The clouds were thick and low, and they were so black that they seemed to cover the sky with a whole block of lead, and a huge dark red city towered over the black-brown earth.

Eternal and iron-blooded!

Towering and majestic, but also independent of the world, incomparable, as if it is the center of heaven and earth, the protagonist of the world.

Anyone, when they see the black shadow of that huge city, will be shocked and tremble, and they can't describe the feeling in their hearts.

Countless people, all the way through hardships and dangers, encountered countless beast training attacks, after many bloody battles, hovering between life and death, with their own strength, to fight a bloody road, to the center of the trial world.

When they saw the huge black shadow of the city like the ancient mountains in front of them, they were all stunned.

"Iron City ......"

"Is this the Iron City......

A low murmur sounded, and everyone lost their minds, even the gods of the temple.

Speaking of which, the general temple of the hundred clans is more magnificent than the city in front of him, but this city has a unique atmosphere, a unique atmosphere that has gone through countless vicissitudes of life and blood, iron-blooded city, iron-blooded battle.

Even if it is a saint-level powerhouse, in front of Iron Blood City, he will maintain a bit of humility and awe.

Iron Blood City is the masterpiece of the god of the hundred races, the center of the trial world, and the place where the true geniuses of the hundred races have clashed since the opening of the trial world countless times, and the black and brown land is sprinkled with blood.

Coming to the Iron Blood City, the geniuses of the hundred clans all have a feeling of pilgrimage, as if they are going to a holy land.

Here, sprinkled with the blood of the sages.

Under the awe, there are bursts of heroism and high spirits.

The geniuses of the Hundred Clans, from all directions, approached the Iron Blood City and entered the Iron Blood City.

One Man Iron Blood. The geniuses of the hundred clans immediately fought for the area within the Iron Blood City, occupied each other, and fought again and again in the Iron Blood City.

......

The sun rises and the moon sets, day and night alternate, and the torrential rain hits, and in a flash, seven days have passed.

A figure shot out of the dense forest and landed. When he saw the black shadow of the huge city in front of him, he was stunned.

If someone wants to kill Chu Duan, now is the best time to attack, but unfortunately, the others here will also be shocked by the momentum of Iron Blood City.

After a while, Chu Duan came to his senses and couldn't help but let out an exclamation.

In his opinion, Iron City. It was one of the most unique and impressive buildings he had ever seen.

Unbeatable!

"Iron City, I'm here. Secretly, full of firmness. Chu Duan took a step forward and strode towards Iron Blood City.

You can see the outline of Iron Blood City, but there is still a long way to go before you reach Iron Blood City. The closer you get, the more you can feel the coercion emanating from Iron Blood City, the huge coercion. Breath of Iron Blood.

The ground under his feet constantly exudes bursts of cold breath, bursts of cold fluctuations, which seem to be black and brown, but are actually the color formed by blood precipitation.

Born by the hands of the gods, Iron Blood City has an incomparably long history and indescribable uniqueness.

Iron Blood City, said to be a city, in fact, does not have a city wall, any place in all directions, you can enter the scope of Iron Blood City, and you can leave at will.

This is an undefended city.

Taking a deep breath, the cold breath poured into the body through the nasal cavity, poured into the lungs, and swept through the whole body, making Chu Duan feel excited and energetic.

Walking to the edge of the Iron Blood City, you can vaguely see the figures of people longing, and you can hear the voices of people.

The scope of Iron Blood City is extremely large, and it is divided into hundreds of regions, corresponding to hundreds of tribes.

The Terran has a human area, and the direction where it is located is exactly the direction of the Terran altar in the trial realm, if the Terran swordsman does not go around to other places, he will not enter the area of other races.

Entering the area of other races at will will end in a miserable situation.

In the Iron Blood City, there are no clear rules, you can do it at will, you can also kill people at will, as long as your strength is excellent, but among the same clan, if there is no big hatred, you will generally not do it, but if there is a contradiction, it is not necessarily, if it is hatred, you often see each other and blush, and you will take out the sword.

"Five-star Sword King?"

"The five-star sword king has actually come to Iron Blood City, and it looks like he is still alone. ”

Chu Duan's entry into the Terran area of Iron Blood City immediately caused the surprise of many Sword Kings.

"Either this guy has cultivated god-level exercises, or he is a body refining sword king, and his body refining attainments have reached at least seven stars. Someone said.

The four words of god-level exercises suddenly made countless people's eyes widen, flashing with an astonishing light, and then quickly disappeared, they understood how precious god-level exercises were, countless swordsmen, people who cultivated god-level exercises, but only a small part.

Although the god-level exercises are good, they mean that they cannot be provoked.

Even if Chu Duan's back did not have a huge amount of power, and the god-level exercises were only obtained because of his personal good luck, but in the case of so many people, any news would be leaked out of the country at the least, provoking the disaster of killing.

Of course, they were not very sure that Chu Duan's exercises were god-level exercises, and they were more inclined to the idea that Chu Duan was a body refining sword king, after all, when the body refining level reached the seven-star level, he could also enter the trial realm.

However, with only the strength of the Seven-Star Sword King level, it is impossible for a single person to go to Iron Blood City, and to be able to come here, the strength is extraordinary, and it cannot be underestimated.

Many people understand a truth, the swordsman who dares to walk alone, survives countless dangers, and survives and is intact, is often more terrifying.

"It's you, you dare to come to Iron Blood City. ”

Chu Duan walked forward, and suddenly, a roar full of anger came from far and near, and the last word seemed to sound in Chu Duan's ears, followed by an extremely powerful killing machine lock, the long sword was unsheathed, the sword broke through the air, and the incomparably cold sword light pierced through the sky and suddenly killed.

This sword, with the determination to kill, with an incomparable resentment towards Chu Duan, wants to kill Chu Duan and then quickly.

The moment the sword was released, the other sword kings around reacted quickly and retreated one after another, they didn't want to be affected, and at the same time looked at Chu Duan one by one, how to deal with this lone five-star sword king.

The sudden attack made Chu Duan terrified, a sword that would kill him, Chu Duan reacted quickly, his footsteps moved, and he cast an inch by inch, and an afterimage was crushed by the extremely powerful sword light, and the sword light trembled, and he slashed horizontally, wanting to cut off Chu Dui's head.

This sword is a sword that is extraordinarily exerted, and it is a sword that bursts out of its own strength by twelve points, and in an instant, it changes many times in a row, and the sword wants to kill you.

Chu Duan's body shape also changed many times in an instant, because of the battle with the wolf beast, the inch step also reached a new level, and it was displayed more smoothly and freely, avoiding every sword fatal attack.

The figure appeared in front of him, a pair of eyes full of hatred, staring at Chu Duan fiercely, if the gaze could kill, Chu Duan would have already been broken into pieces.

The five-phase sword came out of the sheath, and a sword cut through the transparent air, leaving a faint sword light, and the sword light was dazzling, making people can't help but squint their eyes.

Like a thunderbolt, like a storm.

In the vastness, the irresistible sword light slashed in front of him, causing the sword king who had to attack Chu Duan to be shocked, but it was too late to dodge, and the sound of fluttering sounded, and everyone only felt that their necks were cold, as if there was an invisible sword blade cutting through their necks.

Blood spurted out like a spring, and the skull was blasted into the air, tumbling in mid-air, falling to the ground, rolling a few times and stopping, eyes wide with hatred, horror and disbelief.

If you can't kill someone, you will be killed!

Killing the other party, Chu Duan didn't feel uncomfortable at all, and with a single pick of the tip of the sword, he directly picked up the opponent's spatial ring and put it away.

This person was just an eight-star sword king, but his identity made Chu Duan's brows frown slightly, because he recognized that this person was one of the previous disciples of the Black Sun Sword Sect.

This means that the other disciples of the Black Sun Sword Sect should have also come to Iron Blood City, they have a great hatred for themselves, and once they encounter it, it is likely to be an endless situation.

Chu Duan naturally has killing intent towards them, and if he has the opportunity, he will definitely not let the other party go.

But he also understands that the strength of the disciples of the Black Sun Sword Sect is not weak, and he is fearless one-on-one, but in the case of one-to-many, it would be good to be able to save his life.

Therefore, you must first improve your own strength, and only when your strength is improved can you solve the trouble.

In the Iron Blood City, you can do it at will, and Chu Duan can't refine the Dragon Elephant Fruit to improve his strength.

There must be a relatively safe environment, fortunately, when the Iron Blood City was built, the gods also took this problem into account, so in the area of each clan in the Iron Blood City, there are practice rooms, as long as you pay the corresponding price, you can enter the practice room to cultivate.

The practice room is where Chu Duan is going.

In addition to the practice room, there are also buildings built in the area of each clan, which are lined up one by one, and are places for the geniuses of each clan to live.

Chu Duan quickly went to the practice room, and the disciples of the Black Sun Sword Sect also knew that the person they hated had come to Iron Blood City, and also killed one of their senior brothers, one by one, they were furious, and they came out to find Chu Dui, wanting to kill Chu Dui as soon as possible.

Not long after, Chu Duan came to the practice room, the practice room was arranged in rows, orderly, and the dark red exuded a thick cold.

At this time, a group of disciples of the Black Sun Sword Sect also quickly caught up, and along the way, someone provided them with news and learned of Chu Duan's destination.

"Stand still. The voice full of anger came from behind, and the incomparably cold killing machine was extremely powerful, one by one, it locked Chu Dui from afar, approaching rapidly, and the sonorous sounds sounded one after another, and the disciples of the Black Sun Sword Sect all drew their swords......
