A/N: Man, it's been a while, huh? Seriously, it's been a pretty long time. I couldn't be able to update as quickly as possible mainly because of 4chan. That place really eats up your time. To those who have been waiting patiently, I'm sorry I took such a long time. Hopefully, I won't be as delayed in the works. Enjoy the chapter!

Chapter 6 – Beginner Steps

As Finn woke up inside the Animus system, he was at the point in which he was last in. His body also changed to that of Altaïr's. When the Animus system recognized him and his last save point, the female voice returned.

"Welcome back, Subject Finn." said the voice. "We will now continue with the tutorial on controlling your ancestor."

"Okay, I'm ready." replied Finn, as he spoke in Altaïr's voice.

"Scanning for device." said the voice, as the system began to scan for a controller. After detecting Beemo's controller, the voice said, "Compatible controller device found. Begin controller button mapping to system."

As the system began to implement the controls, Finn began to feel and grip the control of Altaïr as he became one with him.

"Controller mapping complete." said the voice. "Subject can now control the Ancestor."

"Awesome!" replied Finn. "I'm ready to learn… the ways of the Assassin."

"We shall now begin the tutorial." said the voice.

After several hours of many stressful attempts, Finn completed the tutorial levels, as well as gaining knowledge of the basic techniques that the Assassins use. He also gained synchronization with his ancestor, allowing him to unlock memories.

"Man, was that crazy!" said Finn, as he was exhausted from the tutorials. "How can these guys be so quick and silent?"

"Well done on completing the tutorials." said the voice. "You are now able to access to your ancestor's memories. If you should forget how to control your ancestor, you can begin the tutorials at any time in the main menu."

"Okay, I'll keep that in mind." said Finn.

"You will now exit to the main menu." said the voice.

A growing flash began to emanate and Finn's mind was sent back to reality. As he went back to the real world, Finn got off the Animus device.

Jake then walked towards him as he said, "Hey Finn, how was the training?"

"It was actually hard to learn, but I think I got the hang of using the techniques." said Finn.

"Well that's great, bro!" said Jake. "We should talk to Bubblegum and see what we should do next."

"Okay." said Finn. Then he asked curiously, "Hey Jake, what time is it?"

"Adventure time?" said Jake jokingly.

"Dude, seriously." said Finn. "What time is it?"

"Oh, it's uh… 2:17 PM." said Jake, as he checked his phone.

"Oh crap, I spent that much time on the Animus?" said Finn shockingly. "Wow…"

He paused for a moment, as he looked around his surroundings. He then continued saying, "Well, let's go with Bubblegum."

As they walked towards Princess Bubblegum and Marceline, who were by the Animus console, Finn and Jake asked, "So, what do we do next?"

"Well, Finn, you can either continue to use the Animus or take a rest and we'll continue later in the evening." said Princess Bubblegum.

"Well, I say that you should take the rest, Finn." said Marceline. "Bonnibel is working pretty hard trying to understand this nerd junk or whatever."

"Well, okay." said Finn. "I could take a break from using the Animus. I guess I'll check out the place and see what there is to find." He turned to Jake and said, "Come on, Jake. Let's explore the place upstairs."

"Alright, man." said Jake. "Upstairs we go!"

They left the Animus room, went to the staircase and walked up to what is left of the top of the building. The roof was partially removed. There were several items and other knickknacks on the floor, as well as the remains of human skeletons. Finn and Jake searched the place as they tried finding anything useful for themselves or for Princess Bubblegum. As Finn looked inside a briefcase, he found an interesting item.

"Hey Jake!" called Finn. "Check it out! I found something really math!"

"What is it?" replied Jake.

"Check it, it's a sweet new weapon!" said Finn, as he opened the briefcase and revealed a Hidden Blade.

"Whoa! What's that?" asked Jake.

"It's a Hidden Blade, a weapon used by the Assassins to assassinate their enemies." said Finn. "I used one in the tutorial, so I'll take this one with me as a new weapon to keep."

Finn grabbed the Hidden Blade and placed the brace on his wrist. As he tinkered with the mechanisms, he got it to work.

"This is awesome!" said Finn. "I'm going to start using this when we go on adventures."

As he toyed around with his new piece of weaponry, Finn looked around the place for any more interesting things.

After two hours of looking in the roof level and the rest of the upper floors, they began to walk down to the floor where the Animus room is. As they were walking, Jake began to speak.

"Dude, you look cool with that Hidden Blade on your arm!" commented Jake.

"I know!" said Finn. "It feels like an extension on me. Like if it was a new part of my arm."

"Hey Finn, I got an idea." said Jake.

"Okay, shoot." said Finn.

"You should practice using those Assassin skills in the real world at any chance you could get." said Jake. "After using the Animus, if possible; sometime before we all go to bed; when you wake up; and some other times. You need to hone those skills if you wanna get good at them so we can use them in adventures."

"That's a good idea, Jake." said Finn. "But let's begin tomorrow, because today I want to see how Altaïr's life was like when I go into the Animus."

"Okay, bro." said Jake. "Tomorrow it is then."

Finn and Jake entered the room. As they walked, they found Princess Bubblegum and Marceline talking to each other.

"What's going on, ladies?" said Finn.

"Nothing." replied Princess Bubblegum. "We were just talking about ourselves."

"No need to get talk about the details." said Marceline. "But you should start getting ready, Finn. I wanna see what you're made of and get ready for the first memory."

"Okay." said Finn.

"Hold on." said Princess Bubblegum, as she saw the Hidden Blade on Finn's arm. She walked towards him and grabbed his arm.

"What is this, Finn?" she asked.

Finn blushed a little, as he began, "Oh, uh… this is a Hidden Blade. It's a weapon that the Assassins used to strike their enemies out."

"Yeah, he found it while we were looking on the roof for anything interesting." said Jake.

"I see." said Princess Bubblegum. "Well, you should get on the Animus now."

Finn walked towards the Animus and laid himself upon the machine. Princess Bubblegum activated the system, and the glass face screen popped out.

"Good luck, Finn." said Princess Bubblegum.

"Hope you kick some ass, Finn!" said Jake.

"When you wake up, show us how the blade works!" said Marceline.

The screen lighted up, and sent Finn's mind into the digital world.
