Dwarf Gorren, Halfling Romi, and Jerry from the town.

The dwarf's power is powerful, which makes him very stable when carving in woodworking. As long as he can calm down and carve slowly, it is still easy to complete the course.

Halflings have very skillful hands and have natural advantages in carpentry. If it weren't for the fact that the carving materials were extremely hard iron wood, he would probably have completed the course long ago.

Jerry is the son of Tracy, a carpenter in the town, who originally knew how to work in the woodworking process. It was just because Green had extremely high requirements for accuracy that he did not complete the course until now.

Looking at the wooden boards handed over by the three of them, Green observed carefully: "Gorun. Your place is cracked, and there is an extra piece here..." Green handed the dwarf's board to the dwarf, "This magic circle has been scrapped. You can keep it for practice."

The dwarf took the board back dejectedly.

"Since two apprentices have completed their courses, today's course will be changed to internships." Greenton paused, "Everyone comes with me, and the internship class is held in the workshop."

Green brought his apprentices to the Magic Workshop.

The Magic Workshop is not far from the apprentice dormitory and is expanded from the previous workshop.

I found a workbench and Green fixed the board to the workbench.

"Ironwood is very hard, lightweight, and has good magic resistance performance. It is the best material for making warships and airships, and it can also be used to make magic arrays. Not only ironwood, but any hard and good magic resistance performance can be used as the base of magic arrays. So the question is, in addition to ironwood, what other materials are suitable for making magic arrays? Guolun."

"Stones, and various metals other than mitesilver!" the dwarf replied excitedly.

"What you said is too large. The base of the magic array requires high magic resistance performance, but it cannot use materials with the effect of "exorcism". For example, cold iron and pure gold, while they have magic resistance performance, they will also reject the surrounding magic power, which will disrupt the operation of magic power. Therefore, materials that have high magic resistance, but cannot exorcism can be used as base materials. Ironwood and obsidian are the most common base materials. In addition, ordinary stone slabs are often used on certain disposable magic arrays."

Green took out a box of mitesils.

"This is a thin filament made of Mithril, which has good magical performance." Green took out the Mithril silk in the box and showed the students, "Anything with good magical performance can be used to make magic props, but Mithril is the favorite of magicians. Does anyone know the reason?"

Green asked the apprentices.

An apprentice raised his hand.

"Tom." Green named.

"Because Mitsunian not only has good magic performance, but also is also very strong, heat-resistant, cold-resistant and corrosion-resistant."

"The answer is perfect. Mithril not only has good magic performance, but also has good stability. It not only has excellent performance, but also very durable. Therefore, Mithril will be used when making advanced magic items."

After Green gave some simple explanations to the apprentices, he began to "solder the circuit board".

Magic is ultimately an energy.

If magic is described as "electricity", then the magic array is a "circuit board" composed of conductive "wires" and insulated "insulating boards". The lowest-level "circuit board" has only one layer, and only "wires" and "insulating boards". Advanced circuit boards have two or even several layers. In addition to "wires" and "insulating boards", many small "electronic components" will be installed on it.

Green carefully inlaid the mitril silk into the magic circle. Since the magic circle had been carved, Green just needed to inlaid the thread.

After inlaiding the "wires", Green took out some small magic powers he had prepared from another box, and embedded them into the reserved slots. These magic crystals are not only batteries on the circuit board, but also small electronic components on the circuit board.

The work process is boring.

The "circuit board" of [Spirit Constant Spelling Mirror] is not too complicated, but it is definitely not simple. Fortunately, the most time-consuming part of the work has been completed by the apprentices, so three hours later, Green finally completed all the inlay work.

"Ha~ I'm finally done." Green twisted his neck, "The next step is the last step."

Put a magic mirror on the magic circle, then chant a spell and cast a spell!

"Spirit Constant Send Mirror!"

Compared with many preparations in the early stage, this last step seems much simpler and faster.

Accompanied by the brilliance of magic, the wires and magic crystals on the entire wooden board began to shine and operate. At the same time, a faint layer of light appeared on the surface of the magic array, and some lines and directions could be vaguely seen. Afterwards, an image appeared in the mirror placed on the circuit board...

"Yeah~ It's successful." Looking at the image in the mirror, Green smiled with satisfaction.

Around them, a group of apprentices stretched their necks and looked into the mirror. A hint of curiosity appeared on each of them.

Green waved to the apprentice beside him: "Jerry, come here and try the magic props you made yourself."

"Okay, OK, mentor." Jerry hurriedly walked forward.

Jerry looked carefully at the mirror in front of him: "What appears in this mirror is..." Jerry suddenly raised his head and looked at another mirror on the workbench, "Is the image in that mirror appearing?"

"The answer is correct." Green nodded with a smile and picked up another mirror on the table. "This is a sending mirror. The two mirrors will display the images in the other mirror respectively."

Green took the mirror in his hand and changed the angle. At the same time, the picture in the picture in the other mirror also changed.

Looking at the mirror in Green's hand, all the apprentices couldn't help but get excited and chattered.

"Okay. The experiment ends here." Green motioned Jerry to go down.

Jerry stepped back obediently with excitement on his face.

Green walked forward and pointed his finger at the magic mirror: "Cancel the magic!"

"Bee~" and the image in the mirror disappeared.

Green picked up the lesson plan and noted Jerry's grades and credits on it.

"Jerry and Romi received ten credits, which is a gold coin reward." Green took out two gold coins and handed them to Jerry and Romi.

Taking the gold coins from Green, the two apprentices had excited smiles on their faces, which were so easy to come by than going outside to fight to the death!

"Jerry, Romi, you two have completed the first topic. Next, you can obtain funds by engraving the magic circle. As a magician, funds are very important! In addition, I have just demonstrated the inlay of the magic circle for you. Next time you can try inlay after completing the engraving."

Hearing Green's words, the two apprentices couldn't help but lit up!

"Don't be too happy too early." Greenton paused, "The reward for inlay is also a gold coin. Although it is not easy to scrap the materials when inlay, if any material is scrapped, the fine is enough to make your reward waste! If any magic crystal is broken... you should slowly repay the debt by carving the magic circle!"

Hearing Green's words, the expressions of the two apprentices became entangled in an instant.
Chapter completed!
