It was almost noon, and the sky was still foggy.

In the foggy sky, the naked eye could see these many small brown particles floating, and the particles were as small as flying dust.

These small brown particles are a new type of bacteria, the bitter fruit of human beings who do not care about the environment.

From the time it first appeared, the air was filled with this new type of bacteria day and night, sucking its creatures and infecting all of them.

People, animals, and plants are all spared.

The symptoms of infection are at two extremes. Ninety percent of living beings lose their minds and become bloodthirsty and powerful after being infected. And the remaining 10 percent, although they have also become strong, can still be sane.

Half a year has passed since the initial mutation, and the people who are the only ones who are rational have gradually adapted to their current life after half a year of running-in.

Seventeen years old, Luo Yu, who has a beautiful face, is one of the lucky ones who are still sane in this very small number.

At this time, Luo Yu was hiding in a village in the countryside, in a two-story building.

The small building was already in tatters, and the broken walls were covered with dark black bloodstains, and next to the scattered bloodstains, occasionally one or two broken limbs and bones appeared, and bite marks were all over it.

Next to the broken window on the second floor, Luo Yu quietly held his breath and stared at the confrontation of people and rats downstairs.

The rat is two meters long and half a meter high, with purple stripes on its fur, red eyes, sharp and sharp teeth, and saliva dripping down from time to time on its teeth, which contains neurotoxins that can cause death from heart failure within five minutes.

The person who was holding the giant rat had the same red eyes, but his movements were a little sluggish, and the wounds on his body were all over the body, and in some places large pieces of flesh and blood had disappeared, and the white bones of Sen Sen were exposed, but he seemed to be painless and insensitive, just kept roaring at the giant rat.

After a moment's recess, the giant rat seemed to be impatient, yelled at the man, bullied forward, raised his claws and slapped the man to the ground, opened his mouth and bitten.

For a while, the sound of fighting and howling came out one after another.

After a while, it gradually quieted down, except for the sound of 'crunch, crunch', chewing.

Luo Yu was indifferent to the scene in front of him, and quietly watched as the giant rat slowly swallowed the person as food.

It's not that Luo Yu doesn't want to save it, but that person has long lost his mind, like a walking corpse, there is no point in saving or not saving, and for such a person, Luo Yu These survivors call it a zombie.

Luo Yu shook the Tang knife in his hand vigorously, which was a relic left to him by his father.

Luo Yu's father was a blacksmith who devoted his life to restoring ancient sharp weapons, and one of the most perfect works was the Tang knife in Luo Yu's hand.

As the time passed, the sound of 'crunch, crunch' was still ringing, and at the same time, the slightest gasp was mixed in, and it was obvious that the man was not dead, but still struggling weakly.

With the last swallowing sound, the giant rat burped as if it had eaten its fill.

At this moment, an extremely subtle sound appeared on the second floor where Luo Yu was.

The slight thud was followed by a 'poof' sound of a blade entering the flesh.

Luo Yu pulled out the Tang knife inserted into the giant rat's skull, bringing a large rain of blood to splash on his body, Luo Yu was indifferent to this.

At the moment when the giant rat was burped just now, Luo Yu jumped down from the second floor, and the Tang knife in his hand was forcefully inserted into the giant rat's skull.

By masking the sound of its own actions, the giant rat, which was also burping, relaxed its vigilance at that moment.

From these details, it is not difficult to see that Luo Yu has experienced a lot of such things.

Skillfully disemboweling the giant rat in order to use the flesh and blood of the giant mouse as food, as well as the round crystal that may appear in the giant rat's heart.

As soon as Luo Yu slashed the chest of the giant rat with a Tang knife, he heard footsteps, and a joking voice said: "Boy, you did a good job, Uncle Ben has taken a fancy to this mouse and the knife in your hand, if you don't want to die, put down your knife and kneel down and kowtow, you can go." ″

When Luo Yu heard the prestige, he saw a tall man with an iron rod in his hand appearing in his field of vision.

Listening to the tall man's words, Luo Yu shook his head, and at the same time stood up, the Tang knife in his hand raised and pointed at the tall man.

Seeing that Luo Yu was not interested, a trace of murderous aura appeared in the eyes of the tall man, and then he burst out. A little on his toes galloped towards Luo Yu, and the iron rod in his hand smashed into Luo Yu's left side of the head.

Luo Yu felt the 'woo, woo' sound caused by the iron rod cutting through the air, grinned and did not dodge, and stretched out his palm to grab the iron rod.

With a 'snap', the iron rod fell into Luo Yu's palm, and then Luo Yu's palm suddenly pushed backwards, and at the same time, the Tang knife in his right hand stabbed out, and the tip of the knife pointed directly at the tall man's jaw.

The tall man and Luo Yu used their strength in their hands, and the competition kept stopping, while raising his head to dodge the Tang knife.

But he didn't know that this was just Luo Yu's false move, seeing the tall man raising his head, Luo Yu's footsteps moved slightly, and he turned around and reached the back of the tall man, and the Tang knife stabbed the tall man in the back of the heart.

The tall man just raised his head and felt that something was wrong, and then felt the strength of the two of them suddenly loosen up, making the tall man's body fall backwards involuntarily.

'Poof' sounded, the Tang knife stabbed into the back of the tall man's heart, the Tang knife was extremely sharp, the blade of the knife all pierced into the tall man's body, most of the tip of the knife pierced through the chest, and the bloody blade reflected the cold light under the foggy sky.

Luo Yu pulled out the Tang knife, and the tall man twitched a few times before he lost his breath.

Watching the tall man die, Luo Yu was always expressionless, because he knew that if it was him who fell, the tall man would be like him.

In such troubled times, people's hearts have long been lost, the legal system has long been turned into nothingness, there is no trust between each other, and the best partner is the knife in each other's hands.

Luo Yu bowed deeply to the tall man's dead body, and then waved the Tang knife in his hand, the blade slashed through the tall man's chest, squatted down, stretched out his hand and probed into the tall man's body along the wound cut by the Tang knife.

A moment later, a blood-colored round crystal appeared in Luo Yu's hand, the crystal was small and only the size of an adult's little finger, and Luo Yu wiped the blood on it.

I saw that the crystals were like beads, round and flawless, and the whole showed a kind of yellow, crystal clear, like jade.

After the mutation, a round crystal will grow in the heart of many living beings, and Luo Yu's known colors are divided into five types, corresponding to five abilities.

The white color corresponds to the nerves, and the reaction can be faster and more sensitive after taking it.

The red color corresponds to the flesh, and after taking it, the muscles and bones become stronger.

The green color corresponds to the injured person, and after taking it, the injured body can heal quickly.

Black corresponds to mutations, and after taking them, the body can be sub-mutated. It's just that this mutation is good and bad, some grow claws, and some grow tails.

Yellow corresponds to weapons, which can be used to craft various weapons, or can be crushed into dust and added to steel to make steel harder.

What Luo Yu knows are these five kinds, and the abilities of these five crystals are also what Luo Yu has gradually explored for half a year and what other survivors have told him.

Seeing that it was a yellow crystal, Luo Yu put it in his pocket and turned his head towards the giant rat, and the giant rat had been disemboweled by Luo Yu, so Luo Yu just reached into the giant rat's body.

After fumbling for a while, a smile appeared on Luo Yu's face, and he withdrew his hand, and a bead the size of a pigeon's egg appeared in his palm.

Wiping the blood stain on it, a trace of shock appeared on Luo Yu's face, only to see that the color on it was not any of the five colors that Luo Yu knew.

It's colorful, colorful.
