With bearings, it is relatively simple to make axles and wheels, and you can directly shape them with bamboo.

But because he was worried that the bamboo axle was not strong enough to withstand too heavy items, Bai Yuqi had to mold the bamboo axle into a solid shaft with the thickness of a fist.

The wheels also had to be thickened and widened because of the lack of rubber, and they ended up being as round and bulky as the tires of a car.

To put it simply, this thing is ugly and crying, like a thick barbell with a whole body of turquoise.

However, because of the relationship between bamboo fibers, the axles and wheels have good elasticity and toughness, and they will not be so easy to break.

The service life is not expected, and the wheels made of bamboo can be counted on how wear-resistant they are, so they can only be used as consumables and replaced after a period of time......

System Projection: [Suggested Activation Spell: [Vajra];]

Well, the Eternal Endless System always comes up with some unscientific spells to recommend to him.

[Vajra] is similar to [Steel Lithography], which increases the strength of rock, except that it increases the strength of wood, making wood as strong as steel, but still maintaining the characteristics of wood.

The effect of this spell made Bai Yuqi stunned for a moment, and he was suddenly stunned by his own association!

Because, the effect of this spell is probably the most useful of the skills he has activated so far!

Think about it, it has the weight of wood, but it has the hardness of steel...... So what else does he do with steel?

If he had activated this spell earlier, he would not have used iron to make grid armor for Yu Chi Baolin before, how good would it be to use wood directly?

The same volume of wood is more than ten times lighter than iron, which means that if the ten-kilogram "Steel Scale Dragon Pattern Armor" just now was made of diamond wood, it would weigh less than one kilogram!

Armor of this weight can almost be described as light as nothing when worn on a warrior's body!

And because the weight of the material was reduced, why did he go to great lengths to design a hollow grid pattern armor?

Moreover, the effect of [King Kong Wood] can still be enhanced with the increase of the level and the characteristics of the material itself!

In that case, how hard would it be to use natural iron birch, which is twice the strength of steel, and the characteristics of the [Vajra] spell?

Upgrade [Vajra] to the top ...... again Isn't it going to be a diamond?

Shaking his head, he shook off the brain hole that he couldn't cover again, Bai Yuqi felt that the coffin board of the materials science bigwigs was almost unstoppable, so it was better to study how to make wheels.

With [King Kong Wood] and [Wood Plastic], Bai Yuqi gave up the "impractical" iron material and directly used bamboo to shape a heavy truck...... of the carriages.

Then looking at the "King Kong Bamboo Heavy Truck" that was pulled up after being tied to a few horses, he couldn't help but fall into silence, he felt that Datang's science and technology tree seemed to be taken by himself to a feeling of no return?

What about the route of the traverser who burns glass, burns cement, and boils soap?

Glass was solved by [turning sand into glass], soap was replaced by [cleaning], [deodorization], cement...... Why do you have one-piece molding [turning mud into stone] and [stone plasticing], and you still need a hairy cement? No matter how fast-drying cement is, is there a stone that directly turns into granite?

Stopped the "King Kong Bamboo Heavy Truck" that was dragged around by several elated Qianniuwei with war horses.

After Bai Yuqi checked and found that everything was in good condition, the front of the car with the front windshield was inlaid with a metal logo of "Bamboo Kamala", which can be regarded as a tribute to its predecessor "Motorcycle Mule".

Yes, you read that right!

Bai Yuqi used "King Kong Bamboo" to create this "Bamboo Kamala".

In addition to being covered in green, the shape is exactly the same as the 60-ton heavy truck used to transport ore in later generations!

Not to mention the front windshield, even the cab, steering wheel, brakes and shock springs, after all, he was modeled according to the structure of the truck searched by the system.

The only difference is that this "bamboo truck" is not as precise as the heavy trucks of later generations, it is just a vain thing, and the turning is hard broken by the driver......

So just after building a one-to-one restoration of the "model figure" of a heavy truck, Bai Yuqi gave up this meaningless brain hole product, and instead made simpler and more practical tricycles and four-wheeled vehicles.

On the one hand, let the displaced people carry the squeaky bamboo rat cage onto the bamboo card, and let Qianniuwei drive back to Kuyu City, and then bring more livestock.

Bai Yuqi hurried to shape more human-powered tricycles, so that a group of homeless people began to learn to pedal, and when they learned to move the cut bamboo onto the car and drag it back.

But just when he was busy working, he suddenly found a large group of craftsmen who were still holding all kinds of carpenter's work tools in their hands, all of them looking at him with dull faces, and Bai Yuqi remembered that the bamboo planks they made seemed to be useless.

Well, he seems to have accidentally robbed the craftsmen of their work.

But what can he do? He is also desperate! As soon as the brain hole pops up, he can't hold it down, what can he do?

In order to appease the craftsmen with despair in their eyes, probably thinking that they were going to lose their jobs, Bai Yuqi had no choice but to disassemble the three and four wheels into parts and throw them to study by themselves, to see if they could be imitated by hand.

As large areas of bamboo forests were cut down, large groups of bamboo rats and rabbits were captured, a large number of tricycles were made, and a large number of bamboo vehicles were dragged away by trucks and carts, the sky began to gradually darken.

Bai Yuqi saw that the time was not early, and was about to announce the end of the work and continue tomorrow, when there was a sudden commotion on the mountain.

Bai Yuqi, who thought something was wrong, was looking around, and Yang Tieniu ran back excitedly and shouted: "Big lord! Big lord!

"Flower skin?"

Bai Yuqi was confused: "What is it?"

"It's a kind of bamboo bear, but the meat is delicious, and the price of the skin is high!"

"This kind of bamboo bear has a much warmer temperament than a blind bear, as long as it doesn't provoke it, it generally doesn't bite. ”

Yang Tieniu said happily: "In the previous dynasty, there were still big families who raised them to play, and they were obedient when they gave them some food, but they were more than raising bamboo civet meat, and they could live by feeding some bamboo!"

What do you say?

The more he listened, the more Bai Yuqi felt that something was wrong, and threw down the work in his hand and ran up the mountain.

When he ran to a place surrounded by a group of mountain people, he opened the crowd and got into it, and couldn't help but burst into a foul mouth: "! Isn't this a national treasure?"
