The muzzle of the gun is towards the door, like a god glaring angrily, and the black muzzle of the gun is ready to erupt at any time, which makes people shudder.

Such a powerful gun-shaped wind chime turned a blind eye, but pulled the original table against the wall out, and then she walked around to observe carefully, and did not take a second look at Lao Jing, who was ready to accept the adoring gaze of the woman he cared about the most because of his quick assembly of guns, and he was really embarrassed to remind the woman not to say a word of praise before starting his work, and finally had to sit quietly and watch the wind chimes before and after.

Ten minutes later, the wind chime suddenly ran out of the room, and within a minute, he ran in again, with a small bag that girls like to carry on their shoulders every day.

However, she still ignored Lao Jing's puzzled eyes, sat down on a stool next to the table, opened her bag and rummaged for a long time, and actually took out a few pencils from it that could only be seen on earth, and a small notebook of sixty-four open.

Jing Jun somewhat understood what the wind chime was for, and sure enough, the wind chime picked up a pencil, opened the small book, stared at the barrel of the gun for a long time, lowered his head and made a few strokes on the notebook, and then raised his head and began to observe.

In this way, after more than half an hour, the sound of writing and painting from time to time when the pencil fell on the room stopped, and the wind chime raised his little head, glanced at Lao Jing, who was waiting quietly on the side, smiled slightly, revealing a mouth full of white teeth, and said, "Big brother, look!"

As he spoke, he handed over the small book in his hand, and when Jing Jun reached out to take it, he saw that her green and white jade fingers were stained with a little pencil powder, and naturally wiped off the blue and black powder.

The wind chime tasted the feeling of Lao Jing's dry and warm fingers rubbing by, and his little face was slightly red, but he didn't say anything.

Jing Jun's eyes turned to the small book, and his eyes lit up immediately.

The small book is completely a side sketch of a Barrett heavy sniper, although the drawing is a little smaller, but every external part of the gun is clearly visible, and the size ratio of each part basically fits the size of the original gun standing on the table, this drawing is perfect.

"Is this really what you drew Lingling?"

Lao Jing glared and asked a sentence that was not level.

Sure enough, Feng Chime's careful care for Brother Jing just now was still sweet in his heart, but within two minutes, a nonsense suddenly came, and he said coquettishly: "Nonsense, wasn't I busy just now?"

Jing Jun also realized his aphasia, and hurriedly laughed: "Uh, it's the eldest brother's fault, in fact, I want to ask how you did it?"

"Humph!"

Feng Chime rolled his eyes, but with endless style, "What's so difficult about that, my dad is a mathematician, and he has a good reputation in applied mathematics, drawing drawings is like eating and sleeping, I have been drawing and playing with him since I was a child!"

"Oh, but drawing isn't a design major, my major in college was engineering design......"

Lao Jing was puzzled at this time and had a disagreement with the wind chime in terms of professional ownership, and sure enough, the latter raised his eyebrows when he heard this, and said sharply: "As far as what you can learn, mathematics is the theoretical originator of all science and engineering disciplines, and the corresponding mathematical model can be found for any achievement!"

Jing Jun said in his heart: "My grades were not bad when I was in school, why did I look like an illiterate person who didn't understand anything in front of this little girl...... Alas...... This family is simply a concentration camp for geniuses......"

After this, he also realized how unwise it was to argue with the wind chime about academic issues, scratched the back of his head, with a sudden expression, and admitted his mistake with a positive and sincere attitude: "Oh, I understand......", in fact, he was still confused about what the wind chime said.

The wind chime gave him another roll of the eyes, but instead of taking the opportunity to ridicule again, he took the small notebook, pointed to the picture and asked, "I just want you to see what is not suitable, such as where the proportions are wrong." ”

"No, at least now I can't see it, you're so good at drawing, but it's a little ......"

Jing Jun nodded and praised vigorously, and finally picked up the small book and turned two pages with a frown.

"Well, that's no way, I usually keep this little book in my bag, so I can record some questions that suddenly come to mind, oh yes, there are only five pencils left......"

The wind chime pouted and looked through the packet again, of course, there was nothing extra out of thin air.

Jing Jun sighed for a moment and said, "That's it, maybe Brother Niu and they have similar tools that can be used to draw pictures, and Mr. Xu makes paper in this world." ”

"Is it? Could it be that Mr. Xu also understands invention and creation?"

Wind Chime's eyes widened in suspicion.

"Well, I don't understand, I heard him say that he tried boiling a bunch of broken things according to the ancient papermaking technique mentioned in the history books, but I didn't expect to actually get paper that can be written, and that's probably it. ”

"Oh, okay, I'm going to eat first, I'm so hungry now, I'm done preparing things for them, and then I'm going to get the drawings for each part!"

Wind chimes patted their stomachs and said.

After lunch, the two of them got a pen and paper from Niu Ben, and went into the house to scratch the parts on the table, according to Niu Ben's meaning, he also came over to see if there was anything he could help, after all, he was also a very good foundry.

But Feng Chime thought that he was upset when he was concentrating on painting in proportion, and politely declined, saying that he was going to get it out first, and then explain to him how to build each part.

In fact, Niu Ben is indeed as Feng Chime thought, he is very interested in powerful guns, and he wishes he knew all about guns in an instant.

In the end, he also saw that the two of them seemed to really not want to see him at this time, so he also arranged other things for him.

In fact, there are a lot of things that he needs to deal with, such as the iron ore problem, which is easy to solve, the third battalion under the jurisdiction of Donghai Town is actually guarding a refined iron mine, which is one of the four major iron mines in the Eastern Continent, and the other three are the black iron ore in Southern Xinjiang, where the maces used by the crocodile warriors are basically produced.

In addition, the weapons made from the cold iron ore of the northern plains are extremely sharp, but the toughness is insufficient.

Then there is the hematite of the Tiger tribe in the northwest, the color of the ore is dark red, and it looks like the iron has been placed in a humid environment for too long and rusted from a distance.

The color of the refined iron ore in Donghai Town is gray and white, and the hardness of the iron made by simple exercise is not as good as the cold iron of the North Plains, but the toughness is more than that, and the weight is not as good as the black iron of southern Xinjiang, but it is enough for the Minotaur people, and the red iron in the northwest is comparable to each other, but the appearance color is different.

And this refined iron ore mining time is not long, according to the age of the continent is not more than 50 years, how many reserves no one has measured, and then the sea tribe invaded, one of the purposes is to plunder and occupy the mineral deposits here.

After the establishment of Donghai Town, the Ape Emperor mobilized 100,000 Minotaurs to garrison here, one is to prevent the Sea Clan, and the other is to use the excellent casting genes of the Minotaurs to mine iron ore on a large scale to supply the weapons of the Ape Clan.

And the Minotaur did live up to the trust of the Ape Emperor, giving full play to their casting talents, adding other materials in the process of quenching and extraction, and the strength and toughness of the iron tools smelted coexisted, so they gradually overshadowed the fame of the other three mines, and gradually became the first iron mine in the Eastern Continent in a short period of time.

Later, after looking at the raw materials added by the minotaur, the wind chimes were pleasantly surprised to find that they were similar to carbon, but slightly different, but they were more than enough to cast gun parts.

The third battalion is 800 miles away from Donghai Town, and a batch of ore and iron tools will come and go every few days, and Niu Ben ordered the general of the third battalion to tighten the guard of the mine on the one hand, just in case of an incident, and on the other hand, to transport a batch of ore as soon as possible, which is urgently needed recently.

But they had a hard time with another problem, which was where to find a high-level fire mage to come and help.

Babel City will definitely be able to find the characters of their camp, but there is no news for so long, then something must have happened, and now send someone to Babel City for help, whether it is a cow or a dog, they are not at ease, but if this problem is not solved, it will only be a pile of useless scrap iron.

Three days later, they still haven't reached a consensus on the issue.

Jing Feng and the two of them in the past three days are dedicated to developing a drawing model of gun parts suitable for the operation of the big guys, more than 200 parts and pieces, after careful consideration by Jing Jun, remove the most modern design is also more than 100 parts, and the wind chimes are drawn on the straw paper one by one to match the size ratio after the combination in the future.

In the process of careful calculation, analysis and drawing of the wind chime, Jing Jun sighed a lot, he was inadvertently struck by lightning into this world, thanks to the genius girl who met the wind chime, otherwise in the future, even if he has the conditions to make a gun, he will not be able to make a gun suitable for the use of the mainland orcs, and now he can't do the work that the wind chime does at all.

Don't look at the many guns that have been made on the factory floor with personal hobbies in the past, but those are all completed with the assistance of existing modern production and assembly equipment.

Now the wind chimes rely entirely on her meticulous scientific brain to complete the three-dimensional combination and splitting, and finally record the data accurate to the millimeter on paper, and then have to draw the outline, the hard work can be imagined.

After three days, although she liked this kind of work in her heart, she could see more or less haggard traces on her appearance, Lao Jing was distressed, but he couldn't help at all at this time, just softly persuaded her to rest early, drink more water and eat and so on.

As the saying goes, interest is the best teacher. It couldn't be more appropriate for the wind chime at this time, although her previous research direction was not in mechanical manufacturing, but there must have been a lot of violence in her genes, and she completed the drawing work after three days with such a large amount of work.

After lying on the table for three days, his body straightened up, stretched his waist with difficulty, and the blue and black circles of his eyes could not hide the excitement after the success, and pushed the thick stack of papyrus paper in front of Jing Jun, and said in a hoarse voice: "I'm done!

Lao Jing looked at a silly wind chime, especially her eyeballs that were bloodshot on weekdays, and her heart ached, so she hugged her tightly in her arms.
