Lin Yun had already said that he had a way, so Lan Fengyuan didn't have any taboos and just killed the enemies one by one.
With the addition of Lan Fengyuan, the underground army with only a few thousand people was completely unable to resist.
In a short period of time, nearly five thousand underground people had died under Lan Fengyuan's sword.
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 was completely annihilated by Lin Yun and others, leaving only the underground people with the strength of the Martial Saint.
This underground man was now controlled by "Wind Prisoner" and fell to the ground, unable to move at all.
Lan Fengyuan and others also gathered around, and now they were free to observe this underground man carefully.
Through the transparent skin, everyone can clearly see that the body structure of the underground people is exactly the same as that of humans, with no difference at all.
"You despicable ground humans... I will not let you die..."
This martial saint-level underground man was not willing to give in. Although his limbs were controlled, he wanted to try to self-destruct.
However, at this moment, Lin Yun raised his right hand, pressed it directly on his head, and forced his consciousness into his mind.
The powerful mental power instantly made this martial saint-level underground man in a trance and unable to control his body.
At the same time, the memories in the underground people's minds also appeared in front of Lin Yun's eyes like three-dimensional pictures.
Looking at the memory of this underground man, Lin Yun's expression gradually became surprised.
After roughly understanding the memory, Lan Fengyuan and others were already a little impatient.
Lin Yun then told everyone about the origin of the underground world he saw in the memories of the underground people.
It turns out that the origin of this underground man is indeed another kind of human being as Lin Yun expected!
Millions of years ago, underground people lived on the ground just like humans and came from the same group of ancestors.
However, later, due to the differences in ideas between the underground people and humans, wars often broke out.
Finally, in a great war a million years ago, the underground people were defeated by humans and suffered heavy losses.
In order to protect future generations, the underground people had to choose to escape to the underground world, and built a world here that belonged entirely to the underground people.
"Because the immortal energy in the underground world is thin, they can only rely on the energy of the earth's core to improve their cultivation and strength." When Lin Yun said this, everyone understood, and Lin Yun's next explanation,
It made everyone feel extremely strange.
According to Lin Yun, the reason why this group of underground people will turn into dust after death is because they rely on the core energy seeping out of the deeper underground as the source of life.
After death, their corpses will turn into energy and seep back into the ground, maintaining a balance of energy in the earth's core.
Over the past million years, the underground people have completely adapted to life underground and rarely set foot on the surface.
Moreover, since they have lived underground 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 own huge empire in the underground world.
According to the memories of the underground people, the area of this underground world is almost equivalent to half of the western continent.
Moreover, the underground world is opposite to the human system. 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 they live 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 we continue to 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 among them, right?" Lan Fengyuan showed a greedy look. Now this interesting species can be said to be a new human race. If we can control them,
After finding a way to control the energy of the earth's core, 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 the underground people. He seems to have reached the level of a half-step Martial Emperor."
Billions of people?
Everyone couldn't help but take a breath of cold air.
What a concept!
What's more, there is a Half-Step Martial Emperor among them!
They came to the underground world by chance this time, and their primary purpose was naturally to capture the earth spirit beast.
But now it seems that after the earth spirit beast disappeared, it came to the underground world, and it may have some connection 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 sitting in charge was no joke.
"Among the billions of underground people, not many can actually participate in the war." Lin Yun continued: "Due to the long-term impact of the earth's nuclear radiation, the life span of this group of underground people is actually not long."
"You have also felt that although this place is under the earth's crust, it still contains very thin fairy energy."
"In the underground world, only the underground people who have almost reached the realm of martial masters can absorb a little immortal energy and life breath to enhance their lifespan."
"But even so, the lifespan of underground people is generally not long."
At this point, Lan Fengyuan became confused and asked: "If this is true, how could they maintain a population of billions in millions of years?"
The dragon and phoenix beast on the side suddenly spoke and said: "I understand, it is the earth spirit beast."
Lin Yun nodded and explained: "Yes, it is the earth spirit beast. This underground man also has something about the earth spirit beast in his memory."
In fact, this underground man himself didn't know much about the earth spirit beasts. He mostly heard other underground people talk about it.
It is said that a hundred years ago, a human-earth beast that had become extinct in ancient times broke into the underground world while dying.
But the underground people in the underground world are very panicked and want to kill the human-earth beast to prevent it from leaking the secrets of the underground world.
However, this special race of monsters seems to have attracted the attention of the Underground King.
Not only did the Underground King not kill the human-earth beast, but he revived it, used the energy of the earth's core to transform its body, and gave an earth element nuclear crystal to the human-earth beast.
