Castle of Black Iron

Over 1,000 demon powers’ battle qi intertwined into a three-dimensional huge net in the air. Although the huge net looked very terrifying, it was full of loopholes in Zhang Tie’s eyes.

As ordinary demon generals couldn’t discover Zhang Tie when he was invisible, their strikes were always scattered. Therefore, Zhang Tie could always avoid their attacks easily.

Being invisible, Zhang Tie moved as fast as a lightning bolt. When he activated his flight ability as a divine dominator, he became a flying fish which could travel across torrents and sprays. Traveling among the gaps between battle qi strikes, Zhang Tie was seeking opportunities for launching strikes.

When over 1,000 demon powers gathered together, they were indeed very powerful; however, it was just relative. They would not be powerful any longer once they scattered. As for Zhang Tie, besides sage-level demon knights, most of the demon individuals among them were weak, even full-armored semi-sage demon knights.

Blind strikes would consume a large amount of battle qi. Zhang Tie believed that these demon generals couldn’t stand launching blind strikes for too long when they couldn’t discover him. When these demon generals couldn’t stand it anymore or became disordered in attacking rhythm or weaker in battle forces, it would be the best moment for Zhang Tie to hunt them.

There were many heavenly demon knights among them with complete fire chakras. Even though one heavenly demon knight wouldn’t do much help to Zhang Tie, as long as Zhang Tie could refine some more fire chakras of heavenly demon knights, he would also promote to a semi-sage level knight. He had already refined the fire chakras of five heavenly demon knights. Only after refining 10 more fire chakras of heavenly demon knights, he would be able to promote to a semi-sage level knight…

At this moment, Zhang Tie was pretty hyper. His mind was full of fire chakras. However, he didn’t find that he was already different than before. In his eyes, it was reasonable for him to kill some heavenly knights. It was nothing strange. However, if someone who understood Zhang Tie in Taixia Country were at present and saw him killing heavenly demon knights casually, they would definitely be shocked by Zhang Tie’s great change over these years. Zhang Tie had been unimaginably powerful.

At the bank of Weishui River, Zhang Tie killed a heavenly demon knight by hitting it for 9 times with a rod, in which battle, he aroused the attention of the others in the world. Now, Zhang Tie could kill those heavenly demon knights like killing chickens and dogs and refine their fire charkas only by punches instead of using any weapons. Those heavenly demon knights could only gather together for survival. Due to great change, Zhang Tie had already been on a higher level unconsciously.

However, those enemies that Zhang Tie encountered these years were too powerful. In Taixia Country, Zhang Tie’s enemies were sage-level knights at most; however, in Motian Realm, his most powerful enemies became demon emperors. All of these enemies were at the top of the food chain in the world. In front of these powers, due to great gap between levels, Zhang Tie always felt overwhelming stress. He even always felt tired escaping at the risk of his life. Therefore, Zhang Tie didn’t feel that he was too powerful.

However, in the eyes of the others, even those demon generals who were gathering together, Zhang Tie was already able to frighten most of them.

In Motian Realm, Zhang Tie was not the most powerful one; however, nobody else could casually overwhelm powers on the same level or even higher level except Zhang Tie. Facing Zhang Tie, those demon generals felt like facing an invincible rival instead of an immortal general of the same level. Zhang Tie’s overwhelming battle force could scare wind demon generals to death.

Being invisible, Zhang Tie was flashing in the meshes of the huge net being intertwined by demons’ battle qi strikes flexibly. Like a wild wolf circling around its prey, Zhang Tie was seeking opportunities to approach those wind immortal generals. Not until the small golden tower rushed to his front was he astounded…

The small tower started to rotate around Zhang Tie the moment it approached him. Before Zhang Tie realized what had happened, he had seen the Six-armed Demon Emperor rushing towards him with his palm strike and grim eyes.

Invisible Shen bead and master-level hiding skill could enable Zhang Tie to be invisible and hide his qi; however, it didn’t mean that he could deceive the eyes of wind immortal generals or sage-level knights. Demon emperors and immortal emperors had powerful spiritual perceptions. They could notice any single micro speck of dust in the air within hundreds of meters. Therefore, if Six-armed Demon Emperor approached Zhang Tie, it could definitely sense his existence.

Six-armed Demon Emperor definitely wanted to kill Zhang Tie by this palm strike.

Due to its greed for the small tower and hatred about Zhang Tie, Six-armed Demon Emperor had already exerted its full efforts to attack Zhang Tie the moment it sensed his location.

Zhang Tie sensed the powerful strength of universal law and the fierce intent of Six-armed Demon Emperor again. Last time, it was his substitute who sensed such a great power; now it was his own turn.

This palm strike was at least 2 times more powerful than that suffered by Zhang Tie’s substitute.

From hundreds of meters away, when Six-armed Demon Emperor released this palm strike, it twisted the fragile space immediately as an irresistible great force passed to Zhang Tie through the twisted space faster than any form of strike, causing Zhang Tie to show up at once.

It was the greatest adventure in the eyes of demon emperors and immortal emperors. Even though he was fine one second ago, he might be in a dilemma the next second once the super unrivaled powers shifted their target and strikes onto him.

Zhang Tie was in such a situation.

Nobody could predict that the small tower could suddenly fly towards Zhang Tie, not even Force Emperor. Additionally, Force Emperor couldn’t do it even if he wanted to save Zhang Tie at this moment; because Versatile Demon Emperor had already found that Force Emperor wanted to save Zhang Tie when Six-armed Demon Emperor was launching a strike at Zhang Tie. As a light flashed across Versatile Demon Emperor’s eyes, it instantly seized the opportunity. In an instant, the space within thousands of meters shrunk and turned black. Almost at the same time, Versatile Demon Emperor drew Force Emperor into its own realm.

Facing an immortal emperor on the same level, even though Versatile Demon Emperor drew Force Emperor into its own realm, it still couldn’t take any advantage of Force Emperor. Similarly, it was also impossible for Force Emperor to break through Versatile Demon Emperor’s realm in a short period of time. Only by trapping Force Emperor for a few minutes would Versatile Demon Emperor meet its purpose.

The one who was closest to Zhang Tie and was most qualified to save him was Star Emperor.

However, watching the small tower fly off his hand toward Zhang Tie, Star Emperor squinted his eyes at a stroke as he tightly pulped his mouth and revealed a faintly cold look.

At this moment, a presumption occurred to Star Emperor——did Zhang Tie make some tricks on the small tower when he touched it just now?

‘A wind immortal general dares scramble for an item with me. You’re seeking death. On this occasion, if your master Dragon Emperor was still alive, he would be qualified to scramble for it with me. If you died, Dragon Emperor Immortal Palace would lose its owner again..’

Many whims occurred to Star Emperor. He soon made a decision. Star Emperor didn’t save Zhang Tie; instead, he just heavily inflicted two supreme-level demon generals in front of him and broke the encirclement of the battle formation of those supreme-level demon generals before rushing towards Six-armed Demon Emperor and the small tower.

Facing Six-armed Demon Emperor’s fatal strike and sensing the strong power which enabled the space to undulate, Zhang Tie knew that he couldn’t resist it. At this moment, a whim occurred to him——enter Castle of Black Iron.

It was a method that Zhang Tie only used to protect himself at the critical moment.

Pitifully, Zhang Tie still underestimated the ability of the unrivaled power. When he ran his spiritual energy and intended to enter Castle of Black Iron, he found that his body was bound by wisps of an odd space force, which was as shapeless as a cobweb. When Six-armed Demon Emperor launched a strike, its odd space force bound Zhang Tie tightly and fixed him in this space. As a result, Zhang Tie couldn’t move freely; additionally, being drawn by this force, he couldn’t leave this space at all.

That got to be Six-armed Demon Emperor’s means. If it wanted to kill someone, its target could only wait for death.

Zhang Tie roared as he retreated as fast as he could. Meanwhile, he took out his golden secret item Heavens-Separation Sword and slashed towards Six-armed Demon Emperor at a stroke.

The light and sword qi of Heavens-Separation Sword surged out of Zhang Tie’s hand like discharging flood and collided with Six-armed Demon Emperor.

In a split second, the sword qi flood was torn apart by Six-armed Demon Emperor’s iron palm; meanwhile, it weakened the momentum of the battle qi strike of Six-armed Demon Emperor. When the remaining battle qi approached him, it was instantly blocked by Zhang Tie’s Heavens-Separation Sword. As a golden secret item, Heavens-Separation Sword was even firmer than a shield which was a silver secret item.

When Zhang Tie was ready to suffer this strike, he suddenly felt his battle qi becoming restless in his qi sea. Closely after that, all of his battle qi poured into the small tower which was rotating around him at a high speed. Only in an instant, a semi-transparent cover like that covering Zhong Ziqi just now had appeared around Zhang Tie’s body…

The fatal strike of Six-armed Demon Emperor directly hit the semi-transparent protective cover.

Due to a great shock from the protective cover, Zhang Tie spurted out blood at once. Closely after that, he flew towards the huge black tower as fast as a meteor…

Watching Zhang Tie flying towards the huge black tower, Six-armed Demon Emperor changed its face greatly as it instantly chased after Zhang Tie towards the huge black tower.

At this moment, Zhang Tie was actually not severely injured; however, he was still greatly shocked; because it was the small tower that drew him towards the huge black tower with the inertia of Six-Arm Demon Emperor’s strike.

At the same time, Zhang Tie’s battle qi was constantly absorbed by the small tower out of his control. Being driven by Zhang Tie’s battle qi, the small tower carried Zhang Tie towards the huge black tower like an ignited rocket engine by the semi-transparent protective cover even faster than a divine dominator.

Of course, in others’ eyes, even in the eyes of Six-armed Demon Emperor, Zhang Tie intended to fly towards the huge black tower by this opportunity on purpose…

When he flew towards the huge black tower, Zhang Tie suddenly became flurried as he felt being abducted by the small tower.

‘Damn it, this father is a living powerful heavenly knight. How could I be abducted by a static object…’

However, before Zhang Tie complained about it, he saw a huge gate at the bottom of the huge black tower, which revealed a space with rolling black fog. Almost at the same time, the small tower rushed inside the gate with Zhang Tie, blocking the last strike of Six-armed Demon Emperor out of the tower…

When Six-armed Demon Emperor rushed to the front of the huge black portal, it changed its face again and stopped outside the gate at once. It became hesitant instead of following Zhang Tie in. However, right then, a black fog surged out of the open gate and turned into a huge black hand before drawing Six-armed Demon Emperor into the huge black tower.

“Ah, no…”

The black gate disappeared, leaving Six-Arm Demon Emperor’s wail reverberating around the Mountain Plain.

All the powerhouses stopped fighting, including Star Emperor. Versatile Demon Emperor’s realm was broken. However, Force Emperor and Versatile Demon Emperor both stopped. All of them turned around and fixated onto the huge black tower.

Force Emperor and Star Emperor looked incredible. It was just a few seconds after the small tower flew towards Zhang Tie. The two immortal emperors couldn’t figure out what had happened either…

Watching the huge black tower, Versatile Demon Emperor suddenly trembled all over as its face turned dreadfully pale like that of a dead person. Versatile Demon Emperor had roared towards all the other demon generals who were in a daze and turned around and flashed away.

Force Emperor’s 1 m-longer machete had already chopped a supreme-level spider demon general into pieces before those demon generals responded to what had happened…

“Hahaha, son of b*tches, go die…” Force Emperor burst out laughing as he slashed towards another supreme-level spider demon general over 20,000 m away, shiny saber light breaking the space…

Over 1,000 demon generals broke up in an uproar and escaped in all directions.

When the army of immortal human generals within Mountain Ruins arrived here, there was no demon in the core of Mountains Plain anymore, except that huge black tower standing in the forbidding huge pit while giving out a strange light. Star Emperor was hacking the huge black tower by long sword time after time with numerous rays of starlights…

However, no matter how hard he tried, he still couldn’t move the huge tower a bit; he couldn’t even leave any trace on the huge tower; instead, the huge pit was expanded by two more times. The ground around the tower had disappeared, leaving the huge tower floating in the air statically alone…

Not until his long sword broke into pieces did Star Emperor let out a deep sigh. After turning around and taking a look at those immortal human generals, he flashed away and disappeared in an instant…

Today, the news that the Infinite Immortal Prison which was said to have existed in far-ancient times showed up in Mountains Plain of Mountain Ruins shocked all the humans and demons across Motian Realm.

Later on, too many human powers came to Mountains Plain to look at Infinite Immortal Prison with reverence. However, they could not do any harm to it no matter what means they used. By contrast, all the demons stayed far away from this place.

One month later, a group of 10-odd powers with different features came to the foot of Infinite Immortal Prison, including 7-8 supreme-level immortal generals. Bian Heng was one of them.

“Ziqi committed suicide here. He didn’t give the small tower to demons until death…” A supreme-level immortal general in violet gold crown sighed with grief as he took a look at that huge black tower.

“Ziqi was straightforward and frank in his whole life. He died in a righteous way just like that he used to be…” Another person sighed.

“If we’ve long known that this Infinite Immortal Prison was going to be another core of Mountain Ruins, our discovery of this Infinite Immortal Prison would become meaningless…” an old man beside Bian Heng said with a bitter look as he shook his head,”The core of Mountain Ruins might open in the future; however, I’m afraid that nobody could open this Infinite Immortal Prison in the future. As a result, it could only become a far-ancient relics…”

“It’s said that Infinite Immortal Prison contains the deity’s secret book Infinite King Roc Sutra . Even though we’ve already known the result, we still don’t want to give up this opportunity, right?” a woman with a young look yet in grey hair spoke as she glared at Bian Heng,”It’s said that you cured Zhang Tie…”

Bian Heng replied with a bitter smile, “I swear to God, I’ve not told him about the location of Infinite Immortal Prison. I even appointed with you to meet him in 10 months so that we could determine whether he was qualified to know this secret. After all, even though we could enter the tower, we have to pass the magic square battle formation. As Zhang Tie is good at math, I wanted him to give us a favor…”

“It’s indeed none of Zhang Tie’s business. Before Zhang Tie came here, demons had already discovered the Infinite Immortal Prison and started to scramble for it. Zhang Tie just passed here by accident at that time…”

“We’ve studied the small tower for so many years in vain. How could Zhang Tie and Six-armed Demon Emperor be sucked inside by this huge tower?”

“As we’re not far-ancient deities, how do we know all the secrets about the deity’s relics? Otherwise, we would be deities. I’m afraid that Zhang Tie and Six-armed Demon Emperor probably have died inside it…’

“Let’s go. Now that we couldn’t get this Infinite Immortal Prison, we need to think about finding something else in the core of Mountain Ruins…”

After circling around the huge tower for a short while, they all sighed and left there, leaving their Miss, grief and despair.

Coincidentally, when they left Mountains Plain, they met a wind immortal general in colorful clothes. He was Immortal in Clouds.

Over these years, too many human powers came to Mountains Plain. When they found that the opponents were not demons, they just passed by each other silently.

Only after a short while, Immortal in Clouds had come to the location Infinite Immortal Prison. After circling around it for a short while, he even approached the huge black tower. Then he took out of a small hammer from his portable space-teleportation item and knocked at it for a while. When he found that he couldn’t get anything valuable from this huge black tower, he squeezed out some turbid tears reluctantly and put away his small hammer. Stroking the black tower, he sighed with emotion. “Li, if you went with me, how could you lose your life in the Infinite Immortal Prison? These days, I’ve got a new trick to trap and kill ox-headed demon generals. If you’re still alive, we will definitely have numerous element crystals in the future. Pitifully, we cannot be partners anymore…”
