This time the mission was quickly completed, and Chu Nan left after this to find his partner.

At this moment, they have already come to the skyscraper, the skyscraper is very large, like a huge mushroom, small at the bottom and big at the top, Chu Nan is really worried about whether this will collapse.

The skyscraper is the most magnificent building in Io City, and it is also the largest trading center in Io City.

Next, a group of people spun around in this so-called Ferris minion.

Inside the skyscraper, people come and go, here, there are people from all over the continent and some other regions, all strolling around here at this time, but no one dares to make trouble here, mainly the strict law enforcement officers here.

+9 In this area, it is not uncommon to see law enforcement patrolling here.

A group of people are wandering around here, the first floor, is a place to sell things freely, here, you can exchange at an equal price, as long as both parties are willing, you can reach a consensus, and all transactions here will be protected by Io City, which is why many people exchange here, because they are not afraid to buy fakes.

"Don't miss it when you pass by, the best elixir in exchange for magic crystals. Don't do anything else. ”

As soon as he walked past a stall, Chu Nan saw what was written on it.

"How are these elixirs and magic crystals exchanged?"

Chu Nan walked over and asked.

"Grade-level magic crystals in exchange for grade-level elixir."

The man said.

After hearing this, Chu Nan immediately dodged and left, the exchange of ranks, although it sounds fair, but it is definitely not that simple, you must know that although the elixir is precious, it is not very useful after all, in many cases, it is not used, and the magic crystal is different, he can help the monk recover the energy in his body, and he can also help cultivation, in some times, it is even more helpful, but the elixir is different, he is useless in many cases, although he can save his life at a critical moment.

"Wait, I'll give you a cheaper, two grade-level magic crystals in exchange for three grade-level elixirs."

This master was a young man, and when he saw that Chu Nan was leaving, he immediately shouted.

Chu Nan didn't speak, turned his head again and left.

"Three magic crystals in exchange for five baht elixir, no more."

The man almost gritted his teeth at this time and said, he finally waited for a customer, he didn't want to let it go, but this was already the limit of what he could bear.

"You're short of magic crystals?"

Chu Nan looked at the man suspiciously.

"Hmm."

The man didn't hide it, nodded and said.

Facing such a man, Chu Nan didn't know what to say for a while, I really didn't know what this young man was hot-headed or what he was doing, so he had to exchange things like this.

Eventually, under the guidance of Timo and Tinker Bell, he purchased the best elixirs.

Although he was very unhappy on the surface, he was actually happy in his heart, this time he really earned it, after all, he had too many magic crystals, which two people came from at the beginning, I really don't know where they came from so many magic crystals.

Although he has a lot of magic crystals on his body, most of them are low-level existences, and this time he wants to find some high-level magic crystals, of course, he just came with hope, whether he can find them is still uncertain, and he needs to try his luck.

Don't say anything, Chu Nan and they searched here, and searched the entire first floor, Chu Nan and they didn't find the existence of high-level magic crystals for sale, but they also found something suitable for themselves, Aya found a defensive secret protection, and the little black dog also found something suitable for him.

The second floor is no longer a free trading area, but a counter platform, where there are a lot fewer people, but there are still a lot.

Looking for the entire second floor, Chu Nan and they still didn't find the right thing, the things on the second floor were really too low-level, and they were no longer suitable for them.

Then they entered the third floor, the first three floors of the skyscraper are open, and it is not so simple to go up further, and they need to prove that they have the strength and financial resources.

However, Chu Nan and they are not worried, Chu Nan's economy is very sufficient, although he just paid all the money a few days ago, but his current funds are still a lot, you must know that his former source is thousands of people in the entire Ionia.

Smoothly came to the fourth floor, here, the flow of people is obviously too much less, after all, it is no longer an open existence, and the number of people entering here is relatively too small.

Looking here, they finally found the target and found the sixth-order magic crystal, although the sixth-order magic crystal is still not too high, but after all, the number of demonic beasts is much less than before, and the magic crystal of this level is already quite good.

Subsequently, Aya told Chu Nan that he also needed a large number of energy magic stones, these things were used for research, since they were research, he was very supportive, after all, he was also waiting for the moment when that thing was studied, and when the fighter appeared, he drove the fighter jet and flew in the sky, which was really called a comfort.

Then, without saying much, he found the right Philosopher's Stone and bought it.

The little black dog on the side rolled his eyes, he didn't expect Chu Nan to be so rich, he now wanted to give this guy a stick from behind, and then robbed him of his things.

However, because all the funds were spent just a few days ago, I want to take out too much for a while, or it is not so simple, I can only come little by little.

In the end, when they finished shopping here, they had already spent a lot of money, and almost consumed all the gold he had earned.

At this time, Chu Nan was really helpless, he felt very rich, but he didn't expect it to cost so quickly.

But here you can not only buy things, but also sell things, although he got a lot of them last time, but he still has a lot of things on him.

In the end, he sold the low-grade magic crystals below the third order, and at the same time, he also sold a lot of low-grade elixirs, which he almost couldn't use, so it was better to sell them here in exchange for some useful things.

On the top of the skyscraper, there should still be good things, but Chu Nan did not continue to go up, mainly because there was no money, and then there was enough things they got now.

Just when Chu Nan and the others wanted to leave, they were stopped.

"Seeing that you are purchasing magic stones and rare metals, I don't know if you are not interested in the Thousand Forged Silver Sense."

The person who spoke was an old man, and the old man looked a little vicissitudes, and the years left an indelible mark on his face.

"Thousand forged silver?"

Chu Nan was puzzled, he really didn't know anything about these metals and the like.

"You have a thousand forged silver."

Aya's voice suddenly rose several times higher.

Although Chu Nan didn't know what this thing was, he knew from Aya's reaction that this thing should be very precious.
