Zhou Ming followed Mao Zhen towards the passage to the north.

"This passage to the north is no less dangerous than any other, so be careful, here I allow you to escape alone in case of danger!"

Mao Zhen suddenly said something that shocked everyone.

You must know that when encountering danger, everyone saves their lives, although this is a reality, but it is a thing that cannot be put on the table.

But I didn't expect Mao Zhen to say this.

A few people who knew the situation were silent, and obviously agreed with Mao Zhen's words, and even Lao Yao, who had been arrogant, stopped talking.

Zhou Ming also listened quietly, in fact, he had an impression of this, in his previous life, as an ordinary martial artist, he naturally couldn't save going deep into the ground to find resources.

Here he also remembered that he had been here, but he couldn't remember it clearly, it was all ordinary memories from thousands of years ago, where could he remember it clearly.

At that time, the ordinary danger was nothing surprising to him, after all, it belonged to the low-level martial artists.

When he really transformed into the spiritual realm, he got the first inheritance and a series of legacies, and since then, he has truly become a relatively powerful cultivator.

If he could, Zhou Ming would love to get that opportunity.

"It should be almost, I will be born in more than ten years!And in this life, I can get the inheritance of my mentor on the premise, and I can try to see it after the Spirit Gathering Realm!"

It was the inheritance of his mentor, although Zhou Ming had never seen the mentor who left the inheritance, but this did not affect his respect for his mentor.

Because of that inheritance, he has the opportunity to go further, so as to become a generation of strong people, this kindness is remembered by his previous generation, and he will not forget it in this life.

"Zhang Shan, why are you in a daze! Let's go!" Lao Yao shouted.

Zhou Ming came back to his senses, smiled, and then followed.

"Zhang Shan, you don't have to worry, although it is dangerous here, there is no need to be too afraid, the danger of killing people at every turn is not so often, most of them can still be avoided!" Lao Yao kindly reminded.

"I know!" Zhou Ming responded with a smile.

"That's right!" Lao Yao patted Zhou Ming's back fiercely, this thick arm, ordinary martial artists are afraid that they can be directly slapped to death by him.

Follow Lao Yao, Zhou Ming

Catch up with the group and walk forward together.

The appearance of the Northern Pass is similar to that of the west, and it looks like a huge canyon, with high mountains on both sides, and only a relatively narrow gap in between.

Of course, this narrowness is also compared to the mountains on the left and right, in fact, this passage is not narrow at all, it is ten zhang wide.

It's just that this passage is a little less than the mountains on both sides, and the two mountains, or the height of the two mountain ranges, are no less than a thousand feet.

"Everyone, be careful, there is actually earth fire down here, but the rocks here are more special, and the ground fire is not easy to erode, but a small number of places are still easy to step on!"

I'm afraid that the result of stepping on the air will be half the life, and the rocks here are extremely special, and the warrior may not be able to come out after falling.

It's easy to fall into such a small hole, but it's not so easy to figure it out, not to mention that there is a fire underneath, and the temperature is extremely high.

"It's really strange here!" sighed again.

"Yes, this sea is full of earth fire, and there are actually eight mountain ranges above the earth fire, and two by two form a passage!"

If earth fire is equivalent to water, then there are mountains hundreds of miles long and thousands of feet high above the sea.

How is this possible!

And the facts are in front of you, and there is really a strange scene of mountains floating on the earth and fire.

"I heard that this place is not natural!, but it was specially opened up by a strong person!" Zhou Ming said suddenly.

Hearing Zhou Ming's words, everyone's eyes were focused on him.

Looking at the eyes of many inquiries, Zhou Ming also heard the news in his previous life.

In his previous life, he often went in and out of the ground, and he didn't leave until he turned into a spirit realm, and for more than ten years before and after, he was naturally not comparable to this group of people in terms of news.

"I heard that this was once a forging ground for a strong man!" Zhou Ming said.

"The forge is used to forge treasures?"

Zhou Ming shook his head: "Of course not, how could such an existence need to forge a treasure weapon, even a higher-grade spiritual weapon would not be taken into account by them!"

This is true, but it is a bit old, I am afraid that it goes back to the primeval times more than 100,000 years ago.

At that time, the primeval creatures were all huge, and the place where they forged was self-sufficient

However, it is not ordinary.

"This is actually a forge yard? this is the earth sea, such a big place!" exclaimed Lao Yao.

This is really beyond his imagination, just look at Fang Yuan to understand, this sea spans no less than thousands of miles, how big is this area?

The islands in the middle of the sea alone are hundreds of miles in circumference.

"Zhang Shan, you are boasting big! How can you forge in such a big place?"

"Yes, this legend is completely untrue!"

Countless people shook their heads, feeling that what Zhou Ming said was just a false legend and could not be trusted.

Zhou Ming said with a smile: "This is all true! And you have seen that you are wrong, the original scale of the Earth Sea is ten times larger than it is now!"

"It can't be!"

"It's fake!"

Someone immediately retorted, the current earth sea is so big, the original earth sea is actually ten times larger than now?

"That's right! The original earth sea is indeed ten times larger than it is now, and the earth fire is not a deep earth fire, but a fire in the center of the earth!" Zhou Ming said word by word.

"The more you talk about it, the more mysterious it becomes!" said Lao Yao shook his head. "Zhang Shan, who are you listening to, in the center of the earth, it is something that the Spirit Transformation Realm, and even the Soul Fusion Realm martial artists have to detour!"

"Yes, but this is the basic material forged by the strong!" Zhou Ming continued. "This sea is actually the forging ground of the powerful of the primeval era. At that time, the earth was not as thick as it is now, and this was the location of the center of the earth at that time, and such a large open place under the ground was not natural, it was also opened up by primeval beings!"

When it comes to the vast underground environment, everyone is no longer refuting.

It's all underground, and theoretically it's all rocky and dirty, but there's such a big space.

This is absolutely unreasonable, there are thousands or even tens of thousands of zhang thick earth above, and even so, it has not been able to crush this space.

To say that this is a natural occurrence, no one can do it.

"Are primeval creatures really that powerful, can they hollow out the entire underground?"

Zhou Ming nodded: "The primeval creatures are indeed very strong, but it doesn't matter, they have all been wiped out by us humans, and now this world is the treasure land of our human race! The primeval creatures have become a thing of the past, and human beings have multiplied here for tens of thousands of years, how can there be any primeval creatures!"
