Chapter 159 Strange Iron

"It's ours now!"

"You can do research with confidence."

A group of dwarves surrounded the clockwork frog, their faces full of excitement: "Take it apart and have a look."

Black Hammer Chief: "What a rush! We can't dismantle it here. Let's go back to the crypt and do it."

The dwarves didn't even have the mood to say goodbye to Zhang Jingyi. They all drilled into the dungeon, even the sentinels went in.

Zhang Jingyi spread his hands: "These guys have even withdrawn their sentinels. If we are attacked by a hostile race at this time, won't everything be over?"

Luna grinned, "It's okay. Dwarves are famous for their toughness and strong fighting ability. Even if they are attacked by surprise, they can handle it."

Zhang Jingyi: "Then let's go!"

Luna asked curiously, "Are we leaving now? Isn't His Majesty going to learn enchantment techniques from them?"

Zhang Jingyi: "If you ask others for something, you will be looked down upon. It is better to wait for them to come to me and give me the technology. I have planted a seed, and now I just need to wait for it to sprout and bloom."

Luna: "Oh, what a hassle."

In the deepest part of the dwarven dungeon, the lights are brightly lit next to the furnace.

The Black Hammer dwarves lit up every lighting source they could find, making the entire room as bright as day.

All the craftsmen in the tribe, in fact, all the young and middle-aged men, were there. Several old dwarves who had lost their fighting ability also participated, as they were the treasure trove of wisdom of the Black Hammer dwarves.

Everyone stared with wide eyes as they watched the Black Hammer Chief carefully study the clockwork frog.

"Look, this shell is held in place with nails!" said the Black Hammer tribe leader. "This nail is very strange. It is not driven in directly, but spirals in."

"That's a screw!" an old dwarf spoke up.

It turns out that in Zhang Jingyi's world, screw technology was born in the 15th century. In this world of swords and magic, the dwarf master craftsmen have already mastered the technology that human craftsmen have not yet mastered.

The old dwarf said, "To remove this screw, you need to make a screwdriver of the right size. The front end must be cross-shaped... This is not difficult. I believe you can do it."

Chief Black Hammer immediately started working under the guidance of the old dwarf. He pulled the bellows, and a group of dwarf craftsmen came to help. There was a clanging sound, and then there was elaborate work and careful carving... In the end, a beautiful subcompact Phillips screwdriver was made by them.

The Black Hammer Chieftain couldn't help but feel satisfied with his own skills. He managed to make such a tiny screwdriver so beautifully. Hehehe.

He inserted the screwdriver into the cap of the screw and turned it. The screw was slowly pulled out.

The old dwarf picked up the screw and looked at it, with a look of admiration on his face: "What a powerful screw, pass it around, does anyone have the confidence to make such a powerful screw?"

The dwarves picked up the screws and looked at them carefully, and the expressions on their faces were very interesting.

Obviously, no one dares to say that they can create something like this!
It's so fine, every thread is equal and perfectly spaced.

The old dwarf thought seriously for a long time and said, "I can only think of one way to make such a screw. That is to make a perfect thin wire first, and then wrap the wire around a thin iron rod at an angle. Then, cut marks on the iron rod along the gaps between the wires, and this will form a uniform spiral pattern."

The dwarves were full of admiration: "Master Craftsman, your wisdom is amazing."

The old dwarf said, "I just thought of this method now, but the person who built this mechanical frog had already thought of it and built it. He is really an admirable master craftsman. I also want to learn from him."

As soon as the dwarves began to dismantle the frog, it taught them a lesson.

I can't help but admire it even more.

The Black Hammer Chief carefully unscrewed all the screws and opened the cover of the frog with extremely gentle movements. The contents inside were finally exposed to everyone.

The dwarves' brains immediately felt slightly blocked.

"Is it so simple inside?" "I thought it was super complicated, with a mechanical heart."

"Yeah, it's so simple, how does it move?"

"Hold it and see how it works."

The Black Hammer chief gently lifted the mechanism and saw that the circles of things were slowly tightening. Then, as soon as he let go, the circles of strange things began to bounce open, driving the gears, and the frog jumped up.

Everyone: “Wow!”

“I understand!”

“I understood it immediately.”

“It’s this… that’s the motivation.”

“This thing can actually provide power?”

"What is this black, circular thing?"

"It's a thin sheet of iron!"

"I feel like I can do it right away. I seem to know how to make it."

A dwarf craftsman immediately ran back to his workstation.

He picked up a piece of red-hot iron with a pair of tongs and banged it with a few bangs. Soon, it became a thin piece of iron sheet. Then he cut it into a long strip and slowly rolled it up...

He was not the only one working on this. Several dwarf craftsmen returned to their workstations, all making the same thing.

Not long after, several dwarves came over with the "tin rolls" they had made.

"Look, I succeeded!"

"Haha, it's a piece of cake."

“This process is too simple for us.”

The dwarves couldn't help but feel proud. As a race, they didn't value the modesty of humans or the low-keyness of elves.

Once they have achieved something, the dwarves will sing, dance and drink, fearing that others will not know their greatness.

They happily took the iron rolls they made to the master craftsman for review.

The old dwarf took the iron roll, gently bent it with his hands, and then frowned deeply: "No! What you made is not up to standard."

Dwarves: "Ah? They are exactly the same!"

Old Dwarf: "Your iron rolls are not elastic. If you roll them up tightly, they won't bounce open."

As soon as the dwarves woke up, they rushed to test it and made a mechanism to tighten the iron roll.

Sure enough, the master craftsman was right. The iron rolls they made would not bounce back once they were held tightly, and could not provide any power at all.

"It's not good!"

The Black Hammer tribe leader immediately realized: "The black iron roll in this mechanical frog is not made of ordinary iron. It has strong elasticity and toughness. After being tightened, it will loosen due to its own elasticity and return to its original state. The iron we smelt does not have such elasticity."

The master craftsman said: "That's right! The key to the problem lies in this piece of iron. Children, let me see your skills. Who can smelt this strange iron?"
