The energy ball that Wang Chen threw in at the beginning was filled with liquid hydrogen, a by-product of oxygen production during the electrolysis of water, which was flammable and reducible.

Wang Chen used the reducibility of hydrogen to replace pyrite.

Originally, iron disulfide, which is difficult to separate, would not react so much with hydrogen, but the formation depicted by Wang Chen on the iron-making furnace increased the efficiency of the iron-making furnace.

High temperature, high pressure, coupled with the influence of Wang Chen and Shen Lihe's own realm breath, make it so easy to make iron, the use of pyrite in ordinary factories is used to make sulfuric acid, after all, it is too difficult to separate the sulfur ions and iron ions in it.

The hydrogen atom gives its own electrons, and the sulfur ions "love at first sight" for the hydrogen atom, so they naturally rely on it, and the two are combined in a ratio of 2:1 to form a colorless and toxic hydrogen sulfide gas.

"Hydrogen sulfide is toxic and can cause very much damage to the respiratory system, so don't go down until you take precautions, or your lungs will be damaged. Wang Chen earnestly advised.

"What about Jiu'er, her respiratory tract is very fragile, wouldn't it be bad to smell this gas. Shen Lihe watched as the area below gradually turned into a poisonous gas area, and his pretty face turned green.

She found that in the places where these hydrogen sulfide were shrouded, the surrounding creatures died instantly, and the few plants and trees around them withered in an instant, and it was obvious that this gas was very toxic.

"It's okay, I told Jiu'er before she left to hold her breath when she came back. "How could Wang Chen put his girl in danger, he had already told Xiao Jiu'er not to come back so quickly.

"Sister, you hold your breath, let's go down now. We can't smell hydrogen sulfide when the concentration is high, because it has the effect of paralyzing the olfactory nerves. Wang Chen reduced his body's metabolic speed to the minimum, his breath converged to the extreme, and he tried not to breathe.

Shen Lihe did as Wang Chen did and went down to the ground, while Deng Xiaoxing stayed in the air, after all, he couldn't do anything if he went down.

This white translucent iron-making furnace has become completely opaque at this time, and it is impossible to see the situation inside, and the formation patterns on the back of the furnace are flashing white light little by little.

Wang Chen opened the iron-making furnace, and a scorching gas gushed out like a volcanic eruption, Wang Chen felt that his eyes were a little uncomfortable, and Shen Lihe was constantly shedding tears.

"Damn, forgot to protect your eyes. Wang Chen temporarily covered his eyeballs with an energy protective film, and then he touched Shen Lihe's eyeballs and wrapped her eyeballs.

"Hmm. Shen Lihe wanted to say thank you to Wang Chen, but her cherry mouth was covered by Wang Chen, and Wang Chen's voice sounded in her head.

"Sister, don't speak, these gases are acidic and toxic gases, don't inhale them. Wang Chen operated on the iron-making furnace and took out a mold from the storage ring.

This mold is also made of silica, and it is very huge enough to fit one of Shen Lihe's feet in his main state.

Wang Chen opened the lid at the bottom of the iron-making furnace, and the crimson molten iron flowed out of it and into the mold.

After doing this, he and Shen Lihe once again loaded a batch of pyrite ore into the iron-making furnace, and then refined.

New ore entered, the iron-making furnace worked again, and Wang Chen did not stay in place, but flew into the air with Shen Lihe.

"Wow, this refining is a bit troublesome, and you have to be careful of the poisonous gas, my eyes hurt so much. Shen Lihe's beautiful big eyes were still crying, and now she was rubbing her eyes uncomfortably.

Wang Chen saw that Shen Lihe's dark blue eyes were a little purple, which was a sign of bloodshot eyes.

"Sister, if your eyes hurt too much, then don't go down, just wait here, I'll do it alone. Wang Chen took out a little soda ash, which was reacted by caustic soda when he was refining perchloric acid before.

All alkalis contain hydroxide ions, so alkalis can react with carbon dioxide to form carbonates, and Wang Chen used this principle to make those caustic soda into soda ash.

His hand dipped a little soda ash and gently wiped a trace of particles on Shen Lihe's eyeballs to neutralize the acid in his eyes.

"Heh, what kind of dragon do you think your sister is?" Shen Lihe's eyes returned to their original state, and there was a hint of annoyance on her pretty face, "Let me hide behind you and enjoy it, am I that kind of person." ”

"Okay, okay, you can follow me if you want. Wang Chen smiled helplessly, he knew Shen Lihe's temper, although this thunder dragon looked playful, her personality was very strong, and she was a little similar to Xiao Jiu'er.

Let her have the ability to do nothing and eat ready-made? Sorry, she can't!

Hydrogen sulfide covers not only land, but also sea, hydrogen sulfide is easily soluble in water, acidic in water, although acidic and corrosive is not as strong as sulfuric acid, but its toxicity is a fatal threat.

Microorganisms in the sea began to die in large numbers, and fish living in shallow waters also turned their bellies white, and their gills showed an abnormal purple red, which was obviously a sign of poisoning.

Hydrogen sulfide is not usually produced naturally, and sometimes the gas erupted from volcanoes is hydrogen sulfide, which is a toxic gas that usually occurs under high temperature and high pressure.

"What will happen to this hydrogen sulfide? You can't just let it be like this all the time. At that time, it will cause large-scale pollution, and if the atmosphere is destroyed, solar radiation and acid rain are possible. Shen Lihe looked at the hydrogen sulfide poison gas area below with an increasing concentration, and frowned.

She has no intention of destroying the environment.

"Well, it's good to treat it with lime water then, acid and alkali are the two extremes, and you can use this property to dispose of these poisonous gases very well. "Wang Chen also knew that once these hydrogen sulfides spread out, it would definitely have a great impact on the earth, and besides, this place is still a cultivation civilization, so he doesn't know anything about the treatment measures for this kind of thing.

"How to do it?" Shen Lihe knew that lime water was lime milk made from quicklime.

Lime milk is slightly soluble in water, and these lime milk dissolved in water is lime water.

"In this way, Deng Xiaoxing and I will go to the deep sea to dig stones, there is no way out of this vicinity for the time being, you can control the scope of the poison gas area here. Wang Chen took Deng Xiaoxing and flew to the deep water in the distance, which was not yet covered by hydrogen sulfide.

The sea breeze in the night, with a faint fishy smell, permeated the nasal cavity.

Shen Lihe's cute little nose moved, and his dark blue eyes flickered: "How do you feel weird." ”

She did a thorough job of protective measures this time, repeating the actions of the first ironmaking over and over again, but Shen Lihe did not feel bored, looking at the pure iron that gradually accumulated and became more and more in the mold, cooled and solidified, with a full sense of accomplishment in her heart.

As a weapon expert, Shen Lihe, the creation of weapons is one of the sources that makes her happy, she did not cut off her seven emotions and six desires like other cultivators, she is a monk with feelings.

At the same time, she released dragon energy, enclosing an area to prevent the hydrogen sulfide gas from diffusing out.

In the deep sea, Deng Xiaoxing conjured up his body and was swimming happily in the sea.

There were also many demon beasts in the deep water area, but they didn't dare to approach when they saw Deng Xiaoxing's strange appearance, coupled with a faint coercion on his body.

After all, the shield fish has long been extinct, and it is also the ancestor of most fish, such as sharks and coelacanths, which evolved after the shield fish took off its exoskeleton.

Because Deng Xiaoxing is a Deng's fish and belongs to the category of shield fish, his bloodline is older than the bloodline of these sea beasts, so he will have a coercion over these aquatic demon beasts.

Wang Chen's whole body was wrapped in a faint gray energy, isolating the water, he found a reef at the bottom of the sea, and mined it with Deng Xiaoxing.

"Big brother, what are you digging this stone for?" Deng Xiaoxing couldn't help but ask as he used the thick exoskeleton on his head to smash the reef.

"Maybe you don't know the principle yet, but in short, I'm going to calcinate these stones into quicklime, and then add water to turn them into lime milk, which is a kind of alkali, which has many common names, generally called lime slurry, and sometimes calcium hydroxide. ”

Wang Chen didn't explain much, after all, Deng Xiaoxing didn't know anything about these things, if he wanted to learn, he could teach it slowly when the time came, but now he couldn't learn it in a short time.

Quicklime is a metal oxide, whereas hydrated lime is an alkali.

"Alright, let's go back. After digging for about an hour, Wang Chen dug up ten tons of reefs, and he put all these stones into his storage ring, ready to take them back for refining.

In just over an hour, Deng Xiaoxing captured the heart of a swordfish demon beast, and now these two guys are getting tired of being together.

Deng Xiaoxing's super defense and strong bite force made this sailfish happy.

"Wo Cha, little brother, you can. Deng Xiaoxing had a girlfriend so soon, Wang Chen couldn't help but feel a little embarrassed, this speed is really fast enough.

From meeting to such intimacy, it only took more than an hour, and those who didn't know thought they had known each other for a long time.

"Little sister, I'll go first, I can only make a pair of morning mandarin ducks with you, and if I don't go back, my eldest brother will spank me." Hearing Wang Chen greet him, Deng Xiaoxing could only reluctantly say goodbye to his swordfish sister.

The swordfish also humanized its eyes in place to say goodbye.

The short time that Deng Xiaoxing and the sailfish were together gave birth to a strange idea in Wang Chen's heart.

An ancient creature shield fish, with a modern-day sailfish...... What kind of baby will be born?

.........

After returning to the position just now, Shen Lihe was refining the last batch of ore materials, and the refining was soon completed, Wang Chen threw all the rocks brought back into the furnace.

The chemical properties of calcium are very active, and in this high-temperature iron-making furnace, it quickly turns all into quicklime.

Wang Chen added water to the quicklime, and when the lime reacted, a large amount of white foam emerged, and the temperature rose rapidly.

He then took the lime slurry to a high place and sprinkled it underneath, and the lime slurry and hydrogen sulfide were neutralized and turned into calcium sulfide and water.
