The root of the word ether comes from the ancient Greek, which originally means the upper layer of the sky, supplying the air that the gods in the sky breathe, and the first to put forward the concept of ether in the history of scientific development was the famous ancient Greek scientist, philosopher, and probably an alchemist Aristotle, who defined the ether as the stream of consciousness that makes up space, The first most basic substance created by the spirit world when it created the material phenomenal realm, that is, in the so-called four-element creation theory of alchemy, the primordial matter of the four basic elements of earth, water, wind and fire was differentiated and derived.

Although this explanation has a lot of fantasy, mystery and even superstition, it is not difficult for us to see that the substance of ether is the cornerstone of the definition of alchemy, and all the theoretical development and scientific research progress of alchemy are based on the actual existence of this mysterious substance......

But...... Otherwise, how could alchemy be ridiculed by the modern scientific system as a pseudoscience full of copper stench and unrealistic fantasies, and how could alchemists be considered crazy fools with brains smoked by sulfur vapor?

With these questions, I asked Mitch and Carl and the others, and of course, the words were more tactful, at least they didn't let these two foreigners hear the meaning of "I'm kidding me!".

"Yes, for centuries alchemy was nothing more than an entertaining topic popular at aristocratic banquets to set the mood, or a shoddy trick used in remote villages to deceive ignorant villagers," said the sentimental Mickey Mouse somewhat disappointed about the history of suffering at his own institute:" Although since the ancient Greek era, there have been countless predecessors who have devoted themselves to the study of alchemy, but it is unceremonious to say that the slightest progress has not been made for ten centuries, and the reason is that although alchemists have been able to achieve some seemingly magical material transformations in the eyes of laymen through basic chemical reactions, it took thousands of years to find that it exists in the theory of alchemy, and at the same time constructed the original substance on which the alchemy four-element transformation and all its derivatives are based on the refining theory, that is, the ether. ”

"But this stagnation was finally broken in the fourteenth century!" Karl happily took over: "The great alchemist and founder of the Alchemist Guild, Nikolai Freman, finally extracted a mysterious substance that he named the Philosopher's Stone in a fortuitous research accident, and with the power of the Philosopher's Stone, Freman succeeded in turning lead and mercury into gold!"

I scratched my head: "This story...... It sounds familiar. ”

Karl coughed and explained in a slightly embarrassed way: "Nicolas Freman is French, and his name is naturally French, but you may be more familiar with the English pronunciation of his name, Nicol Lemay......"

"Oh~~~!I know!" I couldn't wait to interrupt Mickey and Carl's singing: "He also knows a principal surnamed Deng, who is always domineering!"

"Those are all stories that need to be apocryphal," Carl also seemed to feel that it was a bit unreasonable for his god-like predecessor founder to only let outsiders find a sense of existence from children's books, and hurriedly brushed it off: "But Nicol Lemay found that the philosopher's stone is real, and the philosopher's stone is the ether!"

"It is rumored that after Lemay's death, the philosopher's stone disappeared, and in fact, the ether was handed over to the Alchemist Association that was already on the right track for secret preservation and research," Mitchell continued: "But whether Lemay, the Alchemist Association, or the current European Research Institute, they have tried all methods to successfully replicate the experimental process of discovering and extracting the ether, so although theoretically the aether fills all the space of the cosmic void, the philosopher's stone made by Lemay is still the only aether that can be used by the European Research Institute!"

"In fact, since the fourteenth century, all our energy has been invested in the ether, in addition to reproducing the process of Lemay making the philosopher's stone, more about using the ether to realize many ideas that alchemy originally only existed in theory, and so far, all the scientific research projects of the European Institute are basically based on the alchemy with the ether as the core. "Now you understand why the Aether is so important to us," Carr said, "because without the Aether, everything in the Institute would be nothing but rhetoric and fantasies, and the results that countless of us have spent years or even generations will be in vain...... So, we have to save the ether!"

I nodded understandingly, I have been in the institute for several years, and I can better understand the thoughts of scientific research madmen like them, they may not be familiar with the world or may be withdrawn and arrogant, but they are a group of people who have gone far on the road of dreams that most people have abandoned, so far away that when this road collapses, they would rather give their dreams and stick to the funeral than retreat half a step......

"So what should we do?" This is the first time that Xie Erdong has taken the initiative to take responsibility, and he is also a freak, and this grandson naturally resonates more with his European counterparts......

Unexpectedly, Mitch and Carl had a hard time with this question, and the two looked at each other before Carl was pushed out and said: " In fact, we don't know how to protect the aether, because the aether itself is an efficient catalyst that can be converted between the energy body and the material body, which can not only promote the alchemy reaction by consuming its own energy, but also supplement its own consumption by means of heat energy radiation, etc., according to this, we built the Omega warehouse, but in fact, this warehouse is an energy circulator, so that the ether can maintain its energy state through special energy pipelines throughout the castle, flowing and circulating between various research laboratories to maintain the normal operation of all alchemy equipment, and at the same time, the ether in the energy state is very active, and if it comes into direct contact, it will be assimilated into basic elements in an instant。 ”

"In other words, if Chen Xiaoshan's turtle son rushes up directly to grab something, he will be killed in an instant?" I asked with a glimmer of hope, but everyone responded with silence, so I thought about it a little and found that I had a whim: ether is the lifeblood of the European Research Institute, and it is naturally kept strictly secret from outsiders, even me, Black Dog, and Xie Erdong heard for the first time today, how did Chen Xiaoshan, who has been locked up underground for 70 years, know such a secret news? It must have been his chicken thief father who told him when his father and son hadn't turned their faces! With the old guy's urine, he must have quietly planned how to steal people's lifeblood out for research, and maybe his cheap son was listening to it when he was planning......

"But, since he's going to snatch the key to the warehouse, we'll be able to block him by rushing to the handle door first!" said Xie Erdong as if he were afraid of being blocked by us.

But this is the only thing we can do at the moment, so I had to take a deep breath to calm down: "So now, I only have one problem left, there are no deformed dogs with three heads guarding the door of your warehouse......, right? )
