The next day, Dudian returned to the secret alchemy chamber, and when he arrived, the viper and the 'rat' he had tracked down were also there. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 The boy with the code name Rat must have heard the Viper talk about Dudian, and as soon as he saw Dudian, he asked nervously, "Hound dog, you, you followed me, so you ...... Have you seen me? ”

Du Di thought that there was no way to deceive him, and nodded: "I've seen it, I'll keep it a secret." ”

The mouse's face was full of frustration and said, "It's exposed again." ”

The poisonous snake said angrily: "Who asked you to engrave the tattoo on your wrist in the first place, I think, sooner or later you will be purified by the light, and then don't betray us." ”

"I won't betray you." The mouse said with a sad face: "My family has engaged me, and I want to quit alchemy now, anyway, at my level, it is difficult to achieve anything, at most I can mix up a meteorite badge." ”

The viper shrugged and said, "If you want to quit, remember to peel off the tattoo." ”

"I'm just afraid of pain, so I've been hesitating." The rat said helplessly.

Du Dian was a little speechless, looked at the nightingale's alchemy room, and asked, "Isn't she coming today?" ”

"I didn't come at this point in time, so I guess I won't come." The viper said casually.

Dudian said, "Can I borrow her alchemy symbol book to see?" ”

"It's casual, but it's best not to touch her other alchemy materials."

Dudian nodded, and when they were busy experimenting, he picked up the nightingale's alchemical symbol book and continued to memorize it silently. Although he has a superchip, and the modern chemical system stored in it is much more advanced and perfect than the alchemy system of this era, but ancient does not mean backward, and there are still many advantages worth learning in this alchemy system, after all, this is the prototype of chemistry.

Dudian first revisited the one he had memorized yesterday, and then continued to silently observe the alchemy symbol behind him.

Another day passed.

Du Dian carried about two-thirds of the back, and at dusk, he left the alchemy room one after another with the poisonous snake and the rat, this time it was still the poisonous snake that left first, and the rat was the last to cut off its tail and was responsible for filling in the passage, and this matter was handed over to a newcomer to do They were not at ease.

When Dudian came outside, he saw the poisonous snake hiding next to him again, trying to peep at him, but he ignored it, made a few circles in the direction of yesterday, and returned home.

On the third day, Dudian continued to come to the alchemy room, and today the nightingale was also there, he borrowed the alchemy book and continued to memorize it silently, and before leaving at night, he finally memorized the whole book, and he was already able to understand the experiments of the nightingale and others.

Just from the symbols carved on the alchemy table, Du Dian could roughly guess what experiment they were going to do, and when he returned the book, he quickly glanced at the nightingale's alchemy table, and immediately saw a sun symbol and two water drop symbols, as well as the spoon symbol, and couldn't help but be surprised in his heart, this nightingale's ambition is quite big, and he actually studied gold directly, did he want to directly make the Philosopher's Stone?

Day 4.

Dudian came to the alchemy den as usual, today the poisonous snake is not there, the nightingale and the rat are busy, occasionally the rat will run out to ask the nightingale some questions, here her alchemy level seems to be the highest one.

"Not watching it today?" The nightingale said strangely when she saw that Dudian had not borrowed a book from her.

Du Dian shook his head and said, "Don't look at it. ”

"Not really?" Nightingale was stunned and said, "What do you mean, you have already memorized it?" ”

"Hmm." Du Dian nodded slightly and said, "I want to start learning to do experiments." ”

Nightingale understood, and said with a smile: "It seems that you have memorized a lot before, I said, how can you do experiments without even memorizing the alchemy symbols, if you want to do experiments, you have to buy the materials yourself, I can lend you some today, provided that I have a surplus, but you have to return it to me tomorrow." ”

"Thank you!" Du Di thanked with peace of mind, looked up and scanned the raw materials on her shelf, and suddenly saw several raw materials for the manufacture of black powder, which are also commonly used in other alchemy experiments, black powder was the earliest invention of his motherland in the old era, which has had a huge impact on the whole world, and originated from alchemy, which is actually equivalent to the alchemy of the East, which is earlier and more advanced than the West.

"I'll ask for this yellow phosphorus." Du Dian pointed to one of the bottles, black powder he naturally did not plan to make here, although in modern terms, this is not a technology, it is a very ancient technology, but in this era, it is definitely explosive alchemy, and it can really "explode"......

The nightingale glanced at it, nodded and said, "Okay, I just happen to have more of this." ”

Du Dian asked for some raw materials such as gum and red scales, and then cleaned the small warehouse, when he suddenly found a problem...... There is no alchemy table!

He was a little dumbfounded, this is not to make black powder, there is already a complete recipe, and it only needs to be mixed with raw materials. He was going to study matches, and the last time he detonated the black fire, he felt that ignition was a problem, and the ignition of the fire sickle commonly used in this world was too inconvenient, and he needed to be repeatedly attacked with fire steel in order to spark and ignite the velvet, which was simply fatal at a critical time.

Du Dian found the nightingale again and asked curiously, "Where did your alchemy platform come from?" "No one in the market would dare to sell this thing.

The nightingale was preparing raw materials, and when he saw Du Dian looking for it, he was stunned for a moment, and then he came to his senses: "I forgot to tell you this, so let's go find a mouse, see if he is free at night, if he is free, take you to the underground market to buy one, but the price is a bit expensive, you had better prepare more money, at least more than two silver coins." ”

"Underground bazaar?" Dudian was slightly stunned, and suddenly remembered that Rothade's handbook also seemed to mention this place, which was a bazaar for the underground trading of the Dark See, and had strongholds in various places.

Immediately, Dudian found the mouse and told him what had happened.

The mouse didn't think much of it, and promised to take him over again in the evening.

With nothing to do for a while, Dudian said hello to the nightingale and left the alchemy den, thinking that three days had passed, and Barton did not know how their affairs were doing, so he immediately hired a carriage and went to the slums.

Arriving at a dilapidated square agreed in advance, Dudian quickly found the code left by Barton and the others, with a smile on his face, followed the code all the way, and soon found a small shack in the middle of nowhere, which was close to the refugee gathering place in the slum.

As soon as Dudian arrived in front of the shack, he was in a shack opposite the shack when he heard Barton's surprised voice.

Du Dian looked at it in amazement, but saw that the low shack was opened, and Barton and the others came over, and they didn't see each other for three days, and they were a little more energetic than before.

"We exposed the code, so we rented another one on the other side." Barton looked at Dudian's expression and explained in a smug manner.

Du Dian was stunned and said with a smile: "You guys are quite thoughtful. Although he knew that the possibility of the code being exposed was extremely low, Du Dian was still very happy to see them so cautious.
