This abandoned mine system is not small, and after special development, there are nearly 100 large and small interconnected mines, and the host of the black market gives the mines a serial number, and the specific location of each market opening is uncertain, people like Lin An who enter the black market only know after getting the number in the valley. 「」

Holes 48 to 52 are connected together, of which hole 50, which is a full multiple of ten, is the largest, and is the main cave.

When Lin An and the others entered, the cave was already bustling, with all kinds of voices and smells mixed together, as lively as a village market.

The main cave is mainly used for ore trading, and the black market has a considerable amount of ore in and out every time it opens, and due to the different directions of the western and central battlefields, the loot harvested is also of different categories, and the black market trading is meeting the needs of both sides for trading.

Each entrance to the mine is set up with a tax collection checkpoint, not to mention the vendors who enter and exit, including Lin An, who just come to buy things, must also pay taxes, of course, coins are not the only hard currency circulating here, and the tax money can be completely replaced by some unpurified ingots. After all, there were almost no people who still carried a large pile of gold coins on the northern route, and the black market trade mainly relied on barter, so that it could slowly develop into hard currency with ore.

There was a bunch of people crowded not far from the entrance of the cave, there was a simple notice board, recording some of the types of transactions and buying information that day was open, Avril was obviously here for the first time, and looked over there with some curiosity, Lin An saw it, and said a few words to Latins. 「」

Latence nodded, and trotted over to the notice board to squeeze into the crowd for a while. found Lin An and others in the mining trading area, and said in a low voice:

“…… The main item of the transaction is the ore type of this campaign, but there are a few pieces of information about the purchase, and the purchase of aquamarine, pyrocine copper ore and refined concentrate at a high price. ”

"Huh. Aren't these two the main materials for refining neutralizers? "After all, Avril has just come down from the front line, and her sensitivity is still very high, and she can tell the clues from the ore types that these two attributes are repulsive at a glance.

Neutralizer is a basic formula that is used on a large scale. It is used on a large scale in medicine, alchemy, etc., just like concentrated sulfuric acid is to industry, but strictly speaking, it is not a raw material, but a solvent bottom and catalyst.

There are many different mature formulations of neutralizers, and the ones with aquamarine and pyrocaneous copper as the main ingredients are not the best kind, but they are undoubtedly the easiest to obtain on the ice field, and pyrocaneous copper and aquamarine are not rare minerals. "" occurs as an associated ore in many minerals.

The purchase information of the two appeared on the notice board, and it was obvious that the number of purchases behind it was not small, and there were not many forces that could have such a large amount of high-priced purchases. Seeking to buy on the black market is tantamount to losing all your face, and even the entire logistics system can't raise your head in the army, and the logistics department can't afford to lose this person, and it doesn't dare to make such a big show.

Lin An smelled a strange smell behind him, glanced at Avril and Sidney, and his eyes happened to touch Sidney, but Avril was talking to Sidney, and was diverted from the previous topic. Didn't pay attention to Lin An's movements.

Lin An turned his head sideways and said a few words to Latins, who looked at the others, led the way to the entrance of the cave, and disappeared after a while.

Lin An and the others continued to walk forward as if nothing had happened, stopping and stopping, buying some of the rare ores that appeared in small quantities on the stalls from time to time. He even received a piece of high-quality black crystal that was not recognized by the stall owner at an inconspicuous stall in a corner.

Originally, the team of four people had been pulled apart, Sidney and Avril were closely followed by Helm, walking in front, and Lin An was left behind a little farther away, but Lin An's delay in receiving the black crystal led back to Avril and Sidney, and happened to see that Lin An had already handed out the small bag of platinum ore ingots and took the black crystal into his hands. 「」

Lin An's vision was quite accurate, this stall was walked by Avril and Sidney first, but they didn't find the dusty black crystal, until Lin An made a move, Avril realized that she had missed the opportunity to earn this rare high-quality black crystal at a low price.

Sombra has a rare mana inclusion, which can be repeatedly infused and extracted, which is equivalent to an extra portable small magic pool-

If the effect is only like this, it will not become a rare gem that mages dream of, and more importantly, high-quality black crystals can be refined with ores that meet the attributes, and black ghosts can be refined, which is a real high-grade alchemy product, which can help mages improve the progress of opening up the magic pool, and there are no aftermaths and side effects, it is a treasure to accelerate the progress of cultivation, and it is really hard to find.

It is said that when building a mage tower, each mage must prepare at least one piece of black ghost for their main meditation room.

Lin An could fully feel Avril's envious burning gaze after recognizing Sombra, and looked at her thoughtfully, the faint gaze made Avril's heart skip a beat, but she quickly recovered, but Lin An didn't wait for her to speak, didn't put away Sombra, and handed it to Sidney. 「」

Sidney didn't even look at it and took it into the space, and the natural behavior between the two dispelled all of Avril's thoughts—

She can afford to provoke Lin An, but she can't afford to provoke Master Elvis who has a ** teacher behind her, and Master Elvis who has a ** teacher as a teacher does not necessarily lack this black crystal, but she will never allow her to covet this black crystal that Lin An transferred to him.

What's more, judging from the tacit understanding between the two that they don't need words, the stability of the relationship between the two is not formed in a short period of time at all, and she is difficult to shake.

Avril was frustrated, feeling that she had done useless work on the black market this time, and that she had missed out on a precious piece of black crystal, and that she was still considered a competitor.

Originally, Avril thought that although she couldn't compare to Lin An in rank for the time being, her potential was far higher than her, and she had her own merits in terms of appearance.

But judging from Lin An's eyes when he found the black crystal that they had missed among the many items in the stall, her magic foundation was far more stable than hers, and even worse than Master Elvis as a disciple of the ** master, coupled with the momentum that was occasionally inadvertently revealed, it was enough to show the background of this female mage, and her origin was probably not simple. 「」

Avril suddenly dispelled the idea of wanting to compete with Lin An before, her brother was right, this Master Lin should not be underestimated, before figuring out her origin or getting Master Elvis's clear attitude, it was not suitable to have a bad relationship with this female white robe, after all, the attraction of Master Elvis was just an advance bet, but she might need to pay for her future and life.

After thinking clearly about her brother's intention to admonish herself, Avril clarified her position, and her praise for Lin An was a little more sincere:

"Master Lin's insight, my brother once said before, I was still a little confident, but now I know that I still have a lot to learn!"

"After all, I am older than you, and when you reach my age, your achievements will not be lower than mine."

Lin An was a little surprised by Avril's change in attitude, she didn't notice her intention to deliberately isolate her from Sidney, but she didn't take it to heart, now seeing Avril's attitude change, she vaguely felt that she was more restrained in her attitude, obviously quite aware of words and feelings, and had a rare prudence and rationality at this age.

"Hey, why is your squire missing?" Avril seemed to have discovered something, looked left and right, and asked Lin An softly.

She is indeed a little beauty, with a lively and delicate beauty that really belongs to the eighteen-year-old, and she likes to use modal words when she speaks, but Lin An doesn't feel disobedient at all, thinking that if it is a man, it is difficult to refuse such a little beauty.

It's a pity that her target is Sidney, which is destined to be fruitless, the body transformation of necromancers is destined to be physically weak, and normal women will not be willing to partner with necromancers who deal with negative energy all day.

"He's gone to help me search for goods from other stalls...... Well? He returned, and it didn't seem to have much to gain. ”

As Lin An was talking, he saw Latin appear at the entrance of the cave, Lin An raised his hand to summon it, and he found where they were.

Latin hurriedly trotted over, a little panting, but he didn't sweat much, and his hands were indeed as Lin An said, and he didn't hold anything, so Avril looked away disinterestedly.

The group continued to move forward, and Latin followed behind, approaching Lin An and whispering the purchase information he had seen on the notice boards of the other holes.

Lin An nodded lightly, and slowly lowered his eyes:

As Avril said, although there are quite a few materials used to disguise the purchase information, with Lin An's familiarity with the potion, he can still see at a glance that the materials in the purchase information on several bulletin boards add up, which happens to be almost the same materials used to make zuò neutralizer.

Lin An felt that the mysterious aura was even stronger.

She thought for a moment and sent a message to Sidney, who did not pause and continued to walk towards the entrance of the cave and into Cave 51.

Avril did not deliberately cling to Sidney this time, but carefully inspected the stalls passing by as she walked, it seemed that Lin An's previous Xiaolu had made her want to win, and she also wanted to find dusty treasures from these stalls.

A mountain pearl in a stall caught her attention, and when she successfully bought the thumb-sized mountain pearl, she looked up to find that Lin An and Sidney were gone, followed by Helm and Latins.

Seeing her look up for the two, Helm hurriedly said:

"Mage Avril, the two mages have something to do temporarily, they need to leave, leave us to continue to follow you, if you don't see them come back when the black market is over, you don't have to wait, we will escort you back."

"What about them? Not coming back before the black market is over? Avril was surprised.

"How can you explain the master's affairs to us!" Helm smiled, "But Mage Avril doesn't have to worry about security, this black market is in good order, and we've been here many times." ”
