Upon hearing this, the senior executives nodded in agreement, realizing that this was an urgent and pressing decision, and they quickly set about taking action.

The room was filled with urgent yet orderly commands as various departments began to work closely together to upgrade and improve the defense measures as quickly as possible.

Meanwhile, inside the shelter, people gradually sensed the atmosphere of urgency.

They exchanged urgent notices from higher command, and the entire shelter was shrouded in a tense and gloomy atmosphere filled with terrifying mutated creatures.

This is the shelter's loudspeaker going off, announcing the message over and over again.

[Attention everyone in the shelter! There's an influx of mutated animals outside. Please keep your doors and windows closed and do not go outside...]

The crowd in the hall continued to grow. As the announcements were broadcast repeatedly, people looked worried and discussed countermeasures among themselves.

"How could there suddenly be a surge of mutated animals?"

"Can the terrifying defenses of those behemoths' bases really help them?"

"My God, this is terrifying! It's only been a little over six months since the natural disaster, and there's already a mutated animal tide?"

"That mutated animal is so huge, dozens of ordinary people couldn't defeat just one. What should we do?!"

While a group of refugees were discussing the matter, the official shelter's armory was opened, and emergency-prepared firearms were inspected and distributed to each soldier.

"Quickly, quickly, all soldiers who have received weapons, go to the protective wall to guard it."

"yes!"

The operation began, and the higher-ups quickly organized a small team. Dressed in heavy protective suits and armed with firearms, they went outside the shelter to fight the mutated animals.

Their mission is to quickly eliminate the invading mutated animals to relieve pressure within the shelter.

"One team has reached inside the protective wall and has begun to seal off the defensive line."

The second team has arrived and the defensive line has been sealed off.

"The three teams have arrived and can begin firing."

Team four, team five, team six...

Seeing all the troops slowly taking their positions, the officer didn't have time to wait and hurriedly shouted:

"What are you waiting for? Fire!"

"Give them a good beating!"

No sooner had the instructor finished speaking than machine guns, rocket launchers, and heavy machinery unleashed their full firepower.

"Yes, sir!"

"Launch!"

"Da da da da da..."

"Bang bang bang bang bang bang..."

"Boom boom boom boom~"

As artillery fire rained down on the outside of the protective wall, the screams and roars of mutated animals echoed in the distance.

"Awoo~"

"Sizzle~"

"Roar~"

"Squeak squeak~"

The roars of various mutated animals rang out, growing ever closer: mutated wolves, mutated rats, mutated scorpions, mutated snakes, mutated tigers, mutated wild boars, mutated lions, mutated ants… a diverse array of countless species.

Nowadays, most large mutated animals have mutated, but smaller species such as mosquitoes, locusts, leeches, earthworms, bees, and ants have not yet fully mutated.

After the extreme cold ends, a new round of enhancement will begin, and all animals will mutate and become stronger, with no one spared.

Mutant animals rarely turn into zombies, but some old, weak, sick, or disabled ones may.

Chaos reigned inside the official shelter in Yong'an City, with people hiding in fear in every corner.

They could hear the roars of various mutated animals outside the protective wall, getting closer and more intense.

A terrifying sense of oppression enveloped everyone.

"How can there be so many sounds of mutated animals?"

"This is too much! Can we really hold this place?"

"I trust the soldiers in our official shelter; they will protect us."

"The disparity in strength between the two sides is too great. Let's find a place to hide!"

Suddenly, a powerful force slammed into the protective wall, producing a loud "boom boom boom boom".

The sturdy protective wall was shaken to the point of collapse by the impact of the enormous object.

A giant mutated wolf and a wild boar had such a powerful impact that they smashed through a ten-meter-high protective wall in one go.

As the giant mutated wolf and mutated wild boar strode through the broken protective wall, drooling, they glared fiercely at the fleeing, screaming refugees inside.

Then, a fat mutated rat followed closely behind, followed by two mutated scorpions, a mutated snake, and even mutated tigers, wild boars, lions, and countless mutated ants.

Their sheer numbers were staggering, and their various roars mingled together, creating a truly chilling scene.

The massive tremors of the protective wall caused panic among the people trapped inside the shelter.

They realized that in a moment, this impregnable fortress would be completely breached, and they would have nowhere to escape.

The soldiers began to move, aiming their machine guns and rifles at the mutated animals outside.

"Quickly, defend this area and give the people behind time to escape."

The sound of gunfire, "rat-a-tat-tat...", instantly filled the space, creating a terrifying symphony.

The bullet struck the mutated animal's body, producing a series of muffled thuds.

"Run! The mutated animal has broken through the protective wall!"

"Aaaaaah~"

"My hand, my hand has been bitten off."

"Ah...run! The mutated animals are too ferocious!"

"Mommy...where are you...waaaaah!"

Screams and wails echoed throughout the shelter as people struggled for survival and fought desperately against attacks from mutated animals.

Some people were already bleeding profusely from being bitten by the mutated animals, while others bravely fought the enemy with rudimentary weapons, hoping to gain a glimmer of hope for survival.
