Follow.

Yan Feng's figure rose and fell, and he had already rushed out from his hiding place.

In addition, above the sky, it is pitch black, and it is the sky shrouded in the sky, dark and dim, not to the extent that you can not see the five fingers, but it is also a few meters apart, vague, if it is five or six meters away, unless the eyesight is excellent, otherwise there is nothing else to see except black.

And this time.

There was also a stronger cool aura, frantically impacting the skin of the flesh, wanting to kill into the depths of flesh and blood.

This is the demonic spirit!

It is also the energy that gives birth to demons.

Ordinary creatures, if they are contaminated with the slightest, can transform demons with an irreversible trend.

This is also the fundamental reason why ordinary people dare not step out of the city built by humans and go out after dark.

Because you can't resist the demonic spirit!

After conversion.

He became a demon.

Demon.

Even though he still retains his original body, he can no longer be called a human.

Of course, that's for others.

Such a demonic aura can't hurt Yan Feng. Even if he didn't condense the true essence of martial arts and promote martial arts, it would be the same.

At this moment, Yan Feng, with the excitement on his face, did not hide it, and muttered to himself: "I have been waiting for this day for more than half a month!"

"Now it's finally possible!"

“！”

At this time, Yan Feng boosted the battle knife in his hand and was about to go deeper. It's just that at the moment when the footsteps moved, his expression changed slightly, and he didn't want to turn around, and the whole person turned in place like a spinning top, almost avoiding a chilling breath sprayed from behind!

Syllable!

This empty breath fell heavily on the ground, and it collapsed into a piece of ground.

Meanwhile!

There was another piercing hissing sound, and it exploded suddenly.

The next moment!

A black shadow rushed out from the darkness several meters away. As soon as the black shadow came out, a deep aura like a substance swept out. At this moment, the scene is full of murderous aura, like a black wind flame that is churning upward, slamming out, still rushing towards Yan Feng!

Yan Feng's expression moved slightly, and he secretly mused: "At least a demon of the upper rank, the strength of the other party may be slightly inferior to Yuan Jiashan, but it is also above ordinary martial artists!'

Yan Feng didn't think about it, he pushed the knife in his palm, as if he had eyes on the back of his head, and stabbed him behind him regardless of it!

This knife!

It's fast, it's fast, it's clean, and it's never muddy.

The shock wave that suddenly evolved was extremely violent. The most important thing is that the speed of flying out is faster than the black shadow rushing over. If you don't give the black shadow a chance, you will already take the first step and kill the past.

Time.

The fierce sword light blew away the heavy dark aura, and in this way, this demon hidden in the weight of the shadows was forced out of its original form.

This is a black wolf with a long black mane and a strong body.

This guy seemed to be taken aback by Yan Feng's sudden killing blade, and his two scarlet eyes trembled fiercely. But this guy is also very good, in a moment, there was a sudden brake in mid-air, strong limbs, muscles bursting, blasting out this brute force, almost avoiding the rushing knife light.

Just don't wait for it to breathe a sigh of relief!

Yan Feng, who had missed the sword, had already rushed in front of it with a smile on his face.

The demon black wolf was furious, roaring with his head high, and the fierce roar resounded through the mountains and forests in all directions. Immediately after that, this guy opened his big mouth and bit towards Yan Feng again.

Merely.

It's too slow.

Yuan Jiashan, who was completely held by Yan Feng, died at his hands, not to mention such a demon, which is not as good as Yuan Jiashan's demon?

I saw a puddle of black blood gushing out!

The demon black wolf's body was separated, and it was already slashed by Yan Feng, just like killing Yuan Jiashan.

The next moment!

This guy slammed his body into the ground.

Yan Feng took another step to follow, and the battle knife came out.

Poof!

The demon black wolf had been disemboweled, and a red blood crystal was presented in front of Yan Feng like this.

"Blood Crystal!"

Yan Feng laughed, where was there still half a minute of hesitation, rushed up in one step, and held this blood crystal in his hand.

The corpse of a demon without a blood crystal.

Slightly wavering.

It has been like weathered dust, and the wind swept away without a trace.

Meanwhile.

The voice of the demon exchange system, which had been silent for a while, sounded: "Congratulations to the host, you have captured a complete blood crystal!" After system analysis, the quality of this blood crystal has reached the eighth order, if you exchange it, you can get eight system points, may I ask, do you want to exchange it?"

The cultivation of demons is the same as that of warriors.

Each weight is subdivided into nine and a half steps.

Yan Feng also saw it.

A demon, cultivated to a higher level, the system points exchanged, there is one more point, as for the last half level, and because it is cultivated to the extreme realm, the points exchanged, as before, can get a little point.

At this moment.

Hear the sound of the system.

Yan Feng hesitated slightly, and soon, he made a decision: "For me in the current state, cultivation strength is the most important thing! With higher cultivation and stronger strength, you can kill stronger demons! And strong demons, their points are obviously higher!"

"Then now, I won't exchange it first, use these primordial blood crystals, and improve my cultivation first, which is the most important thing!"

"When, when will I be promoted to the peak realm of the first lower level, or the captured blood crystals will not be enough to cause a big change in my cultivation, let's exchange it again!"

At this time.

Yan Feng ignored the prompts of the system, and stuffed this blood crystal into his mouth without thinking.

Time!

The torrent of violent energy was directly transformed into the purest qi and blood energy, and with a bang, it exploded in Yan Feng's body. This kind of energy, crazy and disorderly, just in an instant, Yan Feng's body was impacted into a mess. At this moment, inside the body, there were dense popping sounds.

This is the sound of flesh and blood not being able to hold up the energy, and exploding.

Suddenly.

The indescribable pain, shaped like thousands of knives, and the crazy barrel pierced every corner of Yan Feng's body.

But even the pain is extraordinary.

Yan Feng didn't seem to feel anything, just his facial muscles subconsciously trembled, and his complexion and expression, as always, did not fluctuate.

If it were someone else, I am afraid that I would have been tortured by such energy and collapsed on the spot, not to mention driving the exercises to control such energy.

But Yan Feng didn't.

He was born with strong willpower, and he is a human being in two lives, and more importantly, he often did the same thing in his previous life, once he was born and twice matured, he has long been used to it, and more importantly, he also has a 'retrograde pulse cutting technique'!

The retrograde cutting recipe is born for this!
