In a hall of glorious lamp walls, John fell to his knees with his head pressed against the ground. The pain in his right arm, combined with the fear in his heart, made John tremble.

Around him, a dozen large men stood, each of whom looked powerful, with swords and axes in their hands, glaring at John.

Two meters away from John, a bald man of about forty years old was reclining on the sofa, squinting slightly, one hand supporting his head, as if asleep.

"Master Edward, you must call the shots for me, I was just retrieving the items that belonged to us for the master, but that kid actually came forward to intercept it, and ...... He also made such a ruthless hand. Master, that woman is so good-looking, I've only seen her once in the past two months, and if she runs away like this, won't we spend all the money?" said John, tremblingly.

"How can she be so good at running in the water? If you can run, the monk can't run away from the temple, doesn't she still have an aunt? Edward said slowly.

"She, how can she be so fat?" John looked up, nervous in his heart, "Use her to do business, and the customers won't all run away?"

"Even you don't run, of course there are a lot of people who want to get to her. Aren't they all the same when you blow out the lamp? Don't use your little fancy intestines in front of me. Edward opened his eyes and glanced at John.

"Yes, yes, aren't I also thinking about the master? if I delay the uncle's business, it will be my fault. John felt that his back was soaked with sweat, and a cold sweat began to form on his forehead.

"Of course it's your fault. No one is in your hands, you dare to sell it to me, you are not small. Edward touched his bald head and said with a smile.

"No, no, no, how dare I fool Uncle Edward? I really don't know, I've talked about it here, who knows that girl bought herself. John looked up and said in a panic.

"I'm not old, you don't have to hide some things from me, I know that some things are farther and deeper than you. Sometimes soft knives kill people more powerfully, of course, your IQ may not be enough, and I don't force you to do this. You said the man was wearing a mask?" asked Edward.

"Yes, yes, I don't know where the wild boy came here to play tricks, the master gave me a few people, and I went to yin him. ”

"You idiot, he dares to play with you so fearlessly, he must have his own background, you go over so directly, aren't you in the right hands? Edward rubbed his forehead, why didn't any of his subordinates know how to use their brains? It seems that in the future, you must have a degree to recruit people, otherwise you will have to be angry to death.

"The lord means to let them go like this today? I am bullied, even if I am bullied, isn't the lord's money spent in vain?" said John, gritting his teeth.

"I have always been the only one who eats other people's, who dares to eat me? You go and tell the fat woman to spit out ten silver coins, I will only wait until tomorrow, after tomorrow, you should know the consequences." As for those two people, especially the young man, I will arrange it myself. With a wave of his hand, Edward walked over to a large man.

Edward whispered a few words to him, and the big man nodded, and walked out of the room.

"I can understand the idea that you want to get elemental silver, but it's not the right way. I don't know where you got the knowledge, I think you want to replace inactive metal with reactive metal from liquid. With that, Aaron focused on Ruda's face and noticed his expression.

A layer of redness appeared on Ruda's face, his eyes became hot, and his hands kept rubbing, but his brows furrowed slightly: "That's right, that's what it looks like." Isn't the method wrong? Replacing inactive metal with reactive metal shouldn't be a big problem? That's what the book says. ”

"There's a problem, there's a big problem. Have you considered the possible consequences of using this method?" Aaron asked rhetorically.

"What consequences—what consequences?" said Ruda, confused.

"Your iron rod will replace metals that are not silver, such as copper, which is this layer of red solid attached to the surface of this iron rod. Aaron sighed, the man had only scratched the surface.

Ruda slapped his head hard and said regretfully: "How did I forget this knowledge." ”

"There's more to your experiment than that. In fact, the test solution is the most critical part of this experiment, and its importance can be said to account for 70 to 80 percent. But if I'm not mistaken, the liquid in your test tube is sewage from the sewer, right?"

Ruda nodded: "That's right, how do you know?"

If I can't smell such stinky water, I can only say that there is something wrong with my nose. Aaron thought to himself, but didn't say it, and simply asked, "Are you sure how much silver is in this water?"

Ruda listened to Aaron's words, and his face became nervous: "Yes, there were a lot of them last time. This time it shouldn't be much worse. ”

"Maybe it was different the last time you got the liquid. Sewage is inherently waste water, and its composition is changing all the time, so it is taboo to experiment with a fixed vision. Aaron said nonsense.

These words were made up purely to show his identity, but they sounded like truth to Ruda.

Luda held his head and slowly squatted down, and after four or five minutes, he raised his head again and cast: "Is there no room for remedy?"

"Nope. ”

The composition of wastewater is the most complex, and there are many factors to consider to complete such an experiment, otherwise the treatment of wastewater would not always be a big problem. After coming to this world, Aaron didn't want to deal with these things anymore, and came here this time purely to survive. Moreover, Aaron felt that this experiment was nothing to do, and the typical gains outweighed the losses. Not only does it take a long time, but the benefits are also pitiful.

Aaron's words hit Ruda hard, and it was a long time before Ruda raised his head, and the loss on his face was still not hidden at all.

Seeing Ruda like this, Aaron felt a little guilty, and he didn't know what impact his words would have on Ruda.

Ruda stood up, and after a moment of silence, he said, "Maybe you're right, but I'm not going to give up." I'm going to have to replace the silver in a more efficient way. ”

Aaron is not optimistic about Ruda's research prospects, if he uses the electrolysis cell, it may be faster, but where can he find electricity in this world? However, Aaron did not say these words, this time is really not suitable to attack Ruda.

"The question you asked me, I can tell you right now, I learned these things from a book. Ruda said.

"Which book, can I read it?"

"Wait a minute, I'll look for it. With that, Ruda turned around and lowered himself and began to rummage through a box against the wall. After a while, Ruda stood up and held a blue book in his hand, which was very worn, not only the cover was blurry, but even the sides of the book were rolled up.

"This is the ......" Aaron took the book and looked at the title, "The Basics of Alchemy?"

Aaron guessed by the name that this was a book about the basics of alchemy, and that it might contain the kind of mysterious potion he was looking forward to. Aaron thought for a moment Atoth, that guy didn't look like a person who was very advanced in alchemy, so he might have made the mysterious liquid in an easy way.

Aaron opened the book with great anticipation, but after seeing the contents, Aaron was dumbfounded, he had not only seen this book, but also was extremely familiar with it, because this book also had another name called "Junior High School Chemistry".

Of course, this book cannot be completely consistent with "Junior High School Chemistry", and many things have been changed, but the main thing has not changed.

Who is so cheating, take this book and publish it, aren't you afraid that XX Publishing House will sue him for infringement?

Aaron angrily turned the book to the title page, he wanted to see who the second brazen man he had seen in this world was.

Ivan Escuri?Why is this man's name so familiar?' Aaron frowned, desperately trying to figure out if he'd seen it somewhere.

Isn't Razor called Razor Escuri? Aaron suddenly remembered that he had seen this name in the book "Age of Empires", and Ivan Escuri was the founding emperor of this country, the Ravel Empire.

"Thank you very much, Mr. Ruda, I found the answer I was looking for. Aaron handed Ruda the Basics of Alchemy, then turned back to Frelia and said, "Let's go back now, I remember that I still have some things to do." ”

Frelia nodded. She didn't know what Aaron wanted to do, but she could see that Aaron was in a good mood now, which also showed that she could also help Aaron.

Aaron hurried out of the dilapidated room, and Frelia followed. Ruda looked at a gold coin on the table, swallowed a mouthful of spit, and when he came to his senses, the two of them had already left the room.

After getting the satisfactory results, Aaron's mind became active. Aaron didn't know why the man named Ivan knew so much about chemistry, but since he was able to write "The Basics of Alchemy", he would definitely write other books on alchemy.

The most important thing for Aaron now is to hurry back to the library of the Duke's Palace and see if he can find a book on alchemy.

All of Aaron's mind was on alchemy, and Felia barely managed to keep up with Aaron by almost running. At this moment, a dark shadow appeared not far from the two of them, and after making sure that Aaron and Felia had not noticed him, quietly behind them.
