Here’s the last chapter from Silent, please go check out his current translation, Legend and thank him for these 4 chapters.

04-04 Golem Engine

After making a set of legendary accessories, Jin took a break. Soaking in a bath at dusk was refreshing.

「Ah, we’re doing well, we managed to get several ideas afloat.」

As Jin leisurely leaked a murmur, Reiko was watching from the side.

Now Jin wanted to make a motor engine for rotational motion.

「How to make the rotational movement from foot pedals……」

At that time, an inspiration struck Jin.

「That’s it.」

「Golem Engine.」

「The idea is turning the crank shaft by incorporating the same mechanism used in a golems arms and legs to replace the pistons.」

Jin didn’t know the difference between a 2 stroke and 4 stroke engine, but he knew enough to make an engine.

「I can try to make a prototype in bronze.」

Bronze is a material commonly used because it’s easy to shape with magic. Naturally, Jin thought to make a prototype out of this.

In the end, a prototype of the Golem Engine was completed before dark. It was about 50cm tall.

「Alright, time to commission this before dinner. ……Start!」

Inside, the drive mechanism starts to move and the crankshaft turns.

「Oh, it’s turning, it’s turning.」

It was found that the speed of rotation could be increased by pouring in more mana.

「Hmm, as I thought, this is the limit.」

The limit was roughly 300 rpm. As this was going to be cranked by hand, it was unlikely to be raised above this number of revolutions.

「Reiko, can you try to stop the shaft?」

「Yes, I’ll try.」

Reiko held the 2cm diameter shaft at an output of 5%. Although the speed of rotation slowed, it didn’t stop. It finally stopped at 10% output.

「Right, thanks Reiko, the Torque (rotational force) is quite something. It could even go in a car.」

(TLSilent: double check second half of sentence.)

It remained durable.

「Since we’ve found the max rotation, it’s time for dinner. Reiko, don’t stop it but tell me if the situation gets bad.」

With that, Jin headed for the ‘Mansion’ outside. Soleil and Luna made the daily meals there.

「It’s Soleil today. She seems accustomed to it.」

(TLSilent: I think this is what it means?)

「Yes Father.」

There was wheat porridge, bread and tea. For tea, Reiko would sneak back to Kaina village in the middle of the night to take some tea leaves. The seedling would only produce drinkable tea leaves several years after being planted.

Eating wheat porridge, drinking tea and spreading marmalade on bread. Recently, a plant similar to strawberries had been found and strawberry jam was made. Thinking about the durability of the engine, Jin quickly finished dinner and went back to the laboratory.

「Oh, Father.」

「How is it?」

「Yes, it’s working without any problems.」

「Let’s see.」

The Golem Engine was too hot to touch. The piston didn’t have a heat sink, so this was only natural.

「Alright, let’s stop it.」

When Jin stopped the engine, he took it apart. This was to determine if any parts were worn out or damaged.

「Uh huh, as I thought, the damaged parts are mostly the golem parts. An Adamantium skeleton with muscle tissue made by twisting magical fibre is best.」

If you thought that the constitution was similar to Reiko’s, you wouldn’t be wrong.

「Well then, let’s get the production started. Reiko, get me some Adamantium.」

Asking Reiko to get the heavy Adamantium, Jin went to get the magic fibre and Magi Crystals on his own.

「It’s finished.」

Late at night, the Golem Engine was completed. The crank and shaft, which were supported by ball bearings, was mostly made with Adamantium. The golem parts were strengthened with multiple reinforcements.

As a result the torque was increased to nearly 3 time that of the trial. Reiko only stopped the shaft after raising her output to 20%.

「Finally, I have to make gears now.」

With that, the day’s work was finished.

The next day, Jin began to seriously consider making gears. He had tried making them before but when they were put together they were stiff or loose making them useless.

Even Magi Craft Meisters had a weakness.

The Magi Craft Meister’s ability was similar to a 3-D software drawing system. By default, the basics shapes of balls, discs or cubes could be copied.
