A clone of Yang Ying, piloting the Thunder God, arrived at the center of the battlefield. Before their very eyes, a surging torrent composed of monstrous beasts several stories high rushed toward them. With every heavy footfall, thousands of thick legs slammed into the ground each second, causing the rock and ice beneath to crater deeply, kicking up shards of stone and ice that billowed into a smokescreen obscuring the horde behind.

Even on a planet with such low gravity, the sheer size and weight of the colossal beasts carried immense intimidation, advancing like roaring high-rises.

Several rows of the Sphere Army’s battle vehicles stood before the Thunder God. As they charged the beast horde, they ceaselessly fired upon the front ranks of the giants. Beams of colorful light erupted from the muzzles, and rows of missiles shrieked as they struck the beasts, tearing flesh and painting them crimson. However, the wounded beasts became even more dangerous; foregoing beam attacks from their horns and teeth, they charged madly into the Earth Army’s lines with bloodshot eyes.

Every vehicle in their path was overturned, some even flung dozens of meters into the air.

As soon as the front-rank giants fell, the beasts behind stepped directly over their corpses and kept coming, showing not a hint of alarm or fear.

The three Thunder Gods spread out, maintaining a distance of about a hundred meters between each unit. They stood in a line behind the armored division, raising their arms and aiming two Level Five cannons directly at the beast horde ahead. The two Level Four Hammer-Spike turrets on their shoulders were also aimed forward, where pinpricks of light coalesced before the muzzles.

Boom! Boom! Boom!

Six Level Five cannons, twelve Level Four cannons, plus hundreds of thousands of missile rain, roared into the beast horde!

“Everyone on the flanks, watch out!”

On a tank positioned near the foot of Thunder God Unit One, the division commander of this Earth Army Armored Division—a brown-haired Major General in his early forties—leaned out of the turret and shouted urgently into his headset. Dwarfed by the towering Thunder God, the tank looked insignificant, like a tiny mouse.

The Thunder God’s offensive targeted the rear ranks of the horde, not the vanguard already entangled with the armored units; engaging the front wave risked friendly fire.

Eighteen pillars of light instantly pierced several massive beasts in the center of the horde. Some beams sliced through two, or even three giants at once; tissues and organs swept by the light vaporized instantly.

As the Thunder Gods fired, they simultaneously swept their hands upwards, extending the light beams toward the rear of the horde. Like bulldozers, they swept across hundreds of meters, igniting violent explosions within the enemy mass.

The resulting debris and dust rose hundreds of meters high, and a shockwave carrying the pulverized matter slammed into the Earth Army’s lines, obscuring the soldiers' vision.

Hundreds of thousands of missiles plunged into the swirling dust cloud. Immediately following, vast sheets of reddish-hot flames erupted within the smoke. Updrafts expanded violently, pushing the dust even higher. Soldiers near the front line suddenly felt a fine drizzle descending from the sky; some reached out a hand and were horrified to find the rain was a deep, bloody red.

Ganymede’s thin atmosphere caused the dust to dissipate quickly. Once the shockwave passed, the smoke gradually thinned, revealing a cleared patch within the beast horde. Ten or more large and small craters dotted the open ground, their diameters ranging from thirty to a hundred meters, with wisps of blue smoke still curling from the pits.

Flesh, corpses, and heavily wounded, prone beasts were scattered around the edges of the craters, a scene radiating outwards. At least five hundred beasts within that entire area were engulfed by the explosions.

Yet, the majority of them managed to push themselves up on their limbs, shake their heads, and resume their charge toward the Earth Army lines.

Yang Ying observed that in this wave, approximately twenty percent of the ancient giants were instantly killed, about ten percent were gravely wounded and combat-ineffective, while the remaining seventy percent sustained only minor injuries; the shockwave alone wasn't enough to fell these thick-skinned behemoths.

High above the battlefield, two Phantom fighters moved like true ghosts, completely unnoticed by the fighting below. Suddenly appearing directly over the horde, they aimed their remote-controlled cannons at the vanguard beasts mixed in with the armored troops and opened fire abruptly!

The remote cannons were not armed with Uranium Guns, nor even the weakest Level One cannons from the Uranium series. These were the more powerful Level Two cannons. Level One cannons were typically used on light tanks, fighters, or fast patrol skiffs, capable of piercing ten millimeters of alloy armor easily. But Level Two cannons were far superior; even heavy tanks and small warships were only marginally resistant to this level of firepower.

Yang Ying and Dao Feng had selected targets carefully: the beasts’ eyes, noses, or other vital areas with lower protection. If the angle was calculated correctly, a single shot could punch through the eyeball and directly into the brain.

Under the relentless barrage of remote fire, the casualty rate of the beast legion doubled, and their forward momentum slowed significantly. The cost of every step forward had suddenly increased. Beasts in the rear were forced to push through the corpses of their comrades just to advance.

“Good! Strike while they’re weak! Increase the offensive intensity, boys! Give me everything you’ve got!”

At the foot of Thunder God Unit One, the armored division commander, though unaware of the reason for the sudden, fierce attack raining down from above, clearly recognized the opportunity presented by the remote fire. The instant the remote cannons erupted, he charged forward, gesturing sharply with his hand, ordering an advance. The armored units’ impact intensified once more.

The rear beasts, enduring the Earth Army’s artillery fire and the remote beams, forcefully crossed the craters blasted by the Level Four and Five cannons, merging with the wounded beasts to surge forward again. At this point, only about a thousand beasts had been lost, roughly twenty percent of the total horde, yet the rest maintained their full momentum.

The defense batteries of Fortress Number One also took notice of the massive Thunder Gods, diverting the vast majority of their firepower toward them.

A barrage of beams, missiles, and shells exploded against the Thunder Gods’ hulls, including some heavy artillery rounds, forcing them to stagger backward. The armor on their surfaces was depleting faster than it had during ground combat on Callisto.

Suppression of enemy artillery is the primary task of the artillery corps. However, with the appearance of the Thunder Gods on the battlefield, the ancient legion clearly marked the Earth Army’s artillery as the secondary target, directing beams and missiles at the Thunder Gods.

Firepower below Level Three had limited effect against the Thunder God’s thick armor; only the high-energy defense cannons were of concern.

According to intelligence gathered by the Earth Army, following the battle on Callisto, the defensive systems of the Ganymede fortress had been specifically upgraded. They now fielded twenty Level Six defense cannons capable of engaging the mecha units, posing a significant threat to the Thunder Gods’ advance.

However, utilizing the Thunder Gods to capture Fortress Number One was the strategy decided upon in the war council. To pave the way for the mechas, the Earth Army dispatched numerous fighters to destroy those high-energy defense cannons.

The Earth Army currently held the advantage in Jupiter orbit, allowing them to commit more resources to supporting the ground assault than they could on Callisto. Although the aerial battle was deadlocked, the Earth Army maintained a solid upper hand.

To neutralize these Level Six defense cannons, the Earth Army's fighter squadrons paid a heavy price in casualties just to break through the Fortress Number One’s dense anti-air barrage and destroy them.

At this moment, the three Thunder Gods, weathering the bombardment of lower-energy fire, unleashed another attack, carving out another clearing within the beast horde. Meanwhile, Yang Ying and Dao Feng continued to reap the giants with their remote cannons. Fourteen Level Two cannons concentrated from a single remote platform could exert the power of a Level Three cannon, capable of even piercing the skulls of the White Rhinos and White Elephants.

Far behind the Earth Army’s lines, the siege tank units of the Tranney Corps also found favorable firing positions. They deployed their stabilizers, elevated their barrels, and used airborne observers over the battlefield for targeting, blasting shells into the beast horde.

The siege tanks fired hyper-velocity solid slugs, which were far more lethal to these giants than concentrated energy beams. The kinetic energy carried by the shells could instantly tear their bodies apart.

During the first wave of bombardment, Yang Ying and Dao Feng, observing from above, saw several twenty-meter-tall White Elephants struck dead center by shells. Their room-sized heads exploded instantly, sending a downpour of blood mixed with trunks and tusks flying dozens of meters away.

A few ten-meter-tall White Rhinos were hit squarely and vanished from their location in an instant, leaving behind only a large pool of blood and shredded meat—the White Rhinos were considerably smaller than the White Elephants and less resilient to solid projectiles.

Those giants that avoided direct hits fared little better; some had legs severed, others had half their torsos blown away, their organs and intestines spilling out amidst bright red blood, causing them to collapse after just a few struggling steps.

With the siege tanks joining the fray, an invisible line seemed to form before the beast horde. Living giants could not cross it. Before reaching that line, they were either eliminated by the Thunder Gods, shot down by remote cannons, pulverized by siege tank shells, or dealt with by the Earth Army’s armored division.

“Attack! Attack! Attack!”

At the foot of Thunder God Unit One, the brown-haired Major General had entered a state of fervor. He drew the command saber from his waist, pointed it forward, and ordered his command tank to charge ahead at full speed.

This armored division had already lost nearly twenty percent of its strength, but after witnessing the combined power of the Thunder Gods, remote cannons, and siege tanks, their confidence soared. They had no doubt they could shatter the beast horde. The blood and fire on the field ignited their desire to advance, and under the Major General’s command, they poured on the power and charged forward.

Seeing this, Yang Ying’s clone also controlled his Thunder God to take a step forward, advancing alongside the armored division.

Fortress Number One’s defense cannons continued to hammer the Thunder God, most impacting the area around it, with only a fraction striking the mecha itself. Even so, at least two to three hundred shells per minute slammed into the Thunder God, battering its armor until it was pockmarked. The clone in the cockpit felt the entire visual field shake violently up, down, left, and right, but inwardly, he began to admire the brown-haired Major General’s luck.

To remain under such a hailstorm of shells for so long without being obliterated, and still manage to issue spirited commands, spoke volumes about his incredible fortune.
