Chapter 4 Underground

Naruto just sat at his bed looking at his right arm. He was trying to process what was happening, it felt so strange he could see the black fur on his lower arm and he knew it was unnatural but it didn't feel unnatural. It actually felt normal to him like he always had fur on his arm and razor sharp black claws instead of nails.

"What the hell is wrong with me." thought Naruto as he placed his normal hand on top of the fur. He felt his fur for the first time, it was strange, he could feel his own hand on top of the fur but it still felt like fur to his normal hand. Suddenly he heard a door open followed by footsteps. The footsteps stopped right outside his door.

"Who is there?" asked Naruto as he stood up.

"It's us Naruto." said Temari as Naruto noticed Temari's eyes though the metal bars on the window on the door.

"Naruto-kun." said Hinata's in a shaky voice

"Hinata." said Naruto

"Naruto we need to know if there was anyone beside us who was out on missions when the virus hit?" asked Tenten as Naruto though back to the days before in the Hokage's office when he had assigned missions to different squads.

"No most were not to assign to leave until Monday." said Naruto "And we were hit on Sunday morning."

"And we left on Saturday." said Sakura's voice

"So no one left on Saturday?" asked Ino

"A few short one day missions but not anything beyond…wait a second." said Naruto as a single mission came to mind "There is one mission I remember going out."

"Who?" asked Temari

"Kakashi-sensie, Captain Yamanto and Sai they were suppose to leave to go to the Rain to pick up an important message from one of our spies near the Earth border." said Naruto "I am not sure if they left on time but if they did they where suppose to be back by Thursday by five."

"That is in three hours." said Hinata

"The road back from the Rain is two hours away from here." said Temari "We can pick them up an hour outside the Leaf."

"Ok, Hinata, Temari and I will go out." said Tenten

"I need to stay here to get all the security systems online." said Temari

"But how will we find our way back, this place is invisible to the Byakugan." said Hinata

"There is one thing, I found this in the command center." said Temari

"What is it?" asked Naruto wondering what Temari was talking about.

"It's a map showing the location of five sand bases around the Leaf." Said Sakura

"You can use this to find your way back." said Temari

"Alright." said Tenten "Let's get going Hinata."

"But…why not send Sakura or Ino." said Hinata "I want to talk to Naruto-kun."

"Hinata you can talk to him later, Sakura and Ino need to work on the a cure." said Tenten.

"Hinata go save the others, they are what really matters." said Naruto as Hinata looked down.

"Alright." said Hinata as she slowly walked away.

"Well I am going to go run whatever tests we can run on the blood." Said Ino

"What about you Sakura?" asked Temari

"I am going to read the medical files from the Leaf." said Sakura "See what we are dealing with on the medical front."

"Alright." said everyone as they left. Naruto could hear them walk away followed by the sound of a door closing, meaning Naruto was alone again. Suddenly he heard the sound of something hitting metal.

"You still with me Naruto?" asked Sakura voice from the other side of the door.

"I thought you left with the others?" asked Naruto as he stood up and walked toward the door. He looked out the window to see Sakura's feet near the other door. Form their position Naruto figured Sakura was sitting with her back against the metal door.

"I can read anywhere so I might as well keep you company." answered Sakura as she opened up scrolls and started reading. She could hear Naruto moving on the other side of the door as he sat with his back to the door. Solid steel door was all that separated Naruto and Sakura. For a while no one said anything as Sakura started to read the data from the Leaf.

"Sakura can I ask you a question?" asked Naruto

"Of course." said Sakura

"Is there anything I can do to help?" asked Naruto

"Naruto-kun must be board out his mind sitting in there with nothing to do but look at his arm." thought Sakura "He can't go out and train like he normally does."

"There may be one thing." said Sakura "I didn't have a chance to check you out for any other changes apart from your arm, eyes and teeth. So if you can give yourself a look over to see if there is any more changes."

"Alright." said Naruto as he stood up. Sakura listened as Naruto take off his shirt and unbuckle his belt.

"Just think Naruto-kun is undressing right now…we can accidently stand up and watch him." Said Inner Sakura

"No…I am not a pervert." thought Sakura

"Ya, right what about the dream you had a couple nights ago involving both Naruto, you and several of Naruto's shadow clones. Doing things that would be too perverted for even Jiriaya's books." replied Inner Sakura with a perverted grin as Sakura blushed deeper than she ever thought possible.

"That is personal…." snapped Sakura

"I am your inner self, I voice your deepest darkest dirties ideas." Said Inner Sakura

"Sakura." said Naruto's voice snapping Sakura out of her argument with her inner self

"Yes, Naruto." said Sakura "Did you find something?"

"Yes." said Naruto

"Well what is it?"

"Well it is kind of hard to explain but my chest muscles are bigger." said Naruto

"What?" asked Sakura wondering what Naruto was talking about.

"Take a look." said Naruto as Sakura sat up and looked inside the room. Instantly she blushed as she saw Naruto. He was dressed in only a pair of tight orange boxers, so tight that Sakura could see a large lump in the front of his boxers.

"My God." thought Sakura as she looked up at the six pack chest and defined arm muscles. Sakura knew that she would be dreaming about his body when she closed her eyes tonight.

"Do you see?" asked Naruto as he looked down at his chest.

"Oh ya we see, you are the by far the hottest man ever given by God to the world." said Inner Sakura

"I see you work out." said Sakura as Naruto looked up at her, he blushed a little bit.

"Ya, but they a too large." said Naruto "I was trying to get to this but I wasn't close to this. It is like I am adding muscles."

"Crap, that was in the notes." thought Sakura as she looked down at the file. There in Tsunade's own handwriting

Anyone who is infected by the virus adds weight and height at an unheard of rate, whole new muscles groups form within the body." read Sakura "People in poor physical shape before the turn become physically fit and those who are fit become extremely strong and fast."

"Do you know what is going on?" asked Naruto

"It seems that is part of the turning process." said Sakura "It seems that people get stronger when they turn."

"I guess that explains why Sasuke could break out from jail." said Naruto

"Sasuke escaped?" asked Sakura

"Ya, didn't I tell you?" asked Naruto "That was the thing I didn't have time to inform Tsunade about before I left for the mission."

"No you didn't tell us." said Sakura

"Sorry." Said Naruto

"Don't worry about it you where distracted by your situation." said Sakura as Naruto started putting his close back on. "Well Sasuke is the snake he always was before."

"He isn't a snake Sakura." Stated Naruto

"Please you still can't defend him; he is a snake in all the ways that matters." said Sakura

"No…he didn't turn into a snake." Said Naruto

Flashback the Morning of the outbreak.

"Morning sir." said a female ANBU as Naruto approached a large metal door hidden in the ANBU headquarters.

"Morning, isn't there suppose to be two ANBU outside the door at all times?" asked Naruto as the ANBU shock her head.

"Sorry about that sir, but my captain started feeling sick and none of the medical pills where working. So he went to the medical center." said the ANBU "He should be back soon."

"Ok I will let it slide this time." said Naruto as he walked through the door. Instantly he found himself in a darkened corridor. He walked down the darkened corridor until he came to the very end of the hallway. There behind solid metal bars and chakra suppressing seals sat one Sasuke Uchiha. He sat in the very back of the room, so most of his body was hidden under shadows.

"Hello Naruto came to see if I had seen the errors of my ways?" asked Sasuke in a deeper voice.

"No, I came to ask how your eyesight is doing?" asked Naruto "Sakura did her best to restore your sight after you began losing it."

"That pink bitch sealed my Sharingan away, I would rather be as blind as a bat then lose my Sharingan." stated Sasuke still in that deeper voice.

"Sasuke your voice is different is something wrong?" asked Naruto as Sasuke began to laugh a bit.

"No everything is perrrrfect." said Sasuke stressing the r. Slowly Naruto reached over toward a light switch and turned the lights on to full strength inside the cell. Instantly his eyes widened as he saw Sasuke.

He had changed in ways Naruto had never thought possible, His skin was covered with jet black fur, his head hair now blended into the black fur. Two cat like ears where on the top of his head. He was adding weight extremely fast as he added muscles almost at the same rate. His chest pushed out so much Naruto could see each muscle under the black fur. Sasuke stood up, his head touching the seven foot high roof. His legs where changing into something more animal like as he walked toward the bars. A long black tail formed from the base of his spine. Sasuke's face had pushed out into a short cat muzzle leaned down to look Naruto in the eyes with his now silted cat eyes.

"What the hell is happening to you?" asked Naruto as Sasuke grinned as much as he could with his cat like face. Showing his large fangs

"It has begun and it will change the world as you know it." said Sasuke as he ran his hand across the bars. His hand looked mostly human until suddenly five claws came shooting out from within his body. Instantly he cut though half the bars.

"I will get help." said Naruto as he ran down the hallway.

"There is no place you can run too dead last, it has begun." stated Sasuke as Naruto reached the main doors. He rushed out the door and expected to find an ANBU team waiting. However what he found was the female guard on the ground with a bloody kunai in her hand and blood running down her arm.

"What is going on?" asked Naruto

"I was attacked." said the ANBU

"By what?" asked Naruto

"You may find it hard to believe but it was a human rhino." said the ANBU "I stabbed him but not before he bit me. I know it is crazy but it's true."

"You are not crazy." said Naruto as he looked back down the hallway to see metal bars fall onto the floor. "Let's go inform the Hokage."

End Flashback

"However we never got to inform Tsunade, Shizune meet us and gave us orders from Tsunade to protect the villagers while she worked on a cure." said Naruto

"So Sasuke is a big cat?" asked Sakura

"Ya, a panther I think." said Naruto

"Why would he become a cat? Why not a snake?" asked Sakura "A snake would fit his personality."

"I never saw a snake or anything beside a mammal." said Naruto

"So people only turn into mammals." thought Sakura "It would make sense no virus would ever be able to replace human DNA with anything other than mammals the DNA would destroy itself within hours killing the people who turned. However mammal DNA patterns are close so it would be possible to have them mix."

Suddenly the sound of footsteps coming down toward them caused Sakura to look toward the staircase to see Ino walking toward them.

"Sakura what are you doing here?" asked Ino

"I wanted to keep Naruto company and I can read anywhere." explained Sakura

"Alright." said Ino "then why are you looking though the bars?"

"I asked her too." answered Naruto "I wanted her to see my muscles."

"Naruto if Hinata was here she would have slapped you." laughed Ino

"It's not that way." answered Naruto "My muscles are changing with this virus."

"I see." said Ino as she looked at the blushing Sakura.

"Besides Hinata and I are not dating right now." added Naruto

"So why are you here?" asked Sakura

"Well…it isn't anything good." said Ino "I ran Naruto's blood though a test to find out what you are becoming."

"You can do that?" asked Naruto

"It was one of Lady Tsunade's breakthroughs." said Ino "So do you want to know what it is?"

For a while nothing happened as Naruto thought about if he wanted to know.

"I guess I will find out sooner or later." said Naruto "But I have a feeling I know what it is."

"Naruto you are becoming a fox." said Ino as Naruto lowered his head and started acting like a person who had gotten the news they have cancer.

"I knew it." said Naruto "The Kyuubi fucks me over even after I got rid of him."

Flashback

"Naruto are you sure you want to do this?" asked Tsunade as Naruto stood in front of her in her office. "There is a chance you could die."

"Yes, I have had this demon in me for 19 years and I want it out of me." said Naruto "This seal will allow me to absorb over half the Kyuubi's power within me and destroy the other half along with the Kyuubi."

"Alright then I will make the arrangement." said Tsunade

End Flashback

"A Fox…a fucking fox." said Naruto as went to sit down on the bed. "Just fucking….perfect."

"Naruto it's going to be ok." said Sakura as she watched Naruto sit on the bed looking at the ground. Every fiber in her body wanted to reach out and comfort him but as she reached for the door handle Ino stopped her.

"You can't comfort him Sakura." whispered Ino as she grabbed Sakura's hand. "Let him work it out himself and then comfort him."

"But…." said Sakura

"No buts." ordered Ino as she started dragging Sakura away.

I am sorry for being late in updating a mix of school work combined with Halo Reach took a lot of my time. I hope I can be forgiven for the lateness of the chapter. Now until next time keep reading. Thanks Wilkins75.
