In this shadowy area, there was no life, and a few small purple grasses that grew tenaciously around it quickly withered and dried up at a speed visible to the naked eye, and finally turned into powder and were blown away by the wind, leaving no trace;

Xu Feng only felt as if he had entered an ice cellar, if it weren't for the warmth coming from his neck, Xu Feng felt that he was probably about to be frozen by this cold;

There was no sign of frost, just a dead chill welling up in my heart;

"Is this what hell is it like?" Xu Feng thought in his heart;

Gritting his teeth and insisting, a trace of Yin red flowed out from the corner of his mouth, and a series of injuries emerged from the top of Xu Feng's head, and after a while, a quarter of his blood volume had disappeared;

Xu Feng struggled, took out a bottle of continuous healing and recovery medicine from the package and poured it down, and gradually felt a trace of warmth on his body; Looking up, a huge black dragon swept overhead.

The body of this black dragon is as long as a hundred zhang, the whole body is black and purple, the double horns on the head are shining, as if the black crystal is crystal clear, the scales on the body are layered, with a purple-black luster, the dragon tail is more than ten meters long, the tip is like a mace, the bone spurs are uneven, in flight, the dragon tail is flicked and flicked, but the invisible air flow emitted by the unconscious will smash the rocks more than ten meters large in the desert, as if the roar of the missile washing the ground, in Xu Feng's ears continue to sound;

"This, the strength of this black dragon has definitely surpassed the Nine Stars!" Xu Feng gritted his teeth and thought, at this time, Xu Feng didn't dare to make any movements that might attract the attention of the black dragon, and he didn't even dare to release the insight technique, so he could only look up and observe the black dragon's departure with his naked eyes, and the direction in which it left seemed to be the upper reaches of the Noel River;

"There seems to be something on the back of the black dragon?" Xu Feng looked at the black dragon, opened his mouth wide in surprise, his eyes showed a terrifying expression, and he roared wildly in his heart;

Following Xu Feng's gaze, on the black dragon's broad back, a long sword with a flickering cold light was firmly inserted into its back, revealing only one-third of the blade and handle;

In front of the black dragon's huge body, the long sword was as insignificant as a toothpick, but it was this insignificant wound that was constantly gushing purple and black blood, and the blood continued to flow along the black dragon's huge body, dripping in the jungle.

The blood of the black dragon, like a scorching flame, and like sulfuric acid, dripped on the rocks of the desert, emitting a wisp of white smoke, making a corrosive sound of "snorting", and even some huge black stones, ignited by the blood of the black dragon, and burned with a bang, and the whole desert seemed to have turned into hell all at once, burning with raging flames.

"Whose weapon is that, who can inflict such harm on this black dragon? Could it be an immortal? Xu Feng stared at the long sword that was constantly shining in the sunlight and said in a low voice.

At this time, Xu Feng had already confirmed that the direction of the black dragon was the upper reaches of the Noel River, and perhaps its target was the source of the Noel River. Every once in a while, the black dragon will let out a roar, the roar of the black dragon, all with the power of the dragon, after each roar, there will be a crackling and falling collision sound in the desert, and then, there is the sound of many desert creatures running and fleeing.

Xu Feng didn't know that there were so many unknown creatures hidden in this desert; He found that every roar of the black dragon would make people feel a wave of fear from the bottom of their hearts, but after seeing the long sword on its back, Xu Feng could actually feel that in this terrifying roar, there was always an indelible pain and sorrow in it.

Watching the figure of the black dragon gradually disappear, Xu Feng took a deep breath, the long sword on the back of the black dragon made Xu Feng firm in a certain guess, Xu Feng continued to walk forward, his direction, like the black dragon, is the location of the upper reaches of the Noer River;

In the vast desert, Xu Feng believed that although it seemed lifeless, there must be a lot of fierce creatures hidden in this desert, and the harsher the terrain, the more fierce the hidden creatures, but under the dragon power of the black dragon, Xu Feng did not find a monster in the desert to attack him;

One day, the sun gradually wested, the surroundings became darker, the Nuoer River did not bring a trace of coolness to Xu Feng, but the temperature around him gradually rose unconsciously, and Xu Feng's face also appeared a trace of fatigue;

"It's getting late, and I need to find a safe place to rest." Xu Feng wiped the sweat from his forehead and said in his heart.

The remnants of the black dragon gradually dissipated, and the roar of a fierce beast sounded again in the desert at night.

Xu Feng once heard a legend that the real dragon creatures will have a premonition of their own death, and before they die, the dragon will go to a special place, which is called the dragon tomb, which is the final resting place of the dragon clan;

Xu Feng's speed is very fast, in this ancient world, Xu Feng did not dare to use the Tiger Wing Wind Thunder Wing, because on this pair of wings, there is a faint breath of the Wind Thunder Beast, and the powerful creatures will feel it, they will be attracted by this breath, and once they use it for a long time, they will be attacked by powerful beasts;

The desert area seemed to have passed, and the plants in front of Xu Feng's eyes gradually increased;

Passing through a small patch of dark red bushes, Xu Feng suddenly stopped his steps, raised his right hand, and the flying sword was in his hand, and a sword qi was like a sharp arrow, and it stabbed forward as if flying.

Puff~

Dead branches flew and rubble splattered in all directions, sword qi entered the revolution, and a bloody light shot out from behind a huge rock. Although it is a little tired, the powerful perception still plays a role;

Xu Feng stepped forward, a gray lizard's corpse, lying horizontally behind the rock, the scales on the lizard's skin were exactly the same color as the rock, it sensed Xu Feng's arrival, and was hiding behind the rock to prepare for a sneak attack, but it didn't want Xu Feng to kill it first;

"It's just a monster with five-star strength, and it doesn't even have a crystal nucleus." Xu Feng muttered to himself in a low voice, let go of the flying sword, the flying sword turned into a silver light, burrowed into his body, and Xu Feng walked forward without looking back.

In front of him is a jungle, Xu Feng walked through the jungle, and suddenly opened up in front of him, and what came into his eyes was a waterhole with a radius of ten acres, the waterhole was bottomless, the surface was slightly steaming, and a faint smell of sulfur came to his nose.

Seeing the pool, Xu Fenglin's spirit was shocked, he didn't expect that there would be a natural hot spring here, and after a day of travel, he could take a bath in this natural hot spring pool to relieve fatigue.

Just as Xu Feng was about to undress and enter the waterhole to rinse off, there was a "whoosh", and a black shadow rushed towards him.
