he hooked the power of the mountains and rivers to protect himself, and a faint and unreal ancient tripod loomed on Gu Fei's body.

In this way, even the great power of the world would not be able to kill Gu Fei with one blow.

The terrain below the cracks in the earth was undulating, full of rocks, without a trace of life, and Gu Fei found that there were more and more traces left by the primeval pterosaur.

After advancing for about a hundred miles, Gu Fei found that the terrain in front of him suddenly opened up, and the black mist formed by the cold air was gone.

In the area ahead, there was a bright light, and it was no longer pitch black.

"It's ......"

When Gu Fei walked into the area in front of him and walked up a hillside, he was immediately stunned by what he saw in front of him, his heart was shaken, and he couldn't speak for a long time.

"How could it be ......"

Gu Fei muttered to himself, only to see that there were two giant dragons thousands of zhang long lying in front of him, each of which was like a mountain in front of him.

To be precise, they were two dragon corpses that were intertwined, but they didn't have any life fluctuations.

The endless cold air came from a black dragon, and even the cold air emitted by the Taiyin earth veins under the earth was not as heavy as the cold air of this black dragon.

On top of the pitch-black scale armor, there was still a layer of black light circulating, the flesh and blood had not melted, and the blood was still vivid, as if it had just flowed out.

The other dragon that was entangled with the black dragon was a silver dragon, and the light of this area came from this silver dragon.

Both dragons were scarred, as if they had gone through a terrible battle, and then they both died under the cracks in the earth.

The silver giant dragon head has the horns of the ancestral dragon on it, and on the dragon claws on the abdomen, there are seven claws, this is actually a seven-clawed true dragon, and it is the royal family among the primeval dragon clan.

Gu Fei was shocked to the extreme, the seven-clawed true dragon, that is the legendary existence zài, even in Taigu, they are all strong men on the dominant side, but they have fallen here, how can this not make Gu Fei frightened.

And the black dragon is a little different, the dragon head is extremely hideous, at a glance it is not a good class, the dragon horn on the head is not the ancestral dragon horn owned by the dragon emperor, even if it has died for endless years, the evil aura that emanates from the dragon body is still terrifying.

"Could it be that this black dragon is actually ......?"

Gu Fei thought of a certain possibility, and then he was shocked, among the innate divine beasts derived from the primeval time, there were several evil dragons derived from the primeval fierce qi gathered, and then derived.

Such an evil dragon, although it is also an innate divine beast, but it is very different from the real dragon with the blood of the ancestral dragon, the primeval evil dragon is violent by nature, ferocious and terrifying, but wherever there is such an evil dragon infested the area, it will be a river of blood, and the lives will be ruined.

The black dragon that died with the silver dragon should be the legendary primeval cold dragon.

The primeval cold dragon, derived from the Taiyin leyline in the primeval period, this evil dragon, once born, only needs a breath of dragon breath to spew out, it can freeze thousands of miles and freeze a life.
