"Huh?" He Jun couldn't believe it, "You're not blinding me, are you?" ”

Liu Er immediately quit: "Xiao He, what are you talking about, how old is my dad?" Besides, what are you doing? ”

"That's it!" Uncle Liu said with a smile, "In the words of you young people, if you don't give me money, what am I doing with you?" ”

He Jun hurriedly said: "Uncle, I didn't mean that, I just thought it was too surprised, you go on!" ”

"Listen to me, and you won't be surprised." Uncle Liu said, "Give me your axe!" ”

He Jun immediately complied, and after Uncle Liu got the axe, he compared it and said, "What about the broken chair, bring me one of the legs." ”

Douzi jumped up all of a sudden: "I'll go right away!" With that, he ran out of the house.

Liu Er said worriedly: "Is this kid reliable?" ”

"We need people now." He Jun replied non-asked.

Liu Er was silent for a moment and nodded heavily.

He had knocked on all the doors of his unit in the morning, but in the end he only found He Jun, and after seeing the warmth of the human relationship and the cold and cold world, Liu Er would rather believe in ghosts than those indifferent neighbors in the same unit.

Uncle Liu also asked, "Xiao He, what is the idea of low?" Let's talk to my old man first. ”

"Uncle, I have some ideas, but I haven't thought about them all......"

"It doesn't matter, my old man has no other abilities, but he has lived a few years longer than you, maybe he can help you with his staff, don't think my old man is long-winded." The old man said.

"Look at what you said, it's a good thing I can't even ask for." He Jun hurriedly said, and just as he wanted to continue, Douzi had already run back with a chair leg and handed it to Old Man Liu with both hands.

The beans were brought from the wooden square that was located on the side of the back of the chair, half of the legs and half of the skeleton of the back of the chair, with a lot of broken stubble on it.

Thanks to a few of them, they were able to find this kind of wood

The three of them immediately stopped the conversation between them, and the old man took the chair legs, and nodded after comparing the length: "You see, this chair leg is about two and a half feet, and it is just used as a crossbow." ”

The three people, including Liu Er, were staring at each other, none of them could associate this piece of wood with a long-range weapon like a crossbow, just looking at the stubble on it, it was almost the same as a mace.

The old man picked up He Jun's axe and compared it on the leg of the chair.

He Jun hurriedly took out the dagger on his waist and handed it over: "Uncle, use this, the axe is too heavy and inconvenient." ”

The old man smiled, put down the axe, took the dagger, and said, "Now this wooden square is the crossbow body, with the head below and the tail above." As he spoke, he pointed to the side of the end of the wooden square, and used his knife to cut down diagonally, "Cut a gap here, cut the part by the tail diagonally, and sharpen the other end vertically." ”

As he spoke, he stood up the knife and made a vertical cut.

He Jun seemed to have an understanding: "You mean, use this place to hang strings?" ”

"Yes!" The old man smiled happily, "After digging, pick another groove on this small inclined plane, put a small piece of wood in it, leave the piece of wood a little longer, and press it on it after hanging the string, and the piece of wood can push the string out!" ”

The old man made a downward motion, and his eyebrows danced.

Speaking of which, He Jun didn't have to listen anymore, and he knew what to do later.

The crossbow is more advanced than the bow in that the crossbow can be charged, aimed and then fired, and this is done by the crossbow machine.

He Jun has seen some pictures of crossbows on the Internet, and the current crossbows, the shape of the crossbow machine is similar to the bolt, the more high-end the product, the more like a firearm.

And the simple crossbow machine that Mr. Liu said is absolutely so simple that it can't be simpler, to put it bluntly, it is a lever installed on a small slope, which looks a bit like a rocker, press one end, and the other end will lift the hanging crossbow string to achieve the effect of shooting.

The part that the old man didn't finish is also very simple, it is nothing more than to open a straight arrow path on the wooden square, and then fix the suitable crossbow strings and crossbow arrows, and finally make an aiming device to adjust the accuracy.

But when the question came, He Jun couldn't help but ask: "Uncle Liu, is such a simple guy powerful?" ”

"Absolutely!" The old man said with great certainty, "There is no problem at all in shooting people's bones, but the range is a little shorter, and with a crossbow arm with better elasticity, the power and range should be fine." ”

"Dad!" Liu Er was very surprised, "Did you use this thing when you were fighting?" ”

"Alas, when I joined the army, I used a big sword and a spear, and if I knew how to make this thing, I wouldn't have to die so many people." The old man's face was full of unwillingness and remorse.

"And where did you know about it?" Liu Er asked curiously.

"Where else can it be, on TV, of course!" Uncle Liu glared at Liu Er, "I just played it a few days ago, and the archaeology dug up a few human bones, saying that it was a woman's ribs, and there was a stone arrow on a broken bone, and the research said that it was killed by a crossbow." In the end, he made such a simple crossbow, and pierced the wooden board with an arrow, saying that if he shot a person, he would definitely break his ribs. ”

He Jun almost stopped laughing, he didn't expect that the answer would be like this! Douzi simply couldn't hold back and burst out laughing.

The expression on Liu Er's face was almost the same as being constipated for two months: "Dad, there is really yours, can this work?" ”

"Why not?" The old man said, "If you don't try, how do you know if it works?" Besides, do you have a better way? ”

In a word, the three of them ran out of electricity together.

He Jun was the first to say: "You're right, you have to try it to know if it works...... But what should a crossbow arm be made of? In this era, bamboo or something shouldn't have appeared yet, right? ”

Not only bamboo, this place is full of ferns, although there are many tall plants, but in He Jun's memory, ferns have no woody, and it is easy to find a material suitable for crossbow arms from so many unknown plants?

"I can't help it." The old man said simply, "The community is big or small, and there is always something to find alternatives, right?" ”

What is resilient?

Several people's brains kicked in unison.

Before He Jun could come up with a clue, Douzi suddenly snapped his fingers with a smile: "I thought about it, I have a tensioner, can the spring on it be used?" ”

"Puller?" He Jun thought for a while, his eyes lit up, "I should be able to try, but the spring can't be used as a crossbow arm, so I can only put the spring on both sides of the crossbow like a diver's speargun, maybe it will work!" ”
