When the residual power of this salvo finally dissipated, the sinkhole had turned into a sea of ​​fire.

Dozens of blazing mushroom clouds burned the aerial jungle intertwined with thousands of vines.

The huge recoil caused all the train guns to tremble three times. Their support legs were uprooted, and the derailed wheels plowed deep marks on the ground as hard as iron.

The radiation released by the strong crystal reaction had not yet dissipated, and there were still ripples of psychic energy visible to the naked eye in the air. The artillery officers rushed forward wearing radiation-proof suits and lead jackets to quickly reset the train cannon and load the second

Wheel of artillery.

Ordinary soldiers cannot operate in such a harsh environment as hell, so those who rush forward are almost all "suicide squads" composed of extraordinary beings.

Perhaps, the death squads are just low-level transcendent beings with one-star spirit realm or two-star spirit realm at most.

There is no such exquisite killing skills and unparalleled force as Meng Chao and Lu Siya.

But they still used their bodies, ignited by spiritual flames and made of iron and steel, to fight in a battle that changed the course of civilization.

Because the radiation was so strong, every minute, the death squads had to evacuate the train gun and go to the "safe zone" a hundred meters away to take a breather.

They took off the lead plates and radiation protection suits, and their pale faces were covered with beads of sweat the size of soybeans.

Some people even suffered from excessive radiation, and pustules and dark spots appeared on their skin.

But when ordinary soldiers volunteered to perform their duties on their behalf, these young officers of the Red Dragon Army waved their hands without hesitation and rejected the soldiers' kindness. After gulping down genetic medicine and cell repair agent,

Putting on his helmet and armor again, he rushed towards the super-radiated train cannon.

The second round of artillery fire roared, accompanied by human roars, and exploded over the sinkhole.

Because Meng Chao and other exploration team members were well prepared in advance, the bombardment of the train artillery was very targeted.

They are all aimed at places deep in the tiankeng, where there are a large number of underground cavities, and where the spiritual magnetic reaction is particularly strong.

Meng Chao and other exploration team members have identified fifteen such intricate maze-like caves in total.

There are several entrances to the caves, with strange spiritual flames constantly spurting out. They look like dragon pools and tiger dens.

If we directly send soldiers to attack by force, I am afraid that thousands of troops and horses will not be able to fill these bottomless pits.

But the people of Longcheng, who have an absolute advantage in firepower and have been suffering from the late stage of "firepower deficiency syndrome" since decades ago, will not engage in "hand-to-hand combat, heart-to-heart combat, and flooding every inch of land with blood" with the monster civilization.

Trick.

The problems that can be solved with train guns cannot be solved by extraordinary people.

For problems that can be solved by extraordinary beings, there is no need to sacrifice the precious lives of ordinary soldiers.

Use strengthened and modified "earth-penetrating artillery shells" with a special structure to penetrate tens of meters of rock formations and explode violently in the underground space.

Even if the monster mastermind cannot be killed, all the oxygen in the ground will be burned out.

As long as the opponent still belongs to the category of carbon-based organisms, there is no reason not to accept this method.

As the torrent of steel rolled forward, the Dragon City Cavalry opened up more and more attack channels and heavy artillery positions deep in the jungle.

Thousands of heavy artillery, large and small, have been pushed to the edge of the sinkhole, allowing them to command a commanding height and pour firepower into the depths of the sinkhole unscrupulously.

Even the Longwei giant cannon fired from the base camp dozens of kilometers away.

Although the shooting accuracy cannot be as high as the naked eye observation and close range shooting, the terrifying power of one shot, which can be destroyed for several miles, makes the "shooting accuracy" meaningless.

This scene before his eyes once again awakened Meng Chao's memory fragments from his past life.

Let him understand why countless otherworldly races in previous lives would cry out in horror when they saw the steel torrent of Dragon City Civilization: "Xenoscourge! Xenoscourge!"

The pride of being a "natural disaster" arises spontaneously.

When the intensive bombing of the sinkhole lasted for three full hours and the ninth underground cavity was blown to the ground, the Dragon City Cavalry finally located the location of the ultimate lair of the monster civilization.

First, a scarlet spiritual flame nearly a kilometer high shot out from deep underground, piercing a bloody hole in the smoke-filled sky.

Immediately afterwards, between the pit full of flames and the sky full of gunpowder smoke, there was an extremely shrill howl, one after another.

Groups of deformed and twisted mushroom clouds were torn apart, and a huge insect-like monster appeared among the destructive hurricanes.

At first glance, this guy looked a bit like the first super beast that Meng Chao killed after his rebirth - the ghost-eyed golden-winged flame insect.

But judging from the comparison of the size of the four shining golden wings and the mushroom cloud, its wingspan is at least nearly a hundred meters long.

In a sense, a nearly 100-meter-long moth is more capable of tugging at human heartstrings than a nearly 100-meter-long dinosaur.

Not to mention this super giant "ghost-eyed golden-winged flame insect". The patterns on its wings are a hundred times more complicated than ordinary butterflies. It's like a hundred deep eyes opening at the same time, trying to absorb the souls of all humans on the battlefield.

Absorb it all.

Human beings who accidentally saw its wings turned pale, as if they had been struck by lightning, and their spiritual defenses were in danger.

"The doomsday beast!"

Sensing the ferocious aura it released, Meng Chao got goosebumps all over his body and blurted out subconsciously.

It was too late, but it was too late. This super giant "ghost-eyed golden-winged flame insect" with ferocious flames that was almost a doomsday beast, only flapping its wings twice, crossed the sea of ​​​​fire and flew to the edge of the sinkhole.

On the edge of the sinkhole, a dozen armored airships were suspended, risking their lives to observe the bombing effects and provide ballistic calibration for the heavy artillery cluster.

Seeing the doomsday beast coming towards them, they all dispersed like a frightened swarm of bees.

But after all, the steering and escape of an armored airship are not as fast as a supersonic fighter jet.

The super giant "ghost-eyed golden-winged flame insect" has shaken off the large phosphorus powder on its wings and ignited it with the spiritual flames ejected from its mouthparts.

In the sky, above the red sea of ​​fire lit by humans, there suddenly appeared a blue sea of ​​fire that seemed to be extremely cold.

An armored airship couldn't dodge and was about to fall into the blue sea of ​​fire.

The driver drove the spar engine desperately, with the engine roaring and bursting, squeezing out the engine's ultimate potential again and again, just like someone kicked one after another behind the armored airship, causing it to narrowly escape the purple

Invaded by the sea of ​​fire, it fell crookedly into the depths of the jungle.

The monster that followed wanted to pursue it, but it seemed as if it had missed its breath. The second flame it spat out was weak, like a small winding snake that disappeared before it could swim more than a hundred meters.

"This is impossible……"

Meng Chao was very surprised.

Judging from its size and aura, this super giant "ghost-eyed golden-winged flame insect" is definitely the king of monsters - the doomsday beast.

But if it were a real doomsday beast, it would never let a small armored airship escape its hunting range.

Even if it was knocked dizzy by heavy artillery fire, it would still be impossible.

"This doomsday beast... seems not to be fully developed yet."

Lu Siya squinted her eyes and observed for a while, then said, "Its wings are still wet!"

Meng Chao's mind was spinning and he suddenly realized.

That's right, the wings of this super-giant "ghost-eyed golden-winged flame insect", although wide, are wrinkled and wet, with a lot of mucus attached to them, as if they have not been fully expanded.

Its body also didn't look plump, and many parts were shriveled. It was also covered in mucus, and there was even something like a cocoon attached to the mucus.

In particular, its tail still retains the characteristics of a large number of larvae, and does not have the common luminous tentacles of butterfly monsters.

This is a doomsday beast that has not yet completed its evolution.

They are "premature babies" whose process of "emerging from cocoons and becoming butterflies" was forcibly interrupted by human artillery fire.

At this time, in the depths of the sinkhole and in the sea of ​​fire, more and more ferocious shadows of super giant monsters emerged.

Meng Chao saw a monster sixty or seventy meters long, with a body like a pterosaur and a head like a plesiosaur. It was also covered with a crystal clear translucent carapace, like a layer of crystal armor, as if it could It absorbs all the heat from the surging sea of ​​fire, then releases it in a targeted manner through complex refraction, reflection and diffraction.

Astonishingly, it is the most troublesome beast among the doomsday beasts - the Diamond Nine-Headed Dragon!

However, the body length of an adult Diamond Hydra usually exceeds a hundred meters, and it has nine extremely renewable heads. Even if eight are exploded at once, as long as there is one head left, there is a chance to escape and come back.

This "Diamond Nine-Headed Dragon" has obviously shrunk a lot, but it only has four heads. The crystal carapace does not cover every inch of skin around the body. At most, it covers the vital parts, and in the gaps between the vital parts, it is still fragile and fragile. The tender pink flesh was burned black by the tongues of fire constantly licking it.

This is also a "premature baby".

There is also a doomsday ferocious beast, which looks like a hybrid of a spider and a flea magnified tens of thousands of times, but has more than fifty thin and long, sickle-like limbs.

When the densely packed blade limbs are swung, it is enough to give any trypophobia patient a heart attack.

However, it is also not fully developed, and the carapace surrounding the blade limbs is not hard, but is wet and soft like the wings of the super-giant "Ghost-Eyed Golden-Winged Flame Insect".

Bai had dozens of bladed limbs, but they couldn't even support his body, which was dozens of meters long. He staggered after taking two steps, as if he was about to fall over.

Meng Chao knew that many huge doomsday beasts had organs like "anti-gravity engines" or "magnetic levitation generators" growing in their bodies.

They use the repulsive force between the magnetic field of life and the magnetic field of the planet to get rid of the gravity of the earth and support the body that is nearly 100 meters long and weighs nearly 10,000 tons, standing tall on the earth.

The so-called limbs are just the icing on the cake.
