This is the Demon Realm.

The sky was gloomy, and among the dense and heavy black clouds, blue lightning snaked like long snakes, and the earth resounded with deafening thunder.

The atmosphere of this heaven and earth has been so gloomy since ancient times, and it has not changed for thousands of years.

At a glance, most of this continent is covered with mountains and forests, with tall and towering ancient trees, huge beasts, huge rocks, huge rivers, and mountains.

It's as if everything in the world is huge.

These seem to be creations of prehistoric antiquity, in the eastern part of the continent, divided by a silvery-white metallic line over a plain.

Bounded by this silver dividing line, one side is full of wild and beautiful natural scenery, and the other side is a cold and hard metal building.

This is the front line of the confrontation between humans and the demon spirit world, since a few years ago, the great hero of the human race, sacrificed himself, with the power of half a moon to inflict heavy damage on the entire demon spirit world, the demon spirit world has lost dozens of giant demons, and the human side has also taken advantage of the victory to pursue.

Finally, after entering the range of one-tenth of the territory of the demon realm, a defense line was built on this plain.

Behind this plain is the gate to the world to the earth, so it is also the first line of defense to protect the earth.

Here as far as the eye can see, in this thunderous sky, the wind blows, the verdant grassland forms the same image as the sea, layer after layer of green waves on the grassland undulating, magnificent and picturesque.

And at the silver-white line, when I looked closely, I found that this line was a tall metal Great Wall, and on top of this silver-white metal Great Wall, there was a humanoid machine.

These are the tens of thousands of grassroots mechanical troops used by the human beings on the earth to resist the demon spirit world, and each mechanical soldier is equipped with the latest psionic weapons developed by the earth, which is a combination of cultivation and science, which is called the crystallization of rune technology.

Although these mechanical soldiers can't effectively stop the powerful giant monsters, they still have no problem facing the demon beasts under the general strength.

The most important thing is that mechanical soldiers can be mass-produced, although the cost of this kind of mechanical soldiers is expensive, but in order to know the movements of the demon world for the first time, and to guard against the second attack of the demon world, the investment of these troops is very necessary.

In the past few years, although the large-scale attack of the demon spirit world has not appeared again, there is often a small group of demon beasts to attack the Great Wall, in general, over the years, small conflicts have been experienced on the Great Wall no less than a hundred times.

…………

It was a cold day, thunder rumbled, and soon a drizzle began to fall in the sky.

The rain hit the green grassland, and the whole plain was shrouded in a thin layer of white mist, full of a very beautiful artistic conception.

However, behind this beautiful artistic conception, the Great Wall is shrouded in a sense of slaughter that is about to come.

In a certain section of the Great Wall, there are several humans standing above the city wall, their faces are resolute, and they have fought against demon beasts many times over the years, and each of them has a weathered vicissitudes on their faces.

In front of these human beings, there was a heroic woman dressed in red, her hair was simply tied up with a red ribbon, and there was a hint of tiredness on her beautiful fair face, she stared at the sky, and there was a little longing in her eyes.

The wind and rain fell on the city wall and stirred in the grass, which naturally wet the clothes of these people, and their hair was wet on their foreheads, but they still did not dare to relax their eyes to look ahead, because this was their daily work.

Stick to the city wall and don't dare to relax for a moment.

The rain pooled down the steel bodies of the mechanical soldiers and fell down the walls, and then down the cold, hard steel walls.

Suddenly!

A cold electronic announcement came from a base tower near these people:

"Warning! Warn! Go to the five kilometers and find a small group of demon beasts, which are expected to arrive in ten minutes, and ask the soldiers and generals of the Tianzi 64th defense line to prepare for battle. ”

"Toot!" "Toot!" "Toot!"

Red sirens immediately flashed on the city walls, along with the shrill sound of horns.

In addition, the electronic broadcast system is issuing a series of instructions at the same time.

"The Lingzi laser pulse cannon will carry out the first wave of precision strikes in ten seconds, ten, nine, eight ......"

All the human beings, including the woman in red, looked solemn at the moment, and looked ahead, waiting for the ten seconds to count down to the last "one".

A tall tower on the city wall suddenly condensed a bright and blinding white light.

This brilliant light made it seem as if even the gloomy sky was illuminated.

Rumble!

The light took the shape of a parabola, and it fell far beyond the horizon, five kilometers away, and it was a shock that shook the mountain.

"Report the results of the battle, the demon beast group has lost one-tenth of it, and the Lingzi laser pulse cannon will start to strike a second blow ten seconds later, ten, nine, eight, seven......"

Rumble!

Another loud bang.

At this time, on the city wall, on the horizon as far as the eye could see, a large number of black shadows could already be seen in the distance like a wave.

The voice of the electronic announcement also seemed to be solemn: "The demon beast group has entered the defense line for one kilometer, please prepare for battle......

Woo! Woo! Woo!

Another siren sounded, which was the order for the whole army to attack, which was equivalent to a charge trumpet.

Suddenly, one after another mechanical soldiers on the city wall gathered into a humanoid defense line and appeared outside the city wall, like a torrent of steel, rushing towards the black and oppressive demon beast group.

After these mechanical soldiers, there are cultivators on the human side, they act as decapitation, and among the general demon beasts, there will be a king, and all they have to do is to kill this demon king.

As long as the demon king is killed, then the morale of the demon beasts will be greatly reduced, and the battle will be easier.

However, over the years, the demon beasts are not unintelligent beasts after all, and those who can cultivate into demon kings are at least equivalent to having the strength of the human god realm, after experiencing several demon kings being killed, these demon kings have also become smarter, they will secretly hide in the demon beast group, not being discovered, until they completely rush into the steel army, they will reveal their huge figures.

But the human side is not vegetarian, the monster beast has a countermeasure, and the human will naturally change its tactics at the same time.

Therefore, each area is arranged to have a god stage monk stationed, which naturally avoids such a situation, no matter how the demon king hides, under the original spirit of the god stage monk, he will eventually be found.

At this time, the heroic woman in red suddenly looked in one direction and said loudly: "Found it, it's the Silver Moon Demon Wolf King!" ”

In an instant, the woman slapped the top of her head, and a small silver-white sword with a size of three inches burst out from the center of her eyebrows, which grew larger in the wind and turned into more than a foot long. ”
