The experience of the dwarves and goblins was very precious to Lin. Whether it was their secret methods of metal processing or their understanding of the combination of different metals, they were not something that a self-taught Mage could compare to.
Welding was needless to say. Whether it was the dwarves or the goblins, even Lin had made some adhesives for magical metals before. These adhesives were actually made of other magical materials. A good adhesives could not only connect two different metals together, but could also connect the power transmission between them into a whole.
As for the problems of high temperature and aging, they did not exist for most adhesives made of magical materials. To remove the state of adhesives, there were corresponding potions. The potions had different compositions. As long as the right medicine was not used, it would be impossible to remove the adhesives.
This was also one of the reasons why the dwarves and goblins regarded these methods as secret methods. No one wanted their potion formulas to be leaked so that others could easily destroy their work.
As for the same materials, it was even easier to deal with them. A magical molding spell could knead multiple materials of the same material together like playing with clay.
As for the problem of sealing, it was a little more troublesome. Previously, Lin had wanted to find rubber or a similar plasticized product from crude oil to make a seal. However, the dwarves and goblins both gave him a very mysterious way to solve this problem.
When joining materials of the same material, they could be fused into a whole with molding spells. There would be no joint points, so there was no need to consider sealing. However, when joining materials of different materials, the first step was to stick the two metal ingots together with an adhesive. Then, with the combination of molding, high temperature, and forging, the three-pronged method could force out the bubbles that might exist at the joining surface.
On Earth, when two objects were fixed together, because the parts had already been formed, there would inevitably be some gaps at the joint surface that could not be seen with the naked eye. In order to fill these gaps, the help of materials such as compaction and spacers was needed.
However, in the mysterious land, it was normal to treat the objects as a whole after bonding and molding and processing them. During this process, making the possible bubbles and gaps completely invisible was the most basic operation for the craftsmen in the mysterious land. And such a basic skill was "common sense" that a Mage who did not have a teacher who specialized in making artifacts would not have.
It seemed that the principle of 'different professions make one feel like they're separated by mountains' was also applicable in this mysterious land.
For example, a magician could make the appearance of an object very beautiful and add powerful magic to it. But when it came to making basic items to the extreme, he still couldn't compare with the Dwarves who had been working with metal for most of their lives.
As for the experience of the Gnomes, he dared to try. He found a 'passable' path in the midst of endless mistakes. But to Lin, the most valuable mistakes were those that had been proven to be unworkable. Taking fewer detours meant getting closer to the correct answer.
With the combination of the advantages of these three races and the knowledge that Lin Sheng had learned before he transmigrated, they worked together to create a never-before-seen mechanism and a fuel engine made from magic materials. In fact, he wasn't sure how far this engine could go. There was no such thing as authority on Earth. It couldn't be that because of Authority, the engine was enchanted with nitrogen, right?
Perhaps this was a good train of thought. On Earth, the nitrogen-oxygen acceleration system couldn't be used routinely because of the strength of the material of the engine itself. It couldn't withstand high temperatures, high speeds, and long periods of operation. But the materials used to make the engine were all specially selected by Lin Sheng. They were magic metals that had high temperature resistance, toughness, and hardness.
But he shouldn't bite off more than he could chew for the time being. In terms of experiments, the engine before him was not only the first power device that he had built, but it was also full of all kinds of experimental ideas. If these could work normally, he would consider other things.
Finally, he had come to the test run for who knew how many times, and this time, he was more confident than the previous few times. Because there was no specialized machine to measure horsepower and torque, Lin Sheng could only make simple judgments based on the changes in the accelerator, the speed, and the time it was maintained.
The reason why the previous engines were rated as failing was because the speed would drift when the accelerator was maintained at the same speed. Sometimes, the speed would even decrease. The possible reason was because of the uneven weight distribution between the crankshaft and the pistons.
Because everything was handmade, even with the help of blueprints and rulers, it was still difficult to avoid subtle differences. In particular, the dwarves and goblins didn't care about these small differences.
After experiencing several failures, they began to pay attention to these small things that they didn't care about before. In fact, Lin Sheng could understand what they were doing. Because for a single piston, no matter if it was dwarves or goblins, they could achieve the exact same weight, and the shape would be perfectly round without any deviation. That was because they had been constantly refining their own techniques all this time.
But they had never done something like this, where they had to combine different parts into a whole. If there was something similar, it could be said that it was a full-body armor. But a good armor maker would make slight adjustments based on the user's habits and physical characteristics, and would not achieve perfect symmetry.
It could be said that this was the first time that they had to replicate their own perfect work, and it had to be exactly the same, without the slightest deviation. In this aspect, Lin Sheng didn't have the skills of dwarves and goblins, so he could only do the job that was most easily complained about: quality control. He was responsible for telling others that the quality of the products didn't pass.
So, after several failures, he believed that Jermaine and Totokani believed that it was not as easy as he had imagined. Moreover, he pulled himself together and became extremely serious. In the end, there was this confident work in front of him.
Speaking of the previous engine, they said that it was a confident work. Then, when it was started, there was a violent vibration, and in the end, it even fell apart. A certain someone was left speechless.
Jermaine skillfully connected the measuring instruments to various parts of the engine, and after filling it with fuel and lubricant, he immediately started the engine that he had high hopes for.
The lubricant was refined from animal oil, and it took a lot of effort to remove the protein components in the oil. But the effect was unexpectedly good, and it didn't lose to the synthetic oil used on Earth at all.
After the magic stone that replaced the spark plug flowed through, it immediately produced a slight current, igniting the oil and gas in the cylinder, and the engine started smoothly. In the idle state, the speed of the engine was maintained quite stable. And the vibration of the main body was much weaker than that of the previous test works. This meant that the internal weight was well balanced, so there wouldn't be excessive vibration.
As the accelerator was increased, the amount of fuel injected increased, and the speed was further increased, and the situation was stable. And when the level of the temporary small fuel tank reached the warning line, the experiment was declared a success. This meant that a certain amount of fuel was consumed, and everything was in good condition, so there was no need to stop the experiment.
If it was on Earth, the experimental model of the engine couldn't be commercialized without tens of thousands of hours of continuous operation. But there was no time for that now, and there wasn't enough fuel to waste, so Lin Sheng directly let Jermaine and Totokani start the production of the second engine, and he had another job.
But before that, he had to ask the Silver Bearded Dwarves for something.
"What, you want to use the energy center of the peaceful armed forces on the airship?" Jermaine shouted in surprise.
"Strictly speaking, it's the special magic stone mechanism inside, the control assembly will still be preserved." Lin Sheng calmly replied.
"But this way, the peaceful armed forces will be scrapped. I can't agree to this. "
"First of all, I have to say that for everyone's lives, Totokani handed over his airship, and I also contributed most of the materials I collected. I just want a special magic stone mechanism from you, and I haven't dismembered the peaceful armed forces yet. Besides, after this period of waiting, do you still have hope for the energy center to recover naturally? You've seen the measured values yourself, from the middle of last year until now, more than half a year has passed, and the energy center's recovery rate is less than one percent. Instead of waiting for the peaceful armed forces to recover, it's better to find a way to introduce other ways to use the power. Actually, when you agreed to let me research the peaceful armed forces, I already had a plan, but I couldn't find the right materials, so it was delayed until now. And if we want to get out alive and repair the peaceful armed forces, the special magic stone mechanism is indispensable. "
Lin Sheng didn't say anything definite, and he also promised to help repair the peaceful armed forces' energy center. More importantly, according to the current progress, it might take thousands of years for the peaceful armed forces to recover naturally.
For example, if a person had a hundred million dollars in his bank account, and he lost a hundred thousand dollars, the remaining money would eat the bank's living interest, and it would only take a few months to recover the loss of a hundred thousand dollars. But if the account only had a hundred and ten thousand dollars, after losing a hundred thousand dollars, and relying on ten thousand dollars to earn living interest, it would take a long time for the account to recover a hundred and ten thousand dollars.
This was the problem that the silver-bearded dwarves' peaceful armed forces faced.
As for the special magic stone mechanism that he intended to use, it was like a battery that was responsible for storing large amounts of Authority, although the battery was empty at the moment. Lin Sheng intended to modify it into a simple energy pool on the airship, and connect it to the magic array of the entire ship. Although it couldn't produce power on its own, it had to at least be able to store power, so that the airship's endurance could be guaranteed.
First, they understood the current situation; second, the silver-bearded dwarves weren't as stubborn as before; third, as Lin Sheng said, hoping for the energy center to recover to a usable state might take a long time. Rather than maintain the current state, it was better to trust this mage again.
So, although the silver-bearded dwarves were still reluctant, they still agreed to hand over some parts of the peaceful armed forces.
