To be honest, just when he found out that phlogiston said that it was correct in this world, Merlin almost shattered his three views, so that he would have to pass a large amount of san check on the spot.

Fortunately, he stabilized his mood in time, and after a little calm and thinking for a while, his mood stabilized.

"It's not that science is not good, it's just that my own thinking about science is skewed."

Merlin examined himself, and his method of assuming that the science of the previous life would work in this new world without even conducting basic experimental arguments was itself contrary to the norms of seeking truth from science.

"Then the next step is to do some experiments to demonstrate."

He took a deep breath and thought to himself.

Since people in this world also need to breathe, and there are plants in this world, then oxygen should also exist.

However, this does not rule out the possibility that this world is more strange, and the creatures here breathe some other gas instead of oxygen.

In short, in the end, everything has to be proved by experiments.

Merlin's consciousness continued to dive into the sea of consciousness, and he looked through the book of memories about chemistry that he had extracted before, looking for a way to prepare oxygen.

"Hydrogen peroxide hydrolysis, potassium permanganate pyrolysis, potassium chlorate pyrolysis ......"

He silently closed the book again, and looked up at the sky without words and tears.

"Rub, what are these things, in my previous life, these chemical raw materials could be bought casually on the street, but where should I find them now?"

These problems that did not need to be considered in the classroom in the previous life have become problems in this other world where there is nothing.

However, Merlin finally found two ways to prepare oxygen that did not require too complicated principles.

"Is it the method of electrolysis of water or industrial oxygen production?"

Merlin pondered the feasibility of both approaches.

..............

On the other hand, because Merlin interrupted the healing spell that was being released, the magic backlash after the spell failed made Cynthia a little uncomfortable.

Of course, she actually suppressed the backlash very quickly, but she still looked pale and was about to vomit blood, and she was looking forward to being able to sell a wave of misery in front of her younger brother, so as to bear her sister's efforts, and then deceive a wave of favorability or something.

It's just that when she saw Merlin contemplating, she opened her mouth, but she still didn't choose to disturb him.

"Alice, come over and give my sister a beating on the back, my sister's spell is so uncomfortable, this brother with a conscience is not reliable at all."

The witch who couldn't get her brother's comfort was a little bored, so she began to tease the little Lori who was playing soy sauce on the side.

And hearing Cynthia's words, Alice refused in her heart, she could sense the good and evil of others, she felt that this strange sister was not well-intentioned and was lying, but looking at Cynthia's pale expression, the kind-hearted little girl still softened, she stepped forward and carefully massaged Cynthia.

Because when her mother was still there, Alice often massaged her mother, so the technique was quite good, and the comfortable Cynthia's eyes lit up and she felt that she had picked up a treasure.

It's a pity that before she could enjoy it twice, Cynthia saw her lovely brother suddenly raise his head suddenly, and then look at her with burning eyes.

"Sister, you know how to do thunder and lightning sorcery."

Cynthia was taken aback by Merlin's reaction, and thought that she had revealed the fact that she had tricked little Lori into giving herself a massage, until she heard Merlin's words, she was relieved.

"Well, a little, but not very proficient,"

The witch continued to enjoy Lori's massage, and replied a little lazily.

"Oh, comfortable, Alice, push a little harder."

Merlin: "........"

He looked at Cynthia, who was squinting comfortably and slumping on the sofa, was Alice's massage technique so superb? Why don't I try it next time?

Phew, is now the time to think about this kind of thing?

Merlin shook her head and looked at Cynthia with a frown.

"Sister, how much will yours have?"

After all, this world is a steam-powered world, and there is no electricity, if he wants to electrolyze water, he can only rely on the power of magic, so he naturally has to ask a little more clearly.

"Not much, barely able to use the Thunder Hell Curse."

Cynthia heard Merlin's seriousness, and she hurriedly sat upright.

Merlin: "......"

After silently passing the occult in his heart, and then coming to the conclusion that the so-called Thunder Hell Curse was a powerful spell that could flatten a small city, he felt that Cynthia's forced pretense was not mellow enough, and it was a bit stiff.

"Is there any sorcery that releases electricity slowly and steadily for long periods of time?"

Although Cynthia had a look of "I'm not very good, do I worship my sister a little", Merlin selectively ignored her expectations, and he continued to ask.

He just wanted to electrolyze some water, and he didn't want to fight, so naturally he didn't need a high-lethal spell like the Thunder Hell Curse.

"Is there such a spell? It doesn't seem to be. ”

Cynthia frowned, reminisced, and spread her hands.

Most of the spells of witchcraft go for lethality, and the witchcraft of the thunder and lightning system is even more extreme in terms of instantaneous explosive power, and the witchcraft that slowly and smoothly releases electricity like the one Merlin asked for seems to be meaningless, and naturally no one has pioneered it.

"Sure enough?"

Merlin was a little disappointed, he just didn't find a similar spell in the occult knowledge of the original owner, so he wanted to ask Cynthia if he would know, but now he didn't even remember Cynthia, a sage, and sure enough, such a spell didn't exist.

"Brother, do you need it very much, then give me some time, I'll make one for you."

Seeing her brother's disappointed expression, Cynthia suddenly felt a little unhappy, her image of an omnipotent sister was stained, this is not good. As a sage, it is not difficult to create such simple witchcraft, and it can even be done casually.

But after all, this is the first time she has created witchcraft for her brother, so naturally she can't be so casual, even if Cynthia spent two seconds thinking about it, and she had a simple magic spell in her heart, but she still decided to spend at least a day to streamline, modify and improve, and test the safety of the spell, so that she can rest assured that she can hand it over to her brother.

Merlin didn't know what Cynthia was thinking, he just heard that there was no such spell, so he gave up the idea of electrolyzing water to produce oxygen, so there was only one last way left.

The high-pressure oxygen method commonly used in the industry.

In the previous life, such an oxygen production process had to be realized by expensive machines, and it was not something that ordinary people could afford to play at all, but isn't there such a useful thing as magic in this world?

"Since you don't have that kind of spell, forget it, then ask my sister to cast a spell according to this process, and we'll do an experiment now."

Merlin took out a pen and paper and wrote down the experimental procedures for industrial oxygen production, and marked a large list of spells on each step, and said to Cynthia.

He didn't bother to ask Cynthia if he would have these spells this time, anyway, the answer he got was nothing more than "a little understanding, it's not worth mentioning" or something, he didn't want to give this ghost woman another chance to pretend to be forced.

However, then again, a sage-level wizard is such a treasure, and it is so easy to use.

And Cynthia glanced at the paper Merlin handed over, and at first she didn't take it too seriously, but it soon became serious.

"Interesting idea, worth a try, really worthy of my brother. It's just amazing. ”

She didn't even care about the massage of the little Lori, and stood up directly excitedly, and her eyes were occupied by the curiosity that belonged to the wizard again.

"However, this room is a little too small to be used, so let's go outside."
