So generally speaking, when making a tool, its parts are best assembled with the same materials, after all, this is not like a game, as long as a tool is done in the game, then the durability becomes a fixed whole, even if it is a wooden handle of the Mayu Ling pickaxe, its durability is more than a thousand. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

Here, the durability of each component is different and calculated separately, and when the durability of one of them runs out, the entire tool cannot be used and must be repaired again.

In addition, the advantage of using the same material to assemble parts to make a tool is that when any part of the tool is damaged, the same material is needed to repair it, such as an iron pickaxe made entirely of iron parts, whether it is a handle, a pickaxe, or a binding knot that is broken, it can be repaired with an iron ingot.

However, if it is an iron handle, a copper binding knot, or an acid-resistant aluminum pickaxe, you will need to keep these three different metal ingots on your body in order to repair them, not to mention the trouble, and it will take up space in your backpack.

The same goes for the acid-resistant aluminium tools they now have in their hands.

The reason for mentioning the production of tools and parts here is that if you want to make more advanced metal parts, you can no longer use ordinary wooden molds, and you must use a craftsman's soul smelting furnace to pour more advanced metal.

In the same way, they must first make metal molds from aluminum brass before metal pouring, and only aluminum brass molds can withstand the pouring of hot metal liquid, otherwise everything else will melt under the metal liquid.

The things necessary to pour aluminum brass metal molds are stone parts.

There are only a few parts that can be made from wooden molds, such as flint, wood, stone, and hellstone, which do not need to be poured through a smelting furnace, and among them, only stone is a material that cannot be used to make tools; Parts of other materials can be combined to form tools.

Only stone, only stone parts such as stone handles, stone binding knots, etc., cannot be combined, it has only one purpose - for pouring aluminum brass molds.

This aluminum brass mold is not infinite durability, it will be damaged after a few uses, so they also need to be replaced from time to time, this back and forth with stone parts is naturally more, and the handle is the part they use the most, so from the time they made this craftsman soul smelting furnace to the present, they have made the stone handle the most.

Of course, the stone parts are not only used for this, but they also have many other uses, but they are still waiting to be discovered by the two of them - for example, now, don't they know that they can make stone ladders with stone handles?

Like the stick, this stone handle can be placed directly in the workbench, and two rough stones can be combined into four stone handles, of course, it can also be made using a handle mold, and the yield is the same.

The stone handle that is synthesized from this, and the way the ladder is made, can naturally make a stone ladder - the same is true for other metal ladders, except that the stone handle synthesized directly in the synthesis table is replaced by a metal handle poured out of the craftsman's soul smelting furnace and mold, and then synthesized with the metal handle.

However, perhaps because metal is more precious and tough than stone and wood, it costs more to cast a metal handle than a stone handle, and the same number of seven metal handles can make six rows of metal ladders, which is twice as much as a stone ladder and a wooden ladder.

Of course, even so, they would definitely not choose to make ladders out of metal, just kidding, metal is so difficult to dig, and its use is more extensive than stone, who would use metal to make this ladder that is useless except for the current emergency?

And stones are everywhere, and it is the most cost-effective way to make a stone ladder to do it.

After learning this, they did not immediately start to make the stone ladder, but reached out and gently touched the icon of the stone handle on the light curtain in front of them - they wanted to see what else this stone handle could do?

The picture changed, but the pattern that appeared in front of them at the next moment was a surprise to their eyes, and at the same time, they were faintly disappointed.

The use of the stone handle is not as many as they imagined, they thought that the stone handle as a product of replacing the wooden stick, not to mention its use and the wooden stick for nearly a hundred pages, there must be at least half of it, right?

However, it seems that the stone handle can't really replace the wooden stick, after all, it is only a product of the Craftsman's Soul mod, and can only be used on the things of the Craftsman's Soul.

In addition to being used to craft ladders, stone handles can also be used to craft torches......

That's right! Torch! It's a torch! Stone Torch!! What a scientific cube world!

It's good to say that wooden torches can burn, how do you burn this stone torch, hey! Is it enough to poke the coal on the handle? The wooden handle of the original torch is simply used in the hand! It's just the little bit of coal at the top that shines!

They also thought that the stick itself was also fuel, and that the coal of the meow could only last eight items when it was placed in the furnace, and that it could burn permanently like a perpetual motion machine when placed on a torch......

There used to be the victory of scientific mahjong on earth, and now here is the victory of scientific torches......

And according to the information on the light curtain, this stone torch will only glow, will not heat, and will not release the characteristics of flames, just like a firefly with much higher light intensity, that is to say, this stone torch is specially prepared for the underground tunnel in the craftsman soul module, and will not ignite the gas and cause gas explosions and other things, well, science, science......

So what's the use of the lanterns you've given them with the Book of Guides!

Xia Aya looked at the lantern in her backpack that was so extravagant that it was made of gold, and almost threw it out excitedly, one can make four torches with a stone handle and a coal, and the other needs torches and gold, glass and other items to make a lantern......

The effect of the two is not much different, at most the latter looks beautiful and high-end......

Meow's cost-effective gap is too big, right?! Who would use that much gold to make something that looks good, but serves the same purpose as a stone torch in survival mode! And they're in extreme mode, okay?

In fact, the problem that the torch will ignite the gas and cause the gas explosion has been solved, and they should be happy, why are the two of them looking at each other now, feeling inexplicably not a taste?

Both of them looked at their backpacks, it must be because of the broken lantern!
