Behind him, Lifa pulled the corner of his coat and told him:

"Lord Demon King, this is a complex underground corridor, there are many passages, intricate, please follow me."

As the head maid, she is proficient in detection magic, and wherever there is a room and any passage, she can appear in front of her eyes at the first time.

Lu Ming nodded, it was indeed convenient to have Lifa here, but in a quarter of an hour, they appeared at a dark entrance.

Although the entrance was not very bright, there were many precious metal gems inlaid around it, which made Lu Ming can't help but muttered in his heart:

Could it be that this is the kingdom's underground red-light district?

"Who are you?"

As he pondered, a hoarse voice came, and out of the entrance stepped out a strange man dressed in a black robe with a guard sign wrapped around his waist.

This person has more than 50 levels of strength, and according to the modern division of strength, he is already a knight.

Lu Ming frowned, even though he came to the royal capital and saw a lot of people, including the carriage of the Viscount Deco who passed by him before, none of them were above level 50.

I've finally met one now, but it's just a guard?

Doesn't it mean that knights are all big men even on the side of the royal capital?

Lu Ming couldn't help but wonder what kind of place this was.

It's just that before he could suspect it, the knight in charge of guarding had already seen the holy sword on Lu Ming's waist, his face changed, and he ran towards the entrance.

His face was panicked, obviously he didn't want someone like the brave to find out here.

Seeing this, Lifa snorted coldly, instantly pulled out the two black swords on her waist, and appeared behind the other party in a strange shape.

The knight had barely turned around when he was shocked to find that two terrifying rays of magic had pierced through his body, and his entire body was engulfed by black magic before he could even use magic to fight back.

Not even a drop of blood remained, and the knight was simply executed in secret.

"Lord Demon King, this is the end of the passage, and there are quite a few people in it."

After eliminating the knight, Lifa stood in the position where the other party disappeared, put away the black sword at his waist, and whispered to Lu Ming.

"Well, let's go in and have a look."

Lu Ming didn't say anything, and Lifa got into the entrance, and there was a black curtain covering the entrance, and after the two of them entered, they found that there was a huge meeting hall inside.

This is a meeting hall of several thousand people, and the top is lined with gems to put out nine bright characters of 'Sky Chamber of Commerce Underground Auction'.

On the front platform, a black-robed man was presenting the item, and it looked like the auction had been going on for a while.

However, although the venue was large, there were not many people inside, and there were two or three hundred sparse people, scattered and sitting everywhere.

When Lu Ming walked in, no one paid attention to him, and the auction here was surprisingly orderly.

He immediately felt that this place was very strange, so he casually found a seat in the back row and sat down with Lifa.

"Let me see this mysterious auction, it's all about fun."

Lu Ming waited expectantly.

It turned out that some of the gadgets auctioned here were too much for him, the demon king who owned the entire Demon King's Castle collection.

He was about to fall asleep when he saw it, until he tilted his head and saw a rabbit girl shuttling in the area, Lu Ming suddenly became interested.

beckoned, and Lu Ming called the waiter over.

"Sir, what is the matter with you?"

The so-called rabbit girl in charge of hospitality, of course, is played by a young and beautiful woman in the human race, wearing a revealing rabbit girl costume with black silk rabbit ears, no matter how you look at it, it is exactly the same as the rabbit girl in a certain world before Lu Ming crossed over.

It seems that no matter what world this is in, this man's interests and hobbies are the same.

Lu Ming coughed lightly, of course he couldn't expose him to stop the other party, in fact, he was quite interested in the other party's dress, and he began to talk casually:

"We didn't bring enough money with us when we went out this time, can we mortgage items here?"

"Of course, sir."

The bunny girl nodded her head as a matter of course, and the two black bunny ears on her head swayed as if she had become accustomed to such requests from her guests.

This is not a simple auction house, every auction item is sky-high, and if every customer is trading for gold coins, then they can't count them.

Therefore, this method of collateralizing goods is actually the most commonly used means of trading.

"I don't know the guest, what do you want to mortgage?"

The rabbit girl looked at Lu Ming with a smile, this Sky Chamber of Commerce didn't know what the way it came from, even these receptionists at the bottom were very beautiful, and with Lu Ming's knowledge, they all had a pleasing sense of comfort.

However, in the face of the rabbit girl's questioning, Lu Ming hesitated.

When you think about it, he really doesn't have much value on him.

The holy sword is very valuable, but can the holy sword be sold?

He just wanted to sell it, but no one dared to accept it.

In this regard, Lifa beside Lu Ming immediately put his hand on the two black swords on his waist, wanting to mortgage them for the Demon King.

It's a pity that Lu Ming held her hand and shook his head at her.

First, the two black swords on Lifa's waist are already very affectionate after being with Lifa for I don't know how many years, and Lu Ming doesn't want Lifa to sell his precious weapons for him.

Second, Lifa's two weapons, although they don't even have a name, are a pair of weapons that are not in the flow for their Demon King Castle, but in this era, it is shocking to the world, a pair of 400-level dual swords, it is big news to take it out, Lu Ming doesn't want to make trouble.

This third is that Lu Ming suddenly remembered the ring equipment he found from the brave package before.

"Look at this thing, it's worth it."

Lu Ming stretched out his hand and took out a magic ring with a blue streamer.

"This is, a country-level treasure?!"

As soon as the blue ring appeared, the bunny girl covered her mouth in surprise, and there was something incredible in her eyes.

Level 200 equipment is the top equipment in a country, and it would be good to have one or two pieces in the general kingdom.

This can also be seen how much the kingdom has paid to win over the brave, and even the only heirloom treasure in their palace has been given away, which has led to this marriage.

"For such a thing, our Chamber of Commerce can't give you the full price for the time being."

The beautiful face of this rabbit girl usher showed a little embarrassed, there is no way, the transaction of country-level treasures, even some kingdoms can't take it out, although their Sky Chamber of Commerce is wealthy, but after all, such a large amount of money is not something that her small receptionist can decide.

"It's okay, give me as much as you can."

Lu Ming didn't care about this, anyway, this ring was just a dispensable thing to him.

After a moment's hesitation, the bunny girl usherin spoke:

"So...... How about giving you 10 million gold coins first, which is a reserve price, and the remaining fraction, I will take you to the person in charge to make up for it after the auction is over. ”

This 10 million gold coins is already a number of gold coins that are difficult for the king of a kingdom to come up with, if it weren't for the fact that this auction is an important auction held every four years by their Sky Chamber of Commerce, and the usher above gave them a large amount of money to help the guests exchange for gold coins, otherwise she would not be able to take out so much as a small receptionist.

Rao is like this, Lu Ming has already squeezed all the gold coins on this rabbit girl's body.
