After eating the food, Shen Nong slept a little, and then woke up under the call of the cang, since there was not much time to waste, Shen Nong washed his face a little, and then put himself into work with an urgent mood.

The first type of chariot is relatively simple and does not require Shen Nong's detailed explanation, and the clansmen can make it themselves, while the second type of chariot is difficult in terms of gear set devices and weapon systems.

Shen Nong had already told the four Cang people about the use and production method of the gears before, so they would be responsible for this aspect, and Shen Nong's task was to make weapons.

This weapon is not an ordinary weapon, in Shen Nong's conception, the chariot must be loaded with the kind of range strike weapon that is both ultra-long-range and full of lethality.

After a night of thinking, Shen Nong finally confirmed this weapon as a kind of ejection device similar to 'bowstring tensioning' by using a combination of gears and animal tendons, and then equipped with a bone spear handmade by the Huangqiu tribe themselves, so that it could form a spear launcher, and when multiple spear launchers were pieced together, it was exactly the range strike weapon that Shen Nong wanted.

With this idea, Shen Nong picked up the spear launcher design he had drawn last night and walked towards the big cave, where all the resources of the Huangqiu tribe were piled up in the big cave, and Shen Nong had to go there to find a suitable wood to use as a spear launcher.

In order to facilitate the integration of the spear launcher, the shape of the launcher must be made smaller, otherwise if it is too heavy when assembled together, it will cause inconvenience to the movement of the vehicle and become a drag.

"Witch. ”

"Wu!"

At this moment, the big cave is overcrowded, and everyone is searching for the materials they need, and basically every Huangqiu tribesman has their own task at the moment, which is to make chariots.

"Give me a piece of wood, about the length of a spear. Shen Nong said to the clansmen who were in charge of managing resources.

After a while, the other party handed over a square piece of wood, the shape of which made Shen Nong feel quite satisfied, and at the same time, he also admired the 'clear plan for the division of labor' he proposed to the people of the Huangqiu tribe before going to bed.

A bunch of raw materials need to go through multiple steps of processing before they can become the final accessories, just like the gears that Shen Nong proposed this time, if no one carves and chisels with a bone knife, the wood will definitely not be able to become the shape of a gear.

In order to speed up the efficiency, Shen Nong made the people of the Huangqiu tribe consciously divide into four groups, the men with great strength were divided into one group, went to the forest to cut trees, and the hands were flexibly divided into a group to help carve the wood into gears, and others could choose to join the group that processed the trees into wood, or the group that made the wood into chariots, so that everyone had their own work to do, and there would not be a situation where someone did not know what to do, but a certain job was performed by too many people.

After asking the clansman for a few tendons and five of the smallest gears, Shen Nong left the big cave and returned to the small cave where he lived.

Making a device that allows the bone spear to be launched is still very simple for Shen Nong.

I remember when I was a child, in the toy store opposite the school gate, Shen Nong once bought a plastic toy for 1 yuan a piece, the shape of this toy is a box-like cube, and there will be a long strip-like groove on the side of this box, children can buy the plastic disc that comes with the toy into this groove, at this time you will hear a "click", the plastic disc has been fixed in the box.

At this time, the user can press a button on the surface of the box, and the plastic disc will instantly eject out of the box, quickly flying out of the distance of four or five meters, which is quite interesting.

The principle of this device is very simple, it relies on several plastic gears to tighten a rubber band, and then uses the force generated by the rubber band to bounce off the plastic disc with the help of the force generated when the rubber band pops off.

Shen Nong just needs to do it like this.

The tendons in the beast's body are far less durable and elastic than those of the fierce beast, so Shen Nong took all the tendons that were taken out of the white-whiskered apes last time and then taken out of their bodies, so there was no need to worry about the quality at all.

"It's started. Shen Nong picked up his bone knife and sighed secretly, and then began to carve and chisel the other party's wood.

Although Shen Nong had not been engaged in the carpentry industry before, he could still chisel the wood into the shape he roughly wanted with brute force, and soon, a long wooden block with a concave shape appeared in Shen Nong's hand.

The center recess of this block is just right for the next Bone Spear, and it will be a bit wider than the Bone Spear, preventing the Bone Spear from getting caught in the dispenser itself when loaded and fired.

At one end of the wooden block, Shen Nong embedded a gear, and on the axis of this gear, there was a wooden bar connected to a bone hook, which was used to pull the animal tendons, and when the gear rotated, the hook would automatically pull back and enter the accumulation process.

When the full force is accumulated, as long as the hook is released, the taut beast tendon will instantly rebound because it is not controlled, and the bone spear pressed on the beast tendon will be ejected directly from the launcher, in general, it is still a relatively simple elastic deformation principle.

In order to quickly loosen the hook, Shen Nong also deliberately made a button on the launcher, as long as the bone spear is inserted into the launcher, the hook will automatically pop to the left, and when someone breaks the buckle to the right, the bone spear inside will instantly shoot out.

And when the bone spear is inserted into the transmitter, how much force can be stored by the animal tendons is judged according to how many gears you have installed on the transmitter, one gear turns in one circle, and the more turns it turns, the greater the force that will naturally be stored.

The two ends of the beast tendon were nailed to the section of the concave wood without a gear with the bone fragments of the white-whiskered ape, and Shen Nong pulled the middle of the beast tendon hard and buckled it on the gear at the other end, and now 80% of the launcher has been made, and the next thing to test is that the beast tendon of the white-whiskered ape can withstand the charging of several gears.

Shen Nong was naturally more greedy at first, and directly installed all five gears, but who would have thought that the bone spear had just been inserted into the launcher for half a half, and the taut beast tendons would break with a 'bang' in an instant, obviously unable to withstand the simultaneous accumulation of the five gears.

Shen Nong had no choice but to reduce a gear, replace it with a brand new beast tendon, and insert the bone spear into the launcher again.

This time, the situation was much more stable, the bone spear was directly and smoothly stuffed to the bottom of the launcher by Shen Nong, and the beast tendons were already tense to the limit under the simultaneous rotation of the four gears.

Seeing this, Shen Nong directly raised the launcher with both hands and aimed it at a nearby rock wall, and then flicked the wrench.

Shout!

In an instant, the bone spear that was waiting in the launcher shot out like a bolt of lightning, and slammed into the rock wall.

Bang!

With a crisp sound, the bone spear broke directly after hitting the rock wall, and fell to the ground in half, and there was an extra thumb-sized pit on the rock wall, which showed that the power of the launcher was really not small, if it was shot on a person's body, it would have to poke out a blood hole in an instant.
