Hi everyone! I decided to give my imagination some working, and this is what I came up with! Pairings and everything isn't defined yet, if you ask. And I would like a Beta Reader for this story too. Well, now, enjoy the chapter!

I woke up in my home, thinking about how my life was going to change right now. I was going to be studying now in a university, exactly the medicine career. Long time ago was when I could spend the time playing videogames with friends, or going to judo and softcombat. Now, I was starting a new life as a university student and I would have to spend much time in books and learning how to be a doctor. I sighed, as I got up from my bed, going to the bathroom to freshen myself to the start of my day, my first day going to the university.

My reflection appeared in the mirror after I took a shower, showing me a teenager bar man body of eighteen years old, lean but not muscled; at least I wasn't a stick like others, while my dark hair was pulled to the back of my head. My skin was a bit pale, and my dark brown eyes looked back at me with the help of the mirror. I had removed any kind of facial hair from my face with a good shave, and some body hair was still present in my body but not much. Definitely, the typical body of a teenager going to adulthood. After I finished drying my body and hair, I dressed up with some jeans and a shirt, along with trainers.

When I finished my preparations; including taking breakfast and preparing my bag with a first aid kit, some books, notebooks and writing materials, along with my mp4 with music and my mobile phone, I went out of my house, going to the bus stop to wait for it. I was nervous, as I didn't know how I was going to get along with my future classmates, or if the teachers were going to be good or bad. I sighed, trying to relax while listening to my music, making it a bit louder to abstract myself of the noises of the street, but a noise was starting to get louder and louder, so I turned to see what was making that noise.

Just in time to see how the bus was out of control and about to run over me.

I couldn't move, I couldn't even think before I felt the impact on my body and everything turned into darkness, but it was strange. It was supposed to hurt… but I felt different, like I was falling into nothing, and being pulled at the same time to another place. Before I could try to guess what was happening, I fell to the ground.

I could hear noises, but one of them wasn't exactly… human. I started to get up, still with my eyes closed, until I heard a shout. – "Move out!" – It said, with the voice of a man. I opened my eyes, and I could see a monster, a really big praying mantis with an unnatural glow and colour, with its legs with edge like swords… So I made the choice of an intelligent person would do nine out of ten times.

I started to run while screaming, making it very clear that I was being chased by the monster. I could see that now I was in a courtyard of a medieval fort in ruins, along with some men that were dressed like medieval bandits and some armoured men with longswords. But as I was running, one of those bandits with an axe tried to put himself in the middle of my path, swinging the axe to chop me like some wood. I ducked and grabbed him, toppling him over my head and directly in the path of the monster before I started running again. I started to hear some screams, from the bandit being devoured by the monster.

Soon, the fight reduced to the monster and the armoured men, along with myself as a bait as I could still see how it kept chasing me. Then, I could listen some gongs, as two of those armoured men made those gongs make the sound, while the rest started to attack the monster with their swords, liberating me from being the bait. – "Make yourself useful and ring the bell!" – One of those men shouted, the same voice as before. I nodded, as I started to look for a bell, and I could see one. I ran towards it, and when I reached it, I started to ring it like my life depended on it, wishing it made something to that monster.

Soon as I started to do that, it seemed to weaken that monster, and the armed men started to mince it like it was nothing. They were experienced and avoided the most dangerous moves of that monster. After a while the monster fell. I breathed relief seeing it dead, but then, something happened in form of a woman appearing out of nowhere; like she teleported herself, wounded and saying that she was overpowered. Some men started to tend to her, and deciding I wasn't going to be useful here, I accompanied the rest, rushing toward some kind of basement with a laboratory and a man with an arrow lodged in his chest along another with white hair tending to him.

- "Resist!" – One of the men shouted, while the others were trying to find some kind of essence. But in this case, I rushed quickly while grabbing my bag and the first aid kit I had in there. Some of the men started to threaten me now with their weapons, but I couldn't care less right now.

- "If you want him to live, let me treat him!" – I shouted, while I continued grabbing things, like alcohol to clean the wound and other things. I was going to do some operation and without previous experience, but a life was in danger right now, and as a future doctor I needed to do everything I could.

- "Too late… he is dead." – The man who was tending the wounded said with grave tone. I shook my head, not giving myself the despair that it would come to that. Maybe they were stuck in the medieval era, but now I was from an era that the medicine was really advanced, and if the theory was correct...

- "Then let's bring him back!" – I said, putting my hands on the arrow and removed the long part, only staying inside the arrow head, and started to pump his heart with my hands in a form of resurrection technique to restart the heart and mixing it with artificial breathing. The rest of the people here were looking at me like I had grown two heads, but then I felt the heartbeat of the man, and his chest rising and falling again

- "Yes! His heart is working again." – I shouted, making the people in the room rush to check on him, but luckily, the man who had white hair made the rest to give me space. Meanwhile, I used the alcohol to clean my tools for the operation. I had to admit that my first kid aid was more like a surgeon equipment; as I used all my allowance and life savings to purchase everything a surgeon would wish for; that was portable of course.

When I finished, I approached the wound, and to the gasp of the people there, I made an incision to let me see how the insides of the man was. I put the tools that made it stay open, before taking a look. The arrow head was lodged inside the second and third rib, missing the heart by mere inches. Some lacerations were made, but nothing too bad, and there wasn't any cracked ribs.

- "Stop right there this moment!" – A man bellowed, but I caught the forceps and approached the arrow head, but then the man started to move, possibly in pain. I couldn't approach it while it moved.

- "If you want him to live, help me then! I have to remove the arrow head from there or it could damage him more, and then I can't save him! Make him stay put!" – I shouted, and the man with white hair and another grabbed the legs and arms, making him stay put. I approached again and with a simple but delicate move, I grabbed with the forceps the arrow head and removed it, before suturing the wounds. Then, I closed the incision after removing everything. I sighed, feeling exhausted.

- "How is he?" – One of the men asked, probably the leader as how the others looked at him. Everyone seemed seasoned in fights, with scars in their body to make everyone believe it. I sighed, while trying to fight the needs of my body to rest. Too much was happening and I knew nothing.

- "In theory he will recover. Just check how he is once in a while, and when he wakes up make sure he takes it easy, and he don't touch the stiches. If something happens, tell me." – I said, while cleaning my tools and putting everything in my bag again. I felt really tired, but if someone was hurt it would be better I treated it right now before thinking on sleeping. I tried to get up, only for my legs to fail in that task, making one of the men grab me before I met with the floor head first.

- "Rest for the moment, we will speak when we have enough rest." – He said, and I couldn't avoid closing my eyes and falling asleep in a place that I didn't knew anything about, along people who I didn't meet before.

Sooner than I thought, I woke up with some voices in the place, like they were discussing something. Opening my eyes, I could see how the man with white hair and the supposed leader were discussing something next to a fire for cooking something. As soon as I started to move, their eyes were on me, and I could see how they were different… more animalistic or something like that. I shook my head trying to think, but finally I let that matter rest.

- "How are you?" – The supposed leader asked, while I started to go to them. I could say that my clothes were battered and possibly would need to go to the laundry… if there was any laundry in this time.

- "A bit sore… and without really knowing what happened. You could say that I am still in shock or not processing everything, otherwise I don't know how the heck I am calm right now." – I said, and sat when they made space for me next to the fire. They looked at me with curiosity.

- "I am Vesemir, and he is Geralt. You are in Kaer Morhen, where we took people for Witcher training. I am grateful that you saved Leo from death hands." – The leader said, and the one with white hair nodded at the mention of his name. I smiled a bit at the thought of saving a life, even when I was more confused than anything right now.

- "It wasn't a problem, I was training to be a medic so saving the life of him was my job. Ah, my name is John, by the way." – I said, as I remembered then the operation I made in an instant there… It was something that now frightened me to no end. What would have happened if I did something wrong? That man would be dead if I made a mistake… This is what every medic had to fight?

- "Those methods you used to heal him were… strange." – Geralt said, looking at me. Those animalistic eyes were really getting into my nerves, but I supposed that it was something I was going to get used to.

- "Well, they are unorthodox, but effective. And don't think I could do something like I did with Leo every time, I have to get lucky and a time limit at that." – I said, making them looking at me expectantly, like waiting for answers. I sighed… When did I started to teach them medicine?

- "When one heart stops, its blood stops running through its body. The blood contains some parts of the air we breathe each time, sending those parts to our muscles, and our brain. Stopping that flow makes it similar to suffer from drowning, making the brain lose functions over time. If the circulation of blood continue its course in the time limit of half an hour, it's good, but closer to the time limit, less chances and if it functions, probably with problems." – I explained, and I was glad that they followed my explanation with ease. It was an advance there, and something I rather enjoyed; normally my friends…

- "Shit, my friends… My family… What happened to them? What happened to me in my world? Am I considered dead in there? I merely disappeared or there was a body instead?" – I thought, lost in my mind as I considered every type of possibility thanks to the high quantity of fanfics I read in my computer, and each possibility was worse by the second. Luckily, I couldn't dwell too much thanks to someone calling me and a hand in front of me waving.

- "Are you alright? You seemed absentminded." – Vesemir asked, worry in his tone. I sighed, trying to remove those thoughts of my mind, but they kept coming… maybe first I have to think how can I go back to my world before trying to do anything else.

- "I am fine. Just… thinking about where I come from. The thing is… I am not from this world, and have no idea to how can I go back there since in my world magic or monster doesn't exist. Ah, and I suppose that in there I could be dead since I was run over by something." – I said quickly, and feeling nervous since probably a story like that would mean that I was crazy or something.

- "You mean… in your own world you are supposedly dead, and have no idea of how to check it or how to go back there. Did I miss something there?" – Vesemir said, and I sighed in relief, as I shook my head, to show that he didn't miss anything in that resume. Both of those men seemed now to be lost in thought.

- "Well, maybe Triss can try something, but she is still unconscious. Geralt, you know what to do, and bring some things for him too." – Vesemir said, and I looked at him, raising an eyebrow with an unasked question. Geralt nodded and got up, walking away towards a door, and closing it after he went inside.

- "We won't be staying here much time, we have to find some things these people stole us, and make them pay for that. You will accompany one of us and since our path is dangerous, you have to defend yourself, and not only throwing them to the ground." – Vesemir continued, making me gulp at the thought of killing people. It was something that I supposed it would happen, but the thought of killing… it was enough to turn my stomach sick.

- "I understand… but I don't like it." – I said, trying to relax a bit even though my body was tensed like a bowstring. Then I felt a hand in my shoulder, and I saw Vesemir making a smile, like he knew what I was thinking.

- "Don't worry. Remember that you won't be alone. And about killing another person… it becomes easy with time. And even then, you will still don't like it, but it's either you or him most of the time. Don't even doubt to make the choice of surviving yourself." – Vesemir said, before getting up and started to walk away, leaving me to watch the flames… and thinking on how the heck my life turned up like this.
