Chen Hao was indeed pondering, he was recalling everything about the cracks in his memory.

There are two views in history in the formation of void cracks.

One view is artificial theory, which believes that the void crack was opened artificially by the demon clan.

Another view is the natural crack theory, which believes that the void crack is a fold caused by the superposition and compression of two spaces on each other. When the fold reaches a certain level, it will rupture, thus forming a channel for communication between the two worlds.

After a thousand years, it can be basically proved that both of these views are correct.

After many investigations by star cultivators, it was basically confirmed that the initial space crack was opened by the main sect’s traitor.

The first space crack opened was like opening Pandora's box. One by one, one space crack after another appeared one after another, and the army of the demon clan began to slowly appear on the earth.

However, not all the sources of space cracks are artificially opened, but they are also naturally formed.

It can even be said that the space cracks opened now are the extensions of the first space crack opened by human traitors.

And according to the investigation, in a certain period of ancient times, the human world and the demon world were connected to each other, and there were huge channels for communication between each other. The channels between the two worlds were destroyed or even completely isolated were what happened later. As for what happened, what is now unknown.

Although it can artificially open a space crack, it is not easy for the demon race to open a space crack.

The traitors of the main sect found a space crack ruin from the extremely ancient times and activated it, thus opening the passage between the earth and the demon world. Otherwise, their power alone would never be able to open the crack to the demon world.

It can be said that the initiator of everything is the traitors of the people who welcomed the sect!

All things have their beginnings and ends. There are many necessary conditions for the birth of a void crack, and it also requires the opportunity to overlap folds in space. It can be said that the requirements are very strict, which is a special situation generated by countless coincidences.

The space cracks that can only be created by such complex and precise conditions are actually very fragile and extremely unstable.

In this era, people do not know about space cracks, so they tend to use huge explosions to destroy space cracks, thereby causing space collapse cracks to be bridged.

But if you have a deep understanding of the reasons for the formation of the void crack, you can exchange the greatest results at the lowest cost.

If one of the necessary conditions for the formation of space cracks can be erased, the void crack will collapse and close, returning to its original blocked state.

...

Academy of Sciences.

Jiuxing Hanmei lowered her eyes and sat on a wide seat that was extremely disproportionate to her thin body, looking like she was asleep.

Her performance was incompatible with the noisy sounds around her.

"I have lost twenty disciples and can't continue like this. These disciples are all hopes in my human race. The light of the future. If I continue to consume this, the future of the human race will be destroyed." A hoarse voice sounded like a fire covering his face, and it was obvious that he was really distressed.

"You have lost twenty disciples, and I have also lost twenty disciples. We have already trapped in nearly hundreds of disciples. For some reason, the demon clan is extremely persistent in this space crack and holds it to the death. He would rather pay huge casualties than we want us to bridge the crack here. I think this crack is definitely not simple, and there may be something unknown hidden behind it." The one who spoke was Shu Mo Han, the grandfather of the bottle cap.

A burly man with a rough face buzzed and said in a buzzing voice: "I think so too, so we will destroy this crack in the space no matter how much it costs."

At this moment, there are three old masters from the Star Hall, an academician of the Academy of Sciences, and two commanders of the military region.

Jiuzhou is located at the intersection of the North Line Military Region and the West Line Military Region.

So the people who came here were Commander Hu and Commander Huang.

As Commander Huang, he looks majestic, with white beard, white hair, a body full of tendons, a dark face, especially his eyes, and his eyes are powerful without anger, and his whole body is filled with a fierce murderous aura.

Commander Hu sat next to Commander Huang, and no matter how he looked, he looked down. It was not a matter of height, but a matter of momentum.

In fact, Commander Hu is indeed a young boy in front of Commander Huang.

Commander Huang is 136 years old this year. Although he is incomparable to the elders of the Star Palace, he has already had a very rare longevity in the military.

He experienced hundreds of battles with the demon clan, and his parts were replaced with 70% of them, including arms, arms, eyes, ears, mouths, teeth, and even three sections of his spine, and his skull was replaced with alloy.

It can truly be called a great military merit, and various medals are piled up like mountains.

No one in the entire central government can compare his qualifications with him. Even these old people, although they are old, should be polite when facing Commander Huang.

His reputation was exchanged for his own life and polished with parts on his body.

Moreover, Commander Hu had served as a soldier under Commander Huang before, so even if Commander Hu is now on par with Commander Huang, he still dares not be arrogant. As long as Commander Huang is here, he will still be a new recruit. He must be honest and sit upright.

"As far as I know, two earth demons gathered at the void crack in Jiuzhou. They each brought tens of thousands of demon soldiers, plus the demon clan that was constantly surging from the void crack, and the demon soldiers gathered from other places, which totaled about 50,000."

"There are at least thirteen demon generals at the two ends of the earth demon level, and the demon spirits are about 5,000 to 8,000. The rest are all demon soldiers. If you want to deal with such a large-scale demon clan, you can only minimize casualties..."

Commander Huang's voice was very rough, and the words he spit out were like nails, poking on the table.

His eyes were sharply staring at the old people present.

The three old men were pondering and silent at this moment.

Commander Hu licked his lips, and he knew what Commander Huang meant.

Academician Jiuxing Hanmei, who had been dozing off at this time, slowly opened her eyes: "Do you want to use a killing weapon to razor a hundred miles to the ground?"

Commander Huang sneered and said, "Yes, since they are so willing to guard the crack in the space and continuously dispatch demon soldiers there, it just turns into a big target. If a thermonuclear bomb is dropped, I am afraid that only the earth demon can leave alive and kill 40,000 demon soldiers, more than 8,000 demon spirits, and thirteen demon generals in one go is not worth doing this deal?"

Everyone remained silent.

They have done this kind of nuclear attack on the demon race before, but the Western government has done it more purely.

But after the attack, many demon races were indeed killed, and at the same time, they also caused irreparable trauma to the environment.
