The activated rope sports car drove unusually smoothly, and even Erica, who had been on guard all night, took a nap for a while, and Tian seemed to wake up very easily, and woke up once with a fierce squint in his eyes, and Eddie just slept heartlessly.

Even ordinary carriages could not gallop like a rope sports car here, and as soon as the sun tilted a little, they fell.

Candleburg Library.

From a distance, it looks like a huge group of mage towers, lonely and mysterious.

The gate and courtyard below were built in a far-fetched manner, destroying the majesty of the library.

Guarding the gate was a visible giant invisible servant, like a human figure emerging from the air, sitting in the doorway with his head clutched in a daze like a human.

This is probably the first person that the Book Castle needs to visit as the name of the Book Castle spreads throughout the continent, the Gatekeeper of the Book Castle, Gray.

"Mr. Gray, good day" Eddie, the oldest, stepped forward to greet him.

Mr. Gray seemed to be thinking about his own business, and muttered sullenly, in response.

"Mr. Gray, do you like this gift?" Eddie pulled out a glass ball from his backpack that had been prepared long ago, and sealed a crystal clear snowflake inside.

As time passed, Gray, the gatekeeper who had survived with the bookburg to the present day, was tired of his job and began to learn to ask for things from the bookburg, and if he didn't take something new to please him, he wouldn't let you in even if you complied with the rules. The new rules of the Book Castle also spread to the ears of outsiders with the adventurers.

"Do I look like an uninformed bun?" said Gray sullenly, I don't know how much of this uninspiring thing has been collected for so many years.

Eddie sighed, and unfortunately spread his hands to them, and motioned for someone else.

Al took out the building block toys he had made and was given a disgusted look by Gray.

Tian took out a rabbit puppet that looked like he couldn't put it down, and Gray didn't even give Tian a look.

If it weren't for Gray in charge of the outer barrier of the Book Castle, three teams of Carabo war golems who could be summoned with a single password to challenge the level 15 magic immunity golems, and the grumpy Tian might have given it a wave of magic missiles.

Gray didn't know where to conjure a thick cigar, spontaneously combusted without wind, took a deep breath, and exhaled a smoke ring faintly, looking quite lonely.

Seeing that the three of them couldn't even enter the outer gate of the book castle, Al saw Gray smoking and sighing, and suddenly remembered that there seemed to be something that was very suitable for him now.

Using magic tricks, he dug up a piece of soil from the ground, and then separated a dozen parts models with the process of the Mechanical Secret Realm.

"Add, harden them. Eddie didn't know what Al was up to, but he still reached out and used the spell dismantled by the Stone Fist technique to turn the dozen or so parts into stone.

Then Al fused a spare dagger into a spring and assembled a dozen parts, exactly the man's favorite, a pistol with a rough shape.

"Mr. Gray, how is this?"

"Flintlock muskets? I have a lot of this kind of disposable thing, and there are more than a dozen magic weapons that are more elaborate than this. Gray still disliked it, but he took it, guns have a lethal attraction to men, whether he is a real person or a magical servant with a human mind.

"Bang, click" Gray pulled the trigger indifferently, and the rough, wild, crisp excitation caught Gray's attention.

"Bang, click" Gray fired again, the power of the stone gun was secondary, almost nothing, but the sound of the mechanical staggered chamber change triggered Gray's approval and pleasure, and aroused the surging in his heart.

"Bang! click!" "Bang!"

Playing with Gray, the toy stone gun in his hand fragile disintegrates into stones.

"So easy to break?" Gray threw the gravel off his hands, clapping his fuzzy palms in the air, dusting off the dust from them.

"Metal is less perishable, and it sounds better, but we—" Before Al could finish explaining, Gray grabbed it with his hand and threw a large pile of metal ingots of gold, white, silver, and copper in front of Al.

"Make one for me, and I'll let you in, and give you a small gift. ”

The three of them listened to what Gray was saying, and they all drooled as they looked at the metal ingot in front of them.

Magically treated Adamantite, Holy Silver blessed by the High Priests of the Good Camp, Magical Silver Ore and Copper Ore Born from Natural Mines.

Any of these four are prop materials and spell-casting materials that are being scrambled by high-level mages.

"This ...... It's pure ...... Pure magic materials, the texture is too soft, the best material for firearms is steel ......" Al stammered an explanation, his eyes couldn't take these materials off, with these materials, he could experiment with many high-level magic, prematurely experimenting with high-level spells, and from top to bottom, he had a clearer understanding of the spells and principles he mastered.

Gray reached out and grabbed it, and a few more metal ingots came out. Al couldn't recognize it, Eddie only recognized a few, and Thien couldn't hide his desire to occupy it.

"Black Iron in the Dungeon, Stone of Matofil in the Capital of the Dwarven Kingdom, Meteorite Iron Ore"

It's all rare magical metals.

Al's magic tricks are okay to knead the mud, and he can't do anything about these ores.

"Which one to use, you say the size. Gray picked up a piece of black iron, a piece of Matofil's stone, and asked Al, who could not refuse.

"With Matofil, I'll give you the model size. Al took out a few rolls of parchment paper on the spot, and used charcoal to accurately draw out the model and mark the size.

The Stone of Matofil is a raw ingot that uses the unique technology of the dwarves to smelt a variety of ores, and the magic power transmission is extremely good, whether it is to create magic weapons or stimulate magic power, it is extremely powerful, and the hardness of the finished product is close to that of diamonds.

Gray grabbed the drawings and ore and didn't know where to send them, so he took them back with all kinds of made parts in his hands, and the size was exactly the same.

Al spliced the parts together, and drew a drawing of the bullet and handed it to Gray, the bullet is of course a demonized ammunition, and the low-grade gunpowder in this world is of no use.

As for what spells to enchant the bullets, that's Gray's business.

Gray sent away the pile of magic materials that the three Al were eager to eat, and soon came back with all kinds of enchanted bullets.

"It's so luxurious. Those bullets were different, gold and white, silver and copper intertwined, and the magic light flickered, and the three of them drooled when they saw it.

Gray loaded six bullets into it, and one shot at the distance, bang, click. Before anyone could savor the difference in the sound of the guns made of this luxurious material, there was a bang in the distance, and a violent explosion burned into a small mushroom cloud.

Gray laughed heartily.

"Burst fireball!"

The three young mages looked at Gray's guns and bullets with resentment.

How precious the materials that can enchant fifth-level spells should be, this invisible servant is luxuriously used to listen to a sound.
