"I should have thought of it!"

"The richest resource of Linghu lake is not only the fish in the lake, but the rich nitrogen, phosphorus and potassium on the shoreline of the lake! We're almost there, right ahead!"

Taking mosquitoes to the lake, the wind said excitedly all the way.

They stopped at a shoal by the lake.

With lush vegetation and easy to hide, it is an excellent water intake for both humans and animals.

As soon as the strong wind stretched out his hand and was ready to point, the mosquito stepped forward first, walked to a relatively flat rock and squatted down.

I saw him stretch out his index finger, gently wipe it on the stone wall, then smell it close and try to lick it.

The strong wind didn't care about the hot eyes and asked quickly.

"How's it going?"

Spitting on the ground, the mosquito's face was half happy and half sad.

"Bah, why are there any fresh..."

Strong wind: "

Although I accidentally tasted fresh bird droppings, one thing is certain that there are a lot of bird droppings here.

The main component of this ore is Mg (NH4) [PO4] · 6H2O, with orthorhombic structure. It is not difficult to see how widely it can be used by looking at its chemical composition.

Moreover, when a certain amount of guano stone is formed, the ammonia in it will be gradually oxidized into nitric acid under the action of nitrifying bacteria, and finally accumulate under the soil in the form of potassium nitrate, sodium nitrate, calcium nitrate and magnesium nitrate to form the so-called nitrate soil.

This kind of nitrate soil, as an "associated ore", only needs to be boiled by simple methods, such as mixing with plant ash without filtering out potassium alkali water, and separating out calcium and magnesium ions, so as to prepare nitrate containing a small amount of impurities!

In short, once you find bird droppings, you basically master saltpeter.

And having saltpeter is basically equal to having gunpowder!

In fact, it is not just bird droppings. A large number of heterogeneous excreta are distributed on the Bank of Linghu lake. These excreta are gradually weathered and hardened with the passage of time, and finally formed dung ore.

As for why there are so many dung stones by the lake, it's actually very easy to understand.

In the early years of the waste earth era, the planet experienced a severe cold period of nearly half a century.

During that period, Linghu Wetland Park, as the area with the most abundant water resources, once had a large number of wild animals and livestock fleeing the pasture.

These feces should have been left at that time.

It was not until the end of the severe cold period and the uninhabited urban area formed a more lush ecosystem that it was gradually deserted.

"With these nitrates, it's not a big problem to get the black powder out!" he stood up from the ground, and the mosquito looked excitedly at the wind. "Give me a hand and let's get more back."

Asked the wind in doubt.

"There is nitrate soil and charcoal, but I remember there is sulfur in the formula of black gunpowder. Where are you going to find sulfur?"

If he remembered correctly, sulfur usually appears near craters or hot springs.

However, this area obviously doesn't look like these two things.

The mosquito was stunned.

Obviously, he hasn't had time to consider the problem.

"Er, sulfate is OK without sulfur, but the process is a little troublesome... It should be easy to find?"

The strong wind looked around and shrugged helplessly.

"Anyway, let's look first."

……

Unfortunately, there was no sulfur in forest, and there was no suspected sulfur by lake.

Think about it.

How can this thing appear in the wetland park?

Fortunately, when they were about to give up, they found some gypsum mines by a small river extending out of Linghu lake.

The ingredient of this thing is calcium sulfate. Burning with carbon at high temperature can produce calcium sulfide and carbon dioxide. It is the sulfate mineral they are looking for!

"Why did I forget this?" the mosquito slapped him on the back of his head in frustration. "I saw Lao Bai burn cement two days ago. It seems that they mixed this gypsum powder into it! Isn't this fucking calcium sulfate?"

Said the wind with a wry smile.

"This is the so-called black under the lamp."

"In a word, the result is good," he picked up some gypsum ore and put it into the plastic bucket. The mosquito washed his hands, stood up and looked at the wind and said, "let's go. The materials are done. Let's go back."

The gale nodded and followed him.

The two returned to the survivor's settlement together. They were about to go to the cabin, but they found that there was a commotion in front of the door of the settlement.

I saw the players working on the construction site, I don't know when they had come down from the scaffold, and they all carried guys in their hands and surrounded a cow with two heads.

Next to the two headed cow stood a strange man.

He wore a leather jacket, a flattering smile, made strange gestures, and muttered something incomprehensible.

The mosquito looked curious and stopped.

"Who is that person? New NPC?"

I haven't heard that it will be updated today.

"I don't know. I'll ask..."

Fengfeng is an activist. He puts down his plastic bucket and walks to the fried egg brother standing in front of the bacon rack to watch the excitement. He pulls him and asks curiously.

"What happened there? Who is that man?"

The fried egg brother held his arms and shook his head.

"I don't know the details. According to others, it seems that our people met this guy on the way back from the construction site, and then this guy didn't say anything. He followed us all the way here."

The wind approached and heard the players talking.

"Why did the cow have two heads?"

"Domesticated alien?"

"This man is with us! I bet he's not a good thing. Maybe it's the work of the predator!"

"Not necessarily. What if it's NPC?"

"The truth doesn't make sense. If it were NPC, wouldn't it be impossible to communicate?"

"Can it be that the condition is not triggered?"

"Why don't we lock him up first and wait until the manager comes back?"

Sun Shiqi, who was surrounded by the crowd, felt great pressure.

Although a revolver was hidden under his leather jacket and the insurance had been turned on, even if he emptied the magazine, there were only six bullets.

The residents of the nearby shelters would not give him the chance to shoot six times in a row.

One hammer a man, he'll have to lie on the ground.

"I repeat, I have no malice. I'm a businessman. Do you understand? Damn it, even if it was worse 200 years ago, I wouldn't even have a business career? Or did you sleep too long and forget?"

"Well, calm down. To put it another way, I want to use these things on the cow's back to exchange with you something you don't lack and I just need... Anything can be! Of course, if you don't want to change, it doesn't matter. I'll leave now and promise not to disturb you again!"

Seeing that there was no communication at all, sun Shiqi had a retreat.

However, the residents of these shelters did not mean to move away at all. Instead, they got closer and closer, and even took out ropes.

Sun Shiqi was in despair.

Just as he was thinking about whether to fight hard, the blue coats surrounding him suddenly made way.

A man, carrying the body of a mutant reindeer on his shoulder, came this way.

The mutant reindeer weighed at least more than 100 kilograms and was about to catch up with a horse. However, the man walked as usual carrying prey that could cover himself.

Although he was wearing a harmless blue coat, sun Shiqi still smelled an extremely dangerous smell from him.

This guy

Definitely not an ordinary shelter resident!

The man threw his prey heavily on the ground and said a few words to his companions. Then these people dispersed obediently.

Looking at the man walking towards him, sun Shiqi was nervous and nervous.

For a moment, an idea flashed through his mind. If you can hold the person in front of you, you may be able to leave here smoothly.

However, his intuition told him that if he did, he would die at the moment of doing it

"Who are you?" Chu Guang looked at him and asked.

Sun Shiqi was stunned when he heard the man talking to him, and a surprised expression appeared on his face.

"Can you speak? No, I don't mean that. I mean you can speak the language here?"

The language here refers to the conjunction of nature and man.

Before the war, this area belonged to the territory of the people's Federation, and the language used was naturally unified. Normally, the residents of the shelter also use human couplets, but I don't know why these people are a little different.

Chu Guang frowned slightly and looked at him and continued.

"Now I'm asking you."

"Answer me, who are you?"

Hearing the bad tone, sun Shiqi quickly explained.

"My name is sun Shiqi. I'm from Honghe town next door. I'm a businessman!"

Honghe town?

Hearing this strange place name, Chu Guang raised his eyebrows gently.

He only knows that this is Qingquan City, a river valley province in the hinterland of renlian. As for other cities in the valley province, he is not very clear.

"What are you doing in Qingquan?"

Sun Shiqi said carefully.

"I'm a businessman... Of course I'm here to do business."

Chu Guang's expression didn't move.

"Merchant? Then why did I hear my companions say that you followed them?"

"Misunderstanding, this is definitely a misunderstanding!"

Sun Shiqi waved his hands and explained in tears and laughter.

"I was going to go to Boulder City. I happened to see them wearing blue coats on the road. I thought there were shelters nearby, so I wanted to change something with you... I'm just a businessman. I really don't mean to offend!"

He didn't expect these people to be so sensitive.

If it was an ordinary place where survivors lived, he definitely didn't dare to lean over alone, but if it was a shelter, it would be different.

These little cute people in blue coats are famous silly white sweets on the waste land. They are easy to bully and cheat.

They are usually the elites of the pre war society or the descendants of the elites. They often boast of the descendants of civilization, arrogant and arrogant.

At that time, he thought that he would follow the past. He would not lose anything if he was chased away as a beggar.

I didn't expect that after these people brought him in, they surrounded him without saying a word, didn't listen to him, and didn't intend to go.

There's no martial virtue!

Chu Guang didn't relax his expression because of the guy's explanation. Chu Guang still looked at him expressionless and continued.

"No matter whether you mean to offend us or not, you have indeed done something to offend us. I believe tracking is not a friendly behavior in any corner of this waste land, are you right?"

Sun Shiqi was sweating and nodded hard.

"... you're right."

"Well, it seems that you have realized your mistake," Chu Guang nodded, "but don't worry. We are reasonable people. Just now I have convinced my companions that you are willing to apologize for your offensive behavior."

Sun Shiqi nodded quickly.

"Yes, yes, I will!"

Hearing this, Chu Guang's face finally showed a smile.

"That's OK. By the way, you shouldn't suggest that we choose by ourselves?"

Sun Shiqi was stunned and looked at the man in front of him.

"Wait, what do you mean by choosing yourself?"

Chu Guangli said of course.

"You can't apologize empty handed, can you? Otherwise, how did the apology come from? We won't deceive you. At most, we can pick something from your cow's back."

Speaking of this, the smile that had previously appeared on Chu Guang's face gradually collapsed.

"You won't... Hate it?"

Sun Shiqi's face was more ugly than crying, but he still hardened his scalp and nodded his head.

"No! Everything is in this car... You can choose."

These bandits!

As a civilized person's reserve and pride?

Rob a ragged waster!

It's like a rich man robbing beggars on the roadside. Won't these people blush for their actions?

Shivering cold!

Sun Shiqi scolded maliciously in his heart, but his face was still smiling and dared not show any negative emotions.

He has gradually begun to realize that there seems to be an essential difference between this shelter and the one he has met.

As for Chu Guang, he didn't care what the merchant was thinking.

Because it doesn't matter.

Seeing this guy so sensible, a happy smile reappeared on his face.

"Then I'm welcome."
