Jiayi led the two cows he brought back to the hillside to graze, and Daqing and his main palace Niangniang were grazing leisurely on the hillside.

I don't know if it's his own delusion, he always feels that the original cow is a little sluggish, and even his body seems to be a little thinner. He hurriedly led the newly brought back cow to Daqing, and touched Daqing's head: "These are the two concubines I found for your harem, see if you like it or not, this is my careful selection!"

These two cows were bought by Jia Yi from farmers at a high price, but fortunately, the weather has entered summer, and there is no need for cattle to plough the land for the time being, so it is relatively easy to buy cows.

These two cows are sturdy, their coats are shiny, and their owners take care of them very carefully, and they were not ready to sell them, but Jia Yi took advantage of the lord's authority to "take them by skill" and doubled the price. Originally, I wanted to buy a speckled cow or a white cow, and cross it with Daqing to give birth to a spotted cow, so that it looks like a cow, but unfortunately none of these are available.

After setting up the cow he had brought back, Kaichi returned to his room, took out a drawing board and sat in the sun and began to practice sketching.

He said he was sketching, but he was actually drawing lines all the time.

When learning the rune circle, Imu said that it was not enough for the optics to understand the runes, and that it was necessary to practice more to improve the stability of the hand. Make sure that you don't shake your fingers when drawing runes, resulting in uneven line thickness, and the magic will have a problem.

Therefore, Jiayi began to practice sketching to exercise his pen holding stability.

He had never studied sketching in his previous life, and he didn't know anything about light and shadow or composition, but he didn't care if he thought that he wasn't learning to paint himself.

He first asked his partner to bring graphite and clay and mix it to make a pencil lead. Then the wooden rod was cut out of a wooden stick and the pen barrel was made, so that the pencil was born.

This also adds a new item to the chamber of commerce in which Jiayi participates, the pencil is cheaper, and the money earned is far worse than the fountain pen, so Eunice is not very interested in this, but the category of the pen is enriched.

When Jia first started to practice sketching, he didn't practice anything, he drew lines, starting from the left side of the paper, from the top to the bottom of the paper, one line to the end, then a few millimeters away, and then drawing a startling line, until the whole sheet was full, and then he came sideways and continued to draw. Draw until the whole sheet is black, then turn it over and continue drawing.

Until the end, the paper used by Jiayi was black and black, and it became a piece of graphite paper. He kept drawing like this, and his hand was now very steady, and the lines he drew were straight and even, and the two lines were a third of a millimeter apart and would not intersect at any point.

Not only that, but he can also control the tip of the pen to draw lines that vary evenly from thick to thin, or draw mosquito coil-like spiral circles that fill the entire sheet without intersecting.

Over the past few years, Jia has used up hundreds of pencils, and it can be said that his line ability has become a bit superb, and even Yimu has to admire.

But the sketches he drew were not very good, at most they were somewhat similar, but they were far from excellent. He originally looked at the big touch on Weibo, and he was able to draw black and white photos, and he was at most an apprentice - except for drawing geometric figures.

He drew a line for a while, came to the hillside where the cows were grazing, and began to draw the cows.

As Daqing's injuries got better in the past two days, he felt more and more domineering, and even the calves born by cows were driven aside. Kaichi is ready to sell the calf because it is a bull.

Looking at Daqing, who was surrounded by three cows, Jia Yi couldn't help but feel a little envious. 14 years old, it should be almost developed, he looked at the little brother and thought.

The two newly bought cows are still a little afraid of Daqing, a little far away, only the first cow has been by Daqing's side, and occasionally Daqing.

Depend on!

Jia was a little stimulated when he saw it, and he was sprinkled with "dog food" by the cow. The cow didn't do this before, could it be that being bred by Daqing would also add emotional intelligence? And is it the season of estrus?

He also doesn't remember when his cows usually go into heat, but there was no sign of this before leaving.

Daqing, you can't still have your own hair and love aura, a proper protagonist template, or the protagonist of Xiao Huangwen.

Maybe Daqing has been lonely for too long, in that area, not to mention the same kind of green cattle as Daqing, there are not even ordinary bison. Daqing has lived for so long, probably the first time he has a girlfriend. I don't know who Daqing's parents are, whether they were born to Niu and Niu.

If it hadn't been accepted by Imu, I don't know if it would have become extinct, but now it is crossbred with ordinary cattle, and if a calf is born, it is not considered a pure breed, right?

However, if you count only by the Y chromosome, if Daqing gives birth to a bull in his offspring, then he must have inherited the Y chromosome, and if he has always guaranteed that the offspring have a bull, at least the Y chromosome will be guaranteed to be inherited.

Then, in the future, you can say to the girl, I have an ancestral thing for you, an ancestral chromosome...

In this case, if some excellent genes and genes that determine talent can be engraved on the Y chromosome, then it can be guaranteed that the males of the offspring will be able to have extraordinary talents.

Now, the only question remains, is it genetically inherited from the otherworld, or is it determined by the XY chromosome? What if XY is female, YY is male? Then the female can always inherit the X chromosome. It's really nothing, at least one chromosome can be inherited forever.

Thinking like this, the sun made Jiayi a little drowsy, and he didn't even care about what he painted.

Then, he looked down at the cow he had drawn, and found that it was all out of order, its head stretched too far, and its body too thin to be shaped.

"Kaichi, what are you drawing? You're not going to tell me it's a cow, are you?"

Dai'er didn't know when she came behind Jiayi, looked at the manuscript paper in his hand, and asked with a smile.

Jia Yi turned around and looked at Dai Er, who was smiling and smiling, and her face was faintly red. I was just thinking about something big about heredity, and I was a little embarrassed to suddenly see a girl.

However, he didn't have any thoughts about Dai'er, although Dai'er has become more and more delicate in the past two years, especially with the study of magic, there is more of an intellectual aura on his body. But she's still cute overall, it's okay to be a sister, but to do anything else, her figure is still too shriveled.

"How is that possible!" Jia Yi shook his head and quickly retorted, "This is the design I drew, yes, the design drawing!" Although Jia Yi himself knows that what he draws is very ordinary, he will never admit it himself.

Moreover, in the Lime Pine Valley, his level of painting is the highest, and even within the entire territory, his paintings are the most similar.

Dale looked at him with a stiff mouth: "Then what did you design?

"What horn stool, where is the cow? Where are the horns?" said Kaichi, still stiff-mouthed, thinking about how to get around.

Suddenly, he had an idea, and drew a few straight lines on the corbel, straightened the leg, and then drew a circle on the corbel, and several more spokes on it, forming a wheel, and the hind leg was treated in the same way. Then there is the head of the cow, the horns extend directly upwards and then flattened out, becoming a handle, and a stool is directly outlined on the back of the cow, so that a two-wheeled manpower self-driving car appears.

Next, he used his fingers to blur away the parts he didn't need, and then used a pencil to blacken the parts he needed to thicken the lines. Probably because of the potential stimulation, Kaichi suddenly felt like a god, not only drawing the outline of the car, but also deepening the background shadow in the process of painting the unwanted parts, making the car appear more three-dimensional.

In this way, the world's first two-wheeled human-powered self-driving vehicle appeared in the manuscript paper on Jia's hand.
