Master of Thermodynamics

Glancing at the corpses all over the floor, as well as the large and small thick wooden shields, Moose roared out new orders coldly.

"The whole team, ready to attack the village!"

The Island Guard team just repelled the second attack of the Black Orcs.

In this attack, the black skins adjusted their tactics. They all held a thick wooden shield and tried to use them to block bullets.

They also mobilized more people, with a total number of more than 500 people, including elderly people with white temples, children with significantly shorter heights, and even women.

Obviously, this black orc tribe is going to make a desperate bet.

This is also the first time many people have seen a female black orc with their own eyes, but after just one glance, everyone lost interest.

too ugly.

Like the black males, the female black orcs have the same blue-faced fangs, but the fangs that stick out from the corners of the mouth are slightly shorter and the body is more slender. If it were not for the surprisingly large bust, I am afraid that many people would not recognize them as females.

The result was the same as the first time, and the Black Orcs failed miserably again.

A thicker wooden shield cannot effectively block the bullet, but the penetration distance is shortened. The shield can be broken at a distance of 300 meters, but it now takes 200 meters.

But the disadvantages of using thick wooden shields are also great. Its weight is heavier, and it is inconvenient to walk with it, let alone running.

After the Black Orcs lost their speed, the island guards could take aim calmly, but their hit rate increased a lot.

As a result, the black orcs suffered more casualties than the first time. More than 200 people fell on the battlefield, and the only awakened person in the village also died.

More than half of the casualties occurred while fleeing. When the black skins retreated, they all discarded their wooden shields. By escaping with bare hands, the island guards could calmly shoot the black skins from behind.

After the two defeats in the two wars, this tribe was completely maimed. Almost all the mature males died in the battle. Only a group of old, weak, sick and disabled people remained in the tribe, unable to launch a new offensive.

There were only 3 minor injuries on the island guard team, and all of them were innocuous skin injuries, which had little effect on the battle.

After the Black Orcs retracted into the village, it was the island guard team's turn to attack.

Strictly speaking, it should be called arson.

That is to burn the wooden houses in the village one by one. If the black orcs in the house rush out, they will be shot to death. It doesn't matter if they don't come out, it can save a few bullets by burning them inside the house.

This is the three-light policy of the alien version.

No, two lights, kill all and burn all, because there is nothing to grab the black orcs.

In order to quickly set fire, the island guard team also used a new prop-Molotov cocktail.

The light oil distilled from the black oil is mixed with the thermite, that is, aluminum powder and iron trioxide powder, and then a neutralizer is added, which is a resin mixture that can increase viscosity and support combustion. The final combustion The agent is done.

Finally, the liquid is filled in a mass-produced ceramic bottle, and the combustion bottle is made.

This is also the best formula found by the magicians of the Rune Research Institute after hundreds of trials under the advice of the lord.

The preparation of aluminum powder is very simple. Throw the feldspar containing aluminum into the magic aluminum smelting furnace to easily obtain aluminum. After grinding the aluminum ingots out of the furnace, the aluminum powder will be available.

On the earth, the process of preparing aluminum powder is dangerous, because aluminum powder is extremely easy to oxidize, and extremely small aluminum powder particles are suspended in the air, and the contact surface area with the air is greatly increased. Once the dust reaches a certain concentration, it will encounter a source of ignition. There will be a violent deflagration.

An accident like this occurred in Huaxia. In a factory that processed aluminum car wheels, a large amount of dust was generated when polishing the wheels. In addition, the ventilation conditions were extremely poor. Unfortunately, an aluminum powder explosion occurred, which eventually caused more than 200 casualties. The price is very heavy.

But in this world, there is no such worry at all. Hydrogen can't blow it up, not to mention a little aluminum powder, don't worry about grinding it boldly, if it can be blown up, Renault dare to change the name to Dongfeng Renault.

As for the reason for this weird phenomenon, Renault has a conjecture.

As we all know, combustion is actually a violent oxidation reaction. During the oxidation process of combustibles, a large amount of heat is released rapidly, causing the gas to expand violently and explosion.

But in another world, during the oxidation reaction, the speed of electron loss is suppressed by magic energy, resulting in the burning speed being greatly slowed down. The noise caused by the "deflagration" of aluminum powder is not much louder than the "fart", and it is absolutely impossible to explode. Dead people, it's possible to choke people to death with dust.

Feldspar is also very easy to obtain. On the earth, aluminum is the most abundant metal element in the earth's crust. The proportion of feldspar in the earth's crust is as high as 60%. The source is very wide, and the same is true in other worlds.

When using magic aluminum smelting furnace to smelt aluminum, a large number of by-products are also obtained, far more than steel smelting, including but not limited to sodium, calcium, silicon, potassium, barium, and many other isotopes.

However, sodium and calcium are relatively valuable on the earth. Take sodium as an example. The earth needs to be manufactured by electrolysis. The high energy consumption leads to high prices. How can one ton of metallic sodium cost tens of thousands of soft coins?

But in Haichao, once the magic energy decomposition method is opened, there will be as much metal sodium as it needs. A lot of them are cheap. How cheap is the price?

It is cheap enough to be used for mass production of caustic soda, which is NaoH.

As the most important chemical raw materials, three acids and two alkalis, one of them, caustic soda, was solved in this unexpected way.

On the earth, there is absolutely no fool who will use this method to make caustic soda. Even if it does, the price will break through the sky. Who can afford caustic soda for dozens of dollars a pound?

This kind of weird "sodium metal soda method" can only appear in other worlds.

With caustic soda, soda ash (Na2Co3) is a trivial matter. It is enough to pour carbon dioxide (Co2) into the caustic soda solution.

The uses of caustic soda and soda ash are extremely wide. Caustic soda can be used to make paper, soap, dyes, and rayon.

Soda ash has more uses. One of its main uses is glass. It can also be used in the food industry, such as steamed bread and bread. Adding so-called alkaline noodles to flour can neutralize the sourness produced during fermentation. Improve the taste.

The effect of the Molotov cocktail is surprisingly good.

Every time they saw a wooden house, the island guards would take out 3 or 4 Molotov cocktails from their backpacks, slam them on the surface of the wooden house, and then throw a few torches over, and the violent fire would instantly rise.

Thanks to the characteristics of light oil, the burning speed is very fast, coupled with the effect of the thermite, the heat released is also surprisingly high, standing 6 or 7 meters away can feel a strong burning sensation.

With the rapid burning and high temperature, other parts of the wooden house were quickly ignited, and then the flame spread to more places. The whole wooden house quickly turned into a giant torch, and the flame tongue rushed more than 10 meters high.

Then, boosted by the wind, the flame tongue licked the neighboring wooden houses and ignited these wooden houses by the way. The fire turned into a sea of ​​flames.

Watching the wooden houses being swallowed by fierce flames, listening to the miserable howls inside the houses, and the crying cry of the children with horror, and occasionally black orcs who were on fire rushed out of the wooden houses, crying and crying. The scene looks extremely cruel.

However, none of the arsonists of the island guards expressed sympathy, and many of them showed obvious happiness on their faces.

Everyone knows the sins the black orcs have committed against this land. The more miserable the black orcs, the more they feel happy.

Even the natives on the Haichao Islands who knew little about the black orcs, after learning about the tragic experience of humans on the mainland, hated the black orcs from their hearts.

Since the black orcs invaded the human kingdom and wiped out the humans on this continent by means of genocide, both humans and the black orcs were destined to fall.

Either humans die, or black orcs die, there will be no second possibility.

During the period, it was not that no black orcs tried to stop this "evil deeds". The black skins in the tribe had also organized several counterattacks, but this approach had no effect other than sending people away.

Under the volley of magic air guns, they could not even approach the island guard team within 50 meters. Every time they rushed halfway, the black skins could no longer bear the heavy casualties and turned around and fled. The corpse dropped to the ground.

After more than one hundred guards of the island wandered around the village, the whole village was completely surrounded by the sea of ​​fire, and the billowing smoke drifted away with the wind, smudging the sky with a hint of ink, even under the cover of snow, ten This scene can also be seen from a few kilometers away.

In fact, this kind of crazy arson method is quite a waste of suspicion.

Although this black orc tribe is very poor, there are definitely a lot of black crowns and warriors in the tribe. There must be many valuable objects in their homes, such as various gold and silver objects, or black orcs' gold coins, silver.

It's a pity that the Island Guard team didn't have time to search from house to house in a hurry, because no one knew how fast the other black orc tribes reacted.

Before evacuation, the island guard team has one last thing to do-rescue human slaves.

The camp for human slaves is located in the southwest corner of the village, more than 400 meters away from the village.

When the action plan was made, everyone thought that the black orcs would distribute human slaves directly to the black skin family. If so, this would bring huge trouble to the rescue of slaves.

But to everyone's surprise, the Black Orcs did not do this, but chose to use the human slaves together.

It is the black orc slaves who are really assigned to the black skin family. When the island guard team sets fire from house to house, they can often see some shabby slaves rushing out of the wooden house.

After walking along the snow-covered path to the front of the camp, only one glance, everyone felt that this group of slaves was too miserable.

The shack in the camp is generally very low, including the roof, and the height is only one person high. In the house, even the body cannot stand upright. The outer walls are all adobe walls, and the roof is made of wooden boards randomly put together.

This kind of shack has only minimal protection from wind and rain, and almost no warmth. In such a cold winter, the temperature inside the house is not much higher than outside, and it is not known how these human slaves survived.

The smell in the camp is not very good, even if the howling cold wind can't completely sweep away the remaining smell, the team members can still smell a faint smell.

It can be said unceremoniously that there is no difference between this camp and the livestock barn.

There is a large wooden fence around the camp, and several guard towers are scattered around. There is no one on these guard towers. Obviously, the black orcs who guarded the slaves saw the situation in a bad way and had already escaped.

At this time, the slaves had realized that something had happened. In the shack, each head was poking his head behind the door, looking at the scene outside the camp.

"Everyone, we are the island guard team of the Haichao collar. On the order of the lord, come to rescue the human race..."

Moose's angry voice spread across the entire camp in an instant, and immediately after he signaled, the island guards also yelled in unison.

"We are the island guard team of the Haichao collar. By the order of the lord, we will come to rescue the human race..."

...

In the shouts over and over, the ragged slaves hesitantly pushed open the low wooden door, walked out of the shack, and looked at the island guards through the fence.

When the number of slaves gathered in the open area of ​​the camp approached 300, an island guard walked out of the crowd, took off his helmet, and pushed open the gate of the fence.

With the sound of the "creaking" wooden door turning, he slowly walked into the camp.

Facing a pair of eyes full of expectations, desires, doubts, fears and other emotions, he took a deep breath and shouted loudly.

"Everyone, you are free!"
