His kitten demon is very coaxing, sometimes a meal can satisfy her, a hug can make her happy, she does not have high material requirements, she wants spiritual care.

"Don't worry, Xiaochen, I'm not the kind of demon who can't walk when I'm full. Xiao Jiu'er's digestion was very healthy, and soon her somewhat bulging belly became flat again, and she dived into the water with Shen Lihe.

"My little kitten demon, you always bring me joy and satisfaction. Wang Chen watched Xiao Jiu'er and Shen Lihe dive into the water, and the doting in his eyes couldn't be hidden.

Deng Xiaoxing was still in the water, and after he ate the whale shark, he went directly to mining.

More than 100 hectares of pyrite are distributed, and it takes a long time for the three demons to dig together, and Wang Chen took advantage of this time to make strong acid.

Because there is no antimony and fluorine, there is no way to make super magic acid, so Wang Chen can only retreat to make perchloric acid.

The sodium perchlorate method adds water to the sodium chlorate in the dissolving tank, dissolves it at 45~50 °C through steam, saturates it, and then adds barium hydroxide to remove impurities such as chromate, and sends the clear liquid to electrolysis to prepare sodium perchlorate. Sodium perchlorate is added to the reactor, and then 31% hydrochloric acid (the dosage is 110%~120% of the theoretical amount) is added for metathesis reaction to generate perchloric acid, and the sodium chloride crystals are removed by filtration, and the filtrate is evaporated and concentrated to more than 60% of the perchloric acid content to prepare industrial perchloric acid.

This method of making is too slow and cumbersome, and the production of sodium chlorate is also very cumbersome, Wang Chen didn't plan to do that, he has a super compression ability, and he can forcibly press the atoms together without separating.

Wang Chen flew to the sea, scooped a pot of seawater with the iron sulfur pot, boiled it on the fire, filtered out the lime sand inside, and crossed it into the true qi to make electricity.

The formation of electric current is actually very simple, Wang Chen uses aura to cut through the surrounding air molecules, the molecules are broken into atoms, and the nuclei are separated from the electrons outside the nucleus, and the electrons and protons are separated, which can form an unstable current.

The entry of electric current disturbs the order between atoms, and water is decomposed into hydrogen and oxygen, sodium salt is electrolyzed into caustic soda and chlorine/gas, and chlorine/gas and hydrogen are combined into a misty white gas in a high-temperature environment.

Wang Chen released energy, wrapped these misty gases, sealed them into a basketball-sized energy ball, and created a channel at the distance between the sulfur iron pot and the energy ball, and these species gases continued to pour into the energy ball through the channel, and the energy ball was continuously compressed, gradually turning into a white ball.

The other hand released a ball of the same energy to envelop a space, and it also built a channel link with the iron sulfur pot, but this channel was nothing, it seemed to be an empty pipe, and the energy ball was transparent, and it looked like there was nothing.

The white mist in the original shrouded mist-like energy ball gradually liquefied and turned into a colorless transparent liquid of about half a catty, but the smell was extremely unpleasant and very pungent.

Another empty ball of energy changed, and a pale blue liquid half the size of the ball suddenly appeared in it.

Liquid oxygen, pure hydrochloric acid, made and done!

In the process of making, the iron pot constantly appeared light green liquid, and after a while, it would turn into a yellow liquid, and the iron pot became thinner and thinner, and finally a large hole was pierced in the bottom of the pot.

"These ferric chloride can't be replaced at all without silver, and these ferric chloride poured into the sea shouldn't cause any pollution, right?" Wang Chen poured all these yellow ferric chloride solutions into the sea, and the yellow solution disappeared like mud cows entering the sea.

After all, iron is not a heavy metal, and some trace amounts of iron are also needed in living organisms, and these iron salts should not cause any ecological impact.

As for the caustic soda inside, there is no need to worry, the alkali will deteriorate after encountering carbon dioxide and become a harmless carbonate, which is why the soil is always acidified and becomes a problem, not alkalization becomes a problem.

Salt is a very broad word to describe many metal compounds, such as sodium salts, calcium salts and magnesium salts.

The most common sodium salt is the table salt that is available in every household, and the most common calcium salt is marble, including the calcium tablets we eat, which are also calcium salts.

"Next, it's time for a strong oxidation operation. Wang Chen looked at the two blue and white energy balls in his hand, and leaned the two energy balls together with both hands, and the two energy balls fused with each other.

Immediately after, the substances inside were also fused together!

The blue and white colors inside boiled uneasily in this large ball of energy after the fusion, as if it would explode in the next moment.

Wang Chen crossed into the true qi and forcibly pressed oxygen and hydrogen chloride together, so that there was an oxidation (hydrogen chloride) reduction (oxygen) reaction between them.

The determination of redox reaction is very simple, and it is the oxidation reaction that loses electrons and increases the chemical valence.

On the contrary, it is a reduction reaction that gets electrons and chemical valence decreases.

Wang Chen knew that if you want to make perchloric acid, then you must have enough oxygen, because one hydrogen chloride molecule needs two oxygen molecules to be balanced.

After all, his current strength is not able to violate the law of conservation of matter, although new substances will be generated before and after the reaction, the total mass of these substances will not change. (Of course, after the gas runs away, the total mass will be reduced, but the conservation of matter will still not be violated)

Hypochlorous acid (HCIO), chlorous acid (HCIO₂), chloric acid (HCIO₃) and perchloric acid (HCIO₄) have one more oxygen atom at each order, and the oxidizing corrosiveness will also go up a notch.

As the strongest acid in inorganic oxygenated acids, although it is not as corrosive as aqua regia, which is the runner-up in acid, it is enough to depict rune arrows.

Soon, under Wang Chen's compression, the blue and white two-colored liquid in the energy ball gradually turned into a single colorless smoke-emitting liquid.

Wang Chen used the energy ball to completely seal the perchloric acid, squeezing out all the impurities inside, and once this thing is heated, it will explode 100% once it encounters combustibles.

Because it is a volatile liquid and a strong oxidizing agent, Wang Chen still keeps it in a sealed energy ball and uses it when he needs it.

After oxidizing it into perchloric acid, Wang Chen condensed the energy ball into a half-virtual and half-solid entity, and if it was not attacked in a short period of time, the energy ball would not disappear, and the perchloric acid inside could also be preserved.

After doing this, Wang Chen glanced at the garbage author who was recording, and teased: "When did you start taking chemistry class as a scumbag?" ”

The author laughed lightly and did not speak.

Looking at the colorless liquid sealed in the energy ball, Wang Chen whispered softly: "Although perchloric acid is one of the strongest acids on the earth, this little thing is a little insignificant in the fairy world. ”

As long as the monk is on the golden pill, basically everyone can release the aura, and the good control can condense into a protective shield of aura on the surface of the body, which can resist all harmful substances.

Even magic acid, which can corrode alkane candles, is helpless if it can't come into contact with the human body.

Wang Chen looked at the colorless strong acid in the energy ball, his eyes flickered, and a fist-sized beige hair ball appeared in his hand, and then he threw the hair ball into the strong acid.

This hair ball fell into the super corrosive perchloric acid, as if there was no problem, and the strong acid flooded the hair ball, and there was no change.

Wang Chen looked at these situations and his eyes were calm: "Sure enough, the corrosiveness is still too weak, and even Jiu'er's hair can't be corroded." ”

He threw it in, and this hair ball was Xiao Jiu'er's hair, which fell off when he mutated into a ten-life abyss cat before.

"In that case, let's strengthen the corrosiveness by the way. Wang Chen held the energy ball in both hands, and a white light emerged from his palm, and the white light entered the energy ball, and then the hair ball turned into a little bit of energy in it, submerged in the strong acid, and disappeared.

Wang Chen looked at the situation in front of him, and a faint smile appeared on his face.

"Calculating the time, Jiu'er and they will be back in almost an hour, and now is a good opportunity to build an iron-making furnace. Wang Chen looked at the sun that had already set in the west, it was about evening, the sky was already dark, and there was still a trace of burning clouds left by the setting sun on the horizon.

Next, he put perchloric acid in a storage ring and went in search of quartz sand.

The oxide of silicon is chemically stable and generally does not react with metal, and it is the items of this property that he wants to use to make iron-making furnaces.

In the water, Xiao Jiu'er and Shen Lihe are digging pyrite in full swing, and Deng Xiaoxing's excavation efficiency is relatively low, so he is responsible for transporting it.

I have to say that Deng Xiaoxing, the overlord of the Devonian Period, is still quite smart.

After following Xiao Jiu'er, his IQ gradually improved, and he actually went to attack a merchant ship at sea that had just finished unloading its cargo and was about to return to the sea, and used this ship as a container to load the excavated pyrite.

When the merchants on the boat saw such a strange-looking big fish loaded with a thick exoskeleton, they were immediately frightened half to death and jumped into the water to escape.

But the water is Deng Xiaoxing's home field, his bite force is extremely strong, and all the people in the boat were eaten by Deng Xiaoxing, and they were buried in the belly of the fish.

In this era, the shield fish has become extinct, and the only surviving shield fish is Deng Xiaoxing, and it is naturally impossible for them to know the Deng fish.

"This ship is quite large, it is full. Xiaoxing hurry up and transport it. Shen Lihe put a piece of pyrite into the boat and Deng Xiaoxing brought it to the shore.

The ship's load was almost ten tons, and Deng Xiaoxing's strength was so strong that he could completely drive the ship, so he latched on to the deck with his mouth and brought it to the surface.

It was already evening, and there were no fishing boat hunters around, otherwise they would not be frightened when they saw Deng Xiaoxing's body, and they would even think that he was some kind of ancient demon beast, and they joined forces to kill him.

Well, Deng Xiaoxing is indeed an ancient creature, and after evolving into a demon beast, his strength is more than one and a half stars stronger than that of ordinary demon beasts.

Deng Xiaoxing swam to the surface, poured out all the pyrite in the boat, and then took the empty boat to dive back into the water.

The volume of this boat was already the size of Shen Lihe, but after smelting it, it was estimated that it was only as long as three fingers and as thick as one ring finger of Xiao Jiu'er in human form.
