Although Su Heng is illiterate in the chemistry area.

But even a fool knows that crystalline saltpeter is much more practical than saltpeter full of impurities!

"Too little, too little, too little!"

Su Heng originally planned to mine two ore veins, which could supply gunpowder for a considerable period of time.

"That's it, I don't know how much gunpowder Dr. Li can make."

"Six ammo is definitely enough."

"Ow~"

"Why?" Su Heng looked at Lolo at his feet.

Its expression was serious, as if it was warning Su Heng that there was danger in the vicinity.

Su Heng quickly exited the mine and took Lolo to a hidden place to hide.

He took out the thermal imaging telescope that the system had previously awarded, and sure enough, at a position of more than 200 meters, he saw two living bodies moving.

Through the thermal imaging mode, Su Heng easily found them.

"It seems like... a person?"

Su Heng turned off the thermal imaging mode and clearly saw that it was indeed two people.

Two people, one tall and one short, one fat and one thin, were timidly touching the ore vein.

It didn't take long for the two to move to a position where Su Heng could see without using a telescope, and they could hear their movements in their ears.

"Boom~"

"Boom~"

"Eh? I clearly heard something going on here, like something exploded." The tall, chubby man with dark skin and a beard asked suspiciously.

A short, thin man with fair skin said impatiently, "Where is it, why didn't I hear it?"

"You must have heard it wrong! Let's go back quickly."

"Impossible, I heard several explosions, don't pretend you didn't hear it." The fat man glanced at the short and thin man, and said in an angry voice, "Wait, it should be here! Look at the high temperature smoke on the mountain wall. Black marks!"

The fat man's eyes were sharp, and with just a few steps, he reached the location of the mine where Su Heng had just blasted and hadn't had time to mine.

"What is this? Why is it so stinky?"

The fat man's expression changed suddenly, he covered his mouth and nose subconsciously, and grabbed a bit of salt in the mine.

"This is nitrate!"

"Look to see if there is any saltpeter in it!"

The short, thin man's eyes gleamed with ecstasy.

"This glass slag-like thing is saltpeter? What's the use?"

"You don't understand, this is the raw material for making gunpowder!"

"Everyone is still in the age of cold weapons. If this thing is put on the exchange, someone will definitely be rushing for it!"

"Hurry up, let's get these resources away, and the exchanged materials will be enough for us to live for half a month!"

A look of displeasure flashed across the fat man's face: "I said bro, if you don't want to get the airdrop, just say it, don't talk about saltpeter."

The short man frowned: "Do you think I'm lying to you? I didn't lie to you! If you don't believe me, you can look at the attributes of the entry above."

The fat man snorted coldly: "You know I can't read, but you still let me see the attributes of the entry? Bully me for not reading, right?"

"Our father asks you to study, but not me. You sweat every time you do any work. If you don't want to go, you can leave. The brothers and I will just split up."

"My safe house hasn't been set up yet, your safe house will be yours."

The short man was also very displeased: "I said Erping, what do you mean by that? Do you think your brother is holding you back?"

"At that time, my dad said that it was for two people to read, but you didn't read it yourself. Now you blame others?"

"I've already said it, all the airdrops have been put down, and they've been taken away by others long ago."

"Let's go there now, we'll definitely miss out!"

The fat man retorted: "How do you know if you don't try?"

"Didn't we come all the way here just to give it a try? I really don't want to go back."

"I'm going to you, I'm not going." The short man fell in love with this small mine, and was directly attracted by it and couldn't walk.

The two quarreled over this issue.

Su Heng watched from behind, and most likely understood the situation of these two people.

The two were brothers and were dropped together. Because the eldest brother procrastinated, they moved slowly, and the distance between them was relatively far, so they have not yet reached the airdrop position.

Judging the characters of the two from their words: a short man with a steady older brother and a fat man with an aggressive younger brother.

The quarrel between the two continues, from the issue of airdrops, to family ethics, and then to family separation.

Su Heng silently wound the crossbow, ready to fire arrows at any time.

"Okay, you're not going, right, then this mine is mine too."

"If I hadn't pulled you to get the airdrop yesterday, would you have discovered this mine?"

The eldest brother took a step back: "Half one person is enough, right?"

"no!"

"Why not? Shouldn't the family be separated by half?"

"How do you use mine for what you eat these days?"

The two quarreled fiercely.

Su Heng made up his mind not to stay alive.

Peaceful coexistence is absolutely impossible. Brothers and sisters can quarrel over the interests of a mine, not to mention that Su Heng is an outsider?

If he didn't kill him, the other party would definitely take this mine, and Su Heng had to toss for nothing all afternoon.

If Su Heng was in the position of the two brothers, he would definitely be treated in the same way, even more cruelly.

While Su Heng was thinking, the quarrel between the two stopped.

They seemed to realize a problem at the same time.

The explosion just now... how did it come from?

"Will this thing explode on its own?"

"No... The melting point of saltpeter is above 330°, which is very stable."

"Where did the explosion just now come from?"

"Not good! Someone!"

Both of them realized the danger here at the same time.

But before they could run away, a cold arrow was shot from 40 meters behind.

swoosh~

"Ah ah ah ah ah!"

Su Heng's precise, tall and strong-looking second brother~lightnovelpub.net~ is very aggressive.

The crossbow arrow penetrated his chest, killing him on the spot!

When the little elder brother saw that his own younger brother was shot, he dropped the second younger brother's body on the spot and ran away.

Su Heng would not let him run, the second and third crossbow arrows were already on their way.

swoosh~

swoosh~

"Ow~"

Lolo asked Su Heng to come forward to fight.

With Su Heng's permission, he jumped out of the bushes and ran towards the short man.

The short man looked back and found that Lolo was rushing towards him.

"Ahhh! There are tigers!!!"

"Help!!"

"I don't believe it can't be shot!"

swoosh~

Su Heng's fourth crossbow arrow hit the short man's thigh, but it didn't penetrate.

The short man was knocked to the ground, tried his best to get up, dragged the thigh that was hit by the arrow, and continued to run for his life limping.

His speed was much slower, and at this time, Luo Luo had already caught up, kicked his hind legs sharply, and the whole tiger body leaped up, knocking the short man straight down.

Luo Luoya's mouth has grown very sharp, and she firmly bites the short man's neck.

"It seems that there is no need for another shot."

Su Heng observed with a thermal imaging telescope, that the short man had been bitten by Luo Luo to the aorta at his neck, and he died in a few seconds.

Immediately afterwards, Su Heng observed the situation of the nearby 2km.

After confirming that it was safe and no one else would appear, he slowly appeared.

In less than 3 minutes, the two brothers were killed by Su Heng's hands!

The whole process was neat and tidy, not at all sloppy!

"In the last days, to be compassionate to others is to be cruel to oneself."
