Chapter 93: : New research

On the second day, Dudian went to the hidden alchemy room again. When he came, the snake and the ‘rat’ that he had tracked before were also there. The boy of the code-named mouse should have listened to the snake and talked about Dudian. When he saw Dudian, he asked nervously: "Hound dog, you, you follow me over, so, you...had seen me?"
Du Di thought that there was no way to deceive and nodded: "I have seen it, I will keep it secret."
The mouse was frustrated and said: "It is exposed again."
The viper did not say good-spiritedly: "Who asked you to engrave the tattoo on your wrist, I see you, you will be purified by the light sooner or later, and don't sell it when we are."
"I won't sell you." The mouse frowned and said: "My family has been engaged to me. I want to withdraw from the alchemy now. Anyway, at my level, it is difficult to achieve something. I can mix up with a comet badge."
The snake shrugged: "If you want to quit, remember to strip the tattoo."
"I just worried about pain, I have been hesitating." The mouse was helpless.
Du Di'an was speechless. He looked at the nightingale's alchemy room and asked, "Is she not coming today?"
"This time has not come, it is estimated that it will not come." The snake snakes.
Dudian said: "Can I borrow her alchemy symbol book to see?"
"This is casual, but it is best not to touch her other alchemy materials."
Du Dian nodded. When they went to the experiment, they picked up the alchemy symbol book of the nightingale and continued to silently recite it. Although he has super chips, the modern chemical system stored in it is much more advanced and perfect than the alchemy system of this era, but the ancients do not mean backwardness. There are still many advantages in this alchemy system that are worth learning. After all, this is chemistry. The ancestor of the embryo.
Du Di'an first revisited what he had left yesterday, and then continued the alchemy symbol behind him.
Another day passed.
Du Di'an was about two-thirds of his back. At dusk, he left the alchemy room with snakes and rats. This time, the viper was the first to leave. The mouse finally broke the tail and was responsible for filling the passage. Newcomers do not worry about them.
After Du Di'an came out, he saw the poisonous snake hiding again and wanted to peek at himself. He ignored him and went around the road in the direction of yesterday and returned home.
On the third day, Du Di'an continued to come to the alchemy room. Today, the nightingale is also there. He borrowed the alchemy books and continued to silently. Before leaving at night, he finally turned the whole book down and could already understand the experiments of the nightingale and others.
From the symbols portrayed on the alchemy platform, Du Di'an can roughly guess what experiments they are going to do. When he returns the book, he quickly glances at the night alchemy platform and immediately sees a sun symbol and two water droplet symbols, as well as the spoon symbol. I couldn’t help but be surprised. The ambition of this nightingale is quite big. I even studied gold directly. Do you want to directly create the stone of the sage?
The fourth day.
Du Di'an came to the alchemy den as usual. Today, the viper is not there. The nightingale and the mouse are busy. Occasionally, the mouse will run out to ask some questions about the nightingale. Here, her alchemy level is the highest.
"Don't watch today?" The nightingale saw that Du Dian did not borrow books from her, strangely.
Du Dian shook his head: "Don't look."
"No?" The night said: "What do you mean, have you been back?"

Yeah.
Du Dian nodded slightly and said,
I want to start learning to experiment.

The nightingale understood it and smiled. "It seems that you have had a lot of backs before. I said, how can you even experiment with the alchemy symbols? If you want to experiment, the materials must be purchased by yourself. Today I can borrow it first, provided that I have extra money, but you have to return it to me tomorrow."

Thank you!
Du Di'an thanked her heart. She looked up and swept the raw materials on her shelves. She immediately saw a few raw materials for making black powder. These raw materials are also commonly used in other alchemy experiments. Black powder is the old age. The earliest invention of the motherland has had a tremendous impact on the whole world. It originated from alchemy, and alchemy is actually equivalent to the alchemy of the East, which is earlier and more advanced than the West.
"This yellow phosphorus is my point." Du Di'an pointed to one of the bottles, black powder. He naturally does not intend to manufacture here, although in modern times, this is not a technology, it is a very old technology, but it is absolutely explosive in this era. Alchemy, and it really can "explode"...
The nightingale glanced at it and nodded. "Well, I have a lot of this."
Du Dian asked for some ingredients such as gum and red scales, and then cleaned the small warehouse. Then I suddenly found a problem... there is no alchemy!
He is a bit dumbfounded. This is not a black powder. It has a complete formula. It only needs to blend the raw materials. He intends to study the match. When he first detonated the black fire, he felt that the ignition was a problem. The fire igniting that is commonly used in the world is too inconvenient. It needs to be repeatedly slammed with fire steel to wipe out the spark and ignite the velvet. Time is terrible.
Du Dian found the nightingale again and curiously said: "Where is your Alchemy Desk?" No one can dare to sell this thing on the market.
The nightingale is arranging raw materials. When Du Di'an is found, he wakes up and realizes: "I forgot to tell you this, so let's go find a mouse and see if he has no time at night. If you have time, take you. Go to the underground market to buy one, but the price is a bit expensive, you better prepare more money, at least two silver coins."
"Underground market?" Du Di'an Wei Wei, suddenly thought that Rosyard's notes seem to have mentioned this place, the market of the Dark Holy See underground trading, there are strongholds in various places.
Immediately, Du Dian found the mouse and said things again.
The mouse didn't think much, and promised to take him in the evening.
Du Di'an had nothing to do, he said hello to the nightingale, left the alchemy den, and thought that three days had passed. Barton had no idea what they were doing, and immediately hired a carriage to the slums.
When he arrived at a dilapidated square that had been agreed in advance, Du Di'an soon found the secret number left by Barton and others, and a smile appeared on his face. He followed the slogan and found a remote shack near the slum. Refugee gathering place.
Just before Du Di'an came to the shack, he heard the surprise sound of Barton in a shack opposite the shack.
Du Di'an looked at it, but saw the low shack open, Barton and others came over, three days disappeared, and several people were a little more spiritual than before.
"We exposed the cipher, so we rented another one on the opposite side." Barton looked at Dudian's expression and explained it awkwardly.
Du Di'an groaned and smiled. "You think it's quite thoughtful." Although the possibility of revealing the secret is extremely low, Du Di'an is very happy to see such caution.
