From the first day, Sun Yi noticed that there were many hares active in the fields outside the camp in the woods. Pen "Fun" Pavilion www.biquge.info

Hares like to eat tender grass and to spoil crops. But the people in the camp could not do anything with the hares.

If hunted with a bow and arrow, the hare hides in the high crop fields and cannot be detected at all.

Digging traps, hares are too cautious. If a hare notices a change in the path it usually takes, it will avoid it.

There is also the lasso, but the hare often bites off the rope of the lasso.

The only thing that works is the sling, first bend a branch, make a mechanism to fix, connect the lasso to the mechanism, when the hare is struggling with the lasso, trigger the mechanism, bounce the branch and hang the hare high. But where are there so many suitable branches in the crops?

When people occasionally bump into hares, it is good to be able to catch them, but more often they can only stomp a few feet and scold a few words.

Sun Yi had been fighting the idea of these hares for a long time, and it was not until the copper wire was made that there was a feasible way - to lower the copper lasso.

The hare has a quirk, which is that he likes to go the old way. As long as you are not disturbed, you will walk the same path every day when you go back and forth to eat in the nest. The eyes of the hare protrude on the sides and there is a blind spot in front of it, so the hare does not like to walk in dense grass. They usually follow the ridges of the fields, stepping on a faintly recognizable rabbit path and leaving droppings.

As long as the rabbit diameter is confirmed, you can use copper wire to circle a looper slightly larger than the rabbit's head, tie it to the wooden peg, and nail it to the top of the rabbit diameter.

Since the hare's eyes are on both sides of the head, they do not notice the copper wire sleeve hanging directly in front of it, and the hare will put the head in it when passing through the copper wire. The lassoed hare will only push forward, and the more it struggles, the tighter it will become. In order to prevent the copper wire loop from directly strangling the hare, Sun Yi deliberately tied a knot two inches at the end of the copper wire snare.

Taking advantage of the dawn, Sun Yi took a group of robes and called the orphans to scout the traps under the rabbit path in the crop field.

Like any university dormitory in later generations, the children were only together for two days, and the eldest was discharged, the second, and the third until the end of the pomegranate. It's just that Sun heard that it was really awkward for these little hairy children to call themselves "master", so he asked them to call themselves "brother". So in addition to the "big brother" who is the boss of the platoon, these orphans also have a "first brother" like Sun Yi.

When the children heard that they were going to catch hares, they screamed excitedly, and ran around Sun Yi and a group of robe brothers, and after a while, dozens of sets were laid.

The next day, just after dawn, a child stumbled to Sun Yi's shack to report, "Brother Yi, it's terrible, I caught more than a dozen hares in one night!" ”

Sun Yi followed the children to the outside of the camp in one go, and found that not only the children, but also a dragon and a few robe brothers also got up early in the morning. Brother Pao smiled one by one, everyone carried two rabbits in their hands, and children kept shuttling in the crop fields, and from time to time there were excited shouts.

The fifth brother couldn't help but sigh while carrying the rabbit: "The copper lasso can not only be used for rabbits, but also for yellow wolves and foxes." When I go out in the future, I'm afraid I'll really eat this copper wire. ”

A child yelled at Sun,

"First brother, there are the most rabbits in the soybean field! I've caught six or seven! ”

Sun Yile took a hare, feeling that the hare's hind legs were particularly long, and it was very energetic, and he wanted to escape by kicking it, but if he didn't make any effort, he couldn't cage it.

Sun Yi turned the rabbit over, and found that the hare's ears were also relatively long, and just wanted to see if the hare's eyes were red, the hare took a bite and bit Sun Yi's hand.

"Hey, the rabbit is in a hurry and really bites!"

Sun Yi felt hot in his hands.

Sun Yi took out a roll of white nylon rope from his pocket and tied it to the rabbit's hind legs three times and two times.

The nylon rope is an essential tool for Sun Yi in the wild, and the rabbit is tied, and there is still a long one left.

Sun Yicai was reluctant to cut the rope short, so he coiled the extra rope in his hand and held it in his hand, just like walking a dog.

Sun Yigang put the hare in his hand on the ground. The hare jumped up as soon as it jumped, and its long legs were particularly obvious, and it was like a small deer.

The hare jumped more than a meter high, and turned around with a strange flick leg in the air, turning 180 degrees.

When it landed again, the hare jumped straight forward, and scurried out a few meters at a time.

Sun Yi hurriedly put down the rope.

The hare does not run away in a straight line, and after a few jumps it changes direction, and it seems that there is no idea of what to expect.

It wasn't until one time the hare jumped high and was struck back by the nylon rope that the hare had the right idea, and jumped up again and again, and was pulled back, and was pulled back again......

The rabbits that Sun Yi had seen before were all rabbits like "the little white rabbit is so cute and loves to eat radishes and vegetables".

When the rabbit squatted on the ground, Sun Yi couldn't see the rabbit's legs, it was a round hairball, which was simply two animals like the hare in front of him.

Catching the hare, Sun Yi's first thought was - raise!

Rabbit meat, rabbit skin, and rabbit fur are all needed for the ironwood camp.

However, the hare in front of him is too wild, can it be domesticated?

Sun Yi checked on his mobile phone, and the rabbit and the hare were actually two animals at all!

There are 22 pairs of chromosomes in rabbits and 24 pairs of chromosomes in hares, and the relationship between the two is farther than that of horses and donkeys, and it is impossible to cross and give birth.

Mobile phone information unfortunately shows that the hare cannot be domesticated until later generations!

Sun Yiyi gave up captivity. I wanted to find a place surrounded by water to try stocking, but Sun Yi did an experiment and threw the hare in the water, and the hare swam out of the way.

There is no way, for this all-powerful animal on land and water, you can only kill.

Sun Yi arranged a dragon to lead the robe brother to slaughter and peel the skin in a unified manner, although the rabbit skin is small, it can become a lot if it is small. By the way, take the hare to practice and kill the hare by cutting the carotid artery.

Brother Pao practiced stabbing the kidneys and cutting the neck yesterday, and the technique was skilled, but he had never fought in actual combat.

A dragon took the lead, pulled out the dagger with great interest, and fell with a dashing and accurate sword, and was immediately moistened by the blood of the hare gushing out.

The onlookers laughed heartily at the orphans, the robes, and the people.

The happiest were the two blacksmiths who came to see the excitement, and the copper wire they pulled out was a big deal, and Sun Yi couldn't stop praising their skill.

The people took out copper coins one after another, begging the blacksmith to turn them into copper wire.

There were fewer people, but Sun Yi pulled the two blacksmith masters aside, took out two broken copper wires, and looked serious.

"I found that the copper wire is thick and thin, like these two are uneven in thickness, and they were broken alive by the hare, what is going on?"

The blacksmith master who proposed to sing the iron was surnamed Xue, and Master Xue scratched his head, "In order to rush the work, the copper wires are all pulled out of the big stones, and the thickness is estimated." ”

Sun Yizhengse: "It can't be like this in the future." The demand for copper wire will be more and more in the future, not only for lasso, but also for other important purposes, the quality must be guaranteed, and there must be a standard. ”

It is a shame to say that China's wire rod industry in later generations did not have its own standards, resulting in three domestic wire rod specifications, namely British wire gauge, American wire gauge, and Birmingham wire gauge.

At that moment, Sun Yi casually picked a standard, converted the size, and specified the thickness of the copper wire from No. 1 to No. 40.

Sun Yi told the blacksmith to make the mold first, and then draw it step by step, and he will find that it is actually more time-saving and labor-saving to refer to this standard.

Master Xue listened carefully, while another slightly older master showed more or less disapproval.

Sure enough, the master said: "Master's method, the size of the copper wire is hard-specified, if the thickness that someone wants to make is not in the number, what should I do?" ”

Sun Yiyi: "That's non-standard parts, and the salary will be more." ”

The old master nodded with satisfaction.
