Hello, is this a letter addressed to Demon Fortress?

After leaving the inn, Lin Gui went directly to the Adventurers' Guild.

Monica was already waiting for him.

The routine treatment began quickly, with hydrotherapy wrapping around my body, the warm sensation seeping into my bones.

A few minutes later, Monica's magic was exhausted, and her face turned even paler.

Lin Gui's injuries have improved somewhat, but he is still far from being fully recovered.

He didn't stay long; after giving the other person a magic recovery potion and thanking them, he left.

Now, he had to get down to business.

There is no post office in Dragonbone City.

The mail delivery service is usually done by posting a transport request directly through the Adventurers' Guild.

Although the price is much lower than that of a real transportation contract, it is still expensive enough for ordinary people.

You need at least ten gold coins to start.

In other words, Lin Gui had virtually no competitors when he opened his post office here.

There's no need to go to the trouble of pulling strings and smoothing things over like you did in Carter's capital.

Now that the nobles and powerful have all fled, the political system of the city-state has almost collapsed, and no one cares what kind of shop he opens.

Lin Gui found a shop for sale in the working-class district in the east of the city.

It's not big, just a two-story stone building.

The price was cheap; I only needed twenty gold coins to buy it.

The location is excellent, right across from the gate of Dragonbone City.

It is the place with the highest population density in the city-state.

In the past, buying this place for twenty gold coins would have been like a dream.

However, the Kuroshio Current is currently surging, and if it moves northward, it will pass through the Broken Bone Pass and enter the tundra.

There is a certain probability that Dragonbone City will be affected.

The noble district and the lord's castle are now deserted.

Almost all the capable, powerful, and wealthy people have fled.

This led to the near collapse of Dragonbone City's economy.

Land prices and housing prices have almost plummeted.

He found several local craftsmen, paid them wages, and had them renovate the site according to his requirements.

The first floor was opened up to create a service hall, with counters against the wall to provide space for queuing.

The second floor is a rest area.

Just hang a sign at the entrance that reads "Seven Copper Coin Post Office, Dragonbone City Branch".

After explaining all this, Lin Gui stopped caring.

He went to the Adventurers' Guild.

Monica had just regained some of her magic and gave him another treatment.

It still takes a few minutes, and the effect is still the same.

But Lin Gui wasn't in a hurry.

After the treatment, he walked to the guild's commission board, took out a piece of paper from his pocket, and stuck it on.

[Publicity Commission: Distribute flyers, reward 100 copper coins.]

There is no agency number and no agency rating.

After all, it's just handing out flyers, something even homeless kids can do.

A new commission was posted, and the novice adventurers looked at it curiously.

When I saw that price.

All the adventurers were excited.

The novice adventurers who had been able to occupy the tables and boast since the high-level adventurers had all fled instantly swarmed over.

"Me! Me! Me!"

"let me!"

"One hundred copper coins per note? That's one hundred silver coins! That's enough for me to eat for half a month!"

Lin Gui even saw members of the Thousand Towers Gang inside.

Ada squeezed to the front, while old Tom held up his shield behind her to prevent her from being trampled. Lily stood on tiptoe to peek inside.

Monica, standing at the very back, smiled sheepishly when she saw Lin Gui looking over.

Lin Gui didn't say anything, but simply handed a bunch of flyers that had been prepared in Karan to the clerk, paid the commission fee, and registered the commission.

After the promotional campaign was completed, he left the guild.

……

Once outside the city, Lin Gui stopped.

Before us lies the Dragonbone Mountains.

Towering into the clouds, the gray-white mountain gleamed coldly in the sunlight.

The mountaintop was hidden in the clouds, and the top was completely invisible.

It is the highest and longest mountain range in the southern part of the continent of Akara.

He is the guardian deity who has protected the borderlands from demonic invasion for thirty years.

It is also the biggest obstacle preventing the border regions from connecting with the central city-state alliance.

Lin Gui looked at it with a complicated expression.

If Karan wants to become stronger, it needs a golden route that can directly connect to the city-state alliance's transportation network.

It needs to be short, but also safe.

He took out a paper map from the storage space and spread it on the floor.

Although the messenger Roth could accurately mark distances and geographical information, it was limited to the places he had traveled.

What you haven't been through is shrouded in mystery.

Therefore, he could only use paper maps to make his judgment.

My finger traces across the map.

Head south from Dragonbone City, cross the Dragonbone Mountains, and enter the frontier.

The nearest city-state is to the southeast, Dragonspine City.

The distance is approximately one hundred kilometers.

An isolated town that was also not included in the city-state alliance.

Two hundred kilometers further south is Huamu City.

One hundred kilometers further south is the city of Karan.

The reason these city-states were not included in the city-state alliance's transport routes is simple: they were small, remote, and had no valuable resources.

Moreover, the Dragon Bone Mountain Range naturally blocked the development of the Gold Route.

At the same time, these isolated city-states are far from the only passable geographical barrier in the Dragonbone Mountains.

This is the well-known golden corridor north of the capital of Carter, the Broken Bone Pass.

The distance is too far.

The Black Tide mages all caused Lin Gui to abandon his plans.

They planned to find a new city-state, like Kalan, that was isolated and whose ruling class had been almost completely wiped out, as the basis for the Spark Revolution.

But the city of Karan survived.

Although Lin Gui didn't know the reason, his original plan could continue.

The first step of the plan is to open up a vital transport route to Karan City.

It's impossible for him to carve a tunnel under this towering mountain range by himself.

He still needs to prepare.

Travel to other city-states and find a way to carve a tunnel under the largest mountain in the south.

His purpose in going there was simply to first investigate the situation of the demons in the surrounding area, and at the same time to find the narrowest part of Dragonbone Mountain.

Within the Adventurers' Guild, adventurers regularly conduct investigations into the surrounding demons.

Lin Gui was able to obtain the information he wanted from there.

But this applies only to the nearest mountains to Dragonbone City.

However, this was not the best section of the mountain he could open up.

So he had to investigate again.

And so, five days passed in this investigation.

During this period, Lin Gui lived almost entirely in the wild.

He only returns to Dragonbone City when he needs treatment.

Monica's treatment was very brief, lasting only a few minutes, before Lin Gui left.

The task of reconnaissance is not simply to record the gathering of demons in the surrounding area.

It is also necessary to record the types of resident demons in the vicinity, the activity range of powerful legendary demons, and the surrounding geographical information.

With the messenger Luo Tu around, Lin Gui was spared a lot of trouble.

But it took him a very long time.

Five days is enough time for an absurdly large number of novice adventurers to distribute thousands of flyers to every corner of Dragonbone City.

People were holding leaflets and talking about it in the streets and alleys, by the pubs, and even in the shacks at the foot of the city walls.

"Have you heard? A new post office has opened at the city gate; sending a letter only costs seven copper coins!"

"Seven copper coins? Are you sure it's not seven gold coins?"

"It's clearly written on the flyer: Seven Copper Coin Post Office, fair and honest to all, young and old."

"Today, many people have seen the newly built post office; the sign reads 'Seven Copper Coins Post Office, Dragonbone City Branch.'"

"Branch offices? Does that mean there are many such post offices?"

"I don't know, I've never heard of it."

"Could this be some kind of trick by nobles to play on us?"

"It's so strange that it opened in Dragonbone City at this time, when the Black Tide was breaking out."

"We'll know tomorrow. They say it'll open tomorrow, so we'll go and see for ourselves."

Most of the residents who received the news were filled with curiosity and eagerly awaited the arrival of the next day.
