Captain Kai was a pretty good guy. He was probably afraid that Su Lun would take a wrong path, so he explained everything in great detail.

However, Kai didn't know that the talent Su Lun awakened wasn't D-grade [Eagle Eye], but the S-grade dual talent; nor did he know that he wasn't trying to advance to an ordinary profession, but already had a golden job-change material with a very high compatibility, the [Rune Puppet], to become a rare class, the "Puppet Master."

So, those job-change suggestions that were suitable for ordinary people weren't suitable for Su Lun.

Indeed, as Kai said, choosing alchemical implants required a high degree of compatibility with one's profession and talent to achieve a combat power effect of 1+1>2.

Melee types would choose implants that enhanced the physical body, assassins would choose agility enhancements, and magic types would choose various implants that improved casting efficiency...

But Su Lun's professional path was already focused on both skill and agility growth, making implants widely applicable, but difficult to find with high compatibility.

As it stood, aside from the Silver-grade [Thousand Kill Wings] implant, which had a relatively high compatibility, the Black Iron implants he could access were somewhat of a "waste" of his own attributes.

But he thought, what if... there were something even more compatible?

Su Lun didn't dwell on this issue.

The matter of alchemical implant blueprints wasn't urgent yet, because that was something he would face after becoming a professional.

First, he had to make some preparations for his "job change."

Becoming a "Professional" not only required exclusive job-change materials, but also some items for arranging the conversion array. Such as magic crystals, stibium, mercury salts... and various powdered metal mediums like red copper and gold.

After a night of toil, the hustle and bustle of Grimm Street gradually subsided.

As the most lively nightlife district in the Southern District, the city's awakening dawn was its dusk.

It's worth mentioning that the Underground City had no sun or moon. The distinction between day and night was marked by the city's fog and lights.

At night, the fog would engulf the entire city, and the municipal office's light towers would be turned off to save energy. During the day, the fog would dissipate and the lights would illuminate the streets.

6:55 a.m.

The Cross Society gang members on Grimm Street were still in the embrace of pleasure, while Su Lun had already left.

Because the city's factories had a large number of steam boilers in operation, the smoke and dust produced by coal burning made the fog a faint gray, and the air was filled with a thick smell.

There were five minutes left before the city train departed, and there weren't many pedestrians on the street.

Su Lun changed into a large black trench coat, and a bowler hat covered most of his face as he squeezed into the waiting crowd. A slight breeze entered his collar, bringing a hint of coolness.

"Ding-ling-ling~"

Before long, after a crisp copper bell, a steam-powered tram "woo-woo" drove in.

Like taking the bus in his previous life, Su Lun squeezed on board.

Arriving at the station, he got off.

The Byrd District in the Northern District was the intersection of the four districts. The X-shaped intersection of the two main streets was also the boundary line of the three gangs' territories. This place didn't belong to the territory of the three major gangs, and the Northern District's Security Office couldn't reach it either, making it a "three-no's" zone with a complex web of forces.

And under that intersection, there was an inconspicuous alley leading to the underground—"Shadow Alley."

Underground, there was a professional black market named after this alley.

There were interconnected underground pipes that connected to the complex sewer system of Old Lingdun. Even if they were surrounded by a large force, the people inside could scatter and escape through the sewer network.

Therefore, because of the special geographical environment, this place gradually formed the largest underground black market in the Outer City.

.......

"Shadow Alley" was the favorite gathering place for Wastelanders and adventurers. They would bring their hunting harvests from outside the city to sell here: cursed materials, alchemical scrolls, ores, rare cursed objects... and many bizarre ancient alchemical products.

This was also the favorite extraordinary market for the Outer City professionals, because there were many goods that weren't commonly seen, or even unavailable, on the market.

Here, as long as you had money, the black market shopkeepers could always satisfy you.

Many illicit goods, such as stolen goods from thieves and spoils from murders, could be found in some inconspicuous shops in Shadow Alley.

Famous guns, swords, advanced potions, alchemical bullets, steam machinery, alchemical blueprints, and even military-modified prosthetics from the Inner City, high-end alchemical materials that only nobles could enjoy... and top-secret intelligence.

Everything was available here.

.......

Things that couldn't see the light of day were always hidden in dark corners.

There was a dim gas lamp every ten meters, and the light was dim.

Su Lun walked through a long underground passage, going down about one or two hundred meters, before reaching a huge underground crevice.

This "Shadow Alley" wasn't a flat street, but a three-dimensional building complex.

The old sewer pipes were neatly arranged on the rock walls, and the ends of the pipes were endless darkness leading to who-knows-where in the depths of the earth. People relied on the pipes to build small shops with steel skeletons. Like the "Hanging Temple" in Su Lun's previous life, they relied on various simple steel structure stairs and bridges for passage. Da Feng Novel.com

Su Lun stood at the entrance to the street, looking at the dark, endless abyss in front of him, a hint of contemplation flashed in his eyes.

Without lingering, he went straight to the shops.

His feet stepped on the steel plate road surface, making a clanging sound.

Perhaps because it was still early, Shadow Alley, which had just opened for business, didn't have many customers.

Su Lun looked over.

These shops were mostly only a few square meters in size. Some materials were hung at the door, announcing what the shop sold. Occasionally, a few would write a small sign with charcoal and hang it at the door: "Black Witch's Alchemical Materials Shop," "Starry Sky Bookstore," "Giant Machinery Shop"...

Interestingly, Su Lun actually saw his own "Missing Person Notice" on the street's bulletin board.

No, to be exact, it was the original owner's.

Although it wasn't a wanted order, the photo stated that providing clues would earn you 10,000 Lisol. This was already the bounty price for a B-class wanted criminal.

Very tempting.

This was a bulletin board for posting information on the purchase of materials. Half of it was filled with various purchase information, and the transaction address codes were also left behind.

Only people who frequented the black market knew what those codes meant.

On the other side was a page for information merchants to exchange information. Like a small advertising area in a newspaper, it was densely filled with various "Missing Person Notices," bounties, and transaction codes.

And Abelock, the A-class wanted criminal "Yin Scorpion" who died in the arena yesterday, was also at the forefront. However, his photo had already been marked with a red cross.

Su Lun only glanced at it and didn't look any further.

The wanted poster listed Fick Regardi, a brown-haired teenager. What did that have to do with him, bald Su Lun?

Looks change with the heart. Having changed the shell of his soul, both his temperament and facial features were becoming increasingly different from the original owner.

He didn't think that bounty hunters would find him based solely on this photo.

......

In addition to the fixed shops, "Shadow Alley" also had some antique dealers who claimed to be Wastelanders along the narrow roads.

They casually pulled out a piece of rag, put a few things on it, and claimed that they were ancient treasures retrieved from some ruin.

This gave Su Lun the feeling of visiting the Panjiayuan Antique Market in his previous life. All kinds of strange and bizarre things looked quite intimidating, but when viewed with the Eye of Omniscience, they were all "fakes"!

Although he had the "Eye of Omniscience," Su Lun didn't think he could come here to find a bargain, nor did he waste time identifying those fakes one by one.

Extraordinary items all had very special energy fluctuations, especially cursed materials. Even a layman could sense that the items were not simple.

Moreover, alchemists were also very knowledgeable professions. It could be said that almost every Wasteland hunting team had "appraisers" who were proficient in archeology and mysticism.

It was possible for one person to overlook something, but the possibility of everyone overlooking it was almost zero.

There were good things in the black market, but you definitely had to pay the corresponding price. You didn't need to go bargain hunting yourself; if you sincerely wanted to sell something, just ask the shop owner directly, and he would mysteriously take out good things that weren't on display in the counter.

After all, his wanted poster was still hanging on the wall, so Su Lun didn't plan to wander around the market.

His purpose in coming to the black market this time was to buy some array materials for "job change."

Kai had told him before that "Rosen's Alchemy Shop" had a good reputation and excellent goods.

After walking for a few minutes, he found that inconspicuous little shop in a corner of the market.

A simple copper bell was hung at the entrance of the shop. No matter how one entered the narrow shop door, they would bump into it.

With a ding, the shopkeeper would know that a customer had arrived.

The shop was very small. All three sides had glass counters, and the walls were covered with dense small-grid wall cabinets. Even the air was suspended with many displayed material samples using ropes.

Hearing the bell, an old man with glasses who was sorting materials emerged from behind the counter. "Guest, what materials do you need to purchase?"

Su Lun glanced at him, didn't waste words, took out the material list, and said, "I want six white crystals, thirty grams..."

But as soon as he started, the old man looked surprised, as if he had misheard. "You want white crystals?"

Su Lun: "What, you don't have them in your shop?"

The old man explained: "No, esteemed guest, I don't mean anything else. I mean, advancing to a 'Professional' doesn't require high-purity crystals at all. Ordinary yellow crystals are enough."

The shop owner sold alchemical materials, so he naturally knew that buying crystals was mostly for arranging an alchemical conversion array for job change.

He sold dozens of crystals here every month, and more than 95% of the people bought impure yellow crystals. Only a few would buy blue crystals with higher purity.

As for high-purity white crystals? No one in the Outer City needed that kind of high-end stuff.

Not only were they expensive, but using such high-end materials to set up ordinary job-change conversion arrays was a complete waste.

So he presumed that the guest in front of him had made a "slip of the tongue."

"Thank you for your kind suggestion, but I'm sure I need six white crystals."

Su Lun said in a deep voice.

It wasn't that he was ignorant, but rather that he already knew a lot of alchemical common sense and knew that he needed these materials.

For ordinary job-change ceremonies, impure yellow crystals were indeed enough.

But the [Rune Puppet] job-change material in his hand had a quality that reached the Gold level, so he needed equally high-end materials to arrange the conversion array in order to successfully change jobs.

"Oh, is that so..."

The old man glanced at him and didn't say anything more.

He took out something from his personal storage ring and introduced it: "I happened to receive a few from a group of Wastelanders yesterday. I originally planned to sell them to a large merchant in the Inner City, but I'll sell them to you if you want them. However, the price isn't cheap. Six pieces will cost a total of 12,000 Lisol."

Su Lun looked at the six palm-sized, crystal-clear crystals on the tray and nodded in satisfaction.

Although he didn't have the ability to judge purity, the Eye of Omniscience revealed that the name of this thing was [High-Purity White Crystal].

The old man asked again: "What else do you need?"

"Fifteen grams of Snowflake Stibium, eighty milliliters of Grade 4 or higher quality Mercury Salt liquid, eight portions of refined red copper powder, two hundred grams of lizard powder that is at least thirty years old, a green glow crystal..."

Su Lun didn't hide anything and directly listed the material list he needed.

He knew very well that there was no need to hide his purpose at all.

These material merchants had sold too many materials and were extremely shrewd. As soon as you spoke, they actually guessed what you were up to.

If he really went to different shops to buy them separately, the possibility of being targeted would be even greater.

"These are all very high-end materials... You may not be able to collect them all at once if you go to other shops, but I happen to have some stock left in my shop."

The old man muttered, obviously guessing that the guest in front of him was planning to set up a very high-level conversion array.

However, professional merchants wouldn't inquire about their customers' secrets. This was the rule of the black market.

Without wasting words, he took out various materials one by one, weighed them, and then quoted the price: "A total of 42,000 Lisol."

Hearing the quote, Su Lun took out the bonus that hadn't even warmed up yet with a straight face and said, "This is the money, please count it."

Just a few hours ago, Kai had told him that he had spent 8,000 Lisol to buy array materials when he changed jobs.

But Su Lun now spent five times that amount.

However, the good news was that now everything was ready, and he could change jobs.
