"What an unfriendly world!" Ling Yun stood in a forest with only dead branches left, frowning and looking around.

In this place, the whole sky was gray, and even the sun lost its light. The ground beneath his feet shone a strange dark red, as if it had been soaked in blood. The trees around him were completely decayed, and there was no trace of life in sight. Occasionally, you can see some buildings in the forest, but these buildings have long since been ruined, and there is no trace of human habitation.

A strong gust of wind with a pungent smell whistled past Ling Yun, and Ling Yun could even feel the trace amount of toxins in the wind. There was a palpitating atmosphere in the air, as if there were countless evil things hidden in the shadows, eyeing him in the dark. A strange roar drifted in the wind, and I don't know if it was from the bad people hidden in the shadows, or if it was formed by the wind blowing through the dead wood.

Looking at this world that seemed to have been completely reduced to hell, Ling Yun let out a sigh of relief, and an invisible talisman shield naturally appeared beside him, isolating all the surrounding filth.

"It's really a world of despair!" Ling Yun said with a sigh.

Suddenly, a strange roar sounded from Ling Yun's side, and a black figure suddenly appeared behind Ling Yun. Ling Yun's figure flashed suddenly, and in an instant, it flashed more than ten meters away and landed on the branch of an ancient tree.

"Boom-" A huge tail swept over where he had just stood.

Through the sunlight through the dead branches, Ling Yun saw the full picture of the monster that attacked him. It was a monster that was three or four meters in size. It has a tiger-like body, but it doesn't have any fur on it. There were green tendons that swirled around its body like water pipes, and the head of a creature of unknown origin was held high, and a trace of saliva continued to drip from its mouth, eroding the ground into small pits.

"This is, gastrators?" Ling Yun couldn't help but frown as he looked at this deformed creature that had unleashed a huge amount of malice at him.

"Roar—" A strange roar came from the creature's mouth, and its limbs pressed down slightly, and then it suddenly burst into its arms and pounced in the direction of Ling Yun.

With a wave of his hand, Ling Yun swept several wind blades out of his hand, tearing several huge wounds on the body of the protozoar, and knocking it to the ground. However, the protosagularis showed a strong ability to heal itself, and in just a few seconds, the wounds on its body stopped bleeding and showed faint signs of healing.

"It's really tenacious! So, what about it! Ling Yun raised his hand, and golden light escaped from his hand and scattered towards the protosagular.

Illuminated by the light of the pure world, the protogulars let out a terrible roar, and then its body began to melt rapidly, and finally disappeared into ashes.

"It seems that this method is more effective!" Ling Yun said thoughtfully.

"Forget it, let's go find a populated place first, I don't know where Ruoxi threw me to." Ling Yun's figure turned into an afterimage, flying towards the outside of the jungle. "According to Ruoxi, the current point in time should be in the ninth year of the war between humans and proto-aragut!"

About nine years ago, the world was a seemingly peaceful world with a population of more than 8 billion. However, a terrible catastrophe has occurred, and a monster has appeared in this world without warning. It is a creature that is born after a creature is infected with a terrifying virus that has a high degree of infection through the blood and can rewrite the DNA of a creature. The name of the virus is protozoan virus.

Organisms infected with the Plasma virus, whether humans, animals, or even plants, will all be transformed into Gastaroids by the virus at an alarming rate, becoming complete monsters. This monster not only has terrifying and ferocious powers, but can infect the intestinal viruses by injecting bodily fluids into other living beings, making the infected creatures animalized, and it also has a certain degree of regenerative ability.

On top of that, this creature is extremely hostile to humans, as if it were born to be hostile to humans. There are only two outcomes for humans when faced with gastrulation, one is to become the nourishment of gastrulation, and the other is to be assimilated into a member of the gastrulation. What's even more terrifying is that ordinary weapons are hardly able to deal effective damage to this creature.

Under such circumstances, an extremely terrible number of protozoa invaded the human world nine years ago, starting a world war. In the end, humanity suffered a crushing defeat, with more than ninety percent of humanity killed in the battle, and eighty percent of the territory ruled by humans was also taken by protozoa. The remaining one-tenth of humanity could only be scattered and hid in an area surrounded by huge black stone tablets, and engaged in a tug-of-war with the aragut for nine years.

The substance that makes up this huge black stele is a metal unique to this world, called holmium. This metal can effectively stifle the regenerative system of gastroids, and can emit a weak magnetic field to weaken the living surname of gastroid viruses.

It is precisely because of the existence of this metal that humans survive the frenzied attacks of protozoa, and in this way, they have established the last survival base of human beings. It is also because of the existence of this metal that humans have the ability to fight against the protozoa, and they still dream of regaining the lost land.

However, holmium is not invincible, and there is also the greatest enemy of mankind in this world - the ultimate protozoa. They are large and extremely powerful, and are immune to the magnetic fields emitted by holmium metal. There are a total of 11 such horrific beings, named after the twelve zodiac belts.

Taurus and Virgo have been suffocated in the war between humans and protozoa, and now there are nine Stage Five roaming around the world. Wherever these guys appear, it's the end of humanity there.

"Huh? Is that a megalith? It seems that we have found the location of the human city! Ling Yun's figure landed on a dead branch and looked ahead.

In the distance, there is a huge black stone monument that stands on the ground, much higher than the average mountain. Among these huge stone monuments, there is a city.

"Now that you've found the city, let's go there and see it, I don't know what that place is, but if it's the starting point of the plot, Tokyo City, then it's fun!" The corners of Ling Yun's mouth curled into a smile, and then his body turned into an afterimage and flew away in the direction of the city.
