Hearing Bei Shenchen's words, Lin Xu smiled and said, "I really have a lot of spiritual construction items in my hand that need to be exchanged for money. "Lin Xu has a lot of construction items and some martial arts in his hand at this time, and he should be able to exchange a lot of money.

It's just that these things are not all his own, but from Yang Feng and the ghosts.

In the auction house, Lin Xu took out many of the items he got from Yang Feng and the ghosts, among which there were many fourth-level spiritual construction items, each of which was worth nearly 10,000 yuan.

There are also some spiritual martial arts, this martial art is even more rare, and its value is very expensive.

In addition, there are also some demon beast bodies and demon crystals, these things Lin Xu took out all of them, this is a burden to him, and it is useless to ask for them, it is better to convert them into gold coins.

Finally, Bei Yingchen sorted out all the items, totaling 250,000 gold coins!

Yang Feng and the ghost spirit have dominated Qingyan City for so many years, and the treasures stored are only 250,000 gold coins, for Lin Xu, the amount of this gold coin is not too huge, but for others, this is already an astronomical amount.

Perhaps for Lin Xu in the past, such gold coins were something he could never have dreamed of.

But as his strength grew, and with the expansion of his circle, the amount of gold coins needed no longer increased, and he had been in Qiongzhou City before, and he only had contact with some small trading houses and auction houses, and he didn't need to spend much gold coins. And now Lin Xu is in contact with a large auction house, and the people he comes into contact with are also some spiritual constructors and some imperial powerhouses, maybe others see Lin Xu as a rich man, but only he understands that in this big circle, he is too poor.

Now Lin Xu already has 350,000 gold coins, which is already a lot of wealth, and Lin Xu is just looking for the demon crystal of the fifth-order demon beast this time, and he doesn't care about other items, but for the sake of insurance, Lin Xu still took out a few of his own construction items.

In the past, Lin Xu also constructed a lot of three-grade spiritual construction items, although these construction items only had a few thousand gold coins each, but fortunately, the number was huge, which also made Lin Xu exchange for 50,000 gold coins.

At this time, Lin Xu was carrying 400,000 gold coins!

"It should be enough!" Lin Xu said secretly in his heart, even if he encountered some more valuable items, the money was enough to buy them.

Then Lin Xu left here, waiting for the auction to start three days later.

During this period, Lin Xu lived in Tianyuan Curie. For Lin Xu's arrival, Master Yun was obviously extremely happy.

"Do you want to participate in the underground auction?" Hearing Lin Xu's words, Master Yun said in surprise.

"That's right, I need some fifth-order demon beast crystals. Lin Xu said.

"Well, there are indeed these things in this auction, and these things are not valuables in them, even the demon crystals of the sixth-order demon beasts, they even exist in them, and some of the earth-level ** have been taken out for auction, and there are also many fifth-order construction items......" Master Yun said, he obviously knew something about this underground auction.

And when Lin Xu heard it, he was also very surprised.

Ground level**, this is definitely a real treasure, fifth-order construction items, and even six-grade martial arts, this auction is indeed different from the outside world, it can be described as a real auction conference, there must be a lot of strong people here.

It's just that Lin Xu doesn't care about these, although the ground level ** is strong, but the Heavenly Reverse God Scroll ** on his body must be of higher grade, and for some constructed weapons Lin Xu is not lacking, this Heavenly Xuan Sword is even stronger, and now Lin Xu is also extremely easy to use.

Not only that, Lin Xu also possessed the Heavenly Xuan Divine Sword Technique, so these things were not attractive to him.

It's just that Master Yun told Lin Xu that there are usually unexpected items to be auctioned at this auction conference, and the auction conference is generally not held, and there is no fixed time.

It may also be held once every six months or once every three years, and as long as there are treasures, an auction meeting will be held.

Every auction has exciting items, which also makes many strong people come to this underground auction to auction items, and even Feng Zhong, Cangyang, the powerhouses of the royal family, and the cultivators of the Lingyun Sect will also participate in this auction!

After all, the treasures here are really endless, and they are often unexpected, and they may have their own items.

And this auction conference is even more well-known, it seems that some very powerful treasures are going to be auctioned!

"Lin Xu, to participate in this kind of auction, it is best to put hundreds of thousands of gold coins on your body, the people here are a group of real rich people. Master Yun said with a solemn look in his eyes.

Lin Xu also knew quite well that just hearing the names of Feng Zhong and Cangyang, Lin Xu already understood that the person who participated in this auction conference could be said to be the richest person in the entire empire.

Sixth-order spirit constructor, any spiritual constructor can easily exchange hundreds of thousands of gold coins.

"If I really come across any treasures, it seems that I don't have enough gold coins. Lin Xu sighed secretly in his heart, but there were a lot of things that were really valuable to Lin Xu.

This Tianxuan Sword alone is almost a sky-high price, but Lin Xu will never be able to take it out and convert it into gold coins.

I asked Master Yun again about some things about the auction conference, Lin Xu went to his secret room, the auction conference still has three days, it seems that he should also prepare more money in these three days, and Lin Xu makes money very quickly, the fourth-level low-level spiritual construction items, he can still construct two pieces in one day, and each one is worth 10,000 gold coins, so in three days, it is not a problem to increase 60,000 gold coins again.

For three days, Lin Xu really constructed six fourth-level low-level spiritual construction items, and the royal auction house also exchanged 60,000 gold coins for him again, and Lin Xu at this time had 460,000 gold coins on his body!

This is also the time that Lin Xu has had the most gold coins since he became a spirit constructor!

At the same time, the long-awaited auction has finally begun, and it is located in a huge underground auction hall in the center of the imperial capital of the Northern Underworld Empire.

The people who can participate in this auction are all people with a lot of assets, but these people are all masked into the auction house, after all, on this continent, killing people and seizing treasures is very common, not to mention that they are not the strongest people in the Northern Underworld Empire, so it is safer to be masked.

And Lin Xu and Han Xiaoqi obviously prepared in advance, and each brought a hat, this time, the demon crystal of the fifth-order demon beast, Lin Xu was bound to get.
