Castle of Black Iron

Heller’s smile was as familiar and warm as before. Whenever Zhang Tie promoted to a higher level in Castle of Black Iron and opened his eyes, he would be able to see Heller’s brilliant smile and listen to the familiar and genial greeting.

Perhaps it was the sweetest gift that Zhang Tie could receive after promoting to a higher level.

Feeling the perfect and powerful wind chakra, Zhang Tie slowly stood up from a boulder on the top of the mountain. Watching the snowy peaks of the verdant Immortal Mountain and the heavy mist around him, Zhang Tie felt complex.

‘I’m already a heavenly knight. It’s really difficult for me to reach this level.’

It only took him a few years from a shadow knight on the eve of the battle at Weishui River to a heavenly knight. Perhaps, it was impossible for others to promote to heavenly knights within such a short period of time; however, it was actually a long period for Zhang Tie as he had spent many years in the tower of time. During this period, Zhang Tie had experienced too many rises and falls such as departure of his family members, betrayal of his trusted clansman Zhang Taixuan, the hatred of Lan Yunxi whom he loved, the wrestle between him and the top three sects of Taixia Country, the founding of Jinwu Palace and falling into an alien world…

Despite being a few years, it felt being like half a century to Zhang Tie.

Some regrets could never be fixed…

Some tears should be dry forever…

Some people died…

Some people were still alive…

The perfect and brilliant chakra of a heavenly knight didn’t draw a period for his past; instead, it was a result of his efforts and struggles over these years.

If Zhang Tie promoted to a heavenly knight in Taixia Country, he would be pretty proud of it. However, the heavenly knight was just the beginning towards a real power in Motian Realm.

There were semi-sage level knights, sage-level knights and extremely powerful immortal emperors above heavenly knights. Being a heavenly knight was just a beginning for Zhang Tie to return to Taixia Country.

Zhang Tie’s complex mood in his eyes was gradually replaced by a strong will.

Although it was just a start, he was…a…heavenly knight…

Zhang Tie revealed a faint arc at his mouth corners. He casually pointed at the sky while a sonic boom sounded in the air right in front of him at the edge of the cliff; its strong air flow made Zhang Tie’s hair and clothes sway in the air.

The loud boom and the strong air flow originated from the changing state in the spatial territory. Only by pointing at it casually, Zhang Tie had made a huge vacuum space which was hundreds of meters in length, width and height while all the air in the vacuum space was withdrawn by Zhang Tie.

This presented Zhang Tie’s ability after lighting his wind chakra as a divine dominator.

Wind could take shape through air flow in space. However, wind, especially the attributes that wind elements could present was never just air flow.

With the control of Zhang Tie’s spiritual energy, a piece of cloud took shape on the top of the huge vacuum region. After that, rains drops started to fall into the vacuum territory from its top.

After falling into the vacuum territory, the raindrops turned into snow, ice, icicles, ice sabers, ice spears and ice swords. In the blink of an eye, hundreds of ice weapons had been manifested in the huge vacuum territory. Those weapons then started to shuttle back and forth and cut through the entire vacuum territory, turning it a large fatal battlefield at a stroke.

After running about half a minute, the entire fatal battlefield suddenly stopped. All the ice weapons were just staying still in the vacuum territory. In an instant, all the weapons broke apart and turned into crystal ice particles, which then gradually turned into ice gears.

With Zhang Tie’s control, the entire huge vacuum territory was like a piece of sponge which kept sucking more and more moisture, causing the temperature inside it to constantly drop. After that, the water gradually became ice gears, beads and machinery components which gradually started to assemble within the vacuum territory.

Gradually, a transparent difference engine being composed of ice components appeared in the vacuum territory, giving out dull blue light. After that, all the gears and levers of the ice difference engine started to run as the “metal curtain” being connected with the difference engine started to output patterns and calculate. The “metal curtain” gradually displayed five words through numerous rising and falling ice beads and rollers——I am a heavenly knight.

Heller was watching on one side in the whole process.

At this moment, if someone else was at present, he must be petrified by what he saw as he would treat it as magic. However, Heller knew that it was definitely not magic; instead, it displayed Zhang Tie’s great power after promoting to a heavenly knight as a divine dominator.

When Zhang Tie was a shadow knight, he could control water by turning moisture into water droplets or ice or snow or realize a free conversion between the three conditions of water. At that time, he could already control the temperature to a certain degree.

However, after lighting his wind chakra, Zhang Tie could not only turn water into ice, but also control the temperature between 0 degrees Celcius to -200 degree Celcius.

Just now, when moisture turned into ice gears, the core region of the vacuum territory had been -200 degrees Celcius while the gap between molecules was compressed to the extreme.

On this occasion, the ice cubes were not common; they were more like eternal ice cubes which were even harder than steel. Therefore, those gears and components could assemble a difference engine like how metal parts could do and make calculations and movements with Zhang Tie’s precise control.

It was simple and not mysterious for Zhang Tie at all. However, Heller knew that nobody else among humans could do it like Zhang Tie. Even Lord Fairysea couldn’t do it. Even though Lord Fairysea was a divine dominator with strong spiritual energy, he couldn’t visualize a set of difference engine being composed of numerous parts and gears like how Zhang Tie did in his mind sea.

At this moment, Zhang Tie’s ability to control ice and temperature alone had already surpassed the abilities of ice magicians or ice and snow queens in fantasy stories or novels…

Whereas, it was not the full abilities that Zhang Tie had acquired after promoting to a heavenly knight…

Under the gaze of Heller, the difference engine suddenly stopped running while everything in the vacuum territory turned into ice particles again. After that, a bizarre wave appeared on Zhang Tie’s side while the oxygen and hydrogen in the air were separated from air before being injected into the vacuum territory.

As Zhang Tie snapped his fingers, an area of strong flames appeared in the vacuum territory at once.

After the flames died out, everything in the vacuum space along with the vacuum space itself had disappeared. Everything recovered normal while some wisps of vapor rising up in front of Zhang Tie like nothing had happened before.

“How about that?” Zhang Tie turned around as he asked Heller.

“Amazing! It’s like magic. Besides Castle Lord, I’m afraid that nobody else in this world could have such a great ability…” Heller said sincerely.

Zhang Tie burst into laughter while a pair of 20-m longer colorful and brilliant cyan wings appeared behind Zhang Tie. As the pair of wings flapped themselves tenderly, Zhang Tie slowly left the ground. After flapping his wings forcefully, Zhang Tie instantly disappeared on the top of the Immortal Mountain…
