In the sense, it was a huge spot of light.

The dense energy aura of light spots is powerful and concentrated, far from being able to compare with the "black fog crystal" I just sensed.

Wow~!

Lin Feng's body teleported, and suddenly—

The eyes suddenly became clear.

It was a small valley, with huge vortex spiraling up, which was extremely similar to the vortex on the right in the stalactite cave. The strong black fog was rising, and in the huge dark curtain, tens of thousands of "black fog crystals" were quietly suspended.

"Silk~~" Lin Feng took a breath of cold air, his eyes shining brightly.

"My God, this is..." Lin Feng looked at one of the black fog crystals, pure black, without any impurities, and looked like a crystal that was extremely dark. It seemed ordinary, but the energy aura contained in it surprised the domineering thief of his heart.

A noun suddenly popped up in my mind—

Black fog crystal stone heart!

"Black fog crystal heart-grade crystal, also known as the 'Ten Thousand Years Black Mist Crystal'. It is formed by the quenching of the black fog crystal after more than ten thousand years of time. It condenses volume and essence energy, which are extremely precious." Lin Feng thought of the description of the black fog crystal heart in "Ore Diagram", and his heart beats wildly.

The black fog crystal stone heart is quite pure!

"If I absorb the energy of the 'Black Mist Crystal Heart', even if the efficiency is not as good as the inner alchemy, it will not be too different." Lin Feng's eyes suddenly brightened.

The most important thing is that there are quite a lot of "black fog crystal stone hearts" in front of you!

One tenth of it!

"Haha, it's not time to get it." Lin Feng smiled, and the purple ring in his hand flashed. Suddenly, it was like a thief coming. Whether it was the "Black Mist Crystal" or the "Black Mist Crystal Heart", Lin Feng took all of them, leaving no one left.

It’s also a blessing that the “Jing Zi Ring” is a three-star spiritual treasure, which has enough energy, otherwise it wouldn’t be able to hold it.

"This time I'm right here." Lin Feng smiled with satisfaction.

Originally, the biggest purpose of entering the depths of the Black Mist Demon Dragon Valley was to "avoid" the pursuit of the Black Mist Demon Dragon Army, but now-

But it was an unexpected gain!

"Very good." Lin Feng's eyes were bright. Chapter 8 The domineering thief.

I have gained such a harvest in less than half an hour, which shows that the "wealth" here is obviously far more than that. In other places, there will inevitably be more "black fog crystals", "black fog crystal hearts", and even...

"It may not be possible to gain other benefits." Lin Feng smiled indifferently.

The purple ring in my hand shines brightly, and the small valley will be swept away in a short time.

Only the dark fog was left, but there was no longer the existence of the "black fog crystal" and it was empty.

Looking at his "masterpiece", Lin Feng suddenly smiled.

The eyes flashed and disappeared in an instant.

A thief entered the Demon Dragon's nest.

A pretty 'noble' thief, because... he steals everything.

But at present, almost all the black fog demon dragons are going out to perform missions and chase Lin Feng.

The nest became empty instead.

"Hey, it's another Black Mist Crystal Valley." Lin Feng smiled alone.

In the heart and eyes, this is already the third "Black Mist Crystal Valley" I found. In every valley with vortex, in addition to the Black Mist Crystal, there must be—

The existence of the ‘Black Mist Crystal Heart’.

"The more you have, the better." Lin Feng was about to step in.

Suddenly, my eyes lit up. In this sensation, in addition to the strong energy aura, there was actually...

Breath of life!

"Oh, is it the Black Mist Demon Dragon?" Lin Feng's mouth slashed slightly.

With the body hidden, Lin Feng stepped in step by step. Although the fog was too thick and could not be seen, the sense of the mind and eyes would not be wrong.

"It should be a fourth-level black fog demon dragon." Lin Feng was calm.

For myself, hunting the fourth-level black fog demon dragon is effortless.

but……

"No need." Lin Feng shook his head.

Instead of risking the exposure of his identity and hunting a fourth-level black fog demon dragon, it is better to "pick up" the black fog crystal stones in full.

At least, when the black fog crystal is still so "enriched", there is no need to cause more trouble.

"It seems that the Black Mist Demon Dragon has no defense here." Lin Feng's eyes were bright.

Compared with the groups of black fog demon dragons outside, the black fog demon dragons here obviously lack the "crisis awareness".

No precautions for yourself.

Lin Feng didn't know that the reason why the Black Mist Demon Dragon here is so "calm" is because the leader of the Black Mist Demon Dragon clan lives here-

Tooth refining.

The super existence of the third realm of transformation!

I wandered around and casually "picked" the outside for half an hour.

When I came back, the fourth-level black fog demon dragon was gone, and a calm smile appeared on the corner of Lin Feng's mouth.

It was like a thief, finally waiting for his master to leave.

"Swoosh!" Lin Feng rushed in.

Sure enough, just as the heart-wielding eyes sensed, the vortex in front of him was like a shadow, and a huge black fog flashed. Accompanied by tens of thousands of "black fog crystals" and thousands of "black fog crystals" to form an amazing energy aura.

"I'm welcome." Lin Feng smiled.

The purple ring flashed, and the light shone brightly in a flash.

Lin Feng felt extremely satisfied as the "black fog crystal stones" fell into his pocket.

Time passes by minute by minute.

In the blink of an eye, most of the huge dark curtain disappeared, and Lin Feng smiled and accepted the "Black Mist Crystal Stone" again.

Anyway...whether it works or not, I'll take it first.

Accumulate small amounts into many things, just like practicing.

Sudden--

"Hmm?" Lin Feng's expression changed.

As the heart and eyes sensed, the familiar breath of life appeared again, and it was approaching quickly.

It's still the fourth-level black mist demon dragon!

"He's back?" Lin Feng's brows were slightly clumped, and he tsked lightly, and then he moved slightly to the side. It was like a thief was halfway through his work and happened to bump into his master and come back.

The fourth-level black fog demon dragon arrived in the blink of an eye.

As his body landed, the Black Mist Dragon lay next to the vortex and squinted his eyes.

It was the enjoyment that I was bathing in the thick black fog that suddenly the black fog demon dragon opened his eyes and his face changed continuously.

glance right and left!

In an instant, roared in anger!

"Oh no, I was discovered." Lin Feng frowned.

But it is no wonder that it is difficult for me to steal most of my property from its "home" and not be discovered.

The roar continued, filled with extreme anger, and Lin Feng frowned instantly.

If the black fog dragon screams, it will not take long for the rest of the black fog dragon to discover that with the wisdom of the black fog dragon, they will inevitably expose their identity and targets, and then things will gradually become bigger.

"Since that's the case, then you're in trouble." Lin Feng's eyes instantly became bright, and a hint of murderous intent appeared.

Kill the dragon and silence it!

A dazzling golden light suddenly appeared!

In an instant, a violent aura spread, and Lin Feng's figure appeared like lightning. The black aura of the "Dragon Killing Gun" in his hand condensed a slight red light, carrying a violent "black mist" surging, like a meteor hitting, and the five-clawed golden dragon rose up.

"Golden Dragon Qi!" Lin Feng's murderous aura was full of virginity!

The black fog demon dragon's face suddenly changed drastically, and an extreme pressure suppressed it, and his body trembled inexplicably.

That is the breath of a truly top dragon clan!

It does not have the strength of "transformation" like refining.

As a black mist demon dragon with only level 4 adulthood, in the clan, it is only the middle and lower level of the pyramid...

"Roar~~" the sound was a little weak, and the black mist condensed outside the body was completely suppressed by Lin Feng.

At this time, Lin Feng's attack came!
