It is a natural cave that was originally used by the tribal alliance to store animal skins.

But because the preparation of gunpowder requires a special place, and it cannot be too close to the residence.

Therefore, Lin Luo directly requisitioned this place and asked people to remove all the animal skins and convert them into a gunpowder preparation room.

When it was used as a storage cave, the cave was artificially expanded and looked very spacious.

Since there can be no open flame, several fluorescent stones are specially inlaid on the wall of the cave, so that the cave does not look dim at all.

"Knock! knock......"

As soon as the four of them stepped into the cave, they heard the sound of stones hitting inside the cave.

I saw that in front of a stone table in the cave, a figure was pounding sulfur ore into powder with a stone mortar.

Hearing the movement behind him, the figure turned his head to look at it, and immediately bowed to the two chiefs of Bamboo and Fox and said, "Chief!"

This craftsman is not a member of the Bamboo Clan, but a member of the Fox Clan.

Because the preparation of gunpowder is very important, it must be done by careful and careful people.

Therefore, after Lin Luo deleted all the craftsmen in the tribal alliance, he finally chose the craftsman of the fox clan.

At this moment, the craftsman was dressed in sackcloth and wore a mask covering his mouth and nose.

Whether it is sulfur powder or saltpeter powder, it will cause harm to the human body after smoking.

Therefore, Lin Luo had a specific person before, using linen cloth mixed with charcoal powder in the middle to make a batch of simple masks.

"Hmm. ”

Hearing this, Chief Bamboo nodded and said to the craftsman, "Keep doing it!"

"Yes. ”

The craftsman nodded in response.

Lin Luo, on the other hand, walked to another stone table not far away, took four simple linen masks, and distributed them to the three chiefs.

While putting on his own mask, he said, "Chief, you guys put on all your masks!"

Looking at the sackcloth masks distributed by Lin Luo, the three chiefs didn't know what it was for.

But he still followed Lin Luo's example and put the mask on his face.

After that, Lin Luo handed the clay pot containing saltpeter to the craftsman and said, "Mash all these saltpeters into powder." ”

"Good. ”

Hearing this, the craftsman nodded in reply, and immediately did so.

Lin Luo picked up the other two clay pots on the table and walked to the stone table where the sackcloth mask was placed.

It can be seen that on that stone table, in addition to the burlap mask, a simple weighing tool is also placed.

This is also what Lin Luo has made in the past few days.

Inside the two pots, there was black charcoal powder and yellowish sulfur powder.

Lin Luo quickly picked up a small bamboo tube, scooped the two powders from the clay pot and began to weigh them.

On the side, after Lin Luo's previous safety science, the three chiefs all held their breath and stood aside quietly watching Lin Luo's operation.

Soon, when Lin Luo finished weighing and poured all the two powders into a pottery bowl, the craftsman also pounded all the saltpeter into powder.

Lin Luo took the saltpeter powder and continued to weigh it.

The ratio of gunpowder has been changing since ancient times.

To be honest, Lin Luo didn't have much knowledge in this area, and the ratio he knew was 60% saltpeter, 20% sulfur, and 20% charcoal.

He wasn't sure if this ratio was the most scientific, so he could only prepare one according to this ratio first and see how powerful the explosion was.

Soon, after the saltpeter was also weighed, Lin Luo poured it into the pottery bowl and stirred it with a bamboo stick.

"Alright!"

It wasn't until all the three powders were stirred evenly that Lin Luo stopped.

To be honest, although the gunpowder has been prepared now, it is not the best in Lin Luo's mind.

If you want the gunpowder to get the most out of it, you should continue to add some honey water, and then press the gunpowder to dry before using it.

In that way, the density of gunpowder is greater, and the effect of the explosion will be better.

As for why honey water is added, it is because the sugar in honey will decompose into water and charcoal when heated.

When detonated, the charcoal acts as a fuel for combustion, making the explosion more violent.

It's just that if you do, it will take at least a day to dry.

But at this moment, Lin Luo couldn't wait to see the power of the gunpowder explosion.

Therefore, this step was temporarily removed.

"This is gunpowder?"

Hearing Lin Luo's words, looking at the black powder prepared in the pottery bowl, the bamboo chief said out loud.

"These powders are weapons?"

On the side, the fox chief had a skeptical expression on his face.

"Gunpowder has to be made into a bomb to be considered a real weapon. ”

Hearing this, Lin Luo said as he walked to the other stone table next to him with a pottery bowl.

It can be seen that on this stone table, there are more than a dozen bronze balls that are slightly larger than fists.

These bronze balls are hollow inside and have a small hole at the top.

To be honest, as for what kind of thermal weapon to make with gunpowder, Lin Luoke has thought carefully.

Now, the tribal alliance has long had bronze, not to mention muskets, even cannons can be cast in bronze.

However, Lin Luo did not choose to make muskets and cannons in the end.

After all, this is not Earth, it is a different world full of fantasy.

It is simply impossible to dominate here with more primitive firearms.

Whether it's a musket or a cannon, it takes a lot of time to reload.

During this time, I don't know how many times I have killed enemies or beasts.

Moreover, unless he suddenly creates a thermal weapon comparable to modernization.

Otherwise, whether it is a bullet from a musket or a shell from an artillery, as long as the strength reaches the bloodline warrior, it will be able to dodge the past.

Not to mention the beasts that are more agile and have tougher fur.

Therefore, in this primitive world, taking a primitive firearm to hunt fierce beasts or attack other tribes is simply an act of looking for death.

Therefore, Lin Luo finally chose to use bronze to make a bomb.

In contrast, the bomb is a little more flexible.

As long as you ignite the fuse, you can throw it far away like a stone, making it a great long-range attack weapon.

It doesn't take a lot of time to fill the gunpowder, and even a dozen shots can be thrown in an instant to cover a certain area.

Lin Luo held the bronze ball in one hand and the pottery bowl in the other, and quickly poured all the gunpowder in the pottery bowl into the bronze ball from the small hole at the top.

After that, take out a long thin thread from the clay pot next to it and insert it into the hole.

This thin thread is made of a kind of velvet and burns quickly when ignited, making it ideal for use as a fuse for bombs.

After the lead was ready, Lin Luo took out the cement specially used for sealing from another clay pot and sealed the small hole at the top of the bronze ball.

And so far, the first Bronze Bomb has been made!
