Dark area, Royal City of Audus.

From the moment Brian stepped out of the teleportation array, hot air and pungent air rushed towards him.

He saw the forged red hot steel and more than a dozen non-stop furnaces supplying iron materials continuously, and a group of gray dwarves were knocking and beating in the room.

"Gods, what did you bring me here for?"

After adapting to the dizziness brought by the long-distance teleportation spell, the moon elf mage Ru Yin looked at the clanging hammering and slugging mechanical sounds that kept echoing in the factory. She said with a pale face, "This...is this a city of gray dwarfs, right?"

"That's right."

Brian nodded slightly, looked at the new Deep Earth King Erdy who was walking towards her in the distance, and said to her, "Don't worry, these gray dwarves are all my allies. The purpose of coming here is to check the products I customized here and what progress I have reached."

"The Grey Dwarf is... your ally?"

The moon elf mage looked at a group of bald dwarfs with gloomy expressions in disbelief and walked over with a smile on her face when she saw Brian. She secretly breathed a sigh of relief, but couldn't help but feel curious, and asked, "Are you customized weapons and equipment?"

She was a little confused about what the other party wanted to invite her here.

"No, you'll know later." Brian did not say it directly, but met the King of Deep Earth who was walking over.

"His Excellency Brian, I didn't expect you to be back so soon. Is the journey on the surface still going smoothly?" The King of Deep Earth welcomed his arrival like a bearded relative. He shook hands with Brian and said enthusiastically, "Let's go! Let's drink a few drinks first."

"I'm not here to drink with you." Brian interrupted him with a slightly serious hand, "How are the items I need?"

"It was developed successfully yesterday, and I'm waiting for you to come and inspect it myself." The King of Deep Di smiled and said with a smile, "Let's go, come with me."

Knowing the character of this half-elf on the surface, he stopped talking nonsense and immediately took Brian and the other two through a wide corridor and came to a small room.

Brian saw an old gray dwarf man in a dirty grey robe and glasses inside, holding a magnifying glass and studying in a small pinch of metal dust.

"This is the old patriarch of the Salosga clan who has retired for nearly a hundred years and belongs to the most authoritative master of metal synthetic materials in our clan."

The young Deep King touched his thick beard and said proudly, "The piece of ferrous metal you gave me was analyzed by this master."

Brian looked moved and walked over immediately.

The old gray dwarf raised his eyelids and looked at the Deep Earth King, nodding slightly to greet him.

Then he got up and took out a black wooden box from the counter behind, raised his stiff head, looked at Brian, and said to him:

"It turns out that this ferrous metal was sent by you. You have to admit that I have been studying metal materials for more than 400 years and have never seen such an unknown item. Although I can analyze the material for making this metal and even restore it, the mysterious runes polished on the surface of the metal are forbidden to be incompetent and cannot be deciphered at all."

"Otherwise, I might be able to really make the same product." The old man from the gray dwarf said with a regretful look, "What a pity, you can clearly feel that there is a mysterious power hidden in this piece of black metal, but it just cannot be copied."

"You've done a great job, Master." Brian complimented and opened the black wooden box in front of him.

In fact, if the ferrous metal in the old man's mouth is called by the scientific name, it should be called stone.

This black stone was a small piece he smashed from the black pentagonal spire in the Royal City of Audus. The purpose was to ask them to help analyze the materials for the stone.

As the other party said, there is indeed a mysterious power hidden inside this black stone.

He had seen the broken spire with his own eyes, and naturally he knew that the source of mysterious power was the obscure runes polished on the surface of the spire.

Although he still cannot decipher the secrets of runes with the secret knowledge he has mastered now, it is still possible to help him analyze the production materials.

After all, even if these black stones do not have the power brought by the blessing of mysterious runes, their hardness and magical conductivity are very outstanding.

While he was interested in the characteristics of the stone itself, he also considered that if one day he really grasped the secret of the color-resistant scroll, he might be able to decipher the secret of the black five-sided minaret.

Because he suspected that the minaret was likely a mysterious Weaver organization that built a portal system when he tried to colonize the world of Torrell.

He no longer thought about it, looked at the opened wooden box and saw that it was not a finished product, but a pile of staggered production materials.

This was what he specifically asked the King of Deep Earth to do, asking them to only restore the synthetic materials of this stone and not make exactly the same items.

He saw that in addition to the largest number of metal-compatible potions of the Obsidian and Grey Dwarfs, there were also a small number of various gems, fine gold and mitril powders, as well as crystals and similar precipitates, and even a few unfamiliar materials that he could not even name.

"It seems that you have seen it too."

The old man from Gray Dwarf said, "These materials are all related to magic, and when they are integrated with each other, not only improve the hardness, but also the magic conductivity is very significantly improved."

Brian nodded slightly, expressing his agreement with his statement.

Of course he knew this, and it was because he was attracted by the characteristics of these stones that he chose to conduct in-depth research on it.

——"Psychic power is a magical craft!"

Brian stopped talking, he focused on looking at the raw materials, and his mind moved.

Driven by the spiritual creation system.

All these materials floated in the air, and under the control of his mind, they were completely decomposed and all gathered together, and finally shaped into a black stone brick similar to a brick-shaped one.

This chapter is not over, please click on the next page to continue reading! Bryan waved his hand, and this heavy stone fell into his hand.

Stone bricks (unnamed)

Special materials

Type: Stone

characteristic:

1. Physical effect: The number of physical impact points per inch thickness is 25.

2. Magic effect: This stone has excellent adaptability to magic energy and has a 15% damage reduction for any magic attack.

Note: This is a processed using rare natural quartz, magma, dragon crystal precipitate (obsidian) and steel mixed substances, with good physical strike resistance and excellent magic conduction characteristics.

…………

After checking the attributes, Brian tried to inject an arcane energy.

A faint magical aura flashed, and a little bit of aura emitted from the dark stone bricks, revealing his smiling face and reflecting on the smooth surface.

Seeing this, he immediately realized that while the black stone brick injected energy, it also absorbed additional magic energy from the air.

This means that when he engraves a magic circle or constant magic on this stone brick, he can obtain additional buffs.

"The effect is good." He nodded with satisfaction, placed it on the table, and said to the King of Deep Di, "If you make a stone brick of this specification, how many gold coins will it cost."

He is very satisfied with the product. If the cost is too high, he will not be able to promote it.

This is like the reason why gold and silver are obviously very conductive, but when using wires on a large scale, they promote copper wires.

The King of Deep Earth put the stone brick in his hand and weighed it. Then he looked at the old man with gray dwarf. After thinking for a moment, he quoted him a price, "300 gold coins per piece."

300 gold coins?

Hearing this number, Brian raised his eyebrows.

Although he is not a professional, when he first checked the raw materials, he noticed that the material with the most ingredient is obsidian.

Obsidian originates from volcanoes. It is a natural glazed glass formed by the sudden cooling of the magma flowing out of volcanic lava. It is an amorphous gem.

It is not only the most tyrant caster in the wizard group, but also the necessary things for building altars for the priests of the gods, especially the evil gods and priests.

In the surface world, the price of a thumb-sized obsidian block is around 10 gold coins.

As for the underground world, which is rich in obsidian, the price will be relatively low.

Brian can only see from the proportion of obsidian materials that the price the Deep Earth King of the Royal City of Audus was quite conscientious.

"I accept this price." He nodded slightly, pondered for a moment, and said, "If I need ten thousand stones of this specification, how long will it take for you to complete it."

"Ten thousand yuan?!"

Hearing the number reported by Brian, the Deep King Erdy exclaimed, widened his eyes and asked in disbelief, "Stones are on them, I said, what do you want so many black stones for?"

"You are planning to build a wizard tower, are you?" Moon Elf Mage Ru Yin's light blue eyes flashed, and she expressed her guess in surprise.

"Yes, I really plan to use this material to build a wizard tower." Brian said truthfully without hiding it.

This is a plan he decided before returning to the surface.

The Wizard Tower is also divided into three or sixty-nine levels.

The materials for making the primary wizard tower are generally made of marble or granite from nature, and then enchanted and strengthened by the owner of the tower in the later stage, as well as various guardian barriers and traps are arranged.

The challenge level of the owners of this wizard tower will be increased by about 3 levels when they stay at the wizard tower.

The materials for making intermediate wizard towers are similar to those of primary wizard towers. The most significant difference is whether they have tower spirits.

Because the Wizard Tower with Tower Spirit is like a manually driven car. Upgraded for autonomous driving, the effect is naturally very significant.

For wizards with this kind of wizard tower, they can completely complete most of the operations of the tower by tower spirits, and their challenge level will be increased by about 6 levels.

The so-called advanced wizard tower completely distances itself from the intermediate and primary levels.

The materials for making towers are no longer natural processing products from nature, but special building materials carefully refined by alchemists through various metal materials.

Such a wizard tower is strong enough to resist the Nine-ring spells even if the protective barrier or the mysterious lock array is not opened, the strength of the tower itself is enough to resist the Nine-ring spells.

In the city of Arabia in the Kingdom of Cormier, the wizard tower that has been passed down for thousands of years in the wizard tower where the female grand duke Mycella Raul lives is a high-level wizard tower.

Brian once witnessed Arab City being ridden by the floating city of the Ghost Empire, and when the tower's energy protection field was broken, he still resisted at least 5 Nine-ring spell meteor explosion and stood firm.

For tower masters living in the Advanced Wizard Tower, their challenge level will be increased by at least 10 levels.

If it weren't for the deterrent power brought by this high-level wizard tower, it would be impossible for the female grand duke who only reached the initial legend in Arab City to defend the northern border of the kingdom for so many years.

As for the so-called legendary wizard towers, although Brian has never seen them show their true power with his own eyes.

But he at least knew that the most significant difference between the legendary wizard tower and the advanced wizard tower was actually whether he had the ability to fly and cross-plane combat.

In the small world where Brian was reborn, there is a legendary wizard tower from the Kingdom of Harua.

Unfortunately, when he got the tower, he realized that the tower's owner was dead and the tower spirit was completely asleep.

For him, this was no different from getting a car with less keys, so he could only stare at him.

Although the floating city during the Naserel era also had the maneuverability of cross-plane flight.

But their floating city, from Bryan's perspective, is more like a movable city than a so-called fortress of war.
