It was an indescribable pain.

It's like there are countless ants, frantically biting at the flesh. At this time, there is a very strange feeling, rippling.

This is also Yan Feng's familiarity with the method of retrograde vein-cutting, and he has practiced.

Otherwise.

Even if you are a human in two lives, you will faint in pain.

Once the syncope has passed, what will happen next is incalculable.

And so he is.

Not to mention the others.

'I didn't expect that the feeling of exchanging martial arts veins was so sour!'

'If my willpower is a little weaker, maybe I will fail, and if I fail, I'm afraid it's not just a waste of a thousand points, it's as simple as that!'

"However, such pain is impossible to scare me!"

'I'm Yanfeng!'

'I am a human being in two lives, and nothing can bother me!'

Time!

Yan Feng's eyes were full of bloodshots.

Let that golden light merge into the flesh, a little bit of tearing pain that fuses with one's own flesh and blood, wantonly impacting.

Yan Feng also looked calm.

At this moment, he has stabilized.

Such and such!

Little by little, time passed.

One minute!

Five minutes!

Ten minutes!

Half an hour passed, and the golden wave that blasted into the depths of the flesh and blood finally stabilized, and transformed into a vein with a golden streamer, which was on par with the martial veins he already possessed, running through his body.

This is the martial arts.

Yan Feng spent a thousand points to exchange for the martial arts.

As soon as this martial vein came out.

There is also an unusually comfortable feeling, rippling from the inside out.

Yan Feng couldn't help but let out a sigh of relief, and said with a smile: "My martial vein qualifications have finally been improved by one level, and they have become two!

He in his previous life.

There are only two martial arts.

He also relied on the qualifications of the two martial arts, and he rose all the way and created all kinds of miracles.

But that's also an innate limitation.

As a last resort.

Now it's different!

The system really redeemed a martial vein.

It really made his qualifications better.

Yan Feng's ambition also rose: "If you can exchange one, you can exchange it for the next time!"

"Even in the end, let me have nine martial veins, it will no longer be a problem!"

Come to think of it.

Yan Feng's spiritual sense fell on the window of exchanging martial arts.

Immediately after, the system prompted and popped up: 'If you want to exchange for the second martial vein, you need to consume ten times the points of the first martial vein, that is, 10,000 points [Note: The cultivation foundation is less than the double martial arts, and it cannot be exchanged]'

Yan Feng was stunned for a moment, but it didn't matter.

'I now have two martial veins, breaking through the double martial arts, the biggest obstacle has been cleared!'

'Breaking through the dual martial arts is no longer a problem!'

"The matter of exchanging the second martial vein, let's wait until the cultivation breakthrough is discussed!"

Important:

10,000 points.

He can't take it out now.

You must know that Yanfeng's system points are only six points left.

Also at this time.

Yan Feng exchanged these six points for an elixir that replenished the true yuan qi and ate it in one bite.

This breakthrough also consumed his true yuan.

The whole person can be described as exhausted and must be replenished in time.

The next moment!

The torrent of energy evolved from the furious elixir swept through the whole body.

Yan Feng's tired body was recovering at an alarming speed.

Less than half an hour.

Yan Feng, who was sitting on the ground, bounced up from the ground and let out a long breath: "Next, it's time for me to sweep away demons!"

Follow.

The breath of fierce martial arts qi and blood couldn't stop shooting out from Yan Feng's body.

He was already roaring out of the cave.

It's just that at the moment when he rushed out, a sharp whistling sound suddenly sounded above his head.

A voice came out.

There was an overwhelming cold breath that fell from the sky.

Yan Feng's eyes moved slightly, and the whole person suddenly accelerated, and in a moment, he had already rushed out four or five meters away. At the moment when he rushed out, a dark and heavy figure fell with a bang, landing right on where he had just stood. Rao is this place, very strong.

But he couldn't hold this guy swept out, and his claws were as sharp as scimitars.

Bang bang bang!

One stone after another, it was blown to pieces.

I saw that among the dark dust that was rising, one broke through majesticly, exuding the aura of a double upper step, and stretched out two demons that stretched no less than five or six meters, staring at Yan Feng with two eyes.

Yan Feng's expression moved slightly, and he also stared at this demon, and said, "What do you really want!"

"Since you're here, don't think about leaving!"

"Let's become the nourishment for my cultivation to break through!" Before the words fell, Yan Feng didn't give the other party a chance to act first, and had already jumped up from the ground. The person was in mid-air, and the terrifying sword light from the war knife was already one step ahead, rushing in front of the demon.

As if enraged, the demon hissed, raised its claws suddenly, and did not retreat or dodge, and slapped it fiercely towards the flying knife light.

Just as its claws were about to land on the sword.

The sword light, which was still extremely powerful just now, was like a collapsing stream of water, snorted, and dissipated without a trace.

Time!

The demon's attack missed, and the strong inertia pushed its body forward.

But it was also at this time.

Another powerful sword light swept out.

With a poof, it landed directly on the demon's head.

The demon who completely lost his defense was beheaded with a sword. The next moment, this guy's heavy body slammed into the ground and no longer moved, but he had been killed by Yan Feng. Immediately after, Yan Feng stepped forward and took advantage of the situation to take the blood crystal revealed by this guy into his pocket.

"Congratulations to the host, capture a double sixth-order demon blood crystal, if you exchange it, you can get sixty-three system points, do you want to exchange it?"

Yanfeng chooses no.

Wumai's qualifications have been improved.

Then the next thing Yan Feng has to do is to improve his cultivation.

For a month, it was very difficult to break through the double martial arts.

But stepping into the peak realm of the first level, Yan Feng is still very confident.

And blood crystals.

It's the most direct kind of energy.

In the presence of blood crystals.

Yan Feng prioritizes the use of blood crystals.

If there were no blood crystals, he would choose the elixir.

The general pill has lost the fierce and direct nature of the blood crystal, which is not conducive to Yan Feng's cultivation of the retrograde pulse cutting technique.

At this time.

Yan Feng didn't think about it, he had already eaten this blood crystal in one bite.

The next moment!

The fierce and powerful energy, like a scorching stream of fire, swept along Yan Feng's throat and swept through his body.

It won't take long to pass.

He was also pushed by the retrograde vein technique to open up the martial vein and increase the true yuan.

Time.

There was a strong tearing pain again.

But Yan Feng's face did not change, as if nothing had happened, and it was even more time at this time, the pace did not stop, continue to move forward!
