There is no doubt that there will be snake meat today, although this python is said to be very large, there must be more than 100 catties, but the tribe is now 500 people evenly divided, it is not enough to see. In Ye Feng's opinion, the urine sex of the cooking team led by Chu Yun would definitely make a hodgepodge of snake meat and other meat, thinking that he was eating a delicious piece of meat, he spit out a snake meat and appeared in his bowl, that scene, Ye Feng couldn't help but shudder.

In the end, Ye Feng still opened a small stove by himself, braised wild pheasant, well, it tastes good.

Early the next morning, the guy from the root of the tree took people without even saying hello, and went to the tin mine early in the morning with a mammoth.

Ye Feng was very helpless, it seemed that he was going to reduce the burden on them, and the only way he thought of was to build a car.

It wasn't until he started building cars that he realized the difficulty of building cars. He is very envious of those characters in the crossing, they are also traversers, either they know astronomy, geography, or they are goldfingers and all kinds of hanging. And he was stumped by an inconspicuous broken wheel.

Yes, you heard it right, it was the inconspicuous wheels that became the obstacle of Ye Feng's car. Making a wheel was still a high-tech product in the feudal era, let alone this primitive and barbaric era.

This is undoubtedly a big shame for the thousands of crossing troops.

It is said that "the wooden straight rope is a wheel, and its curve is in the rules." The ancients explained the manufacturing process of wheels in just 12 words, but Ye Feng returned all his knowledge to the teacher, and wanting him to build that kind of wheel with spokes is tantamount to letting him ascend to the sky.

If he didn't know who the first person to make the wheel was, otherwise Ye Feng would have thrown himself to the ground with the five bodies that that person admired, just because it was so difficult to build a wheel!

Ye Feng thought about it, and felt that he still gave up the spoke wheel, so he found a round tree, cut it into round pieces with a saw, and used this kind of round piece to make it at once.

As a wheel, it was not only under the pressure of the body, but also the heavy goods on the body, so Ye Feng took a dozen heavily armed warriors into the primeval forest.

Soon, they found a large tree with a round trunk, and without saying a word, picked up an axe and cut it down. By the time I returned to the tribe with the tree, it was already dark, and I had to drag it out until the next day.

Early the next morning, Ye Feng began to prepare to make a vehicle, found a few pieces of animal skin, drew the appearance of the carriage, and handed it to the clansmen of the industrial team. The production of the carriage is very simple, it is nothing more than putting together pieces of wooden planks, and he doesn't need to worry about this level.

The industrial team began to be busy, because there was not enough wood, and Ye Feng brought back wood to make wheels, so they had to go to the forest to cut down trees first.

Ye Feng made solid wood wheels, which were much simpler than spoke wheels, Ye Feng held a saw, and compared them back and forth with the bark of the wind trunk.

"How thick should I cut it?" , the saw in Ye Feng's hand has not been able to get his hands down. If it is thin, the wheel will break because it is overwhelmed, but if it is too thick, it will be too heavy to pull the car.

Ye Feng weighed it again, and finally decided on a wheel with the thickness of four fingers to try it first, if it is too thick, just change it in the future, anyway, in the forest, there is a lot of this kind of wood.

After some busyness, Ye Feng made two wheels, he planned to build a two-wheeled vehicle, although the four-wheeled vehicle has more load, but the most troublesome thing about the four-wheeled vehicle is the steering problem. With Ye Feng's current level, it can't be solved for the time being.

As for the superiority of four-wheeled vehicles and two-wheeled vehicles, it is a matter of opinion.

Chinese carriages have been developed for thousands of years, but most of the carriages commonly used are still two-wheeled vehicles, which shows the applicability of two-wheeled vehicles in China.

After the wheel was made, Ye Feng was ready to make the axle. Since the axle carries almost all the weight of the car, ordinary wood is definitely not enough, and hard materials must be used.

But which material to choose? Ye Feng was puzzled, and couldn't help but turn his gaze to the wood used to make wheels.

Ye Feng didn't know what kind of tree this was, the texture was very hard, he worked very hard when he processed it, after sawing off two wheels with a saw, Ye Feng's hands had two blisters, and several of the sawtooth broke off.

It's decided, it's you! Ye Feng called a few warriors and re-entered the forest. The tree was too thick and had to be processed to the right thickness. However, with the current technology of the tribe, it is not possible to manually machine straight and round axles. I had to step out of my feet and look for the tree in the forest that met the requirements.

Coincidentally, as soon as I entered the forest, I encountered the industrial team returning from logging.

"Yo, you're done?" , Ye Feng greeted them.

Someone in the crowd replied, "Yes, Ye Feng, you are?" ”

"We're looking for wood for this tree! Have you seen it when you were logging? Ye Feng said, and took out the blades of this wood and showed them it.

The man stretched his neck to take a look, nodded and said, "This kind of tree, we saw it just now, and we cut it a few times in the place where we cut the wood, but it was too hard, so we didn't bother to cut it." ”

"How many of these trees are there?"

"There are many, some thick and some fine."

Ye Feng breathed a sigh of relief when he heard this, he thought that he would spend a lot of time looking for this kind of tree.

The last two teams staggered by, and before parting, the man turned around and said to Ye Feng: "By the way, Ye Feng, there is a black bamboo there, do you know what this thing is?" ”

Black bamboo? Ye Feng had never heard of it, so he naturally couldn't answer it, and said to him: "I haven't heard of what you said, I'll go and see it when the time comes!" ”

The man nodded, and the two teams officially separated.

Following the footprints left by the group just now, Ye Feng and his party found the place where they were logging.

As soon as they arrived at the place, Ye Feng found the kind of tree they were looking for.

Sure enough, this kind of tree is large and small, and it grows densely in a large area.

Ye Feng hurriedly stepped forward, and it didn't take long for him to find the kind of tree that met their requirements.

"Do you want to give this tree a name?" Ye Feng is very positive about naming something.

This kind of tree is so hard, let's call it ironwood, right?

Then he gave up on the idea.

Because in reality, there is a kind of tree that is also very hard, but it grows completely differently from this kind of tree, and it is called ironwood.

No, you can't have the same name!

Well, let's call it "Jianmu"! Take the meaning of hard.

Ye Feng admired his talent more and more, and immediately told those soldiers what he thought.

The warriors clapped their hands and praised without thinking about it, in their opinion, all of Ye Feng's words were the truth.
