The fat woman's eyes widened in disbelief at what was happening in front of her. How could this man, who was like a sprout in front of her man, catch her man's attack?

"You...... Let go of ......" The man gritted his teeth and tried to pull his hand out of Aaron's hand, but tried several times, but it was unsuccessful. Sweat ran down the man's forehead like beans, but no matter how hard the man tried, he couldn't make Aaron move a bit.

Aaron smiled coldly, turned his wrist inward, and a scream of "oops" rang out, and the man knelt on the ground with a painful face, his right arm twisted in a strange way.

Aaron let go of his hand, and the man's arm fell limply to the ground.

Seeing this kind of man, Aaron was also startled. The fact that he had inflicted such serious damage on this man with a casual blow was far beyond Aaron's imagination. It seems that it is still a little useful to learn swordsmanship with Crayford, and he has not suffered so much in vain.

"John, what's wrong with you?" the fat woman screamed and ran to the man's side, the man was prostrate on the ground, his body trembling, and his low groaning voice was unbearable. The fat woman looked at John's arm, which hung limply and limply, clearly obsolete.

"You're so ruthless, how can you get rid of it?" the fat woman yelled at Aaron.

"If you don't get out, I'll scrap you two together. Aaron was in no mood to sympathize with them and shouted at them.

"You...... You'll win this time, but it's not over, and we'll get revenge. The fat woman gritted her teeth, picked up the man, and fled back into the darkness.

Aaron looked in the direction in which the two men had disappeared, and wondered why the antagonist always had this line, not wanting to kill them, but after hearing this, he suddenly felt the urge to kill them. However, if they were to be killed, Felia would probably be sad.

"I'm sorry, young master, for causing you trouble. Felia lowered her head, tugged at Aaron's clothes, and whispered.

"That's why you're reluctant to come back?" Aaron asked.

Frelia nodded. I am not afraid that the young master will know that he is a poor person, and he doesn't mind letting the young master see his down-and-out appearance. She just didn't want him to witness her embarrassment and her ugliness when she couldn't resist fate.

"You, wouldn't it be better to say such a thing directly in the future? Hide it, won't you still have to solve it in the end?" Aaron touched Felia's head with pity, "Okay, don't think about these unhappy things anymore, hurry up, take me to the neighbor you said." ”

Frelia nodded, and walked past Aaron.

The two men had traveled thirty or forty meters, and when they were about to turn the corner, Felia stopped.

"Here?" Aaron asked. It's also a squirrel cracked house, and there's nothing special about it compared to other buildings. The walls were made of broken and thin wooden planks, but they were too fragile to keep out some cold winds, and it was almost impossible to resist the forced entry of outsiders, as if the thin walls could be kicked open at once. However, although the walls do not look solid, they make the room so tightly that it is difficult to find a gap where you can see the scene inside the room.

Felia nodded, took two steps forward to the door, and knocked softly on the door.

"Who? There was a voice from inside, and the tone was very unhappy.

"Uncle Ruda, it's me, Felia, who has come to see you. Felia said obediently.

"Oh, Felia, aren't you leaving? Or are those guys lying to me? Don't worry, wait a minute, I'll open the door. ”

Having said that, Aaron and Frelia still waited for two or three minutes. When Aaron was bored, the narrow wooden door finally opened, and out of it came a thin old man, who looked about fifty or sixty years old, not very tall, wearing a peaked cap, and feeling like a university professor.

"It's really you, Felia, well, you're dressed up beautifully today. Hehe, by the way, we haven't seen each other in half a year, right?" asked Ruda.

"Why, it's only been two months. Felia smiled sweetly.

"yes? Oh, why do I feel like it's been half a year?" Ruda looked up and thought for a moment, "Maybe I'm mistaken? By the way, Felia, are you looking for me? Huh? Who is the person behind you? wearing a mask, not from the ghetto." ”

"Uncle, it's not convenient to talk here, can we go into the house first?" asked Freia.

"Into the house?" Ruda frowned, looked at Aaron behind Felia, and then pulled Felia over, looked at Aaron cautiously like a thief, and then whispered to Felia, "It's not that you don't know, these things of uncle can't be seen by others." ”

"Uncle, you can rest assured of him. He is no one else, he is someone who can be trusted. Felia whispered.

"Can you be trusted?" Ruda glanced at Freia suspiciously, "Why am I so scared?"

"No one else can believe me, but you can't trust me?" said Felia, patting her on the chest, "I can assure you that he's absolutely fine." ”

Ruda looked at Fei Lia and showed a look of embarrassment: "Oops...... Forget it, it's up to you this time, not next time. ”

"Thank you, uncle. Frelia turned around and made a successful gesture to Aaron.

Aaron was overjoyed, took two steps forward and came to Ruda, and just as he was about to open his mouth to speak, Ruda spoke in advance: "I told you, this time it was for the sake of Concubine Lia's face that I let you in, next time it won't work, do you know? ”

Aaron doesn't care what this next time, only if he can go in for the first time, there will definitely be a second and third time...... When the time comes, it's up to you to bargain.

Ruda's house is not big, it seems to be eight or nine square meters at most, Aaron has not been to other poor people's houses, but it should be about the same, and he can barely have a place to live.

Aaron followed Ruda and Frelia into the house, and immediately felt familiar. The room was filled with all kinds of instruments, such as test tubes, funnels, droppers, glasses, and some simple instruments, which were arranged in such a mess that the place that could only be used for sleeping was immediately dwarfed. Aaron wondered if the man named Rueda could actually rest here.

In the very center of the room was a small, shabby table, on which lay a simple rack of test tubes, on which was placed a test tube with half a test tube in it, and a metal rod inserted into it.

Although Aaron's academic performance was not good, he could still see at a glance that Ruda was replacing metal with chemical methods.

"Sir, what are you ......" Aaron said as he walked over to the table and pointed to the test tube.

"Don't move! Don't move! Ruda rudely interrupted Aaron.

I rub something that I can play with my eyes closed, and even say that I can't understand?

But Aaron now has a request for help, and he has to swallow his anger.

"What are you doing here, Mr. Ruda?" Aaron asked, pretending to be stupid.

Ruda glanced at Aaron and didn't answer Aaron.

Aaron has a bit of a headache, this guy doesn't seem to want to take care of himself, it seems that he really needs to show two brushes.

Aaron was also angry, and walked around the table, noticing a reddish-brown solid on top of the iron rod. Aaron guessed that this solid was elemental copper. But if it was just ordinary copper, Ruda would never be so nervous, which shows that there are other metals on the iron rod besides copper.

Thinking of this, Aaron put all his attention on the copper. Sure enough, after a few minutes of closer inspection, Aaron noticed that there was a tiny silver solid attached to the copper.

It turned out to be engaged in this thing. Aaron suddenly lost interest and snorted softly.

"What are you doing? Don't bother me. I let it in for the sake of Princess's face. Ruda heard Aaron's soft grunt and felt a little unhappy. He was already a little upset, and he became irritable. Felia also gently pulled Aaron's clothes on the side, for fear that Aaron would do something that would make Ruda angry.

"I know what you're doing, but I don't think you can make it. ”

"You know what?" said Ruda, impatiently.

"I don't understand anything, I just know that you want to make silver. However, it seems that the progress is not too good. Aaron said casually.

"Silver, how is that possible?" Princessia covered her mouth and let out a surprised sound, but seeing Ruda's eyes wide as if she had been poked in the sore spot, the girl did not take Aaron's words as a joke.

"What else do you know?" Ruda slapped the table, and the impatience on his face was swept away, replaced by eagerness.

"I don't know much. For example, it's hard to refine silver now, and it's hard to separate silver from copper. Aaron said.

"You know all of this, do you have a solution?" Ruda became enthusiastic.

Aaron fumbled in his pocket, then pulled out a gold coin and placed it on the table.

"What do you mean?" Ruda swallowed, staring at the gold coin.

"It's not interesting, I just don't think you're getting more than you can gain. It took so long and so much effort, and the rewards outweighed the losses. ”

"I'm not doing this for money! I want to know why!" Ruda slapped the table, and the test tube rack fell, and the green liquid flowed out of the test tube, and a foul smell quickly spread through the air.

"It's okay to tell you why, but you have to tell me where this knowledge of yours comes from. It was only at this time that Aaron said what he wanted.

Ruda turned his back and fell silent.

Aaron's eyes remained motionless as he thought about the possible consequences and whether he had prepared for them.

"Well, if you can tell me why, I can tell you this knowledge I learned from there. Ruda turned, the gloom on his face dissipating, and his eyes showed a thirst for knowledge.

Aaron let out a sigh of relief, seeing Ruda's instrument, Aaron knew that he could no longer expect to get the preparation of that mysterious potion from Ruda's here, but if he knew the source of Ruda's knowledge, then his goal could be regarded as accomplished.
