The Extra Prince Sets Out To Conquer The World

About a week after Yekatrice left.

I led my companions to collect the materials from dormant veins and magic ingredients scattered throughout the mountains.

And now I am half-naked, my limbs bound by magic chains.

“Damn it, do I have to do this crap again? I have no choice, do I?”

I was restrained in a 3D magic circle designed by my damned old master, swallowing a rejuvenating elixir of the Sage of the Winter Wood made by Jade.

If I lived an ordinary life, I wouldn’t know, but my mana was too meager to endure the journey ahead.

“Hurry up! Yuan, I’m very excited right now! To see a magic circle woven so beautifully!”

I gave the middle finger to Jade, who was urging me on with his eyes sparkling with the desire to explore.

“Hey, you bastard! Do you know how painful this is to say that?”

Despite my swearing, Jade just shrugged his shoulders and laughed nonchalantly.

“Of course I wouldn’t know. I’ve already completed my mana circuits and am increasing their density.”

“Lucky bastard.”

After drinking together every night for the past week, we somehow started talking to each other without being shy.

It seems we’ve become too mushy, but what does it matter? I’m satisfied to have a drinking buddy.

“I’ll start!”

“Ah, damn it! Aaaargh!”

Jade filled the magic stones and immediately activated the magic circle.

As a result, mana circuits were forcibly developed, causing excruciating pain throughout my body.

“Aaaahhhh-!”

“Ah, it’s a bit noisy. I’ll block the sound.”

“Aaargh! You damn bastard! Is that something you should say?!”

Before even hearing my protest, Jade seemed to have blocked the sound as he was moving his mouth.

“Aaaaargh-!”

Even while I was writhing in pain, Jade was diligently analyzing and recording the phenomena occurring in my body.

After screaming at the top of my lungs in pain from being forcibly opened up all over my body for a long time, I was finally liberated when the magic circle operation ended.

“Ugh…!”

Fortunately, I didn’t faint or anything this time.

“You son of a…!”

Hearing my cursing in a hoarse voice, Jade chuckled and checked my body’s condition.

“Didn’t you ask for help while everyone was busy mining ores, saying you were worried?”

“That’s true, but sometimes you want to blame someone for no reason. And why aren’t you worried about me?”

Jade grinned slyly.

“Hey, how can I not worry about you? Can’t you see me worrying like this right now?”

“I see the face of a mad mage interestingly observing an experimental animal.”

“Hahaha, that’s too much. There’s nothing wrong with your body. If you hold this in your mouth, your throat will stabilize.”

I sucked on the throat candy Jade handed me.

Sweet and bitter. A bittersweet candy, they made something that shouldn’t exist.

“As expected of the Sage’s final research. It has no practicality at all, but such beautiful formulas.”

“It’s very useful to me, you know?”

Grumbling like that, I checked my mana circuits and confirmed how much my mana had increased.

“Almost double.”

Considering the amount and quality of the magic stones used this time, it wouldn’t be strange if it increased at least three times compared to last time, but it barely doubled.

“This doesn’t seem to be very efficient in developing fine circuits. Well, it can’t be helped since it’s a form of guiding the flow of mana with magic formulas.”

At Jade’s analysis, I sighed.

It meant that the major circuits were almost fully developed with this, and it was impossible to become stronger with this improvised method.

In fact, it’s an overstatement to say that one becomes stronger just because the mana container gets bigger.

It just means you can do more things and endure for longer.

Even now, I didn’t feel a lack of mana because I was using magic stones like water.

“It’s just inefficient, but it will be much faster than developing mana circuits on your own.”

“That’s right, because there are spells that block pain. Although it feels like it doesn’t block it at all.”

At my grumbling, Jade chuckled and cleared the magic circle.

This bastard is laughing when I’m feeling complicated?

I put on my clothes and equipped Aquila’s grimoire, Dalanta’s ingredient warehouse, and Yekatrice’s hut in the form of a bracelet.

The hut was a gift Yekatrice gave me before she left, a magic tool that turned the hut she lived in into a subspace, just like Silua’s mansion.

Inside the hut, there were dozens of guest rooms, a freezer, a treasure vault, a magic stone warehouse, and a magic book library.

Most of the important contents, especially Dalanta’s cooking, were taken by Yekatrice, but the hut alone was enough to be called a treasure.

Thanks to that, I put the miscellaneous items that were in the ingredient warehouse into the hut.

Now the ingredient warehouse could only be used for storing ingredients.

I asked her if she could give this to me instead of Jade, but she said it was fine since she had already passed down important things like the magic workshop and magic staff that had been handed down for generations to her disciple.

I think it was a tradition of the Winter Wood not to pass down wealth to disciples, right?

Come to think of it, the Jade in the novel also left the hut as a place of memories.

He took only the core things, saying it was good to start anew, and went on a trip with Precia.

I thought he did that because the memories with his master were painful, but it seemed to have meaning.

While I was lost in thought, Precia, Jade, and Silua finished mining all the ores and arrived from afar.

“I thought I was going to die from exhaustion because monsters kept coming.”

Gilbert exaggerated with a relaxed smile. I countered his exaggeration with a joke.

“If that’s hard, it means you lack training. We need to work him harder, Precia.”

“Yes, understood. I will increase the training amount.”

At Precia’s answer, Gilbert turned pale.

“Ah, no! It’s not hard at all!”

“Then it’s time to move on to the next stage. I’ll increase the training amount.”

Gilbert’s struggle was suppressed too easily.

I patted the shoulder of the dumbfounded Gilbert to comfort him and asked Silua,

“How was it? Did you mine all the places I mentioned?”

“Yes! Diligently! We mined a lot! Right now, due to lack of capacity, we’re storing them in the mansion in their raw gemstone state!”

Looking at it, Silua’s subspace was also no joke.

“Yeah, the cold will blow in again soon.”

Closing the hole to the other world doesn’t mean everything is over.

The monsters spread throughout the mountains also need to be dealt with for everything to end.

It was nearly impossible for Jade alone to clean up this filthy, wide mountain range.

Therefore, it was decided to fix this land in winter for the next 10 years with the power of the Winter Wood Forest, which had been using all its power to maintain the seal.

It’s not an ordinary winter. It was a vicious winter of Bastille where even tough monsters would choose to hibernate.

Monsters that couldn’t eat during the 5-month winter go crazy with hunger.

But if that period lasts for 10 years, most monsters will die while hibernating.

Originally, it should have been done immediately after closing the hole to the other world, but at my request, it was delayed for a week.

It was not only for Precia and Gilbert’s training but also to mine as many magic ingredients and rare metals as possible while we could.

As a bonus, it was also to buy time to inform Demiway that a 10-year winter was coming.

Because if it was too cold, the messenger bird dolls couldn’t fly.

“Now, let’s slowly prepare to depart.”

The destination was the resort city of Ziliville… but there was a place to stop by before going.

*****

“Hmm, this is troublesome.”

I tried to go straight to the sea along the river, but there was no boat.

I searched Yekatrice’s hut warehouse and Silua’s mansion, but there was no boat.

“Is it impossible to make a boat even now?”

Silua shook her head.

There were many blueprints for making magic dolls, but no blueprints for making boats.

Geor was a mage, not a shipbuilder.

“How about riding a golem like we came?”

I shook my head at Silua’s suggestion.

“I used too many magic stones, so I want to save them. It seems difficult to replenish magic stones so easily in other places.”

In the Bastille Mountains, it was fine because monsters were kicking around, but now we had to start saving.

My combat power relying on magic stones would drop endlessly.

Well, it’s fine. I wasn’t a combatant in the first place.

“Ah, aren’t there any amphibious dolls? I thought your father would have made them.”

Dolls also consumed magic stones, but if we rode the water, the consumption would be greatly reduced.

“There are some, but only blueprints and related facilities remain for large and medium ones, and only a few small ones. There were originally few in number, but they were all destroyed when the Kraken went on a rampage before.”

“If we won’t freeze to death while riding, we’ll need a boat. Should we make a raft?”

While I was pondering, Jade said,

“Come to think of it, I heard from my master that my master’s master’s hobby was fishing. There might be something useful if we go to a nearby lake.”

If it’s Yekatrice’s master, that’s at least a hundred years ago, right? I don’t know if it will still be intact.

“Let’s go and see for now.”

Following Jade’s guidance, we headed to the lake where the previous generation’s Sage of the Winter Wood was said to have enjoyed fishing.

The lake we arrived at was so large that it looked like a sea.

“Let’s see, judging by the flow of mana, there should be a warehouse around here.”

Jade, who was feeling the ground, infused mana into the earth.

Then suddenly, a sizable warehouse rose up.

Although it was protected by magic, it was cracked here and there, probably due to the long passage of time without maintenance.

“Ugh, the smell.”

Jade opened the door and ventilated it with magic.

Inside the warehouse, various fishing rods, lures, and rotten fish bait were left abandoned. The smell seemed to come from the rotten bait.

While Gilbert threw away the rotten things into the lake and did a quick cleanup, I scanned the warehouse.

“Are there warehouses like this everywhere?”

“Yes, most of them couldn’t go too far from the mountains until they passed it on to their successors. If we search well, we might discover the legacies of the predecessors.”

Of course, we didn’t have time to go searching for them.

Even if we found them, they would probably be fishing rods or farming tools like this.

“These fishing rods are useful. I should take them.”

Despite being left for a long time, the magic on them kept their elasticity intact.

At least they won’t break while catching fish.

While I was collecting fishing gear, Jade found a boat covered with a tent.

“As expected, there was one.”

The boat Jade found wasn’t very large as it was used by the previous generation’s Sage of the Winter Tree alone.

However, it seemed like it could barely fit five people, perhaps to load fish.

“The wood has rotted a bit, but I think we can ride it at least once, right?”

“At least it’s better than making and riding a raft.”

It seemed a preservation spell was cast on it. Otherwise, it would have completely rotted away like the fish bait Gilbert threw into the lake.

We collected fishing rods, harpoons, fishing nets, ropes, etc., and floated the boat on the lake with Navi’s power.

As my mana increased, I could lift heavy things like a boat alone. Strength is indeed something to cultivate.

“Shall I have Fish-3 pull from the front?”

At Silua’s question, I took out something that looked like a fan from the pantry.

It was one of the things I custom-ordered from the Neslic Company, along with the sniping crossbow.

“It’s fine since we have Rami.”

I didn’t originally intend to use it this way, but as long as it’s used somehow, it’s all good.

Precia made a small hole in the back of the boat. I fixed the fan propeller with a rope so that it would be submerged in water.

Then I got on the boat and had Rami turn the propeller.

The boat then moved quickly as if it had a motor attached.

“Ooh! The boat moves forward without rowing!”

Gilbert exclaimed in admiration and put down the oar he had picked up.

I laughed triumphantly, stood at the bow, and set the direction.

“This is the power of the great spirits! Heading east! The target is the small port city of Akra, where there are boats to Ziliville!”

At my instruction, the small squirrel on my shoulder controlled the waterway, raising its tiny arm along with me.

TN: anytime he mentions Rami, I think of Pachirisu
