Facing the beautiful receptionist lady, Lu Ming directly took out both the green and blue crystal nuclei:

"Help me upgrade to the blue brand, the crystal nucleus is ready, and the excess will be sold."

White to upgrade green requires a white crystal nucleus, and green to upgrade blue requires a green crystal nucleus, both of which are sufficient for Lu Ming.

"From white, upgrade to blue?"

Miss Usher was obviously a little surprised, she had never heard of this two-level promotion, and the blue adventure group, this is already an elite adventure group in the mainland, there will be at least knights in the group, this kind of adventure group is rare even when the goddess treasure appears.

However, she was only surprised for a while, and when the receptionist lady saw the name on Lu Ming's form, her face immediately changed.

I didn't expect the person in front of me to be a brave man, no wonder she could jump two levels in one day, that is, three levels, and she believed it.

The receptionist lady hurriedly took care of their upgrade with a respectful look, and handed them a few blue adventurer signs:

"Your badge, Lord Brave."

After Lu Ming took the signs, he distributed them to An Leiya and a few people.

The promotion of the adventurer's union is based on the team model, as long as there are enough nuclear crystals, the adventurer level of the whole team will increase, but the adventurer group has a maximum number of eight people.

Of course, if you have the strength, you can also choose not to form an adventure group, as long as the crystal nucleus is enough, it is okay to only upgrade yourself.

"This is the gold coins you got from selling the nuclear crystal, 32 white coins, 17 green coins, a total of 202 gold coins, do you need to store them in your adventurer identity badge?"

Next, the reception lady settled his excess crystal nuclei as well.

"Save it in."

Lu Ming nodded, compared to the 10 million gold coins he got from the Sky Chamber of Commerce, the more than 200 gold coins at the moment were a bit inadequate.

Of course, what Lu Ming didn't know was that the purchasing power of two hundred gold coins in the royal capital was already very high, and ordinary civilians could not see such a thing as gold coins, 1 gold coin was equal to 100 silver coins was equal to 10,000 copper coins, and civilians were traded with copper coins.

After figuring out the affairs of the Adventurers' Association, Lu Ming took An Leia and the others into the shop area, wanting to see if there were any good things.

"According to these adventurers, the sixth floor is already the lowest floor, but it seems to be very big, and no one has found the boss's room so far."

After shopping around the shop for a while, I didn't buy anything, but the news was a lot, and An Leia on the side was already complaining with some sighs.

Lu Ming also nodded and told her:

"There is a goddess treasure in the boss room at the bottom, where not only is the complexity much higher than the first six floors, but the level of the monster has also entered a new level, and there are not many adventure groups that can enter there."

"Shall we get ready to go in sooner?"

Hearing this, An Leiya asked, since the sixth layer is so difficult, then did they also prepare well earlier, otherwise they would not be able to come out tonight.

"Let's see."

Lu Ming shook his head, there was Lifa's highest detection magic, and there were several high-level knights in An Leia, he was not worried about time at all, in contrast, he wanted to buy a map of the hidden room, the adventure was just to fight monsters, and it was fun to add a little treasure hunting.

The next moment, the heavens seemed to understand Lu Ming's thoughts, and when he hesitantly looked at the nearby storefront, thinking about which one would have a map of the hidden room, suddenly a gentle girl's voice interrupted Lu Ming's train of thought.

"That...... This gentleman, are you part of the adventurer team? ”

Lu Ming looked down, and at some point he walked in front of him, a young woman dressed in sackcloth, about twenty-four or five years old, with short black shoulder-length hair, very beautiful appearance, and a delicate figure, in short, a young woman with a lot of charm.

"yes, what's wrong?"

Lu Ming nodded, he didn't wonder why the other party suddenly found him, after all, he had a blue adventurer sign hanging around his waist, and it was extremely rare in this shop area, if the other party needed help or wanted to trade any valuables, it would be right to look for them.

It's just that, looking at the woman's level, Lu Ming was a little unsure of her purpose for a while.

The woman seemed to have found them because of the adventurer's identity card, and when she saw Lu Ming open her mouth to admit it, her eyes lit up, and she said a little anxiously:

"So, I wonder if you need a map of the hidden rooms of the underground labyrinth?"

The woman first looked around to make sure that no one else was paying attention, and then she took out an earthy yellow map from her linen clothes and whispered:

"My husband, who is also a knight of other adventure groups, discovered a hidden room from the underground labyrinth and secretly marked it on the map without telling his teammates."

An Leia on the side listened to the woman's words, a little surprised, she looked at the young woman, saw that she had an excellent personality and was beautiful, I don't know whose luck was so good to marry such a good wife.

But since the woman said that her husband was a knight, it should not be surprising.

"Then I don't know how much this lady plans to sell this picture."

Lu Ming chuckled and looked at the woman in front of him, waiting for her to speak.

"I don't know...... How about two or two thousand gold coins? My husband said that the price was the lowest......"

The woman was a little embarrassed to speak, as if she also felt that the two thousand gold coins were too large, but she didn't understand this kind of thing, so she could only listen to her husband.

Lu Ming glanced at her, and under her gentle face, he saw a trace of disobedience.

"Two thousand is two thousand."

Lu Ming didn't bargain with her either, if what the woman said was true, then two thousand gold coins was really the lowest price.

At this price, it is just enough to buy a level 50 jewelry item, in comparison, this kind of map of the hidden room can actually be sold for more than 3,000.

Hearing this price, An Leiya and the others also looked at this woman with great emotion, feeling that she was not only virtuous, but also very kind, and quoted the lowest price her husband said as soon as she opened her mouth.

Lu Ming looked at them like this, but shook his head.

Obviously, there is something wrong with the woman in front of her, not to mention anything else, let's just say that her level is a full level of 97, but it is even higher than An Leia.

It's just that she's been covering it up, so An Leia and Youlina of the same level, naturally don't see it.

If she wanted to say that she got the map herself, Lu Ming believed it, but she had to go to great lengths to find an excuse that 'her husband got it', so that Lu Ming had to doubt the woman's purpose.

The husband in her mouth may not exist at all, and there may be some problems with the identity of this woman, otherwise why would she go to great lengths to dress up as an ordinary person to sell maps?

Could it be the people of the mysterious force? This kind of mysterious style of doing things that don't want to reveal their identities is indeed very similar to them.

At this moment, Lu Ming already had a lot of thoughts in his heart, but in the end, he still transferred the three thousand gold coins to the woman's account with a smile, and took the map of the hidden room handed over by the other party:

"Well, happy trading."

Lu Ming looked at the woman for a long time, but the woman bowed like him without leaking, thanked him, and then left slowly.

The woman's expression and movements when she left couldn't see anything wrong.
