Soon, a crude stone axe was completed with the cooperation of Han Che and Mo Lan!

"Actually, this axe can be made a little more delicately, but we don't have that much time right now, so we can only make it simply!"

Mo Lan took the stone axe, weighed it repeatedly, and then nodded.

"This is the axe?"

With a hint of curiosity on her face, Jinyu stepped forward to look at the axe in Mo Lan's hand.

"Yes!"

Mo Lan nodded and explained, "The axe is a labor-saving logging tool made using the principle of lever balance. And the equilibrium condition of the lever is that the power multiplied by the power arm is equal to the resistance multiplied by the resistance arm. ”

"Let's see, the axis connecting the axe handle to the stone and wood is the power arm, and the axis to the stone blade is the resistance arm. The force we exert when we cut down trees is the motivation, and the obstacles we get to the trees are the resistance.

When the power arm is larger than the resistance arm, the tool is equivalent to a labor-saving lever, and the axe is exactly that. That's why I made the handle of the axe relatively long, because only the long power arm will save effort, and if it is short, it will become a laborious lever, and using it to cut down trees will be more cumbersome than a stone knife! ”

Mo Lan probably talked about the principle of the axe, and saw that everyone understood less and confused more, and he didn't care, because these physical knowledge is inherently complicated, even if they have some wisdom, it is not easy to figure it out for a while.

But it doesn't matter if you don't understand it, just let them know that cutting trees with an axe is faster and easier than a stone knife!

She glanced at Jinyu and saw that he seemed to understand something, so she continued.

"As for the principle of changing quantities, it is better to understand! Because the axe is in the shape of such a right angle, when we hold the handle and cut down the tree with force, the force I exert on the handle will pass through the handle to the stone blade, and then it will be converted into the cutting force of the stone blade on the tree! And this force remains constant in transformation, which is called the principle of the amount of change. ”

"Because the axe conforms to these two principles, it will be very labor-saving, at least half the effort of the stone knife! Because the stone knives are made of stone as a whole, they are bulky and unusually heavy, and the axe handle is made of wood, which is easy to grasp and lightweight, which is the advantage of axes to cut down trees! ”

After Mo Lan finished explaining, he looked at the snow ape clan's dazed clansmen and said with a smile: "I know you may not understand these things, but let's experiment and know how effective it is!" ”

After that, she turned to Jinyu and said, "Patriarch Jinyu, you might as well send someone with great strength to compare with me to see if this axe can beat the stone knife!" ”

Hearing this, Jinyu nodded and said, "It's okay!" This way everyone will understand a little more! ”

After that, he raised his hand to the crowd and said, "Labta, you come out and try it with Miss Molan!" ”

A man with a tiger's back in the crowd walked out and said to Jinyu: "Yes, patriarch!" ”

Mo Lan also turned around and said, "Minister Lan, you are working hard, just show your friends of the Snow Ape Clan casually!" ”

Lan Qiao was stunned for a moment, then walked over hard, glanced at the sturdy man with his back to everyone and whispered, "Miss Mo Lan, can I do it?" That man is so much stronger than me! ”

Mo Lan glanced at the strong man of the Snow Ape Clan, isn't it? That block is worth two blue joe!

She chuckled, but looked up and said, "Don't you believe me?" When did you trap you? Go with confidence and boldness! I'll take it if I lose! ”

Lan Qiao was embarrassed, and then turned to Narabuta and smiled: "Please! Friend! ”

Stretch out your hand and don't hit the smiling person, you will be polite for three points, and you won't lose if you lose! This is taught by Mo Lan, Lan Qiao remembers it clearly!

Labuta glanced at Lan Qiao's thin little body, and said disdainfully: "It's just you, I think you still admit defeat!" ”

"A soldier who surrenders without a fight, the best strategy! However, if you don't reach the realm, don't be rampant! ”

Not to be outdone, Lan Qiao immediately ridiculed him, and said all the art of war that Mo Lan had taught.

As soon as he said this, Labuta immediately looked confused!

What does it mean?

Poof!

Mo Lan couldn't help laughing, and stepped forward to explain to Labta: "Well, what he means is that it's useless to say anything now, let's talk about it after the competition!" ”

When Raputa heard this, he immediately looked embarrassed. I don't even understand what people say, and they still talk nonsense!

"Yes, Minister Lan, you really are! Can't you say something that people can understand? As the head of the Flame Wolf Clan, how can you bully the small with the big? If you are literate and hyphenated, do you think that everyone is as illiterate as you? What a faux pas! ”

This guy's ability to add fuel to the fire is perfect, and he immediately made Raputa's face turn into the color of pig liver!

Seeing that the snow ape clan who originally disdained Lan Qiao, they immediately restrained their contempt for him, and they all looked ashamed and stupid.

This flame wolf clan is really Crouching Tiger, Hidden Dragon! I didn't expect an inconspicuous flame wolf clan to be so powerful! What a sight for them!

Jinyu didn't get annoyed when she saw this, but she stepped forward and said to Mo Lan: "The clansmen are ignorant, please don't worry about Miss Mo Lan and others, please!" ”

Mo Lan immediately took the opportunity to go down the steps and said, "Patriarch Jinyu is polite, please!" ”

Jinyu took the lead and walked forward, found two elephant fighting trees of similar thickness in the elephant fighting forest, and said to Mo Lan beside him: "Just these two shall prevail, how about it?" ”

Mo Lan looked at the two trees and nodded, "Yes!" ”

With a wave of his hand, Raputa, who was holding a stone knife, stood in front of the tree on his left. And Lan Qiao, who was holding the stone axe, immediately stood to the right when he saw this.

"Let's get started!"

As Jinyu spoke, Labuta and Lan Qiao waved their tools at the same time and began to cut down the elephant fighting tree.

At first, there was nothing out of the ordinary, as if Labuta had the upper hand because of his strong size and strength.

This situation immediately caused a commotion among the Snow Ape Clansmen.

"Labuta has won!"

"Dare to despise my people, don't measure yourself!"

"It seems that their tools of the Flame Wolf Clan are not very good!"

Lan Qiao couldn't help but be a little anxious when he saw everyone talking, and swung the stone axe hard to cut down the trees, but at this time, Mo Lan came over and reminded: "Don't worry, just cut slowly!" Remember, focus on one place to cut! Don't cut it in the east and cut it in the west! ”

Lan Qiao nodded, wiped his forehead, clenched his axe, and continued to cut steadily and forcefully.

Just when the voices of everyone were talking one after another, Labuta began to look weak!

Not only was he sweating profusely and panting, but the force of slashing at the tree trunk was also significantly weaker by more than half!

On the other hand, Lan Qiao is still unhurried, his strength is neither light nor heavy, and even his forehead only has a thin layer of sweat!

This comparison, in fact, has seen the gap between stone knives and stone axes. But Raputa gritted his teeth and refused to admit defeat, and launched a fierce slash at the trunk of the tree!

Mo Lan glanced at it and sighed secretly, Rabta's strength was in vain! Cutting a tree in a mess, the uneven cut marks up and down are just cutting off layers of oak bark, and it can't shake the oak tree at all!

And over there, when Lan Qiao cut down the tree to three-quarters, Mo Lan said loudly: "Okay, Lan Qiao, no need to cut it!" ”

Lan Qiao stopped his hand, looked at Mo Lan and said, "I haven't cut it yet!" ”

Han Che stepped forward to explain for Mo Lan and said, "It's already broken, so you don't have to make any more effort to cut it!" ”

"Is it broken?"

Lan Qiao looked up at the elephant bucket tree still standing firmly in front of him in confusion, a little dizzy.

Was he dazzled? Isn't this tree still standing?

Mo Lan smiled, turned her head to Jinyu and said, "Jinyu Patriarch, is it still comparable?" ”

Jinyu glanced at Mo Lan, stepped forward and said to Labuta, who was already tired and had less than three points of strength left: "Enough! No need to compare! We lost! ”

"Patriarch, it's not fair! Usually cutting down elephant fighting trees, three people take turns to cut them, but now Labuta is alone, no matter how hard he is, he will be tired! ”

Seeing that the patriarch admitted defeat, someone in the Snow Ape Clan immediately shouted out unconvinced.

"That's right! That Minister Blue hasn't cut down the trees yet, so we're not losing yet! ”

"Labuta! If you work harder, you will definitely be able to beat him! ”

Someone started cheering Raputa on!

Raputa gritted his teeth, grabbed his stone knife and prepared to continue chopping.

But Jinyu waved his hand and said, "No need, Minister Lan has already cut down the tree!" ”

Labuta was dumbfounded, and pointed to Lan Qiao, who had stopped before he finished cutting it, and said, "Patriarch, his tree has clearly not been cut yet!" ”

"Who said it wasn't broken?"

Mo Lan immediately retorted, then took out a ball of yak tendon rope from the embroidered bag around his waist, tied a small stone to one end, and then raised his hand to throw it from the branch of the tree that Lan Qiao had cut down, and then shouted: "Lan Qiao! Come here! ”

Lan Qiao immediately threw down his axe and ran over.

"I shouted one, two, three, pull down hard, pay attention to the tree and run quickly, don't smash it!"

"Understood!"

Lan Qiao wiped a handful of sweat, nodded, and then stepped forward and held the yak tendon tightly with both hands.

"One, two, three, pull!"

With Mo Lan's command, Lan Qiao's hands were forced, only to hear the squeak of the tall elephant fighting tree, and he actually broke and fell to the ground!

Lan Qiao quickly dodged, and the elephant bucket tree fell to the ground with a bang and was completely cut down!

The audience was amazed!

All the Snow Ape people are speechless anymore! Because there is nothing to say!

A man who was half the size of Labuta actually cut down an elephant bucket tree that Labuta didn't even cut down with all his might?

What does this mean?

It shows that the stone axe in his hand is much better than the stone knife! This experiment is completely convincing!

Actions speak louder than words! The words in Mo Lan's mouth became a reality, and no one dared to question her judgment anymore!

At this moment, everyone's eyes were full of awe when they looked at Mo Lan again, including Jinyu!

At this moment, his eyes flashed with a strange brilliance, looking at Mo Lan's eyes, as if Mo Lan had become a divine existence like the most precious blood golden lotus in his clan!

Mo Lan put away the yak tendons, clapped her palms, walked up to Jinyu and said, "Patriarch Jinyu, you are lucky to live up to your trust!" I don't know if you have any questions, just ask them together! ”

Jinyu looked at Mo Lan, and there was a little more inexplicable meaning in her eyes.

He said, "In that case, you're welcome!" There are indeed still problems in my clan, please give me advice! ”

After that, as soon as he raised his hand, a woman from the Snow Ape Clan stepped forward and said: "Miss Molan, our clan needs to cut trees into thick and uniform wood to build houses, but after each split, barbs are growing on the wood, but we use grinding stones, which is laborious and time-consuming, and is often pierced in the hand, I wonder if Miss Molan can help us think of a way to solve this problem?" ”

Mo Lan smiled when he heard this: "This is easy to do, I will teach you a tool, specializing in barbs, it is absolutely effective!" ”
