Steel steam and flame

"Thank you, distinguished guest, for coming here." The butler saluted and said, "Please come upstairs." He said, and the two people behind him moved and stood aside. The three of them were all looking at Silla's feet, and they were thinking about this time in their hearts. business has been understood.

After going up to the second floor, a skinny mechanic came down with a smile and a loudspeaker in his hand. The handle on it was so worn that it shined from long-term use. All the negotiation matters were left to Lina and Delya, and it went very smoothly. The other party had no work to do. All the agreements and contents were quickly discussed, and the price was also satisfactory.

Then, led by the housekeeper, they all came to the basement. The spacious basement, a foothold in the world of mechanics, is now open to Cassia.

There is a huge furnace in the center of the basement, and the exhaust gases are discharged elsewhere along long twisted pipes that are all grounded. There are also light blue flames burning inside, releasing huge heat to the surroundings.

"It is used to smelt high-grade alloys, and the temperature can reach a high temperature of more than 10,000 degrees for a short time." The steward introduced, "But the temperature is still not enough. Among the metals we need, about half of the metal types cannot be smelted. Completely melted and smelted. The owner has wanted to change to a higher-standard furnace for a long time, but the channel was cut off not long ago, and the price is several times more expensive if he takes the dark world route. Alas..."

I don't know if the housekeeper sighed intentionally, but Cassia didn't pay attention to it. Instead, she tried her best to remember all the novel equipment in her mind within the visible range. Go back to the military school, and the permissions of the second-floor library should be opened. Then everything can be checked.

Linna was talking to the mechanic about Sheila's prosthetic limbs, and it seemed that other problems had arisen.

"No, no." The mechanic's temperament is very easy-going, which is completely different from the cold machines in the basement. "Your requirements must be met by a professional doctor. If you don't have the coordination of a doctor to deal with neurological matters rashly, I am It's completely unprofessional. The prosthetic limb can only be controlled sub-accurately through the contraction of the muscles in your sister's leg. If you want to achieve the same performance as the original foot, even if you use the current circuit board components to connect the nerve signals, it is completely impossible. No. And I don’t have that kind of expensive device here, and it doesn’t exist in the dark world. Even if there are goods circulating, it’s not something that we can grab. I don’t think you can afford the price of that thing, either. It's something from top scientific research institutions in major countries, and the core technologies have been blocked. If you have the channels and relationships in that area, I think it's possible."

"The most I can do here is bury the relevant circuits in the prosthetic limb in advance to facilitate making relevant changes later." The mechanic said, "I can give you a discount on the materials and use the best alloy here. How about it? And Miss, you also know that the stability of things like circuit boards is really... indeed, their practicality in the world of ordinary people is surprisingly good, but in other areas, gears and steam are more stable. . Otherwise, with the energy and convenience brought by PV tubes, the popularity of electricity should have spread to every corner of this continent."

Linna was somewhat disappointed, and so was Silla. The current biotechnology has not yet reached the stage where severed limbs can be regrown. Of course, things related to dragons have to be excluded.

The manufacturing process of the prosthetic limb is completed step by step. The mechanic's body is thin and skinny, but he has great strength. The installation and assembly of many things rely on his fingers. Only the core parts require machines to ensure precise accuracy requirements.

Cassia did not stand aside to watch the process, he turned around in a circle. There was a glass cabinet with finished products in one corner. Inside, he saw three brand-new pneumatic weapons, all of which were swords and had different styles.

"Is the customer interested? I can sell it to you at a cheaper price." The butler walked over with a shrewd look, "They are all finished products. Some customers who stayed here because they failed to pay the final payment for various reasons can be given priority to sell them to you. It is powered by energy and can be used immediately. The workmanship is excellent and can be changed according to your usage habits if necessary.”

"No, just looking." Cassia shook her head and said.

"That's really a pity. Recently, many mechanics in this area have been forcibly summoned back. Soon, it will be time for us to leave here and return to our own country." The steward said, "At that time, I wanted to buy at a low price. It is impossible to get these things. In the dark world, there is no possibility of the price of pneumatic weapons falling... The leisurely days are almost over. If you want to be a free person, just the weight of a few of us is It’s not enough at all. There still has to be a powerful background behind it. In the gray area, the value of these machines is enough to make people jealous..."

The housekeeper sighed there, and Cassia stood silently with the shadows of the swords in her eyes, no longer moving.

The production of the prosthetic limb was completed around twelve o'clock in the evening, but the related debugging continued until the early morning of the next day before it was completed through the difference engine.

Finally, a layer of soft material was put under the prosthetic limb so that the sound of Silla's walking on the ground would not be too loud.

The level of satisfaction is okay. The weight of the prosthesis is not a problem at all for surgeons who have abnormal weight. The quality of the alloy is very good, and the word from the machinist is that a head-on encounter with any platinum bullet of any existing caliber will leave only scratches and shallow pits at best.

Finally, after paying the money with a bank card, Cassia and the others immediately drove to the train station according to the route decided in advance without stopping.

During the drive, all four of them had to put on makeup to change their appearance.

Before reaching the station and still on the road, Cassia and the others encountered convoys from various forces. Presumably the small airship must have reached the mechanic before these cars. Their location was quickly exposed through transactions on bank cards. Sure enough, the confidentiality agreement for users mentioned in Golden Bank is really just an agreement in front of the big forces.

Abandoning the car in a small alley in the city, the four of them finally separated on a roadside and ran to their respective airports and train stations.

"I don't know how long it will be before we see each other again. It would be better if we don't see you on the battlefield then." Lina said with a smile, putting on a light yellow wide-brimmed hat to block the scorching sunlight that just appeared.

"No." Cassia said, but everyone knows that after becoming a surgeon, or a strange person as Lina and others call it, no one can avoid being involved in the war in the near future.
