The Book of Program Writing.
This was the name Sylus gave to the new studies he discovered.
It was a massive branch of spell writing—or the improved version, depending on how the mages decided to view it.
Not that Sylus cared anyway; he just wanted to ensure the car would be a success.
While Zani and the soldiers were busy building the frame of the car, he sat at the side, multiple brown papers scattered before him.
Brown papers were used by mages to write spells, which were then turned into runes.
According to what the soldier told him, he needed to beg his commander, using the prince's name, before he could get his hands on them.
Sylus didn't know how they were made, but they had to be valuable to some extent.
Anyway, with the magic pen in his hand, Sylus was ready to finally put into practice what he had been learning.
If he were to write it off the top of his head, it could take him multiple tries, but since he had already written a huge part of them down, it should be fairly easy.
'Unless everything I wrote in here is wrong.'
He gulped down his saliva.
Holding the magic pen firmly, he began writing.
The first spell was for rotation.
This meant that the runes he was working on would cause items or anything they came into contact with to rotate.
Normally, if he was writing with the original spell writing, once he was done with the spell, it would give off a bright color to hint that it was now working.
His program writing was quite different.
After writing the last character on the stone, Sylus waited in anticipation.
'Did I get it?'
Answering his question, the brown paper began to glow.
Sylus kept a calm face; he knew it wasn't over.
As the light dimmed, he pulled his face closer.
Every character that was written on the brown paper disappeared and then formed into a single "№" symbol.
A smile quickly formed on Sylus's face.
'It worked! I did it, hahah!'
Not wasting any time, he began to write the rest of the spells.
Spell for balance, spell for reversing, spell for cooling and heating.
Sylus made runes for every single one of these attributes.
And once he was done, he did the next part—the part many mages had failed to do for years.
Using his language, he merged every single spell inside one brown paper, giving them both a variable and a loop to create a constant flow of codes and spells.
What if it exploded? What if he miscalculated one symbol?
Sylus paid those thoughts no mind.
By the time he was done, he had already created a single rune in the entire kingdom that could serve multiple purposes.
'I'm done!'
He raised the already hardened brown paper, his eyes sparkling with accomplishment.
Of course, he still needed to be sure they would work as coded, but for now, he had already earned himself some praise.
Besides, there was still a lot of time.
As he looked toward Zani's location, he could see they were also almost done with the frame of the car.
If it were made with iron, it would have taken more time to complete.
But with wood, it was easier and faster—no different from making a wagon.
Sylus stood up.
It was best to leave the two alone; they seemed to be focused at the moment.
Thus, Sylus moved to the next task, which was making the engine of the car.
He knew it was going to be tricky to make, considering he had never made one before.
That said, with the little knowledge he had from his former world, he could still put up a challenge.
Everything he needed was present; all he had to do was set them right.
'Yosh, let's do this.'
He began assembling the engine.
There was already a wooden box with a hole on the side for him; this was where he planned to put all the components.
The first thing he took care of was the Mana Conduction.
The function of this component was to draw mana from the mana stone and distribute it to the areas of the car that needed it.
For this, Sylus used a conductive alloy orb, bought from a mage, as he was told.
He set it at the center of the box. It had no light, although that was because it hadn't been connected yet.
Next, he added the runes, safely gluing them to the floor of the box after he had glued a bunch of wires to it.
Each wire was wrapped with brown paper, with a single character written on it, linked to different functions of the rune.
With that done, he connected the wires to the mana conductor and then left a few wires out to be connected to the car later on.
Elemental converter—which was just a small tube, with the rune of cooling and heating connected to it.
Directional reversal node—a circular rune chamber that activates when the reverse button is pushed.
Sylus made sure to add every single component that was needed for the car to operate well.
By the time he was done, it was already nighttime.
And as expected, his eyes were beginning to close.
Sitting in front of the engine, Sylus took a deep breath.
'Oi! Don't go sleeping; you're almost done, just the battery… just the …'
His eyes closed, his body already losing balance.
He was about to touch the ground when Zani showed up, catching him.
"Prince, are you alright? You look tired…" Her face was filled with worry.
Sylus managed to open his eyes, though even then, he could barely see her face.
"Yeah, I'm fine."
Suddenly, the soldier from behind him uttered—
"No way… Y-you built this?"
Sylus didn't have any energy to turn around and check the soldier's expression, but he could tell he was surprised.
Who wouldn't be?
Sylus was barely six years old.
His age still played a huge factor in why he was so exhausted.
After writing that many spells, it was a miracle that he managed to stay awake throughout the day.
"Hey—"
Sylus managed to point at the engine.
There was no time to wait for the soldier's praises, at least not yet.
"Please, connect the mana stone."
