Banshee Castle, Craftsman District.

There are more than 30,000 people in the city, and more than half of the population is crowded in this area less than one-fifth of the urban area. When you ride on a horse and look around, you can see low houses, narrow streets, dark corners, and dodging faces.

The people living here are low-income civilians, most of whom make a living by working for the powerful. The thieves who need to hide their identities also like this. The sheriffs of Banshee Castle rarely come to patrol, and the residents inside rely on themselves for everything.

Zhou Qingfeng was "invited" from his home by Rom. He didn't want to stay in a hotel, so he simply looked for a place to stay in the craftsman area. The clown Adrian was very familiar with this kind of mixed place, and he easily chose an inconspicuous house for him.

"The house looks dilapidated, but it's quite spacious inside. You can clean up three rooms. Horses and mules can be kept in woodshed, without affecting life. The only flaw is that there is no independent well and you need to go to the street to buy water to drink."

Adrian hired someone to clean the house in advance, and Zhou Qingfeng just needed to lead a horse to live there. This should have been his safe house in Banshee Castle. He could come here to avoid it when he encountered trouble, but now it is equivalent to public use.

The wall is low, and you can see the new master and servant Zhou Qingfeng when you step on the foot of a few families next door. However, most of the people living here are honest. When they see guests with horses, they know that they are not able to afford it.

Seth was also used to living at the bottom. He patroled the inside and outside the house, then walked around the surrounding streets, and hired two servants, a man and a woman, to serve Zhou Qingfeng's daily life.

Zhou Qingfeng compensated Rom for a set of alchemy equipment and reached a cooperation agreement, and then ordered Adrian to go to the market to pay attention to information from all aspects. He decided to stay in Banshee Castle for half a month and experience the life here in depth.

Kelly also arrived at Banshee Castle, but the halfling was not sure what she was doing and did not show up. She asked her through the information network and she only said that Inesa had told her, "Don't live with Victor" so that a man who was not jealous of the food would attack in the middle of the night.

"Am I that kind of person?" Zhou Qingfeng was so angry that he was so angry that he was so angry that he had no choice but to deal with Kelly. After he moved in, he built a small laboratory bench in his room to continue his feasibility study of his "cheap advanced light source".

Uncle Zhou finally realized the reality and decided to start with the most basic alchemy method. He bought pottery that could withstand high temperatures to store lava stones from the abyss, and worked on his own to face the high temperature and high heat lava stones, which would immediately dissipate.

The lava stone is like a piece of red iron, with too high heat. Simply hang it out as a light source, the temperature in the house will rise quickly. But this way, the heat dissipation is too fast, and a piece of lava stone as big as a fist will become cold if it can't last for two or three hours.

"Sofia, is there any arcane rune that can slow down the energy release of lava stones?" Zhou Qingfeng asked his assistant.

"This requires searching the information in the "Gate of True Knowledge." Sofia replied: "Brother, your direct entry into the big library can increase my search speed, and all solutions can be simulated in the alchemy laboratory."

The five-pointed star necklace projected the "Gate of True Knowledge" in the bedroom, and Zhou Qingfeng walked into the large library. The longer he used this strange object, the more he became proficient in controlling it.

As the mental power spreads, more than a dozen alchemy monographs flew out from the bookshelf and floated in the air, automatically opening and reading. Without Zhou Qingfeng's direct vision, Sophia can quickly search the information in the book through the information network.

After reading one book, change it. Sophia read hundreds of advanced alchemy secrets that outsiders can hardly find in a few hours. This is a bit like brushing papers before doing research. Whenever she finds something, she will be picked out for projection.

With a lot of practical research in the past as the basis, Sofia selected hundreds of solutions to limit the emission of light and heat of lava stones. Zhou Qingfeng took these solutions to the alchemy laboratory next door for simulation.

Some plans were successful, but not efficient. Some plans failed and exploded directly. Some plans were effective, but had high requirements for materials and were too expensive. There was no promotional meaning for a night of struggle. Zhou Qingfeng did not choose a suitable plan.

After a dizzy and walking out of the "Gate of True Knowledge", Zhou Qingfeng felt that his brain power was consumed too much. Huge amount of knowledge came easily, but all simulations were actually carried out with the help of his brain. This seemed easy, but it was actually a headache.

"I am really not suitable for scientific research." Zhou Qingfeng felt very frustrated. He put away the elf and wanted to lie down. But as soon as his head was stuck on a pillow, Sophia reminded: "The person named Rom is shouting 'Holy Light' wildly."

"If there is no big deal, don't let him bother me. I want to sleep for a while." Zhou Qingfeng said lazily.

"Then I'll block his call." Sofia replied. Her existence was also based on Zhou Qingfeng's mental state. Zhou Qingfeng was tired, and she was also tired.

Within half an hour of blocking the call, there was a clanging knock outside Zhou Qingfeng's door. Fatty Rom's shouting and Seth's dissatisfaction scolding each other. He had to get up and open the door with sleepy eyes.

"What happened?" asked Zhou Qingfeng, who was red-eyed.

Rom danced excitedly outside the door and grinned, "I succeeded, I succeeded."

“What succeeded?”

"Physical potion. Lord Hugo, you are so awesome." Rom pushed Zhou Qingfeng into the room, closed the door, and said in a low voice: "The method you got from Succubus is completely correct, and I succeeded in one experiment."

A bottle of red potion was taken out from Rom's pocket and swayed in front of Zhou Qingfeng's eyes, "Look, look. This is what I have refined. This high-quality physical potion can be sold for a gold coin in one bottle, and it is absolutely popular.

Thank you so much, Lord Hugo, thank you so much. The knowledge you taught me came in handy. I will definitely join the wizard group of Banshee Castle this time, and they will never refuse me. Lord Little Firs will also appreciate me."

There is no harm without comparison!

Look at how people solve the problem overnight, and the refined potions can be bought at a high price. Uncle Zhou can't even get a "light". It's really bad, which seriously undermines his enthusiasm for scientific research.

"Rom, did you understand the alchemy information I gave you in one night?"

"It's very simple, only a dozen pages, quite easy to understand. I was very inspired after reading it. The knowledge from the demons is indeed extraordinary. It's really good to write, better than those big pages of thousands of pages.

True knowledge is worth tens of thousands of yuan, but it turns out to be so simple. I am so excited that I can't sleep at all, so I must come and express my gratitude to you."

Rom seriously praised Zhou Qingfeng for his generosity. But when Mr. Zhou heard this, he felt that every time Mao talked about learning, I felt that these people were calling me stupid openly and secretly?
