I became a planet

Chapter 24 Fatal Weakness
Guo Sen was also a curious young man.

When he was in college, he joined a society composed of strange people who were as obsessed with ore as he was. In order to prove that he could, after reading some popular science articles, he excitedly experimented with copper smelting by the river.

The process was a bit arduous, but the results were rich.

After several experiments and falsifications, he fiddled with a lot of copper blocks, and even made a copper block to give to his favorite goddess.

Of course, the opponent almost beat him to death with that brick.

Guo Sen later withdrew from the society because of this, hiding his achievements and fame.

The experiment is actually very simple.

The first step is to dig a pit for firewood, put charcoal, then put malachite powder, and then cover with a layer of charcoal.

The second step is to take out the blower and connect an iron pipe, and insert it into it.And find a piece of wet turf to cover it, and then use the mud from the river to block the gap to make an air outlet.

The third step is easy.Use a blower to continuously inject air into it for several hours, and pay attention to the color of the flame.

Finally, pour water into the carbon pit, pick out the copper with wooden clips and rinse it. (Good boy, please do not imitate)

This utilizes a redox principle.

Charcoal burns to produce carbon monoxide. After covering the high-temperature-resistant wet turf, the wind blowing inward from the blower will increase the temperature inside, forming a very simple furnace.

Long-term air injection will produce a redox process at high temperature. Carbon monoxide combines with oxygen in malachite to generate carbon dioxide and metallic copper.

Primitives who didn't even know fire certainly didn't know this chemical reaction.

Guo Sen didn't expect that it would come in handy at this time.

Using wooden sticks to hold the still hot copper, Guo Sen led the crowd to the river, and brought some river water to wash it and cool it down.

Metal that shone the color of fire, shimmering and glowing in the light of the stars.

The lizard people were stunned.

Who has seen such a thing!

Besides, didn't the leader just throw the green powder into the fire before, what the hell is this red thing?

"You guys, use the method of making the tip of the gun to make it into the same shape!"

At Guo Sen's order, a few short lizardmen came out immediately, picked up the copper block as if holding the moon, and picked up a few black stones to make them.

After a while.

"Boss, this is..."

The old lizardman saw things he had never seen before.

It obviously has the shape of a stone spear tip, but it feels sharper!

The shining light was enough to blind his eyes!
The tip of the gun was quickly tied to a wooden stick and handed to Guo Sen.

Taking his new weapon, he drew an arc into the lush grass by the river.

In an instant, the grass was broken in two!

Guo Sen easily cut through the freshly peeled animal skin and cut it into pieces!
Guo Sen was very satisfied, the sharpness of the tip of this gun is really not covered.

Seeing this, all the lizardmen quickly knelt down.

They all confirmed their eyes.

Who the hell said to overthrow our boss, I'll be the first to kill him!

The blades made in this way are much stronger and sharper than stone blades.

However, Guo Sen still needs actual combat experience to let these simple-minded lizardmen know how good metal is.

"Okay, just do what I did before, and get some more of these things out!"

Guo Sen gave the order, and soon, the lizardmen, headed by those hunters, began to follow suit.

One after another, round pits emerged one after another on the flat ground of the square.

While they were digging the pit, Guo Sen piled up a half-meter circle of rocks in the center of the square, threw a large pile of dry branches and dry grass, and threw the piece of magma into it.

The flame rose into the sky with a burst of thick smoke and then ignited. Now, the bonfire as the kindling seed is also ready.

"Okay, come and find some more wooden branches and sticks, and put them into the fire for me. After they turn white, put in more wood. Remember to try to dry as much as possible, you hear?! "

The next step is to let these guys protect the fire source so that the fire will not disappear easily.

"Boss! The subordinates understand!" The old lizardmen beckoned, and some lizardmen immediately ran away to work.

Guo Sen looked at this old guy and thought to himself, you are so lazy, you will order others to work.

However, Guo Sen also noticed that from the very beginning, he had been staring at himself doing those things. When making the bonfire, the old lizard man even went to the malachite powder to study for a while.

If he can summarize these skills and teach them to other lizardmen, he can save himself a lot of trouble.

The profession of teacher must exist from now on, and Guo Sen thinks that this old lizard man should be qualified to be the first official teacher soon.

"Come here." Guo Sen beckoned to him.

"leader?"

"Did you see the whole process of my weapon making just now?" Guo Sen asked.

"Yes, chief."

"Go, tell them how to do it." Guo Sen pointed to the hunters who had forgotten how to smelt copper.

The old lizardman nodded, and immediately began to guide the hunters.

Light a fire, put charcoal, put malachite powder, put charcoal again, make wooden cylinders...

Every step, this old guy remembered very clearly.

The hunters quickly became familiar with this somewhat complicated process under his tireless teaching.

Soon, irregular blocks of copper that shone brightly were produced.

Then, after the female lizard who had been waiting for a long time helped people cool down the splashing water, they began to polish it with rocks.

The sun was setting, and after a while, more than ten bronze spear points were made again.

Guo Sen originally wanted to ask the hunters to go to the forest to test the power of the bronze gun, but he discovered something unexpectedly.

All the lizardmen gathered around the bonfire, and even the guards at the gate closed the gate, and they all ran over.

Guo Sen was a little puzzled at first, but he quickly sat down with his arms folded until he felt the cold air continuously invade the skin inside the scales from the outside.

Reptiles are ectotherms.

When the temperature is lowered, various functions are also reduced, and the body temperature will gradually drop.

Even the original mighty batch will immediately turn into chicken after encountering the cold.

It never occurred to Guo Sen that the lizardman still had such a fatal flaw.

He vaguely remembered that this continent was located in a low-latitude subtropical region, and in this kind of weather, it would still be a little cool at night.

This sudden drop in temperature also restricted the activities of the lizard people.

The bonfire crackled and burned fiercely. The lizard people attracted by the temperature cuddled up to each other and gradually closed their eyes.

Guo Sen knew that, let alone going hunting, he didn't even want to move.

Using his mind, he began to move this piece of land to lower latitudes.

In this way, the lizard people in the tropics may not be able to rely on flames to keep warm when night comes.

　Thanks to book friends Smiling Sunshine, Long Bow, Durian Conch and Lion Powder, and Big Devil’s Scallions for rewarding 100 coins!
　　Thank you all!
　　This book is written to the 24th chapter, and everyone should be able to see what kind of planet I want to write about, right?
　　Unlike the books on evolution written by the big ones, the progress of this book is unusually fast, and it has evolved from single-celled organisms to low-level intelligent organisms in three or two steps.

　　It would be boring to imitate the detailed process and steps of evolution written by the masters, after all, our level is limited.

　　Thanks again for everyone's support!
