In about three days, the rubber tree seeds we planted were fertilized with bone meal, and finally grew into rubber trees. Pen % fun % Pavilion www.biquge.info

This relieved us who were looking forward to the day and night, the stars and the moon.

"Yo Xi, let's start planting trees happily." I crossed my hands on my hips and was dressed in snow-white civilian clothes.

For three days, our lives continued, and occasionally Akai would go out to mine when he was bored, but more time he would choose to wander around the grassland.

Although I have regained a huge amount of power, I have not changed personally, I still have to do what I should do.

The leaves of the three rubber trees fell quickly to the ground under the cutting of the scissors in my hand, leaving a bare trunk in a few moments.

"Four saplings, not bad."

Planting new rubber saplings directly, I collected all the leaf blocks scattered around the ground and threw them into a box dedicated to storing chicken ribs when I got home.

Although cutting leaves with scissors is fast, unlike other tools that can break leaves, the leaves cut by scissors directly turn into building blocks under the action of rules, although you can step on them, but you will always panic in your heart, and there will be an illusion that you are going to fall.

But I can try to make tea, so I have a collecting habit and say that I should not waste it.

"Compared to ordinary leaves, cherry blossom leaves can be used as decorations." After finishing the work on my hands, I touched my chin and said.

"Well・・・・・・ beard has grown again, so it's better to clean it up."

It is undeniable that although it is really longevity and Tianqi, maturity is inevitable during the period from the first teenager who first entered this place to a young adult. But there are no razors in this world, but that doesn't bother our great archmagician.

The magic shield stretched out, and a flame rose from my hand, and I controlled the flame with precision to burn the beard growing on my chin very clean.

"Whew~ perfect, so I'm a few years younger, just kidding." After a little self-deprecation, I walked towards my home.

Of course, the raw rubber from the three newly grown rubber trees was also sucked out by me with a wooden faucet.

Now it's time to go back and make the real basic product of industry, that is, wires.

Industrial technology wires are divided into the following types: popular, local tyrants・・・・・・

Ahem.

To be precise, it should not be called a wire, but the correct scientific name should be called "cable".

Cables are divided into insulated cables and uninsulated cables.

As the name suggests, an insulated cable is one that is wrapped in rubber so that you won't get electrocuted when you grab the cable with your hands. As for uninsulated cables, if you really want to take uninsulated cables in a pile of electrical appliances, be sure to prepare insulated tools.

When I got home, I took out three copper ingots from the box and put them in a line on the workbench, and the next moment, the six [uninsulated copper cables] were synthesized.

Copper cables are the easiest, cheapest and most important cables to make, as all machines need this basic item in the future.

"And then there's the burning of raw gum." As I spoke, I put the original gum in the iron furnace, and since I usually accumulated a lot, we have already counted thousands of coals and charcoal.

Actually, Akai and I were uncomfortable looking at the empty stove, so we threw something into it and burned it when we had nothing to do, but it was basically a lot of logs, ore, and cobblestone.

Although you can get it by trading with the villagers, who made it expensive for those profiteers?

After waiting for about fifteen minutes for the uninsulated copper cables, I removed the fired rubber from the iron furnace.

The rubber in the shape of a black ball always makes me want to play marbles, is this nostalgic for my childhood?

Sighing, I flipped through my old memories and put the uninsulated copper cable and rubber into the workbench.

[Copper cable], this is what I want, the most basic product of industrial science and technology.

"En~ Where did the introduction come from? Yes! Found it, I'll take a look at ・・・・・・"

Flipping through the industrial brochure in my hand, I looked at the various values of copper cables.

The industrial guide that manifests the world consciousness is very detailed, and both the synthesis method and the specific values are clearly recorded in it, saving me a lot of time to explore.

According to the book, the unit of electricity in this world is [EU] (batbox).

I looked at the copper cable in my hand, "Is the upper limit of this thing 32eu electricity, I see, if it exceeds it, it will explode・・・・・・ it's really dangerous." ”

"Yo, I'm back~"

As I carefully examined the copper cable in my hand, Akai's voice came from the door.

"You're back just in time." I said with a smile, and then tossed the copper cable in my hand to Akai.

"What is this?"

Putting down the things in his hand, Akai caught the copper cable, raised it and looked at it, "Wires?" ”

"yes, plumber's wire, what do you think, boy."

"It's really a primitive wire, is it copper, how do I feel that the copper ingots are cut into one by one and used directly as wire conductors."

I handed the uninsulated copper cable to Akai.

"What is this, spicy strips?" Although he knew what it was, Akai continued to spit out.

"You can take a bite and try it." I said helplessly, "Maybe you can make spicy strips when you have chili peppers in the future, but now ・・・・・・."

"But now that we have wires and cables, we can almost make batteries." Akai suggested.

I nodded, and then I started working on the battery.

Don't look at the resources in our chests, there are also a lot of various ores, if you really want to climb the industrial technology tree, those resources are not enough. This is the result of three days of boredom waiting for the rubber tree to ripen and paper to do the calculations.

Not only is there a lot of copper and iron, but tin ore is more in demand than iron and redstone because of batteries.

The materials required for a rechargeable battery are a copper cable, two redstones, and four tin ingots.

At first glance, it doesn't seem like much, but considering all the equipment involved in power storage and power generation that followed, a battery that required four tin ingots to make was too resource-intensive.

"Then I'll go put things first, the harvest of hunting today is good, and this kind of thing is not suitable for me at all."

Akai shrugged his shoulders and walked upstairs, and I laughed and continued my research.

――――――――――――――――I'm a dividing line――――――――――――――――

After several hours of research, I was able to identify the various properties of the battery.

【Eco-friendly multi-use super bunker universal rechargeable battery】! That's the name I gave to this unremarkable-looking battery after researching it.

Can be reused without any contamination.

If the energy of a piece of coal is 3,000 eu, then a rechargeable battery can carry 10,000 eu of electrical energy.

There is a blank groove of ten grids on the surface of the battery, and there will be a red bar that fluctuates up and down with the amount of electricity loaded inside, and green if it is full, which is convenient and intuitive.

Of course, rechargeable batteries are also an essential component of many machines.
