As Mark thought about it, he started remembering some bizarre moments when he was fighting the past few days. He remembered how his body reactions were quicker than how they previously were. His body was now reacting and also more flexible than before.

When he fought the zombies from a close range, he sometimes felt the sense of danger become more evident than normal and his body would react abnormally to defend against that danger. This never happened before. It would feel like his body was not in his control at that moment, making it more bizarre for him.

He then closed his eyes and opened them as he looked out of the window. It flabbergasted him when he did. Even though it was night, he could see everything clearer than before. It was like his eyes had a pair of binocular on them. His eyesight range also increased a lot. He could see a tree which was approximately 50 meters away from him.

He remembered that an average human can only see objects 20 feet away from them as clear as he did just now. His mouth went open as he thought about it. He then thought of something and closed his eyes. He tried to hear sounds.

He could hear the bugs in the surrounding grass as clear as they were right beside his ears. He opened his eyes once again and dragged a chair in the room to the window side to sit down. He started to think about the changes he felt just now.

'This is abnormal. How can I see, hear, and feel better? I developed a keen sixth sense of sorts for danger and my body now is enhanced compared to before. It is almost like I upgraded myself from before.'

'I could now practically see things almost 10x the distance an average person can see. That is a very big leap. Are these changes happening only within me or is this happening to everyone in general.' as his eyes landed on Suzie's sleeping figure.

But he shook his head and thought, 'No, that can't be right. If it happens to everyone, then why was David not able to listen earlier today? It makes no sense.' as he started to think deeper.

Something suddenly clicked, and he thought, 'It must be different for each person. The time taken for one person to become as I did just now must be different from each one. This is probably the adaptability of humans.'

'Our bodies are slowly getting adapted to the virus which caused all this. They say humans to be one of the creatures which have the most adaptability. We can adapt to any given situation as long as we give the body enough time to do so.'

He remembered something he read online about animals and human evolution and adaptability once before on the internet.

'Like the evolution of man from apes. It happened over the course of time. The external environment This is also the reason why giraffes have long necks. Giraffes were originally said to have short necks like any other creature.'

'But due to natural selection and the need for survivability, it's body started changing so it could live off eating leaves from tall trees that normal animals can't eat. Humans are also the same. People who live in extreme temperatures are more adapted to the place than normal people or people who haven't been exposed to that kind of environment.'

'Now this is happening with the virus. Our bodies are now slowly adapting to the virus and are slowly changing. It is naturally different from each person. The speed probably depends on the need of each individual.'

'So now that our bodies are adapting to the surrounding environment, the next question is how far are they going to grow or to properly say evolve. Is this going to be like one of the games where everyone gets superpowers because of this.' Mark chuckled and shook his head at the nonsensical thought he had.

'Now I wonder how much time it will take for David and Suzie to have changes in their bodies. Would it be similar or would the changes be different for each person? It would be nice if their body is quicker to adapt than normal.'

He then remembered the small cube he found earlier. Taking it out of his pocket, he held it in the moonlight to get a better view of it. He slowly started to examine the cube. It had patterns similar to the ones on his right hand. He tried to see if there was any kind of opening to it and found none.

The cube was tightly encased and couldn't be opened. He then remembered the place he found it and thought, 'How did it get there. It was inside the enormous crater-like it fell from some height. But a crater that big would only be formed if it was a meteorite, and it fell from space. Did this come from space?' playing with it.

'And also the eerie feeling the cube gave off before. It stopped coming once I took it into my hands. David also said he felt nothing when I was going inside. So was this cube giving out some sort of signals and I happen to feel them?'

'Also based on the size and number of footprints around it is very suspicious. It looked like there were a huge number of zombies in those woods, but they suddenly vanished when I went there. The footprints were especially more around the crater.'

But all these observations he made boiled down to one question, 'Are all these matched or coincidental?'

He shook all these thoughts from his head and stood up from the chair. He noticed it was almost midnight, and they had to move early tomorrow. He kept the cube back in his pockets and went to his bed. Laying on the bed, he thought, 'All the answers would probably come to light in the future.' and closed his eyes to get some sleep.
