The massive mutations and deaths of marine algae are adding fuel to the fire of the already dire living conditions for humans.

Seventy percent of the Earth's oxygen is produced by photosynthesis in marine algae, making algae the most important source of oxygen. However, with increasing marine pollution, the reserves of these algae are rapidly decreasing due to nuclear contamination and mutated organisms.

Even in M ​​City, Lu Sheng and the others could clearly feel the decrease in the oxygen content of the air.

As the oxygen content in the air becomes increasingly thin, many people are experiencing shortness of breath, dizziness, and tinnitus.

A large number of refugees fled to M City. While Lu Sheng increased manpower to resettle the population, the weapons workshop was operating at full capacity, 24 hours a day.

After half a month of accumulation, estimating that they had enough weapons to ensure that each member of the security team had one plus a spare, Lu Sheng and his team finally decided to fight against the harsh environment.

This is a struggle between humanity and nature, a battle that is closely related to everyone's survival, and no one can stand aside.

…

A moist, salty sea breeze blew by.

Xu Yi piloted a helicopter carrying Lu Sheng and others across hundreds of kilometers to the outermost edge of the human defense line.

The Yangfan base is still struggling to stay afloat, awaiting rescue from M City.

The plane landed on the temporary helipad at Yangfan Base, but no one could spare the time to greet it; everyone was engaged in a life-or-death struggle against the natural disaster.

Outside the stainless steel fence, countless enormous figures stared menacingly at the security team inside.

Pairs of grayish-white eyes, corrupted by the zombie virus, remained motionless, and the air was filled with the stench of rotten fish and shrimp.

Some monsters have merged with zombies; a shark has half a zombie's body on its head, or a bald zombie head emerges from a hermit crab's shell.

The scene was both horrifying and disgusting, making one feel nauseous.

These marine creatures used to be readily available ingredients in supermarket aquariums, but now the roles have reversed, and humans have become fresh and delicious food in their eyes.

Faced with the relentless bombardment from the outside, the fence was finally breached by a lobster's claw.

Upon seeing this, an ice-type ability user immediately rushed over and used all his abilities to block the hole with ice, while pressing his body against the ice.

Due to lack of oxygen, the man's face turned red and then purple, and his ten fingers swelled up like small radishes.

Several giant crabs rammed into the fence like tanks, their huge claws like chainsaws, easily cutting the stainless steel fence into countless holes.

Countless tentacles and fins reached in from the gaps, quickly cutting several people.

Someone pulled out a sharp dagger and stabbed it at the tentacles and fins, but the blades only made a scraping sound as they rubbed against the hard skin, and did not cause any damage at all!

This harmless attack only enraged the monsters.

A thick, slippery tentacle quickly wrapped around and tightly bound the young man who had just swung his knife.

The enormous suction cups instantly adhered to his entire body, sucking him down to skin and bones in a second.

Lu Sheng stepped out of the cabin and witnessed this horrifying scene. He immediately waved his hand and released a sharp blade of energy.

The air blade severed the tentacle in mid-air, and a thick, putrid, salty liquid immediately sprayed everywhere.

The young man, who was on the verge of death, finally broke free of his restraints and rolled to the ground, looking in a daze at the dashing young woman in the distance.

Is this heaven?

"So the angel was a girl...and she even wore red sneakers..."
