Of course, it is not an outright "donation", but an acquisition.

In this game, most of the things have to be done by the player himself, and the system only provides methods.

The only things sold in the system are mounts, fashions, and horns, which are either model goods or auxiliary consumables, without any combat attributes.

Even the things in the system store, except for a very small amount that will be used for teaching at the beginning, everything else is bought back from the player by the system.

It means that the game company itself is a second-hand dealer.

NPC Tinkerers can be hired, but the materials have to be done by the players themselves.

So, right now, all the gangs in Minamino Castle – or any city in the game – are frantically grabbing all kinds of resources, especially wood and stone.

For a while, Luoyang paper is expensive, and there is no market.

Not just Shade Moon, but all other gangs are mobilizing players to donate.

In contrast, the price of Yin Yuekai is quite acceptable, and it is directly handed over to the gang warehouse with the "gang donation" function given by the system, and in addition to getting the gang tribute, you can also find management to receive money, which is 1.2 times the market price.

Not bad indeed.

But the resources on Mo Dou are too miscellaneous, and he can't take out just wood and stone.

He won't take it either.

Honestly going up the hill to chop wood is not the style of ink fountains.

And no matter how much you cut, it's useless, because you can't bring it back.

The resources on the ground of the gang, although they can't be moved, can look at the attributes.

The weight is too high.

The weight of any whole wood is more than 10, the timber of the girder is even 50, and the stone is even higher.

Chopping one, lifting one?

If you run, you will run to death.

And now the life players of the whole city are doing such things, and the competition is too great.

But among them, there is a lot of business opportunities.

To be a "life player", that's it, something has a high return, follow the trend to do it, although you can earn a little, but it's all shrimp.

At this time, you should go to the bottom business.

For example, with the rise of the live broadcast industry, everyone goes live broadcasting, and the competition is too great.

Reselling audio and video recording equipment, making a lot of money and making a lot of money, the price is as you shout, and some people buy it.

In this case, there are two kinds of underlying businesses.

First, make high-quality axes and pickaxes, novice axes, cut one in 10 minutes, I made one, cut one in 1 minute, and life players don't grab their heads?

Second, help move things.

The former is ironwork, the latter is carpentry, and the ink fountain with casting level 0 but carpentry level 8 is of course the latter.

The material load is so high, if you can make a carriage......

Deceptively simple.

But Mo Dou knew that there was a difficulty in making a working carriage.

Differential.

The biggest weakness of traditional horse-drawn carriages is the inconvenience of turning.

There is no problem with running in a straight line, but after rushing up, you can only hit hard all the way, turning = overturning.

The reason for this is that whether it is two-wheel drive or four-wheel drive, the wheels are connected by a crossbar, and the speed of the wheels at the left and right ends of the same crossbar must be the same.

But when cornering, because the body of the car is arcing, understood as a circle, the outer wheels go longer, and the inner wheels go shorter.

But when the wheels on both sides are tied together, the speed must be the same.

This system is unsustainable.

Obviously, if you want to force a corner, you can only exert a huge pull force, dragging the outside wheels on the ground to "slide".

There is also a premise that your car must not be very fast, otherwise the strong centrifugal force will cause the car to be thrown out directly.

Therefore, in the era of cold weapons, the "chariots" were generally two-wheeled and four-wheeled carriages, 99% of which were ceremonial vehicles, and more than ten or twenty horses pulled together, walking slower than people - because they did not dare to go fast.

When a four-wheeled car turns, not only the speed of the left and right wheels needs to be different, but also the front and rear speeds are different (the trajectory of the wheels on the same side is two concentric circles with different radii).

The fewer wheels, the easier it is to turn, so wheelbarrows are often used to carry materials.

The bigger the car, the more wheels, the more difficult it is to turn, and to a certain extent, it is also one of the important reasons restricting the development of human civilization - inconvenient transportation.

To overcome this obstacle, a differential is a must.

There will be a spherical structure in the middle of the rear wheel crossbar of the car, that is, the differential, in order to accommodate this thing, there will be a convex in the middle of the rear seat chassis of the double-row car, which of course cannot be for the sake of good looks.

The principle is actually very simple, vertical and unfixed planetary gears.

The middle of the crossbar is disconnected, and each side is divided into a vertical fixed sun gear, and the middle is connected with a perpendicular non-fixed planetary gear.

Strictly speaking, "half-shaft drive", when walking in a straight line, the speed of the wheels on both sides is the same, and the middle planetary gear does not move, and one wheel drives the car body, and then drives the other wheel to rotate.

When turning, the outside moves and accelerates, resulting in a speed difference, and the middle planetary gear begins to rotate to maintain the entire differential system, and the larger the speed difference, the greater the planetary gear speed.

Once you know the principle, it's not so difficult to make it.

Of course, don't expect the effect to be too good, and it is impossible to make it beautiful, at most it can be used.

That's enough, for those who use a shoebox for the case, it's enough to "be able to use".

Now that you think of it, you have to do it.

Now the gang building has not been completed, and there is no dormitory, so if you want to do it, you can only do it in the system inn.

I spent 20 Wen to find the cheapest inn, went out and cut down a few trees + bamboo, and returned to the city.

First of all, the car body, this is too easy to say, just cut it and fight it.

The wheels are slightly more complicated, and this ink fountain can only be cut off the helmet to the display.

Because he didn't want to waste his time doing another protractor.

In ancient times, there was a "perfect circle" wheel, but Mo Dou didn't want to cut down the kind of big tree that only four or five people could hug, and he didn't have time to grind this into a perfect circle little by little, of course, he could only use a simpler method.

It would be nice to make a regular N-sided shape, draw concentric circles on the paper, cut them into N equal parts, and each piece is directly cut horizontally and vertically into an axisymmetric trapezoid.

Make a ...... 48 sides, so that the upper and lower angles of the trapezoid are 86.25 and 93.75 degrees.

The rectangle is directly cut off a 3.75 degree, and one-eighth of 30 degrees, and the ruler can be satisfied.

After the drawing, take the tape directly and paste it on the screen, and the game will face the copy and start cutting.

After cutting one, compare it with the picture.

It feels like it could be more precise.

I cut four or five in a row and chose the best.

There are 191 left, use this as a mold, just copy the past, simply repeat the work, and read the strip directly.

The rim is ready, and then, the spokes, that is, the middle part, take a random piece of hard log, and round it a little.

Finally, there is the hub, that is, the wooden stick that connects the rim and the spoke, let's use bamboo first, and then cut the log when the stress can not be met.

This is very easy to say, the rim and spokes correspond to the holes, and the bamboo is inserted into both ends.

Simple repetitive work, after half an hour......

"You have comprehended the carpentry recipe - wheels, carpentry experience +1000, current carpentry level 10 106/5000;

Your carpentry level has broken through the advanced level, accumulating +3 knowledge and +3 spirituality"

The system is this stingy ghost.

But since the formula is given, it's good to fight directly.

Convenient.

It's a pity, it's a pity, I spent half a day cutting so many trapezoids before, and now I look at it, I don't know how much time I wasted.
