The linen bag carried by this burly boy was small and bulging. He obviously had not strengthened his body like Du Dian, and it was very difficult to carry it on his shoulders.
Du Dian's vision is more than three times that of ordinary people, and he follows far behind without worrying about being noticed.
"At his age, he should only be an alchemy apprentice. I just don't know whether he will use it himself or help his teacher to buy alchemy raw materials." Du Dian's eyes showed a little thought. At this time, the strong boy stopped a car at the intersection. Carriage, take a carriage and leave.
Du Dian's face changed slightly, and he quickly followed.
In this lively and bustling area, the speed of the carriage is not fast. Du Dian trots behind with a linen bag on his back. His strengthened body and three years of day-to-day training have made his endurance far beyond ordinary people. After seven or eight streets, Du Dian felt out of breath. When he was about to hire a carriage to follow him, he suddenly saw the carriage in front of him stop.
Du Dian stopped quickly, and saw the burly boy jump out of the carriage, turned around and paid the copper coins, and then entered the alley by the side of the road.
Du Dian immediately walked over, pretending to be passing by, and turned his head to look into the alley. He couldn't help but be astonished. He saw that the alley was a dead end, sealed off by a wall, and the burly boy disappeared into the alley inside.
What the hell
Du Dian raised his eyebrows slightly. After all, he is a person who has been influenced by science. Naturally, he would not believe that there would be magic in fairy tales in reality. He entered the alley and looked carefully on the ground.
Obviously few people enter this sealed alley, dust is everywhere, and there are several barrels of garbage piled up at the entrance of the alley. Because of this, Du Dian's sharpened vision immediately saw the traces of trampled footprints in the dust on the ground, and this The traces spread forward and stopped at a wall in the middle of the alley.
Du Dian's eyes flashed, and he came to the wall and took a closer look. He couldn't help being startled, and saw that it was a wall. It was clearly a piece of cloth painted with the same color as the wall. If you don't look carefully, you can't tell it apart.
"This kind of hidden trick is indeed an alchemy apprentice." Du Dian reached out and touched it, but saw that the back of the fabric was hard, and it was probably blocked by some stone, so it would not be exposed by mice or wind.
Du Dian secretly remembered this place, turned around and exited the alley. Obviously, this is a stronghold of alchemists. If it is reported to the Holy See of Light, as a scavenger, he can immediately receive a lot of merit. However, he was not interested in doing such a thing. On the contrary, he was going to mix into the small circle of this stronghold and learn about the alchemists of this world.
After all, what he knew about alchemists came from Roseyard's notes. Although there were many things recorded in it, most of them were only mastered by advanced alchemists, and there were fewer records of basic things.
However, if you want to join the circle of alchemists, you must become an alchemist.
And the first step of alchemist proof is black tattoo.
Du Dian has not thought about tattooing himself for the time being, nor is he ready to join the circle of alchemists so soon. After all, according to Rothyard's records, the circle of alchemists communicates with other identities. The purpose of doing so is, I was worried that if anyone was exposed, he would be arrested by the Knight of Light and tortured to confess to others.
"After coming back from the giant wall, I will formally consider this point." Du Dian glanced at the alley, turned around to the intersection, stopped the carriage, and went to the slums. He learned a truth since he was a child, doing many things at the same time, which affects efficiency.
Soon, the carriage came to the boundary wall of the slum area. Du Dian jumped off the carriage and returned to the long-lost slum area. As soon as he approached, the strong smell in the air made him frown slightly, feeling a little helpless in his heart , I could only endure the strange smell, followed the path to a relatively remote place, and found a dilapidated small hotel to rent.
In the hotel room, Du Dian took out a few raw materials in the linen bag. The first step was to extract the sulfur ore from the sulfur. He was going to use the most primitive refining method, using high temperature to heat the sulfur ore, dissolve it, and take The sulfur solution in the upper layer is cooled to produce sulfur, which is then ground into sulfur powder with a stone wheel.
Du Dian asked the hotel owner to come to a brazier. Although it is the rainy season at this moment, it is a bit strange to ask for a brazier to keep warm, but with the copper coins given by Du Dian, the hotel owner still happily agreed to take out the dusty brazier in the warehouse. A few lumps of coal.
After Du Dian returned to the room, he locked the door behind his back, lit the fire with the fire sickle given by the hotel owner, set the coal on fire, and then built the sulfur mine on it. After burning for a while, the fire was too weak, so Du Dian simply bought one from the hotel owner. Big bag of coal.
The melting point of sulfur is not high, and it melts quickly. Du Dian took out the utensils he bought in advance and began to fill the sulfur solution.
The room was filled with a strange smell of sulfur. Du Dian was secretly glad that he was prepared and put on the mask. Due to the nuclear radiation, the mask did not seem to disappear with the technological fault, and it has always appeared in people's lives.
It has to be said that different environments promote different developments.
Du Dian thought it would be good to get a gas mask like Roseyard in the future. For alchemists, they often deal with various substances, and they will inevitably ingest some toxic substances. The role of the mask is minimal, and it is only used by alchemists. Just use it.
In the evening, Du Dian finally got the ground sulfur powder and fire nitrate. As for the charcoal, he planned to make it himself again. This thing is simple.
"I didn't expect that it would be so tiring to make the oldest black powder." Du Dian looked at his clothes stained by coal, smiled wryly, and suddenly yearned for a day when he could have his own alchemy room.
"I hope I can make a lot of money by going outside the giant wall this time!" Du Dian wiped the ashes from his face, and his fighting spirit was high.
…
…
In a blink of an eye, seven days passed.
On the night before the mission, after Du Dian said goodbye to the Juras and his wife, under their watchful eyes, he sat in the black carriage sent by the headquarters of the scavengers of the Mellon Consortium, returned to the business district, and lived in the previous ancient building. In the castle, Macon and others were brought along with him, as well as other scavengers who graduated together.
"I heard that we will leave early tomorrow morning." Macon said excitedly: "Tomorrow I will be able to go outside the giant wall. When I was young, I wanted to see it for a long time, but I was frightened by the scary stories they told. .”
"You'd better save yourself. Although the outside of the giant wall is not as scary as they say, it is definitely dangerous." Zach said.
Sham smiled slightly, looked at the things Du Dian put beside the bed, and said, "Dean, what did you bring?"
"Toys." Du Dian said casually, and glanced at the black fire explosive tube he had made in the past seven days, thinking that it would be impossible not to carry it with the package.
