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

Coupled with the demonic atmosphere in the demon world, food is a major problem faced by the demon family.

When the demon world was established, the strong human beings also expected this situation. At that time, the relationship between the two sides was in the honeymoon period, so the strong human beings could not eat ugly.

You can't let others guard the door and let others starve to death!

Even a ruthless landlord can't do such a thing. After all, we must focus on sustainable development.

The human power's control over the demon family lies in food.

Although the demon clan believes in the law of the jungle, human fruits and vegetables are also essential. At least for the advanced demon clan, these luxury ornaments are still very meaningful.

Long before Zhang San became the soul of xianmai, the demon clan and human beings traded with each other!

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

Unfortunately, later, the demon clan tore up the treaty because of too much pressure from the black soul, and the two sides were hostile until the rise of Liu Zhengyang.

Now, after the urban defense system is urged, the heavy energy cover is pushed out, directly against the front of the two sides, blocking the attack of the black soul parasite.

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

The leader of the advance team of the demon clan is a Tauren, and his voice is buzzing.

The most remarkable thing is his tendon flesh.

Strong muscles, looked at the sharp impact, and a pair of black horns on his head pointed directly at the sky, looked at it and gave people a sense of defiance.

The demon clan nearby echoed and said, "indeed! This is a baby, otherwise our brothers don't know how many will be parasitized by those disgusting things!"

Speaking of this, the Tauren looked at those strong figures standing outside the protective cover, and a look of sadness flashed on his face.

Although the demon clan doesn't pay attention to what is safe in the land, the Tauren is very angry when he looks at his men who get along day and night, even if they die.

The long axe in his hand cut directly on the ground, and then he began to wear coarse clothes and his eyes were scarlet.

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

Tauren's words didn't inspire much.

Mainly those demon families around him are too tired!

"This thing again!"

Pols frowned and looked discontented.

In the past, when fighting with the demon clan, without this thick cover, the battle has basically ended now. Those big but strange guys have long been submerged by the black tide!

But the situation was completely different, and pols was a little angry.

"It's just a broken cover! Polly, you take someone to break it for me!"

The whole mengtan family's body was shrouded by the golden light, and then the golden light circulated. These people's bodies began to become unusually strong, like walking giants, staggering in front of the protective cover of the urban defense system.

Then the huge fist hit it hard, which immediately caused a shaking.

"These guys are in vain!"

The Tauren sneered. It's not the first time they have used the urban defense system.

If you have to summarize, he has only two words. It's really fragrant!

Past experience shows that what the muntan family is doing is just futile! At least it's impossible to break the shield!

Thinking of this tauren, he couldn't help grinning. This may be the power of science and technology!
