In the dark and endless black iron forest, a black shadow kept moving and jumping on the towering trees. It's so fast, it's terrifying.

The whistling sound kept ringing in his ears, Nie Fei hurried away, the purpose of going was the center of the Black Iron Forest, he was originally here to experience this time, but he didn't plan to go to the center of the Black Iron Forest in the plan, but the news provided by Yan Cong had to make him change his original plan.

He came out this time in the hope of finding the essence of life and improving his strength, and after listening to Yan Cong's news, he strengthened his belief even more.

It turned out that Yan Cong told him that there was a spring inside this Black Iron Forest, and what flowed out of that spring was not water, but contained a powerful and vibrant life essence.

Before Yan Cong finished speaking, he was shocked and made up his mind to take a look, no matter how difficult and dangerous it was, and there were many dangers.

The danger is indeed not small, I heard that in this spring, there is a powerful ancestral demon sealed, called "Immortal Yan Ancestral Demon" cultivation is powerful, even if it is a five-turn lone demon under him, he does not dare to raise his head, and this is because the ancestral demon has been sealed for nearly a thousand years, and the spring water of those life essences is to suppress him, and several powerful people have carried it from elsewhere.

From Yan Cong's depiction, Nie Fei felt from his heart that this ancestral demon was strong, and perhaps he had reached the seventh turn of the Venerable Demon, a Venerable who had cultivated to a high level.

Such a big person, he Nie Fei has never seen it, he has traveled south and north all these years, and he has only heard of it, even his aunt, Yan Wushuang, the palace master of the Flame Demon Palace, is just the peak of the Four Turns of Silence.

This is also an important reason for Nie Fei to want to enter the depths of the Black Iron Forest, although the risk is high, but it is a blessing in disguise, only the most dangerous places can get the greatest opportunity, he wants to give it a try.

Just as Nie Fei was running wildly, suddenly there was a commotion in front of him, and Nie Fei hurriedly stopped and crouched on the trunk of the tree.

"Quack, where did this ignorant person come from, a Xuan Demon dared to come here, so bold, kill him......"

A demon with a hideous and ugly face, covered with dark scales, and nails more than a foot long, looking at Nie Fei was like seeing a tender and delicious delicacy, and he almost drooled.

The others should be the subordinates he recruited, and they are also ugly, the kind that makes people sick to their stomachs when they see it, under the guidance of this fighting demon, the head demon rushed towards Nie Fei with hungry eyes.

"The little demon in the Soul Demon Realm also wants to eat me? ”

Nie Fei smiled coldly, his body flicked suddenly, and then the figure disappeared on the original tree trunk, and then appeared in front of the demon who surrounded him from all sides, punching, without using exercises, directly relying on brute force, fiercely piercing the demon's body. Fists entered from the front chest and appeared from the back, and a mist of blood exploded in the air.

"Squeak ......"

The demon's ugly face became more distorted, and he shouted in pain, but before the sound could be heard, Nie Fei punched again, directly landing on the demon's head, and the entire huge head exploded directly, shattering into pieces, and the demon's vitality was completely lost.

After two punches, Nie Fei did not stop, the figure moved again, and once again came to the demon attacking from another direction, with five fingers into claws, directly inserted into the opponent's skull, and a ball of soul was caught, and the body instantly turned into a walking corpse, paralyzed on the ground.

Without stopping, Nie Fei kept changing his body, but in the blink of an eye, the five-headed demon surrounding him was the only one left, and the big eyes of the copper bell almost fell out.

"You, you're not ......"

The demon showed extreme fear in his heart and wanted to escape, but how could Nie Fei allow him to escape, the Demon Refining Heart Sutra worked, and his body moved his five fingers and already grabbed the other party's head, "Tell me, is there a fountain of life here?"

"Big ...... My lord, I ...... I don't...... I don't know. The demon fell to his knees and trembled with fright, and could not speak.

"Hmph, it seems that you don't cry if you don't see the coffin, since you don't know, let's die!"

The five fingers pierced the opponent's head in an instant, and the demon shouted in fright: "My lord, spare my life, I remember." ”

"Say, otherwise I won't have a chance to reincarnate your face. ”

Nie Fei's face was cold, and his voice said ruthlessly.

The demon trembled with fright, his face turned pale, and he trembled, "Yes...... There is such a fountain of life, but ...... However...... "The demon looked a little embarrassed.

"What can you say?" Nie Fei tightened his fingers, causing the demon's eyes to turn white in fright.

"However, I've only heard about it, so I don't know if it's true. ”

"Hmph! It's like saying it in vain, what's the use of leaving you a waste. Nie Fei's face turned cold, and with a hard grasp of his five fingers, a ball of demon souls was refined by him, "Even if you know, how can I let you go, the demon is the most ruthless, don't you let the tiger return to the mountain?"

Killing a few demons in the blink of an eye was nothing to him, but it also sent him a message that he was about to enter the danger zone, so he must be more careful.

Now it's just that a demon with a low cultivation has appeared, and the more he goes to the center, the more the demon's strength snorts, and if he is accidentally plotted, he will probably have to explain it here.

After stopping for a while, refining these five souls, although there was no substantial improvement for himself, he did feel that because of this long time of traveling, his tired body and strength had all been improved.

Leaping suddenly, he disappeared into the woods again.

Although I have always heard that the Black Iron Forest has absorbed the power of people, what makes Nie Fei strange is that he didn't feel it, and he wondered in his heart, maybe it was the special feature of this Demon Refining Heart Sutra!

"Whew......"

Nie Fei made a move, the Demon Refining Heart Sutra operated, and the powerful flame cage directly trapped a three-turn demon and began to refine frantically.

It didn't take long for a three-turn Absolute Demon Great Demon Leader to be refined into nothingness by Nie Feisheng, and at this time, after absorbing the soul of this three-turn Demon Absolute Demon Realm, he felt that his strength had increased slightly, just like a strand of hair.

It seems that if you want to step into the second turn soul demon, you still need a lot of life essence, since you provoke me, don't blame me for being unkind.

Nie Fei looked at the numerous, innumerable army of devils, sneered in his heart, and pounced directly.

It just so happens that his Demon Refining Heart Sutra has an innate restraint against demons, and his strength will not decrease by a single point in this Black Iron Forest. Therefore, there is no fear of rushing into the army.

Snort~~

"Whew......"

Cutting the demon, and the demon's cry of pain was thought of, Nie Fei was like a hungry wolf rushing into the flock, the spear in his hand quickly reaping the life of the demon, while constantly absorbing their life essence.

Red light everywhere, falling leaves all over the sky, ruins and broken trees, everywhere in a mess, Nie Fei reaped the life of the demon regardless of it, absorbing and refining the soul, and soon felt that his strength not only did not feel tired because of the fight, but became more excited.

"Haha! Refreshing, I didn't expect you to send me benefits like this, I don't want to take so many demons outside!

Nie Fei became more and more crazy, the speed of the fight became faster and faster, he did not show any fatigue, and his strength became stronger and stronger, and this long period of actual combat combat gave him a deeper level of understanding of the Demon Refining Heart Sutra. It's also becoming more and more proficient in utilizing.

"Boom!"

Just when Nie Fei was in the middle of killing, there was a sudden rumbling sound in the distance, and then, I saw a huge demon eight feet tall, covered in bronz, vigorously pulling up a towering tree with his bare hands, waving the big tree and smashing it towards him, not caring about the lives of those little demons.

"Well, finally a decent one has come. Lynch shouted, his body suddenly ejected, not dodging, but fiercely greeting it, the flying dragon sword in his hand emitted a blazing red light, and the long sword qi turned into countless sword shadows and slashed towards the tree.

"Crackling!!"

In an instant, the towering tree turned into a rain of trees and fell, and the bronze demon only had a one-meter singing trunk left in his hand.

"Ahhh

The bronze demon, seeing the big tree in his hand, stomped his feet angrily and questioned Nie Fei.

"Boy, what kind of sword is the sword in your hand? ”

The bronze archdemon threw away the stick in his hand fiercely, and his big foot suddenly stepped towards Nie Fei.

"Why do you want to tell you! If you want to know what kind of sword it is, go to hell and ask Hades to go!"

Nie Fei jumped onto a big tree, trampled on the other party, and when his feet were just contaminated with the trunk of the Dao tree, he borrowed his strength out of thin air, and the atmosphere was suddenly mentioned, and the long sword in his hand drew a red arc again, and a move "Splitting the Star and Cutting the Moon" fell from the sky and landed on the body of the bronze demon.

"Boy, once you turn to the realm of the Xuan Demon, you dare to fight with the existence of the peak of my three transformations of the Great Demon, and it is worthy of glory to die. ”

This bronze demon turned out to be a powerful demon among demons, born with a huge force, and when he became an adult, he could shake the mountains with his bare hands, move the stars, and his power was infinite, obviously this head was still a juvenile strong demon.

Looking at the arrogant Hercules, Nie Fei smiled coldly and sneered: "I really don't know how thick the sky is, and I won't even know if you die when the time comes." ”

The Red Sky Sword Qi descended from the sky, but the Mighty Demon didn't care about wanting to use his strong body defense and strength to break this sword qi, and blasted towards Nie Fei's sword with a punch with the power of shocking the Five Desolations.

"Boom!!"

When the two collided, there was an earth-shattering sound, and the entire Demon Iron Forest trembled, and the two forces collided together, and suddenly burst into blazing sparks, and the defense of this powerful demon was really tough enough.

This sword qi cut into his body, leaving only a white mark, and Nie Fei was also shocked when he saw it.

Although this sword did not pour out its full strength, it was also fifty percent of its strength, and I didn't expect it to have the slightest effect on the bronze demon.

The death penalty is easy to avoid and the living crime is inevitable, but the mighty bear still let out a bitter cry.
