Although this underground space has a total of four layers, the first three layers are where the demons reside.
However, this third layer can actually be strictly divided into two smaller layers.
The upper layer houses more powerful demons, Divine Kings or Divine-level demons.
The lower layer, closer to the earth's core, is home to even more powerful demons.
For instance, those two Divine Lords.
Currently, all the demons in the upper part of the third layer have awakened and are clamoring to kill the humans who have intruded into their lair.
These demons initially gained energy by devouring other living beings, but after a period of time, all the living beings in this world were killed.
With no other living beings left, the demons began to devour each other.
Much like big fish eating small fish, they slowly enhanced their strength by devouring their own kind.
The demons capable of reaching the third layer have all gone through thousands of battles before arriving here.
Compared to the demons on the upper two layers, they are more ferocious and terrifying, filled with evil power.
The vast majority already possess abilities beyond Divine level or Divine King.
Their defense and attack power are not to be underestimated.
Therefore, when these powerful demons move, the scene is incredibly shocking.
Currently, most of the territorial lords and rangers have entered the underground world.
They are fighting the demons on the upper two layers, completely unaware that their arrival has caused other changes deep underground.
A group of powerful demons have awakened and are preparing to attack them.
The entire underground world has now descended into chaos, but the surface remains as normal.
The territorial lords and rangers are desperately killing demons.
"Kill! These are all my experience points!"
"As long as I kill all these demons, I'll be just one step away from Divine level."
"Brother, that's not good enough for you. I only need to kill seven or eight more, and I'll reach Divine level. I'll be ahead of you then!"
"Let's not talk about these useless things. Haven't you noticed that the demons seem a bit more ferocious than before?"
"Huh? Is that so?"
In reality, the demons on the upper two layers, because the demons on the third layer began to stir, brought forth more demonic energy, which dispersed some of the fatigue caused by the appearance of the sun.
However, most of the territorial lords and rangers were too engrossed and enjoying themselves, completely failing to notice this subtle change.
Yet, some people could sense it.
"Yes, why do these demons feel harder to kill now? This shouldn't be the case. It's still daytime, so why is the change so significant?"
After hearing this, everyone finally felt that it seemed to be true.
It is clearly daytime, when demons should be at their most vulnerable, yet now they are slowly becoming more ferocious.
They are actually harder to kill than at night. What could be the reason?
A sense of unease began to creep into some minds, "Could something we don't know about have happened?"
Most of the territorial lords and rangers still didn't take these changes seriously, remaining carefree.
"Why bother with so much? We just kill!"
"Exactly, as long as we get the experience, we're profiting!"
At this moment, Xiao Mo's immortal and demon army was also continuously killing demons.
Their method of killing demons was completely different from those territorial lords and rangers who formed small teams.
The immortal and demon army was like bulldozers, slaughtering the demons and clearing the way.
In a short time, they were approaching the second layer.
Just then, Xian'er twitched her nose and said:
"Your Majesty, the demons on the third layer seem to have been alerted. They've all started moving."
Xiao Mo was not surprised, as the strong aura of humans entering the underground world would surely awaken those demons.
"Were the two Divine Lord level demons on the third layer also alerted?"
Xian'er shook her head. She said:
"It seems that the Divine Lord level demons on the third layer and the Divine Lord on the fourth layer are in a tense moment."
"Therefore, the Divine Lord level demons on the third layer have not made any significant moves."
Xiao Mo raised an eyebrow and said meaningfully:
"It seems that no matter whether the Divine Lord on the fourth layer is willing to cooperate with us or not, he will have to cooperate with us!"
This is because the Divine Lord level demons on the third layer are coveting the world laws of the fourth layer.
Once they break through the barrier to the fourth layer, they will definitely kill that Divine Lord!
Therefore, it has now come to a critical juncture, where one wrong step means falling into the abyss.
The Divine Lord on the fourth layer must also be under immense pressure.
As long as they extend an olive branch, if the Divine Lord on the fourth layer has any sense, he will definitely agree to their plan.
Now, their most important task is to deal with the rioting demons on the third layer.
Xiao Mo's face turned cold, and he issued another order.
"All troops, assemble and advance to the third layer. Immortal and demon troops at Divine level and above will serve as vanguards, with the rest following behind!"
"The upcoming war may be a bit arduous, but we must succeed, and we cannot fail!"
"Yes! My Lord!"
As soon as his voice fell, a response that shook the heavens and earth followed.
Instantly, the immortal and demon army began to move, organizing their ranks with high morale and heading towards the third layer.
With the disturbance from the upper part of the third layer, the entire underground world once again descended into chaos.
On the lower part of the third layer, lived two Divine Lord level demons.
They had already taken on complete human forms, and except for two black horns on their heads, they were indistinguishable from humans.
A Divine Lord demon wearing a skull necklace opened his eyes and said coldly:
"Someone has entered the underground world!"
Another Divine Lord demon, dressed in a black robe, replied with his eyes closed:
"Indeed."
His voice was very soft, surprisingly that of a young girl!
The female Divine Lord demon's lips curved into a cold sneer, and she said carelessly:
"It seems the world laws haven't given up struggling, actually bringing in so many humans!"
"Hmph! It's all in vain!"
This female Divine Lord demon actually revealed how these territorial lords and rangers had entered with just one statement.
It was as if she had known it all along.
The other male Divine Lord demon with the skull, however, retorted:
"Impossible. Although the world laws are guarded by that bitch Morina, she couldn't have brought in other humans."
"Oh?"
The female Divine Lord demon's face also showed some confusion, "Then if it wasn't the world laws causing trouble, how did these humans get in?"
