"This ruin, I really like to surprise me. Nishizawa withdrew his mental power and sneered.

The previous time the metal door suddenly opened, he already felt that something was wrong.

Now a door appeared silently on the wall.

Isn't this a human mentality?

Could it be that someone opened the door from inside the ruins?

Thinking about it so carefully, Nishizawa was stunned.

Someone opened the door to the ruins right under his nose, then he must have seen the development of the Great Tomb from beginning to end.

He definitely also learned all about the Great Tomb.

The most important point is Nishizawa's ability to fuse three undead spirits out of thin air, as well as the so-called "holy relics" that appear out of thin air.

Nishizawa dared to guarantee that this kind of inexplicable power could not be possessed even by the imperial class.

Otherwise, it is absolutely impossible for Daddy Dead to fall in the Abyss War.

So Nishizawa thinks it's impossible.

Ruling out this most terrible thought, the Undead Monarch let out a sigh of relief.

It would be terrifying if all of his efforts so far had ended up in the eyes of a voyeur who hadn't had the slightest interest in Nishizawa's abilities.

The problem, then, lies in the ruins themselves.

Which country and which race left this metal door relic?

Nishizawa felt the need to make a trip himself.

"Celia, call the decapitator, take your flesh stitch monster with you, and we'll go to the Metal Gate Ruins. Nishizawa commanded.

The Dark Princess nodded obediently.

"Wait......" Nishizawa muttered for a moment, "Call Master again, maybe he'll be needed." ”

Moments later, Nishizawa led a small group of guards to the ruins of the metal gate, accompanied by a bewildered-looking blacksmith.

He didn't know what the Supreme Master wanted to do when he pulled him out of the smelting work.

There used to be a small iron ore mine on the ground of the ruins of the metal gate, but now all of them have been mined, but the number of undead left here is second only to Castle Black.

It is because of the existence of the remains of the metal door.

Because he knows very little about the worldview and power of this world, Nishizawa has no idea what civilization left this relic behind.

For example, Nishizawa still doesn't know what the connection between Hell and the Abyss is and this world.

Coming to the remains of the metal door again, and looking at the huge heavy metal door that was open, Nishizawa felt the rough, direct, and unaesthetic architectural style again.

The overall style of this relic is four words, pragmatism.

Instead of engaging in those virtual and beautiful things, anything only needs to meet its own function.

The Undead Monarch suddenly thought of the books he had found earlier in the ruins.

Most of them are related to smelting and metals.

"Could it be the remnants of a dwarf?" Nishizawa thought of a race that could call themselves the kings of smelting.

"No, the remains left by the dwarves, why did they build the door so high?" Glancing at the metal door dozens of meters high, Nishizawa directly overturned this idea.

Then they came to a new door in the huge room.

As expected, this door is also like the giant door outside, without any artistic creations such as patterns and patterns.

The only modification that has been done is probably to polish the surface of the metal door very smooth.

The height and width of the metal door inside are also smaller than those outside, only about 10 meters high and 5 meters wide.

Nishizawa mentally named the giant gate on the outside as "Gate No. 1", and the door on the inside as "Gate No. 2" to make it easier to distinguish them.

Without Nishizawa's order, the beheader took a few steps forward and propped his hands on the second door, exerting his strength to push the door open.

And yet it didn't move.

Celia empathetically gave the flesh a hint of pushing the door.

And so the stitching monster, powered by the power of the deep darkness and composed of flesh and blood, stepped forward in a dull manner.

It stood to the right of the decapitator, with the same hands propped up on door number two, faithfully fulfilling the task given by its master.

Squeak.

The two powerful undead used all their strength to make a gap in the second door.

Next, the door opens naturally.

When it first opened, the interior was still swarthy.

But as Nishizawa caught his eye in it, the lights inside lit up from near and far.

After Nishizawa led the undead in, the scene made him smack.

The word "chaos" can be used to sum up the internal situation.

It's an equally huge room.

The floors, walls, and ceilings are also unknown metal castings.

It's hard and heavy, but it doesn't transmit mana very well.

The floor of the room was littered with scattered metal objects.

Propellers, screws, pistons, bearings, rivets, gears......

Their characteristics, without exception, are particularly huge!

On top of that, there are all sorts of broken metal pieces that seem to have undergone a violent attack.

But all of these things have a very similar thing in common - they all have scorched marks.

When Nishizawa saw these things, he was honestly a little blindsided.

Machine?

I always thought it was a high demon world.

Think about it, undead, subhuman, sorcerers...... This is not what else can be in the High Magic World.

At this time, Master suddenly exclaimed, "God, what kind of smelting process is this?"

The chief blacksmith of the Great Sepulchre rushed to the largest piece of metal and rubbed the section of it with his finger bones.

"Lord Supreme, the dwarven smelting is completely unable to make such a metal piece, but this metal is tougher than anything I've ever seen. ”

Celia also whispered, "Supreme Lord, I feel that there seem to be traces of high-level spell splashing on the surface of those metal sheets. ”

Nishizawa pondered, but did not speak.

He noticed the key point in the girl's speech.

The surface of the metal sheet shows traces of high-level spell sputtering.

This shows that the so-called high-level spells do not attach special properties to the metal sheet like enchantment and infusion, but directly act on the metal surface.

Most likely, it was an attack.

This proves why there are traces of blackening on the surface of these metals.

The Undead Monarch has a guess for the time being—it's most likely a high-level fire-based spell.

"Lord Supreme, can you allow me to take some metal pieces for research? I dare to conclude that this novel smelting technique combined with the Dwarven smelting technique will definitely achieve a huge technological leap!" Master excitedly.

"Of course," the Undead Monarch responded, "I want you to do that too, the Great Sepulpin needs your smelting skills. ”

"Master will definitely live up to the Supreme Lord's entrustment!" Masters looked excited, holding the metal plate.

He looked at these metallic eyes, almost like he was looking at a great beauty.

Turning around the room again, just as Nishizawa confirmed that there was nothing of value, the Dark Princess exclaimed, "Lord Supreme, here's a booklet, and some broken bones. ”
