The unknown machine hidden behind the magic mirror is rectangular, about calf height, with a round lens-like glass product on the front. In terms of appearance, it does look a bit like a shoulder-mounted camera.

Taking a closer look with the light technique, you can see that it is placed sideways on a narrow track. It should have the function of moving forward and backward, and there is also a rotatable handle embedded on one side.

It was precisely because he looked closer that Pei Renli turned his eyes slightly and saw that there seemed to be some patterns that looked like words on the edge of the frame.

Originally, it was covered with a thick layer of dust. Maybe it was the dust that was shaken off when the magic mirror was smashed, and that's when people noticed it.

He knocked it with the staff (wooden stick) in his hand to shake off more dust. He found that the parts that looked like words and decorative patterns were cleverly blended together. If you didn't look carefully, you would definitely miss it easily.

past.

After careful identification, Pei Renli determined that the text on the edge of the frame was magic text.

Magic text is magic text. Its pronunciation is generally relatively simple, such as ko, ha, ne. It does not have the ability to transmit information and communication, and is a purely instrumental text. It is usually used to make scrolls and enchant magic.

On items and spells used to cast spells.

Frowning, he carefully searched his memory and the rules of magic words, then turned around and looked at other mirrors in the room.

It's not a magic mirror, and there are no magic words on the frame.

After comprehensive consideration, Pei Renli felt that the magic text above was not a spell, but something similar to a word puzzle or prompt, reminding those who knew the answer to stand in front of this magic mirror and cast a certain spell.

As for what the answer is and what a certain spell is, we don't know. It should be a code passed down by word of mouth.

But the answer is not important, after all, they have smashed all the mirrors.

The advantage of knowing this clue is that you can roughly confirm that this unknown machine is not a fatal mechanism or a trap, otherwise there will be no mess of prompts.

After confirming this, Pei Renli asked the others to spread out, drew a simple symbol himself, and spread his fingers far away:

"Hand of the Mage."

A translucent stance palm was immediately created by the power of magic, and floated behind the magic mirror under Pei Renli's control.

Mage's hand is similar to the light spell. They are both the lowest level tricks. They can create a magic hand to help pick up things, but they cannot pick up things that are too heavy.

The first lesson that adventurers learn in school is that it is best not to get started with things you don't know directly, especially things related to magic, so let the mage do it for you.

Controlling the position, the palm of the hand grasps the crank handle on the side of the machine. Since there is a certain delay in the control of the mage's hand, it is somewhat troublesome.

After confirming that the grip is secure, use it to turn the handle.

As the crank rotates, the machine hidden behind the magic mirror moves forward on the track little by little. After two crisp clicks, it may have reached the predetermined slot and cannot continue to rotate and move forward.

As he advanced a little further from inside, Pei Renli leaned over and saw a gem-like object inlaid on the top of the machine.

Use the mage's hand to open the lattice on one side, and the gem will move slightly, which means it is released from the slot.

After picking it up, he discovered that the appearance of this gem looked a bit like a diamond, but it was indeed light blue. He held it up with a mage's hand and illuminated it under the light spell. Pei Renli saw three flashing runes inside.

It suddenly dawned on him that this should be an artificial gemstone.

Gemstones are often used in making magic items, but not just any gem will do, nor can you always find gems that meet the requirements.

After all, whether you can dig natural things mainly depends on luck, while artificial gemstones can be customized. The disadvantage is that it requires advanced technology and a lot of funds, and the cost of artificial gemstones is sometimes more expensive than natural ones.

But when it comes to selling these things, it’s hard to get a good price. After all, they are all specialized for a certain purpose, and few people buy them.

The three runes inside the gem are 'illumination', 'change' and 'turn'.

This is not a rune needed to activate a spell, it should be some kind of spell effect.

Thinking of this, he stuffed the gem back and closed the latches again, motioning for everyone to stand aside, while he stretched out a finger to press on the gem, and slowly injected some magic power.

The reason why the detection magic didn't sweep it out is because it doesn't have magic power. In this case, Pei Renli can act as an energy source.

With the injection of magic power, the gem glowed dimly, and the 'lens' placed at the front of the machine lit up, shooting out a flashlight-like beam that happened to fall on the opposite mirror.

But the light beam that was supposed to be reflected back suddenly turned thirty degrees, turned red in color, and shot toward another mirror.

After several bends, the light beam is connected to every mirror in the room, and the color of the light beam in each mirror is different. If you look at it from directly above, you will find that the light beam forms an irregular and asymmetrical polygon, like

It's some kind of emblem.

However, no one was interested in looking at these details, because at the same time as the beam appeared, the rough sound of stones sliding could be heard on the floor in the center of the room. Where there was not even a crack, it was like a door panel that opened upward, revealing a square

At the entrance of the cave, with a quick glance, you can see that there is a staircase inside.

Pei Renli did not explain. The three people present did not know the details. In their opinion, Pei Renli easily opened a secret passage with this operation, and they all showed their words like they had seen Alton debunk the trap before.

I can't understand it, but I'm shocked.

Sure enough, professional things must be done by professional people.

After the injection of magic power stopped, the light beam disappeared, but the opened secret passage was not closed. The four people leaned over and looked around, and could only see a pitch black, and an unusually cold air coming from the pavement below the secret passage...

–‐‐——–‐‐——

It is normal for there to be secret passages under the school. There are too many legal and illegal magic researches under there. Moreover, due to the dispute between the person in charge and various forces in the country, even if it is a research institute established by the same country, they do not know what is hidden there.

How many secrets.

The problem is that the extremely cold air that people feel when they get close is like someone blowing cold wind on the back of your neck.

This is a very obvious sign of excessive negative energy.

It is easy to accumulate negative energy underground, and this stuff is harmful to any living creature. As far as body sense is concerned, it shouldn't have much impact as long as it doesn't stay there for a long time.

This was one of the reasons why the teacher warned them not to go below the fifth floor. Not to mention whether they could defeat the monsters on the lower floors, the environment alone would make these students who were unprotected and not strong enough die inside.

Everyone still walked down the stairs in standard formation, and after going about ten meters deep, they finally saw the ground.

The magic lamp arranged on the ceiling above the head sensed someone approaching and tried to activate it, but perhaps due to its age and disrepair, it only flickered twice before being completely suppressed. Now the lighting can only rely on Peri Renli and Feng Dahl's light spell.

The warm aperture sweeps away the darkness and refracts large, weird and elongated shadows when it encounters objects.

Gary held up his shield and looked around and said:

"This seems to be a warehouse? Are those parts for something?"

Coming down from the stairs, everyone seemed to be in the middle of rows of neat shelves. There were a large number of metal parts on the shelves, and there were no labels, just stacked on them casually.

"It looks like it's a magic alloy, not an ordinary metal. Don't touch it."

Vondar is a dwarf, and dwarves are naturally the best at forging and are very keen on metals.

Pei Renli stood at the end of the team. He attached the light ball of the light spell to his staff and raised the staff high to make the aperture wider.

The expanded lighting swept out things that were originally in shadow and darkness and were different from the shelves. It looked like... a drawing board?

Everyone took a closer look and found that it really looked like the stand of a large drawing board. The difference was that a thick stack of paper was held in place of the drawing board.

It is a square with a length of about one meter. The paper has a blue background and a large number of black graphics and text on it.

Alton raised his neck and glanced up and down:

"I think this thing looks like a blueprint, but I can't understand what's written on it. It shouldn't be in common language, right?"

"Elvish."

Pei Renli identified:

"This should be a drawing of some kind of golem."

Since alchemy was originally an invention of the elves, some alchemists still use Elvish on their drawings today, just like doctors who write prescriptions in Latin.

"Is it really a blueprint? Is it valuable?"

"This shouldn't be worth anything. It's just a simple assembly drawing. Unless you can find the supporting technical details, it's of little use."

The assembly drawings are equivalent to the instructions for assembling the toys. There is no value in taking them out alone. After all, there will be no technical details in the instructions.

"Golem, can you assemble one? I see there are a lot of parts nearby."

Pei Renli spread his hands:

"Not to mention whether there are enough parts, the densely packed pipelines and parts marked on the drawings are enough to give me a headache, and I might not be able to install them all by myself even if I have to do it for a month."

Strictly speaking, the golems in the school library are also golems, but they are cheap castrated products, equivalent to mini versions of youth.

The combat effectiveness is not as good as the golem, and the cost is not as expensive as the golem. Moreover, because the golem is more flexible, there is a certain market.

Both the golem and the castrated version of the golem are high-priced items, but it is impossible to assemble one, which also disappointed everyone's expectations.

"Don't be disappointed yet. Since there are blueprints and parts nearby, it should be a workshop for assembling the golem. Maybe you can find the alchemy core, which is the truly valuable thing."

"What does the alchemical core look like?"

"Most of them are cubes, with a large number of magic words and magic circles on the surface. Usually the colors of the lines are gold, silver and bronze. I have seen an alchemy core sold for a high price of 1,300 gold coins before."

"One thousand and three!"

After hearing this, the three people's hearts were filled with excitement. Although none of them were as short of money as Pei Renli, no one thought they had too much money.

However, what Pei Renli said was very true. The alchemy core he knew was quite special, and it only fetched a high price at an auction. Normal alchemy cores would not be that expensive.

Of course, it's definitely not cheap.

The alchemical core is the most important component of all alchemical creatures. It can provide energy and allow alchemical creatures to have artificial souls that can understand commands. Depending on the material and power of the core, the price is between 70 and 400 gold coins, even if it is second-hand

The depreciation price will not be reduced much.
