Regressed with Omnipotent AI on Zombie Apocalypse(FF)

As the reports came in, Scott's face grew darker. The vanguard of the zombie tide—composed entirely of speed zombies like super hunters and raiders—could cross a few kilometers in mere moments.

"The tide is 5 kilometers away!"

"Deploy the tanks!" Scott bellowed without hesitation.

Rumble—!!!

More than three hundred tanks roared to life, their engines growling as they formed a steel phalanx. The tanks rolled forward like ancient heavy cavalry charging into an overwhelmingly larger enemy. Billowing smoke and dust trailed behind them as they plowed ahead, a wall of iron aimed directly at the black tide.

"Fire!"

"Reload!"

The tank crews, made up of ordinary people with minimal training, could only operate at a basic level. But here, on the flat plains surrounding the base, they didn't need precision. Reload, aim roughly, and fire. Every shot hit something, and every hit counted.

As the tanks advanced, they drew closer to the zombie tide. Then, with a deafening roar, the two forces clashed. The fifty-ton steel behemoths tore into the horde, leaving trails of crushed flesh and gore in their wake. The tanks, each equipped with collision buckets and reinforced with spikes, became blunt instruments of destruction. "Crush them!" a soldier roared over the comms as the tanks sliced into the tide.

The battlefield became a chaotic maelstrom. The tanks fired continuously, the gunners inside unleashing bullets from their machine guns. Outside, flamethrowers spewed firestorms that incinerated zombies in their path. But the horde was relentless. Hunters, with claws sharp enough to tear through metal, leapt onto the tanks, scratching and clawing at their armor. The shriek of metal-on-metal filled the battlefield, even overpowering the thunder of gunfire.

Boom! The first tank fell, overwhelmed by zombies that set its fuel ablaze. Flames engulfed the vehicle, roasting its crew alive. The steel tombs burned brightly on the battlefield, marking the sacrifices of their crews. One by one, more tanks succumbed. Tracks were torn apart. Engines stalled. Crews, trapped and desperate, detonated their tanks, taking as many zombies as possible with them.

Rumble—!

The earth trembled as lord-class zombies, towering and monstrously powerful, joined the fray. Even the heavily modified tanks couldn't withstand their strength for long. Although the tanks bought time and killed countless zombies, they couldn't stop the tide entirely. Swarms of zombies bypassed the immobilized tanks and surged toward the Washington DC base.

"The tide is 4 kilometers away!"

"I can see them!"

On the high walls of the base, soldiers stared at the black wave with pale faces and trembling hands. "Commander Scott, the tanks… we've lost contact with all of them," a soldier reported, his voice heavy with despair.

"I see," Scott replied grimly, his eyes fixed on the horizon. He knew deploying the tanks alone was a tactical gamble, but he'd had no choice. On the open plains, the tanks were their best option to slow the horde.

But the zombie tide was far larger—and far deadlier—than he'd anticipated. "We're doomed," a soldier muttered, his grip on his rifle shaking. "If the tanks couldn't stop them, how are we supposed to hold them off?"

Boom! Boom! Boom!

Artillery continued to pound the approaching tide. Rocket trucks fired their payloads and retreated to reload, while survivors hurriedly carried ammunition to the walls. "Hold the line!" Scott roared. "Raise the first line of defense!"

At his command, a series of steel walls erupted from the ground 1.5 kilometers from the base. The walls, lined with sharp spikes, were positioned in a staggered formation, creating a crude maze designed to slow the zombies. As the horde collided with the barricades, many were impaled, their bodies writhing as they were skewered.

The defense worked, briefly halting the tide's momentum. The steel walls didn't connect, forcing the zombies to navigate through the labyrinth while under constant artillery fire. "The maze design from the old Commander is still effective," Scott muttered, his voice tinged with a sliver of hope.

But he knew this was just the beginning. Scott stared at the steel walls in the distance and let out a quiet sigh. This strategy had been devised by Wang Lei to counter speed-type zombies like super hunters. These creatures could otherwise sprint at full speed and leap directly onto the high walls of the Washington DC base.

Although the hunters could climb over the steel walls, they lost their momentum and could no longer use their sprinting speed to vault straight onto the base's defenses. "Heavy machine guns! Everyone else, prepare for battle!" Scott roared.

When the tide was within one kilometer, the order was given. This was the optimal range for heavy machine guns.

Click, click, click…

Hundreds of heavy machine guns roared to life, transforming the high walls into a relentless barrage of firepower. The bullets rained down like fiery tongues, forming an unbroken wall of destruction aimed at the advancing tide.

"Roar——!" Zombies dropped in droves, their bodies riddled with bullets. No one could count how many had been killed. The soldiers only knew that the numbers seemed endless. More zombies surged forward, trampling over the corpses of their fallen.

The carnage was overwhelming. The three-to-four-meter-high steel walls were quickly buried under mountains of zombie corpses, forming natural ramps that allowed the tide to move faster. Without the steel walls slowing them down, the zombies charged through, advancing rapidly toward the base. "We're finished…" Scott muttered, despair flickering in his eyes. Was the nuclear option the only choice left?

Just then, the distant roar of engines broke through the chaos.

"A plane! A plane's coming!"

"Is it our air support?"

"No… that's not one of ours!"

The soldiers watched in confusion as a massive transport plane descended through the clouds, its rear cabin door opening mid-flight. There, standing in the doorway, was a group of massive figures. "Comrades!" Andre's booming voice echoed. "For humanity!"

"Ula——!" they roared in unison. Then, without hesitation, they leapt from the plane—without parachutes.

"Are they insane?!" The sight of Andre and his team jumping from such a height left the soldiers on the walls speechless. The transport plane was flying at over 100 meters—falling from that height without a parachute should have been fatal. To make matters worse, the ground below was teeming with zombies.

Scott was the first to understand. "They're mutants!" he realized. "Cover them! Clear a landing zone!" he shouted immediately. Following his order, the soldiers unleashed a torrent of firepower, mowing down zombies below the falling fur bears.

In mid-air, Andre and his team began to transform. Their bodies shifted rapidly, undergoing an atavistic change. Thick fur sprouted, their already muscular frames expanding like balloons. By the time they hit the ground, they were no longer human.

Andre landed as a five-meter-long Siberian tiger. The others—six giant bears and three prairie gray wolves—stood three to four meters tall, their forms exuding raw power. "Roar——!" Andre's roar shook the battlefield as he lunged into the horde.

With a swipe of his massive claws, he slammed a super hunter into the ground, tearing it apart. His tail whipped through the air, sending raiders flying like ragdolls, their bones shattering on impact. "Comrades! Form a defensive line!" Andre bellowed, his deep voice cutting through the chaos.

"Ula——!" Although the other shifters couldn't speak, they retained enough intelligence to follow Andre's commands.
