Ao refers to a mysterious, unknown, profound and difficult-to-understand meaning, while Shu refers to skills and techniques.

Arcana refers to skills and techniques that are obscure, mysterious, unknown, profound and difficult to understand.

Arcane magic was originally in the hands of wizards, priests, or some pharmacists who liked to use extraordinary means to treat patients in the form of occult science. The specific age of its emergence cannot be verified.

However, looking back from the establishment of every major theory of arcane science, we can find that an obvious watershed was the 107th year of Bingyuan. Cicero, the arcane master of the Kingdom of Tarde, founded the "Treatise on Arcana", marking the official advancement of arcana.

Become an independent academic discipline and enter the public eye.

Jiangxi Lin looked at the "General Outline of Arcane Science" in his hand. Now he can basically read it independently without the use of auxiliary tools.

Arcane science is a subject that extremely requires divine power and talent. According to the introduction in the book "General Outline of Arcane Science", the effectiveness of an arcane spell mainly depends on the same frequency of fluctuations in mental power and arcane space.

State, the more consistent the two frequencies are and the higher the similarity, the better the effect of the arcane spell will be.

Therefore, the "training" of arcanists is almost all based on meditation. Through meditation, they sense the fluctuation frequency of the arcane space and adjust the fluctuation frequency of their own mental power to make it consistent with the arcane space as much as possible.

The spells and spell materials only help regulate the fluctuations of mental power and make the arcane spells more effective.

For a true arcane master, there is no need to arrange spells or recite complicated incantations. Powerful arcane spells are just at their fingertips.

After Jiang Xilin read the book for a while, he sat cross-legged on the sofa and started today's meditation practice based on the meditation method introduced in the book.

After taking a few abdominal breaths, the whole person calmed down. He felt as if a beam of light was shining on his body and his whole body was warm, so Jiang Xilin began to officially enter the meditative state.

First, a tiny star point appeared in the darkness. The star point was like a breathing lamp, flickering rhythmically.

Jiang Xilin took the initiative to adjust his breathing so that his breathing could follow the rhythm of the twinkling stars.

When the frequencies of the two were completely consistent, the second star point appeared.

Jiang Xilin slightly adjusted his breathing rhythm, and at the same time worked hard to control the twinkling of the two star points.

This operation was repeated countless times, until Jiangxi Lin felt extremely strenuous, and then he realized that there was already a sparse starry sky in his consciousness.

After gritting his teeth and forcing the two star points to synchronize again, Jiang Xilin gave up continuing to synchronize and began to stabilize the flickering frequency of this sparse starry sky.

…

…

It snowed all night.

Jiangxi Lin had breakfast early in the morning, then put on his thick coat and hat and went out into the wind and snow.

I didn't sleep all night again last night, but fortunately, meditation can also slightly relieve the fatigue caused by not sleeping.

To sum it up, the dark circles under his eyes, bah, the smoky eye makeup will not get any darker.

Today he planned to pick up the kitchen utensils customized yesterday and continue to deepen his contact with the blacksmith.

As usual, there were not many pedestrians on the street.

The city's snow plowing team swept the snow from the streets to both sides of the road, and then the steam locomotive sucked it into the large cargo box on top of it.

Jiang Xilin hurriedly passed by the snow clearing team and walked towards the area where the tall water tower stood.

The blacksmith's shop was visible in the distance. A strong man in a black vest held a pitch-black hammer and struck hard against a piece of red-hot metal on the anvil. Sweat flew out and sparks flew everywhere.

"Hey boss, are my kitchen utensils ready?"

Jiang Xilin patted his cheek, which was stiff from the cold, and asked in a lively tone as he approached.

The man who was concentrating on blacksmithing looked up at him, then pointed in a direction with his right hand holding the hammer, his voice was low and thick,

"Where is it? In addition to yesterday's deposit of ten copper buckles, you can just give me ten more copper buckles."

Jiangxi Lin did not give the money immediately, but walked to the counter to inspect the goods.

There were only three pieces of kitchen utensils he bought, a wok for cooking, a frying pan for making pancakes, and a pseudo-pressure cooker with tenon buckles.

He checked over and over again for a long time, neither saying it was OK nor saying it was not possible, until the blacksmith couldn't stand it anymore, put down the hammer, and walked to Jiang Xilin.

"Have you finished reading?"

Jiang Xilin then raised his head, looked at the oppressive strong man next to him, and grinned,

"Well, it's very good. I'm very satisfied."

"Then give me the money."

Jiang Xilin smiled and took out ten copper buttons from his pocket, handed them over and then quickly continued,

"Boss, I have another thing with a more complicated structure. I wonder if you can make it."

"Haha, boy, do you know who I am? Craftsman Laird, I'm not bragging. There is nothing within the scope of your knowledge that I can't create."

What a joke, what kind of world can a little guy from a slum have seen?

There are indeed things that I cannot build myself, such as airships, rail cars, and rotary balls, which are highly technical and have extremely complex structures.

However, I don’t believe that a kid who grew up in a slum can come up with the design drawings of an airship and a rotary ball.

Jiang Xilin didn't know about Laird's psychological activities, nor did he want to know. Anyway, his purpose of attracting the other party's interest had been achieved.

Jiangxi Lin immediately took out the design drawings of a charcoal stove and barbecue grill and handed them over.

"Mr. Laird, how do you think this will be charged?"

Laird shook off the linen cloth and frowned at it for a long time.

It’s not that I don’t understand or don’t know how to do it, but I’m just wondering why the skinny boy in front of me has so many weird ideas.

Forget about the flat-bottomed pot, like the soup pot with tenon buckles, he never understood the reason why it was made like this.

But since the customer is asking for it, there’s nothing to say. Even if it’s something weird, you just need to pay for it.

"Thirty copper buckles, please give me a deposit of fifteen."

Jiang Xilin directly took out a silver enamel and handed it over.

Laird took it, looked over it over and over, and then put it in his pocket after confirming that there was nothing wrong with it, and continued,

"There are still five copper buttons left."

Jiangxi Lin:……

Damn, this rough guy has a really dark heart. Although the Kingdom Financial Supervisory Committee clearly stipulates that 1 silver enamel and 10 copper buckles are equivalent, in actual transactions, they are all equivalent to 1:12 to 1:20.

of.

"Give me back the silver enamel, and I'll give you fifteen copper buckles."

Laird frowned slightly, was silent for a moment, and waved his hand with a pained face.

"Forget it, just one Yin Lang."

"Haha, there's no need to force it."

Jiangxi Lin was not used to him.
