Douluo Continent: Palace of Seven Kills

Chapter 4 Making a Mirror

As the saying goes, the children of the poor are in charge of the family early. Although Liu Xin has only been here for five years, and the people in Shitou Village don't let her do anything, Liu Xin, who is far beyond the mind of a child, can see the sadness of the adults.

The more he watched, the more Liu Xin felt proud of the original world, and even more proud of his motherland.

You know, not everyone is strong!
In Douluo Realm, those who are not strong can only be trampled by others, but it is different in the original world, it can rely on knowledge to change fate, so that everyone has a chance to stand up.

Even if knowledge is placed in the world of the strong in Douluo Continent, will it really be bad?

In Liu Xin's heart, the answer is no, that is the pride engraved in his bones.

She believed that if the chemical knowledge she mastered was used to kill the enemy, it would be no less powerful than some soul skills.

So when Tang San asked about her original world, although some things would be exposed, she would still proudly say, "That is a world full of knowledge."

Tang San asked: "What kind of knowledge?" He happened to understand the traveler in front of him clearly.

"This... I won't be able to tell you clearly for a while. How about it, do you have a metal called aluminum at home?"

Since he said that he had seen some of Tang San's experiences, then I'm afraid that he also has to find out.

Otherwise, with Tang San's intelligence, he probably wouldn't let him go easily.

Tang San said in astonishment: "Aluminum? This is... you mean soft gold? Is it a metal that is not very hard but can be fused with other metals to make the finished product more durable? There are many of this kind in my family, and my father made it. Farm implements are never used. Compared with it, fine iron will be harder and more durable."

Tie Jing was of course Tang San's father, Tang Hao, who refined common metals with the Chaos Cloak Hammer method.

Its quality is unquestionable, but unfortunately, the chemical properties of this metal are relatively stable, and chemical reactions are not easy to occur.

Liu Xin smiled, laughing at a big idiot, "Who told you that I want to refine metal? Get it quickly, so that you can experience the power of knowledge. By the way, I also need some flint, wood and some scrap iron piece……"

Perhaps seeing the change in Liu Xin's expression, Tang San really pretended to be ignorant. Today, no matter what, he must also show Liu Xin's strength.

While scheming Liu Xin, he was actually quite curious. In his impression, metals were used to refine, make agricultural tools and make hidden weapons.What power is there to make metal have other uses?

"Okay, I'll go right away, I'll be back soon, and don't even think about running away."

With that said, Tang San cast Ghost Shadow Bewildering Trace, and with a "whoosh" his figure was tens of meters away.

"Cut, me? Will you run away?" Liu Xin stuck out her tongue in the direction Tang San left.

After tidying up the tattered clothes and sitting cross-legged, Liu Xin's thoughts were brought back to the scene of that night three days ago.

"Fate? Favor?" Liu Xin seemed to hear these two words in a panic.

It seemed that fate really favored her, if it wasn't for the spirit beast making mistakes one after another before she could react, if it wasn't for Bibi Dong's timely action, she would already be a corpse now.

"Hey, why did Pope Bibi Dong of the Wuhun Palace come here? Who is the elder sister she mentioned? Or is she already dead, it doesn't seem to be mentioned in the original book? Or is the plot changed because of me? Hey, Difficult to do..."

After about a stick of incense, Tang San ran back, still twisting a sack in his hand.

"Hey, this is what you want." Tang San lifted the sack in front of Liu Xin while adjusting his rapid breathing.

After taking the bag and taking out the contents for a look, Liu Xin's expression changed instantly, and his delicate little face became a little more focused.

"Alright!"

No longer looking at Tang San, at this moment, Liu Xin's heart has completely calmed down, and only the experimental materials are in his eyes.

Take out relatively large and smooth pieces of iron from the bag, wash them in stream water and lay them flat on the ground to dry.

Then take out the protagonist of this experiment—aluminum, and a sharp piece of iron, which rubs against the surface of the aluminum quickly.

The hardness of the aluminum block is much smaller than that of the iron block. When the two grind together, the aluminum must change first.

Soon, the aluminum gold that was originally in the shape of a square was ground into powder.

Liu Xin skillfully collected all the aluminum powder and evenly spread it on the smooth iron block that had just been washed.

She set up a small wooden frame for the wood in the sack, put the thick ones outside and the thin ones inside, and flint and steel were placed at the bottom.

Everything is ready, the difference is the response!

Pick up another piece of flint and collide with the remaining wooden sticks, and with a bang, a flame will appear on the top of the wooden sticks.

Fire is the most common thing in experiments. Liu Xin just took the wooden stick and ignited the wooden frame.

Then calmly put the smooth iron block with aluminum powder on the shelf to heat the aluminum powder.

Heating removes the oxides contained in the aluminum powder, giving it more chemical properties.

After a while, the oxides were removed, the aluminum powder was already in a molten state, and the surface refracted the sunlight, making it particularly glaring. The ability of aluminum to emit this kind of luster really opened Tang San's eyes.

Then put the burning wood on the molten material to make it burn and react completely.

Liu Xin has done this kind of experiment many times. He has rich experience, and he knows that the reaction is complete without looking at the time.

Quickly pour water to extinguish the flame under the wooden frame, and let the iron block covered with aluminum-gold melt stand still and cool down.

This last step takes the longest time, Tang San went over to look at it several times, but didn't find any clues.

"It's time!" Liu Xin's crisp voice sounded, Tang San quickly cheered up and watched Liu Xin's every move intently.

The liquid-like melt disappeared, and on the iron sheet was a transparent surface, which clearly reflected Liu Xin's appearance.

"This is! What a clear mirror!" Tang San looked at Liu Xin in surprise, and then at the iron piece, what's going on?What about aluminum?so amazing?Is it magic?
Tang San never thought that a piece of aluminum metal that is not very valuable in Douluo Realm can be made into a priceless mirror!

You know, there is no modern mirror-making technology on the current Douluo Continent!
Those mirrors are mostly made of marble or copper metal, and of course, there are also mirror-shaped soul guides.

No matter what kind of mirror it is, its price is very high!And except for the soul guide, it is definitely not as clear and thorough as the one made by Liu Xin!

But, it seems that the cost of this mirror seems to be very low!

"Hey, don't be surprised, these are what I call knowledge! How is it? Do you feel the power of knowledge?" Seeing the surprised look of the protagonist Tang San, Liu Xin was quite proud.

"Give these mirrors to you, and you can sell them to some merchants in the village for a good price! Uh... take this as some compensation from me!"

"Hmm..." Tang San answered absently, but he kept repeating "knowledge...knowledge..."

The mirror experiment was not offensive at all, although Tang San was greatly shocked by "knowledge", the string in his heart was let go.

It was years later that he realized how stupid he was to pass up such an opportunity.

Because the "knowledge" Liu Xin displayed at this moment is just the tip of the iceberg.

……

The mirror was sold to merchants in Holy Soul Village at a much lower price than ordinary mirrors, even so, Tang San also made a lot of money from it.

Because of this, Tang San's food and other aspects improved in the next few days, at least a few pieces of meat could be added to the original porridge.

Also because of the low cost of mirrors, good sales, and more customers who want to buy, the businessman selling mirrors approached Tang San, wanting to "purchase" again.

Hearing Tang San talk about this matter, Liu Xin immediately agreed, and made another pile of mirrors that day, and asked Tang San to resell them, and the money they got was shared equally.

This is also a good thing for mutual benefit!
The sale of the mirror gave Liu Xin a certain amount of savings, so he could eat, drink, have fun, and prepare experimental materials.

Every morning, as a "rich man", Liu Xin would go for a walk in the market next to the village.

In his previous life, Liu Xin had done some research on the physical and chemical properties of chemicals. Naturally, it was not difficult to find these raw materials in Douluo Continent.

In the market, in addition to the necessary food and clothes, Liu Xin also harvested many chemical raw materials.

Whenever Liu Xin swaggered to the market to buy some worthless powder in large quantities, the people in the market would look at her very strangely.

"What a girl, why is she an idiot?"

"Are you sure you want to buy this?"

"A copper soul coin, take it away..."

……

Regarding these remarks, Liu Xin just smiled and said nothing.

They don't know how to use them, so they feel that these materials are worthless, but Liu Xin knows, those things are treasures to her.

No matter how expensive it is, it is worth buying.

These chemical materials will be made by Liu Xin into some extremely lethal chemical weapons.

After experiencing rebirth, she has been a baby for 5 years, and the road to Douluo is about to start. Before that, she must make full preparations!
……
