The existence of anti-gravity organs can allow monsters to control huge bodies weighing tens or even hundreds of tons, as well as tentacles and other weapons with a length of several kilometers, in the combat environment of the earth's standard gravity, to make all kinds of extremely dexterous attacks and dodges.

It's like making an elephant dance on the tip of a knife, giving flesh and blood a scientific basis to compete with the torrent of steel.

The existence of large-scale, high-intensity electromagnetic interference has set the combat environment back 200 or even 300 years at once, to the ancient days when the earthlings had not yet invented any electronic equipment and relied purely on visual observation, close salvo shots, and propeller fighter "dog fights."

It can be said that the "seventy percent martial arts" of the Earth Army were abolished all at once.

These two traits alone make the monster the greatest threat on Earth at this moment.

Not to mention, most monsters have another extremely terrifying and incredible trait or "superpower" around them.

That's the Energy Shield.

It can also be called a defensive field.

In short, it is wrapped around the monster, invisible and invisible, but it is real, and it can play a great role in interference and defense.

With the existence of the energy shield, the sharpest guided weapon of the Earth Army does not pose the slightest threat to the monster.

Even if hundreds of missiles are launched at the same time, it will often only form a wall of the most brilliant fireworks around the monster.

And the monster can emerge from the blazing flames in minutes, unscathed, and launch the most brutal attack on the stunned Earth Army - no, "abuse"!

In the top-secret database of the Earth Army, it is recorded that at the beginning of the revival of the aura, an elite aircraft carrier formation of the Earth Army encountered a monster and launched an over-the-horizon precision guidance strike, "the bullet rains down, and the example is not in vain", but it is impossible to prevent the opponent from approaching the entire fleet at a very fast speed, and then the opponent hit a "super electromagnetic interference", which paralyzed the aircraft carrier formation, and one battleship after another, was torn apart by monsters like toys and sank to the bottom of the sea.

To be honest, it was the darkest and most desperate day since the founding of the Earth Alliance, no, since the birth of human civilization.

Fortunately, this despair did not last long, and experts in the military and energetic circles discovered the strangeness of the energy shield on the monster in the painful encounters or unilateral slaughters.

In a series of combat examples, experts have found that even with energy shields and defensive fields, seemingly thick-skinned monsters are by no means invulnerable, they can withstand the vast majority of cruise missiles, tactical missiles, and the most advanced close-in defense artillery, but are often killed by relatively backward shipborne and airborne artillery, and even machine gun fire.

The most extreme example of the war took place in a sea area near the equator.

The region has just joined the Earth Alliance, and there is not much maritime trade with the outside world, and the person responsible for patrolling the nearby routes is also a new escort fleet that has been put together on a temporary basis.

Such a third-line fleet, of course, is unlikely to be equipped with the most advanced aircraft carriers, Aegis ships and stealth destroyers.

In fact, there are not even "very advanced" aircraft carriers or capital cruisers.

The only thing that the escort fleet can mobilize is the naval equipment of a certain equatorial country hundreds of years ago, and I don't know how many times to turn around, tinkering, patching patches, rusty, squeaking, and small and medium-sized destroyers and frigates that may collapse and sink in the sand when a wave hits.

Even if you look at the markings of one or two hundred years ago, at the beginning of the twenty-first century, these so-called "warships" are old antiques, and they are only worthy of being used as target ships.

In fact, the origin of these warships, probably the same, was mass-produced in the context of global confrontation in the mid-to-late 20th century, and with the easing of international relations, they gradually lost their usefulness, and because of the overall backwardness of technology, the cost of maintenance and maintenance continued to increase, and they were no longer included in the active service of major powers, and were resold or given away to some "friendly neighbors".

After a series of twists and turns, these old antiques who should have sunk to the bottom of the sea as early as the beginning of the 21st century are miraculously still floating on the ocean of the 22nd century, and have ushered in the most terrible enemy in the history of human warfare - monsters!

Everyone, including the crew, who were at the helm of these rusty antiques, without any sophisticated equipment, and even the extreme lack of tactical missiles, fell into despair, thinking that they were going to die.

After all, even the most advanced superweapon of mankind is helpless against monsters, so how can they be spared? It's nothing more than being driven by the survival instinct and doing a dying struggle.

Who knows, a miracle happened!

The monsters, who are not afraid of supersonic missiles, were beaten by these old warships, from the mid-to-late twentieth century, and even from the naval guns of the World War II era, screaming, and there were obvious injuries on the flesh and skin.

In the end, after overturning two antique warships in annoyance, he fled back to the depths of the sea, never daring to show his head again.

There must be a profound scientific truth behind such an incredible miracle, and after analyzing a series of similar combat examples, and using a variety of instruments to scan and probe the body of the monster from a distance, the experts finally came up with an interesting conjecture.

The energy shield that surrounds most of the monsters has an extremely special ripple structure, which is even more ...... compared to ordinary energy bodies Dense, slimy, like, to use a misnomerical analogy, like some kind of "non-Newtonian fluid".

The so-called non-Newtonian fluid refers to the fluid that does not meet Newton's experimental law of viscosity, and its shear stress and shear strain rate are not linear, and have various wonderful properties.

For example, a non-Newtonian fluid that seems to be as soft as a swamp and enough to swallow human beings will not sink as long as a person runs over it at a very fast speed, but can run for tens or hundreds of meters as if it were "floating on water".

For example, under a tower tens of meters high, an inflatable pool filled with non-Newtonian fluids is placed, and a heavy lead ball is thrown down from above, and the lead ball will only slightly smash into the non-Newtonian fluid, but most of it will still float on the surface, instead of sinking directly to the bottom of the non-Newtonian fluid.

However, if the speed is slowed down and the force is reduced, the human feet or the lead ball are slowly immersed in a non-Newtonian fluid, and they will not be hindered too much, but will sink to the bottom like ordinary Newtonian fluids.

The key is speed.

Experts have found that the monster's energy shield will only work when the attack speed reaches a certain value.

The faster the attack speed, the stronger the energy shield's defense.

The attack speed is above three times the speed of sound, and the energy shield's defense is almost 100%.

The attack speed is more than twice the speed of sound, and the defense of the energy shield is also more than 90%.

The attack speed is more than double the speed of sound, and the defense of the energy shield is reduced to about 80%.

At the speed of sound, the energy shield's defense is reduced to 50% or less, and when the attack speed drops to less than half the speed of sound, the energy shield becomes better than nothing, as if it didn't exist at all.

In the past, humanity has been fighting monsters with the most advanced superfleets and "fifth-generation aircraft", "sixth-generation aircraft", and the main means of attack is the use of missiles.

Whether air-to-air, surface-to-air, anti-ship or cruise missiles, their speed is about 600 to 1,200 meters per second, about two to four times the speed of sound.

At such a speed, hitting the monster's energy shield will exert the strongest defensive power, making the missile like a lead ball falling from a high altitude and landing on the surface of a non-Newtonian fluid, its energy is completely absorbed by the special corrugated structure and detonated on the periphery.

In addition, the so-called "missile", as can be seen from the name of its "precision-guided bomb", is a weapon that pursues accuracy, not firepower coverage, no matter how "ten thousand arrows are fired", it is good to have dozens or hundreds of missiles hit the monster at the same time.

This amount is far from enough to tear through the energy shield and cause damage to the monster.

The third-line fleet, which cruised on the equator, was pitifully not equipped with too many advanced missiles and fighters, and its main weapons turned out to be outdated close-in defense guns and slightly modified rockets.

This kind of rocket was not supposed to appear on warships, and even if it did, it was only a "toy" for fighting pirates in the past.

Adapted from anti-tank weapons, the rocket travels at an average speed of only about 200 meters per second, 60% of the speed of sound.

If it were a conventional, 22nd century confrontation between the world's most advanced navies, the use of such weapons would be no different from throwing stones and spitting on enemy ships.

However, in the war against monsters, this 60% sonic rocket has become an out-and-out magic weapon for victory!
