Needless to say, the purpose and importance of fire, all the adults in the clan have learned to drill wood for fire with Lyle.

Because in this era, there are no 'witches' who pretend to be gods and fools around, and there is no old bastard with rhythm, drilling wood to make fire is fairly regarded as a life skill, and Lyle is just the person who invented this skill, not a 'god son', so naturally he can't suddenly become the number one person above the leader.

However, Lyle's elevation within the group is still an inevitable consequence, most notably from the change in the priority of eating. The original feeding priority was [Leader> Young Strong> Children > Old People], but now Lyle has advanced one level, the same level as Young Zhuang.

No one has a problem with this at the moment, and even if Lyle looks at it as a mischievous bear child who likes to play with vines, tear bark, mud, and wood, they still have a lot of gratitude in their hearts. But humans are forgetful creatures, and the people can't always remember this feeling, and one day, they will see Lyle as an ordinary ordinary person, and it will not be until Lyle's death that he will remember his exploits and use them as materials to educate the next generation to work hard.

- It was supposed to be this development.

"Lyle, what's on your feet?" The adults, led by the leader, surrounded Lyle, who was running around the cave in straw sandals.

Lyle was confused: "This? Vines, I just peeled off the outer layer of skin. ”

The leader shook his head and asked, "I know it's a vine, I'm asking you what you make of a vine?" ”

"Uh, what's on the bottom of your feet?" Lyle asked, tilting his head.

I don't know if Lyle was the first person in the world to invent shoes, but he was definitely the first person in this group, and he had the naming rights for shoes, but it was clear that he didn't think of a name before anything was made.

The leader exchanged glances with the people around him, and everyone was puzzled, "What is on the soles of your feet?" Show me. ”

"Oh......" Although he was reluctant to think about what he had been thinking about for a long time, the leader spoke, and Lyle could only take off his straw sandals and hand them over—these straw sandals were obviously not delicate, but they were made of a layer of rattan soles, and then a rope twisted from the fibers torn from the inside of the bark was threaded through the gap to make a 'flip-flop' pattern.

But where had this group of primitive people, who were still using stone tools, seen such a thing, and looked at it over and over for a long time, and let out an exclamation from their mouths because they could not find the words to describe it.

"Lyle, is this thing any good?" The soles of primitive people's feet have been honed with thick calluses since childhood, and it is not a matter of climbing mountains and mountains, but there must have been the experience of being pierced by the spikes of various plants, and being pricked by insects that have not been noticed, and the leader can easily guess the invention intention of straw sandals.

Lyle said honestly: "It's not easy to use...... It feels weird when I walk, and I can't walk fast outside. ”

"What are you doing that?" The child who was watching outside asked everyone in the cave.

"If you don't make it, how do you know it's not easy to use." "And if you can give me a small piece of animal skin, I can wrap my feet in a leather while I wear my shoes...... Wouldn't that be useful? ”

He can play with vines, but he can't cut large pieces of animal skins into small pieces to 'waste', or he won't be beaten to death by his mother.

“……！” Everyone suddenly realized.

There is no such demand in other seasons, but when you nest in a cave in winter, you can have such a pair of animal skin socks + straw sandals, which will undoubtedly help keep warm.

"Lyle, can you teach me?" In this era, practicality is paramount, and when straw sandals are still useful, someone immediately asks for it.

"Of course." Lyle nodded in agreement, as long as he didn't make a pair of straw sandals for all the members of the clan, it wouldn't be fun at all, "But the vines have run out, and the bark is still there." ”

"That's easy!" Immediately, someone went out to look for materials in a hurry.

"Hey~" Lyle was stupid, he knew that he had a lot of vines to play with, no matter how he thought that the adults would bring back the vines that were more than three or four times the demand, after all, this thing was not difficult to find.

But.

"............" Lyle didn't notice that several adults in the group were watching him, including the leader.

These adults finally realized one thing—Lyle was different.

——————————————————————————————

Four days later, Lyle weaves a straw skirt for herself, but after wearing it for a day, she dislikes it and throws it away, and is picked up by the child Ami and walked everywhere to show off.

A week later, Lyle made himself a straw hat, but threw it aside because it was uncomfortable to press his hair.

Half a month later, Ah Ping casually took a draft hat to hold wild fruits, and Lyle had an idea and weaved a large rattan Kuang.

A month later, because Lyle accidentally fell to the ground while walking around with Fuji Kuang in his arms, he improved a Fuji Kuang that could be carried behind him.

…………

In fact, after Lyle demonstrated the use of tree vines, tearing fibers, rubbing ropes, and tying knots, many people in the group entered a situation of 'drawing inferences' and investing time in new technologies when they had nothing to do, some researching how to weave other things, some researching other ways of tying knots, and some researching the use of rope on bone and stone tools.

Although their brains are not well developed and they are not educated, they do not have an IQ of 0 after all, and they can take a few steps forward as long as there are pioneers to show the way.

However, the results of their efforts do not seem to be able to catch up with the results of Lyle alone, for example, Ah Keung, who has long wanted to weave a container, is trying to make it concave on a flat woven board, and Lyle, who has been playing with mud outside, has been weaving rattan Kuang in two days.

Now, not only the more intelligent adults such as the chieftain, but even the children realized how extraordinary Lyle was...... Fortunately, in the primitive race that is tied by blood, this super-standard 'excellent' will not bring any disaster to Lyle, and everyone expects Lyle to continue to bring new things and make life easier.

Others are just meaningless 'expectations', but the leader has a 'practical measure' - to let Lyle's mother take good care of her son.

Of course, this does not mean that Lyle's mother only needs to be a bodyguard from now on, and the primitive people do not have so much labor to waste. While Lyle squatted by the creek to watch the fish, she was going to fish; While Lyle is playing in the mud by the creek, she has to find stones that can be used as tools; When Lyle wants to wander around the cave, she collects firewood for wild fruits.

Even after the advent of the back-mounted rattan for several months, Lyle did not make any new inventions, and seemed to be addicted to the game of playing mud and rubbing mud balls into the campfire, and the leader did not reprimand him, let alone remove Lyle's mother's bodyguard work.

It turns out that even miraculous geniuses need the right environment, and providing the right environment for geniuses is a decision that a qualified leader must make.

"Here, here, Mom, just put it here." Lyle, who had run back from outside, shouted at his mother.

"You kid...... How to play mud and play in a cave. Lyle's mother carried a rattan basket of wet clay into the cave and lowered it at the designated location.

"Because this time it's going to be a long time to play~" Lyle's eyes flashed with excitement on his hands and body.
