In the face of Xu Nan's interrogation, Rafal knew everything and said everything.

This guy is very self-conscious, and many times he learns to answer before Xu Nan asks.

Seeing his excessive desire to survive, Xu Nan felt a little funny.

If all this is not a performance, then this guy is really the best among treasure hunters.

Typical silly white is not sweet......

The information given by Rafal is not much different from Xu Nan's estimate. There aren't many treasure hunters in the Northlands, but there are quite a few of them who can pose a threat to Quelrath or even himself.

Most high-level professionals don't specialize in treasure hunters, so they don't have as much information as specialized treasure hunters, so it's no wonder Quiras doesn't take these people seriously.

To put it mildly, they are contenders for the Frost Giant's Treasure; To put it mildly, they just followed and picked up some leaks in the back.

It is worth being wary of the other group of people mentioned by Rafal.

According to Rafal, they were joined by a group of wanderers who were not treasure hunters. Most likely, they're from the Ninth Manor, and they're under the command of Green Light!

Even the green light himself may be involved in this adventure, after all, the tomb is not the Ice Wind Leader of the main material world, and the legendary wanderer really took action, and there will be no neighborhood committee staff such as the Cloud Climbing Monk to maintain the stability of the community.

In fact, Xu Nan has always been very curious about the true purpose of the green light, and he has also asked Qin Lele to pay more attention, but unfortunately Qin Lele's connections in the Ninth Manor are not very good, and he is still in a state of blackness.

However, it is certain that the green light must have something to ask for, and its purpose should be similar to that of the blood orange, otherwise the latter would not identify the green light as an enemy; And what Blood Orange asked Qin Lele to do was to follow Geralt from beginning to end.

"Geralt ......"

Come to think of it, this ordinary middle-aged priest is not extraordinary, but a series of signs indicate that he is the protagonist of this tomb expedition!

"Qin Lele and Geralt must be found as soon as possible!"

Xu Nan made up her mind. Before leaving, Gray had come to him, hoping that Xu Nan could take care of Geralt within his ability. At that time, Xu Nan rarely laughed at Gray, but Gray did not fight back.

Xu Nan asked Gray why he was so interested in Geralt, and Gray himself couldn't say why, but he just felt that Geralt was a good person, and this kind of good person shouldn't just die.

This may be a reason, but it is definitely not the fundamental factor that supports Gray to do so.

Xu Nan's curiosity about Geralt is also growing day by day.

"Let's hope he's still with Quelas."

Xu Nan stood up and gently recited a spell to untie the magic rope on Rafal's body.

Rafal clutched his lower body and stood up in pain, twenty minutes had passed, and the traces left on his body by Xu Nan's Tyrannosaurus Fist were still reminding him of the terrifying fighting ability of the spellcaster in front of him.

"Lead the way."

"Find the lab area."

Xu Nan gave the order.

He is not afraid of Rafal running away, this guy has obviously been frightened by himself, coupled with the shadow of the Tyrannosaurus fist method, with Rafal's mentality, he can't afford to disobey himself at all.

Rafal didn't squeak, endured the pain, and began to grope around.

Soon, he found a sign and some other markings, and determined that their location was indeed the underground area of the Arcane Institute.

It's a seating area, so the architecture is very ordinary, and there's nothing special about it.

Xu Nan breathed a sigh of relief.

It seems that the divine storm did not blow itself away, but was directly sent to the underground of the island.

Quelas made it clear that the Arcane Empire Research Institute is on a small island with multiple levels of underground space, and only through the Institute can the Frost Giant's crypt be found.

And the entrance to the Frost Giant's Tomb is in the experimental area.

Under Xu Nan's deterrence, Rafal worked hard to play the family tradition of treasure hunters, and soon locked the direction, and the two did not delay and began to move forward quickly.

Xu Nan thought about it, and took out the magic carpet to travel, not because he was lazy, but because the magic carpet came from Stephen Sand, and he was inextricably linked to the Arcane Empire, and if he encountered any intelligent units, he might be able to identify friendly troops.

Although Paradise Lost is also an ally of the Arcane Empire, after all, he has a history of betrayal back then, and Xu Nan doesn't believe that every intelligent unit of the Arcane Empire can be received by him as smoothly as Flowing Fire.

It took them about ten minutes to leave the rest area, then walked up a spiral staircase, and three minutes later reached a deeper level underground.

Here, the terrain becomes more open, and the height of the space has changed from seven or eight meters to a full ten meters high.

At the exit of the spiral staircase, there is an open square, and the big black guys in the square are covered with thick magic canvas, and I don't know what kind of guy is hiding inside.

Not far away, a robotic arm lay on the ground, along with a gemstone that had lost its luster.

There was no ash on the ground, indicating that the Arcane Empire's constant cleansing spell was still working.

The square runs east and west, and the road on both sides is not clear at the end.

This has to do with the relative darkness of the space, where the light source of the lighting equipment is limited, and dark vision is not omnipotent.

"This is the equipment area."

"According to a map of the suspected research institute that I got at a high price, the equipment area should be next to the experimental area, but I don't know the specific direction."

Rafal put away the map in his hand and looked at Xu Nan with some apprehension.

He knew very well that now his life was in the hands of the man in front of him.

If there is any experience that the treasure hunter who has failed for so many years can provide him, it is that he must not be able to meet a strong person, he must kneel when he should kneel, and living is the most important thing.

Xu Nanjing walked out.

Lined with dark buildings and magic canvases. There seems to be a slight reflection ahead.

In the Psychic Vision, there was no reaction in the vicinity, which meant that there were basically no people.

"Let's take a look."

The two walked over and found that those reflective ones were actually rows of constructs!

These structures are all created from a mold, very similar to human cavalry, and the mechanical arm on the ground just now is estimated to be an accessory for this kind of structure.

Xu Nan leaned closer and confirmed the code name of this thing.

Sentry.

Sentinel build body? Xu Nan's heart moved.

The so-called constructor is another name for the magic construct. It is essentially an alchemical product and occupies a very important position in the history of alchemy.

Strictly speaking, the inflatable puppet made by Xu Nan at the earliest time can also be regarded as the most rudimentary structure, but it does not have too high intelligence.

The Construct was not the first of its kind in the Arcane Empire, but the alchemy of the Construct was carried forward in the Arcane Empire. In that protracted war with the gods, the Arcane Empire's constructs army also achieved very impressive results.

This kind of robot in the magical world made of magical metal with different effects has had a very brilliant development and achievements in the history of the Arcane Empire - but unfortunately, the Arcane Empire fell before the construction technology was at its peak.

In today's Universal World, constructs are often found in the ruins of mage towers from the Arcane Empire era, and are rarely made by modern mages - not that constructs have been eliminated, in fact, a smart constructor is fully capable of the position of mage's apprentice or assistant, and the traditionally indifferent spellcasters are often more inclined to make their own magical constructs than to train disciples.

And the constraint on this is the material.

After the fall of the Arcane Empire, the third type of metal almost disappeared from the main material realm, and after the most important core ingredient of magic construction was taken away, the construction technology also fell rapidly.

Today, with the exception of Stephen Sand, who still has a few structures in service, most of them are in a state of remnants and rehabilitation. Most of them were excavated from the ruins and restored to a certain extent under the hands of alchemists before they could barely be restored to their original appearance.

A complete construct is almost impossible to find in the Northland.

But now, more than thirty-six complete structures are placed in front of Xu Nan.

Xu Nan glanced at Rafal and muttered, "What is your dream?" ”

Rafal subconsciously straightened his back: "Become the most powerful treasure hunter!" ”

"What do you think of these constructs?"

He asked.

Rafal thought for a moment: "It doesn't seem very practical......"

"Okay, let's stop talking, go check if there are any traps and traps."

Xu Nan didn't listen to him and continued, this guy is definitely no play!

Rafal was a little confused, and ran over to check it with a little grievance.

And Xu Nan, taking advantage of Rafal's inspection, quickly opened the Paradise Lost system and inquired about the information of the construct called the [Sentinel] series.

He was pleasantly surprised by the results, and the internal database gave high praise to the construction of the Sentinel series -

[The Sentinel series has super anti-magic capabilities and melee skills that are not inferior to those of fourth-order warriors, and its loaded intelligent modules can be competent for combat missions in various environments......]

[Sentinel 1~17: The purpose of the first generation of sentinels is to complete the security tasks of research institutions, so this generation of sentinels has strong detection capabilities and anti-stealth unit capabilities, and on the premise of ensuring basic magic immunity, the first generation of sentinels is loaded with the melee mode of twenty-nine quasi-legendary classes and the coping strategies of all classes......]

[Sentinel 18~24: The second-generation Sentinel has both escort effects and is suitable for water combat......]

[Sentinel 25~37: The third-generation Sentinel has added a landing battle module, officially advanced from a security structure to a military structure, and its weapon module has been strengthened by three times, with lightning spiders and magic energy tanks, it has extremely powerful landing combat performance......]

The research reports are as if they are reading papers, blowing up the sky.

Xu Nan took a look and found that the Sentinel series was a technology that Paradise Lost was very eager to get from the Arcane Empire. However, due to the fact that the third type of metal was firmly controlled by the Arcane Empire, even if it was obtained, there was no possibility of mass production, so it was finally abandoned.

But that doesn't prevent Paradise Lost from lemons for the sentinels.

This thing has developed from the beginning of the security structure to the last military structure, and the specific history has been recorded by Paradise Lost.

"These thirty-six sentinels belong to the third generation of sentinels, and the model should be Sentinel 35, which belongs to a more mature model."

"Rafal said that this is the institute's equipment warehouse, even if it is an equipment warehouse, why put so many military-grade constructs?"

"Could it be that Quellath is mistaken, this is not a research institute at all, but a real military camp?"

Xu Nan's guess is not too outrageous.

Sentinels are a core secret of the Arcane Empire, and should only be found in barracks. Judging from the situation near the square, the Arcane Empire retreated in a rather hasty manner, so the structures were not disposed of.

They all seem to have turned into clunky lumps of iron because they have lost energy, and the specific control method requires the corresponding key. Xu Nan doesn't know how to get the key for the time being, but let's get the constructor back first.

Those guys in Paradise Lost, there will definitely be a way.

It's really not good, and the person who sold it to Stephen Sand is also a not too bad processing channel, but this is the next step for Xu Nan.

He is now in a critical period of power development, and a special forces composed of powerful constructs is simply a tiger to him, especially in the context of the sudden assassination of the old king, it is estimated that it can come in handy.

Rafal's examination is actually quite simple, that is, to test it with the flesh - a few punches at the sentry, and if there is no response, there is no immediate danger; Then I checked the other details, there were no traps, no traps.

Xu Nan estimated that even if there were, it would be weathered.

This research institute was much older than he had estimated, and if it weren't for the constant [Extremely Slow Time Flow] spell of the construct itself, he might have encountered a pile of scrap metal now.

"Take!"

After Rafal's physical examination was confirmed.

Xu Nan happily opened the dimensional pocket and began to stuff the structure into it.

Thanks to the large space in his dimensional pocket, it would have been very difficult to move these sentinels.

Rafal saw Xu Nan taking things out of thin air, and he was even more frightened, and he didn't even dare to take a second look.

It didn't take long for this equivalent to three squads of Sentinel 35 to be emptied by Xu Nan.

"Go around here and see if there's anything like it."

Xu Nan commanded.

Rafal got the order and immediately went to run errands.

He had carefully checked the neighborhood himself, but unfortunately the rest of the space was occupied by the big black guys, except for the platform that housed the sentry.

There was a strong smell of seals on the magic canvas, which was a warning left by the Arcane Empire, and Xu Nan was a little warlock who didn't dare to try to crack it.

Even if he was very curious about what was under these canvases, he was just curious.

The two searched for a while, and after no result, they decided to move east, which is actually a handful, after all, there is no basis for judgment.

They had been walking for about ten minutes when there was a sudden movement in front of them.

Someone is running for their lives! And it's several.

The airflow began to get confused.

In the depths of the darkness, there was a faint sound of strange beasts roaring and neighing.

Not long after, several figures of embarrassment and escape appeared in front of their eyes, and there was a huge long black shadow!

Like a snake!

Rafal wanted to run without saying a word, but at this time, Xu Nan suddenly noticed in his afterglow that a large magic canvas next to him had actually been torn off!

A cold cannon barrel turned straight and straight for ninety times, aiming directly at Xu Nan and Rafal's heads!

Beneath the canvas is a cold and monstrous war machine!

At that moment, Xu Nan's hairs stood on end!

He saw the whole picture of the big man: thick tracks with an eerie magical sheen, cold shells symbolizing indestructibility, and loaded weapon modules that were enough to make ordinary people shudder!

"Arcane Empire's Magic Tank?" He subconsciously wanted to dodge, and in the next second, the barrel of the cannon turned thirty degrees again, aiming at those who fled in a hurry!

Xu Nan was a little uneasy. Is there anyone in this tank? How many thousand years has this thing been left open?

He wanted to retreat and see how it went.

Who knew that at this time, the small window of the tank was suddenly opened, and a small face was revealed:

"Xu Nan! Give it a go! The monster is coming! ”

Xu Nan was stunned for a moment, and his first reaction was to ask the other party: "How did you get in?" ”

Qin Lele blinked:

"I don't know, press F......"

Xu Nan was speechless, he knew that Qin Lele would not be far away from her, but he didn't expect to see her on the magic energy tank!

Soon, he deduced that Qin Lele was probably the same as him, and was directly sent to the tank by the Divine Storm, which is normal, the Divine Storm has the ability to tear through space, can stuff him from the lake to the rest area, and can also stuff Qin Lele directly into the tank.

He realized that the monster Qin Lele was talking about was the menacing strange snake, so he pulled Rafal away.

One of the few humans who were running accidentally stumbled and fell, and was swallowed directly by the giant snake, without even having time to let out a scream.

But his death gave his companions a chance to survive, and the rest fled to both sides.

On the main road, only a cold cannon barrel remained, aimed at the strange snake.

Rumble!

A cannon rang out.

The entire underground research institute trembled violently!
