Castle of Black Iron

In the 5 change realm of shadow knight, Zhang Tie's body separation skill was also improved. Although his substitute couldn't fly as fast as his original body, it could also reach almost 10,000 m per second using the skill of divine dominator.

At this speed, it took Zhang Tie's substitute less than 20 minutes to reach over 6,000 miles higher and enter the high-altitude air zone of Motian Realm.

Very few immortal generals could enter such a high altitude. Even though airboats could not reach such a height. At this altitude, he could see many air-borne mountains in the sky below. By contrast, there was nothing else but chilly wind above him.

It was pitch-dark over there where only clear and bright moonlight and starlight could cast down dimly.

There was only one moon in Motian Realm, which was utterly different than that in Kun'ang Continent. After staying in Motian Realm so long, each time Zhang Tie watched the sun, the moon and the stars, he would have a strange idea——Were these things created together with Motian Realm?

Heller said Motian Realm was bizarre space and world being similar to Castle of Black Iron; additionally, it was a bit incomplete. If Motian Realm was created by someone who created Castle of Black Iron, Zhang Tie really wondered about the great power who created Motian Realm and the sun, the moon and the stars in it.

It explained why Zhang Tie always behaved modestly; because he knew that all the powers such as shadow knight, heavenly knight, semi-sage knight or sage-level knight were dwarfed in front of the power that created Motian Realm and Castle of Black Iron.

In the world he came from, sage-level knights didn't know how to make progress anymore. In this world, immortal emperors, above sage-level knights might reach high levels and new realms that the others couldn't touch.

Zhang Tie wondered about the realm of immortal emperors.

Across the Motian Realm, the top secrets included how sage-level knights promoted to immortal emperors. As the legendary nine heavens immortal spring was in Mountain Ruins, Zhang Tie finally found an opportunity to explore it after preparing for it a few days.

Mountain Ruins was vast. It was said that the core region of Mountain Ruins would open in a few years. It was necessary for Zhang Tie to take a look at the periphery of Mountain Ruins.

The top secret about Mountain Ruins was in its core region. However, in the periphery of Mountain Ruins, there were also numerous secrets and resources. The entire Mountain Ruins was the battlefield of heavenly knights across the Motian Realm. Over the past hundreds of millions of years, numerous powerhouses above heavenly knights kept exploring and fighting in Mountain Ruins endlessly, whether humans or demons.

Compared to the situation inside Mountain Ruins, although there were also contradictions and wars between immortal palaces in human domains, they were not as fierce as that in Mountain Ruins in most cases as they mainly plundered population and territory.

According to the information that Zhang Tie had learned, the entire Mountain Ruins was completely the battlefield of knights above heavenly knights in Motian Realm.

There was even a popular saying in Motian Realm that powerhouses who were not famous in Mountain Ruins were not qualified to found immortal human palaces or demon palaces.

Zhang Tie had to take a look at Mountain Ruins since so many demon powerhouses above heavenly knights were in there, not to mention those treasures over there.

As for Zhang Tie, those demon powerhouses were more like movable treasury than enemies. By reining their chakras, Zhang Tie could promote to real powers and return to Taixia Country as fast as possible.

What Mountain Ruins was to Zhang Tie was what fresh flowers to bees and what flame to moths.

As this substitute had already completed its most important performance and was useless in a short period of time. Therefore, Zhang Tie preferred to have his substitute take a look at Mountain Ruins for him before fading away itself.

The substitute used his flight ability as a divine dominator. Although it was not fighting, such a flight also cost his substitute a great amount of spiritual energy. As a result, it could not fly at such a high speed for too long.

As for Zhang Tie's substitute, it was a tough challenge for it to fly 200,000 miles using the flight ability as a divine dominator.

Zhang Tie's substitute flew overnight before arriving at the area below Mountain Ruins at daybreak.

It was not an easy trip from the area lower than Mountain Ruins to the periphery of Mountain Ruins as there was a special air zone in between called Ice and Fire Heavenly Strong Wind Layer (IFHSWL). According to the map, Zhang Tie knew that this layer was a barrier for some to enter Mountain Ruins from the air zone below it, which was perilous.

Before Zhang Tie's substitute touched the Ice and Fire Heavenly Strong Wind Layer, he had sensed the especially berserk wind element in this space.

Zhang Tie's substitute stopped there as he started to observe this barrier while his pupils revealed a beautiful lotus flower.

The Ice and Fire Heavenly Strong Wind Layer was really as worse as its name.

The over 600 miles thick void below the Ice and Fire Heavenly Strong Wind Layer was blue. Various shapes of icicles were coming into being and disappearing into the sky continuously; some of them were like fine sands; some were like rocks; some were like sharp sabers; some were like spears. Like meteors, these icicles faded away like heaving sand in strong wind in the blink of an eye.

Above this blue air zone, there was an over 600 miles thick faintly rouge air zone, where sparkles, flames or fire rain appeared out of the void and disappeared. Before disappearing, some flames would leave long fiery tails or fireworks which gradually faded away themselves.

Under painters' brushes, the ice and fire heavenly strong wind layer might carry a bizarre aesthetic; however, in Zhang Tie's eyes, what he saw meant dangers.

It was wind elements that filled the entire IFHSWL, which were flying across the sky like hurricanes at high speed.

The ice and fire in this layer were not pure water and fire; instead, they were the manifestation of the water element, fire element and wind element. They directly came from elements realm. Although they looked pure, they couldn't be caught and refined by knights in this state.

After observing it for a while below the IFHSWL, Zhang Tie's substitute immediately entered it.

The moment he entered the IFHSWL, Zhang Tie's protective battle qi had been completely isolated by those icicles. It was out of Zhang Tie's imagination that he lost his flight ability as a divine dominator for the first time in the layer.

The entire IFHSWL was filled with the heavenly wind which was composed of manifested berserk wind elements as dense as mercury which moved at a pretty high speed.

In this state, Zhang Tie's spiritual energy became water as it couldn't combine with the air zone dominated by wind elements at all. Of course, his substitute couldn't fly there. Not only that, even his protective battle qi felt like being broken apart by the heavenly wind.

Zhang Tie was startled. After losing his flight ability, Zhang Tie felt like jumping into a torrent as a person who couldn't swim.

In a split second, Zhang Tie had started to roll in the air zone like a piece of paper. In the blink of an eye, Zhang Tie had been blown away hundreds of miles and fell out of the IFHSWL.

The moment he left the IFHSWL, Zhang Tie had recovered his flight ability as a divine dominator.

Zhang Tie tried several times and got the same result...

In the end, due to the exhaustion of his spiritual energy, Zhang Tie's substitute directly faded away in the IFHSWL. Even his clothes turned into ashes.

...

In the mountain cave, Zhang Tie who had refined wind elements overnight opened his eyes at a stroke with a heavy frown.

"That's strange. Even heavenly knights could penetrate through it, why can't I make it? Given battle strength, I have long reached the level of heavenly knights..." Zhang Tie murmured. After thinking about it for quite a while, Zhang Tie who was lighting his wind chakra suddenly patted his head as his heart raced, saying, "Does it mean that only after lighting the entire wind chakra could I combine my chakra's energy and spiritual energy with the layer and fly in there? It must be like that! F*ck! What a barrier for knights..."

Since he promoted to a divine dominator, it was Zhang Tie's first time to encounter this situation——even heavenly knights could enter it; however, he couldn't make it.

This discovery directly over-ambitioned Zhang Tie.

Although Zhang Tie felt unwilling, he still accepted the fact rapidly.

This Ice and Fire Heavenly Strong Wind Layer warned Zhang Tie that although he was powerful as a divine dominator, he was not almighty. Sometimes, the realm couldn't be replaced. Additionally, "weak" was always relative.

Although a tiger was powerful enough to tear off a blue sheep, it couldn't jump flexibly like a blue sheep on cliffs.

After thinking through it, Zhang Tie soon adjusted his mentality as he continued to refine that wind chakra, eyes closed.

A few days later, Zhang Tie promoted to 6 change realm of shadow knight. After that, he put on the pair of metal wings and left the mountain cave for Dragon Emperor City leisurely.

During the past days, the news that Dragon Emperor was back and a new Dragon Emperor was appointed had spread over Motian Realm, arousing great responses...
