When Ye Maoyan went to discuss with Kang Di about tinkering with the sail sled, Shang Tao also went back to draw drawings.

Because he couldn't expose the black technology of mobile phones, he had to draw some drawings of the parts that needed to be custom-made by the blacksmith for the crusher and blender used to make chili sauce.

After Shang Tao drew the drawings of those parts, he drew a three-dimensional glass storage jar with a wooden lid by referring to the shapes of those borosilicate glass storage jars in the later generations of the earth.

After the wooden lid was drawn, Shang Tao took out another piece of paper, and then drew a top-down plan of the wooden lid on it, which was actually a circle. Then, Shang Tao drew a LOGO in the center of this lid, the left side of the LOGO is a girl's side face, and the right side is written with the words "Jia Yinger" from top to bottom.

However, Shang Tao has never learned to draw, and it is okay to draw simple drawings according to the design drawings, let him talk about portraits, he really has no talent in this area, and he is not satisfied with the painting several times.

So, Shang Tao thought that it would be easier to find a model, so he shouted out the door: "Jiajia, come back." ”

Soon Konka came back in a hurry, and asked, "Why is Brother Shang Gongzi calling people?" ”

"Come here, stand in front of me, go a little further, turn around, face the door, yes, yes, keep smiling, well, that's it."

"Brother Shang Gongzi, what are you doing? Is it for me to paint? Konka asked puzzled.

At this time, Li Ling'er, Wang Yingying, and Duo'er also walked into the house.

"Brother Shang Gongzi, are you painting Jiajia?" Li Ling'er looked at Shang Tao holding a pen in his hand and drawing something on the paper, so he took two quick steps and stood behind Shang Tao curiously.

Then, Li Ling'er said disgustedly: "Brother Shang Gongzi, you painted Jiajia so ugly." ”

"Oh, no, no, no." Konka heard that he was being painted ugly, and immediately quit.

Shang Tao thought that Li Ling'er was a former Oiran, so he stood up directly, and then pressed Li Ling'er to sit on the stool, then stuffed the pen into Li Ling'er's hand, and said: "Ling'er, come on, come on, you come to paint, you are a talented and beautiful Oiran in the Celebrity Pavilion, and the painter must be not far behind." ”

"Brother Shang Gongzi, she is your woman now, not an oiran." Li Ling'er pouted and protested dissatisfiedly.

"Okay, Ling'er is my woman, as long as you draw well, the master will serve you well tonight."

"Hmph, I'm not rare." Li Ling'er took a piece of paper and spread it on the table, and asked, "How can I draw it?" Do you have any requirements? ”

"You just use a stroke to outline Jiajia's side face, which should be smooth, vivid, concise and clear." Shang Tao gushed out his request.

"In this case, you can't draw that effect with your pen, so you have to change the brush." Li Linger said.

"I'll pick it up, I'll pick it up." Wang Xiaoying excitedly turned around and ran into the west wing, quickly took out the brush and inkstone, and then poured some water into the inkstone, and began to help Li Ling'er study ink.

After everything was ready, Konka stood with his face sideways again, Li Linger glanced at Konka, and smoothly outlined a vivid line on the paper with the tip of the brush nose, although it was only a simple stroke, but it was similar to Konka, and it was indescribably delicate and moving.

Li Ling'er turned her head and saw Shang Tao staring at the lines of Konka's side face on the paper, so she asked with a little smugness: "Brother Shang Gongzi, do you think it's okay?" ”

"Okay, that's great, you'll be my royal cartographer from now on." Shang Tao said, then picked up Li Ling'er's little face, and kissed her on the small mouth, only to look at Duo'er standing behind him with hot eyes.

After Shang Tao let go of Li Ling'er's small mouth, he continued: "You write the words 'Jia Ying'er' vertically on the right side. ”

"Brother Shang Gongzi, is this the brand you got for the chili sauce?" When Wang Xiaoying heard Shang Tao say the words "Jia Ying'er", she immediately understood Shang Tao's intentions.

"Hmm."

Shang Tao thought about taking some brands such as "Lao Gan Ma", "Lao Gan Dad", "Hot Girl", "Shang Haojia" and so on, but in this way, he was worried that the Tang Emperor would be worried about it, so he simply took a brand like "Jia Yinger", which happened to take the last word of his three women's names, and then "Jia Yinger" happened to be a homonym for "Jia Yinger".

The kiss just now made Li Ling'er's heart sweet, she gently dipped the brush in the inkstone, and then raised her head again and asked, "Brother Shang Gongzi, what font do you want?" ”

"Well, I want to think about it, to be beautiful, beautiful, not cursive, to be recognizable at a glance, and not too complicated, easy to carve by woodcarvers." Shang Tao thought for a while and said.

Li Ling'er picked up the pen and wrote, and soon the three juanxiu lines jumped on the paper, complementing the side face lines on the left, and it looked really atmospheric.

Shang Tao couldn't help nodding his head, and said with satisfaction: "Well, it's very good!" Ling'er, you can redraw these pictures later. As he spoke, Shang Tao moved the mouse, found the drawings of the parts that needed to be customized, and pointed them out to Li Ling'er.

At this time, even Konka gathered around Li Ling'er and watched.

"Sister Ling'er, your painting is amazing, why don't you go back and help me paint a portrait." Kang Jia hugged Li Ling'er's neck and said coquettishly.

"You took it with the mobile phone that Brother Shang Gongzi gave you, it's not a hundred times better than my drawing, why do you want me to draw it." Li Ling'er said sourly.

"That's different, besides, I can't take out the phone anymore, I want you to paint me a portrait and hang it in my room."

"Sister Ling'er, can you draw one for me too?" Wang Xiaoying also said weakly.

"Do you really want to paint?" Li Ling'er said with bad intentions, but what she thought was to draw all the clothes on their bodies later, anyway, she had seen the bodies of the two girls many times, and she had already memorized them in her mind.

"Hmm." The two women nodded in agreement.

"After the painting, you are really all hanging in the room?" Li Ling'er confirmed again.

"Hmm."

"Hmm. Since Sister Jiajia is going to hang it in the west wing, then I'll hang it in the east wing. Wang Xiaoying said timidly.

"Okay, then I'll draw the drawings for Brother Shang Gongzi, and I'll draw them for the two of you."

"Okay, then you can paint here, I still have some business, so I won't accompany you." Shang Tao left the room after speaking.

Shang Tao has just seen the detailed ratio and production process of the liquid rubber used in condoms, and he is now going to make a few condom molds.

The investigation team was very careful, because they were worried that the condom that Shang Tao made was too similar to a modern condom and there was a risk of exposing the identity of the traverser, so the condom mold drawings drawn simply removed the small head that protruded at the front end of the condom - that is, the seminal vesicle.

In fact, that raised little head is not just as simple as a seminal vesicle.

If the condom does not have the seminal vesicle, it is likely to puncture the condom when it hits at high speed, so from the perspective of cost, modern condoms use such a seminal vesicle design, so that the force of the impact will not be directly absorbed by the front end of the condom, so there is no need to worry about the condom being damaged and causing contraception failure.

Unable to design seminal vesicles, and to avoid strong impact to puncture the condom, the investigation team had to make a fuss about the materials.

As a result, the cost of one condom they made was higher than the cost of a box of condoms in the next generation on earth.

However, considering that Shang Tao will not have competitors in Shanzhai Datang, it doesn't matter if the cost is higher, as long as he sets the price higher.

Even this kind of condom without seminal vesicles should be better in terms of use experience, you must know that the greater the pressure, the greater the motivation, and the huge resistance when ejaculating will only make the man's pleasure stronger.

The investigation team gave a total of two kinds of molds, one is a condom mold without bumps made of glass, and the other is a condom mold with bumps made of metal.

Correspondingly, glass can also be traced back to the detection and mining of quartz sand.

Shang Tao doesn't care much about the kind of non-bumpy condom molds made of glass now.

He came to the location of the big yurt that was originally used as a large living room, in order to prevent Kang Di and Ye Maoyan, this big living room has been changed by him into his own workshop, so that Kang Di and Ye Maoyan have no excuse to always run into their yurt.

At this moment, it was already full of his various tools and materials, Shang Tao found a steel pipe with a diameter of about four centimeters, and then welded a three-centimeter-thick discus to the whole section, and then used an angle grinder to polish the discus into a sphere.

Then, Shang Tao used a pistol to drill a dense circle of dimples on this simple condom mold, because there is no finer drill bit, so the diameter of these dimples is three millimeters thick, which is much larger than the bumps on the bump condoms in the future generations of the earth, which will undoubtedly cause a waste of cost, but if from the perspective of use experience, this kind of condom with large bumps, women will definitely prefer it.

It took Shang Tao a long time to drill a dimple on the three condom molds, and then used a cutter to cut out a ring-shaped groove about one millimeter deep at about 10 centimeters, which is the closing of the condom and the function is to prevent the condom from being accidentally torn.

Now everything is ready, only the rubber liquid used in the condom is needed, and when the time comes, as long as the mold is immersed in the prepared rubber liquid, and then take it out to dry, and then take the dried condom off, turn it over so that the bump is facing outward, and you can use it happily.

Looking at these three condom molds, Shang Tao suddenly had an urge to try.

Walking outside the door of the living room with three molds, Shang Tao faintly heard the sound of a woman calling for bed in the living room.

Shang Tao suddenly came to his senses, and quietly opened the security door, and saw four women sitting in front of their laptops, watching intently a small movie that I don't know which AV actress.

Shang Tao entered the room without making a sound, then gently closed the security door, and then tiptoed towards the women......
