Eternal Martial Emperor

Lin Yun had already said that he had a way, and Lan Fengyuan didn't have any taboos, just killing each enemy.

With Lan Fengyuan's participation, the underground army, which had only a few thousand people, could no longer resist.

In a short period of time, nearly five thousand underground people have died under Lan Fengyuan's sword.

And Lin Yun did not choose to kill this Martial Saint-level underground man, but directly released the "Wind Prisoner", tied its limbs, and controlled it.

After a period of time, this underground army has been completely wiped out by Lin Yun and others, and only this underground person with martial sage strength remains.

This underground man was now controlled by the "wind prisoner" and fell to the ground, unable to move at all.

Lan Fengyuan and the others also surrounded him. Only now is there a leisurely sentiment, and he can observe this underground man earnestly.

Through the transparent skin, everyone can clearly see the body structure of people underground, just like human beings, without any difference at all.

"You despicable ground humans... I won't let you die..."

This Wusheng-level underground man is not willing to give in. Although his limbs are controlled, he wants to try to blew himself up.

However, at this moment, Lin Yun raised his right hand and directly pressed it on his head, forcibly pouring divine consciousness into his mind.

The powerful spiritual power instantly made this Martial Saint-level underground man in a trance, unable to control his body.

At the same time, the memories in the minds of the underground people, one after another like three-dimensional pictures, appeared before Lin Yun's eyes.

Looking at the memory of this underground man, Lin Yun's expression gradually became surprised.

After roughly understanding the memory, Lan Fengyuan and others couldn't wait.

Lin Yun then told everyone about the source of the underground world he saw in the memory of the underground people.

It turns out that the source of the underground people, as Lin Yun had expected, is another kind of human!

Millions of years ago, underground people lived on the ground just like humans, and came from the same ancestors.

However, later on, because of the disagreement between the underground people and human beings, wars often broke out.

Finally, in a great battle millions of years ago, the underground people were defeated by humans and suffered heavy losses.

In order to be able to protect future generations, the underground people had to choose to escape to the underground world, and built a world here that belonged to the underground people.

"Because the immortal energy of the underground world is thin, they can only rely on the energy of the earth core to improve their cultivation and strength." When Lin Yun said this, everyone understood, and Lin Yun's next explanation, It makes everyone feel very strange.

According to Lin Yun, this group of underground people will turn into dust after death because they are relying on the earth's core energy exuded from deeper underground as the source of life.

After death, their corpses will also be turned into energy, which penetrates into the ground again, maintaining a balance of the energy of the earth's core.

Over the past million years, underground people have fully adapted to life underground, rarely stepping on the ground.

And, because they have lived in the ground for a long time, they can only absorb the energy of the Earth's core to improve their cultivation.

The underground people had no choice but to compromise and built their huge empire in the underground world.

Judging from the memories of underground people, the area of ​​this underground world is almost equivalent to half of the western continent.

Moreover, the system of the underground world is opposite to that of human beings. For example, among humans, the higher the status, the higher the place they live.

In the underground world, the higher the status of the underground people, the closer to the core of the earth.

The loess desert where they are now can be said to be just the tip of the iceberg of the underground world. If they go deeper, there will be a broader world.

"There are many such underground people in this underground world, and there must be many strong ones?" Lan Fengyuan showed a greedy look. Now this interesting species can be said to be a new human. If they can find a way to master the earth's nuclear energy, Lan Fengyuan can use this method to build his own super army.

However, what Lin Yun said next really surprised everyone.

"The population of the underground people has reached billions, and in the underground world, there is another one called the "underground king," who is the leader of all underground people. It seems that he has reached the realm of a half-step martial emperor. "

Billions of people?

Everyone couldn't help taking a breath.

What a concept this is!

What's more, there is a half-step Wudi among them!

They also came here by accident in the underground world, and their primary purpose was naturally to catch the earth spirit beasts.

But now it seems that after the earth spirit beasts disappeared, what they came to was the underground world, which might have some origins with the underground world.

If the earth spirit beast is protected by the underground world, then with the four of them, there is definitely no way to take it away.

Everyone fell silent. They needed to consider the pros and cons. A half-step Martial Emperor was sitting in town. This was not a joke.

"Among the billions of underground people, not many can actually participate in the war." Lin Yun continued: "Because of the long-term effects of nuclear radiation, the life span of these underground people is actually not long."

"You have also felt that although it is under the earth's crust, it still contains a very thin fairy qi."

"In the subterranean world, only the subterranean people who have almost reached the realm of Wuzun can absorb a little bit of immortal energy and breath of life to increase their lifespan."

"But even so, the life expectancy of underground people is generally not long."

Having said that, Lan Fengyuan was confused and asked: "If this is the case, how can they maintain a population of billions in millions of years?"

The dragon and phoenix beast on the side suddenly spoke, "I understand, it's an earth spirit beast."

Lin Yun nodded and explained: "Yes, it is the earth spirit beast. In the memory of this underground man, there are also earth spirit beasts."

In fact, the underground people didn't know much about the earth spirits and beasts, and they had heard other underground people talk about it.

It is said that a hundred years ago, a human-earth beast that had been extinct in ancient times broke into the underground world dying.

But the underground people in the underground world are very panicked and want to kill the humans and beasts to prevent it from revealing the secrets of the underground world.

However, this special monster race seemed to have attracted the attention of the Underworld King.

Not only did the underground king not kill this human-earth beast, but on the contrary, he rescued it, and used the earth's core energy to transform its body, and also gifted the human-earth beast with an earth element nuclear crystal.
