[Snow Dragon's Horn].

That's right, it's the material item he got when he opened the treasure chest just now.

Although Luo Jie was not sure that this was the key to unlocking the treasure land, the one that best matched the three descriptions of "cold, stout, and hard" in the code words at the moment was undoubtedly this white dragon horn.

Of course, if Namachina was a male dragon, maybe he would consider turning around and digging a grave to try something else.

He took out the dragon horn and inserted the transparent tip of ice deep into the hole in the wall, only to hear the rattling of the machine spring inside, and the originally smooth mirror wall slowly slid to the sides.

What appeared in front of me was a pitch-black tunnel leading to nowhere.

Luo Jie tried to take a step forward.

As if touching some kind of mechanism, the lights continued to light up one after another, extending into the interior of the tunnel.

Lamp?

Luo Jie looked at the silver-gray steel tunnel in front of him in surprise, the obviously sci-fi-style walls and lighting, completely incompatible with the alien fantasy style of "SAO" fantasy world.

[You have discovered the "Mysterious Ancient Ruins", in this fantasy realm, the technology creation and thermal weapon are disabled, and they have been unlocked. 】

Seeing this line of system prompts popping up from the visual projection, Luo Jie couldn't help but be stunned.

Actually unlocked the tech weapon ban?

Then this also means that this so-called "mysterious ancient ruins" should be a technological creation different from the SAO main world.

Enemies soon appeared in the passage ahead.

It was a group of tin can robots that were slightly taller than normal humans, mottled with red rust and a very steampunk appearance, heavy and clumsy.

Although the thick barrel of the gun could be seen on the body, due to its age, the ammunition stored inside had become ineffective, and it could only be attacked with fists in both arms.

For these purely mechanical monsters, the [Seven Fat Cuts] of [Ming Knife Puffer Poison] cannot take effect, and the once invincible attack is suddenly halved.

Luo Jie had no choice but to take back his customary [Ming Knife Puffer Fish Poison] and take out the [Style Knife Shura Ghost Queen] as a hole card.

"Huh?"

At this time, he unexpectedly discovered that the level of [Shidao Shura Ghost Queen] was no longer the original LV.1, but became LV.2.

"Bloody Nirvana" - Raise your level by killing powerful creatures, if you kill creatures with special bloodlines, you will have a chance to gain additional attributes or special skills.

Obviously, this level should have been upgraded when he killed "White Dragon Queen" Magina before.

Seeing that there were more and more robots in the tunnel ahead, Luo Jie didn't have time to take a closer look at the attributes added by the upgrade of [Style Knife Shura Ghost Queen], so he did not hesitate to turn on the "Sacred Thunder Light", and dragged out a bright arc of electricity with both knives in his hands to meet him head-on.

The description of "Sanctuary Thunder" is "doubles the damage of evil targets", but Thunderbolt has the ability to restrain technological mechanical creations themselves.

In the constantly flickering thunder, these old robots that were cut to the ground with missing arms and legs fell to the ground one after another in black smoke, and none of them were Luo Jie's enemies.

There's no way, the attribute restraint is too powerful, if these robots have intelligence, it is estimated that they will be scolded on the spot MMP.

However, the number of these rusty iron cans was so large that Luo Jie had to chop them for a while and then fled outside to regain his strength.

Fortunately, these robots seem to strictly follow the procedure, rigidly guarding this tunnel, even if the door is open, they will never step outside half a step, which gives Luo Jie time to calmly use "death reforge".

This tug-of-war lasted for three whole days, and just when Luo Jie began to wonder if there was a robot repair factory in the depths of the tunnel, there were finally no new robots.

At the end of the tunnel is a huge machine factory that looks like a steel mill and crisscrossed the pipes.

Seeing the faintly glowing ice lake above his head, Luo Jie realized that he had come to the interior of the Holy Dragon Snow Mountain.

"Here...... What exactly is the place? ”

Luo Jie looked at this huge factory that could be called a miracle in shock, and the only thing that could give him a little hint was the word "YoRHa" that could be seen from time to time in his field of vision.

And then the eggs.

"Forget it."

Luo Jie shook his head, the illusion system is so urine, maybe it will give you something to come in somewhere, even those senior explorers don't dare to pat their chests and say that they can know the origin of every messy scene.

Since this is a treasure hiding place, it is natural that the search for treasures should be prioritized.

The function of this huge factory before the shutdown seemed to be the kind of Android-like defensive robot that looked like it was before production, and when Luo Jie was searching for treasures, he found a lot of robot parts that had not yet been assembled, and the number was as high as tens of thousands.

For this kind of relic, which is obviously beyond the technological level of the main world, Luo Jie almost instantly made up more than five versions of the story.

Of course, it doesn't make any sense, it's just a boring brainstorm.

It's really boring, and it's extremely depressing.

The sound of footsteps on the iron plate echoed in the empty mountains hundreds of meters high, and it felt as if the whole world was left alone.

If it weren't for the despair of suffocating and lonely buried deep underground, Luo Jie would have been driven crazy by this lifeless mechanical cemetery.

After searching the factory for nearly five days, Luo Jie finally found a row of strange iron cans on the top platform near the bottom of the glacial lake.

Most of these cans have been opened, and many damaged robots are placed inside.

These robots are not the mass-produced tin cans of the factory below, but extremely intricately crafted humanoid robots, which are completely indistinguishable from the appearance of ordinary humans if not for the exposed mechanical structures.

It's a pity that it's all bad.

However, Luo Jie soon found an extremely well-sealed iron can in the row of iron cans.

He suddenly had a very strong premonition.

The treasure that he had been searching for days should be in this tin can.

With intuition, Luo Jie pressed the most obvious green button on the tin can, and the iron lid above slowly slid open, driven by the small amount of residual backup power supply.

A female robot in a black dress with short pale blonde hair lies quietly in it as if she were asleep.
