After putting away the cold iron stored in the North Sea, Gu Meng calculated carefully, according to the preciousness of these things, he would probably only need to give one-tenth of Guijian Pavilion to be able to pay off the "debt" owed by Zhishan, and then the rest of the things could be exchanged with Guijian Pavilion.

But after all, the other party had helped Jishan before, so Gu Meng was ready to take out some more and return it to Guijian Pavilion, as for the Beihai side later, Zheshan could not send people to mine it for the time being, but Guijian Pavilion's sword cultivation was in the Star Realm, maybe the two sides could cooperate.

Of course, that's all for later.

However, before leaving, Gu Meng wanted to know how much cold iron there was under the North Sea.

Although Bai Yuchen said before that mining requires the cultivation of the Starry Realm to withstand the cold of the seabed, Gu Meng has now reached the peak of the Flying Light Realm, and his whole person's physique is not worse than those Starry Realms at all, and he has learned the complete Bai Yin Technique, and it is not difficult to enter the bottom of the North Sea and explore the cold iron.

Under the leadership of Bai Yuchen, the two came to the plain outside the Snow City, which was still snowy at the moment, and this place was like this all year round.

Bai Yuchen walked in the ice and snow, and spoke slowly, "I don't have to tell me about the matter between you and Liuyi, if you don't like it, you don't like it, and if you like me, I won't stop you, but you have to understand that if you are together one day, you will have to protect her." ”

As a father, although he can not interfere with his daughter's choice, Bai Yuchen will definitely not care about her.

Gu Meng opened his mouth, did not speak, and walked through the battlefield, although he still didn't have any special emotions towards Liuyi, but compared to before, it was indeed better.

"There are so many cold irons at the bottom of the sea that you can't count them, but you don't need to go to the sea to investigate. Bai Yuchen paused for a moment, "The North Sea is too cold, and there are no creatures in the entire North Sea. ”

Speaking of this, it aroused Gu Ming's curiosity, and he thought about it and asked, "Dare to ask Sect Master Bai, why is Beihai so cold?"

Beihai has existed for more than 10,000 years, but why is it only here in the whole world that is icy and snowy all day long, and it is extremely cold, this is not mentioned in those ancient books that explain this world, in fact, since Gu Meng knew that there were so many geniuses in this world 10,000 years ago, a new idea has been born, that is, after experiencing that war, not only has a history of the entire world been covered up, but also that some changes have taken place in this world.

What exactly those changes are, it's hard to say.

It's like how many years this North Sea has existed, why it has been so cold.

It may take extreme strength to find the truth.

Of course, this may also be the case when you have to go to the other side and find the past 10,000 years ago to know.

There may even be predecessors who have lived for 10,000 years and left this world.

In the mouths of those people, there will be things that Gu Meng wants to know.

Bai Yuchen didn't turn his head, nor did he answer Gu Ming's question immediately, the two of them just kept walking, and finally came to the end of the plain.

This is where you can go to the sea.

On the blue sea, there are countless ice cubes floating, and there are several icebergs faintly visible in the distance, in fact, most places in the North Sea are similar.

Standing on the seashore, Bai Yuchen said: "Why is the North Sea so cold? Naturally, there is a reason, and this reason is at the bottom of the sea, if you are lucky, you will know something." ”

After saying this, he didn't ask anything more.

There is no danger at the bottom of the sea, except for the cold, there is only cold left, if Gu Meng can withstand the cold, then there is nothing else.

"Don't stay at the bottom of the sea for too long, even if you don't think it's anything at the time, they will slowly invade your meridians and be troublesome to get rid of later. ”

At the beginning, Bai Yuchen had personally gone to the bottom of the sea, and he knew the most about the bottom of the sea.

After saying this, as soon as he raised his hand, Gu Ming's wrist was also raised, and a white light flashed, and Gu Luo felt that the connection between himself and Liu Yi was cut off.

Gu Meng glanced at Bai Yuchen.

"If there is any danger, overcome it yourself. ”

Bai Yuchen was a little indifferent, and even more ruthless.

Then he wanted to turn around and leave, but before leaving, he still asked, "All those jade algae pills have been eaten?"

Although Gu Meng didn't remember what he did after his "death" Liu Yi, he used other methods and read that paragraph, so he knew about stuffing those jade algae pills into his mouth.

To be honest, it was a bit of a waste to eat so much tamamodan.

Bai Yuchen glanced at him and didn't say anything.

In the end, he turned around and left, leaving Gu Meng alone.

Gu Luo glanced at his wrist, and actually understood why Bai Yuchen cut off the ribbon on his wrist before, which meant to tell him that he could leave on his own after that, and he didn't have to say goodbye to him again.

As for the ...... to Liuyi When it was cut open, it was already a farewell.

Gu Meng smiled, didn't think about anything more, just opened his hands, and then jumped into the North Sea.

Only a few waves are stirred up.

Maybe Gu Meng still has a talent for diving......

......

......

Cold.

Bitter cold.

The first time Gu Meng felt was the cold.

Those icy sea waters enveloped him in an instant, and at this moment, Gu Meng was still only a few feet away from the sea, and he already felt the biting chill.

He had to use Bai Yinjue, forming a red body protection qi around him, so that he felt much better.

After the cultivator cultivates, the cold and heat will not invade, but the cold at the bottom of the sea makes Gu Luo, a strong cultivator in the Flying Light Realm, feel cold.

As you get closer to the bottom of the sea, the chill does get heavier.

I don't know how long it took, maybe half an hour, maybe an hour, Gu Meng finally fell to the bottom of the sea.

His surroundings had turned a dark blue, much darker than the sun on the sea, and he looked down at the bottom of the sea beneath his feet, which was not dirt, but ice.

It's dark blue ice.

Gu Luo didn't seem to have come to the bottom of the sea, but to another Beihai ......

"This bottom of the sea, it's not bad. ”

Gu Meng muttered.

"Except it's a little cold...... Gu Meng muttered a sentence to add.

The light here was dim, and it was all blue, which made Gu Meng very unaccustomed, and he quickly took out the candle tour, which emitted a cyan light, dispelling some of the dark blue.

Candle Tour is now in its original form, just a cyan bead, which hangs by Gu Ming's side, illuminating the front for Gu Ming.

Walking slowly towards a certain place at the bottom of the sea, that is where the cold iron ore pointed out by Bai Yuchen is located.

The last time the Yuzao Sect mined this cold iron ore was many years ago, because there have not been many cultivators, and even the ones that were mined at the beginning have not been used up.

The cold iron under the sea, in fact, has not been much demand for the Yuzao Sect, although this sect has always been one of the top sects in the world, but whether it is the number of people or the demand for cultivation, there are not many.

In fact, most of the reason why the Yuzao Sect was able to become the top sect in the world was because of the possession of Bai Yuchen.

There is one of the Lord of the Four Seas, plus he is outside the continent and almost does not get involved in the affairs of the continent, and there is no reason for the cultivation world to go to Bai Yuchen's troubles, and those big sects with profound backgrounds almost all know some secrets, and they may also have some agreement on the existence of the Lord of the Four Seas.

After all, the Lord of the Four Seas will not defend the Four Seas for the mainland in vain, and he will also be embarrassed by the cultivation world.

Walking towards the established route, Gu Meng saw many scenes on the road that he had never seen before, there were many tall icebergs, the part that exposed the sea was tall enough, but this part of the sea was even more spectacular.

The bottom of the sea is like a complete world, and the only difference between it and the world on the surface of the sea is that it is soaked in seawater.

Perhaps many years ago, when there was no sea water in the North Sea, it was also a magnificent world.

Bypassing an iceberg, Gu Luo walked slowly in the sea, and along the way, he only felt a chill, and the rest did not even feel any vitality.

Gu Meng felt that the biggest shortcoming of Beihai was that it was lifeless.

After bypassing the two snow-capped mountains, Gu Meng was able to clearly see the road in front of him that had been carved out by manpower this time.

At the end of the road, something looms.

Gu Meng rubbed his hands, and then playfully took out the two fire-seeking beasts and put them in the palm of his hand, the two little guys curled up in a ball, trembling in Gu Ming's palm, and the two little guys looked at Gu Meng with a pitiful face, pitiful.

These two little guys are originally close to those masculine and rigid things, but they are the most disgusted with cold.

Letting the two of them out was originally Gu Ming's bad taste.

Seeing that these two little guys were pitiful, Gu Meng was embarrassed to do anything to him anymore.

After putting away the two little guys, Gu Meng hurriedly walked towards this road.

The scenery in front was no different, Gu Meng slowly moved forward, and then it didn't take long for him to come to the end of that road.

Gu Meng stood in place and looked up.

It was a mountain.

It's a very wide, tall mountain.

This mountain is snow-white, and it looks no different from ordinary snow-capped mountains, but if you look closely, you can find that the main body of this mountain is not ice and snow.

It's cold iron.

This is a cold iron mountain!

Gu Luo saw that in front of him, there was a pit on the wall of this Cold Iron Mountain, which was where the Yuzao Sect mined before.

It's just that what they mined is really not worth mentioning compared to the entire Cold Iron Mountain.

Gu Meng came to the front of the mountain, stroking the cold iron, his eyes were full of light, and there were thousands of materials used by the cultivation world to build magic weapons.

But cold iron is undoubtedly an excellent material for forging swords, and all the sword sects in the world want to have such a cold iron mine in their sects.

But this thing must be produced in extremely cold places, except for the North Sea, the rest of the world, there are only a handful of places with this cold iron ore, and not only are they few, but even the quality is not as good as those on the bottom of the North Sea.

Gu Meng jumped lightly and swam towards the top of the mountain.

When he finally came to the top of the mountain, Gu Luo was completely stunned for the next moment.

Standing on the top of the mountain, as far as the eye can see, there are still a lot of cold iron mines in front of it!

According to this amount, I am afraid that Zheshan will use it for tens of millions of years, and it is not a problem!

I didn't mention the mining time with Bai Yuchen before, thinking that according to Bai Yuchen's temperament, as long as he is still the lord of the North Sea, he will naturally not stop it, but when the time comes, Zheshan will definitely have to consider the idea of the Yuzao Sect more.

Looking at this piece of Cold Iron Mountain Mine, Gu Meng smiled and laughed, and his saliva almost flowed out.

Although he couldn't take it all away at this time, he seemed to have seen a mountain of gold, and suddenly became rich, no matter who it was, he had to jump up with joy.

Standing on the top of the mountain and looking into the distance, Gu Meng muttered, "What the hell am I ...... I'm not a poor bastard anymore!"

When he went down the mountain, Gu Meng thought about something a little happy, after taking over the mess of Zheshan, although there were a lot of disciples on the mountain, so that Zheshan had a lot of vitality, but those so-called vitality is not something that can be maintained for no reason, it is like a fire, you have it, but if you want not to extinguish it, you need to constantly put wood in it, in this cultivation world, what is wood?

It can only be money.

With countless expenses, it is really not easy to support a sect.

When Gu Meng first became the head of the sect, he was poor and white, there were so many people on the mountain, and he had to find a way, but now it's okay, this time there are so many cold irons, if he changes all these things to jade crystals, it is estimated that Zheshan is the richest sect in the world.

"Hey...... Get rich!"

Walking down the Cold Iron Mountain Mine, Gu Meng continued to walk forward, he wandered around in this piece of Cold Iron Mine, and encountered some large pieces of iron ore scattered down, he did not hesitate to put them away, so big that he couldn't take them away for the time being, these small ones, he didn't have any problem.

After all, he has the sharpest sword qi in this realm, and it is not difficult to use it to kill people, let alone use it to cut these cold irons.

When he returned to Zheshan, Biaozi jumped up with joy. ”

The longer he stayed at the bottom of the sea, the longer Gu Meng felt a cold current surging in his body, but fortunately, he still had the lotus flower and the sword tree in his body.

They are also slowly getting rid of all those chills, and Gu Meng is in excellent condition now, even he can feel it.

Standing on the last cold iron mine, Gu Meng looked up again, and there was no faint blue light in the distance, but it was pitch black.

What is that place?

Gu Meng remembered what he said to Bai Yuchen before going to the bottom of the sea.

Immediately, I was full of curiosity about more far-reaching places.

What is the cause of the cold in the North Sea?

What was the situation in this world 10,000 years ago?

Gu Meng thought about these things, and involuntarily walked farther away, he walked all the way, thinking about these things.

I don't know how long it took, Gu Meng came back to his senses, only to find that there was already darkness in front of him.

Even the light of the candle beads could not illuminate the surrounding environment, and Gu Luo could only see about a foot in front of him.

He took a few steps ahead and had to stop.

A black abyss appeared in front of my eyes.

That abyss, at a glance, gives people an extremely depressing feeling.

It's like an abyss to hell, and it's possible that demons may even be inhabited by it.

"Why...... No seawater?"

Gu Luo looked at this abyss with some incredulity, not only because of the oppression of this abyss, but also because he found that these seawater did not pour into this abyss, but hung on the surface of the abyss.

It was as if something had cut off the place from flowing into it.

Gu Meng squatted down, put his palm in front of the abyss, felt the chill in this abyss that was more piercing than the bottom of the sea, and muttered, "Could it be that this is the source of the cold in the North Sea?"
