North Hades Sikong Island.

Due to the use of a long-distance teleportation array, Zhang Yang's time was greatly saved, making him arrive here in advance.

At this time, it was still more than 20 days before the exchange meeting began, but the island was already crowded with people, and a famous cultivator could be seen everywhere. Even those Jindan monks, who are usually rare, can be encountered from time to time.

You can even see a powerful demon cultivator or even a corpse cultivator strolling down the street calmly.

Sikong Island is located in the North Underworld, thousands of miles away from the coastline of the Terran Continent, which was originally an island inhabited by cultivators, and now it coincides with the exchange meeting of Guiyunlou held here, so it is naturally full of people.

This feels extremely fresh for Zhang Yang. After wandering around for a few days without hurry, I got a general idea of the situation on the island.

It turned out that only a very small number of these people gathered on the island came to participate in the exchange meeting in Guiyunlou, and the vast majority of them took the opportunity to come to the neighborhood to join in the fun, taking advantage of the large number of monks during the exchange meeting, setting up stalls nearby to sell the items in their hands, or taking the opportunity to buy the items they needed.

There are also some people who organize some small-scale underground exchange meetings before or after the exchange meeting, and the effect is also good.

After all, Guiyunlou organized a prefecture-level exchange meeting this time, and only a few people were qualified to participate after all.

An exchange meeting can create such a big benefit, which reminds Zhang Yang of large-scale events such as the Olympics in his previous life.

I have to say that the identity token of the Guiyunlou exchange meeting is still very easy to use, not only to be able to participate in that prefecture-level exchange meeting, but also to kill other exchange meetings on the island.

No matter who organizes the small exchange meeting, as long as you have the identity token of this Guiyunlou prefecture-level exchange meeting, you can participate in it at any time.

This was convenient for Zhang Yang, and with a fun attitude, he participated in several exchange meetings in a row. He is not picky, no matter how big or small the exchange meeting is, he just wants to increase his knowledge.

After a few days, Zhang Yang also had a lot of gains, in addition to exchanging a few magic weapons that he was more interested in, he also sold several magic weapons at a high price and raised a large number of spirit stones.

Zhang Yang started by killing people and grabbing treasures, and he has no shortage of spirit stones. However, after all, this prefecture-level exchange meeting is close to the highest level of exchange in the mainland, and if some good things appear in it, it will definitely cause crazy bidding.

Be prepared! This is what Zhang Yang thinks. I'd rather not use these spirit stones, or after the end of the day, I see the good things I like but miss them because I don't have spirit stones, it's a lifelong regret.

On this day, Zhang Yang walked out of his temporary residence as usual and strolled to a small market.

A small city like this is usually rare. However, on Sikong Island now, there are as many as one almost every day.

And the gathering of a large number of cultivators makes the Fang Market not have to worry about the flow of passengers at all, as long as the market is open, it will soon be full.

After paying the entrance fee for five spirit stones, Zhang Yang entered the market.

The current Zhang Yang belongs to the absolute rich level, and his net worth is rich, even if he is placed among the old monsters, he is also very rich. There are all kinds of spiritual stones, magic weapons, and exercises. There are fewer and fewer things that can make him look at them.

After turning around, I only bought two pieces of mysterious material that no one knew what they were. Buyers and sellers of materials like this are traded with a completely gambling attitude.

Of course, the reason why Zhang Yang made the transaction was that he didn't take that bit of spirit stone to heart at all.

He saw nothing else ideal, and was about to leave with a little disappointment, when suddenly, a piece of gray iron lit up in his eyes.

This piece of gray iron turned out to be exactly the same as the one he encountered when he first participated in the Fang Market near Maiji Town.

Similar irregular shapes, exactly the same breath, all have a strong calling power for Zhang Yang.

That's it!

As he walked in, feeling the increasingly strong calling power in his heart, Zhang Yang had already made up his mind to take down this piece of gray iron no matter what.

The owner of the gray iron is a middle-aged monk who builds a mid-level foundation. In addition to this mysterious gray iron, there are also two magic artifacts next to it. Obviously, in the eyes of this middle-aged monk, the value of this piece of gray iron is far higher than that of those two magic weapons.

Now Zhang Yang is rich and rich, as long as the other party is willing to sell, he can afford the price, but he doesn't have to engage in any tactics to attack the west, and directly stepped forward to pick up the gray iron.

The gray iron tentacles immediately felt like flesh and blood blending, and the whole body was extremely comfortable.

At this time, the voice of the middle-aged monk sounded:

"This senior, in the next piece of gray iron, wants to exchange a fire return pill, if the predecessor has a fire return pill, in the next can immediately offer this piece of gray iron. ”

The Fire Returning Pill is an elixir used by monks who practice fire surname spells, and taking one pill during the foundation building period can raise the realm by one order, and the end is extremely precious.

However, Zhang Yang once obtained several Fire Returning Pills in an ancient ruin, this thing has no effect on him now, and if it is used for trading, it will be distressed at all.

"Oh, there is a fire return Dan deity. However, what kind of gray iron is you, it is worth a fire pill?" Zhang Yang rolled his eyes and asked.

Originally, this middle-aged monk didn't have much hope when he saw that Zhang Yang was black and stiff, and the reason why he didn't dare to snub him was because the other party's strength was completely above him.

Now I heard that the other party really had a fire to return the pill, and it seemed that it was an intentional exchange, so I immediately became enthusiastic.

"Don't hide it from the seniors, and the juniors don't know what this thing is. When the middle-aged monk said this, his old face was also red. I don't know what it is, so I offered to exchange it for a Fire Returning Pill, which does have a bit of a greedy taste.

Xu was afraid that Zhang Yang would not be satisfied, so the monk then said: "However, the junior can be sure of one thing, this gray iron is definitely not an ordinary thing. The younger generation cultivates the law of the fire surname, and when he got this piece of gray iron, he tried to refine it, but he was unsuccessful. The younger generation has a close friend, who is a disciple of the refining master Yechen of Dayu City, Yinchuan County. Later, the younger generation once found this close friend and begged him to identify this piece of gray iron. As a result, not only did the best friend not know about it, but after exhausting all means, he still couldn't help the piece of gray iron, and finally only said that it was not a mortal thing. Therefore, although the younger generation does not know what it is, if they can't exchange it for what they want, they would rather collect it than exchange it at will. ”

Yechen, Zhang Yang naturally knows. Before sending Shangguan Mo'er back to Daxing City, Shangguan Mo'er's daughter had taken him to Yechen to repair a large number of mechanical puppets.

This Yechen does have some means in refining weapons, and there are disciples all over the world. As for how much vision his disciples can have, it's hard to say.

However, Zhang Yang didn't care about other people's opinions, he had long been determined to take down this piece of mysterious gray iron.

He immediately spoke: "The deity intends to exchange this mysterious gray iron, but you have to tell the deity where this mysterious gray iron came from. In this way, it is good to judge what it is. ”

The middle-aged monk's eyes lit up when he heard this, but he had nothing to hide, and said:

"The younger generation is originally from Sikong Island, and in addition to retreat and practice, he usually teams up with everyone to go deep into the Northern Styx Sea to explore. This gray iron was obtained by the younger generation from an ancient ruin during an expedition. However, the ancient ruins are extremely dilapidated, and they have been entered by countless people, so it may not be easy to find any more clues. However, if the seniors want to investigate, the juniors can tell them the location. ”

At Zhang Yang's request, the middle-aged monk took out a jade slip, burned it with his divine sense, and soon a simple map was formed.

Zhang Yang checked it and frowned:

"The Arctic Iceberg? The ruins you mentioned are actually located in the Arctic Iceberg, although it is not the central area of the Arctic Iceberg, and I am afraid that it is not something that you can reach as a small foundation building monk, right?"

With the words, a powerful momentum spread from Zhang Yang's body, and a huge coercion pressed towards the middle-aged monk.

If the other party dares to play any tricks, Zhang Yang doesn't mind giving the other party a small lesson, and even chooses the opportunity to kill him.

Feeling the momentum on Zhang Yang's body, the middle-aged monk's face immediately changed, and he hurriedly said:

"The seniors were angry. Naturally, the younger generation did not dare to deceive the seniors, and this mysterious gray iron was indeed obtained from a relic of the Arctic Iceberg. That was more than ten years ago, when the juniors went with a team, not alone. There are monsters all over the North Stygian Sea, and if it is just the younger generation himself, it is naturally impossible to reach the Extreme North Iceberg safely. ”

The middle-aged monk said extremely sincerely, and the other party did not seem to have any need to deceive himself. Zhang Yang retracted his momentum.

"Team, if that's the case, it's not impossible. ”

Since he chose to believe, Zhang Yang no longer embarrassed the other party, and with a flick of his fingers, a small black bottle was thrown over.

The middle-aged monk took it, uncorked the bottle and took a look, and immediately showed an expression of ecstasy.

Zhang Yang smiled slightly, stretched out his hand, put away the piece of gray iron, and turned to leave.

After the middle-aged monk got the Fire Returning Pill, he didn't even bother to set up the stall anymore, and immediately packed up his things and rushed back to the cave to retreat.

...... Back in the cave, Zhang Yang flipped his hand and took out all the two mysterious gray irons, and suspended them in front of him.

He has studied this mysterious gray iron a lot, usually attacks with his claws, tempers it with the fire of the Nine Flames, burns it with the Yin Fire released from his body, probes with his divine sense, and recognizes the Lord with blood...... Almost all the means that can be used have been used, but they have never achieved any effective effect.

Now, he looked at it again, and could only put it away helplessly.

I was sure that these two pieces of mysterious gray iron would definitely be of great benefit to me, but I didn't know where to start, and this feeling was extremely unpleasant.
