It didn't take long for Douzi to take the heavy steel gall, although the round throat was not easy to hold, but it was very easy to smash the bones, and after a while, all the fangs on the jaw were successfully removed.

Because the jawbone and skull are connected together, it is difficult for the steel gall to smash the gums, whether it is to erect or put down the skull of the giant beast, the steel gall cannot exert the strength, and in desperation, He Jun had to give up the plan to remove the teeth, and directly knocked out all the upper teeth of the giant beast one by one.

The root of the fangs of the giant beast is thick and thin, and when it is smashed, it must be smashed at the root in order to harvest a relatively complete tooth, and if you are not careful, it will break from the middle of the fangs or even the tip, and as a result, after smashing all the fangs on the jawbone, only two-thirds of them will be harvested.

The remaining one-third was completely useless, hanging from the jawbone, looking like it had just been broken by an old punch and full of teeth, which was ridiculous.

However, several people were very tired, and no one had that extra mood, so the three of them returned to the building with the fangs that they had managed to get, and dragged their tired bodies to the three-unit 901, which was used as a studio by a few of them.

The group cleaned all the fangs in 901, then found an electric drill, attached a thinnest drill bit, clamped the fangs with pliers, and tried to punch holes in the root of the teeth.

The three of them tried more than a dozen times in turn, and more than 20 fangs were drilled, but they didn't succeed once, and He Jun almost gave up.

In the end, he gave up the rough method of fixing the teeth out of thin air with pliers, first made a hole in the wooden board with an electric drill, stuffed the root of the canine with the root facing up, and then used the pliers to clamp the root of the tooth exposed, so that the canine was firmly fixed, and then it was much easier to drill the hole with an electric drill.

However, this is only the first step, and the next step is how to attach the drilled fangs to the arrow.

The drill bit is a little thinner than the chopsticks head, and the chopsticks are difficult to stuff in, He Jun had to cut the chopsticks head a little thinner, but the human hand is not a CNC machine tool after all, and it is difficult to cut the chopsticks head properly.

Fortunately, Douzi suddenly remembered that there were two buckets of super glue in the kitchen cabinet, and the chopsticks were coated with glue and then stuffed into the hole behind the teeth and buttocks, which solved the fixed problem.

Seventy or eighty fangs, less than fifty of which have been successfully mounted on the arrows.

And that's not all, because the diameter of the arrowhead is thicker than the chopsticks, and the chopsticks loaded with the arrows can't be loaded into the arrow path of the crossbow at all!

The three people who had been busy for most of the day were all dumbfounded when they saw this scene.

The solution is not nothing, one is to shorten the length of the crossbow body, as long as the crossbow body is shorter than the chopsticks, when the arrow is loaded on the crossbow bow, the arrow will naturally fall in front of the crossbow body.

But the crossbow body is short, and the rubber band used for firing must also be truncated, which will greatly affect both the range and the power, which is nonsense at all.

If you can't work on the crossbow, you can only think of a way on the arrow.

The length of the arrow is still shorter than the crossbow body, and then add a chopstick, which makes the arrow longer than the crossbow one more piece, and solves the problem that the arrow cannot be pressed into the arrow path.

However, each arrow required at least three chopsticks, and several people had to search through the unmanned houses to find dozens of chopsticks, which was enough to meet the needs of the modification.

It is not difficult to use a single chopsticks as a crossbow arrow, but it is not the case with several chopsticks to catch together, a qualified crossbow arrow, first of all, to ensure that the arrow body is straight, otherwise it is difficult to ensure accuracy after shooting.

For this reason, the three of them had to experiment again and again, leaving straight ones and tearing them down and redoing them if they weren't straight.

A large roll of scotch tape quickly ran out, and I had to run downstairs again to scavenge for scotch tape.

Luckily, it's a very common daily commodity.

Not only has the length of the arrow changed, but in order to ensure the stability of the arrow's flight, He Jun also increased the area of the arrow feather.

He didn't know the best ratio of the length of the arrow to the area of the arrow feather, it was said that he should conduct several experiments to find out the best ratio, but first, he lacked the corresponding knowledge, and second, he was reluctant to get the beast teeth in his hand, anyway, the range of the crossbow was only a few tens of meters, even if the arrow feather was too large, it would have an impact on the range, that is, three meters and two meters, so He Jun was not willing to spend that effort.

However, in order to minimize the effect of the increase in the length of the arrow, he added a pair of arrow feathers in the middle of the shaft, hoping to increase the stability of the crossbow arrow when flying.

He didn't know if it would be useful to do this, but he thought that the missiles always had a few wings in the middle and a few wings on the tail, so it should be of some use.

In fact, he would have liked to get some feathers to use as arrow feathers, but he was just thinking about it.

Although He Jun doesn't know much about the evolutionary trajectory of prehistoric creatures, he at least knows that the sky in the age of dinosaurs was controlled by pterosaurs, and pterosaurs flew by wing membranes like bats, and they didn't grow hair at all!

After so many days, except for the super-large insects, there are no other creatures in the sky, if there are pterosaurs here, it is impossible not to see one, so He Jun boldly judged that the time of the community crossing is likely to be the early days of the dinosaur era, and the pterosaurs have not yet evolved, so they have to die to find feathers as arrow feathers.

By the time the last arrow was refitted, the sky was already full of red clouds, and the three of them worked hard for a whole day without sleep or food to complete the forty-seven beast tooth arrows.

In addition, there are more than 100 scorched arrows made of single chopsticks - the so-called scorched arrows are sharpened and burned.

Looking at the dozens of long arrows and hundreds of short arrows lined up, the three tired people were full of a sense of accomplishment.

Awkwardly shook his sore and swollen wrist and sighed: "It's finally over, I'm almost hungry." ”

He Jun waved his hand: "Go back to eat, the glue will definitely dry tomorrow morning, and the time is just right." ”

Douzi was slightly stunned: "Brother He, do you mean that we will go hunting tomorrow?" We made so much jerky yesterday, enough to eat for a while, right? ”

"Then you can't sit and eat empty, right!" He Jun stretched his waist vigorously, "We must save more food, and besides, eating meat for a long time will definitely lack nutrition, so we have to find a few edible wild vegetables or wild fruits or something." ”

"Yes, yes, I have seen in the novel that the ancient nomads especially needed tea, just because they always ate meat, they must be consumed with tea, otherwise they will definitely get sick after a long time!" Beans agreed.
