Hello, is this a letter addressed to Demon Fortress?

Lin Gui didn't know much about the Bone Heights.

All he knew was that it was a product of necromancy, a forbidden area left behind by the madness that nearly destroyed the City of a Thousand Towers a few years ago.

As for the specific route, the distribution of demons, and the level of danger, he knew nothing about them.

Back in the Deadwood Wasteland, Elvia and Erin mentioned the Ashley family briefly when they talked about it, but only briefly.

So when he arrived at Baiyang Fort, he made a special trip to buy a complete guide to forbidden areas.

He then discovered that the Bone Heights were the least dangerous of all the forbidden areas.

To be precise, it doesn't even meet the standards of a forbidden area.

Those legendary and epic skeletons that once unleashed a frenzy of the undead.

They were wiped out by the mages of the Thousand Towers during that great battle.

The remaining troops were scattered across the barren highlands, posing little threat.

Nowadays, even Gold-ranked adventurers can traverse the Bone Highlands.

The Bone Heights, though a forbidden area.

However, it only has a legendary aspect in name; in reality, the level of danger is very low.

Therefore, Lin Gui had no intention of paying much attention to it.

In fact, Lin Gui had already made this judgment when they were in the Dead Wood Wasteland.

Elvia mentioned that undead frenzy.

The entire highlands were filled with skeletons, yet they still couldn't destroy the Thousand Towers.

In a normal forbidden area, if all forces are mobilized, the sheer number and quality of demons could overwhelm a thousand towers.

Even forbidden areas like the Deadwood Wasteland and the Blackwater Forest, which are considered the worst of the forbidden zones, can achieve this.

As a result, the Thousand Towers were not destroyed on the Bone Heights.

That means this forbidden area is even worse than the bottom of the class.

But it was precisely in this area, which was gradually weakening and whose threat level was continuously decreasing, that the system gave him a necromancy spell.

Even though the magic itself was quite useless and not very effective, Lin Gui's heart was still pounding.

He knows the system's tricks all too well.

Those commissions that didn't explicitly state the dangers always managed to deliver a rude awakening along the way.

On the way to escort Claudia, he was caught by Shadow Blade Lin and almost killed.

What seemed like a simple cargo transport in the Barren Wasteland eventually led to a struggle between half-demons and the Thousand Towers, and even drew out the Great Sage.

The immense pressure he put on himself at the time still haunts him to this day.

Although he only drew a necromancy spell this time, the coincidence made him uneasy.

After leaving the post office and hanging up his letter in the mailbox, Lin Gui began to inquire about information about the Bone Highlands.

Over the next few days, he tried to gather information through various channels.

Books related to forbidden areas published by the Scholars' Guild.

It contains official survey data and risk assessments, making it the most reliable source.

He also chatted with the adventurers in Green Shade Court for a bit.

Find a few seasoned adventurers who have been active in the Bone Highlands.

There are also some local residents who occasionally travel through that area to visit nearby city-states.

His combined roles as transport team leader and post office manager allowed him unimpeded access to intelligence.

Of course, the main reason is that he paid the money.

The information they obtained was almost identical to what Lin Gui knew.

The danger level of Skeleton Hill has decreased year by year.

Unlike ordinary demons, the undead cannot reproduce; if one is lost, the rest of the population is lost.

Legendary mages are also frequently dispatched from the Thousand Towers.

Use powerful, wide-ranging legendary magic to cleanse regularly and prevent the remaining undead from gathering again.

Therefore, the number of skeletons and the dead on the highlands decreased day by day.

Today there is even a trade route that leads directly from the Bone Heights to the Thousand Towers.

Even the Golden Adventurers could pass through it easily.

However, Lin Gui heard many different accounts regarding the cause of that undead frenzy.

The Bone Heights was originally just an ordinary highland, with green hills and trees, not much different from the surrounding hills.

Until a genius dark mage from the Ashley family.

The former master of the Dark Tower conducted a forbidden experiment there, which subsequently triggered a horde of undead.

The crux of the controversy lies in where those skeletons came from.

Adventurers who personally experienced that frenzy said that skeletons almost covered the protective barrier erected by the Thousand Towers.

The mountain was covered with skeleton monsters emitting ghostly flames, layer upon layer, stretching as far as the eye could see.

There are also several enormous skeletal beasts, each capable of crushing the city walls with a single step.

So many skeletons couldn't have appeared out of thin air.

Even summoning magic creates alchemical creatures by recombining metal-based magical elements, rather than actually conjuring them from the void.

Some say that the mage, in order to take revenge on the Thousand Towers, collected a large number of powerful demon corpses in advance, extracted their skeletons, and buried them underground in the highlands.

Some say that he activated a forbidden magic array, connecting with the underworld and awakening the sleeping souls of the dead, thus triggering the disaster.

Some even speculate that he was backed by demons, who helped him accomplish this natural disaster.

Some even suspect that an undiscovered underground city lies hidden beneath the highlands, a lost ancient ruin.

There are different opinions.

The only thing that can be said for sure is that it was impossible for that mage to create such an exaggerated commotion on his own.

As for the official explanation...

That matter has always been a taboo subject, and no one knows the real reason.

The more Lin Gui understood, the stranger his expression became.

As for the recent situation at Bone Heights, the information he received was very clear.

There were no abnormalities.

Lin Gui put down the intelligence in his hand and rubbed his temples.

The situation at Bone Heights was pretty much as he knew.

The number of undead has decreased year by year, and the threat has continued to decline. Even the Golden Adventurer Group can pass through, and there is even a trade route that leads directly to the Thousand Towers.

There were no abnormalities.

He almost began to doubt whether he was being overly sensitive.

Just then, the branch president of the Green Court Transport Association came over.

He was a slightly overweight middle-aged man with a perfectly measured smile on his face.

He was slightly bent over, and his tone was as respectful as if he were receiving a distinguished guest.

"Lord Lin Gui, is there anything else I can help you with?"

Lin Gui remained silent for a moment.

He wanted to ask a few more questions about the Bone Heights, but he swallowed the words back.

We've asked everything we needed to ask and investigated everything we needed to investigate. Asking any further won't yield any new information.

"I need to....."

He paused for a moment.

"Information on the latest transport convoy stop in Spirit Taming Valley."

The branch president's expression stiffened slightly, and a hint of confusion flashed in his eyes.

"Sir, didn't I already give you one three days ago?"

Lin Gui didn't answer, he just looked at him.

Those black eyes were as calm as a deep pool of water.

The branch president felt a chill run down his spine from being stared at, quickly lowered his head, turned around, and hurried back behind his desk.

He searched for a while, then quickly ran back with a list in his hand, handing it to him with both hands.

"These are all the recent records, sir."

Lin Gui took the list and unfolded it.

His gaze swept quickly across the train convoy's name and the dates of its stop, his finger moving down the entries.

Then he stopped.

In the lower middle of the list, a line of text caught his eye.

【Star Car Team - Arrival Time: May 10 - Estimated Stay: Three Days】

Lin Gui's gaze lingered on that line of text for a moment.

From White Poplar Fortress to Greenwood Court, he kept a close eye on intelligence regarding the transport convoys from Spirit Taming Valley.

That transit city-state in the north was a necessary stop on the route for many transport caravans heading to Thousand Towers.

Back in Deadwood, when Raymond tried to win him over, he mentioned their route.

Spirit Taming Valley is the last stop.

Their transport route runs regularly between Deadwood Town and Thousand Towers.

He only needs to look at their records of stay and departure times over the years to estimate their approximate arrival time.

Now, the list says May 10th.

Today is October 11th.

After confirming the team information, he folded the list and put it in his pocket.

Thank you for your trouble.
