As we all know, it is basically impossible to grow crops in mineral-rich areas.

Coupled with the pervasive demonic energy in the demon world, food is a major problem faced by the demon clan.

When the demon world was established, the human powerhouses also expected such a situation. At that time, the relationship between the two parties was in the honeymoon period, so the human powerhouses could not eat ugly.

We can't let people guard the door and let people starve to death!

Even a ruthless landlord can't do such a thing. After all, it is necessary to focus on a sustainable development.

And the control of the powerful human beings over the monsters lies in food.

Although the demon clan believes in the law of the weak, the fruits and vegetables of human beings are also indispensable things. At least for the high-level demon clan, these luxury accessories are still very meaningful.

Long before Zhang San became the soul of the Immortal Veins, the demon clan and humans were trading with each other!

At that time, Yan Guo made a lot of scientific and technological products by relying on various precious materials in the demon world.

It's a pity that the demon clan tore up the treaty because of the excessive pressure of the black soul, and the two sides became evil until the rise of Liu Zhengyang.

Now that the city defense system was activated, the thick energy shield pushed out and directly touched the front of the battle between the two sides, stubbornly blocking the attack of the black soul parasite.

"Although I hate humans, I have to say, this thing is really good!"

The leader of the advance team of the demon clan is a tauren, and he speaks in a humming sound.

The most striking thing is his tendon.

The sturdy muscles have a sharp impact, and the pair of black horns on his head point straight to the sky, giving people a sense of rebelliousness.

The monster next to him said in agreement: "Indeed! This is a treasure, otherwise our brothers don't know how many will be parasitized by those disgusting things!"

Speaking of this, the tauren looked at the burly figures standing outside the protective shield, and a look of sadness flashed on his face.

Although the demon clan doesn't pay attention to what it takes to be safe, the tauren is very angry to see the subordinates who get along with each other day and night suffer such pain even if they die.

The long axe in his hand slashed directly on the ground, and then he began to wear rough clothes, and his eyes were a little scarlet.

"These damned guys, as long as the demon emperor leads us, we can definitely drive them out!"

The tauren's words are not much agitation.

Mainly because the monsters around him are too tired!

"It's this thing again!"

Poles frowned and looked a little dissatisfied.

In the past, when fighting with the monster clan, there was no such thick hood. Basically, the battle is over now. Those big but grotesque guys have long been submerged by the Kuroshio!

But the situation is completely different now, and Poles is a little annoyed.

"Isn't it just a broken cover! Polly, take someone to smash it for me!"

The body of the entire Mengtan family was instantly shrouded in golden light, and then the golden light circulated, and the bodies of these people began to become unusually strong, like walking giants, swaying to the protective cover of the city defense system.

Then the huge fist slammed on it fiercely, causing a sudden tremor.

"These guys are just wasting their efforts!"

The tauren sneered, it was not the first time they used the city defense system.

If you have to sum up, he only has two words, really fragrant!

Past experiences all show that what the Mengtan family is doing now is nothing but futile! At least it is impossible to break this protective shield!

Thinking of this tauren, he could not help but laugh, maybe this is the power of that technology!
