I had to edit some parts of the 'recording' they found, because the original was stupid xD But there's no big difference in the original, I hope you like this one more. R&R It will make my day ;)

We walked outside the safe room to continue our walking to the Laboratory that was at the limits of the city. I remember that the laboratory had strict rules, and would never let anybody pass, unless you were a very specialized scientist or a doctor, like Tsunade.

She once told me that, to enter the place, you must have at least, 20 years of experience, I only had 1. Oh well, 19 to go!

I managed to get the code for entering, long time ago, Tsunade let her pin in my desk, I had to save it for later, and I still have it, luckily, I wrote the number in my phone.

"Sakura, we are almost there, do you have the code?" Neji asked

"Yep!" I smiled. Neji smiled back and walked towards me. I felt my cheeks go hotter than usual, and I believed a red mark appeared in my face. He chuckled for an instant, and kept on walking.

The trees seemed less and less, by the time, the Laboratory was clearly visible. A white big building, slightly damaged, like it was abandoned from a very long time. We didn't doubt that zombies already bitten the most of those person and were converted. The path to the laboratory was mostly blocked and impossible to walk through it.

"Great! How are we supposed to walk through it!" Kari cried "What we needed"

"We could go around it, Kari" Sasuke whispered

"It's a good idea, but we have been walking all this distance, we should try this path before going" Neji interrupted him, Sasuke stared at him, with a death look. Neji didn't mind at all, he just kept on walking until arriving the blocked path. I was behind him, he put a foot on the rock, and quickly put his other foot on another rock. "Try to walk on the same rocks as I did" He ordered. I was next, my left foot stood in the same rock as his foot did, as so we went, in a few minutes we were in the entrance of the laboratory.

There was again, silence in the whole place. There were bars everywhere, only a access code would let us pass. I mentally prayed that the code I had opened the door. Taking my phone out, I typed the code quickly, without an error and pressed enter. It took few seconds while it was processing it, a click was heard in the background and the doors were opened. We passed quickly and closed the doors. We entered the building, it was cold, deserted, and silent, and everything matched perfectly like a horror movie.

I turned on my light and moved it all around the place, it was destroyed, like a temblor happened and finished everything, of course. I didn't plan to find someone here. It looked there was no electricity since I tried to turn on the lights, neither the computers that we found would work. It was…irritating.

"How are we supposed to find a thing if nothing works" I whispered, but Neji noticed.

"There has to be some papers at least, they don't work with electricity, do they?" I laughed, he smiled.

"Of course not" I responded. We walked to another room, it was as dark as this one, or probably more, I didn't notice. "This whole place is quite weird, isn't it?" I asked, everyone nodded. We kept on looking for evidence, but the place was almost as empty like the other one. No desks, no chairs, no computers, no nothing. "There has to be something in here!" I yelled.

"Don't worry, Sakura-san, I know that we will find something! We just need to keep on looking" Kari responded, I sighed and nodded.

Then, I heard a sound, like someone threw a bottle into the floor and let it break in to little pieces. We both looked to the place of origin of the sound, we were nervous now.

"What was that?" I asked. Neji looked at me and shook his head, 'I don't know' was I could read in his face. Nobody moved. They were scared? Since nobody moved, I went to the door that the sound came. My hands trembled, and my eyes became blurry, it became harder for me to put my attention on to the door, with all this dizziness, I almost felt like falling.

"It's…just a little longer…" I whispered to myself, putting my hand into the door handle and turning it to the right.

I pushed the door slowly; with a screech with it…It was empty.

"It was only a rat!" I yelled back at the group. I walked back at them, but then I heard another growl, it seemed different from the others, another zombie? When I turned…

Bump.

"SAKURA!" Neji yelled. Someone, (or something) ambushed me, I managed to keep his head away from me, but his hand were ripping my skin, Neji ran to my direction

"TAKE IT OFF ME! TAKE IT OFF ME!" I screamed in pain, my arms were now weaker than before; I already lost most of my blood. Neji quickly grabbed him from the back and shoot him. He fell and stopped moving.

"What the hell was that?" Kari ran to me with a first aid kit and covered my injures. "Was that even a zombie?"

"Yes it was" Neji moved with his feet the corpse and inspected it. "He seems to be young" He had a long greyish jacket with a hoodie, the pants were darker. His face was all full of blood, just like his hands and part of his clothes; his face had a young complex, 20's I believed. "There must be a reason why zombies are invading most of the country"

"And an antidote" I murmured. We went to the same room, now all together. "Ugh.." I growled. My arm was in PAIN right now, and I could barely move them, it was like I just broke them.

"Sakura, are you okay?" Neji asked, he was worried about me, I could hear it in his tone…Could he li-. I shook my head. Of course not! Were only teammates! He wouldn't feel anything for me, that's just ridiculous.

"No…It burns…" I responded. I groaned at the paint, of course I wouldn't be okay right now, it would take me time to regenerate my skin, eternity!

"Sakura, what do you usually do when you have a burn?" Neji asked me, like he was willing to do anything to make me feel better.

"I use ice to cool down" Neji looked down, sad. He and I knew that there would be no ice in this place. "Don't worry, I can hold the pain" I lied. It was KILLING ME! Kari looked in my bag if there was some cold water, luckily, there was. She put it on my arm and it started to feel better. And besides, the place was already cold, it would preserve the water in that state for much longer.

The room had papers and pencils all over the floor, I wanted to pick one but Neji grabbed it for me. And started reading it.

"Test Subject #245: failed to pass the exam of reconstruction of body cells." I read "Each one of the test subject's has failed miserably, we shall report this to the government" Was the government involved with this? It must had been something…important.

"Hey, I found this cassette" Sasuke spoke, with his low voice. "I thought it would be important since it's the only thing besides papers and pencils I could find" He passed it to Neji. Neji looked back at him and then nodded. "There's a cassette player over there" Sasuke pointed to the corner of the room, there was a broken table and on it, the player was found. Neji and I walked to it, putting the cassette in the entrance and clicking 'play'

At first, nothing could be heard, just some disturbance in the sound, I was going to take it out and clean it before it started. We could hear a man clearing his throat and asking if it was recording, there was another voice, who responded to the first man saying 'yes'

'My name is Dr. Arata Hisashi, I have been working in this laboratory since long time, but thing had change since that project the government asked us to do.

It was simple at first; the Government asked some state's to make a special formula that could regenerate dead cells. Our team looked for test subject's…all of them failed. We stopped at #260.

It was stressing, we needed to find the formula…but then, there was one. It was only a little kid, we decided to call him #261. We wanted to try it for one more time. We did the same exams like the other test subject's, he passed. Whenever he was cut, the cells would regenerate, without leaving a mark, like it was a new skin, we went further, more than just cut's, we cut a finger, it came out in a week. So then, we had this idea.

If his cells could regenerate the ones that are dead, we could bring back the ones that are dead. Yes, we extracted some of his blood and inserted it on some of our nearly dying subjects. It worked, everything was working, and this was one of our biggest discoveries ever. The 'revived' one acted like another normal person, he could taste, hear, feel and see. It was perfect. We announced it to other laboratories from other states and they quickly injected it to the ones who didn't have a part of his body, it also helped to cure the deft and the blind. Only New York, Texas and Philadelphia didn't have the medicament. The government congratulated us, and quickly, we were known all over the world. Our medicine was all over the planet, helping those who needed it.

But…after 3 months of having it released, our first 'healed' started having problems. He told us that sometimes he wouldn't feel, taste or see. We quickly gathered him to the laboratory and started studying him. Our best doctor, Tsunade, studied the body. She and everybody else were amazed after discovering what we found.

There were parasites eating the regenerated cells and replacing them with bad ones. We didn't know what to do, let him die or cure him. Most of the staff went with the first one, but Tsunade and I went with the last one.

Secretly, we started making an antidote; but…we didn't save him. The antidote was late when he was already dead.

We decided to bury his body in one of the cemeteries that were near the laboratory. But it didn't end that day, in the same night, our security guards were found dead, we searched in the cameras and we found the same men we buried…but now his skin was paler and his eyes were white, he looked senseless.

The next weeks, the security guards were found alive…but they were just the same like the man, skin was pale or had a greenish color, white eyes and no knowledge of doing the right thing or the wrong.

But of course, everything went worse, the infection quickly run through other states.

….It was late for everything, I couldn't do anything…the doctors of this place were infected…only I and my student were 'sane'.

We are now in the testing room, the infected are outside of this room, trying to get it.

Whoever is listening this…please…please help everyone. I must say this last thing…THERE'S NO ANTIDOTE. The only way to finish them is by 'killing' them, it could be cutting their head of shooting them…don't let them bite you, it will infect you in a matter of days…or hours.'

Then, in the recording we could hear a door breaking and a horde of zombies attacking them, the doctor and his student screamed in pain and then…died. The recording stopped in that instant

"So that's how it all started" Neji whispered. "All this time, there was infected all around us…but somehow they managed to lower the number, but one of them escaped and started infecting the others" I nodded.

After hearing the recording, I didn't want to think about anything else but finishing the infected. I wouldn't let them do whatever they want; now our only objective is 'killing' them.

We are the only hope.

Oh God, I think this chapter was the longest I ever written! Sorry if it's...boring xD I needed to add this to clear some stuff...you know, how all started? I was thinking for some days...until inspiration arrived and then...all this came.

Oh well, Review please :D
