The source of the underground dark river, a mysterious lake, after the huge waves, only to see on a green and secluded water surface, suddenly, a huge head emerged, like a snake but a little like a deer, on the head, there are two horns, it has been completely turned into dragon horns, there are long whiskers under the jaw, at first glance, it is really majestic.

"This ......... How is that possible?!"

Cheng Fei was stunned and looked at the huge head that suddenly appeared on the surface of the turbulent cyan lake, and couldn't help but exclaim in his mouth, and between his words, he was full of disbelief: "There really is.......... Dragon!"

Although, from the moment he received the task of slaying the dragon, he had been prepared in his heart, but at this moment, when the dragon really appeared in front of his eyes, it was a completely different feeling.

The cold front with damp water vapor rushed to his face, but it brought a strong fishy smell, and invisibly, a terrifying dragon power diffused, making Cheng Fei's expression suddenly tighten.

Although he was full of disbelief, the cruel truth was in front of him, and he couldn't help but believe it, and the question now was not whether he believed it or not, but whether he .......... How do you deal with the unfriendly-looking dragon in front of you?

Just when he was stunned for a moment, a huge cyan dragon slowly appeared on the surface of the water, its lower body coiled, the dragon body soaked in the lake water, Cheng Fei was less than half the thickness of the huge dragon's body, but only the upper body and the dragon head of the cyan body gathered and stood in the air, and it was even more than ten meters above the ground, exuding a faint golden light, and at this moment it was looking down from above, looking at Jiang Chen, who was like an ant to it!

"Damn, there's a dragon living at the source of this underground river?"

Generally speaking, a powerful water beast like a dragon would only inhabit rivers and seas, and at the very least, there should be a lake, but he had never heard of something as deep underground as this.

"Could it be an earth dragon?"

The corners of Cheng Fei's mouth couldn't help but outline a wry smile, and at the same time, when he turned his hand, Chijing manifested, and a three-foot long knife was in his hand, and the qi and blood in his body had reached an unprecedented peak.

"Roar!"

The huge head of the cyan dragon suddenly raised its head to the sky, and a low dragon groan erupted, and the huge sound wave vibrated so that people's eardrums couldn't help but feel pain.

The moment Cheng Fei held the knife in his hand, he instinctively felt an indescribable terrifying danger, there seemed to be some terrible danger in the rear that was rapidly approaching, with the innate instinct in the depths of the human blood, he almost didn't think about it, he drank in a low voice, the qi and blood flowed, the internal gang exploded, the speed increased by no less than ten times, the whole person's body moved sideways, and above the water surface, a series of afterimages were suddenly dragged out.

At this moment, above the underground lake, a huge wave was set off, and then a huge tail broke through the water, went straight into the air, and smashed down, bringing a terrible gust of wind, which almost made Cheng Fei, a top master of cultivation, feel a little unstable.

"Roar!"

There was another roar from the monstrous waves, it seemed to warn the other party not to approach it, and the thick hostility came from the lake, making Cheng Fei couldn't help but be stunned.

"Although this thing looks like a dragon, it doesn't seem to have the magical powers of the legendary dragon, uh......... This guy can't be a Xibei, right?"

After all, in Cheng Fei's cognition, the dragon is a legendary divine beast, born with boundless magical powers, which can resist water and thunder, spread clouds and rain, and control the weather at four o'clock, comparable to the immortal gods.

But now it seems that the one in front of him does not look like the legendary almost omnipotent dragon, but a mutated big snake, although it has a slightly atavistic appearance, but it is not enough to be regarded as a real dragon.

Of course, all this is just Cheng Fei's conjecture.

It's a pity that before he came back to his senses, the huge tail of the cyan dragon smashed over again, but unfortunately the thing was too noisy and couldn't get close at all, so it was easily dodged by Cheng Fei, and even Cheng Fei's clothes couldn't touch it.

However, the strength of this guy is so great that it is enough to make people frightened, and at the moment when Cheng Fei dodged the giant tail attack of the cyan dragon, there was an earth-shattering roar below, and a terrifying wave dozens of meters high suddenly rose into the sky, looking at the majesty, it was really shocking.

"Damn, this guy is so powerful, even if he is not a real dragon, but with this huge dragon body that resembles a divine dragon, in this water, I am not its opponent!"

After shuttling through several adventure worlds, Cheng Fei can be regarded as a well-informed person with his conceit, but he can't help but be amazed at this moment, but this cyan dragon is obviously not very kind to himself, and he is thinking about how to put himself to death. Especially the strength of the tail, if you smash it, it is estimated that the Buddha and Demon who have cultivated to the Dacheng realm will not be able to bear it, after all, he has not reached the peak of the Demon Buddha Golden Body after all, and he has become a Buddha and Demon Immortal.

"Roar!"

Seeing that he smashed dozens of times in a row, he was stunned that he didn't hit Cheng Fei, below, above the water, the cyan dragon held his head high, a pair of huge dragon eyes glowed with a faint golden light, staring at Cheng Fei in mid-air, a big mouth was full of mist, the hideous fangs emitted a trace of cold light, and roared violently......

"Boom!"

Above the water, the huge waves surged, and the terrifying water columns rose from the ground, and the huge waves roared, like ten thousand horses galloping, and the water columns supported the sky, all of them roared, and rushed straight to Cheng Fei.

"Damn, this guy doesn't seem to be completely ignorant of dragons!"

Cheng Fei couldn't help but curse secretly in his mouth, and with a wave of his hand, the Chijing long knife slashed out, bursting with qi and blood, and poured into the inner gang, and actually split out a terrifying knife that was more than ten meters long, and slashed violently on the more than a dozen huge water columns.

"Boom!"

In an instant, the entire cyan lake seemed to be boiling, and Cheng Fei's body was like electricity, and in an instant, he had broken through the huge waves and fled towards the dark river.

Don't look at Fang Cai's blow he showed so violently, but such a high-intensity attack is too huge a load for him, and if he continues to fight, I'm afraid he hasn't killed the cyan dragon yet, and he will have to run out of energy first.

Escape!

At this moment, all he can do is to run for his life and escape as fast as possible in his life. Behind, the cyan dragon roared like a madman, and immediately set off to chase after it, and for a moment, the water waves were surging, stirring the entire underground world.

"Compared to strength, maybe not as good as you, but compared to speed, you are far worse than me!"

Seeing the cyan dragon chasing after him, Cheng Fei let go of his speed with all his might, and the whole person was like an aurora lightning, quickly fleeing along the way he came, and soon, the cyan dragon was left far behind him.

"Boom!"

Passing through the dark hole, breaking into the waterfall pool, and then, Cheng Fei quickly swam upstream, accompanied by a loud noise, and between the splashes of water, his whole person had already jumped out of the water and landed on the shore.

After a short pause, sensing that there was no danger in the pool, Cheng Fei finally breathed a sigh of relief, but at this time, he seemed to notice something, and suddenly shouted in his mouth.

"Something, dare to peep at me!"

The words fell for a moment, and then, his whole person suddenly jumped into the air, and actually rose into the air, like a big bird, and glided out of the air for sixty or seventy meters, and then, the red crystal long knife in his hand dragged out a chilling knife light, and fiercely slaughtered towards a big tree not far away.

"Poof!"

Five or six people hugged the thick tree and were cut in two, revealing a cyan fierce wolf with a height of one foot and two big eyes like copper bells, revealing two terrifying blood-colored red lights!

"It's a wolf?"

With a loud shout in his mouth, Cheng Fei moved the Chijing long knife, the sharp sword flashed, and in mid-air, it was like a blood-colored horse galloping, whistling and piercing the air, and disappeared in a flash.

Although the giant wolf is fierce, it is just a beast with no wisdom after all, how could he have expected Cheng Fei to shoot so fast, even if it is a fierce beast that is known for its speed, but before it can react, it has already been slashed by Cheng Fei's Chijing long knife.

"Roar!"

Even ordinary beasts will become ferocious because of madness after being injured, let alone such a huge fierce wolf, after the giant wolf was injured, it immediately became fierce and abnormal, and with a roar in his mouth, he didn't care about the injuries on his body, and grabbed Cheng Fei's knife-holding arm with one claw.

"The mantis arm is a car, not self-sufficient!"

Cheng Fei snorted coldly in his mouth, ignoring the giant wolf's attack, Nei Gang urged, poured into the Chijing long knife, and on top of the three-foot blood blade, a blade actually extended forward, accompanied by Cheng Fei turning the blade, picking it in reverse, slashing the giant wolf's chest hard, and slashing at the other party's outstretched claws.

"Poof!"

A puddle of blood flew, a bloody broken claw fell to the ground, and the extremely powerful giant wolf was cut off one of his claws without even making two moves under Cheng Fei's hands.

Between Cheng Fei's backhand, the blade turned again, and the blood flashed, passing through the neck of the giant wolf, and in the midst of the blood flying, the giant wolf let out the last half of the wail, his body was weak, and he collapsed to the ground weakly, and the blood gushed out, staining the surrounding land red, obviously unable to live.

"This giant wolf doesn't look weak, presumably, its flesh and blood should be a great supplement!"

With a wave of his hand, Cheng Fei directly put the giant wolf's corpse into the mustard seed space, and his movements were extremely skillful, obviously, it was not the first time he had done such a thing.

The smell of blood spread, and in the surrounding jungle, there were faint roars of several giant beasts, and there was a deep dangerous aura, Cheng Fei's face changed, and he scolded secretly, and was about to turn around and leave,

Suddenly—

In the depths of the dense forest not far away, a gust of wind suddenly blew, and in an instant, the sand and rocks were flying, and the plants and trees on the ground were uprooted, and they were swept away by the strong wind and thrown into the air.

"Roar!"

Cheng Fei was taken aback, and before he could react, a terrifying beast roar had already rushed into the sky!

"Oh no, it's a mighty beast!"

If it was normal, he was not afraid, but he had just played a life-and-death chase with that dragon in the underground river, and his strength was exhausted, and he had not yet recovered.

Suddenly, his face changed drastically, Cheng Fei didn't think twice in his heart, he directly urged the qi in his body to the limit, and suddenly exerted force under his feet, his body jumped up, and rushed out into the distance like a gust of wind.

Fighting against such a powerful beast in a state of physical and mental exhaustion, Cheng Fei didn't want to take any risks, after all, once something went wrong, he would have to pay with his life.

"Click! click!"

The sound of trees breaking sounded one after another, just a few breaths, a huge black shadow from far and near, a cyan giant wolf with a body of two feet tall appeared in the place where Cheng Fei was originally located, almost no difference from the previous giant wolf, except for its super large size, the only difference was that its eyes still flashed with a trace of wisdom.

It's even turned on the psychic mind?!

Cheng Fei glanced back when he was running away, and when he saw the smart luster of wisdom flashing in the eyes of the cyan giant wolf, he couldn't help but be horrified in his heart.

The innate strength of giant beasts is already much stronger than that of human beings, and the reason why human beings can compete with giant beasts is because human beings have wisdom, and among giant beasts, there are very few people who can open their spiritual wisdom and have wisdom. Even many extremely powerful giant beasts are often just fierce beasts that only know how to hunt and eat, and it is because of this that humans can occupy the world and become the masters of the earth, while the giant beasts can only survive in the mountains and forests.

However, once the giant beast turns on its intelligence and has intelligence, the situation is very different, and the combination of strength and wisdom will have an incomparably terrifying strength!
