"Sure enough! Sure enough, it was! ”

Lin Yue held the small gray-white fragment like a crystal in his hand, and his heart was excited!

"I didn't think it was really it!"

Lin Yue looked back at the tall wall, and then at the vast ground, and at the abyss-like existence under his feet.

He finally understood one thing.

That's why the lizardmen are so fanfare, guarding so many beggars with so many people, mining here.

"Saltpeter!"

That's right, these are saltpeter, the saltpeter raw material for gunpowder!

Lin Yue raised his head and looked at the white mountain-like boulder dozens of meters above the ground, and the whole piece was even saltpeter.

The huge pit below also proves that these lizardfolk have been mining for quite some time, perhaps since there were beggars.

It seems that it was a long time ago when I was first blown up by the lizardmen in the main room of the first underground ruin.

Saltpeter......

When mixed with charcoal and sulfur in proportion, it can be made into the most basic black powder.

And this is something that a Stone Age monster like the Lizardmen can't even think of, and no matter how much fire they are creatures, gunpowder is simply their nemesis.

There is no doubt that this is the light of civilization brought to them by the beggars, and these beggars may have existed not long after crossing into this other world.

It wasn't the one he thought would have been after the ancient door of the underground ruins was opened.

The skeletons in those big jars are proof of this.

If that's the case, there's actually a puzzle to solve.

Since the first catastrophe, the decline in the total human population has been extremely slow, if not excessive.

Although there are the remaining people who are getting stronger and stronger, and they are more and more aware of the reasons for how to deal with disasters, in fact, it is not excluded that some people have discovered that they can hide underground and avoid disasters.

Underground these lizardfolk can even give them food, as well as abundant underground water resources for them to drink.

Lin Yue remembered that it seemed that from the third time the group was combined and the scale of 10,000 people, there were not so many survivors who were worried about water and food in the World Channel, and occasionally, that is, those people in the big refuge villages, like Xing Lingfeng and Fei Yue.

It seems that many people in the rest of the world, except for this group in their wasteland, have never worried about water.

Lin Yue once wondered if it was the luck of other groups that were next to the big rivers and lakes, but now it seems that maybe part of the reason is that many humans have gone underground and become beggars, selling the water of the underground river there to the ground in exchange for a large amount of supplies?

It seems that this is not impossible, right?

As for why this saltpeter mine is here, he doesn't want to think about it.

Anything is possible in another world, and if there is a reason, then it is this ore mountain, just like the natural sulfur ore mountain, which is placed there by the "system" to make human survival more difficult and human civilization one step forward.

But now, it has become a breeding ground for human destruction.

Think about it, if a lizardman soldier rushes to a certain refuge village with an explosive...... What will happen?

It only takes a small number to make a refuge village like Liu Kai collapse in an instant!

Lin Yue looked at the hazy rooftops of the shelters below, which were inhabited by beggars who worked for the lizardmen.

Nearly 1,000 beggars are here.

Maybe over time, there will be more of these people.

"Although I would love to bulldoze this place with a Katyusha wave, the downside is ...... It's going to be hard for me to mine in the future. ”

Lin Yue thought in his heart, what to do next.

The Katyusha is indeed very powerful, and it can also turn the two or three thousand lizardmen and beggars gathered here into ashes, but it will also make saltpeter burst into flames!

Saltpeter burns violently at a certain high temperature......

After one round of Katyusha, this saltpeter mine can be turned into a mountain of flames, the kind in the true sense of the word.

It is true that Katyusha can instantly cut a considerable number of lizards and beggars, but the downside is that he doesn't think about these saltpeters.

The lizardmen mined saltpeter ore in order to make black powder and even various explosives, and they also went to the natural sulfur ore mountains to steal it, and the purpose is self-evident.

These lizardmen wanted saltpeter, and he thought exactly the same thing.

He had accumulated enough natural sulfur ore before, and charcoal was found in the Survival Point Mall and the World Trade Noodles Mall.

And the saltpeter, which was necessary to make black powder, stuck him for quite a long time.

At that time, nitrocellulose was considered because of this in the production of bullets, if it wasn't for Xing Lingfeng's side, then he might have stuck on it all the time in the future, so he couldn't use many advanced thermal weapons.

"It seems that there is only another path." Lin Yue's eyes were cold, and he looked at the nearest shelter to him.

If you can't come on a large scale, then break them one by one.

As for the method, it doesn't seem to be too much.

The pit was huge, and there weren't many patrols of the lizardmen, they were all patrolling up and down the mountain paths of the mine, and he picked up his scope and counted them slightly, and there seemed to be 10 teams, each team of about 20 people.

The distance from this side to this side is not too far, but as long as it doesn't make too much noise, they will definitely not come.

Lin Yue looked up at the wall, the death of the two lizardmen didn't seem to have been discovered at all, and he was also relieved.

After looking around, he walked to the vault made of wood.

When he came to the door, he first listened to the movement inside.

Bursts of shrill snoring sounded from within, and there was no light coming from there.

He gently pushed down the wooden door, only to find that it had not been locked from the inside.

Good guys, you're at ease with the lizardmen's guards, aren't you? These reptiles are your own father, aren't they?

The door creaked softly, and Lin Yue stopped, but the snoring of the people inside did not stop.

He dodged in, and through the full-color night vision device, he found that the forty-square-meter room was divided into six compartments, connected by a passageway.

After turning around, I found that there were only six people here.

Six beggars...... At least 6 cubic meters of storage space.

He took out the MP5 and put the infrared sight and muffler on it.

Although at this time, it was the fastest and safest to use a dagger, but Lin Yue didn't want to do that.

The blood of the beggars, too dirty!

Aiming the muzzle of the gun at the door of one of the heads, the trigger was gently pressed, and the snoring was one less.

Second, third, fourth......

Lin Yue's eyes were cold, although he did make some movements, but it didn't matter, if he killed a traitor, the threat of human beings would be one less point.

The six people soon stopped breathing in their sleep, and Lin Yue also collected a total of 9 cubic meters of storage space left by them.

"You don't lose, at least you weren't killed by me with your eyes open."

Lin Yue left this shelter, came outside, and walked quickly to the next shelter.

Beggars......

Death, it's coming!
