High-end goods!

After Li Yan finished interpreting the refining furnace with alchemy, he had to smack his lips and admire a few times.

Although the refining furnace itself is crude and rudimentary.

But because of the addition of "black technology" such as alchemy, it has become a fully automated material extractor, and it only needs to add combustibles, and then choose the refining formula with your mind.

Compared with the machines on the earth that are either cumbersome to operate or require huge electronic instruments to control, the refining furnace in front of me is simply too "high-end".

"Try it first!"

Li Yan grinned, immediately opened the lid, and threw the remaining iron ore, mixed with the ashes and slag of plants and trees burned by the fire, into the refining furnace, and then piled up wood and wild grass at the bottom, and finally lit it with fire.

When he put his left hand on the refining furnace, the alchemy array at the bottom of the furnace immediately connected with his consciousness.

So, he chose the refining formula of iron ore.

Immediately after, in my mind, a refining panel appeared, with the refining progress and refining efficiency on the top, and the duration of the burning substance below.

He counted for a moment.

To completely refine one cubic meter of iron ore into iron blocks, at least two or three cubic meters of wood are needed.

In other words, you need to keep adding firewood to it in the middle.

As for the refining efficiency and progress, it is about four pieces of iron ore, and one piece of iron can be smelted, and the time consumed is about half an hour.

Fortunately, the iron blocks of the refining furnace are all refined at the same time, and when a furnace is filled, at least two dozen iron ingots can be smelted.

More than half an hour later.

Li Yan opened the lid of the furnace and used wooden tongs to take out the iron pieces one by one and put them in a wooden box filled with water to cool.

Against the backdrop of fire and moonlight, the iron ingots shimmered with a shiny metallic sheen.

It is rectangular in shape, one circle smaller than a chalkboard eraser.

Roughly estimated, it weighs about a pound.

He took out the iron ingots in the alchemy soul stone, and compared to the two, they were almost identical.

It seems that the native life of the Origin World also uses such a refining furnace.

Li Yan thought for a moment, then replaced it with sulfur ore and plant ash, and filled it with firewood.

Compared with refined iron ore, sulfur ore refining is much easier.

Not only is it more economical to burn the material, but it also takes less time.

It took less than twenty minutes.

He got a small pile of yellow, lumpy solids, which was sulfur!

"Beautiful! When the soil nitrate is successfully stewed, the black powder will not be a problem! ”

Li Yan picked up a piece of sulfur, lifted it, turned it repeatedly, looked at it twice, and immediately laughed.

Then, he packed all the sulfur into the alchemy soul stone.

This thing is volatile, and if you put it in a wooden box casually, it won't take long for the sulfide to become less, and the effect will not be good.

Rested for the night.

Day 4.

As soon as Li Yan got up, he hurriedly ran to the catalytic box next to the wooden house, and a stinking smell immediately came to his nose.

"Nima, who pulled this, it stinks!"

He scolded.

When many dinosaur brothers heard this, they all shook their heads, indicating that they didn't pull it themselves.

He didn't bother to ask, but he secretly decided in his heart that if he really wanted to lay a catalytic box on a large area, he would have to build a special house.

Otherwise, if you let the mixture of and grass in the yard, you will be smoked to death if you don't get eaten by the dinosaurs.

Subsequently.

He took a peek at the stench and glanced at the surface of the catalytic box.

I saw that on the yellow-green, viscous swill-like mixture, there was a faint layer of white dots floating.

These small white spots are not moldy fimbri, but salt-like crystals.

Li Yan's face was excited, and he just wanted to open his mouth to laugh.

As soon as he remembered what this thing was, he hurriedly took a few steps back, and then grinned, "It's done!" ”

That's right.

Those white crystals are a mixture of potassium nitrate, as long as they are collected, dissolved in water, filtered, and purified, potassium nitride will be obtained, that is, saltpeter for making gunpowder and explosives!

But.

In the blueprint of black powder unlocked by the system, it is indicated that only earth nitrate is required.

The so-called earth nitrate is the mixture of potassium nitrate in front of you.

In other words, Li Yan doesn't have to bother purifying it, as long as he wants to pick out these white crystals, he can directly use them to synthesize!

"Great!"

In addition to being excited, Li Yan immediately ordered the fat rats with limbs to dig a few holes more than 10 meters away from the campsite, and then ordered: "In the future, everyone is not allowed to anywhere near the jungle, if you want to, you can only do it in the pothole, understand?" ”

"Moreover, everyone has eaten more recently, and strive for Dora, who pulls more, there will be a reward!"

In the face of such an embarrassing order, many dinosaur brothers could only head a little.

At this point, the first public toilet in the prehistoric world was born!

This is also something that can't be helped, Li Yan is also very helpless, who let the current production of earth nitrate, as well as the synthesis of paralyzing poison, need animal dung.

Now, has become a "fragrant bait", and it looks like it's almost insufficient!

One mentions paralyzing poisons.

At the time of breakfast.

The pangolin began to report on the collection yesterday afternoon, a total of three moon flowers, two dragon grasses, and three new ones: scorpiontails!

Li Yan brought the scorpion grass.

Ooh!

It's really vivid, this weed is about thirty centimeters long, with a main stem in the middle and four or five slender auxiliary leaves next to it.

Unlike the usual upright wild grass, the main stem of the scorpion is curved, like the tail of a scorpion.

At the very top, there is a red, scorpion-like nodule.

Li Yan tried to interpret it with alchemy, and indeed found two kinds of poisonous substances common to the earth, as well as some unknown ingredients, which were estimated to be specially bred by the origin world.

Just today I'm going out looking for mount domestication.

He plans to use these scorpion tails to synthesize paralyzing poison.

Because every time I go out hunting, when I come back, I will carry a large amount of raw meat and pile it up in the material warehouse.

In the long run, there will be rotting raw meat.

Therefore, the carrion and animal feces needed for paralysis poison are all readily available.

Li Yan, find a large fern leaf, put these things on it, and raise his hand to close it.

The material disappeared immediately, and in its place was a large puddle of green viscous liquid, about one or two hundred milliliters.

He smelled it slightly from a distance, but there was no smell, and there was no sign of dizziness afterwards, indicating that the venom was not volatile.

Next.

Li Yan coated all the stone arrows and stone spears synthesized, including his one-handed sword, with this paralyzing venom, anyway, the system calibrated that the stability of the venom was extremely strong, and if it was applied in advance, it would not deteriorate.

When everything is ready.

He began to assemble a team of dinosaurs and set out towards the jungle in the northwest in search of a new mount!
