This mountain range stretches for I don't know how many miles. Xu Feng has been here for seven or eight days, and he has been advancing for more than 2,000 miles all the way.

This is a strange place. Legend has it that in the Hundred Years War 10,000 years ago, a demon emperor named Hades was killed by a powerful character and fell here.

This Demon Emperor's bloodline talent is to gather evil, and he has cultivated the "Black Evil True Decision", and his body is majestic and earth-shattering. When it fell, the evil qi soared into the sky and spread out, forming a huge sea of evil qi, enveloping this mountain range and infiltrating it.

This mountain range has been eroded and changed, and since then it has become a black place, and many fierce beasts in the mountain range have been affected by the evil qi, breaking the shackles of bloodline and evolving into demon beasts, and more demon beast races are hidden in it, and they regard this place as a treasure land for cultivation.

In the past, whether it was a demon beast or a human, they searched here many times for the bloodline inheritance of this generation of demon emperors, but they all returned empty-handed. After so many years of exploration and verification, it was finally proved that there was no bloodline inheritance, and only the mountains that had been eroded and mutated by the Demon Emperor's majestic evil qi remained. The only value is that in the body of the demon beast born here, there will be blood beads.

After the Blue Dragon Sect's advancement of the Endless Mountain Range again and again, this place has become a marginal area close to the human territory.

The only three demon beasts that stepped on the Void Realm were also cleaned up, and they became a place of trial for the younger generation.

When there is no trial value here, the Blue Dragon Sect will once again advance into the depths of the Endless Mountain Range. It will become a place for nearby urban development and exploration, and over time it will slowly change into a habitable territory for humans.

The entire Northern Regions was expanded by the guardian sects of each era in this way.

Xu Feng has figured out why no matter how many sects have been updated in the past 10,000 years, this place of trial has always had the only constant meaning. I have to admire the person who initially established his power in the Northern Regions, and he is really a generation of overlords with great talent.

Since killing the Xuanshan Bear, he has been running all the way, Xu Feng suddenly noticed the black evil qi wafting in the air, and suddenly it became more than a few chips, this black evil qi not only erodes the body, but also can arouse people's evil thoughts, miscellaneous thoughts, greedy thoughts, and desires. If it weren't for the fact that Xu Feng had a sea of swords in his mind to suppress his heart, he could ignore the black evil qi.

If it is an ordinary martial artist who just suppresses his mind, he has to use thirty percent of his strength, and it is very good that his own strength can still exert seven achievements.

This suddenly thick black evil aura showed that there must be a demon beast entrenched here. Xu Feng cautiously advanced for several miles, suddenly his eyes froze, and he felt a fierce and bloody breath rushing towards him, and a demon beast appeared in front of him, more than two meters long, with blood-red eyes and sharp and shining claws, like a black whirlwind, came to Xu Feng in front of him with a roar, opened his bloody mouth and bit it hard.

This demon beast, wrapped in black evil qi, has a healthy body like flowing water, and has a beautiful fur with golden threads, which turned out to be a golden leopard.

The golden leopard is gifted, its speed surpasses its own strength, it is a solitary demon beast, it has no fixed place, and likes to wander around.

"Boom!"

In an instant, Xu Feng made a move, his body did not move, and the power of the Flesh Void Realm was suddenly released, and a huge and astonishing momentum gushed out, accompanied by bursts of dragon chanting and elephant roars.

Stretching out his hand is the "Eighteen Palms of the Descending Dragon" with a palm, and the golden leopard screamed, and was knocked out by this majestic and fierce force, and the black evil qi around it instantly collapsed, and the body was stunned in mid-air, and suddenly exploded and fell apart.

In the midst of this flying flesh and blood, Xu Feng reached out and grabbed an egg-sized blood bead from the broken flesh, turned his hand over, and disappeared into the space in the identity plate.

In the palm of the "Eighteen Palms of Dragon Descending", Xu Feng only used the body of the Grandmaster Realm to play the power of the Shock in the air, and he actually reached the power of the eightfold of the Grandmaster Realm.

Xu Feng's face smiled slightly, in addition to the speed, this golden leopard's own strength did not exceed the seventh level of the Grandmaster Realm at most, Xu Feng was quite satisfied with the effect of using the "Eighteen Palms of Dragon Descending" to play a little bit of true meaning of comprehension.

Today, with the martial arts magic skills given by Xu Feng to the system, the number of uses, and the growth of proficiency, he is more and more able to comprehend the deeper mysteries of each martial art.

In the original world, it was difficult for Xu Feng to imagine that the martial arts in the book were not just the realm described, and every time he practiced more, he had a deeper experience. Perhaps in the original world, too many restrictions can not exert more power, whether it is the starting point, or the artistic conception, the truth expounded, is extremely profound.

The body moved slightly, posing for the posture of "Eighteen Palms of the Dragon Descending" internal refining, and the true gang of the whole body flowed, all over the body, not only the muscles and bones were strengthened, but even the five internal organs of the inner mansion had a trace of improvement, and in the long run, it could last for a long time to improve and strengthen, which was something that the exercises of the same level in this world could not do.

Xu Feng understands all this, the martial arts of the previous life, each of which has a unique artistic conception, can improve himself for a long time, not just learn it, that is the biggest loss to the use of martial arts.

Without these ten days of training and fighting, Xu Feng might not have discovered the mysteries in the martial arts for a long time.

"Whew!"

Xu Feng adjusted slightly, moved directly, and then advanced into the depths. Along the way, no matter what kind of strength of demon beasts they encountered, they all used martial arts to kill them one by one. Collect and compare the information about this Black Demon Mountain Range that you have seen in the Blue Dragon Sect.

The closer you get to the depths of the Black Evil Mountains, the heavier and stronger the Black Evil Qi becomes. The black aura in the air condensed into a gray mist, which slowly turned into pure black. All kinds of evil qi that induced depravity and madness continued to seep into Xu Feng's mind.

However, those black evil qi entered Xu Feng's mind, and it was like a sea of rivers that directly merged into the sea of swords, and disappeared directly.

"Huh!"

Xu Feng stopped, carefully observed the sword sea in his mind, watched this trace of black evil qi disappear into it, and finally found that this sword sea actually had a slight growth.

Now Xu Feng is finally sure, at the beginning, he felt that the sword sea suppressed his mind in his mind, and there was a little hazy sense of expansion, and he thought it was just a reaction when the sword sea was suppressed. Unexpectedly, this was not the case, and he absorbed the black evil qi here, smelted into a part of the Sword Sea, and increased the scope of the Sword Sea.

Xu Feng continued to move forward after understanding, but seven or eight miles away, he encountered a strange snake again, and stared at Xu Feng with its head raised high.

In the eyes of the demon beasts here, Xu Feng is like a lighthouse in the dark night, the flesh and blood are like rainbows, the flesh condensed by "dragon elephant like a miracle", the most rigid and yang is like a round of small sun, a trace of dragon blood, a trace of brute elephant blood, and countless demon beasts, eager to evolve their own bloodline, absolutely has an incomparable attraction.
