A trace of white air emerged from a corpse of a rabbit-like creature and was absorbed into Wang Yuan. He slightly sensed the white air outside his body. Wang Yuan estimated how long the white air could last and set off again.

Along the way, Wang Yuan made many new discoveries.

The most important one is the test of thirteen crows.

Not beyond Wang Yuan's expectations, the body fluids of these thirteen crows still contain the mutated bacteria. They are the thirteen pathogens. As long as the animal's wound touches the body fluids of the crow, it will be infected by the bacteria.

During the journey, he kept instructing crows to capture other animals for bacterial infection experiments. So far, it has been conducted hundreds of times.

After these animals are infected by bacteria, they will die within half an hour to a day, which may be due to insufficient experimental products.

During these days, Wang Yuan also discovered that a large number of creatures different from the earth were not enough and had not escaped the hunting of thirteen mutant crows. They carried deadly bacteria on them, and as long as they were pecked at them, they would not be able to escape death.

However, the manifestations of these experimental subjects after infection with pathogens are also different. The death time of mammals after infection is similar to that of Wang Yuan. The experimental subjects include herbivores similar to rabbits, carnivores similar to tigers, and primates similar to monkeys.

They first have nosebleeds, weak limbs, and then vomit and diarrhea, and finally fall to the ground and die. The whole process lasts about half an hour to an hour. Omnivorous animals generally have to last longer.

The insects are even more unbearable. After touching the crow's feces, they will die if they struggle for more than ten minutes. The amount of white air provided is pitiful. Therefore, Wang Yuan has completely given up his research on insects.

Only birds have the strongest resistance to this mutant bacteria. After more than ten birds were infected with the germs, they survived for an average of eighteen hours. The longest bird even had a mutation similar to a crow. The feathers all over their bodies fell off and new feathers began to grow. Unfortunately, they died at 27 hours and the mutation failed.

Wang Yuan died in just a few minutes, mainly because of the internal reasons such as multiple bacteria attacks and various environmental factors in the other world. Now the bacteria on the crow have undergone several mutations, and it is no longer the kind of killing Wang Yuan.

Even this bacteria is still mutating now. I don’t know if it is an illusion, but Wang Yuan can vaguely sense the existence of these bacteria.

"The white breath is consumed too quickly." Wang Yuan stayed in a cave. Now it was a sunny sky outside. The autumn sun was not fierce. However, once Wang Yuan appeared in the sun, the white air on his body would melt quickly. Now there is not much white air, and Wang Yuan did not intend to waste it.

The statement that ghosts would not appear in the daytime in the previous life still has a certain theoretical basis. According to Wang Yuan’s conjecture, these white qi play a role in the body, so they can protect their souls.

Thirteen crows kept flying out to capture animals and brought them back to the cave. The animals infected with bacteria struggled in the cave for a while and then died. Widths of white air rose from their bodies to make up for the loss of white air.

The crow also kept providing the cool breath. Finally, Wang Yuan felt that his soul body was a little more complete. He felt that he was just a leaky balloon, constantly using things to stuff the gaps so that the air inside would not go away.

According to metaphor, his body is the balloon, and his soul body is the air inside. Now that the balloon has been broken, most of the air inside has disappeared, so he constantly uses other things to preserve the gas.

Strictly speaking, he is no longer the same person as he was a human before. Even part of his soul comes from the supply of crows. He is just an incomplete remnant soul, even though he inherited most of Wang Yuan's memories and soul.

"I need a stable white gas supply field. If possible, I need more crows to provide more breath to make up for my soul body." Wang Yuan thought that although the thirteen mutant crows were always providing cool breath, they were far from enough.

"Maybe after replenishing the soul body, I will no longer have to worry about the exhaustion of white energy and the soul body being exposed."

"Winter will soon begin. Although I don't have to consider the temperature, the crows need it."

"The bacteria are still mutating. Maybe when these thirteen crows will die due to the mutating of the bacteria."

"Once the crows die, without them helping to capture creatures and replenish white air, the only way to completely die out is to wait for me."

"This requires finding smart creatures as soon as possible. Only in this way can I develop my power in an organized manner." Wang Yuan stayed in the cave and could not walk, so he could only keep thinking about how to go in the future.

He felt a strong sense of urgency in his heart, because he was really on the line of death at all times. If he didn't pay attention, he would completely perish, and this time there would be nothing left.

The sky gradually darkened, and Wang Yuan set out again. Thirteen crows flew around to explore the path, looking for traces of human beings. Wang Yuan walked forward lightly. He had a premonition that once he found human beings, many of the problems he faced now could be solved.

...

"Comoros, be careful." A bearded uncle carefully used a dagger to lift the spider on the shoulder of a young man in front of him, and then stepped on him to death with one kick.

"Thank you, Uncle Dax." The young man called Comoros is only fourteen or fifteen years old, with some fear remaining on his tender face, and he hurriedly thanked the bearded man.

"Your thanks is left to Menas. I don't know if she is watching us. It has been three days since we entered the mountain, but we have only had this little prey." Dax, the bearded man, took back his dagger, touched his beard and said sighing. Menas was the goddess of doom that they believed in by the Cauchy people.

The village is not enough food, and it has to deal with the annoying Kents. This time, this time, the hunting team is formed to bring back some food for the winter and help the village survive this winter.

"Ahhhh..." A strange voice sounded, and a slightly huge crow fell on the branches, tilting his head to look at the team below.

"Damn, the believers of Negri, it turns out that they are the ominous things you brought." The hunting team saw the crow standing on the branches and frowned. In the words of the Cauchy, Negri had the meaning of dirty, disease, darkness, ominousness, and it was also the name of a god. Because the crow was pitch black and had ugly calls and corruption-eating characteristics, it was generally called the crow.

In the legend, all the crows believed in this god named Negri, and continued to spread diseases and ominousness for Him.

The bearded Dak pulled the bowstring and was about to shoot when he found that the Nag immediately flapped his wings and flew away.
