This is a vast grotto, with powerful lighting fixtures installed everywhere, illuminating the world before us in a dazzling display.

Shen Qian was standing on a stone platform inscribed with a teleportation array. Around him, there were countless similar stone platforms, stretching all the way to the end of his field of vision.

In front of the stone platform, there is another arched bridge that extends deep into the grotto.

Deep within the grottoes, countless buildings and pavilions can be vaguely seen standing tall, with wisps of colorful mist swirling in the air, rendering the area where those buildings are located as dreamlike and ethereal.

All around, as the space fluctuated, figures would appear on the stone platform, chatting and laughing as they walked forward, crossing the arched bridge and disappearing into this vast grotto world.

Some people come in a hurry, arrive at different stone platforms, and then disappear from this world.

Shen Qian glanced at the Mountain and Sea Badge in his hand and couldn't help but be surprised.

This badge was actually a sub-symbol of a teleportation array.

In other words, the sinking was not a teleportation of consciousness, but rather the physical body directly arriving in this world called "the Earth's core".

While he was still in a daze, a strong spatial fluctuation flashed by beside him, and then Zheng Lei and Dao Jiu appeared beside him one after the other.

"Where... exactly is this place?"

Upon seeing the two appear, Shen Qian could no longer contain his curiosity and asked.

"Since this space is called the Earth's Core, Major Shen, why don't you guess where this is?"

Zheng Lei laughed.

"The Earth's core..."

A thought struck Shen Qian, as if he had just realized something. His spiritual power began to extend upwards, quickly penetrating the dome of the grotto and continuing upwards.

Ten meters, one hundred meters, one thousand meters...

With his current mental strength, Shen Qian could spread his power to several thousand meters away, but all he could see were thick soil and rocks, as well as various metal elements, seemingly without end.

Soon, Shen Qian, who had quickly withdrawn his mental energy, exclaimed in surprise, "Is this the core of the Earth?"

Seeing Zheng Lei nod, Shen Qian was even more shocked.

He never imagined that this "center of the earth" would actually be the physical center of the earth.

"Why is it different from what's written in the textbook again?" Shen Qian touched his nose, somewhat speechless.

According to physics textbooks, the Earth's core should be a completely solid state. Of course, there are many different opinions in online posts, but no one has ever mentioned that there is such a strange space at the deepest part of the Earth.

"The Earth's core is accessible only through mountains and seas. Due to the principle of secrecy, ordinary martial artists naturally do not know about such a place," Zheng Lei said with a smile.

He nodded, and his mood quickly calmed down.

He's gotten used to it.

It's his own fault, really. He rose too quickly in martial arts, whereas ordinary martial artists progressed step by step and could gradually adapt to the changes in their worldview brought about by upward mobility.

Before sinking... there really wasn't the time to slowly accept all of this.

Who would have thought that just over six months ago, he wasn't even a beginner martial artist?

But now that he has entered the River of Time, which 99% of people have never even heard of, he really shouldn't be making such a fuss.

Why does such a place exist?

Shen Qian asked the core question.

"We can talk as we go. How about I take Major Shen inside to have a look first?"

Zheng Lei reached out his hand.

Zheng Lei immediately led the way, and the three of them crossed the arched bridge together, heading deeper into the grotto.

After crossing the arched bridge that stretched for miles, the buildings that had been vaguely visible before began to gradually become clearer.

When you reach the end of the arched bridge and stand in mid-air, the visual impact is once again awe-inspiring.

What appeared before them was a vast, boundless metropolis.

There are skyscrapers reaching hundreds of meters high, as well as ancient-style pavilions; there are wide streets stretching hundreds of meters, as well as verdant mountains and azure lakes...

The most incredible thing is that, before sinking, one could clearly see a pyramid that was clearly only found in Egypt, standing thousands of meters away.

Those completely different architectural styles and landscapes, combined in a strange way, have become the vast metropolis that I see in my current vision.

This city is even more prosperous than Beijing and Shanghai.

People come and go on the street, hurrying along, while figures walk through the air and pass each other in mid-air.

But what shocked Shen Qian the most was that the aura of most of the figures moving through them was as deep as the sea.

A powerful figure from the mountains and seas!

Over 80% of those who come into view are genuine experts from the Mountain and Sea Realms.

How can there be so many powerful experts from the Mountain and Sea realms? And what gives them the right to be so many powerful experts from the Mountain and Sea realms?

To give an imperfect example, even if we include the special location of the Tower of Babel in Jingcheng, which ranks among the top three in terms of town size in the first province of Southwest China, there would be no more than ten martial artists from the Mountain and Sea realms in the entire city.

In cities like Xicheng and Tongcheng, even the city lords number only a handful of three to five.

But at this moment, just from what Shen Qian could see on the mountains and seas, there were at least several thousand people.

There's not even a need for mental perception, because there are already over a thousand figures walking through the air.

However, Shen Qian was only standing on the edge of the city at this moment, which meant that what he saw was actually just the tip of the iceberg.

If the entire city were like this, how many martial arts masters from the mountains and seas would there be?

"President Zheng..."

"When Major Shen activated the badge, he must have heard a number, which was actually a sequential arrangement."

As if he had already guessed Shen Qian's doubts, or perhaps everyone who sets foot in this mountain and sea for the first time would be so shocked, Zheng Lei spoke up as soon as Shen Qian opened his mouth.
