On the left side of Wall Street, in front of an ordinary alley, a delicate-looking boy passed by with a piece of black sesame bread, and suddenly the bread in his hand accidentally fell to the ground, he was taken aback, and hurriedly bent down to pick it up, but the bread was stained with dust, and he couldn't pick it up for a while, and he didn't pick it up, and he hesitated in front of squatting in front of the bread.

Pedestrians passing by on the street hurried to work, just glancing at them without paying much attention.

The boy lowered his head, as if he was distressed by the bread, but no one saw his nose sniff slightly.

The boy was none other than Dudian, and his attention was all focused on his sense of smell at the moment, and he inhaled gently and briefly, so that the smell could flood to the olfactory cells at the top of his nose, sharpening his senses.

There are all kinds of smells on the street, but tracking the smell is like a physical instinct, and it can be mastered without learning, Dudian focused his senses on the smell emanating from the hidden secret room in the alley, and through the various smells wafting in, a faint outline of the secret room suddenly appeared in his mind.

"Sulfur, yellow phosphorus...... Someone? Three people? One of the scents has a faint scent and is supposed to be a girl. Du Di was surprised, he didn't expect that there were people in this secret room at this moment, could it be that these alchemist apprentices were experimenting here every day?

Du Dian thought for a moment, and shifted his sense of smell to the residential house on the street above the secret room, and immediately smelled that it was filled with a faint smell of old gray, which was uninhabited and seemed to be empty for a long time.

"Beneath this empty house is the Alchemy Chamber...... The owner of the empty house is either long dead, or the owner of this alchemical chamber. Dudian thought to himself, he picked up the bread, patted the dust on it, and walked straight down the street, although by the smell he didn't find anyone at the high end of the buildings on either side of the street, there should be no one to keep watch.

Still, out of the prudence, do the full set of plays.

When he left the street, he came to a neighboring street, found a small tailor's shop, and immediately entered it.

He was greeted by a tailor's apprentice boy, who politely said to Dudian, "Guest, what do you need?" ”

Du Dian swept through the few finished clothes hanging in the store, and did not find the style he needed, and immediately said: "Help me make a set of black spacious robes, and an ordinary mask." ”

"Masks?" The apprentice tailor boy looked at him suspiciously, but didn't say anything, and said, "When do you want it?" ”

"When will it be done?" Dudian asked.

"Tonight."

"Okay, I'll get it this time tomorrow."

"No problem, what do you need, we have flax fiber here, satin ......"

"Just sturdy and ordinary fabric." Dudian asked, "How much deposit?" ”

The tailor's apprentice boy pondered for a moment and said, "If you want to be strong, the thick linen fiber is the best, and the two kinds are seven copper coins in total, and the deposit is half, and you will be charged three coins." ”

Du Dian immediately took out a three-copper coin and gave it to him, and said, "The robe should be a little bigger." ”

"Okay." The tailor's apprentice boy smiled and agreed, took out a ruler and measured the proportions of Du Di'an's body, then wrote a note to Du Di'an, and said, "Just come and get it tomorrow." ”

Dudian put away the note, left the tailor's shop, and muttered, "The next thing is the tattoo." ”

In order to infiltrate that stronghold, you must prove that you are an alchemist, and the most credible way to do so is to show your alchemical tattoo.

It's just that this era is far from mastering lasers, and once the tattoo is on the body, it is difficult to wash it off, and every time he comes back from hunting outside the wall, he will be checked on his body to prevent the virus from being brought into the wall, and he can't hide the tattoo at all.

He pondered for a moment, then finally decided to take the plunge.

……

……

An ink raw material factory in the eastern suburbs, like most factories, is located in a remote location, close to the radiation zone.

When Du Dian came here, he showed his guard medal when he was stopped by the doorman, and said, "I'm here to do business, and by the way, I will routinely check your production environment." ”

The two guards were a little stunned, and looked at them again and again to confirm that they were not mistaken, and one of them immediately glanced at the other, and then said to Du Dian: "Wait a minute, I will help you report immediately." ”

Dudian nodded, and stood in the doorway waiting.

After a while, the previous doorman trotted out with a short and fat middle-aged man, the middle-aged man saw Du Dian from a distance, and was stunned for a moment, as if he didn't expect such a young guard to look like a mature child, but he still immediately smiled and said politely: "Hello, why didn't you say it in advance when you came to check, haven't we always been under the control of Lord Crowe here?" ”

Du Dian waved his hand and said, "I just stopped by to have a look, mainly to do some business with you, do you have gallic ink here?" ”

When the middle-aged man heard this, he breathed a sigh of relief and wondered: "Gallic ink? This amount is very small, it has been discontinued, and now everyone uses carbon ink. ”

"That's good." Du Dian nodded and said, "Bring me a bottle of gallic ink raw materials." ”

"Uh......" The middle-aged man was choked suddenly, looked him up and down, and said, "Just a bottle?" ”

Du Dian coughed lightly, and was also a little embarrassed, after all, this is a factory and not a store, but it is difficult to sell gallic ink raw materials in the store, so he can only come here.

"How much?" Dudian asked the price directly, not giving him a chance to refuse.

The middle-aged man was speechless in his heart, but he still maintained a polite attitude and said, "Talk to me about any money, I'll give it to you." ”

Seeing this, Du Dian was not polite, and said, "I am short of time, so I want it now." ”

"No problem." The middle-aged man glanced at him and said, "Do you want this, no...... What else? ”

Du Dian smiled and said, "Just by the way." ”

The middle-aged man breathed a sigh of relief, knowing that he had a false alarm, and said with a smile: "Okay, I'll let someone get it for you." With that, he turned and left. Moments later, a slender young man brought Dudian a bottle of pitch-black ink.

Dudian can smell the ink inside without opening the cap, it is gallic ink, this ink was used in the early days of the wall, and later people learned to use coal to make carbon ink, this expensive ink is expensive, and gradually fewer and fewer people buy it.

Dudian left with the ink, went to the store and picked up a bottle of men's perfume, took it home, and locked it in his small room.

The smell of gallic ink is much lighter than that of carbon ink, and carbon ink is often used by people, and the smell is more familiar, which is why Du Dian took the trouble to buy gallic ink.

"It's a pity that there is no activated charcoal here, otherwise the smell inside can be completely eliminated." Dudian said secretly, he poured out the ink part in a small bowl, then poured some of the lighter perfume he had selected into it, neutralized the smell, smelled it, felt that the smell did not become weird, and then breathed a sigh of relief, and then stripped off his shirt, revealing a healthy wheat-complexed body.

Du Dian looked down at the demon mark on his chest, and said secretly: "I don't know if those alchemist apprentices recognize this demon mark, no matter what, it's better to hide it." "Immediately dip the ink on the quill, and draw along the blood-red magic mark on his chest, the cold ink fell on the magic mark, smearing this vessel-like magic mark black.

"This dagger scar should also be covered up so as not to attract attention." Dudian drew the ink along the dagger's scar, which was vertical, but horizontal, and when he was done, he found that the two strokes were crossed together, which happened to be a black cross.
