Xu Yichen was unprepared for what he would encounter or discover. In the eyes of the Demon Hunter, this was a somewhat adventurous action.

If in reality, he would never enter an underground space that was obviously artificially excavated without knowing nothing about the following situation and without sufficient preparation.

But here, Xu Yichen is a demon hunter, and no one else can complete this kind of task on his behalf.

The most important thing is that he is in a hurry.

Advancing along the narrow underground tunnel, Xu Yichen was far beyond ordinary people's perception and vaguely felt that the tunnel led the two intruders to a deeper underground with an insignificant angle.

What exactly did this tunnel be dug? After walking more than 300 meters below, Xu Yichen determined that with the power of mortals, they could not spend their manpower to build such a channel that is useless to ordinary people.

As the tunnel extended downwards, the height of the tunnel gradually increased, and the demon hunter could walk with his chest raised and his head raised, which made him breathe a sigh of relief.

Before this, Xu Yichen had been thinking about how much combat effectiveness he could exert in the narrow space in the past if he encountered an enemy.

The Demon Hunter guessed that this might be a place where a team of professionals who had once lurked in the town or a group who had specially dug out to hide something.

Because no traps are reserved in the entire tunnel, the holes that occasionally appear in the walls are vents used to keep the air flowing in the tunnel.

Using fingers stained with saliva, you could feel the flow of air. Xu Yichen estimated that he was about fifteen meters underground at this time.

The straight tunnel has no turns, and it should be at the edge of the camp at this time.

A somewhat decaying wooden door appeared in front of the two people.

What exactly is waiting for you?

Did this thing cause the disappearance of the residents who lived here before?

What happened to the person who first dug the tunnel?

At this time, on the ground, the young people standing on the simple city wall were warned. They lit the brazier beside them and shouted loudly: "There is something close outside the city!"

Ted glanced at the heavy armored warrior who was guarding the entrance of the tunnel without any response and said to the one-armed man: "You stay here, I'll go and see what's going on!"

Giving Kasha a wink, the only two professionals left in the camp ran hurriedly towards the wall.

In that direction, the weird roar made the one-armed man feel a little bad, but when he saw Nangong Yujun's tall figure, he relaxed a little.

"If we encounter problems that cannot be solved, you won't sit idly by, right?" the one-armed man asked tentatively. He was not sure what kind of person the other party was.

During the days when he was taking on tasks all over the world, he had seen many professionals, some of whom could be called chivalrous, while others were reluctant to save them. The higher the level of professionals, the more serious they were.

However, players in the Loess Zone have already taken over the burden of fighting chaos or other evils in the hands of the indigenous people, and combat-type players have developed the habit of protecting mortals.

"No tragedy will happen here until I fall." The voice of the black-armored warrior was a little dull when he passed through the helmet, but what he said made the one-armed man feel relieved: "The situation outside is not as bad as you think. If there is really a problem, I will support it in time."

As a player with a profession level of up to 8 and mastering extraordinary power, this small town with a large area is confident that he will arrive at any corner within five seconds.

It may cause a lot of damage to public facilities, but the Black Armored Warrior will not care about such minor issues.

After sending the situation outside to the demon hunter underground, Nangong Yujun focused his attention on the surrounding environment. In the darkness, you will never know whether the exposed enemy is bait.

There may be more dangerous places where there is no sound.

The demon hunter who received the news was slowly pushing open the wooden door. Behind the door, a relatively spacious room of about twenty square meters appeared in front of the two people.

"I can't feel the influence from the void at all." Aifelal said to the Demon Hunter: "Unlike drinking your blood, it seems to be unusually 'clean' here!"

"Clean?" The demon hunter looked around—

A small round table was placed on it with a few books that were no longer visible, a small oil lamp was covered with dust, and an equally dirty chair.

A bookshelves were randomly built on the wall with wooden boards. Now they are broken, and the books that fall to the ground have long been broken.

The most attractive thing is the few boxes piled in the corner, one of which is open, filled with blocks of strips of metal.

Xu Yichen picked up one of the metals, which was much lighter than he thought. Under the dust, it was a silver metallic color, but it was much more shiny than silver.

This is definitely not silver. If you are exposed to air for so long, silver will lose its luster and will easily undergo oxidation reaction with some components in the air.

But after the metal in the hands of the demon hunter was removed from the dust, it was like a sword that had been covered with dust for many years, emitting a silver light.

Mithril!

This is the first word that appears in Xu Yichen's mind. Although he has never seen a metal like mitril silver, after hearing that the pirate king Mama might have mastered a mitril silver vein, he discussed the properties of this metal with the dwarfs Groyin and Carpenter.

For example, it has good conductivity to magic, low density, high strength, etc.

Of course, at the level of the dwarf, the Metasilan metal, I only looked at it from a distance and never fiddled with it myself. It was basically heard from others.

But based on these descriptions alone, Angus Carpenter's eyes were already shining.

"This may be a metal that cannot exist in reality. It has the advantages of countless materials. I can't imagine what this metal will look like." The black guy immersed himself in his world with a blurry look: "If I could study this metal thoroughly, maybe I could try to make it in reality!"

Of course, if Nangong Yujun heard this, he would definitely say: "You are too late, man, we have finished this job."

In Nangong Yujun's experimental armor, this metal was used in large quantities as a conductive material.

It is said that in reality, laboratories have experimentally synthesized this metal.

The scientific officials of New China studied the arrangement order of this metal from the atomic level, and reproduced the one-to-one out of nothing in reality.

This is all thanks to the first group of science officials to enter the game. Many of them have become spell casters of great level. As pure researchers, these people are quite obsessed with spell research.

They optimized the existing spell model and created a spell that can be used to observe microscopic matter in the form of an indigenous people, which allows scientific officials to observe matter more directly.

After two months of discussion, the Anti-intellectual Committee finally determined that this kind of research and development will not have a positive impact on the existence of the void. At the same time, the green skin in the north did not cause corresponding changes.

Eventually the spell was promoted.

And now, in front of the demon hunter, there is a whole box of metal suspected to be Mithril.

Who was the former owner here? Xu Yichen's doubts were even greater.

In front of the Demon Hunter, in addition to this box filled with mysterious metal, there are three boxes that have not been opened.

There were no extra protective measures on both boxes, and they were locked on it with a simple lock. Obviously, the former owner here was very confident in his secret hut and was sure that no one could find it.

So he did not take any unnecessary anti-theft measures.

The Demon Hunter directly pulled off one of the locks and opened the second box.

This box is filled with parchment paper, full of complex formulas and patterns, and the notes look a bit sloppy, but the handwriting is all about the same person.

Xu Yichen picked up a few of them. The parchment paper was thicker than he thought. It was not only very soft, but also extremely tough.

Even though I spent countless years thrown in this unknown underground space, the handwriting on it is still clear.

"This is a paper made from the skin of the bipedal dragon." Efilar picked up one of them, his voice looking a little rushing: "High-level casters sometimes use this material as the material for the magic scroll."

"These are not magic scrolls." Although the Demon Hunter had never used magic scrolls, he had seen them from his teacher, and the spirit-breaking talisman he used before was a type of thing.

Now these in his hands are just some notes, without a trace of magic power.

The value of the magic scroll varies from one hundred gold coins to five thousand gold coins on the market according to the magic level recorded on it.

Higher level magic, ordinary scrolls cannot withstand the power in it, are generally stored in more precious things, such as scrolls made by dragon skins, or gems with perfect structure.

And this valuable paper made of the leather of the two-legged flying dragon is obviously used as ordinary paper to record essays.

"I think these things used to be a powerful spellcaster." The silver-haired witch roughly rummaged through the dragon velvet paper in the box and said to the demon hunter: "Only they have the only ones that store so many precious metals."

"This place is not like a spellcaster's territory." Xu Yichen opened the third box casually: "I thought they all lived in the tower."

The third box contains several sealed glass containers in which unknown biological tissue is soaked.

In one of the jars, there was a fist-sized eye, along with the part of the eye handle behind it.

After being exposed to light, it was swung a few times like a living creature. The whole eye was like a goldfish, changing directions in the container to prevent the light from shining directly on the pupils.

"It's more like someone sneaking into the mage's lab and stealing all these things out." The Demon Hunter gave a more reasonable explanation.

He still remembered Carpenter said that there was a black wizard tower nearby. Maybe someone was thinking about the wealth of the spellcaster decades ago?

Then in an inconspicuous small village nearby, a very secret treasure room was dug without any visible mountains and water.

Then he waited for a suitable opportunity and sneaked into the mage tower and stole enough wealth, such as the things in front of him.

Xu Yichen knew that Yang Yuefan had done this before, but he believed that it was because the mage tower did not have too many alarm measures, and it was entirely to deal with the war.

This also explains why the people in this small village disappeared later.

Since these "stolen goods" have been forgotten here, we can estimate that 80% of the thieves were found to be coming to the door. Perhaps the villagers here have turned into burial objects in the fury of the mage.

However, this inference is too suspicious, and the truth has long been hidden in time. Xu Yichen planned to let him study these documents after there is a spellcaster in the battle group in the future.

In front of him, there was the last box, and the smallest one.

But this box is made of metal, full of patterns that are of no significance, and there is no chain head.

Fortunately, the former owner seemed to have thought about opening this box, which saved Xu Yichen a lot of trouble.

A pried open edge was in a corner of the box. Judging from the traces around it, the previous owner used a lot of methods to open the box, but at the moment before success, he gave up.

Maybe the ‘owner’ happened to come to the door?

Xu Yichen thought so, and inserted his long sword into the gap, and then pried open the box with force.

On the seaside hundreds of kilometers away from this small village, a building suddenly appeared in a huge tower on the edge of a cliff.

A complex machine the size of a truck was originally in a quiet state, as if it was suddenly activated by something, and countless gear levers began to move inside.

With the neat ejaculation, the machine made a roar. A tall figure wearing a black robe, an obsidian mask, and a staff suddenly appeared in the room.

The black-robed mage's face hidden under the mask was invisible, but judging from the frequency of his steps back and forth, he seemed very anxious.

As the machinery moves faster and faster, a carved picture gradually appears in front of the mage.

The three-dimensional photos are like carved with big trees, then swamps, and the ugly evil spirits on them.

Then there was the simple city wall, and the young militia with a nervous expression on it. Then Nangong Yujun's tall figure also appeared in the sculpture, but only half of it had time to carve it, and the machine stopped as if it had suddenly lost its power.

At the same time, in the basement, the Demon Hunter suddenly closed the box.

PS: There is a customer who needs to be received tonight. I thought I could not come back and update it, but I didn’t expect that the company code was finished... PS: Thank you book friend @博活彩彩彩彩彩彩彩彩彩彩彩彩彩彩彩彩彩彩彩彩彩彩彩彩彩彩彩彩彩彩彩彩彩彩彩彩彩彩彩彩彩彩彩彩彩彩彩彩彩彩彩彩彩彩彩彩彩彩彩彩彩彩彩彩彩彩彩�
