But in the process, Ye Feng's face became even paler, and finally he had to give up the attack, retract the blood-colored bone knife and flying sword and calmly retreat, and the two horns also flew back to the bison's head again.

Then, Ye Feng stood aside panting, and the bison looked a little sluggish at the moment, but its eyes were full of anger, especially the pain in its body made it even more angry. After all, its realm was too low, and its spiritual intelligence was not too high, so it chose to attack when it should have dodged.

"Roar!"

The bison roared, rushed over with its head down, and its four hooves made a rumbling sound when it came into contact with the earth, like an earthquake, and the speed was much faster than before, rushing towards Ye Feng.

Ye Feng remained silent, pretending to be invincible, and fled quickly, and the direction of progress was the hard rocks around him.

A wind-like figure in front of him fled quickly, and a huge cyan figure behind him chased closely, and the momentum seemed to be unreachable, vowing not to give up, vowing to trample the figure in front of him into flesh.

At this time, Ye Feng was getting closer and closer to the mountain rock, and he was about to hit the mountain rock.

"It's at this moment!" Ye Feng's eyes burst into essence, and a silver light flashed all over his body, disappearing in an instant, and at the same time, the figure of the bison disappeared.

"Boom!"

The next moment, Ye Feng's body appeared in the position before the bison, but the bison hit his head on the mountain rock at the moment, and the two horns of the ox were lost and could not be pulled out, and the bison seemed to be stunned at this moment, and his eyes widened.

"Take advantage of your illness to kill you!" Ye Feng's eyes burst into light, and without the slightest hesitation, he quickly rushed to the bison, the golden light flashed on the back of his right hand, and the flying sword roared out, piercing the armor-like skin with a pop, piercing the bison's heart.

At the same time, Ye Feng held the bone knife in both hands, and with a pop broke through the protection of the skull and pierced the bison's brain.

The bison stared wide-eyed, shook its head and body violently a few times, and then stopped breathing, and did not bat at its eyes.

"Whew. ”

Ye Feng wiped the flying sword and bone knife, then carefully put it away, and immediately sat down to the side and gasped.

"I didn't expect it to be so troublesome to kill a cow, and I didn't expect this demon beast to be so difficult, worthy of being a wise guy. But speaking of which, this bison has no grievances with me, and I lost my life like this, isn't it a bit too inhumane......" Ye Feng thought in his heart while absorbing the aura of heaven and earth to recover his strength.

Immediately, Ye Feng shook his head with a wry smile: "This is the cruelty of cultivating immortals, there is no right or wrong at all, and there is no distinction between justice and evil, everything is for strength, and in the world of cultivating immortals, strength determines everything......"

Calming down, Ye Feng stopped thinking about these trivial matters, closed his eyes and absorbed the aura while summarizing the gains and losses of this battle. This is a habit that Ye Feng has developed in the past few months, and he must seriously summarize it after every battle.

Soon, the time of a candle incense passed, Ye Feng was in good spirits, stood up and stretched, and slowly walked towards the bison standing dead.

"It's time to learn the secrets of the monsters. ”

Although the cyan bison is dead, it still exudes a faint demonic aura all over its body, which is strange and terrifying, even if it is just a corpse, it makes people dare not approach easily.

Its skin is dull, but still steely, giving it a cold and cold feel.

The thick limbs were densely covered with green hair, the four hooves like sea bowls were sinked into the earth, the sharp horns on the head pierced deeply into the rocks, and the big eyes like copper bells froze the last anger, unwillingness, and a trace of fear, which was the fear at the moment of death.

"Alas, the Immortal Cultivation Realm is so cruel. Demon beasts never need a reason to kill monks, if I have to find an excuse, then I can only say that demon beasts are for the sake of maintaining their own territory or for food. Ye Feng sighed lightly, and the blood-colored bone knife in his right hand appeared, cutting off the huge head of the bison along his neck.

Under the demonic aura, the blood did not coagulate, and the crimson blood gushed out, and a faint smell of blood filled Ye Feng's nostrils.

This made Ye Feng stunned for a moment, and then his eyes lit up, and he immediately took out the old kettle that he had scavenged from Master Duobao's secret room, and let the gushing blood flow into the kettle.

However, when the kettle came into contact with the blood, a strange scene appeared: a strong suction force suddenly appeared in the kettle, and then it was not controlled by Ye Feng, and the whole thing hung in the air at the neck of the bison. At the same time, the bison's body and head gradually shrank, and blood fell into the kettle.

After only a few breaths, the huge bison suddenly became a dried corpse, and even the demonic energy that naturally emanated was gone, and it was all absorbed by the kettle.

After this process was over, Ye Feng retrieved the kettle, glanced inward, and found that there was only a drop of bright red blood in the entire kettle, exuding a thick demonic aura, as if this drop of blood condensed all the demonic qi and flesh essence of this demon beast.

"It's such a rich demonic aura, such a huge amount of energy, if there are dozens of such blood droplets, combined with my body quenching liquid, wouldn't I be able to impact the seventh layer of the body quenching realm in a very short period of time?" Ye Feng's eyes burst out, and then he carefully closed the lid and carefully wrapped it around with a cloth a few times, and then solemnly put it into the space ring.

Looking at the rest of the bull head again, Ye Feng touched his chin, he felt that this bull head was unusual, there seemed to be a suppressed demonic aura, which was very special.

Staring at it for a while, Ye Feng put away the bone knife, and the flying sword in his right hand flew away, cutting the dry cow's head layer by layer under the control of his mind.

The flying sword was extremely sharp, making a sound of cutting debris, and after a while, only a small piece of the huge bull's head remained, and this was the source of the faint demonic aura, the demonic aura loomed, as if it was suppressed by some inexplicable power, and could not be naturally emanated.

At this time, Ye Feng's speed was also significantly slower, be careful and careful, for fear of accidentally missing something.

Gradually, when this piece was only the size of a thumb, all the dried flesh and blood automatically fell off, and a crystal clear spar appeared in Ye Feng's hand, and there was a faint demonic aura on it.

"Demon Crystal, this is actually a Demon Crystal!"

Ye Feng's heart moved violently, his eyes lit up, and he suddenly remembered what his grandfather had told him about demon beasts before.

Every demon beast has a demon crystal in its body, and the function of this demon crystal is to absorb and refine the surrounding heaven and earth aura, and transform it into demon qi for their own use. Therefore, the demon beast's body always exudes an aura that is completely different from the surrounding aura.

The demon crystal contains pure energy, and the amount of energy is closely related to the strength of the demon beast.

Soon after each demon beast is born, it will condense its own demon crystal, and as it grows and becomes more and more powerful, the energy contained in the demon crystal will become more and more powerful, maintaining almost the same energy as all the demon qi in the body.
