The Primitive World of Planar Trading

Led by Xing, Wu Nuo came to this land of death that was deeply feared by the residents of the Changhe tribe.

"This is... a swamp?" After half a day's "long-distance trek", Wu Nuo finally stood in front of a low cliff and saw the whole picture of the land of death - a mud lake so big that you can't see its edge at all. The water vapor on the dark gray mud lake was steaming and cloudy, and large and large mud bubbles were constantly rising. From a distance of hundreds of meters, everyone could feel a trace of obvious heat and a strange smell of mud.

Not a single blade of grass grew in the area around the lake or in the mud lake. A wild bird flew from nowhere and flew over the mud lake at low altitude. It fluttered its wings and struggled desperately, but its struggle did not have any effect, and the more it struggled, the faster it sank, and it was completely swallowed up by the mud lake in the blink of an eye.

Witnessing the whole process of the bird being devoured, Wu Nuo couldn't help swallowing, no wonder this place is called the place of death!The steaming soil inside is probably much viscous than the cold one brought back by Xing.

"Swamp? What's that?" Star asked.

"We call this kind of place a swamp, but the place of death is not the same as our swamp." After Wu Nuo explained, he asked again: "Is the soil you brought back to show me earlier from this place?" From the swamp?"

Long before coming here together, Wu Nuo had already learned the detailed information of this clay through the system.The system named this clay 'ultra-sticky mixture', which is a very rare natural mixture.The special feature of this kind of clay is that there is a very small part of its mixture but the key ingredients only exist in the early stage of the planet's gestation, unless it encounters an extremely special geological environment, it is difficult to preserve these special substances and eventually form' super viscous mixture'.

Among the tens of thousands of living planets connected to the system, only a few dozen living planets still have this substance.

However, although this mixture is extremely rare, it is not very valuable, because there are not too many "extremely special geological environments" on non-living planets _(: 3ゝ∠)_

Because Wu Nuo paid a full 100 points of 'information fee', the relevant information given by the system is very detailed. The information shows that someone has used this 'ultra-sticky mixture' for construction, and the effect is very satisfactory. There are some very lofty uses, but it's a pity that Wu Nuo can't use them.

Xing nodded and said, "The soil in the Land of the Dead is very special, it can stick stones together."

"Can it really stick the stones together?" The soil that Xing brought back was indeed very sticky, but it wasn't enough to stick the stones together, right?

"When you put hot earth on a stone, the earth cools and hardens, and the stones stick together."

The land of death is a forbidden place that everyone talks about in the Changhe Tribe. Even in the coldest winter, it is still warm here, and no animals come here. If it is rotten and falls into the lake, it will disappear without a trace in the blink of an eye.When the ancestors of the Changhe Tribe migrated here, they passed by the Land of Death. At that time, a little orc cub accidentally fell into it. His parents ran to save him, but instead of saving him, he collapsed. More than a dozen tribesmen went in.This tragic story has been passed down from word to mouth in the tribe, and it has been passed down to this day. If the cubs are too naughty and disobedient, their parents will threaten to throw them to the land of death. In his bones, he was not even willing to go in this direction.

Although Xing is a pure person, he has been dishonest since he was a child. He has a lot of courage and ideas. When he was very young, he sneaked here with his elder brother Liliu to see it. At that time, he happened to see a stupid rabbit running too fast and fell into it. In the mud lake, they disappeared without a trace in the blink of an eye. The two little guys were terrified. After returning, they dared not mention that they had been to the land of death.

Later, Xing grew up, and because of curiosity, he came here several times.

By chance, he discovered that the hot mud in the land of the dead can stick stones together, but it can't do it when it's cooled. The cold mud will become harder and harder, and finally it's almost as hard as the rocks on the shore.

He once tried to persuade everyone to use the strange soil here to build houses, but everyone was too afraid of the land of death, and would rather be frozen in winter than use this kind of soil to build houses. He disagreed, and also said that the soil in the land of the dead is poisonous, and it is the residence of demons. Even if the house is repaired, it cannot be lived permanently. In the end, it can only be left alone.

This time, when Wu Nuo said that he was looking for a kind of soil with strong stickiness, the first thing Xing thought of was the soil in the Land of the Dead.With the mentality of giving it a try, he dug a piece back and gave it to Wu Nuo, but he didn't expect Wu Nuo to come here with him without saying a word after reading it.

After listening to Xing's description, Wu Nuo muttered in a low voice, "Why does it sound like cement? Could it be used as cement?" If it is true, it will solve his big trouble.

"Come on, let's go and have a look." Wu Nuo said.

Xing said: "The shore is very dangerous and poisonous. If you want soil, I can get it for you."

Xing has already told Wu Nuo about the poisonous soil, but according to the information displayed by the system, due to environmental factors, the area where the 'super viscous mixture' is located will produce some hallucinogenic gases to carbon-based life, but the mixture itself is It is safe and non-toxic.

Wu Nuo shook his head and said, "No, let's go together."

Seeing that Wu Nuo insisted, Xing didn't say anything anymore, but he had a little more affection for Wu Nuo in his heart.

In his opinion, Wu Nuo is capable, willing to consider for the tribe, approachable, willing to listen to and adopt different opinions, looks smaller than a pure female, but not delicate at all, no wonder all the old and young in the tribe like him.

As he approached the place of death, the hot and humid air became heavier and heavier. Wu Nuo covered his nose and tried to reduce the number of breaths, but after walking to the shore, he still felt dizzy unavoidably.

No wonder the bird fell into the lake just now, the poisonous gas is really powerful.

Thinking about it, Wu Nuo plunged a dry branch prepared in advance into the steaming 'soil', and a wisp of green smoke accompanied by the smell of burnt wood escaped instantly. It came from the other end, and in a moment, the branch fell into a small half.

Wu Nuo took a lot of effort to pull out the branch, and the hot dark gray mud adhered to the branch, constantly bubbling tiny bubbles, and it took two to three minutes for it to cool down slowly.

Wu Nuo took a little soil from the branch and rubbed it on his fingertips, the viscosity was indeed thicker than Xing gave him before.Wu Nuo looked around, picked up two thumb-sized gravels at his feet, and spread the gray soil on the gravels. After a while, the soil cooled down. Although it hadn't hardened yet, the two gravels were still Being firmly stuck together, Wu Nuo took a little effort to break the two apart.

Although Wu Nuo's knowledge level is limited, he still learned a little bit of basic chemical knowledge in junior high school. He guessed that the change of soil from soft to hard should be a long chemical change process.

However, since these 'super viscous mixtures' can form a substance as hard as stone after cooling automatically, is it necessary for him to let them go through the process of burning bricks again?

Wu Nuo's heart moved, and he called up the system control panel. The progress bar of the compulsory task on the above was 5% higher than that in the morning, and it stayed at 15%.

This means that it should still be burned, right?

As a cunning peddler who is good at observing market conditions and discovering business opportunities, Wu Nuo applied these observation skills to the system, and gradually, he was able to take advantage of small loopholes.

Wu Nuo rubbed his nose and stood up, ready to take another look around. Just as he stood up straight, his head buzzed for a moment, as if he saw a huge boa constrictor flying towards him in a trance. Staggering, he stepped on the ground and fell straight back. A force behind him grabbed him and dragged him back several steps.

"Sir, are you alright?"

Seeing Xing's anxious face, Wu Nuo finally came to his senses, where is there any sign of a boa constrictor around?Looking at the traces on the ground, Wu Nuo was so frightened that he broke into a cold sweat——

Almost, he almost fell in just now!

Wu Nuo: This world is so dangerous, I really want to go home qaq.

After a long time, Wu Nuo finally recovered, shook his head and said, "It's okay."

Seeing that his face was pale and there were big beads of sweat on his forehead, Xing knew that he must have been frightened just now.Xing seldom comforts others. The younger sister and younger brother in the family are very skinny. My younger sister Wen was the same as Ah Wei when she was young. She was the head of a child in the tribe. Poor, I don't know why I feel a little sour in my heart.He thought for a while, then patted Wu Nuo's head clumsily, and comforted him: "Don't be afraid, I won't let you fall."

Xing has already spent 23 cold winters, and he is not considered young in terms of the average age of a pure person.Last year, his only female died of dystocia during childbirth, and the cub that was born failed to survive the cold winter and died too.The death of the female and the cub dealt a great blow to Xing, so much vicissitudes were engraved in his eyes early.

Xing is tall, nearly 190 centimeters, with perfect muscular lines, and looks exactly like his mother Lan, but with a sense of fortitude. His dark skin makes him look wild and handsome.

Wu Nuo was a little embarrassed, wiped the sweat off his face, and said with a smile: "Thank you just now. The fog here can make people hallucinate, so you should be careful."

"Hallucinations? What's that?"

"The witch said that this is the dwelling place of demons, but it's not. It's just that there is a problem with the mist. After inhaling too much, the brain will have hallucinations and see things that don't exist." His physical fitness is much better than his, and he has a certain resistance to those gases, and he will not notice any abnormalities in a short time.

"...So that's how it is." Xing nodded half-understanding, "Then what your lord means is that this is not the residence of demons, and the soil is actually not poisonous, so it can be used to build houses, right?" Not only Xing, The eyes of the other two pure human fighters also lit up.

"Yes."

After confirming that the soil in the land of the dead can be used to build a house, it is time to consider how to get the soil.

Wu Nuo, Xing, and two other pure human warriors walked along the land of death for a long time, and finally found a low-lying land. Unlike the previous places that were all hard rock formations, here is not only a low-lying land, but also a slender Crack some soft soil.After discussing with Xing, Wu Nuo and Xing decided to build a ditch in this place, and some of the clay in the mud lake would be brought in.
