This time both the "Tomb" and the "Devil's Bureau" were eyeing Lin Yun, but Lin Yun and others did not notice these. They are now going deep into the ground, along the intricately distributed channels that are vertically and horizontally underground, and continue to look at them. The lower level of the underground world is advancing.

"It's weird...These passages are obviously artificially reinforced, why are they so deep?" Lan Fengyuan looked surprised, because they had now reached tens of thousands of meters underground.

In the beginning, it was necessary for them all to work together to dig tunnels, but gradually, they discovered that some tunnels were built here.

Moreover, these tunnels are obviously reinforced, this is definitely not from the handwriting of monsters, but more like human beings.

Lin Yun and Dragon Phoenix Beast glanced at each other. After all, whether the headquarters of God Tussong was in the assassination club, the headquarters of the Dark Gate, or the headquarters of Daughters Island now, they were all built in the underground world.

Could there be any power, like God Slaughter Sect, who chose to go deep into the underground world and build a headquarters in order to avoid some big figures and powerful forces?

"It's almost 50,000 meters deep." Lin Yun replied in a deep voice, his face also a little dignified.

Now they are about to reach the bottom of the earth's crust, and even the previous headquarters of the Tu Shenzong have not been built so deep.

If there is a real power to build the headquarters here, it will definitely not be a simple power, and it is even possible that it is a power that has not been discovered in God's Domain today, such as a hidden power like the "Tomb".

"Sect Master, there is light ahead." The dragon and phoenix beast flew in the forefront, and now stopped and said to everyone.

When these words came out, everyone looked at each other. Could it be that there really is another world in the ground?

"go!"

Under Lin Yun's leadership, everyone flew forward one after another.

The remaining passages are not long. After flying down for a distance of about several kilometers, the passage in front of them is getting bigger and bigger. In the end, an empty world suddenly appeared in front of Lin Yun and the others.

"here is……"

When they saw the world in front of them, Lin Yun and the four of them all showed surprised expressions.

They saw the endless yellow sand, a world like a desert.

Except for the Dragon Phoenix Beast, the few people present have all been to the "Sura Realm."

Unlike the "Sura Realm", this world does not have any strange laws, and even the circulation of immortal energy is no different from that of God's Domain, except that the concentration of its immortal energy is much lower than that of God's Domain.

This desert world looks ordinary, even a little ordinary, and it can be said to be exactly the same as the desert zone in the world of God's Domain, without any difference.

Looking at the endless yellow sand surrounding them, Lin Yun and others looked very small in front of this natural style.

Everyone was looking around the environment, and soon they discovered that there were countless strange objects hanging above this world.

The objects are like little suns, emitting extremely strong light, illuminating almost the entire world.

"No... this is not a small world, but belongs to the realm of God." Lan Fengyuan frowned. He looked at the sky and could clearly see that there was obviously a layer of rock at a height of 10,000 meters. .

This also means that the passage they passed through was not a transmission passage, but a real one, leading to the underground world.

This underground world is located in the realm of God, not a small world created by man, like the "Sura Realm" or "Earth Village".

"This place is very big, even bigger than the entire chaos domain." Lin Yun opened his eyes. He just released his divine sense and explored the surrounding environment, and found that his divine sense can spread over thousands of miles, still Unable to explore the entire world.

"Also remind you that there are other creatures here. As for what they are, I don't know." Lin Yun reminded in a deep voice.

Just after he released his divine consciousness, he sensed a lot of life aura, but at a long distance, he could not clearly detect the appearance of these life forms, and he could only be sure that it was not a human being.

"Lin Yun, the thing that glows in the sky seems to be a stone..." the dragon and phoenix beast fell from the sky and said to Lin Yun.

"It may be the legendary "Earth Core Sun Stone." Lin Yun frowned slightly, replied.

"Earth Core Sunstone?"

This unfamiliar vocabulary has never been heard by Lan Fengyuan, Doctor of Biology, or Dragon Phoenix Beast.

"In ancient times, there were some rumors that there was an underground world under the ground of God's Domain." Lin Yun explained: "The underground world has no sunlight, but there is a kind of ore that absorbs the energy of the earth's core, called "Earth Core Yang". stone". "

The "Earth Core Sun Stone" not only provides light, but its light also contains heat. "

"If I remember correctly, these hanging rocks should be "earth-core sunstones." "

After listening to Lin Yun's words, everyone suddenly realized.

And Lan Fengyuan also moved his mind, smiled, looked at the "Earth Core Sun Stone", and asked: "Then this kind of ore is very valuable and contains the energy of the earth's core. If it can be used, Among all the energy ores, it is also one of the best."

There is no doubt that an ore can absorb the nuclear energy, and its value is self-evident.

But Lin Yun's next words directly extinguished Lan Fengyuan's thoughts.

"Don't think too much, this kind of "earth core sun stone" needs to absorb the energy of the earth core all the time. Lin Yun pointed to the ground and said, "Although it is still far away from the earth's core, it can still maintain the operation of the "Earth Core Sun Stone" a little bit. "

"If you take it off without bringing it back to the ground, it will already be turned into a mass of ashes."

"It's a pity." Lan Fengyuan sighed, then looked around and said: "Then it's all yellow sand now, it looks the same, where should I go?"

The dragon and phoenix beast slightly mimicked his eyes, as if he was sensing something, and Lin Yun had already raised his head, looked in one of the directions, and said: "About a thousand miles ahead, there is a very strong breath of life, you can go and take a look."

A group of four people didn't make more stops, so they flew at extreme speed and flew in the direction Lin Yun said.

Although Lin Yun and Lan Fengyuan are both very fast, in order to take care of Dr. Biology and Dragon Phoenix Beast, they both deliberately slowed down. After all, if this world is unknown to them, if they encounter any danger, then Going too far is not easy to help.

And as it gradually penetrated into the depths of this world, everyone discovered that this world really has creatures living here.

When they flew to Baili, there was already a ruin in front of them.
