In the previous confrontation, if it weren't for Lu Zheng's boldness and carefulness, he might have been killed by the three giants of the Dao God Stage long ago.

At that time, the Eternal Thunder Pool had almost completely dried up, and the only bit of energy left, let alone against the giants, it was difficult to even kill another giant of the Yuan God Stage.

Fortunately, the three of Star Dou Ancestor were suppressed by Lu Zheng's mysterious identity from the beginning.

A person who was once an old friend of the Emperor of the Inviting Moon, and who had a close friendship with the Abyss Demon Lord, knew a lot of ancient secrets, and was very likely to be an invincible genius who was reborn from the strong.

This kind of character, even if it is a giant of the Dao God Period, does not dare to provoke easily.

Because you don't know how terrifying he was in his previous life, how many secrets of the heavens and worlds he knows, how many hole cards he has that can turn the situation around in an instant, and you don't know how many immortals-level people are behind him.

It is this sense of mystery that does not know the depth of Lu Zheng at all that causes the three Star Dou Ancestors to be afraid of him, even if Lu Zheng talks nonsense casually, most of them will believe it.

However, this short-lived peace is very fragile, like walking on a tightrope across a cliff, and at any moment there is a risk of falling into the abyss and breaking bones.

The current Lu Zheng's biggest reliance is this sky city, but he has not reached the realm of the Void Immortal, after all, it is difficult to exert its true power.

In Lu Zheng's hands, Sky City can only be used as a big toy that scares people at most, and even the Dao God Stage giants can't kill it.

Shout!

Lu Zheng's figure moved, and he entered the interior of Sky City again.

In the ancient city, huge stones are piled up, and the walls and streets are covered with sword marks and sword wounds, and everywhere exudes the vicissitudes of life, which has gone through countless years.

The city is very quiet, and it can be said that it is terrifyingly quiet.

The streets were empty, and the alleys and squares were equally empty.

All the houses were tightly closed, and the windows were completely locked.

The entire city in the sky exudes an air of dead silence, as if you are in a cemetery, empty and lifeless!

It's a dead city, a dead city in the truest sense of the word. Except for Lu Zheng, there is not a single living person here, or even any living creatures.

Ten thousand years ago, even the dignified Abyss Demon Lord had fallen, let alone the army under his command?

It is rumored that under the hands of the Abyss Demon Lord, there is a hellish army that sweeps through the heavens and all worlds, a million demon soldiers, any one of them is a giant of the Yuan God Period, and even the centurion inside is a giant of the Dao God Period.

As for the immortal cultivation realm, he is almost equivalent to a god-like void immortal, and in the abyss demon lord's million hell army, he can only serve as a general who leads ten thousand demons.

And the Void Immortal General like this, under the hands of the Abyss Demon Lord, even exceeded a hundred.

If the Eternal Thunder Pool is the power core of Sky City, then these million demon soldiers are the massive cogs that drive Sky City to operate.

Lu Zheng could neither store a huge amount of thunder energy for the Eternal Thunder Pool, which was the core of power, nor could he master the millions of demon soldiers sealed in the Sky City to activate the countless attack arrays of this immortal weapon.

"I don't know what happened to that little girl in the underworld?"

Lu Zheng smiled slightly, and suddenly remembered the little princess of the earth demon who was inadvertently subdued in the underground world.

After a long time, if it weren't for the recent calm and calm that gave Lu Zheng a lot of leisure time, maybe he would have forgotten about that little girl.

One step out, Lu Zheng's figure, in an instant, appeared thousands of miles away.

Having reached the realm of the early stage of the Yuan Shen, today's Lu Zheng, even if he does not tear the space and move the space, just by virtue of ordinary speed, it is instantaneous, exaggerated to the extreme.

In less than a quarter of an hour, Lu Zheng appeared in front of the huge underground crack again.

It's just that now, this deep and dark underground crack has long become ordinary in Lu Zheng's eyes, and there is no danger at all.

"After the deceased, I don't know how many of them are, where they are now, and what is the situation at this time?"

Lu Zheng smiled bitterly and shook his head, "They are still in the realm of the Nine Tribulations Void Immortal, instead of worrying about those old friends, it is better to worry about yourself first!"

Moving his footsteps, when the dim light appeared, Lu Zheng's figure had already stepped into the underground world of the desolate star.

Here, it is still dark and dark, and there is no light all year round.

If it weren't for the faint light of the fluorescent grass, which slightly illuminated the underground world, it is likely that the current earth demons are still blind, and their eyes cannot adapt to the light of the surface world at all, let alone threaten the human race and the demon race.

Such a land demon clan can only live in the dark underground world forever, exploited and squeezed by the strong men of the human demon race for life and life, and the massive resources contained in the underground world will be continuously sucked clean by them.

Because the strong people in the surface world can enter and leave the underground world at will, but the land demons in the underground world cannot adapt to the environment of the surface world.

When Lu Zheng brought out the seeds of fluorescent grass from the ancient ruins, the immature and lovely little girl was so excited that she danced and confessed to him in public, saying that when she grew up, she would be his bride.

How many years have passed, things are right and people are not, even if Lu Zheng meets that little girl again, I am afraid that he will be relatively speechless, and he is in a hurry.

Under the dark city, an army of millions of earth demons, a large area of black oppression, surrounded this ancient castle.

These earth demon armies, arranged in a neat and orderly manner, obeyed every word of the order, and a monstrous murderous aura soared up, showing a well-trained iron-blooded army.

Even from the perspective of individual soldiers, they are all wearing black iron armor that has been tempered for thousands of years, equipped with a unified standard of white scimitar at the waist, with strong bodies and full of spirit, and there is no doubt that they are all veterans of strength who have been on the battlefield for a long time.

The strength of such an army, on the barren star, is absolutely devastating and sweeping everything.

Even the Star Dou Academy, one of the four major academies, had to deal with it carefully when it encountered this army of earth demons, and did not dare to be sloppy in the slightest.

In front of the Earth Demon Army, a one-horned black dragon lion, with teeth and claws, fierce and powerful.

And on the back of this ancient xenomorph sat a young man in dazzling silver armor.

He looks handsome and incomparable, his eyes reveal a strange look, and his every move is full of elegance, like a talented man from a scholarly family.
