"There are more and more of them, and now the whole city is full of them, the city has fallen, the troops who came to the rescue have been killed, and the area has been completely cordoned off to prevent that thing from escaping. And our research is still at a loss. ”

"The situation is getting worse and worse, after the mutation it no longer has natural enemies, and its strong reproductive ability and vitality make it the master of the creatures of this land. More and more people were being killed, the city was full of blood and dead people's corpses, and the screams of people dying were echoing in my ears all day long, and I didn't dare to stand by the window and look at the city outside. The good news is that we've identified the mutated genes in our blood, but we don't have a clue about how to fix them. ”

"The research is going well, but they are also growing and multiplying and increasing their numbers. For some reason, I feel like the city is becoming lifeless little by little. Xiao Li uses a telescope to observe the city every day, and he says he hasn't seen anyone appear outside in a long time. Even if people were to hide in their homes, it would not be possible that no one would show up like they are now, right? I'm a little uneasy."

"The research has made a major breakthrough, we have found the direction of modifying the genes, according to our analysis, the mutation caused by that drug is to increase the male hormones in their bodies dozens of times, thereby increasing the overall attack power, and we only need to start from this aspect, through estrogen to balance the male hormones, we can make them back to the original state. However, I haven't been able to contact my family for several days and I'm feeling worse and worse."

"Demons! They are demons! The whole city and the whole city have been treated! I'm going to have to figure out how to get rid of them! Definitely"

"The research is still ongoing, the whole lab is a dead scene, everyone is just doing the research mechanically, we have developed a drug that synthesizes male hormones, but we have not yet found a way to make the rapid fusion of estrogen and male hormones. Now I'm afraid that the whole city is the only one left alive, maybe because of our high position, that kind of thing hasn't come here yet. I happened to glance outside today, and my eyes were full of black and red, and the whole city was covered with dried blood. Maybe tomorrow it will be our turn."

"We closed the building, only on the third floor and on the rooftop, and there was less and less food left, so we sent a few people out today to look for food, and Xiao Li was among them. I was assigned to know what was going on with them through a telescope, and right in front of my eyes, I watched them being torn to shreds by that thing. Is this revenge? We created what we wanted to kill them, but gave them the ability to kill us. It's raining, hopefully the rain will wash away all the blood and sin in this city."

"We redirected our research in the hope of focusing on increasing the use of catalysis so that it could work quickly, but now we have found that we can use electromagnetic waves as catalysts. Hopefully it will be successful."

"The research was a success! We have found the frequency of electromagnetic waves that can be catalysts! Only now, the supply of electricity is insufficient, except for the laboratory, all the power equipment has been turned off by us, and we have carefully calculated the amount of electricity left, which is only enough for us to play a catalytic electromagnetic wave. The spraying of the agent requires us to enter the operating system in the city center to carry out it, where the preparation is completed, and then the operation authority is transferred to the research room through the program, and finally the research room controls the splashing and propagation of the agent and electromagnetic waves at the same time. Only in this way can their genes be successfully corrected. It's just that there is only one key to the operation authority, how can we take it to the city center and bring it back?"

"Today is a bad day, the doctor himself went to the city center with the key to operate the authority, everything seemed to be going smoothly before, storing the potions, transferring the permissions. We thought we were going to succeed at last, to end the domination of these demons. However, on the way back, the doctor, like Xiao Li, was torn to shreds. The key is lost, maybe they have eaten it by mistake, and the key on the tracker that shows the permission to operate is always moving, but we can only look at the tracker and have nothing else to do. Do you really have to despair?"

"The food had been eaten and the location of the keys had paused for a long time without changing again. There were only three of us left, and the other two decided to go tomorrow to find the key, leaving me as the last recorder. They had gone to rest and smiled before going to bed and asked me to wish them good luck good luck they needed more good luck"

"Good fortune didn't bless them, and so did they, maybe I would have guessed that there would be such a day, right? In the last moment of despair, I was the only one left. I've never been a strong man, and I don't think it's my responsibility to save the masses, so let me run away. By the time I finish writing these words, I'll jump from here, my body will be eaten by the demons, but my soul will finally be freed. The night sky is beautiful, I haven't seen it in a long time. I remember that when that medicine first appeared, it appeared on the front page of the newspaper, and the people of the whole city laughed and laughed, and used it as an after-dinner conversation to find them to experiment again and again. However, after the mutation appeared, it seemed that the roles were reversed, and we became the ones who were in control, and they dominated our lives. It turns out that this is what it feels like to be dominated, but I didn't expect that people claim to be the primates of all things, but in fact, the stronger creatures on the other side are so vulnerable. Okay, that's all, I'll leave this diary here, if anyone can see it, next to it is the electromagnetic wave transmitter and the tracker of the operation permission key, all the programs are set up, as long as you find the operation permission key, turn on the power and complete everything, I hope you can destroy those demons. I've always been an atheist, believing only in science and not any religion. However, at this time, whether it is the gods, gods or Buddhas, I hope that you will bless this city and bless one day, it will be able to come out of the abyss. Well, goodbye. ”

"No, that's all there is to this diary." I turned to the next page, which was no longer written, and turned back to the last page, the paper where the words "Goodbye" were written slightly puffed and wrinkled, and I could feel the roughness of the bulge as my fingers slid over it. I know it's because there was once a tear here, a tear of despair, relief and perhaps undying hope before a person died.

I was born with a sensitivity to words, which is why I chose home as a profession, and what was written in this diary actually made me feel a sense of empathy for the owner of the handwriting, and it seemed that I also felt the despair, helplessness and expectation in my heart.

However, what I have to think about now is how to live, so I can only suppress this feeling in the depths of my heart and think rationally about the current situation.

"That's what we're talking about, this big machine is the emitter of electromagnetic waves, and the tracking device is this little cube?" As I spoke, I picked up a rectangular machine on the side. It's about the size of the palm of my hand, and it's not very heavy, so I can easily pick it up with one hand.

"Looks like so." Wolf Fang reached out and motioned for me to hand him the device in my hand, "From this diary, I finally found some useful clues. ”

Lin Ya walked around the electromagnetic wave transmitter and said, "I took a look, this transmitter is connected to a generator, it should be able to work after turning on the generator." And there's a console on top of this stirring, and there's a strange groove on it, which may be where the permission key is placed. ”

Hearing this, Wolf Tooth walked towards the location pointed by Lin Ya, and I also followed to check, and sure enough, I found that there was a large glass operation panel on the other side of the machine, and next to the panel was a hexagonal groove, which should be like what Lin Ya said, where the permission key was placed.

Wolf Fang took out the notebook in which the map was recorded, covered one of the pages on the groove, pressed it down lightly, and engraved the shape of the groove on the paper, and recorded the shape of the key in this way, and when he had done all this, he turned to us and said.

He said, "Let's analyze this diary first, it contains a lot of clues. I'll start with my summary and analysis, and then you'll see what I'm missing. ”

"yes, okay." I nodded in agreement, thinking back to what I had just seen in my diary, comparing it with the clues that the wolf fangs had raised.

"First of all, the exact information that can be obtained from the diary. Regarding that unknown animal, its reproductive ability is very strong, the number should be very large, it should be very weak, there are natural enemies in the city, and the reason why it has the current situation is because it has taken a certain drug, so it has mutated, and after mutation, it feeds on humans and humans. This mutation is caused by an increase in male hormones in the body, and this mutation can be reversed if estrogen is combined, and this machine emits electromagnetic waves that have a catalytic effect. Wolf Fang summarized the diary and recorded it in his little notebook, and when he finished speaking, he asked, "Is there anything else to summarize?" ”

Lin Ya looked at the wolf's tooth notebook, paused for a few seconds as if he was thinking, then shook his head and said, "No, I think of so much." ”

After hearing Lin Ya say that there was no, the wolf tooth nodded, and was ready to continue, "Okay, then I'll continue to say"

"Wait a minute." I interrupted Wolf Fang's words, gathered my thoughts, and said, "I think there are still some things that need attention, such as one, what is the potion that the animal eats?" Why do humans feed them this? There are no more than two kinds of medicine, the medicine that cures the disease and the poison. Based on the previous attitudes towards this animal described in the diary, I think it is more likely that it is poison. And there are only two situations in which humans want to kill an animal, one is that it is beneficial to humans and people need to use its value, and the second is that it harms the interests of humans. According to the diary, it should be the latter. In other words, this is a pest animal that will appear in cities and hinder human life, and we will choose to kill it in ordinary times, and it is likely that poisoning it is a common way. ”

As I was talking, I noticed that the wolf fang was staring at me expressionlessly, and I was suddenly startled, and the words I had thought of were suddenly disrupted, and I looked at him and asked a little crampedly, "What's wrong?" Am I not right? ”

He still didn't speak, just looked at me fixedly and was silent, and after a few seconds, he suddenly smiled after seeing that my heart was hairy, "No, you're right, go on." ”

The smile came so suddenly, it was different from the usual smirk or ridicule, but a smile that came from the heart. I was suddenly shaken unguarded, and after my heart was confused, I hurriedly calmed down, no longer thinking about what the smile meant, and reorganized my thoughts and spoke again.

"Then I'll continue, two"
