"What's that?"

As Merlin expected, Albert and Cynthia were dazed, completely unaware of what he was talking about.

"Is there such a word, this is another word created by yourself, brother, how can I understand these others."

Cynthia even complained about Merlin sensibly.

However, her words also left Merlin a little speechless.

This is the world of the Western background, so the common language of this world is also a kind of alphabet language similar to English, but it is plausible, and the name of a certain item is often an independent word, but Merlin looked for the original owner's memory, and it seems that there is indeed no word corresponding to oxygen, and the oxygen he just blurted out seems to be a new word that he subconsciously recombined.

Anyway, he still has 70 years of linguistic knowledge, and it is not difficult for him to put together a new word, and he is done subconsciously.

"Uh, I'm sorry, it was my mistake."

He had no choice but to apologize for the mistake first, and then asked the old headmaster and Cynthia rhetorically.

"What do you think is what makes the flame?"

Because the memory of the "Flame Sacred Book" in his mind was still being shielded, Merlin had to play a little cautious, trying to obtain some information about the interpretation of the principle of fire by people in this world through this rhetorical tone that teachers often use.

"Naturally, it's phlogiston."

Perhaps because of the thirst for the unknown knowledge that Merlin possessed, the old headmaster and Cynthia did not suspect much, they naturally took the bait, and Cynthia blurted out the answer.

"Phlogiston fills the heavens and the earth, flowing in the thunder and lightning. It is contained on earth, in heaven, in the sea, on land, in animals, plants, minerals, and in the hearts of men. The atmosphere contains phlogiston, which causes lightning in the air and causes turbulence in the atmosphere; Organisms containing phlogiston are full of vitality; Inanimate matter contains phlogiston and burns. Phlogiston not only has various mechanical properties, but also, like the soul, is itself a motive, the "power of fire". The object loses phlogiston and becomes dead ashes, the ashes gain phlogiston, and the object is resurrected. ”

The old headmaster then replied, his answer in more detail, which was also the original text in the Flame Sacred Codex.

Merlin was stunned when he heard such an answer.

"Phlogiston?"

He was a little stunned in his heart, he also had such a doctrine in his previous life, but this doctrine had been overturned a long time ago.

At that moment, Merlin smiled slightly, feeling that his opportunity to pretend to be forced had come, and he might be able to use scientific knowledge to slap the people of the other world in the face like those traverser predecessors today.

The smile on his face gradually brightened, but just as he opened his mouth to say "I don't think this is good", the sound of something breaking sounded in his head.

Merlin frowned slightly, he realized that it was the end of the punishment for the failure of the previous skill, and the chains that had sealed his memories of the Flame Sacred Book automatically shattered, turning into countless points of light and disappearing.

"It's such a coincidence, but I don't seem to need this wrong knowledge anymore."

He thought a little haughtily.

However, he thought about it for a while, but changed his mind, after all, because the phlogiston theory in his previous life had been overthrown a long time ago, so Merlin had only seen a little description of the phlogiston doctrine in junior high school textbooks, and he didn't know the specific content of the phlogiston theory.

So, with this thought in mind, Merlin swallowed the words in his mouth, and then quickly absorbed the memory.

There seemed to be a flash of memory in his blue eyes, it was obviously a moment, but it was as if a long time had passed, and with a tremor in his body, he came back to his senses.

It's just that after absorbing this memory, Merlin's expression became a little stiff.

"Rub, it's impossible, it's not scientific at all."

His heart was full of groans, because from the original owner's research memory, he was shocked to find that the phlogiston theory in this world was really correct.

Because there really is an element called phlogiston in this world.

In Merlin's world in the previous life, the so-called phlogiston was just a fictional element created by scientists, but in this world, the so-called phlogiston is real.

Of course, this does not mean that phlogiston can be seen with the naked eye alone, in fact, the magical element phlogiston can only be observed after blessing some special witchcraft or church magic.

And the Church's fire magic, the wizards' witchcraft of summoning flames out of thin air, is also realized by using magic to manipulate this phlogiston.

Therefore, those flame magic and fire witchcraft are naturally proof that phlogiston is correct.

If you are wrong to say that phlogiston is wrong, then there is no way to explain why these magic spells work properly.

"Rub, is it to talk about science in the world of magic?"

After confirming the memory of the original owner many times, Merlin's face became more and more stiff.

It's a shame that he still wants to use science to slap the faces of these people in another world and shake their three views, but now the retribution is coming so quickly, it seems that he was slapped in the face, and now his three views are shattered.

Merlin used to be superstitious about science, but now that superstition has been broken.

"Brother, what's wrong with you, why is your face so ugly, what's uncomfortable?"

Just as Merlin was still thinking about how this would end today, he felt a warm touch on his forehead.

When he came back to his senses, he saw Cynthia's worried face.

Originally, Cynthia was still looking forward to her brother's new knowledge, she stared wide-eyed and waited for her brother's class, but all she saw was Merlin's gradually ugly face, which scared the witch sister and couldn't even care about her thirst for knowledge, and hurriedly stepped forward and touched her brother's forehead, wanting to confirm whether it was her brother's body temperature and see if she was sick.

After all, because the demon king's heart does not match the human body, Merlin is indeed a little weak and sickly in addition to the obvious stunted development of this body, if it weren't for Cynthia, what she is best at as a half-elf is the magic of nature and life, Merlin really may not be able to grow so big, and she will die early.

"I'm fine...."

Merlin just wanted to explain, but was stopped by a stern look from his sister.

"Shut up, don't talk, sit down first, take a deep breath...."

Cynthia helped Merlin to sit down in her chair, and then started to prepare for a forbidden spell-level healing spell first, the kind that can bring back a person with only one breath left to full blood.

"I'm fine."

Merlin was a little crying and laughing, but not to mention Cynthia, after finding out that his face was wrong, the maid chief Vialis and the little girl Alice, who had been wearing soy sauce, also looked worried, and the old headmaster on the side was even more frightened to the point of heart attack, for fear that he, the last prince of the empire, would fall ill in his office, so what kind of face would he have to go to the emperors of the empire after his death.

This situation made Merlin himself wonder if he was really sick, and he involuntarily adjusted his breathing.....

emmmm ... Wait, breathe? Oh, isn't that still breathing? You still need oxygen to breathe.

Realizing this, Merlin immediately jumped up from his chair, and his movement frightened Cynthia, who was preparing a spell, almost backfired.

"I feel like I can salvage my pathetic science a little bit more."
