"My doubt?" Ella looked up and down at the girl, "...are you?"

"The 'gray wolf' you just mentioned refers to the stony ore. The stony ore is believed to be related to lead. Pliny, a naturalist of the Seven Hills Empire, once recorded in his "Natural History" that stony ore is easily converted into lead; the stony ore is written as 'Spiessglanz' in the text of the Almani Federation, which means the luster of the weapon, so its name is 'affiliated with the warlike Ares'; the molten stony ore can dissolve the gold nuggets instantly, impurities float on the surface, and the gold will sink into the bottom of the white alloy, so the 'gray wolf' will swallow the 'king'; and when baking this white alloy, the gold will reappear, and the 'king' is redeemed and turned into pure gold."

The girl said to herself in front of Ella. Amy was confused when she heard it, while Ella was so shocked that she opened her mouth wide: "You are right. After trying many possible substances, I found that this 'gray wolf' refers to the stony mine. Are you a student in the school? I am about to enter the school. What does it mean if you say there is no answer I am looking for here?"

The girl cleared her throat and was about to answer, but a shout suddenly came from the corridor: "Everyone is coming out! That hateful Avicenna is coming to school again!"

As soon as the shouts fell, the whole building exploded. The sound of panic footsteps sounded from each room, the door of the alchemy laboratory was opened, and all kinds of strange smoke floated from each room to the corridor, making the corridor full of strange smell. The unkempt and dirty alchemists rushed out of the room and ran towards the gate. Someone turned around and saw the girl wrapped in white cloth, ran over and grabbed her, shouting: "What are you doing here? You are not a student of the school! Go and mop the floor!"

"Not a student?" Ella was stunned for a moment, and stopped the man and wanted to ask what was going on. But the man shouted anxiously at Ella, "There is no time, haven't you heard it? Avicenna is here! Let the boiler fire be put out and stop him at the gate!"

The whole building soon became empty, leaving only the dark smoke gathered on the roof.

"Avicenna?" Ella stood in the house and murmured to herself, "Is it that Avicenna? He is now in the Island Republic?"

Poor Amy experienced too many things that she could not understand in a few minutes, and her mind turned into a muddy: "Your Majesty, what kind of Avicenna do you know? Everyone is so panicked. Is that a monster that can spit fire? Oh no, I will spit fire too... I have never heard of such a thing. The guard should rest in the woods behind the building. Should I take them to the school gate to intercept it?"

"Avicenna is a personal name... When I was a child, my father was seriously ill, and all the doctors in the entire Seven Hills Empire were helpless. Finally, a young man named Avicenna came to cure him. He was only nineteen years old that year. Now that Avicenna should be a very famous miracle doctor, but I just don't know if Avicenna is the same person in their mouth... Forget it, this is an internal thing in the Alchemy University, let's not care about it."

Ella shook her head, then lifted her sleeves.

"What we have to do now is pass the entrance test! I have many questions that need the teacher from the Alchemy University to answer for me - Amy, isn't the fire yet?"

Just as Ella was concentrating on the entrance test, Lazi and his group who had just held an open-air lecture by the pool at the entrance of the school were confronting Avicenna. Lazi and his group were more than twenty, all wearing black robes and golden badges. In contrast, there were only three people in Avicenna. Avicenna had a square face, a big beard wrapped around his entire chin and cheeks. His head was wrapped in a white turban and a thick book in his hand, and he looked like a very intelligent scholar. The two people following Avicenna were short and fat, and the other was tall and thin, dressed like a businessman, and had a great status in the Island Republic.

Although Lazi and his group had an absolute advantage in number, and teachers and students kept coming from the school to support each other, they were obviously shorter than Avicenna in their momentum.

"Lazy, I'm calling you, lift your head up.Lazy, you are a member of the committee of this school and one of the most famous alchemists of this era. What do you mean by having such a low profile? Didn't you just talk here and talk endlessly?" Avicenna said sarcastically, "Come on, the students are here, tell them, what did you just say?"

"According to the latest discovery of Jabir's residual article, I successfully separated the four properties of cold, hot, dry and wet..."

"Oh, it is a great achievement to separate the properties that are more basic than the four elements. Your achievements have surpassed Jabir Ibn Hayan, surpassed Zosimos, and even surpassed Aristotle. After I go back, I report to the Governor of the Island Republic and ask him to give you the name Para Aristotle - just hope that this time you can successfully show your experiment in front of the Governor, and don't have any accidents like last time."

Avicenna said sarcastically.

"But, Lazi, this is just part of your lecture. What else did you say just now? Why hide your knowledge? Come and repeat it and tell them to the students and teachers behind you who long for knowledge. They will definitely be shocked by your intelligence!"

"Each metal is composed of four properties in precise mathematical proportions, just as you say in medicine to maintain health. Gold is a healthy metal, and the four properties are in a perfect proportion. Other metals are sick and need to be cured by adjusting the body fluids. Therefore, as long as gold is dissected through dissolution, volatilization, etc., analyze the correct proportions of the four properties in gold, and then use the elemental substances of the four properties I separate, the proportions of the four properties in the base metal can be correctly adjusted and turned into gold..."

Avicenna laughed: "Did you just hear it? He said 'Volatile Gold'! What kind of alchemy joke is this? As a doctor, I know that gold is the most perfect and stable metal. Who can volatile gold? Can you? Can you? Can you?"

Avicenna pointed his fingers one by one over the alchemists in front of him, and all the people he pointed at were pretending to be invisible and turned their heads away. Avicenna pointed everyone aside and finally returned to Lazi: "Lazi, they don't seem to be able to do it. But since you have proposed this plan, I think you must have already had a plan to evaporate the gold, right?"

Lazi gritted his teeth and whispered: "This kind of thing needs further research..."

"Oh! Further research! This is a perfect answer. However, the Governor was tired of hearing this answer."

Avicenna pointed at himself, and then at the two behind him.
