Lord Vincent excused himself for a lack of materials and did not compete directly.

But the big words have already been spoken, even the demons can't break their promises in public, right?

The result of offending the Mage Guild is not something that he, a little lord, can bear.

"We'll see." Safin was also tired enough, so he asked the apprentice to move a chair for him, sat down in a big way, and said, "Demons are always unpredictable, I hope you can bring us some surprises." ”

Anyway, as long as the lord of this demon clan doesn't run away, defeat is only a matter of time.

In addition, he was already very sure that although this young man was a royal family, his magical attainments might not be high.

Spells can't be said to be no, but there will definitely not be many, and they can't beat themselves at all.

Go back to the castle to get something, does he have any magic weapons from the demon world?

Since he is the son of the Demon King, it makes sense that he has one or two excellent weapons.

Thinking of this, Safin couldn't help but be a little worried, if the lord brought those forbidden demon weapons from the big war, how would he end up.

Fortunately, those weapons that destroy the country and slaughter the city can only be controlled by those with strong magical power, and this immature lord is afraid that he will not dare to touch it, right?

The more calm Vincent became, the more the Great Magician beat the drum in his heart.

The answer was soon revealed, and a young girl with blonde hair tied up in a blue ribbon, a white shirt and a blue high-waisted skirt, led the lord's men into the venue.

This contrast seemed to the magicians and apprentices to be a stark contrast between angels and demons.

The blonde girl is Ninia Wald, who has recently made a name for herself in the city, leading a group of slow-moving skeletons to carry an item covered in cloth on a large flatbed cart.

"Master, the crystal has been delivered." Ninia saluted Vincent respectfully, "The crystal is too big, so it's been delayed. ”

"My toy, you're doing a great job." Vincent complimented, "It's time to show the real technology." ”

Magic crystals? Safin's ears pricked up in his head, and he squinted at the items that Vincennes' men had brought.

Under the tarpaulin, there are crystals.

It's not common to see such a large crystal, but no matter how you look at it, it's just a large piece of ordinary clear crystal.

The crystals sparkle in the sunlight, and from the side, the prismatic section is larger than a tavern table.

Twenty skeletal soldiers struggled to place the crystal on the ground, and they fetched some more wood.

"This crystal is real." Vincent stroked the crystal clear surface and sighed, "It seems that Level 1 is not enough. ”

"Hello, System."

"Ding!"

"Show my boosts."

[Bonus Value: 5870/5899]

The maximum amount of protection seems to have increased, and Vincent judged that he still had enough protection to splurge on.

It seems that the skills unlocked before need to be upgraded.

"System, I want to upgrade my optical instrument manufacturing and processing skills."

"Roger. Are you sure you want to upgrade your Optical Instrument Machining Skills with 500 Bonus Points? ”

"Sure."

"Ding! Your 'Optical Instrument Processing Skill' has been upgraded to Lv2 and has 5370 Bonus Points remaining. ”

The current skill level may still not be enough to complete the high-precision toys you want......

"Upgrade to lv5!" Vincent didn't hesitate to order the system, "I'm going to do the whole thing this time." ”

"Each level of technology upgrades, an additional 100 points of protection value are consumed, and upgrading to lv5 requires a total of 1800 protection points, are you sure you want to upgrade the technology to lv5?"

"Confirm."

[Boost: 3570/5899]

Next, Vincent, who consumed nearly half of his protection value to upgrade his skills, quickly opened the eyes of the people on the scene.

Under Vincent's hands, the huge crystal was first sliced whole.

The lord chose from several slices, and finally selected the most ideal slice for processing.

Irregularly shaped crystal slices are processed into squares.

Next, Vincent began grinding the flat crystal sheets, processing their surface into a slightly raised, sleek shape.

This is actually the method of processing glass lenses, but unfortunately in the world where Vincent is currently living, glass has not yet been produced.

In fact, even if it was placed in his previous life, it was not an easy task.

Crystal and glass may seem very similar in appearance, but they are actually two very different substances.

Since crystal is a crystalline of silica and glass is a molten mixture containing silica, crystal has hardness that surpasses that of glass, as well as better thermal conductivity and light projection.

High-quality natural crystal is not like glass, and there are no bubbles or water ripples caused by process problems, so the price is not cheap.

Of course, glass also has the advantage that it can be produced in large quantities, and it can also be melted and reversed.

Lacking skills and materials, Vincent can't rub the glass by hand for the time being, but he doesn't lack the crystals that are abundant in the Demon Realm.

Ninia stood beside Vincent, her lake-blue eyes staring curiously at the familiar figure.

The sparkling and graceful crystal changed its appearance in his hand, and the girl's eyes gradually began to have a hint of admiration.

The lord's beautiful long fingers rotated methodically on the protruding mirror surface of the crystal.

From the outside to the inside, a circle of equidistant concentric circles is depicted, like a ring of ripples in the lake, constantly rippling outward.

The precise and calm gesture of the lord, as if he is an artist creating a masterpiece, is truly pleasing to the eye.

Even the magicians who represent the advanced productive forces in this era can't help but be surprised in their hearts.

This craft is more magical than magic!

Compared to this kind of smooth processing, making that adjustable angle wood frame is not a big fuss.

After the lenses and frames were made, Vincent, with the help of his men, carefully installed the crystal lenses and frames, and made some simple adjustments to confirm that his production met the design standards.

"Ding! This production consumes 200 points of protection value, and the god has sensed the ingenuity, and gives a special reward to increase the upper limit of protection value by 100 points! ”

[Boost: 3370/6199]

"I love God!"

Vincent couldn't help but be ecstatic in his heart, this is the upper limit of giving away for nothing without the need for believers!

With more protection, more and more complex toys can be made.

With the sharp weapon of hand rubbing, Vincent is also about to start his own performance.

"Be careful not to stand in front of my lenses." Vinson warned, "That's extremely dangerous. ”

Ninia handed the prince a handkerchief, Vincent wiped his sweat, looked up at the dazzling sun after the afternoon, and smiled very sunny.

"The sea sails by the helmsman, and everything grows by the sun. Sun, give me the strength to live! ”

Rays of sunlight shine through the wonderful lenses, instantly converging into a triangular prismatic light visible to the naked eye, and the light spots at the tips fall on the broken iron box several meters away.

No one expected that a jaw-dropping scene would appear a moment later.

On the surface of the heavy iron plate, some small debris began to splash out, and the entire outside of the irradiated spot turned red-hot.

Safin, who had studied magic all his life, looked at this shocking sight, and his old eyes, which were usually not wide-eyed, widened.

The iron plate was burned through by the light!

How hot is this light, which can burn through the iron sheet that can't even be burned?

If it was an armored warrior, what would be the miserable fate now?

"Is this light magic?" Safin stammered, "But it's not magic...... Is this the Magic Mirror? ”

"Let me reiterate that my fire magic is taught by the Ice Demon, which is very unreliable." Vincent walked into the old man and said in a high spirit, "This is the Fresnel lens, not the magic mirror." ”

"Fresnel lenses? Is that what you're talking about...... Technology? ”

"Yes, it is to turn the weak into the strong. The strong get happy technology. ”
