C5 Distillation Process

Chu Dong was not the person who was exterminated.

However, Chu Dong's memories of this world remained the same.

Although it was broken and messy, it allowed Chu Dong to have a clear understanding of this prehistoric world that was countless tens of thousands of years old.

Primitive, desolate, and barren.

The existence of the dinosaurs and Giant Beast and giant insects had filled the world with danger.

Coexisting with the dangers was the shortage of food. His Rock Tribe was much stronger than Chu Dong's from before, a small tribe with more than five thousand people by the banks of the Blue Sand River.

But even so, every time the rainy season changed, a large number of clan members would still lose their lives. In winter, even confident people are not 100% sure they can make it through.

Salt is the most common thing in modern society.

However, in the prehistoric tribes, it was extremely precious.

Every year, Rock Tribe required the consumption of a large amount of food in order to be able to exchange for a small amount of salt from the mid-sized tribe, Yun Shan's tribe. Due to the anxiousness of the food, they could only barely provide warriors who could hunt Vicious Beast for food.

Thus, ordinary clansmen had never tasted salt before.

How could he not eat salt?

Chu Dong muttered in his heart.

Even ordinary people knew the importance of salt to the human body's function, let alone Chu Dong, a doctor.

Salt ingestion was not only a condiment to the human body, but also guaranteed the most basic metabolic balance. For Chu Dong, salt is more germicidal and disinfectant.

This was common knowledge.

Chu Dong did not want to be operated on again in such a terrible situation. The axe was alive, and that was due to the axe's tenacious vitality. Who knew how many kinds of prehistoric bacteria there were, or how abnormal they were, and whether they would take the lives of these Primitive Man s.

However...

"Potassium chloride should exist in the prehistoric world. I wonder how far it is from the seaside. "Even though I'm a doctor, I still haven't returned the high school chemistry back to my high school teacher …"

"Hmm, with potassium chloride, I can give it a try when I make salt."

Chu Dong muttered as he pinched his chin.

"Chu …" You said … You can make salt? "

Chu Dong was deep in thought when he suddenly heard a surprised and uncertain voice behind him.

Next.

Chu Dong's neck tightened, and he was immediately pulled to his feet. He turned around and saw Chief Gaang Gu, fully dressed, standing in front of him, his eyes as round as brass bells.

From the looks of it, it seemed as if they wanted to eat him alive.

Damn, again?

This was the third time he had been carried away like a little chick.

This man was over 1.9 meters tall and was considered small in the eyes of society. However, in the prehistoric era, he was considered short when compared to the large men who were over two meters tall.

Chu Dong rolled his eyes and felt like retorting.

However, Chu Dong tactfully swallowed the insult that came out of his mouth when he saw the chief's wolf-like expression.

"It's not impossible for me to make salt, but the current conditions are still not ripe. If I have the materials and things I need …" I can give it a try. According to my calculations, it should not be a problem. "

Chu Dong struggled to get away from the chief's hand. Then, he thought for a while and replied.

"This... "Really?"

The chieftain's tall body stood in front of Chu Dong, his eyes bloodshot.

"Don't worry, it won't be a problem."

Chu Dong made an OK gesture as he pondered about the feasibility of the matter.

It was not difficult to make salt.

It was just the simplest purification and distillation process. Normal high school students wouldn't have a problem with that. As a top student who graduated from medical school, Chu Dong felt confident in his ability. Others could do it, but there was no reason why he couldn't.

The chief stared at Chu Dong without blinking and gradually revealed a smile.

He did not understand Chu Dong's gesture, but this did not prevent the chief from understanding his expression. Gaang Gu opened his mouth wide, revealing a mouth full of yellow teeth. He looked extremely happy.

Even Ma Xin, who was standing to the side, was extremely excited. He was so excited that he nearly danced in joy.

Rock Tribe was a small tribe. To be able to extend the tribe's existence required a large amount of food. However, in a dangerous environment like the prehistoric era, food was the most difficult thing to obtain.

But how could they not know how important salt was to soldiers?

Unfortunately, every time the tribe used up a large amount of food in exchange for salt, the soldiers would be forced to eat it. This made the tribe's food extremely limited, and the salt had always been in the hands of the big tribes, but every piece of food represented the lives of the people of the tribe.

And now, Chu said he could make salt?

Whether it was true or false, it was worth the tribe putting 120% of their attention into it.

"Good, good, good! Chu, you really are the lucky star of our Boulder. First, you saved the axe, and now you can make salt. As long as you succeed, no matter what you want, the tribe will do their best to cooperate with you. "In the future, Chu, not only will you be able to eat meat, your tribe will also not forget your contribution."

"Berserker Bone, the tribe can provide you with a piece of Berserker Bone. It will give you a chance to join the Hunting Wasteland Team and become a warrior of the tribe. You will fight for the honor of the tribe."

Gaang Gu's expression was dark as he looked at Chu Dong with an unprecedented seriousness.

Barbarian Bone.

The chief's promise could not be underestimated.

However, Chu Dong was so angry that his nose almost went crooked.

God knows how many dangers lurked in this barbaric prehistoric age. Chu Dong hadn't stepped out of the jungle yet, so he could only barely get a glimpse or two through the broken memory in his head.

Savage, primitive, and dangerous.

This was not a world that he could outline with his modern thinking.

What's more, the wound on Axe's body that could pierce through the chest was closed by Chu Dong himself. Chu Dong didn't think that his small body would be safe and sound since even the strong and sturdy men like Axe were severely injured.

According to his thoughts, he would rather lock himself up in the back and wait for his death.

To join Hunting Wasteland Team?

Become a warrior?

God only wanted to become a warrior.

Chu Dong held back the urge to ridicule and immediately looked like he had just eaten sh * t. However, the chief's promise was not without temptation. Chu Dong was curious about something as mysterious as the Barbarian Bone; it had some value in research.

"Don't worry Chief, this is just a small matter." I can assure you that as long as you can get me potassium chloride, I can guarantee that I can get you salt. "Hmm, don't look at me like that. I know you don't know what potassium chloride is. Let's put it this way. You can activate the tribesmen to go find salty water."

"Like I said, as long as you get the thing I want, there's absolutely no problem in making salt."

Chu Dong looked at Gaang Gu's stupefied expression and explained in a very understandable manner.

The chief was stunned for a moment. He opened his mouth as if he wanted to say something.

Salt was too important to the rock.
