Jin Zhenren was dismantling a camera, and when he saw Yin Jian coming in, he wiped his hands and asked, "How did you finish the homework assigned to you last time?" ”

Yin Jian knew Jin Zhenren's temper, so he didn't mention the matter of forging the sword for the time being, and said according to his meaning: "I have thought of a plan, teacher, you see if it will work." ”

Not long ago, he complained to Jin Zhenren that every time he used the magic circle, he had to spend time drawing it, and after drawing it, the magic circle could not be used immediately, so he had to let it run for a period of time in order to be full of spiritual energy, if he really couldn't wait, he had to use his own spiritual power to help charge the magic circle, in short, it was very troublesome.

Therefore, he suddenly thought that it would be much more convenient if he could draw a batch of magic circles in advance and make them into a book, and put them there for the time being, so that the magic circles could be slowly charged, and when needed, they could be used directly.

At that time, Jin Zhenren didn't laugh at his whimsy, and said lightly: "What's so difficult about this." ”

Yin Jian smiled bitterly: "Of course, the teacher is not difficult, but the apprentice thinks that it is not simple, the magic circle is not a plan, how can it be drawn on paper." ”

Jin Zhenren said expressionlessly: "Paper naturally can't be ordinary paper, and painting can't be ordinary painting, just prompt so much, you think about it yourself, and tell me the answer next time you come to class." ”

After Yin Jian went back, he thought about it for a long time, and gradually sorted out a line of thought. Coincidentally, Xiaoqing came over to chat after finishing housework, and Yin Jian discussed this topic with her.

Xiaoqing has not cultivated for thousands of years in vain, and he also has a deep attainment in refining weapons, and put forward some very valuable ideas according to Yin Jian's creativity, and finally the two discussed and came up with a set of design plans.

As Jin Zhenren suggested, Yin Jian's zuò magic circle atlas does not use ordinary paper, but "fish and goose notes", a three-grade material that looks similar to ordinary rice paper.

The fish and goose note is also called "ruler", which can hold and preserve thoughts for a long time.

For example, if you visualize an apple and put it in a fish and goose note, and then cut off the thoughts, the residual thoughts will not dissipate as soon as they are in the air, and they will remain in the shape of an apple in the fish and goose notes, and they will not expire for decades.

Yin Jian can use his thoughts to visualize the array out of thin air, and then save it into the fish and goose note to turn it into a physical array, and when he wants to use it, just pull one down.

Xiaoqing's Xiaoyao Cave happened to have a roll of fish and goose notes, and now there is only one machine spirit missing. Xiaoqing rummaged in the warehouse again, and finally found an ancient painting, in which the parasitic demon spirit attributes were consistent with the fish and goose notes, which could be used as a machine spirit.

Next, Yin Jian and Xiaoqing went into battle together, trying to persuade the painting demon cutie to move. Don't look at the painting demon beauty for hundreds of years without leaving the house, I know in my heart, this is called the first salute and then the soldier, if you don't know the current affairs, the result is still the same, it's better to agree quickly.

The instrument tire and the instrument spirit are all prepared, plus a few auxiliary materials, a three-grade Zhuji Dan and a three-grade condensing pill to nourish the spiritual power of the demon eyebrows, Yin Jian began to practice under the guidance of Jin Zhenren, the fish and goose notes are flammable and cannot be smelted with ordinary flames, this time the bagua furnace set up a Xuanwu array, and the fish and goose notes were refined with the cold flame of the northern nong.

The furnace was also very powerful, and it took a short time to refine this three-grade magic weapon "Circle Catalogue". However, the gossip furnace was too big and troublesome, so Yin Jian had to climb the ladder to get in and take out the refining magic weapon.

After searching for a long time, he finally found a thick book in the south, which was the refined "Atlas of the Law Circle".

Yin Jian picked up the "Atlas of the Law Circle" and asked the machine spirit: "Why did you hide here?" ”

The painting demon Meimei replied: "The Xuanwu cold flame is so cold, people hide in the Vermilion Bird position to keep warm......

"You're a stupid goblin, and you're not afraid of being burned!"

After coming out, Yin Jian Xingchong used his thoughts to draw a magic circle and included it in the atlas, and now he can be regarded as practice makes perfect, and a few minutes of meditation can complete a magic circle.

Qinglong White Tiger Vermilion Bird Xuanwu Gou Chen Five Gate One Yuan Array, plus the two-element Wind and Fire Array and Earth Demon Array, as well as the Four Elephants Shading Array that he had learned before, Yin Jian finished painting in one go, and now he was embarrassed that he would only have these few magic circles, and it was really suspected of pretending to be forced to make a picture album solemnly, and it seemed that he had to learn a few more magic circles to fill the façade.

He doesn't care about the face project here, and the poor little white sister doesn't know how many brain cells he has to exhaust to death.

The "Atlas of the Law Circle" was recognized by Jin Zhenren, and Yin Jian dared to propose the idea of forging a sword to him.

Jin Zhenren took out a sword-casting notebook and showed it to him, which listed hundreds of various types of flying swords, grades, materials, and characteristics were clearly written.

"You choose a favorite flying sword from here, preferably about three grades, too low-level power is limited and will be eliminated soon, too high-level you can't control it now, and it's useless if you can't wield the power."

"Okay." Yin Jian agreed to open the notes, found the second-grade and third-grade flying swords according to the table of contents and read them carefully, and the rest of the chapters did not move at all.

Jin Zhenren nodded secretly, the apprentice is good, after this period of cultivation and polishing, his concentration is far better than before.

Yin Jian read through these two chapters and determined that "Shadowless Flying Sword" was the most interesting.

First of all, this flying sword is generally a second-grade, and the highest will not exceed a third-grade, his current spiritual power is a one-star, and it is suitable to use a second-grade flying sword after breaking through to a two-star in a few days.

Secondly, the shadowless flying sword is just as its name suggests, it is a stealth flying sword that flies up without a shadow, the sword tire of the wind attribute is light and sharp, and it is best to match it with the sword spirit of the wind attribute, which can swing the degree advantage to the extreme. Such a flying sword, a hard encounter may not be satisfactory, and it is the most suitable for sneak attack and assassination!

In Yin Jian's view, the flying sword is not so much a cold weapon as a miniature guided weapon, and the biggest advantage is long-range strikes and sneak attacks.

Finally, there was another reason for choosing the Shadowless Flying Sword, the main materials needed to forge this sword included pure gold, five-colored spirit stones, and "thousand-year-old snake blood", which happened to be in stock in his hand.

As the saying goes, "ten birds in the forest is better than one bird in hand", instead of looking for those strange materials that have not even heard of the name, I don't know what year and month can be cast into a flying sword, he would rather look at the existing materials and place an order, try his best to refine the flying sword, and then take the flying sword to fight monsters and clean up resources, the efficiency will be relatively high.

In addition to efficiency, he also considered technical factors.

The sword tire of the shadowless flying sword needs to be engraved with various magic circles, which play the functions of rust prevention, reinforcement, addition, and sharpness, etc., most of which are one-yuan or two-dimensional magic circles, which are relatively easy to deduce, but the most core of the "invisible" magic circle is four-elemental, usually quite complicated, and it is very difficult to deduce. With this alone, casting the Shadowless Flying Sword will save a lot of time and effort.

Of course, luck is not always on his side, and the casting of the Shadowless Flying Sword still lacks a major material - more than 500 years of psychic ivory.

It does not mean that the tusks can be channeled after being pulled out and placed for 500 years, but it must be an elephant that has lived for 500 years, and the extracted teeth can be used to forge swords.

Elephants that have lived for so long are sure to become sperm without asking.

"Huh? Elephant! ”

Yin Jian suddenly remembered someone.
