The sea monster tide was getting closer and closer, about to break through the first line of defense, when Feng Gang took out a remote control and pressed a button.

Boom! Rumble!

All three positions were engulfed in massive explosions, with flames shooting into the sky and shockwaves turning nearby objects into dust, radiating outwards.

Large numbers of sea creatures were overturned and trampled into mincemeat by their companions that rushed up afterward.

"Well done, Third Class! I'll give you the top credit!" Luo Shan gave a thumbs up.

Li Tianyi smiled and nodded at them.

roar......

The red-eyed walrus reappeared in their sight, accompanied by hundreds of other enormous sea creatures.

"Dai Xiaohu, Dai Xiaohu!" Li Tianyi shouted.

"kill!"

Three tanks charged toward the swarm of sea monsters, followed by hundreds of soldiers.

"Damn it, what time is it? You still dare to use infantry-tank combined arms? Have you ever had your brain slammed in a door?" Li Tianyi cursed.

Dai Xiaohu immediately ordered the infantry to return to their positions and led the other two tanks in a charge.

The three tanks were lined up in a row, and the cannons and machine guns never stopped firing.

They were getting closer and closer to the tank.

Suddenly, Li Tianyi gave the order: Retreat!

Dai Xiaohu immediately carried it out.

Although their attack lasted only a short time, it inflicted considerable casualties on the sea monster horde. The red-eyed walrus and the various sea monster leaders wished they could tear them to pieces.

Li Tianyi calmly directed operations from the front lines, thwarting all their plans.

"Fu Ren, Zang Biao, heed my command!" Ma Youshan, his expression grave, carefully observed the movements of Li Tianyi and the others before suddenly shouting, "Fire!"

clatter!

Tap tap...

All kinds of weapons were firing at full power, explosions were happening everywhere, and screams and wails were constant.

The horde of sea monsters suffered extremely heavy casualties, and their corpses temporarily blocked the way. It would take at least a minute to break through completely.

Li Tianyi immediately led the team that was sniping the sea monsters to the outer shelter.

As soon as they got close, they shouted, "Full activation of the electromagnetic charging towers! Use all available electricity to turn them to ashes!"

The charging towers are frantically absorbing electricity from various power plants, their surfaces now surrounded by electric light, resembling coiled silver dragons.

"One tower is in place!"

"Second tower in position!"

......

Li Tianyi glanced at the two companies that had just retreated, turned to the Gatling gunner beside him, and roared, "I'll take over!"

The soldiers immediately made way.

They swiftly located the position where the sea monster was most likely to break through and prepared for battle.

Boom!

Piles of corpses were smashed aside by the red-eyed walrus leading a large sea beast, which came in with a menacing momentum.

"Fire!"

All defensive positions opened fire simultaneously, and apart from the massive and highly agile flying fish, they could hardly advance an inch.

"First platoon of artillery, lock onto the large sea monster!" Li Tian ordered as he fired the cannon.

"yes!"

Platoon leader Kuang Yan personally took action, sending two powerful electric currents, each several meters wide, towards the swarm of sea monsters.

The electric light was so bright that people couldn't open their eyes.

The sea monsters lost all sight and charged around haphazardly, resulting in the death or injury of their companions.

With this shift in power, the pressure on the defending troops immediately decreased.

With the addition of attacks from the other three electromagnetic charging towers, the large sea monsters surrounding the red-eyed walrus were finally cleared out.

Shortly after, Li Tianyi finished firing a burst of bullets and gave up the Gatling gun. Suddenly, it became dark above his head. He looked up and exclaimed, "Damn, it's a swarm of flying fish and an anti-aircraft matrix! Quick, quick!"

Dense laser beams fell into the school of flying fish, temporarily pinning them down 100 meters outside the protective shield.

The flying fish, having escaped unscathed, continued to accelerate and crashed into the protective shield.

"Sky-high vision, deploy the large attack drones!" Li Tianyi roared. "And the entire attack helicopter formation, deploy as well!"

Upon receiving the message, Wang Xueer quickly typed in the command and personally controlled six drones to join the melee.

At the same time, the attack helicopter formation also took off and rushed towards the Flying Fish leader.

With no pressure in the air, Li Tianyi and Ma Youshan immediately shifted their focus to the ground, frantically slaughtering the horde of sea monsters...

Half an hour later.

The red-eyed walrus could no longer withstand the attack and was struck by the electromagnetic charging tower, leaving not a trace of electricity.

It made a strange cry before it died.

The sea monsters went completely berserk, no longer focusing their attack on the city gates, but instead charging in all directions.

"Suppress! Suppress!"

"Heavy weapons, quick, quick!"

All the command posts were shouting.

clatter......

Whoosh whoosh whoosh!

Gunfire, bombing, and artillery fire never stopped.

The frenzied sea monsters fought with increasing ferocity, recklessly crashing into the laser shield.

The protective shield had just finished eliminating one batch when the second batch arrived.

As the battle raged on, the protective shield faded slightly. Li Tianyi's expression turned extremely grave as he shouted, "Wang Erzhu, unleash the energy-concentrating cannon!"

"Yes, sir!" Wang Erzhu's eyes flickered slightly as he grabbed the communicator. "Instructor, the explosive power of that thing is terrifying. We don't recommend using it unless absolutely necessary!"

Li Tianyi knew in his heart that this was a critical moment. The fact that he could say such a thing meant that this thing would definitely cause incalculable losses. "Suspend its use and switch to the air cannon!"

"Yes, execute immediately!"

When Wang Erzhu hung up the communication, he was already prepared to die and rushed towards the air cannon that was still cooling down.

"Evacuate everyone!"

The soldiers immediately retreated, only to find that he had rushed to the air cannon control panel, so they immediately stopped retreating.

"Deputy Company Commander, you have to live! The brothers still need you to command them!" said Veteran A.

"Damn it, I have no ties anyway, death will solve everything!" Old Soldier B laughed and pulled Wang Erzhu down.

Two soldiers immediately carried him away.

"Luo Changkong, how dare you steal my credit?" Wang Erzhu cursed, tears streaming down his face.

He smiled slightly, gave a military salute, and began operating the air cannon.

The surrounding air suddenly thinned out, then turned into a vacuum.

The remaining people evacuated quickly.

Luo Changkong held his breath, thinking to himself, "Comrades, brothers, Changkong is leaving first. I hope we can fight side by side again in the next life!"

He slowly pressed the launch button and fell into a deep coma...

The main position at the south gate.

The swarm of sea monsters was still attacking the protective shield, its color growing even darker. Li Tianyi's heart was in his throat, his fists clenched tightly. "Why isn't it done yet?"

call out!

An air bomb landed at the densest part of the beast horde, and the violent airflow instantly tore apart the nearby sea creatures, spreading rapidly.

In just ten seconds, a one-kilometer-wide uninhabited area appeared in the central region.

"Fix bayonets and prepare for a counterattack!" Dai Xiaohu led the Third Company's suicide squad, taking the lead in the attack.

"kill!"

As soon as the Third Company charged out, Li Tianyi ordered full cover, and the sea beasts that dared to approach them fell one after another.

"Archer squad, lock onto your targets, 45-degree angle, fire!" Isabelle stood valiantly atop the city wall, giving orders to the newly formed archer squad.

"Assassin squad, stealth!" Xiaoman gave the order and then disappeared from everyone's sight.

At the same time, the eight team members also disappeared.

Their actions provoked the survivors inside the outer shelter. An elderly man in his sixties, gripping a rifle, shouted, "These kids are fighting desperately on the front lines. Can we old bones just stand by and watch them die?"

"No, no..."

The shouts were deafening.

"Those who still have a conscience, follow me and fight your way out! Charge!" The old man was the first to rush towards the main gate.

The rest of the people immediately followed...
