"The belly button of the planet?" Zhang Ping became more and more curious, this statement is really magical.

I had heard Huang Shaowu talk about the problem of subspace, that is, the cave sky, and Master Gu Yanshan also briefly explained the situation of the connection of the 54 caves of Damengze.

But whoever it was didn't say the word 'belly button'.

Fang Shilu continued: "In the human body, the navel eye is the most important hub. During the fetal period, we receive energy and nutrients from the mother through the belly button; In the same way, the planet draws energy from the void in this way.

It's cumbersome to explain in a scientific way, and I still haven't understood it many times when scientists explain it. However, in the words of Chinese tradition, this is the place where the dragon veins converge, drawing spiritual energy from the void, and then extending along the dragon veins to all corners of the planet. There are many subspaces here, which can be called subspace groups.

And the Longshan Cave Heaven like Qizhou City can only be regarded as a dragon's cave on a dragon vein. ”

"Oh!" Zhang Ping suddenly realized. This explanation is simple, clear, vivid, and easy to understand.

Fang Shilu continued: "Like the navel eye of the human body, it is also important and fragile; The most important thing is that as the navel of the planet, there are too many large and small subspaces, and the overall channel is wide, which is conducive to aggression and attack.

As long as this place can be disturbed, or even cut off, it can gradually dry up the vitality of a planet.

For example, Mars in the solar system, we later found that the reason why Mars turned into a death star, in addition to the public information, the most important thing is the collapse of the subspace group of Mount Olympus.

Archaeological discoveries show that the Martian Rift Valley is the product of interstellar warfare, and that Mars was a living planet more than three billion years ago, but then it was deserted. ”

Zhang Ping nodded.

Fang Shilu continued: "As for why they attacked us here, because ...... This planet itself was snatched by us, from the hands of the demon clan. Not only this planet, but also many planets, were snatched from the demon race, the barbarians, and even the god race, as well as from the civilization that also belongs to the human race.

Don't look at the starry sky is big and there are many planets, but none of them are superfluous. If we want to get living space, we can only grab it. Of course, other civilizations are also grabbing.

So why attack us, strictly speaking, the reason is actually very simple. This is a war of survival, and every civilization must not stop making progress and expanding its living space, otherwise it will be annexed, enslaved, or even extinct.

And survival is the biggest reason. In order to survive, do whatever it takes. Attacking our cave heaven and so on is all trivial. Of course, we do.

Civilization is like a tree, once it stops growing, it decays.

As a member of China, whether it is for the continuation of civilization, or for the growth and development of civilization, and for its long-term survival, we must fight.

In today's interstellar environment, it must be remembered: forgetting the war is dangerous!

Although it is said that the warlike will die, it is better to die strong than to survive. The existence of enslavement has no meaning. ”

Zhang Ping's face became more and more solemn.

There was a roar next to it, and a row of super trucks more than ten meters high rumbled past; On the compartments of these large trucks, three huge mechs are pulled. These steel monsters shimmered with a seeping cold light. But seeing these steel monsters, what Zhang Ping remembered in his mind was not war, but pride.

Fang Shilu finally launched a spell, forming a flying cloud that flew with Zhang Ping, looking down on the devastated land.

In order to facilitate Zhang Ping's observation, Fang Shilu even used a spell to condense two huge water system spell concave and convex lenses to form a telescope to facilitate Zhang Ping's observation. Of course, this also avoids Zhang Ping from getting close to dangerous places such as battlefields.

The ground here is full of craters, and the road passes around the craters. It's not even a road, it's a road run over by a large truck.

From high in the sky, you can see that at the end of the cave, you are at war. Rows of rockets shot out like waterfalls; On the periphery of the cave, you can vaguely see monsters like tides.

These demon beasts are not afraid of death at all, and they are endless. At the edge of the cave, there was already a river of blood, but the demon beasts were still in an endless stream.

Looking at the tragic scene, Zhang Ping couldn't help but exclaim: "Aren't these demon beasts afraid of death?" There are so many demon beasts, how much loss does the demon clan have? ”

Fang Shilu shook his head: "It's not the demon clan that fights here, it's the barbarian clan. Barbarians can graze monsters in the starry sky. To them, ordinary monsters are just like our robots. And they cost less than our robots.

After the robot is damaged, most of the recycling is scrap iron, and the core chips and hosts are basically scrapped. In addition, robots are made up of many materials, and recycling useful materials requires a complex industrial process.

But the barbarians only need to recover the flesh and blood to re-cultivate the demon beasts. Even if the flesh is contaminated, there are some plants and insects in the barbarians that can absorb radiation. There are so many miraculous beings in the universe. There are even electromagnetic life forms that depend exclusively on radiation for survival.

They will use plants or scavenging bugs to absorb the flesh and blood, and then raise monsters through the food chain. They will even transform planets to cultivate demon beast legions. Finally, these monsters are controlled by special means.

Barbarians and demons are almost similar. However, the barbarians are closer to the human race, and the demon race is closer to the demon beast, and the demon race and the demon beast generally live together and live together.

At the beginning, Qin Huangxing was a demon beast cultivation base of the demon clan. ”

Zhang Ping could only nod, there were too many things he had been exposed to today, and he didn't know what to say for a while.

While he was talking, suddenly the rocket car stopped firing, and through the spell of Fangshi Road, Zhang Ping clearly saw the soldiers screaming and waving to the rear, but the rear waved his hand and shook his head, obviously the logistics could not keep up.

Fang Shilu spoke again: "This rocket technology is very old, but it is really useful. It's just that the consumption is also large. Hardly used for non-emergencies. But in reality, here there are almost one emergency after another, and there is always not enough ammunition. ”

As he spoke, the mighty army of demon beasts in front of him continued to advance like a flood, crossing the defense line of the two world cave heavens, passing over the craters and corpses, and rumbling over.

The cannon began to roar, and the frantically advancing demon beast army was like a wave cut off by the waist.

But at this moment, giants with a height of more than ten meters appeared, and 'they' brandished exquisite 'iron rods' in their hands and heavy armor on their bodies, rushing towards the mountains and seas.

There were sparse rockets and missiles that fell, and these giants easily swung iron rods to fly these attacks. Some of the missiles exploded, and they couldn't do much damage to these giants.

"Electromagnetic cannon, electromagnetic cannon!" Zhang Ping, faintly, heard such a shout. Needless to say, it's the magic effect of the ashlar road again.

Then I saw that there were several extra-long electromagnetic guns in the army that raised their barrels, and then red rays of light flew out. This is caused by the friction of a metal ball flying at high speed against the air.

I saw that the armor on the first few giants suddenly cracked, and some of the giants' bodies were dented and their flesh and blood collapsed.

But then the giants suddenly roared in unison, and the iron rods in their hands smashed to the ground, and a huge barrier appeared. The electromagnetic cannon was fired at the barrier, and it stopped after a dozen meters of difficulty, and the barrier only trembled.

The giant continued to advance, but only rushed for a few minutes and began to retreat; But after retreating a few steps, he suddenly sprinted again. After repeating this several times, they actually launched a sprint, and thousands of giants stepped on neat steps, and a transparent barrier rose in front of them.

All kinds of attacks are almost impossible to break through on the barrier, even the electromagnetic cannon. But the attacks are constantly going on, and they are also weakening the opponent's total defenses.

In the rear, hundreds of tall mecha were ready, and the big knives more than ten meters long were unsheathed, and they were imposing.

Seeing this, Zhang Ping couldn't help but exclaim: "Why don't you use nuclear bombs?" ”

"You're overestimating the power of a nuclear bomb. The important thing about a nuclear bomb is that the attack power of the area is strong. But when it comes to the unit area, it can't even reach one-tenth of the electromagnetic gun.

There is also the power of the mecha chop, combined with the power of the mecha itself, the weight of the long knife, plus the torque, etc., the power of the long knife slash is also devastating, and the unit attack still has several times the power of the nuclear bomb. In particular, some of the top mecha controlled by the Yuan Infant Stage have an attack power that even exceeds that of ordinary electromagnetic guns. ”

Zhang Ping looked at it in a daze for a while, and suddenly asked: "Then why not vigorously develop intelligent equipment and intelligent electromagnetic guns?" ”
