Castle of Black Iron

Zhang Tie kept practicing what he had learned in the rune instrument manufacturing skill promotion region as the bath place was gradually improved...

Even if Yan Feiqing was not there, Zhang Tie would also take it as something interesting. If battle strength was not considered, rune instrument manufacturing masters were those who could almost change the world mostly with their intelligence and manipulative ability.

Pharmacists were excelled in making medicinal pills. What people ate all belonged to the research field of pharmacists.

Alchemists were proficient in stones. Concretely, gems, semi-gems and crystals. Alchemists could definitely touch a stone and turn it into gold. After being treated by alchemists, those gems, semi-gems and crystals which were originally decorative would always carry marvelous effects like having been blessed by buddists or the God. They could match medicinal pills in curing diseases and strengthening people's body; improving equipment attributes as effectively as runes. Of course, what made people awe-struck most was alchemists' ability to make alchemists' bombs, which was, as of now, the only object that could be used to kill knights on specific occasions.

Rune instrument manufacturing masters were good at melting and forging metals.

The early stage of rune instrument manufacturing master; especially the stage of craftsman apprentice and craftsman was like technicians, engineers and blacksmiths in plants. If a fresh rune instrument manufacturing master was put into a blacksmith's store or a plant, it was nothing different than putting a drop of water into the ocean.

The middle stage of this profession was equal to the advanced stage of technicians, engineers and blacksmiths as they could almost make all kinds of machines using metals ranging from a tiny ordinary screw to a complex steam turbine. All the relevant knowledge was in the mind of rune instrument manufacturing masters. In this stage, rune instrument manufacturing masters started to make big items such as machines, sabers, swords and helmets and gradually made them more delicate. Additionally, their scope of business started to expand. Any experienced silver hammer craftsman would have adept skills in fine arts and sculpture. If a silver hammer craftsman was put with those craftsmen who could make fine and delicate jewelry, their real identity would also not be identified.

Since Zhang Tie took the fruit of plunder from Old Master Jiang, he had already grasped the profound skills in fine arts and sculpture. However, Zhang Tie didn't show it in the public. With such proficient skills, he would be qualified as a professor in fine arts or sculpture in every university in Waii Subcontinent.

Starting from mithril craftsman, they had officially entered the advanced stage of rune instrument manufacturing masters. In this stage, rune instrument manufacturing masters started to contact higher-level metals and comprehend the mystery of combining metals with runes. In the stage of the major craftsman, they had reached a superb level in comprehending the mystery of metals and runes.

Crafstmen masters had reached personal sublimation in each realm being involved with this profession. Craftsman masters were masters in processing and applying fine art products, sculptures, metals and machines manufacturing. From the purely artistic perspective, fine art works or sculptures of craftsmen masters were almost overhwelming against all the works of the so-called masters who were simply immersed in arts. In Taixia Country, all the top painters, sculptors, sword makers and steam engineers were unexceptionally craftsmen masters and above. Additionally, craftsmen masters had been able to use runes array.

Immortal craftsman was the apex of the profession of rune instrument manufacturing master. The symbol was that they were proficient in using runes array and had reached an immortal realm in all the other regions concerning this profession.

Preoccupation could bring people a bizarre strength. As long as people were immersed in something, they would have many discoveries and more happiness.

That was also Zhang Tie's current state. He found it very enjoyable to turn what he thought into reality and gradually improve this wilderness. Everything that he could experience in this process could never be matched by fruits of plunder.

He didn't have stress facing cultivation, tussle, hideous demons or despicable enemies here; he only needed to do whatever he liked here.

When he was free, he would recite the endless true words of Great Wilderness Sutra or read some books in the library in Xuanyuan Hill or the database of the Rune Instrument Manufacturing Masters Union. The process of having such a rest was also a rare enjoyment.

During this process, Yan Feiqing's "bath place" also changed day by day.

After making steel, Zhang Tie had a greater ability to renovate this wilderness. Besides making various molds and tools using the steel that he had melted and upgraded his metal processing desk with them, a few days later after he made steel, Zhang Tie had made the first batch of special alloy in the method of powder metallurgy.

Zhang Tie made the first set of 7 treasured wares manually using the first batch of a special alloy that he had just made. The independent production of 7 treasured wares symbolized that a craftsman apprentice had promoted to a craftsman officially.

The 7 treasures wares of rune instrument manufacturing masters referred to 7 simple tools, which included one hammer, 3 metal files, metal slicers and gravers in different specifications.

As for qualified rune instrument manufacturing masters, as long as they carried the 7 tools and had enough raw materials, they would almost be able to make everything. One of the standards for a qualified silver hammer craftsman was whether he could keep the precision within 1/100 of the thickness of hair when he processed a metal ware manually by any file or graver. The precision should be limited to 1/1000 of the thickness of hair for major craftsmen. A successful rune instrument manufacturing master was a set of the movable precision lathe with the set of 7 treasured wares.

After Yan Feiqing took her bath for a few days, Zhang Tie had made the first set of steam pumping machine and the first set of a steam boiler in the wilderness; additionally, he even made some steel pipes.

With these items, Zhang Tie upgraded the bathplace once again.

Zhang Tie paved two pipelines at the bottom of the brook in its upper reach. He drew water into the steam boiler by steam pumping machine and heated it inside. After that, he introduced the hot water back into the pool. After commissioning it twice, the cold water in the brook was heated and maintained a temperature of 41 degrees Celsius, which was suitable for bathing...

1 month later, when Yan Feiqing came here for a bath once again after her closed cultivation, she was stunned by the enshrouding vapor over the pool. She had not imagined that Zhang Tie could heat up the water in this environment...

Yan Feiqing didn't leave until 3 hours later.

After taking a hot bath, Yan Feiqing's face looked red and shiny, making her more fetching and enchanting. At the sight of Yan Feiqing who exited the crystal Mongolian yurt, Zhang Tie couldn't stand widening his eyes as he swallowed his saliva twice stealthily.

At the sight of Zhang Tie, Yan Feiqing slowed down as she glanced over Zhang Tie as if she had recognized Zhang Tie once again, "I've not imagined that you could have a gift to be a rune instrument manufacturing master. It's amazing that you could make that in only 2 months. However, if you don't form your chakra here, it would be too pitiful. As for knights, cultivation base counts most. Even if you could promote to an immortal craftsman within 60 years, it would not be as meaningful as promoting to a shadow knight..."

"Do you care about me?"

Yan Feiqing thought that Zhang Tie started learning rune instrument manufacturing skills from scratch. Zhang Tie didn't explain it to her; instead, he flirted with her.

"Harrumph..." Yan Feiqing turned icy as she turned around and left right away.

Zhang Tie smiled. If he greeted her like this when he saw her at the beginning, he would definitely be hunt down by her; however, she only replied with "harrumph". What did this mean...

After stroking his jaw, Zhang Tie returned to the crystal Mongolian yurt.

...

As time went by, the two people were still doing their own business independently.

Although shadow knights could enter closed cultivation for a long time, they had to take rest too; especially in the tower of time, relaxation was very important as she had to stay here for 6 decades. If she always behaved intensely, she would be tired sooner or later. Zhang Tie gradually found that Yan Feiqing had regarded taking bath as a pattern of relaxation.

After each 30-day cultivation, Yan Feiqing would come here for a bath. After that, she would go back for sound sleep and continue her cultivation on the next day. Since she was molested last time, she had not talked with Zhang Tie for 2 months, during which period, she remained silent even if she had seen Zhang Tie twice. Zhang Tie just passed by her without flirting.

Over these months, Zhang Tie continued to check what he had learned about rune instrument manufacturing skills as he further renovated that pool in the wilderness.

On the 3rd month, he had built a stony mermaid sculpture which could spray hot water in the pool.

Sitting on a piece of rock in the pool, the mermaid was holding a conch. After being heated, water would spurt out of conch which served as a shower device...

After this mermaid sculpture was completed, Yan Feiqing made her bathing time longer...

On the 4th month, Zhang Tie made a brick making machine and expanded his kiln in the wilderness. Additionally, he built a new kiln which could help him bake bricks with over 100 times higher efficiency. At the same time, the marlite that he got from the wilderness served as a raw material for the simplest natural cement after being baked by the new kiln.

With the assistance of this brick making machine, Zhang Tie baked a lot of bricks. He then paved over 6,000 square meters' land around the pool. Zhang Tie then erected a wall around the pool using bricks and cement. He even built a house with two isolated courtyards.

Zhang Tie didn't have experience in being a construction worker. However, it was not difficult for a knight and major craftsman to build a house. After reading over 10 engineering books in the library of Xuanyuan Hill in his trouble-reappearance situation, Zhang Tie had been more proficient in housebuilding than most of the construction workers...

After entering the tower of time for half a year, Zhang Tie had given Yan Feiqing a big surprise...
