Seeing that Lao Jun was so excited, Huang Tongzi also became energetic, "Master, I'll show you how to do it below." When the chemistry teacher at the university of literacy was teaching gases, the apprentices had the best knowledge of the decomposition reactions. The god of thought also specially reminded me to pay attention to safety when using this oxygen. ”

"After a long time, you can get oxygen out for me!" Lao Jun sat down on the chair next to him. Seeing that the apprentice said so mysteriously, he was also faintly looking forward to it. With his understanding of Huang Tongzi over the years, even a lie has a basis.

"Master, please see, this is the chemical formula of oxygen extraction. In order to show the new knowledge more vividly and vividly, Huang Tongzi wrote a few chemical elements and formulas in bamboo slips.

Lao Jun took a closer look, what kind of mess this was. Can't you make it clear?

"Master, don't worry! there are many substances that can't be found here, we can only use immortal magic to retrieve things in the air!" Huang Tongzi put down the bamboo slip, "This oxygen is actually not very easy to extract, and things like our Heavenly Realm potassium permanganate can't be found at all." Thanks to the fact that we are immortals, our mana is transcendent, and we can avoid a lot of processes. The most important aspect is water electrolysis and deoxygenation. ”

"Will it work?"

"The molecular formula of water is H2O, that is, it is composed of two hydrogen atoms and one oxygen atom, so that the water molecules cannot maintain their molecular form, and then reduce them to hydrogen molecules and oxygen molecules. Two hydrogen atoms make up the hydrogen molecule is hydrogen, and two oxygen atoms make up the oxygen molecule is oxygen, so the hydrogen produced by electrolysis is twice as much as oxygen. This is the principle of water point solution. Huang Tongzi said.

Lao Jun was stunned for a while, "Is this electricity the electricity in the wind, rain, thunder and lightning? There are also Qing Atom and Yang Yuanzi are the ancestors of my Taoism, so you have to be presumptuous!"

Belch...... , Huang Tongzi went around for a long time, Lao Jun's knowledge seemed to be back to the original point, and the old guy should also go to the University of Illiteracy to take classes.

Seeing that Huang Tongzi looked helpless and ready to continue to explain, Lao Jun waved his sleeves, "Forget it, you just say that the old man can do things directly!

"Hehe, good!" Huang Tongzi smiled and said, "Master, look at the fish pond outside the alchemy room, you gently led a heavenly thunder down from nine heavens and injected it directly into the fish pond. Then you carve out a separate space where the hydrogen and oxygen come out and collect the oxygen and hydrogen. ”

After finishing speaking, Lao Jun believably followed Huang Tongzi's method and began to operate. Laojun's mana covers the sky, and it is said that it is not a problem to lead one heavenly thunder, even if it leads ten heavenly thunders. With a wave of Lao Jun's finger, there was a sudden sound in the sky, and a thunderbolt rushed into the pond. Lao Jun immediately activated his other hand again, separating two vacuum spaces between the water and the air to collect gas.

Two air masses appeared in the sky above the pond, which could not be seen or touched, but their presence could be sensed. At this time, Huang Tongzi also began to exert his strength, transporting a cold air to compress the air mass vigorously, making it liquid. Further compression and further compression.

After a few moments, the oxygen-filled space gradually turned ice blue, and the fish in the pond had turned into dried fish floating on the pond. Lao Jun glanced at Huang Tongzi incomprehensibly, "Didn't you mean gas?

"Master, this is the liquid form of oxygen, enough is enough, stabilize this space, let go of the thunder. Keep the oxygen in a vacuum, or the thing will evaporate. Huang Tongzi said cautiously, not daring to be sloppy.

With a whoosh, the thunder flew back.

"Okay!" Lao Jun did exactly what Huang Tongzi said. Trying to keep the oxygen liquid on the pond and sucking it into the alchemy room, while the larger hydrogen gas was suspended above the fish pond.

After getting the gas to the alchemy room. Lao Jun tore open the space, and a layer of white mist rose on the pale blue liquid in an instant, and all of it floated away. "What's going on?

At this time, Huang Tongzi came in with a bunch of dried fish from outside the pond, and chewed happily in his mouth, "Master, this is the gaseous form of oxygen, did you see it? I forgot to tell you that the liquid oxygen volatilizes too quickly." Let's do the experiment next time. ”

"Little bastard, you said it earlier, let's lead another heavenly thunder for the teacher. After Lao Jun finished speaking, he waved his hand to trigger the heavenly thunder again, "Apprentice, as a teacher, I smelled this white mist just now, and it smells more comfortable than the aura of Penglai Immortal Island." You said that if you drink this light blue liquid as tea, wouldn't it feel very sour?"

Huang Tongzi was speechless for a moment, and continued to gnaw on his dried fish in his mouth, liquid oxygen is a fuel boost, you drink it as tea, you can figure it out, "The oxygen in the pond is about to be squeezed dry, let's go to the East China Sea next time to extract it." ”

As he spoke, Lao Jun's body jumped, and he flew into the air of the alchemy room, wanting to intercept these white mists, but he couldn't contain them, and sniffed with his nose during the period, as if he wanted to smell what oxygen smelled like, "Colorless and odorless, good thing." ”

"Master, oxygen fuels combustion, it can't burn itself, but this hydrogen is a kind of fuel, listen to Brother Sansi's introduction, now this fuel is very widely used in the mortal world, why don't we give it a try?"

Looking at the remaining hydrogen on the pond, Lao Junna knew what it was, and when he came into contact with the magic of oxygen just now, he seemed to believe in Huang Tongzi even more. With a wave of his hand, the hydrogen gas mass outside was sucked in through the air, "What you said is true? If it is a great fuel, we can save the samadhi true fire in our alchemy." After speaking, Lao Jun was eager to try. Samadhi fire is not easy to control, and this operation consumes a lot of itself, so why not do it if the fuel can replace it.

"Then try it" Huang Tongzi scratched his hair, paused, and suddenly remembered a certain knowledge point in the book, "Master, don't worry"

Before he finished speaking, Taishang Laojun threw his big hand, and it was compressed into a basketball-sized hydrogen gas mass and sent it into the gossip furnace, "What's the problem?"

The next moment.

The rumbling alchemy room was razed to the ground, and a small mushroom cloud exploded in the lonely sky, and all the Samadhi true fire in the Bagua furnace at first erupted out of the Bagua furnace, causing the surrounding building materials to burn, and the fire became bigger and bigger. And the gossip furnace became red all over, making people unapproachable. Originally, a few golden pills in the furnace also exploded in an instant, turning into white gold-like powder.

"This!" Taishang Laojun's face was full of ash, his white robe had been burned to tatters, and he spit out a puff of black smoke, this hydrogen gas is too fierce, this level is not comparable to the Samadhi True Fire at all, "My Jindan! Jindan, which has been refined for a hundred years!

There was a cry of regret from the Doushi Palace, and he desperately reached out to pick up the gold dust. And the yellow boy on the side has been blown unconscious, the lower half of his body is buried in the building, and his face is covered by a dried fish.

If Lin Sansi saw this scene and couldn't laugh and leaned back and turned back, he dared to use hydrogen for alchemy after a passing score in the middle school chemistry exam, it can only be said that this classmate is very brave and dares to dedicate himself for science......
