After being told that he could travel if he wants, Jin went back to Hourai island in great joy and started preparations for his trip .
Â
âNow then, letâs get the carriage ready first . â
Â
The carriage he had built back in Egelia kingdom still remained, but after assigning the equipped warp gate for other uses, it would be a bit of a bother to put it back .
Laojun had been putting together a carriage of similar type for this occasion . Jin thought he would make a new model from scratch .
He made the outward appearance similar to the previous one .
Of course, he also equipped the warp gate .
With four-wheeled, self-support suspension system, âActive suspensionâ .
Fully furnished air-conditioning .
Floodlight projector .
And, of course, the horse would be a golem horse .
This was what would usually be equipped but from this point on, Jin did the unthinkable . Â
âI guess I will make it so that it can run even without a horse . â
Â
In other words, he planned on equipping it with a golem engine so that it would be capable of running on its own .
Â
âI canât really pack in a big engine which stands out so I guess I will have to go with the least possible one I can . â
Â
He isnât aware that his âleastâ isnât what is considered to be the general âleastâ .
 âFather, I have prepared the materials . â
Â
Reiko brought aluminium 64 . It is much stronger than normal aluminium .
Â
âAlright, letâs start . â
Â
Not having to worry about anyone watching, Jin exerted his engineering magic as much as he wanted and kept on processing the materials . Reiko was supporting him .
Moreover, Laojun was considerate and called over two Smith golems . And before one knew it, the carriage was completed .
They used the sea dragonâs leather for the tire . Due to its roughness being similar to the dragonâs scales, its grip power is extraordinary, even above boulders . (In fact, the boulder might break instead . )
Â
âAs I thought, we donât get much speed if the golem engine is small . â
Â
Jin grumbled as he saw the carriage go through the test run .
The engines are small as they have been equipped to each of the wheels . It looks like nothing but a fat tire but, in fact, golem engines are installed next to it .
And due to this, he couldnât install anything too big as it would stand out too much . But it is also true that that would decrease the torque . It would be able to reach a speed of about 40 kilometers per hour .
