The auction house is a very large building with a cylindrical shape as a whole, with layers on top of each other, to say nothing of six or seven floors.

And its floor space is not small, almost as big as a knight academy.

In addition to the imperial-supported buildings of the Royal Academy, it is estimated that this auction site is also one of the best private buildings.

It seems that the owner behind this auction house should also have considerable strength, otherwise it is impossible to build such a large scale in a small city like Falling Star City.

This large-scale auction house should have a lot of well-connected leaders in all walks of life. Lin Mo decided to check it out first.

"Sorry, sir, the auction house is only open during the day. Please come back tomorrow during the day."

Lin Mo just walked to the door, but was stopped by the guard at the door.

Lin Mo was taken aback, and then soon understood.

It is the evening, and there are some underground auctions. It is estimated that no one is recommended, and it is impossible to enter.

Just as Lin Mo wanted to lie that he was the seller, he was suddenly caught by his shoulder.

"This is my friend. He just came here and doesn't know the rules."

Lin Mo turned around and hugged himself as a person wearing a black robe. His voice was also pseudophonic, and he could not tell who he was.

As the black-robed man said, he handed a card with repeated patterns to the guard.

"Okay, I know."

The guard took the card with both hands, and after careful confirmation, returned it to the man in black robes.

Then the guards let the door open and invited the two into the auction house.

After the guard turned and went back, the black-robed man immediately lowered his arm around Lin Mo.

He seemed familiar with this auction house, and quickly led Lin Mo to a secret door.

Opening the hidden door is a ladder extending downwards.

Lin Mo then understood that this auction house had hidden secrets.

The parts on the ground are used during auctions during the day, and auctions and transactions are not important.

And the real big transactions of this auction house are all carried out on this underground exchange.

Moreover, the underground auction is only conducted at night, and should be a membership system, requiring someone to recommend it to enter.

It can be seen how dark and complicated these transactions are.

When he reached the corner of the stairs, the black-robed man stopped, and Lin Mo also stopped.

"Thank you for your help, don't know how to call it?"

Lin Mo held his fist at the black robe man and asked softly.

"You are really a noble person who forgets things. Today we just made a transaction of fifty thousand gold coins. Have you forgotten?"

The black robe man snorted and said.

Fifty thousand gold coins?

Luen!

Although he couldn't see the other party's appearance, and the voice was specially processed, Lin Mo immediately realized that it was Luen when he mentioned the fifty thousand gold coins.

This little Nizi actually knew the way of this auction house.

"There are many people, and the underground trading is wild. This is my spare set of black robes. You should still use it."

Luen said and looked around, then took out a set of black robe and handed it to Lin Mo.

Although Lin Mo didn't want to make it seem shameful, he didn't care about it himself. In case someone attracted to someone with malicious intent, Lian Nuan Luen and the others might be unlucky.

Lin Mo is not a selfish person, so he still put on the black robe that Luen handed him.
