With a trap made of rope, it can greatly reduce the head-to-head confrontation with the prey, reduce the probability of injury and even death, and can greatly improve the success rate of hunting.

The promotion is certain, Wang Yang took them in every day for the next few days, and let them watch the operation process over and over again.

Even defy the law, walk into the trap and let them pull themselves up.

They learn it very quickly, and it doesn't take much effort to get it.

Now they can take a team with a wooden spear and continue to use the drive tactic, while the other team uses a rope trap.

The team with the rope tends to have more stable access to prey.

It is very necessary to make another net.

But Wang Yang gave up this plan for the time being.

After all, if you pick plants again, you will get someone else's territory, and the dire cat is definitely not happy.

Wang Yang tried, and when he went up the mountain again, he was chased and intercepted by a dire cat.

And now the amount of food obtained is really a bit large, two days a day, fruits and meat are not easy to preserve, except for air-dried, often rotting.

Wang Yang was quite speechless, once the productivity came up, he felt that the population was insufficient.

The population is indeed not enough for today's development, adults have to hunt, and the friends are slowly cultivating the orchard, and the progress is slow.

Picking plants, taking fibers, rubbing ropes, and a series of other tasks have to be done by themselves, and they are very busy.

I don't have time to study other things, such as the big logs that are getting more and more full in the canyon, so I have to find some way to use them.

It is not practical to build a house, it is impossible to build a wooden ox and a horse, and the research on catapults seems to be useless in a forest full of large trees.

The bow and arrow can be thought of, now you can catch the wild boar, the tendons on the wild boar can be used, strengthen the bow body, the bowstring is forgotten, and the elastic material cannot be used.

But asking him to cut off a small part of the bow body from a large tree more than ten meters high is too time-consuming, and he will not spend time on it for the time being.

What we need to do now is to make a few more nets and eat as much as possible, even if it is wasteful.

It's a big deal if the meat is rotten, and it's a big deal to feed the saber-toothed tiger.

The population is still too small, and even though adults try to create people in their spare time, it still seems too slow.

Wang Yang thought about it for a long time and decided to improve the existing tool first--the fire tool.

As we all know, animals are afraid of fire, holding a fire stick in their hands, which has a great deterrent effect on them, and it is particularly important to study a tool that is easy to carry and can quickly make a fire.

Before, there was no rope, and it was not easy to develop, but now with rope, it can develop colorfully.

For example, taking fire, it was artificial fire before, relying on a pair of hands to rub hard, without half a point of skill, tired and half dead before giving birth to some sparks.

There are thousands of ways to do it.

For example, the Li people drill wood to make fire, find a bent branch or wooden stick, tie a rope at both ends, and turn it into a small thing similar to a bow, and then use the rope to wrap the wooden stick for fire around a few times, pull back and forth, and the wooden stick will automatically rotate.

How do you describe this thing? Erhu everyone knows, that scene is like pulling an erhu.

Wang Yang really wanted to try to pull the erhu, but unfortunately he lacked a pair of black glasses.

He decided to use the Iroquois method of fire.

The efficiency of this method of making fire is so high that it can be called a classic of the Stone Age.

It's also quite easy to make.

Drill a hole in the tip of the stick that made the fire, tie two ropes through it, tie a knot, wrap it around the stick, and wind it down.

Then take a small wooden strip, chisel the left, middle and right three holes, the wooden stick passes through the middle hole, the two ropes wound through the other hole, and then knot and fix.

When it is made here, a semi-finished product is formed, and this semi-finished product is actually ready for use.

The hand is placed on the wooden strip with three holes, and when it is pressed down, the rope is pulled and extended downward, and the stick is wound, and the stick will rotate rapidly due to the winding.

And due to the drive of inertia, the rope that was originally wound to the right has become wound to the left, and the wooden bar will automatically rise, and the fire maker only needs to easily keep pressing down to get it.

Wang Yang remembers that when he was a child, he had a toy, and when he pulled the rope one by one, the rope would make a whirring sound, and this principle was used.

Of course, the reason why it is said to be a semi-finished product is that it lacks an accelerator, without which the force of inertia will be much weaker, and it is difficult to achieve the ideal easy press.

The accelerator is also very simple, it is a small round wooden block one centimeter thick.

It took him almost a day to finally make a decent tool.

It was already dark, and the adults brought back today's prey, another sturdy wild boar.

The little friends happily gathered around the adults, watching the wild boar's eyes shine, as if they had seen the fragrant barbecue, and their eyes were wide and drooling.

The friends went to get the net very novelly, but the expelled person seriously pushed it away, and carefully held the net in his arms, for fear that the child would break the net.

Wang Yang was amused by the scrooge's actions, and he was very happy.

With prey, it is natural to need to slaughter and make fire.

He took the stone knife and cut the boar's skin with difficulty, making room for him.

He tried to remove the skin as intact as possible, then cramped and finally started a fire.

The work of starting a fire requires the cooperation of two people, and it is often his parents who do it.

This time was no exception, his parents took out the fire tools and prepared to make a fire.

He took the tool he had just made, crouched to the side, and then screamed a few times, drawing everyone's attention.

Everyone walked over, looked at him, and then looked at the new fire-making tool, and understood that Wang Yang had made something new again, and looked at it very carefully.

Wang Yang and his parents started to light a fire at the same time, and he wanted to make it clear to everyone that the new tool could be used by one person and was more efficient.

He began to press down, the stick was driven by the rope, rotated, then drove the rope, pulled up the wooden strip, Wang Yang pressed down again, rotated again, and pulled up the wooden strip again.

The friction sound of "whirring" sounded quickly, and the wooden stick spun faster and faster, without stopping.

And on his parents' side, every few minutes, they have to change someone to continue to ensure continuous friction.

Ten minutes later, green smoke rose from Wang Yang's fire-making tool, and everyone stared with wide eyes and watched incredulously.

Seeing more and more green smoke and faster rotation, Wang Yang's parents directly stopped the action of making fire and stared at the tool in a daze.

"Zizi" a little spark splashed from the notch onto the dead leaves, and then more sparks splattered out.

Wang Yang's mother hurriedly covered a pile of hay, and it didn't take long for a flame to burst out quickly, reflecting on everyone's dull faces.

"Whew~ It's so fast, it should have shortened the time by at least half." Wang Yang stood up, very satisfied.

"Woo~" Everyone shouted in ecstasy, and they all squeezed up to try it, and several friends were squeezed down, still stubbornly squeezing from the adult's crotch.

If you want to say that the fastest is still the chaser, he squeezes the others away, and with a leap of fish, he holds the tool in his arms, no matter how many people pull him.

Wang Yang smiled dumbly, this guy is really a miser.

(The second update came out, a little late, but it was a good start, and I tried to keep it up.) ）
