The linen bag this burly boy was carrying was small and bulging. He obviously hadn't strengthened his body like Du Di'an. 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 detected.
"At his age, he should only be an alchemy apprentice, but I don't know whether he uses it himself or helps his teacher buy alchemy raw materials." Du Di'an's eyes showed a bit of thought. At this time, the strong boy stopped a car at the intersection. The carriage, the carriage and the carriage leave.
Du Di'an's face changed slightly, and he quickly followed.
In this bustling and prosperous area, the speed of the carriage is not fast. Du Dian trotted behind him with a linen bag on his back. His strengthened body and daily training for three years made his endurance far surpass that of ordinary people, and he followed continuously. After seven or eight streets, Du Dian felt breathless. When he was about to hire a carriage to track, he suddenly saw the carriage in front of him stopped.
Du Di'an stopped quickly, and saw the sturdy boy jumped out of the carriage, turned around and paid the copper coins, and then entered the alley by the roadside.
Du Di'an 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, and it was blocked by a wall, and the burly boy disappeared in the alley. inside.
what the hell?
Du Di'an raised his eyebrows slightly. After all, he was a person who was influenced by science. Naturally, he would not believe that there would be the kind of magic in fairy tales in reality. He entered the alley and looked carefully on the ground.
This sealed alley, apparently few people enter, the dust is everywhere, and there are several buckets of garbage piled up at the entrance of the alley. Because of this, Du Di'an's sharp vision strengthened, and he immediately saw the traces of footprints in the dust on the ground, and this The traces continued to spread forward and stopped at a wall in the middle of the alley.
Du Di'an's eyes flashed, and he came to the wall to take a closer look. He couldn't help but startled. He saw that this was a wall. It was clearly a piece of fabric painted the same color as the wall.
"This kind of hidden trick is really an alchemy apprentice." Du Dian reached out and touched it, but saw that the back of the fabric was hard, and most of it was held by some stone, so it would not be dented and exposed by mice or wind.
Du Di'an secretly took note of this place, turned and exited the alley. Obviously, this is the stronghold of an alchemist. If it is reported to the Holy See of Light, he will be able to receive a lot of merits as a scavenger immediately. However, he has no interest in doing such a thing, on the contrary, he is going to infiltrate the small circle of this stronghold and understand the alchemists of this world.
The author's tale has been misappropriated; report any instances of this story on Amazon.
After all, what he knew about the alchemists came from Rothyard's handbooks. Although there were a lot of things recorded on them, many of them were only information mastered by senior alchemists, and there were few records of basic things.
However, if you want to join the circle of alchemists, you must become an alchemist.
The first step of the alchemist's proof is the black tattoo.
Du Dian has not thought about tattooing himself, nor is he ready to join the circle of alchemists so soon. After all, according to Rothyard's records, the circle of alchemists communicates in other identities. The purpose of this is, I was worried that if any of them were exposed, they would be arrested by the Knights of Light, tortured and confessed to others.
"After returning from outside the giant wall, I will officially consider this." Du Dian glanced at the alley, turned to the intersection, stopped the carriage, and headed to the slum. He learned a principle since he was a child, and doing a lot of things at the same time affects efficiency.
Soon, the carriage came to the boundary wall of the slum, Du Dian jumped off the carriage and returned to the long-lost slum. As soon as he approached, the strong smell in the air made him frown slightly, and there was a hint of helplessness in his heart. , can only endure this strange smell, follow the trail to a more remote place, and find a dilapidated small hotel to rent.
In the hotel room, Du Dian took out several raw materials in the linen bag. The first step was to extract the sulphur ore from the sulphur. He was going to use the most primitive extraction method to heat the sulphur ore with high temperature, dissolve it, and extract it. The sulfur solution in the upper layer is cooled, that is, sulfur, and then ground into sulfur powder with a stone wheel.
Du Dian and the hotel owner wanted a brazier. Although it was the rainy season at the moment, it was strange to have a brazier for heating, but under the copper coins given by Du Dian, the hotel owner agreed very happily. When he took out the dusty brazier in the warehouse, he returned it to him. a few pieces of coal.
After Du Di'an returned to the room, he locked the door with his backhand, lit the fire with the fire sickle given by the hotel owner, burned the coal, and then built the sulphur ore on it. After burning for a while, the fire was too weak, and Du Di'an simply bought one from the hotel owner. Big bags of coal.
The melting point of sulfur is not high, and it melted quickly. Du Dian took out the utensils purchased in advance and began to hold the sulfur solution.
The room was full of the strange smell of sulfur. Du Di'an was secretly glad that he was prepared and put on the mask. Due to the nuclear radiation, the mask did not seem to disappear along with the technological fault, but appeared in people's lives all the time.
It has to be said that different environments promote different development.
Du Dian thought that he would make a gas mask like Rothyard in the future. For alchemists, they often deal with various substances and inevitably ingest some toxic substances. The effect of masks is minimal, only used by alchemy apprentices. Just use it.
In the evening, Du Di'an finally got the ground sulfur powder and fire nitrate. As for the charcoal, he was going to go back and make it himself. 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 that were smudged with coal, and smiled bitterly, suddenly longing for his own alchemy room one day.
"I hope I can make a lot of money by going outside the giant wall this time!" Du Di'an wiped the ashes on his face, and his fighting spirit was high.
...
...
In the blink of an eye, seven days passed.
The night before the mission, after Du Di'an said goodbye to Jula and his wife, he sat in the black carriage sent by the Mellon consortium's scavenger headquarters, returned to the business district, and lived in the old ancient building as they watched. 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." Macon said excitedly: "Tomorrow I will be able to go outside the giant wall. I wanted to go and see it when I was young, but I was scared by the terrible stories they told. ."
"You'd better save it. 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 what Du Dian put on the bed, and said, "Dian, what is this that you brought?"
"Toys." Du Di'an said casually, and glanced at the black fire explosive tube he had made in the past seven days, thinking that it was impossible not to be taken with it when it was packaged like this.
