Castle of Black Iron

Under the control of Zhang Tie, the trickling water elements filled into the patterns like how liquefied steel was poured into delicate molds from steelmaking furnaces. Pieces of molds were assembled like gears of a difference engine or the steel structure of a skyscraper. They started to have reiki and utterly different abilities. They would not be icy, useless or simple anymore. This was how Zhang Tie formed his water chakra.

When the last extremely sophisticated, mysterious, geometric pattern, which was shaped like a diamond, was fully filled by water elements under the control of Zhang Tie, Zhang Tie quivered all over at once while a familiar strength reappeared in his body. Being penetrated and affected by this strength, Zhang Tie’s body as a whole started to update automatically while each cell was becoming stronger and more energetic. The battle qi in the void of his qi sea surged once again like a rising tide. There were some more spiritual stars in the space of his mind sea. Those sparkling stars adorned the brilliance of the two full moons in his mind sea, making them more brilliant and denser. The light poured down like mercury…

After a long while, when this energy wave recovered its composure, Zhang Tie, who had promoted to the 9 change realm of earth knight and was only one step away from shadow knight, opened his eyes.

Zhang Tie then threw a glance at the empty water-element crystal in his hand before throwing it into Castle of Black Iron. After that, he got off the bed.

It was a strange room featured by the rich style of steel and steam. The room was made of the steel frame as all the beams, columns, basic partitions and floors were made of steel. Only the walls were made of pinewood. Given the look of the pinewoods, they had been used for a long time. After taking anti-corrosive treatment, the pinewoods gave out a bright yellow luster in the baptism of years. Such a luster brought the room some warm tint more or less. A row of 10 cm-thick steam pipelines penetrated through the walls like pronunciation tubes of the organ in the church. The exposed part of steam pipelines was connected to a row of crude yet durable heating units. As it was already March, of course, those heating units were not open yet. In winter, if the heating units were not available, it would be hard to tide over.

The room was not large at least for Zhang Tie. The entire room, covering less than 150 square meters, was divided into a bedroom, guest room, parlor, study, toilet and workshop. It was a high-level serviced apartment, especially for singles. Zhang Tie had been here for over 1 month. Everything in the room was practical and ordinary. Only the study and the workshop made people feel it a bit unusual.

The study included many professional books such as Metal Processing Manual ,Preliminary Learning on Alloy , Middle-level Learning on Alloy , Advanced Learning on Alloy ,  Science of Steam Dynamics , Self-cultivation of Runed Instruments Master , Dictionary on the Parameters of Crystal Energy and Mechanical Association,  A Summary on the Steam City-Defense System of Class A Cities ;  The XXth Issue of Steam World Magazine and Yearbook of Theses of Runed Instruments Masters Labor Union Headquarters on the 904th Year of Black Iron Calendar . Additionally, there were over 1,000 metal samples, a set of mini advanced alloy smelting crucible, a set of multi-functional steam processing lathe, a complex, comprehensive metal processing table and a set of input ports that could be available for acquiring computing power of the difference engine in the hotel at any time.

This workshop almost occupied half of this apartment. Given the arrangement in the study and workshop of this apartment, anyone could easily get a conclusion——this was an apartment, especially for rune instrument masters.

That was truly an apartment for rune instrument master.

Rune instrument master was also a senior human profession. The low quantity and supreme position of this kind of professional led to the very rare quantity of serviced apartments especially for rune instrument masters in many continents and subcontinents; unless the boss’s head was kicked by ass. Nobody would like to spend so much on preparing for such a room for such few customers. Starting from advancing to golden hammer artisan, a rune instrument master would not lack money wherever he was because there would always be advanced talents scrambled for by major clans and local forces. Such professionals would always have their own workshops; instead of doing studies in hotels.

Only Heavenly Craftsmanship City in Military Province of Taixia Country could provide serviced apartments and rooms especially for rune instrument masters in Eastern Continent and Western Continent.

The influence of Heavenly Craftsmanship City among people in Taixia Country could be seen from a familiar common saying——Battle fortresses in Taixia Country rank first in the world; Battle fortresses in Military Province rank first in Taixia Country; Battle fortresses in Heavenly Craftsmanship City ranked first in Military Province.

Heavenly Craftsmanship City was a unique Class A city with a rich feature of this age. As for steam engineers and rune instruments masters, Heavenly Craftsmanship City was their holy land.

The entrance from where humans entered the Earth-element Realm was in Military Province. The special geographical location and the history of Military Province in the former two holy wars led to Heavenly Craftsmanship City.

Zhang Tie left Kangzhou City directly for Heavenly Craftsmanship City about 2 months ago.

Strictly, Zhang Tie’s trace was indeed confidential. Because Zhang Tie was here for developing a weapon that could be used to kill demon knights and completely grabbing the highest-level force of demons away from the air to the ground by the power of steel and steam in the hand of humans.

Zhang Tie wanted Taixia cities and commoners to get hang of the power for resisting even killing demon knights. That was absolutely a crazy whim.

Zhang Tie rarely had any ambition, except for this one. By then, it had been Zhang Tie’s obsession rather than his whim…

Since Zhang Tie entered the theater of operations and saw numerous commoners evacuating from their hometowns and so many cities being destroyed and abandoned and the surging tide of demon army that crossed so many provinces, this obsession had gradually been strengthened in Zhang Tie’s heart. After eating the last meal of Ancient-well bean curds in Xiangshan City, this obsession became clear abruptly.

Additionally, Zhang Tie had already aimed at the power of having commoners resist even kill demon knights——kinetic strike!

The energy of kinetic strike of Zhang Tie himself originated from his ability as a divine dominator. As for commoners, if they could acquire the necessary speed and energy required by the kinetic energy through mechanical equipment or steam dynamic devices, they would make it come true too.

Before the Catastrophe, humans had already invented kinetic weapons. Within days, Zhang Tie was racking his mind to try to have kinetic weapons reappear in the world. As long as humans got hang of kinetic weapons and each Class A city in Taixia Country was matched with such a weapon, the scale of the holy war would completely tilt to one side. By then, the combat pattern of the holy war would change.

In case of the proper place for attempting to make devices and weapons concerning steel and steam, Heavenly Craftsmanship City in Taixia Country would definitely rank first.

Coincidentally, Heavenly Craftsmanship City was also in Military Province, right in the rear end of the area under the jurisdiction of Weiji General. After making a short inspection of this city with Lu Yanyu by airboat, Zhang Tie had already made a decision.

After coming to Heavenly Craftsmanship City for 2 months, this kinetic weapon was still a concept and barely in its embryo. However, Zhang Tie had already promoted to 9 change realm of earth knight…
