Yan Feng was stunned.

In the past half a month of rebirth, it was the first time I heard this voice, and I was really shocked.

At this moment, such a strong desire shook Yan Feng's mind, coupled with Yan Feng's cultivation, he urgently needed a blood crystal.

If you can become a martial artist one day earlier, you will be able to get the strength you want earlier.

For a moment, Yan Feng's thoughts rolled, and he cautiously glanced around.

Whether it was the ordinary people gathered with him, or the warriors who were fighting fiercely in all directions, no one noticed this. What's more, there are too many flesh and blood of black creatures spraying down from the sky. Such a piece of flesh wrapped in blood crystals is too popular to see anything special.

Suddenly, Yan Feng's mind settled, and he secretly said, "It's done!" and reached out without a trace, covering the black piece of flesh and blood.

In the next moment, the entire black flesh and blood, along with the blood crystals inside, disappeared.

And the voice in Yan Feng's head sounded again.

"Successfully captured a Blood Crystal!"

"Energy Analysis!"

"Demon Exchange System Activated!"

"Ding Ding Ding!" Immediately after, Yan Feng's head roared, and a large flickering wave suddenly exploded, only to feel that there was something more in his head.

Involuntarily condensed my thoughts and blasted into the depths of my mind.

The next moment, Yan Feng felt that he appeared in a space where spiritual light fluctuated.

This space is empty, full of spiritual breath, and it is like a huge screen in the shining sky, presenting his current state completely.

'Name, Yanfeng!'

'Cultivation, none!'

'Exercises, none!'

'Weapons, none!'

'Integrals, 5(?)'

'System?' Yan Feng is no stranger to this.

In this era, there may be no traces of modern civilization, but there are still demon eras. After all, before the age of demons, it was the era of modern civilization and prosperity. It's just that because of the advent of the demonic breath, modern civilization can't fight against it, coupled with the rise of martial arts, thousands of miles of sound transmission, fighting cattle across the mountains, and even flying away, burning rivers and boiling the sea, moving mountains and reclamation, and the power of supernatural explosions has emerged, and something in modern civilization has gradually disappeared.

Now it's more like returning to the ancient martial arts era and cultivating martial arts.

In the face of the powerful martial arts power, what else is it?

At this moment, Yan Feng's heart shook, and indescribable joy burst out: "In my head, there is actually an additional system! With the power of system coordination, the power of martial arts in this life can go more smoothly." ’

Follow.

Yan Feng's gaze fell on the question mark behind the integral marked 5.

Seeing the fluctuating information, they came one after another: "System points, taken from the blood crystals condensed by the demons themselves, or the energy containing the attributes of the demons! The blood crystals condensed by the first-order demons are worth at least one point, and the maximum can be ten points." ’

"The points obtained can be exchanged for the elixirs needed for cultivation, the original cultivation spiritual objects, and various resources needed for cultivation, and can also be used to improve the level of exercise weapons!"

Of course, it can also be directly exchanged for cultivation, but the ratio of exchange for cultivation is ten to one, that is, a blood crystal worth ten points condensed by a first-order top demon, and the cultivation exchanged can only make the host's cultivation barely go to the step of making cultivation from scratch. ’

"Now with five points, it is impossible to improve your cultivation and become a martial artist. Yan Feng was thorough and understood completely.

At the end of the day, this system encourages me to actively hunt demons and plunder blood crystals. The points I have obtained can be exchanged for various cultivation resources, but in order to maintain my motivation and not give birth to a lazy and depraved heart because of this, I am strictly restricted from directly using points to improve my cultivation. ’

It's better to directly exchange for pills and other resources, and it is more appropriate to cultivate by yourself. ’

For a while, the light in Yan Feng's eyes became more intense.

As an existence reborn as Emperor Wu, how could he not know this benefit?

Suddenly, Yan Feng's originally very stable state of mind became a little uncontrollable, "With this system, the path of cultivation in this life, there is no doubt that it will go more smoothly!"

"Maybe it won't be long before I can rise against the current and return to my previous life to cultivate, the forest demon, the rebels and thieves who betrayed me, and the evil villains in this life, all of them will die!"

Of course.

No matter how strong Yan Feng's mood change was, the surface was still very calm, and there was not the slightest fluctuation.

Even at this time, he didn't directly activate the exchange system and test the functions of the system, but cautiously withdrew from the system, sitting on the ground like no one, waiting for those warriors in the sky to repel those demon creatures.

But he didn't know.

On the other side, in the crowd gathered, there was a pair of eyes that flashed with strange waves, floating towards him as if they were nothing.

！

The battle at the scene, although tragic, did not last long.

A moment later, as Du Wei Chi Feng slashed the opponent and galloped to the aid of other warriors, a short time later, the demon creatures besieging in a manic manner were all killed. And the price paid by these warriors was only a few minor injuries.

Immediately after, there were warriors cleaning up the scene.

In fact, there is no need to clean up, these dark creatures were killed, and after the blood crystals were extracted, the corpse fragments directly turned into billowing black smoke and dissipated.

At this time, a martial artist with a deep breath, holding a plate full of red and strawberry-like blood crystals, walked up to Yu Chifeng, and said in a loud voice: "Lord Duwei, this battle exterminated twenty-five first-order demons, nine second-order demons, and three third-order demons, a total of thirty-six blood crystals. ”

Yu Chifeng's eyebrows raised slightly, and he said in a deep voice: "Why is there one missing?"

The warrior shook his head and said in a deep voice: "My subordinates don't know!" As he spoke, his gaze swept in all directions, falling on the ordinary people gathered in a group, and he whispered, "My subordinates suspect that someone has picked up a blood crystal and hidden it privately." ”

You must know that blood crystals are not idle things, but strategic reserve-level resources, and their control is very strict. It's not that ordinary people can't have blood crystals, but even if they get it by accident, unless they can refine it without a trace, they must hand it in. Of course, from official channels, buying it yourself does not count.

It is a felony to possess blood crystals.

It is possible to detain for three months, to mine for a year, or even to be beheaded.

At this moment, Wei Chifeng's expression was solemn, he nodded, pressed one hand on the combat knife at his waist, walked among the crowd, and said loudly: "Just now my soldiers told me that there should be thirty-seven blood crystals, but one is missing! In other words, one of you has hidden one privately. ”

As soon as these words came out, the audience shook.
